+1,674 @@ + GNU GENERAL PUBLIC LICENSE + Version 3, 29 June 2007 + + Copyright (C) 2007 Free Software Foundation, Inc. + Everyone is permitted to copy and distribute verbatim copies + of this license document, but changing it is not allowed. + + Preamble + + The GNU General Public License is a free, copyleft license for +software and other kinds of works. + + The licenses for most software and other practical works are designed +to take away your freedom to share and change the works. By contrast, +the GNU General Public License is intended to guarantee your freedom to +share and change all versions of a program--to make sure it remains free +software for all its users. We, the Free Software Foundation, use the +GNU General Public License for most of our software; it applies also to +any other work released this way by its authors. You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +them if you wish), that you receive source code or can get it if you +want it, that you can change the software or use pieces of it in new +free programs, and that you know you can do these things. + + To protect your rights, we need to prevent others from denying you +these rights or asking you to surrender the rights. Therefore, you have +certain responsibilities if you distribute copies of the software, or if +you modify it: responsibilities to respect the freedom of others. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must pass on to the recipients the same +freedoms that you received. You must make sure that they, too, receive +or can get the source code. And you must show them these terms so they +know their rights. + + Developers that use the GNU GPL protect your rights with two steps: +(1) assert copyright on the software, and (2) offer you this License +giving you legal permission to copy, distribute and/or modify it. + + For the developers' and authors' protection, the GPL clearly explains +that there is no warranty for this free software. For both users' and +authors' sake, the GPL requires that modified versions be marked as +changed, so that their problems will not be attributed erroneously to +authors of previous versions. + + Some devices are designed to deny users access to install or run +modified versions of the software inside them, although the manufacturer +can do so. This is fundamentally incompatible with the aim of +protecting users' freedom to change the software. The systematic +pattern of such abuse occurs in the area of products for individuals to +use, which is precisely where it is most unacceptable. Therefore, we +have designed this version of the GPL to prohibit the practice for those +products. If such problems arise substantially in other domains, we +stand ready to extend this provision to those domains in future versions +of the GPL, as needed to protect the freedom of users. + + Finally, every program is threatened constantly by software patents. +States should not allow patents to restrict development and use of +software on general-purpose computers, but in those that do, we wish to +avoid the special danger that patents applied to a free program could +make it effectively proprietary. To prevent this, the GPL assures that +patents cannot be used to render the program non-free. + + The precise terms and conditions for copying, distribution and +modification follow. + + TERMS AND CONDITIONS + + 0. Definitions. + + "This License" refers to version 3 of the GNU General Public License. + + "Copyright" also means copyright-like laws that apply to other kinds of +works, such as semiconductor masks. + + "The Program" refers to any copyrightable work licensed under this +License. Each licensee is addressed as "you". "Licensees" and +"recipients" may be individuals or organizations. + + To "modify" a work means to copy from or adapt all or part of the work +in a fashion requiring copyright permission, other than the making of an +exact copy. The resulting work is called a "modified version" of the +earlier work or a work "based on" the earlier work. + + A "covered work" means either the unmodified Program or a work based +on the Program. + + To "propagate" a work means to do anything with it that, without +permission, would make you directly or secondarily liable for +infringement under applicable copyright law, except executing it on a +computer or modifying a private copy. Propagation includes copying, +distribution (with or without modification), making available to the +public, and in some countries other activities as well. + + To "convey" a work means any kind of propagation that enables other +parties to make or receive copies. Mere interaction with a user through +a computer network, with no transfer of a copy, is not conveying. + + An interactive user interface displays "Appropriate Legal Notices" +to the extent that it includes a convenient and prominently visible +feature that (1) displays an appropriate copyright notice, and (2) +tells the user that there is no warranty for the work (except to the +extent that warranties are provided), that licensees may convey the +work under this License, and how to view a copy of this License. If +the interface presents a list of user commands or options, such as a +menu, a prominent item in the list meets this criterion. + + 1. Source Code. + + The "source code" for a work means the preferred form of the work +for making modifications to it. "Object code" means any non-source +form of a work. + + A "Standard Interface" means an interface that either is an official +standard defined by a recognized standards body, or, in the case of +interfaces specified for a particular programming language, one that +is widely used among developers working in that language. + + The "System Libraries" of an executable work include anything, other +than the work as a whole, that (a) is included in the normal form of +packaging a Major Component, but which is not part of that Major +Component, and (b) serves only to enable use of the work with that +Major Component, or to implement a Standard Interface for which an +implementation is available to the public in source code form. A +"Major Component", in this context, means a major essential component +(kernel, window system, and so on) of the specific operating system +(if any) on which the executable work runs, or a compiler used to +produce the work, or an object code interpreter used to run it. + + The "Corresponding Source" for a work in object code form means all +the source code needed to generate, install, and (for an executable +work) run the object code and to modify the work, including scripts to +control those activities. However, it does not include the work's +System Libraries, or general-purpose tools or generally available free +programs which are used unmodified in performing those activities but +which are not part of the work. For example, Corresponding Source +includes interface definition files associated with source files for +the work, and the source code for shared libraries and dynamically +linked subprograms that the work is specifically designed to require, +such as by intimate data communication or control flow between those +subprograms and other parts of the work. + + The Corresponding Source need not include anything that users +can regenerate automatically from other parts of the Corresponding +Source. + + The Corresponding Source for a work in source code form is that +same work. + + 2. Basic Permissions. + + All rights granted under this License are granted for the term of +copyright on the Program, and are irrevocable provided the stated +conditions are met. This License explicitly affirms your unlimited +permission to run the unmodified Program. The output from running a +covered work is covered by this License only if the output, given its +content, constitutes a covered work. This License acknowledges your +rights of fair use or other equivalent, as provided by copyright law. + + You may make, run and propagate covered works that you do not +convey, without conditions so long as your license otherwise remains +in force. You may convey covered works to others for the sole purpose +of having them make modifications exclusively for you, or provide you +with facilities for running those works, provided that you comply with +the terms of this License in conveying all material for which you do +not control copyright. Those thus making or running the covered works +for you must do so exclusively on your behalf, under your direction +and control, on terms that prohibit them from making any copies of +your copyrighted material outside their relationship with you. + + Conveying under any other circumstances is permitted solely under +the conditions stated below. Sublicensing is not allowed; section 10 +makes it unnecessary. + + 3. Protecting Users' Legal Rights From Anti-Circumvention Law. + + No covered work shall be deemed part of an effective technological +measure under any applicable law fulfilling obligations under article +11 of the WIPO copyright treaty adopted on 20 December 1996, or +similar laws prohibiting or restricting circumvention of such +measures. + + When you convey a covered work, you waive any legal power to forbid +circumvention of technological measures to the extent such circumvention +is effected by exercising rights under this License with respect to +the covered work, and you disclaim any intention to limit operation or +modification of the work as a means of enforcing, against the work's +users, your or third parties' legal rights to forbid circumvention of +technological measures. + + 4. Conveying Verbatim Copies. + + You may convey verbatim copies of the Program's source code as you +receive it, in any medium, provided that you conspicuously and +appropriately publish on each copy an appropriate copyright notice; +keep intact all notices stating that this License and any +non-permissive terms added in accord with section 7 apply to the code; +keep intact all notices of the absence of any warranty; and give all +recipients a copy of this License along with the Program. + + You may charge any price or no price for each copy that you convey, +and you may offer support or warranty protection for a fee. + + 5. Conveying Modified Source Versions. + + You may convey a work based on the Program, or the modifications to +produce it from the Program, in the form of source code under the +terms of section 4, provided that you also meet all of these conditions: + + a) The work must carry prominent notices stating that you modified + it, and giving a relevant date. + + b) The work must carry prominent notices stating that it is + released under this License and any conditions added under section + 7. This requirement modifies the requirement in section 4 to + "keep intact all notices". + + c) You must license the entire work, as a whole, under this + License to anyone who comes into possession of a copy. This + License will therefore apply, along with any applicable section 7 + additional terms, to the whole of the work, and all its parts, + regardless of how they are packaged. This License gives no + permission to license the work in any other way, but it does not + invalidate such permission if you have separately received it. + + d) If the work has interactive user interfaces, each must display + Appropriate Legal Notices; however, if the Program has interactive + interfaces that do not display Appropriate Legal Notices, your + work need not make them do so. + + A compilation of a covered work with other separate and independent +works, which are not by their nature extensions of the covered work, +and which are not combined with it such as to form a larger program, +in or on a volume of a storage or distribution medium, is called an +"aggregate" if the compilation and its resulting copyright are not +used to limit the access or legal rights of the compilation's users +beyond what the individual works permit. Inclusion of a covered work +in an aggregate does not cause this License to apply to the other +parts of the aggregate. + + 6. Conveying Non-Source Forms. + + You may convey a covered work in object code form under the terms +of sections 4 and 5, provided that you also convey the +machine-readable Corresponding Source under the terms of this License, +in one of these ways: + + a) Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by the + Corresponding Source fixed on a durable physical medium + customarily used for software interchange. + + b) Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by a + written offer, valid for at least three years and valid for as + long as you offer spare parts or customer support for that product + model, to give anyone who possesses the object code either (1) a + copy of the Corresponding Source for all the software in the + product that is covered by this License, on a durable physical + medium customarily used for software interchange, for a price no + more than your reasonable cost of physically performing this + conveying of source, or (2) access to copy the + Corresponding Source from a network server at no charge. + + c) Convey individual copies of the object code with a copy of the + written offer to provide the Corresponding Source. This + alternative is allowed only occasionally and noncommercially, and + only if you received the object code with such an offer, in accord + with subsection 6b. + + d) Convey the object code by offering access from a designated + place (gratis or for a charge), and offer equivalent access to the + Corresponding Source in the same way through the same place at no + further charge. You need not require recipients to copy the + Corresponding Source along with the object code. If the place to + copy the object code is a network server, the Corresponding Source + may be on a different server (operated by you or a third party) + that supports equivalent copying facilities, provided you maintain + clear directions next to the object code saying where to find the + Corresponding Source. Regardless of what server hosts the + Corresponding Source, you remain obligated to ensure that it is + available for as long as needed to satisfy these requirements. + + e) Convey the object code using peer-to-peer transmission, provided + you inform other peers where the object code and Corresponding + Source of the work are being offered to the general public at no + charge under subsection 6d. + + A separable portion of the object code, whose source code is excluded +from the Corresponding Source as a System Library, need not be +included in conveying the object code work. + + A "User Product" is either (1) a "consumer product", which means any +tangible personal property which is normally used for personal, family, +or household purposes, or (2) anything designed or sold for incorporation +into a dwelling. In determining whether a product is a consumer product, +doubtful cases shall be resolved in favor of coverage. For a particular +product received by a particular user, "normally used" refers to a +typical or common use of that class of product, regardless of the status +of the particular user or of the way in which the particular user +actually uses, or expects or is expected to use, the product. A product +is a consumer product regardless of whether the product has substantial +commercial, industrial or non-consumer uses, unless such uses represent +the only significant mode of use of the product. + + "Installation Information" for a User Product means any methods, +procedures, authorization keys, or other information required to install +and execute modified versions of a covered work in that User Product from +a modified version of its Corresponding Source. The information must +suffice to ensure that the continued functioning of the modified object +code is in no case prevented or interfered with solely because +modification has been made. + + If you convey an object code work under this section in, or with, or +specifically for use in, a User Product, and the conveying occurs as +part of a transaction in which the right of possession and use of the +User Product is transferred to the recipient in perpetuity or for a +fixed term (regardless of how the transaction is characterized), the +Corresponding Source conveyed under this section must be accompanied +by the Installation Information. But this requirement does not apply +if neither you nor any third party retains the ability to install +modified object code on the User Product (for example, the work has +been installed in ROM). + + The requirement to provide Installation Information does not include a +requirement to continue to provide support service, warranty, or updates +for a work that has been modified or installed by the recipient, or for +the User Product in which it has been modified or installed. Access to a +network may be denied when the modification itself materially and +adversely affects the operation of the network or violates the rules and +protocols for communication across the network. + + Corresponding Source conveyed, and Installation Information provided, +in accord with this section must be in a format that is publicly +documented (and with an implementation available to the public in +source code form), and must require no special password or key for +unpacking, reading or copying. + + 7. Additional Terms. + + "Additional permissions" are terms that supplement the terms of this +License by making exceptions from one or more of its conditions. +Additional permissions that are applicable to the entire Program shall +be treated as though they were included in this License, to the extent +that they are valid under applicable law. If additional permissions +apply only to part of the Program, that part may be used separately +under those permissions, but the entire Program remains governed by +this License without regard to the additional permissions. + + When you convey a copy of a covered work, you may at your option +remove any additional permissions from that copy, or from any part of +it. (Additional permissions may be written to require their own +removal in certain cases when you modify the work.) You may place +additional permissions on material, added by you to a covered work, +for which you have or can give appropriate copyright permission. + + Notwithstanding any other provision of this License, for material you +add to a covered work, you may (if authorized by the copyright holders of +that material) supplement the terms of this License with terms: + + a) Disclaiming warranty or limiting liability differently from the + terms of sections 15 and 16 of this License; or + + b) Requiring preservation of specified reasonable legal notices or + author attributions in that material or in the Appropriate Legal + Notices displayed by works containing it; or + + c) Prohibiting misrepresentation of the origin of that material, or + requiring that modified versions of such material be marked in + reasonable ways as different from the original version; or + + d) Limiting the use for publicity purposes of names of licensors or + authors of the material; or + + e) Declining to grant rights under trademark law for use of some + trade names, trademarks, or service marks; or + + f) Requiring indemnification of licensors and authors of that + material by anyone who conveys the material (or modified versions of + it) with contractual assumptions of liability to the recipient, for + any liability that these contractual assumptions directly impose on + those licensors and authors. + + All other non-permissive additional terms are considered "further +restrictions" within the meaning of section 10. If the Program as you +received it, or any part of it, contains a notice stating that it is +governed by this License along with a term that is a further +restriction, you may remove that term. If a license document contains +a further restriction but permits relicensing or conveying under this +License, you may add to a covered work material governed by the terms +of that license document, provided that the further restriction does +not survive such relicensing or conveying. + + If you add terms to a covered work in accord with this section, you +must place, in the relevant source files, a statement of the +additional terms that apply to those files, or a notice indicating +where to find the applicable terms. + + Additional terms, permissive or non-permissive, may be stated in the +form of a separately written license, or stated as exceptions; +the above requirements apply either way. + + 8. Termination. + + You may not propagate or modify a covered work except as expressly +provided under this License. Any attempt otherwise to propagate or +modify it is void, and will automatically terminate your rights under +this License (including any patent licenses granted under the third +paragraph of section 11). + + However, if you cease all violation of this License, then your +license from a particular copyright holder is reinstated (a) +provisionally, unless and until the copyright holder explicitly and +finally terminates your license, and (b) permanently, if the copyright +holder fails to notify you of the violation by some reasonable means +prior to 60 days after the cessation. + + Moreover, your license from a particular copyright holder is +reinstated permanently if the copyright holder notifies you of the +violation by some reasonable means, this is the first time you have +received notice of violation of this License (for any work) from that +copyright holder, and you cure the violation prior to 30 days after +your receipt of the notice. + + Termination of your rights under this section does not terminate the +licenses of parties who have received copies or rights from you under +this License. If your rights have been terminated and not permanently +reinstated, you do not qualify to receive new licenses for the same +material under section 10. + + 9. Acceptance Not Required for Having Copies. + + You are not required to accept this License in order to receive or +run a copy of the Program. Ancillary propagation of a covered work +occurring solely as a consequence of using peer-to-peer transmission +to receive a copy likewise does not require acceptance. However, +nothing other than this License grants you permission to propagate or +modify any covered work. These actions infringe copyright if you do +not accept this License. Therefore, by modifying or propagating a +covered work, you indicate your acceptance of this License to do so. + + 10. Automatic Licensing of Downstream Recipients. + + Each time you convey a covered work, the recipient automatically +receives a license from the original licensors, to run, modify and +propagate that work, subject to this License. You are not responsible +for enforcing compliance by third parties with this License. + + An "entity transaction" is a transaction transferring control of an +organization, or substantially all assets of one, or subdividing an +organization, or merging organizations. If propagation of a covered +work results from an entity transaction, each party to that +transaction who receives a copy of the work also receives whatever +licenses to the work the party's predecessor in interest had or could +give under the previous paragraph, plus a right to possession of the +Corresponding Source of the work from the predecessor in interest, if +the predecessor has it or can get it with reasonable efforts. + + You may not impose any further restrictions on the exercise of the +rights granted or affirmed under this License. For example, you may +not impose a license fee, royalty, or other charge for exercise of +rights granted under this License, and you may not initiate litigation +(including a cross-claim or counterclaim in a lawsuit) alleging that +any patent claim is infringed by making, using, selling, offering for +sale, or importing the Program or any portion of it. + + 11. Patents. + + A "contributor" is a copyright holder who authorizes use under this +License of the Program or a work on which the Program is based. The +work thus licensed is called the contributor's "contributor version". + + A contributor's "essential patent claims" are all patent claims +owned or controlled by the contributor, whether already acquired or +hereafter acquired, that would be infringed by some manner, permitted +by this License, of making, using, or selling its contributor version, +but do not include claims that would be infringed only as a +consequence of further modification of the contributor version. For +purposes of this definition, "control" includes the right to grant +patent sublicenses in a manner consistent with the requirements of +this License. + + Each contributor grants you a non-exclusive, worldwide, royalty-free +patent license under the contributor's essential patent claims, to +make, use, sell, offer for sale, import and otherwise run, modify and +propagate the contents of its contributor version. + + In the following three paragraphs, a "patent license" is any express +agreement or commitment, however denominated, not to enforce a patent +(such as an express permission to practice a patent or covenant not to +sue for patent infringement). To "grant" such a patent license to a +party means to make such an agreement or commitment not to enforce a +patent against the party. + + If you convey a covered work, knowingly relying on a patent license, +and the Corresponding Source of the work is not available for anyone +to copy, free of charge and under the terms of this License, through a +publicly available network server or other readily accessible means, +then you must either (1) cause the Corresponding Source to be so +available, or (2) arrange to deprive yourself of the benefit of the +patent license for this particular work, or (3) arrange, in a manner +consistent with the requirements of this License, to extend the patent +license to downstream recipients. "Knowingly relying" means you have +actual knowledge that, but for the patent license, your conveying the +covered work in a country, or your recipient's use of the covered work +in a country, would infringe one or more identifiable patents in that +country that you have reason to believe are valid. + + If, pursuant to or in connection with a single transaction or +arrangement, you convey, or propagate by procuring conveyance of, a +covered work, and grant a patent license to some of the parties +receiving the covered work authorizing them to use, propagate, modify +or convey a specific copy of the covered work, then the patent license +you grant is automatically extended to all recipients of the covered +work and works based on it. + + A patent license is "discriminatory" if it does not include within +the scope of its coverage, prohibits the exercise of, or is +conditioned on the non-exercise of one or more of the rights that are +specifically granted under this License. You may not convey a covered +work if you are a party to an arrangement with a third party that is +in the business of distributing software, under which you make payment +to the third party based on the extent of your activity of conveying +the work, and under which the third party grants, to any of the +parties who would receive the covered work from you, a discriminatory +patent license (a) in connection with copies of the covered work +conveyed by you (or copies made from those copies), or (b) primarily +for and in connection with specific products or compilations that +contain the covered work, unless you entered into that arrangement, +or that patent license was granted, prior to 28 March 2007. + + Nothing in this License shall be construed as excluding or limiting +any implied license or other defenses to infringement that may +otherwise be available to you under applicable patent law. + + 12. No Surrender of Others' Freedom. + + If conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot convey a +covered work so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you may +not convey it at all. For example, if you agree to terms that obligate you +to collect a royalty for further conveying from those to whom you convey +the Program, the only way you could satisfy both those terms and this +License would be to refrain entirely from conveying the Program. + + 13. Use with the GNU Affero General Public License. + + Notwithstanding any other provision of this License, you have +permission to link or combine any covered work with a work licensed +under version 3 of the GNU Affero General Public License into a single +combined work, and to convey the resulting work. The terms of this +License will continue to apply to the part which is the covered work, +but the special requirements of the GNU Affero General Public License, +section 13, concerning interaction through a network will apply to the +combination as such. + + 14. Revised Versions of this License. + + The Free Software Foundation may publish revised and/or new versions of +the GNU General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + + Each version is given a distinguishing version number. If the +Program specifies that a certain numbered version of the GNU General +Public License "or any later version" applies to it, you have the +option of following the terms and conditions either of that numbered +version or of any later version published by the Free Software +Foundation. If the Program does not specify a version number of the +GNU General Public License, you may choose any version ever published +by the Free Software Foundation. + + If the Program specifies that a proxy can decide which future +versions of the GNU General Public License can be used, that proxy's +public statement of acceptance of a version permanently authorizes you +to choose that version for the Program. + + Later license versions may give you additional or different +permissions. However, no additional obligations are imposed on any +author or copyright holder as a result of your choosing to follow a +later version. + + 15. Disclaimer of Warranty. + + THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY +APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT +HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY +OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, +THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR +PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM +IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF +ALL NECESSARY SERVICING, REPAIR OR CORRECTION. + + 16. Limitation of Liability. + + IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS +THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY +GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE +USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF +DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD +PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), +EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF +SUCH DAMAGES. + + 17. Interpretation of Sections 15 and 16. + + If the disclaimer of warranty and limitation of liability provided +above cannot be given local legal effect according to their terms, +reviewing courts shall apply local law that most closely approximates +an absolute waiver of all civil liability in connection with the +Program, unless a warranty or assumption of liability accompanies a +copy of the Program in return for a fee. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +state the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + + Copyright (C) + + This program is free software: you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation, either version 3 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the + GNU General Public License for more details. + + You should have received a copy of the GNU General Public License + along with this program. If not, see . + +Also add information on how to contact you by electronic and paper mail. + + If the program does terminal interaction, make it output a short +notice like this when it starts in an interactive mode: + + Copyright (C) + This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. + This is free software, and you are welcome to redistribute it + under certain conditions; type `show c' for details. + +The hypothetical commands `show w' and `show c' should show the appropriate +parts of the General Public License. Of course, your program's commands +might be different; for a GUI interface, you would use an "about box". + + You should also get your employer (if you work as a programmer) or school, +if any, to sign a "copyright disclaimer" for the program, if necessary. +For more information on this, and how to apply and follow the GNU GPL, see +. + + The GNU General Public License does not permit incorporating your program +into proprietary programs. If your program is a subroutine library, you +may consider it more useful to permit linking proprietary applications with +the library. If this is what you want to do, use the GNU Lesser General +Public License instead of this License.

This means that you register +handlers with the parser before starting the parse. These handlers +are called when the parser discovers the associated structures in the +document being parsed. A start tag is an example of the kind of +structures for which you may register handlers. + +Windows users should use the +[`expat_win32` package](https://sourceforge.net/projects/expat/files/expat_win32/), +which includes both precompiled libraries and executables, and source code for +developers. + +Expat is [free software](https://www.gnu.org/philosophy/free-sw.en.html). +You may copy, distribute, and modify it under the terms of the License +contained in the file +[`COPYING`](https://github.com/libexpat/libexpat/blob/master/expat/COPYING) +distributed with this package. +This license is the same as the MIT/X Consortium license. + +If you are building Expat from a check-out from the +[Git repository](https://github.com/libexpat/libexpat/), +you need to run a script that generates the configure script using the +GNU autoconf and libtool tools. To do this, you need to have +autoconf 2.58 or newer. Run the script like this: + +```console +./buildconf.sh +``` + +Once this has been done, follow the same instructions as for building +from a source distribution. + +To build Expat from a source distribution, you first run the +configuration shell script in the top level distribution directory: + +```console +./configure +``` + +There are many options which you may provide to configure (which you +can discover by running configure with the `--help` option). But the +one of most interest is the one that sets the installation directory. +By default, the configure script will set things up to install +libexpat into `/usr/local/lib`, `expat.h` into `/usr/local/include`, and +`xmlwf` into `/usr/local/bin`. If, for example, you'd prefer to install +into `/home/me/mystuff/lib`, `/home/me/mystuff/include`, and +`/home/me/mystuff/bin`, you can tell `configure` about that with: + +```console +./configure --prefix=/home/me/mystuff +``` + +Another interesting option is to enable 64-bit integer support for +line and column numbers and the over-all byte index: + +```console +./configure CPPFLAGS=-DXML_LARGE_SIZE +``` + +However, such a modification would be a breaking change to the ABI +and is therefore not recommended for general use — e.g. as part of +a Linux distribution — but rather for builds with special requirements. + +After running the configure script, the `make` command will build +things and `make install` will install things into their proper +location. Have a look at the `Makefile` to learn about additional +`make` options. Note that you need to have write permission into +the directories into which things will be installed. + +If you are interested in building Expat to provide document +information in UTF-16 encoding rather than the default UTF-8, follow +these instructions (after having run `make distclean`). +Please note that we configure with `--without-xmlwf` as xmlwf does not +support this mode of compilation (yet): + +1. Mass-patch `Makefile.am` files to use `libexpatw.la` for a library name: +
+ `find -name Makefile.am -exec sed + -e 's,libexpat\.la,libexpatw.la,' + -e 's,libexpat_la,libexpatw_la,' + -i {} +` + +1. Run `automake` to re-write `Makefile.in` files:
+ `automake` + +1. For UTF-16 output as unsigned short (and version/error strings as char), + run:
+ `./configure CPPFLAGS=-DXML_UNICODE --without-xmlwf`
+ For UTF-16 output as `wchar_t` (incl. version/error strings), run:
+ `./configure CFLAGS="-g -O2 -fshort-wchar" CPPFLAGS=-DXML_UNICODE_WCHAR_T + --without-xmlwf` +
Note: The latter requires libc compiled with `-fshort-wchar`, as well. + +1. Run `make` (which excludes xmlwf). + +1. Run `make install` (again, excludes xmlwf). + +Using `DESTDIR` is supported. It works as follows: + +```console +make install DESTDIR=/path/to/image +``` + +overrides the in-makefile set `DESTDIR`, because variable-setting priority is + +1. commandline +1. in-makefile +1. environment + +Note: This only applies to the Expat library itself, building UTF-16 versions +of xmlwf and the tests is currently not supported. + +When using Expat with a project using autoconf for configuration, you +can use the probing macro in `conftools/expat.m4` to determine how to +include Expat. See the comments at the top of that file for more +information. + +A reference manual is available in the file `doc/reference.html` in this +distribution. diff --git a/src/expat/aclocal.m4 b/src/expat/aclocal.m4 new file mode 100644 index 000000000..3610979ed --- /dev/null +++ b/src/expat/aclocal.m4 @@ -0,0 +1,1157 @@ +# generated automatically by aclocal 1.15.1 -*- Autoconf -*- + +# Copyright (C) 1996-2017 Free Software Foundation, Inc. + +# This file is free software; the Free Software Foundation +# gives unlimited permission to copy and/or distribute it, +# with or without modifications, as long as this notice is preserved. + +# This program is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY, to the extent permitted by law; without +# even the implied warranty of MERCHANTABILITY or FITNESS FOR A +# PARTICULAR PURPOSE. + +m4_ifndef([AC_CONFIG_MACRO_DIRS], [m4_defun([_AM_CONFIG_MACRO_DIRS], [])m4_defun([AC_CONFIG_MACRO_DIRS], [_AM_CONFIG_MACRO_DIRS($@)])]) +m4_ifndef([AC_AUTOCONF_VERSION], + [m4_copy([m4_PACKAGE_VERSION], [AC_AUTOCONF_VERSION])])dnl +m4_if(m4_defn([AC_AUTOCONF_VERSION]), [2.69],, +[m4_warning([this file was generated for autoconf 2.69. +You have another version of autoconf.

Release 2.0.1
+
+ +

Expat is a library, written in C, for parsing XML documents. It's +the underlying XML parser for the open source Mozilla project, Perl's +XML::Parser, Python's xml.parsers.expat, and +other open-source XML parsers.

+ +

This library is the creation of James Clark, who's also given us +groff (an nroff look-alike), Jade (an implementation of ISO's DSSSL +stylesheet language for SGML), XP (a Java XML parser package), XT (a +Java XSL engine). James was also the technical lead on the XML +Working Group at W3C that produced the XML specification.

+ +

This is free software, licensed under the MIT/X Consortium license. You may download it +from the Expat home page. +

+ +

The bulk of this document was originally commissioned as an article +by XML.com. They graciously allowed +Clark Cooper to retain copyright and to distribute it with Expat. +This version has been substantially extended to include documentation +on features which have been added since the original article was +published, and additional information on using the original +interface.

+ +
+

Table of Contents

+ + +
+

Overview

+ +

Expat is a stream-oriented parser. You register callback (or +handler) functions with the parser and then start feeding it the +document. As the parser recognizes parts of the document, it will +call the appropriate handler for that part (if you've registered one.) +The document is fed to the parser in pieces, so you can start parsing +before you have all the document. This also allows you to parse really +huge documents that won't fit into memory.

+ +

Expat can be intimidating due to the many kinds of handlers and +options you can set. But you only need to learn four functions in +order to do 90% of what you'll want to do with it:

+ +
+ +
XML_ParserCreate
+
Create a new parser object.
+ +
XML_SetElementHandler
+
Set handlers for start and end tags.
+ +
XML_SetCharacterDataHandler
+
Set handler for text.
+ +
XML_Parse
+
Pass a buffer full of document to the parser
+
+ +

These functions and others are described in the reference part of this document. The reference +section also describes in detail the parameters passed to the +different types of handlers.

+ +

Let's look at a very simple example program that only uses 3 of the +above functions (it doesn't need to set a character handler.) The +program outline.c prints an +element outline, indenting child elements to distinguish them from the +parent element that contains them. The start handler does all the +work. It prints two indenting spaces for every level of ancestor +elements, then it prints the element and attribute +information. Finally it increments the global Depth +variable.

+ +
+int Depth;
+
+void XMLCALL
+start(void *data, const char *el, const char **attr) {
+  int i;
+
+  for (i = 0; i < Depth; i++)
+    printf("  ");
+
+  printf("%s", el);
+
+  for (i = 0; attr[i]; i += 2) {
+    printf(" %s='%s'", attr[i], attr[i + 1]);
+  }
+
+  printf("\n");
+  Depth++;
+}  /* End of start handler */
+
+ +

The end tag simply does the bookkeeping work of decrementing +Depth.

+
+void XMLCALL
+end(void *data, const char *el) {
+  Depth--;
+}  /* End of end handler */
+
+ +

Note the XMLCALL annotation used for the callbacks. +This is used to ensure that the Expat and the callbacks are using the +same calling convention in case the compiler options used for Expat +itself and the client code are different. Expat tries not to care +what the default calling convention is, though it may require that it +be compiled with a default convention of "cdecl" on some platforms. +For code which uses Expat, however, the calling convention is +specified by the XMLCALL annotation on most platforms; +callbacks should be defined using this annotation.

+ +

The XMLCALL annotation was added in Expat 1.95.7, but +existing working Expat applications don't need to add it (since they +are already using the "cdecl" calling convention, or they wouldn't be +working). The annotation is only needed if the default calling +convention may be something other than "cdecl". To use the annotation +safely with older versions of Expat, you can conditionally define it +after including Expat's header file:

+ +
+#include <expat.h>
+
+#ifndef XMLCALL
+#if defined(_MSC_EXTENSIONS) && !defined(__BEOS__) && !defined(__CYGWIN__)
+#define XMLCALL __cdecl
+#elif defined(__GNUC__)
+#define XMLCALL __attribute__((cdecl))
+#else
+#define XMLCALL
+#endif
+#endif
+
+ +

After creating the parser, the main program just has the job of +shoveling the document to the parser so that it can do its work.

+ +
+

Building and Installing Expat

+ +

The Expat distribution comes as a compressed (with GNU gzip) tar +file. You may download the latest version from Source Forge. After +unpacking this, cd into the directory. Then follow either the Win32 +directions or Unix directions below.

+ +

Building under Win32

+ +

If you're using the GNU compiler under cygwin, follow the Unix +directions in the next section. Otherwise if you have Microsoft's +Developer Studio installed, then from Windows Explorer double-click on +"expat.vcxproj" in the lib directory and build and install in the usual +manner.

+ +

Alternatively, you may download the Win32 binary package that +contains the "expat.h" include file and a pre-built DLL.

+ +

Building under Unix (or GNU)

+ +

First you'll need to run the configure shell script in order to +configure the Makefiles and headers for your system.

+ +

If you're happy with all the defaults that configure picks for you, +and you have permission on your system to install into /usr/local, you +can install Expat with this sequence of commands:

+ +
+./configure
+make
+make install
+
+ +

There are some options that you can provide to this script, but the +only one we'll mention here is the --prefix option. You +can find out all the options available by running configure with just +the --help option.

+ +

By default, the configure script sets things up so that the library +gets installed in /usr/local/lib and the associated +header file in /usr/local/include. But if you were to +give the option, --prefix=/home/me/mystuff, then the +library and header would get installed in +/home/me/mystuff/lib and +/home/me/mystuff/include respectively.

+ +

Configuring Expat Using the Pre-Processor

+ +

Expat's feature set can be configured using a small number of +pre-processor definitions. The definition of this symbols does not +affect the set of entry points for Expat, only the behavior of the API +and the definition of character types in the case of +XML_UNICODE_WCHAR_T. The symbols are:

+ +
+
XML_DTD
+
Include support for using and reporting DTD-based content. If +this is defined, default attribute values from an external DTD subset +are reported and attribute value normalization occurs based on the +type of attributes defined in the external subset. Without +this, Expat has a smaller memory footprint and can be faster, but will +not load external entities or process conditional sections. This does +not affect the set of functions available in the API.
+ +
XML_NS
+
When defined, support for the Namespaces in XML +specification is included.
+ +
XML_UNICODE
+
When defined, character data reported to the application is +encoded in UTF-16 using wide characters of the type +XML_Char. This is implied if +XML_UNICODE_WCHAR_T is defined.
+ +
XML_UNICODE_WCHAR_T
+
If defined, causes the XML_Char character type to be +defined using the wchar_t type; otherwise, unsigned +short is used. Defining this implies +XML_UNICODE.
+ +
XML_LARGE_SIZE
+
If defined, causes the XML_Size and XML_Index +integer types to be at least 64 bits in size. This is intended to support +processing of very large input streams, where the return values of +XML_GetCurrentByteIndex, +XML_GetCurrentLineNumber and +XML_GetCurrentColumnNumber +could overflow. It may not be supported by all compilers, and is turned +off by default.
+ +
XML_CONTEXT_BYTES
+
The number of input bytes of markup context which the parser will +ensure are available for reporting via XML_GetInputContext. This is +normally set to 1024, and must be set to a positive integer. If this +is not defined, the input context will not be available and XML_GetInputContext will +always report NULL. Without this, Expat has a smaller memory +footprint and can be faster.
+ +
XML_STATIC
+
On Windows, this should be set if Expat is going to be linked +statically with the code that calls it; this is required to get all +the right MSVC magic annotations correct. This is ignored on other +platforms.
+ +
XML_ATTR_INFO
+
If defined, makes the additional function XML_GetAttributeInfo available +for reporting attribute byte offsets.
+
+ +
+

Using Expat

+ +

Compiling and Linking Against Expat

+ +

Unless you installed Expat in a location not expected by your +compiler and linker, all you have to do to use Expat in your programs +is to include the Expat header (#include <expat.h>) +in your files that make calls to it and to tell the linker that it +needs to link against the Expat library. On Unix systems, this would +usually be done with the -lexpat argument. Otherwise, +you'll need to tell the compiler where to look for the Expat header +and the linker where to find the Expat library. You may also need to +take steps to tell the operating system where to find this library at +run time.

+ +

On a Unix-based system, here's what a Makefile might look like when +Expat is installed in a standard location:

+ +
+CC=cc
+LDFLAGS=
+LIBS= -lexpat
+xmlapp: xmlapp.o
+        $(CC) $(LDFLAGS) -o xmlapp xmlapp.o $(LIBS)
+
+ +

If you installed Expat in, say, /home/me/mystuff, then +the Makefile would look like this:

+ +
+CC=cc
+CFLAGS= -I/home/me/mystuff/include
+LDFLAGS=
+LIBS= -L/home/me/mystuff/lib -lexpat
+xmlapp: xmlapp.o
+        $(CC) $(LDFLAGS) -o xmlapp xmlapp.o $(LIBS)
+
+ +

You'd also have to set the environment variable +LD_LIBRARY_PATH to /home/me/mystuff/lib (or +to ${LD_LIBRARY_PATH}:/home/me/mystuff/lib if +LD_LIBRARY_PATH already has some directories in it) in order to run +your application.

+ +

Expat Basics

+ +

As we saw in the example in the overview, the first step in parsing +an XML document with Expat is to create a parser object. There are three functions in the Expat API for creating a +parser object. However, only two of these (XML_ParserCreate and XML_ParserCreateNS) can be used for +constructing a parser for a top-level document. The object returned +by these functions is an opaque pointer (i.e. "expat.h" declares it as +void *) to data with further internal structure. In order to free the +memory associated with this object you must call XML_ParserFree. Note that if you have +provided any user data that gets stored in the +parser, then your application is responsible for freeing it prior to +calling XML_ParserFree.

+ +

The objects returned by the parser creation functions are good for +parsing only one XML document or external parsed entity. If your +application needs to parse many XML documents, then it needs to create +a parser object for each one. The best way to deal with this is to +create a higher level object that contains all the default +initialization you want for your parser objects.

+ +

Walking through a document hierarchy with a stream oriented parser +will require a good stack mechanism in order to keep track of current +context. For instance, to answer the simple question, "What element +does this text belong to?" requires a stack, since the parser may have +descended into other elements that are children of the current one and +has encountered this text on the way out.

+ +

The things you're likely to want to keep on a stack are the +currently opened element and it's attributes. You push this +information onto the stack in the start handler and you pop it off in +the end handler.

+ +

For some tasks, it is sufficient to just keep information on what +the depth of the stack is (or would be if you had one.) The outline +program shown above presents one example. Another such task would be +skipping over a complete element. When you see the start tag for the +element you want to skip, you set a skip flag and record the depth at +which the element started. When the end tag handler encounters the +same depth, the skipped element has ended and the flag may be +cleared. If you follow the convention that the root element starts at +1, then you can use the same variable for skip flag and skip +depth.

+ +
+void
+init_info(Parseinfo *info) {
+  info->skip = 0;
+  info->depth = 1;
+  /* Other initializations here */
+}  /* End of init_info */
+
+void XMLCALL
+rawstart(void *data, const char *el, const char **attr) {
+  Parseinfo *inf = (Parseinfo *) data;
+
+  if (! inf->skip) {
+    if (should_skip(inf, el, attr)) {
+      inf->skip = inf->depth;
+    }
+    else
+      start(inf, el, attr);     /* This does rest of start handling */
+  }
+
+  inf->depth++;
+}  /* End of rawstart */
+
+void XMLCALL
+rawend(void *data, const char *el) {
+  Parseinfo *inf = (Parseinfo *) data;
+
+  inf->depth--;
+
+  if (! inf->skip)
+    end(inf, el);              /* This does rest of end handling */
+
+  if (inf->skip == inf->depth)
+    inf->skip = 0;
+}  /* End rawend */
+
+ +

Notice in the above example the difference in how depth is +manipulated in the start and end handlers. The end tag handler should +be the mirror image of the start tag handler. This is necessary to +properly model containment. Since, in the start tag handler, we +incremented depth after the main body of start tag code, then +in the end handler, we need to manipulate it before the main +body. If we'd decided to increment it first thing in the start +handler, then we'd have had to decrement it last thing in the end +handler.

+ +

Communicating between handlers

+ +

In order to be able to pass information between different handlers +without using globals, you'll need to define a data structure to hold +the shared variables. You can then tell Expat (with the XML_SetUserData function) to pass a +pointer to this structure to the handlers. This is the first +argument received by most handlers. In the reference section, an argument to a callback function is named +userData and have type void * if the user +data is passed; it will have the type XML_Parser if the +parser itself is passed. When the parser is passed, the user data may +be retrieved using XML_GetUserData.

+ +

One common case where multiple calls to a single handler may need +to communicate using an application data structure is the case when +content passed to the character data handler (set by XML_SetCharacterDataHandler) needs to be accumulated. A +common first-time mistake with any of the event-oriented interfaces to +an XML parser is to expect all the text contained in an element to be +reported by a single call to the character data handler. Expat, like +many other XML parsers, reports such data as a sequence of calls; +there's no way to know when the end of the sequence is reached until a +different callback is made. A buffer referenced by the user data +structure proves both an effective and convenient place to accumulate +character data.

+ + + + +

XML Version

+ +

Expat is an XML 1.0 parser, and as such never complains based on +the value of the version pseudo-attribute in the XML +declaration, if present.

+ +

If an application needs to check the version number (to support +alternate processing), it should use the XML_SetXmlDeclHandler function to +set a handler that uses the information in the XML declaration to +determine what to do. This example shows how to check that only a +version number of "1.0" is accepted:

+ +
+static int wrong_version;
+static XML_Parser parser;
+
+static void XMLCALL
+xmldecl_handler(void            *userData,
+                const XML_Char  *version,
+                const XML_Char  *encoding,
+                int              standalone)
+{
+  static const XML_Char Version_1_0[] = {'1', '.', '0', 0};
+
+  int i;
+
+  for (i = 0; i < (sizeof(Version_1_0) / sizeof(Version_1_0[0])); ++i) {
+    if (version[i] != Version_1_0[i]) {
+      wrong_version = 1;
+      /* also clear all other handlers: */
+      XML_SetCharacterDataHandler(parser, NULL);
+      ...
+      return;
+    }
+  }
+  ...
+}
+
+ +

Namespace Processing

+ +

When the parser is created using the XML_ParserCreateNS, function, Expat +performs namespace processing. Under namespace processing, Expat +consumes xmlns and xmlns:... attributes, +which declare namespaces for the scope of the element in which they +occur. This means that your start handler will not see these +attributes. Your application can still be informed of these +declarations by setting namespace declaration handlers with XML_SetNamespaceDeclHandler.

+ +

Element type and attribute names that belong to a given namespace +are passed to the appropriate handler in expanded form. By default +this expanded form is a concatenation of the namespace URI, the +separator character (which is the 2nd argument to XML_ParserCreateNS), and the local +name (i.e. the part after the colon). Names with undeclared prefixes +are not well-formed when namespace processing is enabled, and will +trigger an error. Unprefixed attribute names are never expanded, +and unprefixed element names are only expanded when they are in the +scope of a default namespace.

+ +

However if XML_SetReturnNSTriplet has been called with a non-zero +do_nst parameter, then the expanded form for names with +an explicit prefix is a concatenation of: URI, separator, local name, +separator, prefix.

+ +

You can set handlers for the start of a namespace declaration and +for the end of a scope of a declaration with the XML_SetNamespaceDeclHandler +function. The StartNamespaceDeclHandler is called prior to the start +tag handler and the EndNamespaceDeclHandler is called after the +corresponding end tag that ends the namespace's scope. The namespace +start handler gets passed the prefix and URI for the namespace. For a +default namespace declaration (xmlns='...'), the prefix will be null. +The URI will be null for the case where the default namespace is being +unset. The namespace end handler just gets the prefix for the closing +scope.

+ +

These handlers are called for each declaration. So if, for +instance, a start tag had three namespace declarations, then the +StartNamespaceDeclHandler would be called three times before the start +tag handler is called, once for each declaration.

+ +

Character Encodings

+ +

While XML is based on Unicode, and every XML processor is required +to recognized UTF-8 and UTF-16 (1 and 2 byte encodings of Unicode), +other encodings may be declared in XML documents or entities. For the +main document, an XML declaration may contain an encoding +declaration:

+
+<?xml version="1.0" encoding="ISO-8859-2"?>
+
+ +

External parsed entities may begin with a text declaration, which +looks like an XML declaration with just an encoding declaration:

+
+<?xml encoding="Big5"?>
+
+ +

With Expat, you may also specify an encoding at the time of +creating a parser. This is useful when the encoding information may +come from a source outside the document itself (like a higher level +protocol.)

+ +

There are four built-in encodings +in Expat:

+
    +
  • UTF-8
    • +
  • UTF-16
    • +
  • ISO-8859-1
    • +
  • US-ASCII
    • +
+ +

Anything else discovered in an encoding declaration or in the +protocol encoding specified in the parser constructor, triggers a call +to the UnknownEncodingHandler. This handler gets passed +the encoding name and a pointer to an XML_Encoding data +structure. Your handler must fill in this structure and return +XML_STATUS_OK if it knows how to deal with the +encoding. Otherwise the handler should return +XML_STATUS_ERROR. The handler also gets passed a pointer +to an optional application data structure that you may indicate when +you set the handler.

+ +

Expat places restrictions on character encodings that it can +support by filling in the XML_Encoding structure. +include file:

+
    +
  1. Every ASCII character that can appear in a well-formed XML document +must be represented by a single byte, and that byte must correspond to +it's ASCII encoding (except for the characters $@\^'{}~)
    2. +
  2. Characters must be encoded in 4 bytes or less.
    3. +
  3. All characters encoded must have Unicode scalar values less than or +equal to 65535 (0xFFFF)This does not apply to the built-in support +for UTF-16 and UTF-8
    4. +
  4. No character may be encoded by more that one distinct sequence of +bytes
    5. +
+ +

XML_Encoding contains an array of integers that +correspond to the 1st byte of an encoding sequence. If the value in +the array for a byte is zero or positive, then the byte is a single +byte encoding that encodes the Unicode scalar value contained in the +array. A -1 in this array indicates a malformed byte. If the value is +-2, -3, or -4, then the byte is the beginning of a 2, 3, or 4 byte +sequence respectively. Multi-byte sequences are sent to the convert +function pointed at in the XML_Encoding structure. This +function should return the Unicode scalar value for the sequence or -1 +if the sequence is malformed.

+ +

One pitfall that novice Expat users are likely to fall into is that +although Expat may accept input in various encodings, the strings that +it passes to the handlers are always encoded in UTF-8 or UTF-16 +(depending on how Expat was compiled). Your application is responsible +for any translation of these strings into other encodings.

+ +

Handling External Entity References

+ +

Expat does not read or parse external entities directly. Note that +any external DTD is a special case of an external entity. If you've +set no ExternalEntityRefHandler, then external entity +references are silently ignored. Otherwise, it calls your handler with +the information needed to read and parse the external entity.

+ +

Your handler isn't actually responsible for parsing the entity, but +it is responsible for creating a subsidiary parser with XML_ExternalEntityParserCreate that will do the job. This +returns an instance of XML_Parser that has handlers and +other data structures initialized from the parent parser. You may then +use XML_Parse or XML_ParseBuffer calls against this +parser. Since external entities my refer to other external entities, +your handler should be prepared to be called recursively.

+ +

Parsing DTDs

+ +

In order to parse parameter entities, before starting the parse, +you must call XML_SetParamEntityParsing with one of the following +arguments:

+
+
XML_PARAM_ENTITY_PARSING_NEVER
+
Don't parse parameter entities or the external subset
+
XML_PARAM_ENTITY_PARSING_UNLESS_STANDALONE
+
Parse parameter entities and the external subset unless +standalone was set to "yes" in the XML declaration.
+
XML_PARAM_ENTITY_PARSING_ALWAYS
+
Always parse parameter entities and the external subset
+
+ +

In order to read an external DTD, you also have to set an external +entity reference handler as described above.

+ +

Temporarily Stopping Parsing

+ +

Expat 1.95.8 introduces a new feature: its now possible to stop +parsing temporarily from within a handler function, even if more data +has already been passed into the parser. Applications for this +include

+ +
    +
  • Supporting the XInclude specification.
    • + +
  • Delaying further processing until additional information is + available from some other source.
    • + +
  • Adjusting processor load as task priorities shift within an + application.
    • + +
  • Stopping parsing completely (simply free or reset the parser + instead of resuming in the outer parsing loop). This can be useful + if an application-domain error is found in the XML being parsed or if + the result of the parse is determined not to be useful after + all.
    • +
+ +

To take advantage of this feature, the main parsing loop of an +application needs to support this specifically. It cannot be +supported with a parsing loop compatible with Expat 1.95.7 or +earlier (though existing loops will continue to work without +supporting the stop/resume feature).

+ +

An application that uses this feature for a single parser will have +the rough structure (in pseudo-code):

+ +
+fd = open_input()
+p = create_parser()
+
+if parse_xml(p, fd) {
+  /* suspended */
+
+  int suspended = 1;
+
+  while (suspended) {
+    do_something_else()
+    if ready_to_resume() {
+      suspended = continue_parsing(p, fd);
+    }
+  }
+}
+
+ +

An application that may resume any of several parsers based on +input (either from the XML being parsed or some other source) will +certainly have more interesting control structures.

+ +

This C function could be used for the parse_xml +function mentioned in the pseudo-code above:

+ +
+#define BUFF_SIZE 10240
+
+/* Parse a document from the open file descriptor 'fd' until the parse
+   is complete (the document has been completely parsed, or there's
+   been an error), or the parse is stopped.  Return non-zero when
+   the parse is merely suspended.
+*/
+int
+parse_xml(XML_Parser p, int fd)
+{
+  for (;;) {
+    int last_chunk;
+    int bytes_read;
+    enum XML_Status status;
+
+    void *buff = XML_GetBuffer(p, BUFF_SIZE);
+    if (buff == NULL) {
+      /* handle error... */
+      return 0;
+    }
+    bytes_read = read(fd, buff, BUFF_SIZE);
+    if (bytes_read < 0) {
+      /* handle error... */
+      return 0;
+    }
+    status = XML_ParseBuffer(p, bytes_read, bytes_read == 0);
+    switch (status) {
+      case XML_STATUS_ERROR:
+        /* handle error... */
+        return 0;
+      case XML_STATUS_SUSPENDED:
+        return 1;
+    }
+    if (bytes_read == 0)
+      return 0;
+  }
+}
+
+ +

The corresponding continue_parsing function is +somewhat simpler, since it only need deal with the return code from +XML_ResumeParser; it can +delegate the input handling to the parse_xml +function:

+ +
+/* Continue parsing a document which had been suspended.  The 'p' and
+   'fd' arguments are the same as passed to parse_xml().  Return
+   non-zero when the parse is suspended.
+*/
+int
+continue_parsing(XML_Parser p, int fd)
+{
+  enum XML_Status status = XML_ResumeParser(p);
+  switch (status) {
+    case XML_STATUS_ERROR:
+      /* handle error... */
+      return 0;
+    case XML_ERROR_NOT_SUSPENDED:
+      /* handle error... */
+      return 0;.
+    case XML_STATUS_SUSPENDED:
+      return 1;
+  }
+  return parse_xml(p, fd);
+}
+
+ +

Now that we've seen what a mess the top-level parsing loop can +become, what have we gained? Very simply, we can now use the XML_StopParser function to stop +parsing, without having to go to great lengths to avoid additional +processing that we're expecting to ignore. As a bonus, we get to stop +parsing temporarily, and come back to it when we're +ready.

+ +

To stop parsing from a handler function, use the XML_StopParser function. This function +takes two arguments; the parser being stopped and a flag indicating +whether the parse can be resumed in the future.

+ + + + +

Parser Creation

+ +
+XML_Parser XMLCALL
+XML_ParserCreate(const XML_Char *encoding);
+
+
+Construct a new parser. If encoding is non-null, it specifies a +character encoding to use for the document. This overrides the document +encoding declaration. There are four built-in encodings: +
    +
  • US-ASCII
    • +
  • UTF-8
    • +
  • UTF-16
    • +
  • ISO-8859-1
    • +
+Any other value will invoke a call to the UnknownEncodingHandler. +
+ +
+XML_Parser XMLCALL
+XML_ParserCreateNS(const XML_Char *encoding,
+                   XML_Char sep);
+
+
+Constructs a new parser that has namespace processing in effect. Namespace +expanded element names and attribute names are returned as a concatenation +of the namespace URI, sep, and the local part of the name. This +means that you should pick a character for sep that can't be part +of an URI. Since Expat does not check namespace URIs for conformance, the +only safe choice for a namespace separator is a character that is illegal +in XML. For instance, '\xFF' is not legal in UTF-8, and +'\xFFFF' is not legal in UTF-16. There is a special case when +sep is the null character '\0': the namespace URI and +the local part will be concatenated without any separator - this is intended +to support RDF processors. It is a programming error to use the null separator +with namespace triplets.
+ +
+XML_Parser XMLCALL
+XML_ParserCreate_MM(const XML_Char *encoding,
+                    const XML_Memory_Handling_Suite *ms,
+		    const XML_Char *sep);
+
+
+typedef struct {
+  void *(XMLCALL *malloc_fcn)(size_t size);
+  void *(XMLCALL *realloc_fcn)(void *ptr, size_t size);
+  void (XMLCALL *free_fcn)(void *ptr);
+} XML_Memory_Handling_Suite;
+
+
+

Construct a new parser using the suite of memory handling functions +specified in ms. If ms is NULL, then use the +standard set of memory management functions. If sep is +non NULL, then namespace processing is enabled in the created parser +and the character pointed at by sep is used as the separator between +the namespace URI and the local part of the name.

+
+ +
+XML_Parser XMLCALL
+XML_ExternalEntityParserCreate(XML_Parser p,
+                               const XML_Char *context,
+                               const XML_Char *encoding);
+
+
+Construct a new XML_Parser object for parsing an external +general entity. Context is the context argument passed in a call to a +ExternalEntityRefHandler. Other state information such as handlers, +user data, namespace processing is inherited from the parser passed as +the 1st argument. So you shouldn't need to call any of the behavior +changing functions on this parser (unless you want it to act +differently than the parent parser). +
+ +
+void XMLCALL
+XML_ParserFree(XML_Parser p);
+
+
+Free memory used by the parser. Your application is responsible for +freeing any memory associated with user data. +
+ +
+XML_Bool XMLCALL
+XML_ParserReset(XML_Parser p,
+                const XML_Char *encoding);
+
+
+Clean up the memory structures maintained by the parser so that it may +be used again. After this has been called, parser is +ready to start parsing a new document. All handlers are cleared from +the parser, except for the unknownEncodingHandler. The parser's external +state is re-initialized except for the values of ns and ns_triplets. +This function may not be used on a parser created using XML_ExternalEntityParserCreate; it will return XML_FALSE in that case. Returns +XML_TRUE on success. Your application is responsible for +dealing with any memory associated with user data. +
+ +

Parsing

+ +

To state the obvious: the three parsing functions XML_Parse, +XML_ParseBuffer and +XML_GetBuffer must not be called from within a handler +unless they operate on a separate parser instance, that is, one that +did not call the handler. For example, it is OK to call the parsing +functions from within an XML_ExternalEntityRefHandler, +if they apply to the parser created by +XML_ExternalEntityParserCreate.

+ +

Note: the len argument passed to these functions +should be considerably less than the maximum value for an integer, +as it could create an integer overflow situation if the added +lengths of a buffer and the unprocessed portion of the previous buffer +exceed the maximum integer value. Input data at the end of a buffer +will remain unprocessed if it is part of an XML token for which the +end is not part of that buffer.

+ +
+enum XML_Status XMLCALL
+XML_Parse(XML_Parser p,
+          const char *s,
+          int len,
+          int isFinal);
+
+
+enum XML_Status {
+  XML_STATUS_ERROR = 0,
+  XML_STATUS_OK = 1
+};
+
+
+Parse some more of the document. The string s is a buffer +containing part (or perhaps all) of the document. The number of bytes of s +that are part of the document is indicated by len. This means +that s doesn't have to be null terminated. It also means that +if len is larger than the number of bytes in the block of +memory that s points at, then a memory fault is likely. The +isFinal parameter informs the parser that this is the last +piece of the document. Frequently, the last piece is empty (i.e. +len is zero.) +If a parse error occurred, it returns XML_STATUS_ERROR. +Otherwise it returns XML_STATUS_OK value. +
+ +
+enum XML_Status XMLCALL
+XML_ParseBuffer(XML_Parser p,
+                int len,
+                int isFinal);
+
+
+This is just like XML_Parse, +except in this case Expat provides the buffer. By obtaining the +buffer from Expat with the XML_GetBuffer function, the application can avoid double +copying of the input. +
+ +
+void * XMLCALL
+XML_GetBuffer(XML_Parser p,
+              int len);
+
+
+Obtain a buffer of size len to read a piece of the document +into. A NULL value is returned if Expat can't allocate enough memory for +this buffer. This has to be called prior to every call to +XML_ParseBuffer. A +typical use would look like this: + +
+for (;;) {
+  int bytes_read;
+  void *buff = XML_GetBuffer(p, BUFF_SIZE);
+  if (buff == NULL) {
+    /* handle error */
+  }
+
+  bytes_read = read(docfd, buff, BUFF_SIZE);
+  if (bytes_read < 0) {
+    /* handle error */
+  }
+
+  if (! XML_ParseBuffer(p, bytes_read, bytes_read == 0)) {
+    /* handle parse error */
+  }
+
+  if (bytes_read == 0)
+    break;
+}
+
+
+ +
+enum XML_Status XMLCALL
+XML_StopParser(XML_Parser p,
+               XML_Bool resumable);
+
+
+ +

Stops parsing, causing XML_Parse or XML_ParseBuffer to return. Must be called from within a +call-back handler, except when aborting (when resumable +is XML_FALSE) an already suspended parser. Some +call-backs may still follow because they would otherwise get +lost, including +

    +
  • the end element handler for empty elements when stopped in the + start element handler,
    • +
  • the end namespace declaration handler when stopped in the end + element handler,
    • +
  • the character data handler when stopped in the character data handler + while making multiple call-backs on a contiguous chunk of characters,
    • +
+and possibly others.

+ +

This can be called from most handlers, including DTD related +call-backs, except when parsing an external parameter entity and +resumable is XML_TRUE. Returns +XML_STATUS_OK when successful, +XML_STATUS_ERROR otherwise. The possible error codes +are:

+
+
XML_ERROR_SUSPENDED
+
when suspending an already suspended parser.
+
XML_ERROR_FINISHED
+
when the parser has already finished.
+
XML_ERROR_SUSPEND_PE
+
when suspending while parsing an external PE.
+
+ +

Since the stop/resume feature requires application support in the +outer parsing loop, it is an error to call this function for a parser +not being handled appropriately; see Temporarily Stopping Parsing for more information.

+ +

When resumable is XML_TRUE then parsing +is suspended, that is, XML_Parse and XML_ParseBuffer return XML_STATUS_SUSPENDED. +Otherwise, parsing is aborted, that is, XML_Parse and XML_ParseBuffer return +XML_STATUS_ERROR with error code +XML_ERROR_ABORTED.

+ +

Note: +This will be applied to the current parser instance only, that is, if +there is a parent parser then it will continue parsing when the +external entity reference handler returns. It is up to the +implementation of that handler to call XML_StopParser on the parent parser +(recursively), if one wants to stop parsing altogether.

+ +

When suspended, parsing can be resumed by calling XML_ResumeParser.

+ +

New in Expat 1.95.8.

+
+ +
+enum XML_Status XMLCALL
+XML_ResumeParser(XML_Parser p);
+
+
+

Resumes parsing after it has been suspended with XML_StopParser. Must not be called from +within a handler call-back. Returns same status codes as XML_Parse or XML_ParseBuffer. An additional error +code, XML_ERROR_NOT_SUSPENDED, will be returned if the +parser was not currently suspended.

+ +

Note: +This must be called on the most deeply nested child parser instance +first, and on its parent parser only after the child parser has +finished, to be applied recursively until the document entity's parser +is restarted. That is, the parent parser will not resume by itself +and it is up to the application to call XML_ResumeParser on it at the +appropriate moment.

+ + +

Handler Setting

+ +

Although handlers are typically set prior to parsing and left alone, an +application may choose to set or change the handler for a parsing event +while the parse is in progress. For instance, your application may choose +to ignore all text not descended from a para element. One +way it could do this is to set the character handler when a para start tag +is seen, and unset it for the corresponding end tag.

+ +

A handler may be unset by providing a NULL pointer to the +appropriate handler setter. None of the handler setting functions have +a return value.

+ +

Your handlers will be receiving strings in arrays of type +XML_Char. This type is conditionally defined in expat.h as +either char, wchar_t or unsigned short. +The former implies UTF-8 encoding, the latter two imply UTF-16 encoding. +Note that you'll receive them in this form independent of the original +encoding of the document.

+ +
+

+                                   const XML_Char **atts);
+
+

Set handler for start (and empty) tags. Attributes are passed to the start +handler as a pointer to a vector of char pointers. Each attribute seen in +a start (or empty) tag occupies 2 consecutive places in this vector: the +attribute name followed by the attribute value. These pairs are terminated +by a null pointer.

+

Note that an empty tag generates a call to both start and end handlers +(in that order).

+
+

Set a text handler. The string your handler receives +is NOT nul-terminated. You have to use the length argument +to deal with the end of the string. A single block of contiguous text +free of markup may still result in a sequence of calls to this handler. +In other words, if you're searching for a pattern in the text, it may +be split across calls to this handler. Note: Setting this handler to NULL +may NOT immediately terminate call-backs if the parser is currently +processing such a single block of contiguous markup-free text, as the parser +will continue calling back until the end of the block is reached.

+
+ +

Sets a handler for any characters in the document which wouldn't +otherwise be handled. This includes both data for which no handlers +can be set (like some kinds of DTD declarations) and data which could +be reported but which currently has no handler set. The characters +are passed exactly as they were present in the XML document except +that they will be encoded in UTF-8 or UTF-16. Line boundaries are not +normalized. Note that a byte order mark character is not passed to the +default handler. There are no guarantees about how characters are +divided between calls to the default handler: for example, a comment +might be split between multiple calls. Setting the handler with +this call has the side effect of turning off expansion of references +to internally defined general entities. Instead these references are +passed to the default handler.

The context parameter specifies the parsing context in +the format expected by the context argument to XML_ExternalEntityParserCreate. code is +valid only until the handler returns, so if the referenced entity is +to be parsed later, it must be copied. context is NULL +only when the entity is a parameter entity, which is how one can +differentiate between general and parameter entities.

+ +

The base parameter is the base to use for relative +system identifiers. It is set by XML_SetBase and may be NULL. The +publicId parameter is the public id given in the entity +declaration and may be NULL. systemId is the system +identifier specified in the entity declaration and is never NULL.

+ +

There are a couple of ways in which this handler differs from +others. First, this handler returns a status indicator (an +integer). XML_STATUS_OK should be returned for successful +handling of the external entity reference. Returning +XML_STATUS_ERROR indicates failure, and causes the +calling parser to return an +XML_ERROR_EXTERNAL_ENTITY_HANDLING error.

+ +

Second, instead of having the user data as its first argument, it +receives the parser that encountered the entity reference. This, along +with the context parameter, may be used as arguments to a call to +XML_ExternalEntityParserCreate. Using the returned +parser, the body of the external entity can be recursively parsed.

+ +

Since this handler may be called recursively, it should not be saving +information into global or static variables.

+
+ +
+void XMLCALL
+XML_SetExternalEntityRefHandlerArg(XML_Parser p,
+                                   void *arg)
+
+
+

Set the argument passed to the ExternalEntityRefHandler. If +arg is not NULL, it is the new value passed to the +handler set using XML_SetExternalEntityRefHandler; if arg is +NULL, the argument passed to the handler function will be the parser +object itself.

+ +

Note: +The type of arg and the type of the first argument to the +ExternalEntityRefHandler do not match. This function takes a +void * to be passed to the handler, while the handler +accepts an XML_Parser. This is a historical accident, +but will not be corrected before Expat 2.0 (at the earliest) to avoid +causing compiler warnings for code that's known to work with this +API. It is the responsibility of the application code to know the +actual type of the argument passed to the handler and to manage it +properly.

+                                    int is_parameter_entity);
+
+

Set a skipped entity handler. This is called in two situations:

+
    +
  1. An entity reference is encountered for which no declaration + has been read and this is not an error.
    2. +
  2. An internal entity reference is read, but not expanded, because + XML_SetDefaultHandler + has been called.
    3. +
+

The is_parameter_entity argument will be non-zero for +a parameter entity and zero for a general entity.

Note: skipped +parameter entities in declarations and skipped general entities in +attribute values cannot be reported, because the event would be out of +sync with the reporting of the declarations or attribute values

+  void *data;
+  int (XMLCALL *convert)(void *data, const char *s);
+  void (XMLCALL *release)(void *data);
+} XML_Encoding;
+
+

Set a handler to deal with encodings other than the built in set. This should be done before +XML_Parse or XML_ParseBuffer have been called on the +given parser.

If the handler knows how to deal with an encoding +with the given name, it should fill in the info data +structure and return XML_STATUS_OK. Otherwise it +should return XML_STATUS_ERROR. The handler will be called +at most once per parsed (external) entity. The optional application +data pointer encodingHandlerData will be passed back to +the handler.

+ +

The map array contains information for every possible leading +byte in a byte sequence. If the corresponding value is >= 0, then it's +a single byte sequence and the byte encodes that Unicode value. If the +value is -1, then that byte is invalid as the initial byte in a sequence. +If the value is -n, where n is an integer > 1, then n is the number of +bytes in the sequence and the actual conversion is accomplished by a +call to the function pointed at by convert. This function may return -1 +if the sequence itself is invalid. The convert pointer may be null if +there are only single byte codes. The data parameter passed to the convert +function is the data pointer from XML_Encoding. The +string s is NOT nul-terminated and points at the sequence of +bytes to be converted.

+ +

The function pointed at by release is called by the +parser when it is finished with the encoding. It may be NULL.

Set a handler to be called when a namespace is declared. Namespace +declarations occur inside start tags. But the namespace declaration start +handler is called before the start tag handler for each namespace declared +in that start tag.

+                              int             standalone);
+
+

Sets a handler that is called for XML declarations and also for +text declarations discovered in external entities. The way to +distinguish is that the version parameter will be NULL +for text declarations. The encoding parameter may be NULL +for an XML declaration. The standalone argument will +contain -1, 0, or 1 indicating respectively that there was no +standalone parameter in the declaration, that it was given as no, or +that it was given as yes.

+                                       int            has_internal_subset);
+
+

Set a handler that is called at the start of a DOCTYPE declaration, +before any external or internal subset is parsed. Both sysid +and pubid may be NULL. The has_internal_subset +will be non-zero if the DOCTYPE declaration has an internal subset.

+  XML_Content *			children;
+};
+
+

Sets a handler for element declarations in a DTD. The handler gets +called with the name of the element in the declaration and a pointer +to a structure that contains the element model. It is the +application's responsibility to free this data structure using +XML_FreeContentModel.

+ +

The model argument is the root of a tree of +XML_Content nodes. If type equals +XML_CTYPE_EMPTY or XML_CTYPE_ANY, then +quant will be XML_CQUANT_NONE, and the other +fields will be zero or NULL. If type is +XML_CTYPE_MIXED, then quant will be +XML_CQUANT_NONE or XML_CQUANT_REP and +numchildren will contain the number of elements that are +allowed to be mixed in and children points to an array of +XML_Content structures that will all have type +XML_CTYPE_NAME with no quantification. Only the root node can be type +XML_CTYPE_EMPTY, XML_CTYPE_ANY, or +XML_CTYPE_MIXED.

+ +

For type XML_CTYPE_NAME, the name field +points to the name and the numchildren and +children fields will be zero and NULL. The +quant field will indicate any quantifiers placed on the +name.

+ +

Types XML_CTYPE_CHOICE and XML_CTYPE_SEQ +indicate a choice or sequence respectively. The +numchildren field indicates how many nodes in the choice +or sequence and children points to the nodes.

+
+

Set a handler for attlist declarations in the DTD. This handler is +called for each attribute. So a single attlist declaration +with multiple attributes declared will generate multiple calls to this +handler. The elname parameter returns the name of the +element for which the attribute is being declared. The attribute name +is in the attname parameter. The attribute type is in the +att_type parameter. It is the string representing the +type in the declaration with whitespace removed.

+ +

The dflt parameter holds the default value. It will be +NULL in the case of "#IMPLIED" or "#REQUIRED" attributes. You can +distinguish these two cases by checking the isrequired +parameter, which will be true in the case of "#REQUIRED" attributes. +Attributes which are "#FIXED" will have also have a true +isrequired, but they will have the non-NULL fixed value +in the dflt parameter.

+
+

Sets a handler that will be called for all entity declarations. +The is_parameter_entity argument will be non-zero in the +case of parameter entities and zero otherwise.

+ +

For internal entities (<!ENTITY foo "bar">), +value will be non-NULL and systemId, +publicId, and notationName will all be NULL. +The value string is not NULL terminated; the length is +provided in the value_length parameter. Do not use +value_length to test for internal entities, since it is +legal to have zero-length values. Instead check for whether or not +value is NULL.

The notationName +argument will have a non-NULL value only for unparsed entity +declarations.

Set a handler that receives declarations of unparsed entities. These +are entity declarations that have a notation (NDATA) field:

+<!ENTITY logo SYSTEM "images/logo.gif" NDATA gif>
+
+

This handler is obsolete and is provided for backwards +compatibility. Use instead XML_SetEntityDeclHandler.

+
+
+typedef int 
+(XMLCALL *XML_NotStandaloneHandler)(void *userData);
+
+

Set a handler that is called if the document is not "standalone". +This happens when there is an external subset or a reference to a +parameter entity, but does not have standalone set to "yes" in an XML +declaration. If this handler returns XML_STATUS_ERROR, +then the parser will throw an XML_ERROR_NOT_STANDALONE +error.

+
+ +

Parse position and error reporting functions

+ +

These are the functions you'll want to call when the parse +functions return XML_STATUS_ERROR (a parse error has +occurred), although the position reporting functions are useful outside +of errors. The position reported is the byte position (in the original +document or entity encoding) of the first of the sequence of +characters that generated the current event (or the error that caused +the parse functions to return XML_STATUS_ERROR.) The +exceptions are callbacks trigged by declarations in the document +prologue, in which case they exact position reported is somewhere in the +relevant markup, but not necessarily as meaningful as for other +events.

+ +

The position reporting functions are accurate only outside of the +DTD. In other words, they usually return bogus information when +called from within a DTD declaration handler.

+ +
+enum XML_Error XMLCALL
+XML_GetErrorCode(XML_Parser p);
+
+
+Return what type of error has occurred. +
+ +
+const XML_LChar * XMLCALL
+XML_ErrorString(enum XML_Error code);
+
+
+Return a string describing the error corresponding to code. +The code should be one of the enums that can be returned from +XML_GetErrorCode. +
+ +
+XML_Index XMLCALL
+XML_GetCurrentByteIndex(XML_Parser p);
+
+
+Return the byte offset of the position. This always corresponds to +the values returned by XML_GetCurrentLineNumber and XML_GetCurrentColumnNumber. +
+ +
+XML_Size XMLCALL
+XML_GetCurrentLineNumber(XML_Parser p);
+
+
+Return the line number of the position. The first line is reported as +1. +
+ +
+XML_Size XMLCALL
+XML_GetCurrentColumnNumber(XML_Parser p);
+
+
+Return the offset, from the beginning of the current line, of +the position. +
+ +
+int XMLCALL
+XML_GetCurrentByteCount(XML_Parser p);
+
+
+Return the number of bytes in the current event. Returns +0 if the event is inside a reference to an internal +entity and for the end-tag event for empty element tags (the later can +be used to distinguish empty-element tags from empty elements using +separate start and end tags). +
+ +
+const char * XMLCALL
+XML_GetInputContext(XML_Parser p,
+                    int *offset,
+                    int *size);
+
+
+ +

Returns the parser's input buffer, sets the integer pointed at by +offset to the offset within this buffer of the current +parse position, and set the integer pointed at by size to +the size of the returned buffer.

+ +

This should only be called from within a handler during an active +parse and the returned buffer should only be referred to from within +the handler that made the call. This input buffer contains the +untranslated bytes of the input.

+ +

Only a limited amount of context is kept, so if the event +triggering a call spans over a very large amount of input, the actual +parse position may be before the beginning of the buffer.

+ +

If XML_CONTEXT_BYTES is not defined, this will always +return NULL.

+
+ +

Miscellaneous functions

+ +

The functions in this section either obtain state information from +the parser or can be used to dynamically set parser options.

+ +
+void XMLCALL
+XML_SetUserData(XML_Parser p,
+                void *userData);
+
+
+This sets the user data pointer that gets passed to handlers. It +overwrites any previous value for this pointer. Note that the +application is responsible for freeing the memory associated with +userData when it is finished with the parser. So if you +call this when there's already a pointer there, and you haven't freed +the memory associated with it, then you've probably just leaked +memory. +
+ +
+void * XMLCALL
+XML_GetUserData(XML_Parser p);
+
+
+This returns the user data pointer that gets passed to handlers. +It is actually implemented as a macro. +
+ +
+void XMLCALL
+XML_UseParserAsHandlerArg(XML_Parser p);
+
+
+After this is called, handlers receive the parser in their +userData arguments. The user data can still be obtained +using the XML_GetUserData function. +
+ +
+enum XML_Status XMLCALL
+XML_SetBase(XML_Parser p,
+            const XML_Char *base);
+
+
+Set the base to be used for resolving relative URIs in system +identifiers. The return value is XML_STATUS_ERROR if +there's no memory to store base, otherwise it's +XML_STATUS_OK. +
+ +
+const XML_Char * XMLCALL
+XML_GetBase(XML_Parser p);
+
+
+Return the base for resolving relative URIs. +
+ +
+int XMLCALL
+XML_GetSpecifiedAttributeCount(XML_Parser p);
+
+
+When attributes are reported to the start handler in the atts vector, +attributes that were explicitly set in the element occur before any +attributes that receive their value from default information in an +ATTLIST declaration. This function returns the number of attributes +that were explicitly set times two, thus giving the offset in the +atts array passed to the start tag handler of the first +attribute set due to defaults. It supplies information for the last +call to a start handler. If called inside a start handler, then that +means the current call. +
+ +
+int XMLCALL
+XML_GetIdAttributeIndex(XML_Parser p);
+
+
+Returns the index of the ID attribute passed in the atts array in the +last call to XML_StartElementHandler, or -1 if there is no ID +attribute. If called inside a start handler, then that means the +current call. +
+ +
+const XML_AttrInfo * XMLCALL
+XML_GetAttributeInfo(XML_Parser parser);
+
+
+typedef struct {
+  XML_Index  nameStart;  /* Offset to beginning of the attribute name. */
+  XML_Index  nameEnd;    /* Offset after the attribute name's last byte. */
+  XML_Index  valueStart; /* Offset to beginning of the attribute value. */
+  XML_Index  valueEnd;   /* Offset after the attribute value's last byte. */
+} XML_AttrInfo;
+
+
+Returns an array of XML_AttrInfo structures for the +attribute/value pairs passed in the last call to the +XML_StartElementHandler that were specified +in the start-tag rather than defaulted. Each attribute/value pair counts +as 1; thus the number of entries in the array is +XML_GetSpecifiedAttributeCount(parser) / 2. +
+ +
+enum XML_Status XMLCALL
+XML_SetEncoding(XML_Parser p,
+                const XML_Char *encoding);
+
+
+Set the encoding to be used by the parser. It is equivalent to +passing a non-null encoding argument to the parser creation functions. +It must not be called after XML_Parse or XML_ParseBuffer have been called on the given parser. +Returns XML_STATUS_OK on success or +XML_STATUS_ERROR on error. +
+ +
+int XMLCALL
+XML_SetParamEntityParsing(XML_Parser p,
+                          enum XML_ParamEntityParsing code);
+
+
+This enables parsing of parameter entities, including the external +parameter entity that is the external DTD subset, according to +code. +The choices for code are: +
    +
  • XML_PARAM_ENTITY_PARSING_NEVER
    • +
  • XML_PARAM_ENTITY_PARSING_UNLESS_STANDALONE
    • +
  • XML_PARAM_ENTITY_PARSING_ALWAYS
    • +
+Note: If XML_SetParamEntityParsing is called after +XML_Parse or XML_ParseBuffer, then it has +no effect and will always return 0. +
+ +
+int XMLCALL
+XML_SetHashSalt(XML_Parser p,
+                unsigned long hash_salt);
+
+
+Sets the hash salt to use for internal hash calculations. +Helps in preventing DoS attacks based on predicting hash +function behavior. In order to have an effect this must be called +before parsing has started. Returns 1 if successful, 0 when called +after XML_Parse or XML_ParseBuffer. +

Note:This call is optional, as the parser will auto-generate +a new random salt value if no value has been set at the start of parsing. +

Note:One should not call XML_SetHashSalt with a +hash salt value of 0, as this value is used as sentinel value to indicate +that XML_SetHashSalt has not been called. Consequently +such a call will have no effect, even if it returns 1.

+

+XML_UseForeignDTD(XML_Parser parser, XML_Bool useDTD);
+
+
+

This function allows an application to provide an external subset +for the document type declaration for documents which do not specify +an external subset of their own. For documents which specify an +external subset in their DOCTYPE declaration, the application-provided +subset will be ignored. If the document does not contain a DOCTYPE +declaration at all and useDTD is true, the +application-provided subset will be parsed, but the +startDoctypeDeclHandler and +endDoctypeDeclHandler functions, if set, will not be +called. The setting of parameter entity parsing, controlled using +XML_SetParamEntityParsing, will be honored.

+ +

The application-provided external subset is read by calling the +external entity reference handler set via XML_SetExternalEntityRefHandler with both +publicId and systemId set to NULL.

+ +

If this function is called after parsing has begun, it returns +XML_ERROR_CANT_CHANGE_FEATURE_ONCE_PARSING and ignores +useDTD. If called when Expat has been compiled without +DTD support, it returns +XML_ERROR_FEATURE_REQUIRES_XML_DTD. Otherwise, it +returns XML_ERROR_NONE.

+ +

Note: For the purpose of checking WFC: Entity Declared, passing +useDTD == XML_TRUE will make the parser behave as if +the document had a DTD with an external subset. This holds true even if +the external entity reference handler returns without action.

+
+ +
+void XMLCALL
+XML_SetReturnNSTriplet(XML_Parser parser,
+                       int        do_nst);
+
+
+

+This function only has an effect when using a parser created with +XML_ParserCreateNS, +i.e. when namespace processing is in effect. The do_nst +sets whether or not prefixes are returned with names qualified with a +namespace prefix. If this function is called with do_nst +non-zero, then afterwards namespace qualified names (that is qualified +with a prefix as opposed to belonging to a default namespace) are +returned as a triplet with the three parts separated by the namespace +separator specified when the parser was created. The order of +returned parts is URI, local name, and prefix.

If +do_nst is zero, then namespaces are reported in the +default manner, URI then local_name separated by the namespace +separator.

+
+ +
+void XMLCALL
+XML_DefaultCurrent(XML_Parser parser);
+
+
+This can be called within a handler for a start element, end element, +processing instruction or character data. It causes the corresponding +markup to be passed to the default handler set by XML_SetDefaultHandler or +XML_SetDefaultHandlerExpand. It does nothing if there is +not a default handler. +
+ +
+XML_LChar * XMLCALL
+XML_ExpatVersion();
+
+
+Return the library version as a string (e.g. "expat_1.95.1"). +
+ +
+struct XML_Expat_Version XMLCALL
+XML_ExpatVersionInfo();
+
+
+typedef struct {
+  int major;
+  int minor;
+  int micro;
+} XML_Expat_Version;
+
+
+Return the library version information as a structure. +Some macros are also defined that support compile-time tests of the +library version: +
    +
  • XML_MAJOR_VERSION
    • +
  • XML_MINOR_VERSION
    • +
  • XML_MICRO_VERSION
    • +
+Testing these constants is currently the best way to determine if +particular parts of the Expat API are available. +
+ +
+const XML_Feature * XMLCALL
+XML_GetFeatureList();
+
+
+enum XML_FeatureEnum {
+  XML_FEATURE_END = 0,
+  XML_FEATURE_UNICODE,
+  XML_FEATURE_UNICODE_WCHAR_T,
+  XML_FEATURE_DTD,
+  XML_FEATURE_CONTEXT_BYTES,
+  XML_FEATURE_MIN_SIZE,
+  XML_FEATURE_SIZEOF_XML_CHAR,
+  XML_FEATURE_SIZEOF_XML_LCHAR,
+  XML_FEATURE_NS,
+  XML_FEATURE_LARGE_SIZE
+};
+
+typedef struct {
+  enum XML_FeatureEnum  feature;
+  XML_LChar            *name;
+  long int              value;
+} XML_Feature;
+
+
+

Returns a list of "feature" records, providing details on how +Expat was configured at compile time. Most applications should not +need to worry about this, but this information is otherwise not +available from Expat. This function allows code that does need to +check these features to do so at runtime.

+ +

The return value is an array of XML_Feature, +terminated by a record with a feature of +XML_FEATURE_END and name of NULL, +identifying the feature-test macros Expat was compiled with. Since an +application that requires this kind of information needs to determine +the type of character the name points to, records for the +XML_FEATURE_SIZEOF_XML_CHAR and +XML_FEATURE_SIZEOF_XML_LCHAR will be located at the +beginning of the list, followed by XML_FEATURE_UNICODE +and XML_FEATURE_UNICODE_WCHAR_T, if they are present at +all.

+ +

Some features have an associated value. If there isn't an +associated value, the value field is set to 0. At this +time, the following features have been defined to have values:

+ +
+
XML_FEATURE_SIZEOF_XML_CHAR
+
The number of bytes occupied by one XML_Char + character.
+
XML_FEATURE_SIZEOF_XML_LCHAR
+
The number of bytes occupied by one XML_LChar + character.
+
XML_FEATURE_CONTEXT_BYTES
+
The maximum number of characters of context which can be + reported by XML_GetInputContext.
+
+
+ +
+void XMLCALL
+XML_FreeContentModel(XML_Parser parser, XML_Content *model);
+
+
+Function to deallocate the model argument passed to the +XML_ElementDeclHandler callback set using XML_ElementDeclHandler. +This function should not be used for any other purpose. +
+ +

The following functions allow external code to share the memory +allocator an XML_Parser has been configured to use. This +is especially useful for third-party libraries that interact with a +parser object created by application code, or heavily layered +applications. This can be essential when using dynamically loaded +libraries which use different C standard libraries (this can happen on +Windows, at least).

+ +
+void * XMLCALL
+XML_MemMalloc(XML_Parser parser, size_t size);
+
+
+Allocate size bytes of memory using the allocator the +parser object has been configured to use. Returns a +pointer to the memory or NULL on failure. Memory allocated in this +way must be freed using XML_MemFree. +
+ +
+void * XMLCALL
+XML_MemRealloc(XML_Parser parser, void *ptr, size_t size);
+
+
+Allocate size bytes of memory using the allocator the +parser object has been configured to use. +ptr must point to a block of memory allocated by XML_MemMalloc or +XML_MemRealloc, or be NULL. This function tries to +expand the block pointed to by ptr if possible. Returns +a pointer to the memory or NULL on failure. On success, the original +block has either been expanded or freed. On failure, the original +block has not been freed; the caller is responsible for freeing the +original block. Memory allocated in this way must be freed using +XML_MemFree. +
+ +
+void XMLCALL
+XML_MemFree(XML_Parser parser, void *ptr);
+
+
+Free a block of memory pointed to by ptr. The block must +have been allocated by XML_MemMalloc or XML_MemRealloc, or be NULL. +
+ +

(describe namespaces) + disables namespaces. + + + + + + + + + Adds a doctype and notation declarations to canonical XML output. + This matches the example output used by the formal XML test cases. + Requires to specify an output file. + + + + + + + + + Tells xmlwf to process external DTDs and parameter + entities. + + + Normally &dhpackage; never parses parameter + entities. tells it to always parse them. + implies . + + + + + + + + + Normally &dhpackage; memory-maps the XML file + before parsing; this can result in faster parsing on many + platforms. + turns off memory-mapping and uses normal file + IO calls instead. + Of course, memory-mapping is automatically turned off + when reading from standard input. + + + Use of memory-mapping can cause some platforms to report + substantially higher memory usage for + &dhpackage;, but this appears to be a matter of + the operating system reporting memory in a strange way; there is + not a leak in &dhpackage;. + + + + + + + + + Prints an error if the document is not standalone. + A document is standalone if it has no external subset and no + references to parameter entities. + + + + + + + + + Turns on timings. This tells Expat to parse the entire file, + but not perform any processing. + This gives a fairly accurate idea of the raw speed of Expat itself + without client overhead. + turns off most of the output options + (, , , ...). + + + + + + + + + Prints the version of the Expat library being used, including some + information on the compile-time configuration of the library, and + then exits. + + + + + + + + + Enables support for Windows code pages. + Normally, &dhpackage; will throw an error if it + runs across an encoding that it is not equipped to handle itself. With + , &dhpackage; will try to use a Windows code + page. See also . + + + + + + + + + Turns on parsing external entities. + + + Non-validating parsers are not required to resolve external + entities, or even expand entities at all. + Expat always expands internal entities (?), + but external entity parsing must be enabled explicitly. + + + External entities are simply entities that obtain their + data from outside the XML file currently being parsed. + + + This is an example of an internal entity: + +<!ENTITY vers '1.0.2'> + + + + And here are some examples of external entities: + + +<!ENTITY header SYSTEM "header-&vers;.xml"> (parsed) +<!ENTITY logo SYSTEM "logo.png" PNG> (unparsed) + + + + + + + + + + + (Two hyphens.) + Terminates the list of options. This is only needed if a filename + starts with a hyphen. For example: + + +&dhpackage; -- -myfile.xml + + + will run &dhpackage; on the file + -myfile.xml. + + + + + + + Older versions of &dhpackage; do not support + reading from standard input. + + + + + OUTPUT + + If an input file is not well-formed, + &dhpackage; prints a single line describing + the problem to standard output. If a file is well formed, + &dhpackage; outputs nothing. + Note that the result code is not set. + + + + + BUGS + + &dhpackage; returns a 0 - noerr result, + even if the file is not well-formed. There is no good way for + a program to use &dhpackage; to quickly + check a file -- it must parse &dhpackage;'s + standard output. + + + The errors should go to standard error, not standard output. + + + There should be a way to get to send its + output to standard output rather than forcing the user to send + it to a file. + + + I have no idea why anyone would want to use the + , , and + options.

This + * implementation employs two data structures: a struct sipkey for + * representing the key, and a struct siphash for representing the hash + * state. + * + * For converting a 16-byte unsigned char array to a key, use either the + * macro sip_keyof or the routine sip_tokey. The former instantiates a + * compound literal key, while the latter requires a key object as a + * parameter. + * + * unsigned char secret[16]; + * arc4random_buf(secret, sizeof secret); + * struct sipkey *key = sip_keyof(secret); + * + * For hashing a message, use either the convenience macro siphash24 or the + * routines sip24_init, sip24_update, and sip24_final. + * + * struct siphash state; + * void *msg; + * size_t len; + * uint64_t hash; + * + * sip24_init(&state, key); + * sip24_update(&state, msg, len); + * hash = sip24_final(&state); + * + * or + * + * hash = siphash24(msg, len, key); + * + * To convert the 64-bit hash value to a canonical 8-byte little-endian + * binary representation, use either the macro sip_binof or the routine + * sip_tobin. The former instantiates and returns a compound literal array, + * while the latter requires an array object as a parameter. + * -------------------------------------------------------------------------- + * NOTES: + * + * o Neither sip_keyof, sip_binof, nor siphash24 will work with compilers + * lacking compound literal support.

This file is offered as-is, +without warranty of any kind. + +Basic Installation +================== + + Briefly, the shell commands `./configure; make; make install' should +configure, build, and install this package. The following +more-detailed instructions are generic; see the `README' file for +instructions specific to this package. Some packages provide this +`INSTALL' file but do not implement all of the features documented +below. The lack of an optional feature in a given package is not +necessarily a bug. More recommendations for GNU packages can be found +in *note Makefile Conventions: (standards)Makefile Conventions. + + The `configure' shell script attempts to guess correct values for +various system-dependent variables used during compilation. It uses +those values to create a `Makefile' in each directory of the package. +It may also create one or more `.h' files containing system-dependent +definitions. Finally, it creates a shell script `config.status' that +you can run in the future to recreate the current configuration, and a +file `config.log' containing compiler output (useful mainly for +debugging `configure'). + + It can also use an optional file (typically called `config.cache' +and enabled with `--cache-file=config.cache' or simply `-C') that saves +the results of its tests to speed up reconfiguring. Caching is +disabled by default to prevent problems with accidental use of stale +cache files. + + If you need to do unusual things to compile the package, please try +to figure out how `configure' could check whether to do them, and mail +diffs or instructions to the address given in the `README' so they can +be considered for the next release. If you are using the cache, and at +some point `config.cache' contains results you don't want to keep, you +may remove or edit it. + + The file `configure.ac' (or `configure.in') is used to create +`configure' by a program called `autoconf'. You need `configure.ac' if +you want to change it or regenerate `configure' using a newer version +of `autoconf'. + + The simplest way to compile this package is: + + 1. `cd' to the directory containing the package's source code and type + `./configure' to configure the package for your system. + + Running `configure' might take a while. While running, it prints + some messages telling which features it is checking for. + + 2. Type `make' to compile the package. + + 3. Optionally, type `make check' to run any self-tests that come with + the package, generally using the just-built uninstalled binaries. + + 4. Type `make install' to install the programs and any data files and + documentation. When installing into a prefix owned by root, it is + recommended that the package be configured and built as a regular + user, and only the `make install' phase executed with root + privileges. + + 5. Optionally, type `make installcheck' to repeat any self-tests, but + this time using the binaries in their final installed location. + This target does not install anything. Running this target as a + regular user, particularly if the prior `make install' required + root privileges, verifies that the installation completed + correctly. + + 6. You can remove the program binaries and object files from the + source code directory by typing `make clean'. To also remove the + files that `configure' created (so you can compile the package for + a different kind of computer), type `make distclean'. There is + also a `make maintainer-clean' target, but that is intended mainly + for the package's developers. If you use it, you may have to get + all sorts of other programs in order to regenerate files that came + with the distribution. + + 7. Often, you can also type `make uninstall' to remove the installed + files again. In practice, not all packages have tested that + uninstallation works correctly, even though it is required by the + GNU Coding Standards. + + 8. Some packages, particularly those that use Automake, provide `make + distcheck', which can by used by developers to test that all other + targets like `make install' and `make uninstall' work correctly. + This target is generally not run by end users. + +Compilers and Options +===================== + + Some systems require unusual options for compilation or linking that +the `configure' script does not know about. Run `./configure --help' +for details on some of the pertinent environment variables. + + You can give `configure' initial values for configuration parameters +by setting variables in the command line or in the environment. Here +is an example: + + ./configure CC=c99 CFLAGS=-g LIBS=-lposix + + *Note Defining Variables::, for more details. + +Compiling For Multiple Architectures +==================================== + + You can compile the package for more than one kind of computer at the +same time, by placing the object files for each architecture in their +own directory. To do this, you can use GNU `make'. `cd' to the +directory where you want the object files and executables to go and run +the `configure' script. `configure' automatically checks for the +source code in the directory that `configure' is in and in `..'. This +is known as a "VPATH" build. + + With a non-GNU `make', it is safer to compile the package for one +architecture at a time in the source code directory. After you have +installed the package for one architecture, use `make distclean' before +reconfiguring for another architecture. + + On MacOS X 10.5 and later systems, you can create libraries and +executables that work on multiple system types--known as "fat" or +"universal" binaries--by specifying multiple `-arch' options to the +compiler but only a single `-arch' option to the preprocessor. Like +this: + + ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ + CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ + CPP="gcc -E" CXXCPP="g++ -E" + + This is not guaranteed to produce working output in all cases, you +may have to build one architecture at a time and combine the results +using the `lipo' tool if you have problems. + +Installation Names +================== + + By default, `make install' installs the package's commands under +`/usr/local/bin', include files under `/usr/local/include', etc. You +can specify an installation prefix other than `/usr/local' by giving +`configure' the option `--prefix=PREFIX', where PREFIX must be an +absolute file name. + + You can specify separate installation prefixes for +architecture-specific files and architecture-independent files. If you +pass the option `--exec-prefix=PREFIX' to `configure', the package uses +PREFIX as the prefix for installing programs and libraries. +Documentation and other data files still use the regular prefix. + + In addition, if you use an unusual directory layout you can give +options like `--bindir=DIR' to specify different values for particular +kinds of files. Run `configure --help' for a list of the directories +you can set and what kinds of files go in them. In general, the +default for these options is expressed in terms of `${prefix}', so that +specifying just `--prefix' will affect all of the other directory +specifications that were not explicitly provided. + + The most portable way to affect installation locations is to pass the +correct locations to `configure'; however, many packages provide one or +both of the following shortcuts of passing variable assignments to the +`make install' command line to change installation locations without +having to reconfigure or recompile. + + The first method involves providing an override variable for each +affected directory. For example, `make install +prefix=/alternate/directory' will choose an alternate location for all +directory configuration variables that were expressed in terms of +`${prefix}'. Any directories that were specified during `configure', +but not in terms of `${prefix}', must each be overridden at install +time for the entire installation to be relocated. The approach of +makefile variable overrides for each directory variable is required by +the GNU Coding Standards, and ideally causes no recompilation. +However, some platforms have known limitations with the semantics of +shared libraries that end up requiring recompilation when using this +method, particularly noticeable in packages that use GNU Libtool. + + The second method involves providing the `DESTDIR' variable. For +example, `make install DESTDIR=/alternate/directory' will prepend +`/alternate/directory' before all installation names. The approach of +`DESTDIR' overrides is not required by the GNU Coding Standards, and +does not work on platforms that have drive letters. On the other hand, +it does better at avoiding recompilation issues, and works well even +when some directory options were not specified in terms of `${prefix}' +at `configure' time. + +Optional Features +================= + + If the package supports it, you can cause programs to be installed +with an extra prefix or suffix on their names by giving `configure' the +option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. + + Some packages pay attention to `--enable-FEATURE' options to +`configure', where FEATURE indicates an optional part of the package. +They may also pay attention to `--with-PACKAGE' options, where PACKAGE +is something like `gnu-as' or `x' (for the X Window System). The +`README' should mention any `--enable-' and `--with-' options that the +package recognizes. + + For packages that use the X Window System, `configure' can usually +find the X include and library files automatically, but if it doesn't, +you can use the `configure' options `--x-includes=DIR' and +`--x-libraries=DIR' to specify their locations. + + Some packages offer the ability to configure how verbose the +execution of `make' will be. For these packages, running `./configure +--enable-silent-rules' sets the default to minimal output, which can be +overridden with `make V=1'; while running `./configure +--disable-silent-rules' sets the default to verbose, which can be +overridden with `make V=0'. + +Particular systems +================== + + On HP-UX, the default C compiler is not ANSI C compatible. If GNU +CC is not installed, it is recommended to use the following options in +order to use an ANSI C compiler: + + ./configure CC="cc -Ae -D_XOPEN_SOURCE=500" + +and if that doesn't work, install pre-built binaries of GCC for HP-UX. + + On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot +parse its `' header file. The option `-nodtk' can be used as +a workaround. If GNU CC is not installed, it is therefore recommended +to try + + ./configure CC="cc" + +and if that doesn't work, try + + ./configure CC="cc -nodtk" + + On Solaris, don't put `/usr/ucb' early in your `PATH'. This +directory contains several dysfunctional programs; working variants of +these programs are available in `/usr/bin'. So, if you need `/usr/ucb' +in your `PATH', put it _after_ `/usr/bin'. + + On Haiku, software installed for all users goes in `/boot/common', +not `/usr/local'. It is recommended to use the following options: + + ./configure --prefix=/boot/common + +Specifying the System Type +========================== + + There may be some features `configure' cannot figure out +automatically, but needs to determine by the type of machine the package +will run on. Usually, assuming the package is built to be run on the +_same_ architectures, `configure' can figure that out, but if it prints +a message saying it cannot guess the machine type, give it the +`--build=TYPE' option. TYPE can either be a short name for the system +type, such as `sun4', or a canonical name which has the form: + + CPU-COMPANY-SYSTEM + +where SYSTEM can have one of these forms: + + OS + KERNEL-OS + + See the file `config.sub' for the possible values of each field. If +`config.sub' isn't included in this package, then this package doesn't +need to know the machine type. + + If you are _building_ compiler tools for cross-compiling, you should +use the option `--target=TYPE' to select the type of system they will +produce code for. + + If you want to _use_ a cross compiler, that generates code for a +platform different from the build platform, you should specify the +"host" platform (i.e., that on which the generated programs will +eventually be run) with `--host=TYPE'. + +Sharing Defaults +================ + + If you want to set default values for `configure' scripts to share, +you can create a site shell script called `config.site' that gives +default values for variables like `CC', `cache_file', and `prefix'. +`configure' looks for `PREFIX/share/config.site' if it exists, then +`PREFIX/etc/config.site' if it exists. Or, you can set the +`CONFIG_SITE' environment variable to the location of the site script. +A warning: not all `configure' scripts look for a site script. + +Defining Variables +================== + + Variables not defined in a site shell script can be set in the +environment passed to `configure'. However, some packages may run +configure again during the build, and the customized values of these +variables may be lost. In order to avoid this problem, you should set +them in the `configure' command line, using `VAR=value'. For example: + + ./configure CC=/usr/local2/bin/gcc + +causes the specified `gcc' to be used as the C compiler (unless it is +overridden in the site shell script). + +Unfortunately, this technique does not work for `CONFIG_SHELL' due to +an Autoconf bug. Until the bug is fixed you can use this workaround: + + CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash + +`configure' Invocation +====================== + + `configure' recognizes the following options to control how it +operates. + +`--help' +`-h' + Print a summary of all of the options to `configure', and exit. + +`--help=short' +`--help=recursive' + Print a summary of the options unique to this package's + `configure', and exit.

It +# sets the PTHREAD_LIBS output variable to the threads library and linker +# flags, and the PTHREAD_CFLAGS output variable to any special C compiler +# flags that are needed. (The user can also force certain compiler +# flags/libs to be tested by setting these environment variables.) +# +# Also sets PTHREAD_CC to any special C compiler that is needed for +# multi-threaded programs (defaults to the value of CC otherwise). (This +# is necessary on AIX to use the special cc_r compiler alias.) +# +# NOTE: You are assumed to not only compile your program with these flags, +# but also link it with them as well. e.g. you should link with +# $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS +# +# If you are only building threads programs, you may wish to use these +# variables in your default LIBS, CFLAGS, and CC: +# +# LIBS="$PTHREAD_LIBS $LIBS" +# CFLAGS="$CFLAGS $PTHREAD_CFLAGS" +# CC="$PTHREAD_CC" +# +# In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant +# has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to that name +# (e.g. PTHREAD_CREATE_UNDETACHED on AIX). +# +# Also HAVE_PTHREAD_PRIO_INHERIT is defined if pthread is found and the +# PTHREAD_PRIO_INHERIT symbol is defined when compiling with +# PTHREAD_CFLAGS. +# +# ACTION-IF-FOUND is a list of shell commands to run if a threads library +# is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it +# is not found. If ACTION-IF-FOUND is not specified, the default action +# will define HAVE_PTHREAD. +# +# Please let the authors know if this macro fails on any platform, or if +# you have any other suggestions or comments. This macro was based on work +# by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help +# from M. Frigo), as well as ac_pthread and hb_pthread macros posted by +# Alejandro Forero Cuervo to the autoconf macro repository.

This file is offered as-is, +without warranty of any kind. + +Basic Installation +================== + + Briefly, the shell command `./configure && make && make install' +should configure, build, and install this package. The following +more-detailed instructions are generic; see the `README' file for +instructions specific to this package. Some packages provide this +`INSTALL' file but do not implement all of the features documented +below. The lack of an optional feature in a given package is not +necessarily a bug. More recommendations for GNU packages can be found +in *note Makefile Conventions: (standards)Makefile Conventions. + + The `configure' shell script attempts to guess correct values for +various system-dependent variables used during compilation. It uses +those values to create a `Makefile' in each directory of the package. +It may also create one or more `.h' files containing system-dependent +definitions. Finally, it creates a shell script `config.status' that +you can run in the future to recreate the current configuration, and a +file `config.log' containing compiler output (useful mainly for +debugging `configure'). + + It can also use an optional file (typically called `config.cache' +and enabled with `--cache-file=config.cache' or simply `-C') that saves +the results of its tests to speed up reconfiguring. Caching is +disabled by default to prevent problems with accidental use of stale +cache files. + + If you need to do unusual things to compile the package, please try +to figure out how `configure' could check whether to do them, and mail +diffs or instructions to the address given in the `README' so they can +be considered for the next release. If you are using the cache, and at +some point `config.cache' contains results you don't want to keep, you +may remove or edit it. + + The file `configure.ac' (or `configure.in') is used to create +`configure' by a program called `autoconf'. You need `configure.ac' if +you want to change it or regenerate `configure' using a newer version +of `autoconf'. + + The simplest way to compile this package is: + + 1. `cd' to the directory containing the package's source code and type + `./configure' to configure the package for your system. + + Running `configure' might take a while. While running, it prints + some messages telling which features it is checking for. + + 2. Type `make' to compile the package. + + 3. Optionally, type `make check' to run any self-tests that come with + the package, generally using the just-built uninstalled binaries. + + 4. Type `make install' to install the programs and any data files and + documentation. When installing into a prefix owned by root, it is + recommended that the package be configured and built as a regular + user, and only the `make install' phase executed with root + privileges. + + 5. Optionally, type `make installcheck' to repeat any self-tests, but + this time using the binaries in their final installed location. + This target does not install anything. Running this target as a + regular user, particularly if the prior `make install' required + root privileges, verifies that the installation completed + correctly. + + 6. You can remove the program binaries and object files from the + source code directory by typing `make clean'. To also remove the + files that `configure' created (so you can compile the package for + a different kind of computer), type `make distclean'. There is + also a `make maintainer-clean' target, but that is intended mainly + for the package's developers. If you use it, you may have to get + all sorts of other programs in order to regenerate files that came + with the distribution. + + 7. Often, you can also type `make uninstall' to remove the installed + files again. In practice, not all packages have tested that + uninstallation works correctly, even though it is required by the + GNU Coding Standards. + + 8. Some packages, particularly those that use Automake, provide `make + distcheck', which can by used by developers to test that all other + targets like `make install' and `make uninstall' work correctly. + This target is generally not run by end users. + +Compilers and Options +===================== + + Some systems require unusual options for compilation or linking that +the `configure' script does not know about. Run `./configure --help' +for details on some of the pertinent environment variables. + + You can give `configure' initial values for configuration parameters +by setting variables in the command line or in the environment. Here +is an example: + + ./configure CC=c99 CFLAGS=-g LIBS=-lposix + + *Note Defining Variables::, for more details. + +Compiling For Multiple Architectures +==================================== + + You can compile the package for more than one kind of computer at the +same time, by placing the object files for each architecture in their +own directory. To do this, you can use GNU `make'. `cd' to the +directory where you want the object files and executables to go and run +the `configure' script. `configure' automatically checks for the +source code in the directory that `configure' is in and in `..'. This +is known as a "VPATH" build. + + With a non-GNU `make', it is safer to compile the package for one +architecture at a time in the source code directory. After you have +installed the package for one architecture, use `make distclean' before +reconfiguring for another architecture. + + On MacOS X 10.5 and later systems, you can create libraries and +executables that work on multiple system types--known as "fat" or +"universal" binaries--by specifying multiple `-arch' options to the +compiler but only a single `-arch' option to the preprocessor. Like +this: + + ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ + CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ + CPP="gcc -E" CXXCPP="g++ -E" + + This is not guaranteed to produce working output in all cases, you +may have to build one architecture at a time and combine the results +using the `lipo' tool if you have problems. + +Installation Names +================== + + By default, `make install' installs the package's commands under +`/usr/local/bin', include files under `/usr/local/include', etc. You +can specify an installation prefix other than `/usr/local' by giving +`configure' the option `--prefix=PREFIX', where PREFIX must be an +absolute file name. + + You can specify separate installation prefixes for +architecture-specific files and architecture-independent files. If you +pass the option `--exec-prefix=PREFIX' to `configure', the package uses +PREFIX as the prefix for installing programs and libraries. +Documentation and other data files still use the regular prefix. + + In addition, if you use an unusual directory layout you can give +options like `--bindir=DIR' to specify different values for particular +kinds of files. Run `configure --help' for a list of the directories +you can set and what kinds of files go in them. In general, the +default for these options is expressed in terms of `${prefix}', so that +specifying just `--prefix' will affect all of the other directory +specifications that were not explicitly provided. + + The most portable way to affect installation locations is to pass the +correct locations to `configure'; however, many packages provide one or +both of the following shortcuts of passing variable assignments to the +`make install' command line to change installation locations without +having to reconfigure or recompile. + + The first method involves providing an override variable for each +affected directory. For example, `make install +prefix=/alternate/directory' will choose an alternate location for all +directory configuration variables that were expressed in terms of +`${prefix}'. Any directories that were specified during `configure', +but not in terms of `${prefix}', must each be overridden at install +time for the entire installation to be relocated. The approach of +makefile variable overrides for each directory variable is required by +the GNU Coding Standards, and ideally causes no recompilation. +However, some platforms have known limitations with the semantics of +shared libraries that end up requiring recompilation when using this +method, particularly noticeable in packages that use GNU Libtool. + + The second method involves providing the `DESTDIR' variable. For +example, `make install DESTDIR=/alternate/directory' will prepend +`/alternate/directory' before all installation names. The approach of +`DESTDIR' overrides is not required by the GNU Coding Standards, and +does not work on platforms that have drive letters. On the other hand, +it does better at avoiding recompilation issues, and works well even +when some directory options were not specified in terms of `${prefix}' +at `configure' time. + +Optional Features +================= + + If the package supports it, you can cause programs to be installed +with an extra prefix or suffix on their names by giving `configure' the +option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. + + Some packages pay attention to `--enable-FEATURE' options to +`configure', where FEATURE indicates an optional part of the package. +They may also pay attention to `--with-PACKAGE' options, where PACKAGE +is something like `gnu-as' or `x' (for the X Window System). The +`README' should mention any `--enable-' and `--with-' options that the +package recognizes. + + For packages that use the X Window System, `configure' can usually +find the X include and library files automatically, but if it doesn't, +you can use the `configure' options `--x-includes=DIR' and +`--x-libraries=DIR' to specify their locations. + + Some packages offer the ability to configure how verbose the +execution of `make' will be. For these packages, running `./configure +--enable-silent-rules' sets the default to minimal output, which can be +overridden with `make V=1'; while running `./configure +--disable-silent-rules' sets the default to verbose, which can be +overridden with `make V=0'. + +Particular systems +================== + + On HP-UX, the default C compiler is not ANSI C compatible. If GNU +CC is not installed, it is recommended to use the following options in +order to use an ANSI C compiler: + + ./configure CC="cc -Ae -D_XOPEN_SOURCE=500" + +and if that doesn't work, install pre-built binaries of GCC for HP-UX. + + HP-UX `make' updates targets which have the same time stamps as +their prerequisites, which makes it generally unusable when shipped +generated files such as `configure' are involved. Use GNU `make' +instead. + + On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot +parse its `' header file. The option `-nodtk' can be used as +a workaround. If GNU CC is not installed, it is therefore recommended +to try + + ./configure CC="cc" + +and if that doesn't work, try + + ./configure CC="cc -nodtk" + + On Solaris, don't put `/usr/ucb' early in your `PATH'. This +directory contains several dysfunctional programs; working variants of +these programs are available in `/usr/bin'. So, if you need `/usr/ucb' +in your `PATH', put it _after_ `/usr/bin'. + + On Haiku, software installed for all users goes in `/boot/common', +not `/usr/local'. It is recommended to use the following options: + + ./configure --prefix=/boot/common + +Specifying the System Type +========================== + + There may be some features `configure' cannot figure out +automatically, but needs to determine by the type of machine the package +will run on. Usually, assuming the package is built to be run on the +_same_ architectures, `configure' can figure that out, but if it prints +a message saying it cannot guess the machine type, give it the +`--build=TYPE' option. TYPE can either be a short name for the system +type, such as `sun4', or a canonical name which has the form: + + CPU-COMPANY-SYSTEM + +where SYSTEM can have one of these forms: + + OS + KERNEL-OS + + See the file `config.sub' for the possible values of each field. If +`config.sub' isn't included in this package, then this package doesn't +need to know the machine type. + + If you are _building_ compiler tools for cross-compiling, you should +use the option `--target=TYPE' to select the type of system they will +produce code for. + + If you want to _use_ a cross compiler, that generates code for a +platform different from the build platform, you should specify the +"host" platform (i.e., that on which the generated programs will +eventually be run) with `--host=TYPE'. + +Sharing Defaults +================ + + If you want to set default values for `configure' scripts to share, +you can create a site shell script called `config.site' that gives +default values for variables like `CC', `cache_file', and `prefix'. +`configure' looks for `PREFIX/share/config.site' if it exists, then +`PREFIX/etc/config.site' if it exists. Or, you can set the +`CONFIG_SITE' environment variable to the location of the site script. +A warning: not all `configure' scripts look for a site script. + +Defining Variables +================== + + Variables not defined in a site shell script can be set in the +environment passed to `configure'. However, some packages may run +configure again during the build, and the customized values of these +variables may be lost. In order to avoid this problem, you should set +them in the `configure' command line, using `VAR=value'. For example: + + ./configure CC=/usr/local2/bin/gcc + +causes the specified `gcc' to be used as the C compiler (unless it is +overridden in the site shell script). + +Unfortunately, this technique does not work for `CONFIG_SHELL' due to +an Autoconf limitation. Until the limitation is lifted, you can use +this workaround: + + CONFIG_SHELL=/bin/bash ./configure CONFIG_SHELL=/bin/bash + +`configure' Invocation +====================== + + `configure' recognizes the following options to control how it +operates. + +`--help' +`-h' + Print a summary of all of the options to `configure', and exit. + +`--help=short' +`--help=recursive' + Print a summary of the options unique to this package's + `configure', and exit. The `short' variant lists options used + only in the top level, while the `recursive' variant lists options + also present in any nested packages. + +`--version' +`-V' + Print the version of Autoconf used to generate the `configure' + script, and exit. + +`--cache-file=FILE' + Enable the cache: use and save the results of the tests in FILE, + traditionally `config.cache'. FILE defaults to `/dev/null' to + disable caching. + +`--config-cache' +`-C' + Alias for `--cache-file=config.cache'. + +`--quiet' +`--silent' +`-q' + Do not print messages saying which checks are being made. To + suppress all normal output, redirect it to `/dev/null' (any error + messages will still be shown). + +`--srcdir=DIR' + Look for the package's source code in directory DIR. Usually + `configure' can determine that directory automatically. + +`--prefix=DIR' + Use DIR as the installation prefix. *note Installation Names:: + for more details, including other options available for fine-tuning + the installation locations. + +`--no-create' +`-n' + Run the configure checks, but stop before creating any output + files. + +`configure' also accepts some other, not widely useful, options. Run +`configure --help' for more details. diff --git a/src/opus/Makefile.am b/src/opus/Makefile.am new file mode 100644 index 000000000..5b57b3372 --- /dev/null +++ b/src/opus/Makefile.am @@ -0,0

It does not aim for maximum +compression, or compatibility with any other compression library; instead, +it aims for very high speeds and reasonable compression. For instance, +compared to the fastest mode of zlib, Snappy is an order of magnitude faster +for most inputs, but the resulting compressed files are anywhere from 20% to +100% bigger. (For more information, see "Performance", below.) + +Snappy has the following properties: + + * Fast: Compression speeds at 250 MB/sec and beyond, with no assembler code. + See "Performance" below. + * Stable: Over the last few years, Snappy has compressed and decompressed + petabytes of data in Google's production environment. The Snappy bitstream + format is stable and will not change between versions. + * Robust: The Snappy decompressor is designed not to crash in the face of + corrupted or malicious input. + * Free and open source software: Snappy is licensed under a BSD-type license. + For more information, see the included COPYING file. + +Snappy has previously been called "Zippy" in some Google presentations +and the like. + + +Performance +=========== + +Snappy is intended to be fast. On a single core of a Core i7 processor +in 64-bit mode, it compresses at about 250 MB/sec or more and decompresses at +about 500 MB/sec or more. (These numbers are for the slowest inputs in our +benchmark suite; others are much faster.) In our tests, Snappy usually +is faster than algorithms in the same class (e.g. LZO, LZF, QuickLZ, +etc.) while achieving comparable compression ratios. + +Typical compression ratios (based on the benchmark suite) are about 1.5-1.7x +for plain text, about 2-4x for HTML, and of course 1.0x for JPEGs, PNGs and +other already-compressed data. Similar numbers for zlib in its fastest mode +are 2.6-2.8x, 3-7x and 1.0x, respectively. More sophisticated algorithms are +capable of achieving yet higher compression rates, although usually at the +expense of speed. Of course, compression ratio will vary significantly with +the input. + +Although Snappy should be fairly portable, it is primarily optimized +for 64-bit x86-compatible processors, and may run slower in other environments. +In particular: + + - Snappy uses 64-bit operations in several places to process more data at + once than would otherwise be possible. + - Snappy assumes unaligned 32- and 64-bit loads and stores are cheap. + On some platforms, these must be emulated with single-byte loads + and stores, which is much slower. + - Snappy assumes little-endian throughout, and needs to byte-swap data in + several places if running on a big-endian platform. + +Experience has shown that even heavily tuned code can be improved. +Performance optimizations, whether for 64-bit x86 or other platforms, +are of course most welcome; see "Contact", below. + + +Building +======== + +CMake is supported and autotools will soon be deprecated. +You need CMake 3.4 or above to build: + + mkdir build + cd build && cmake ../ && make + + +Usage +===== + +Note that Snappy, both the implementation and the main interface, +is written in C++. However, several third-party bindings to other languages +are available; see the home page at http://google.github.io/snappy/ +for more information. Also, if you want to use Snappy from C code, you can +use the included C bindings in snappy-c.h. + +To use Snappy from your own C++ program, include the file "snappy.h" from +your calling file, and link against the compiled library. + +There are many ways to call Snappy, but the simplest possible is + + snappy::Compress(input.data(), input.size(), &output); + +and similarly + + snappy::Uncompress(input.data(), input.size(), &output); + +where "input" and "output" are both instances of std::string. + +There are other interfaces that are more flexible in various ways, including +support for custom (non-array) input sources. See the header file for more +information. + + +Tests and benchmarks +==================== + +When you compile Snappy, snappy_unittest is compiled in addition to the +library itself. You do not need it to use the compressor from your own library, +but it contains several useful components for Snappy development. + +First of all, it contains unit tests, verifying correctness on your machine in +various scenarios. If you want to change or optimize Snappy, please run the +tests to verify you have not broken anything. Note that if you have the +Google Test library installed, unit test behavior (especially failures) will be +significantly more user-friendly. You can find Google Test at + + http://github.com/google/googletest + +You probably also want the gflags library for handling of command-line flags; +you can find it at + + http://gflags.github.io/gflags/ + +In addition to the unit tests, snappy contains microbenchmarks used to +tune compression and decompression performance. These are automatically run +before the unit tests, but you can disable them using the flag +--run_microbenchmarks=false if you have gflags installed (otherwise you will +need to edit the source). + +Finally, snappy can benchmark Snappy against a few other compression libraries +(zlib, LZO, LZF, and QuickLZ), if they were detected at configure time. +To benchmark using a given file, give the compression algorithm you want to test +Snappy against (e.g. --zlib) and then a list of one or more file names on the +command line.

It is originally based on +text by Zeev Tarantov. + +Snappy is a LZ77-type compressor with a fixed, byte-oriented encoding. +There is no entropy encoder backend nor framing layer -- the latter is +assumed to be handled by other parts of the system. + +This document only describes the format, not how the Snappy compressor nor +decompressor actually works. The correctness of the decompressor should not +depend on implementation details of the compressor, and vice versa. + + +1. Preamble + +The stream starts with the uncompressed length (up to a maximum of 2^32 - 1), +stored as a little-endian varint. Varints consist of a series of bytes, +where the lower 7 bits are data and the upper bit is set iff there are +more bytes to be read. In other words, an uncompressed length of 64 would +be stored as 0x40, and an uncompressed length of 2097150 (0x1FFFFE) +would be stored as 0xFE 0xFF 0x7F. + + +2. The compressed stream itself + +There are two types of elements in a Snappy stream: Literals and +copies (backreferences). There is no restriction on the order of elements, +except that the stream naturally cannot start with a copy. (Having +two literals in a row is never optimal from a compression point of +view, but nevertheless fully permitted.) Each element starts with a tag byte, +and the lower two bits of this tag byte signal what type of element will +follow: + + 00: Literal + 01: Copy with 1-byte offset + 10: Copy with 2-byte offset + 11: Copy with 4-byte offset + +The interpretation of the upper six bits are element-dependent. + + +2.1. Literals (00) + +Literals are uncompressed data stored directly in the byte stream. +The literal length is stored differently depending on the length +of the literal: + + - For literals up to and including 60 bytes in length, the upper + six bits of the tag byte contain (len-1). The literal follows + immediately thereafter in the bytestream. + - For longer literals, the (len-1) value is stored after the tag byte, + little-endian. The upper six bits of the tag byte describe how + many bytes are used for the length; 60, 61, 62 or 63 for + 1-4 bytes, respectively. The literal itself follows after the + length. + + +2.2. Copies + +Copies are references back into previous decompressed data, telling +the decompressor to reuse data it has previously decoded. +They encode two values: The _offset_, saying how many bytes back +from the current position to read, and the _length_, how many bytes +to copy. Offsets of zero can be encoded, but are not legal; +similarly, it is possible to encode backreferences that would +go past the end of the block (offset > current decompressed position), +which is also nonsensical and thus not allowed. + +As in most LZ77-based compressors, the length can be larger than the offset, +yielding a form of run-length encoding (RLE). For instance, +"xababab" could be encoded as + + + +Note that since the current Snappy compressor works in 32 kB +blocks and does not do matching across blocks, it will never produce +a bitstream with offsets larger than about 32768. However, the +decompressor should not rely on this, as it may change in the future. + +There are several different kinds of copy elements, depending on +the amount of bytes to be copied (length), and how far back the +data to be copied is (offset). + + +2.2.1. Copy with 1-byte offset (01) + +These elements can encode lengths between [4..11] bytes and offsets +between [0..2047] bytes. (len-4) occupies three bits and is stored +in bits [2..4] of the tag byte. The offset occupies 11 bits, of which the +upper three are stored in the upper three bits ([5..7]) of the tag byte, +and the lower eight are stored in a byte following the tag byte. + + +2.2.2. Copy with 2-byte offset (10) + +These elements can encode lengths between [1..64] and offsets from +[0..65535]. (len-1) occupies six bits and is stored in the upper +six bits ([2..7]) of the tag byte. The offset is stored as a +little-endian 16-bit integer in the two bytes following the tag byte. + + +2.2.3. Copy with 4-byte offset (11) + +These are like the copies with 2-byte offsets (see previous subsection), +except that the offset is stored as a 32-bit integer instead of a +16-bit integer (and thus will occupy four bytes). diff --git a/src/snappy/framing_format.txt b/src/snappy/framing_format.txt new file mode 100644 index 000000000..9764e83de --- /dev/null +++ b/src/snappy/framing_format.txt @@ -0,0 +1,135 @@ +Snappy framing format description +Last revised: 2013-10-25 + +This format decribes a framing format for Snappy, allowing compressing to +files or streams that can then more easily be decompressed without having +to hold the entire stream in memory. It also provides data checksums to +help verify integrity. It does not provide metadata checksums, so it does +not protect against e.g. all forms of truncations. + +Implementation of the framing format is optional for Snappy compressors and +decompressor; it is not part of the Snappy core specification. + + +1. General structure + +The file consists solely of chunks, lying back-to-back with no padding +in between. Each chunk consists first a single byte of chunk identifier, +then a three-byte little-endian length of the chunk in bytes (from 0 to +16777215, inclusive), and then the data if any. The four bytes of chunk +header is not counted in the data length. + +The different chunk types are listed below. The first chunk must always +be the stream identifier chunk (see section 4.1, below). The stream +ends when the file ends -- there is no explicit end-of-file marker. + + +2. File type identification + +The following identifiers for this format are recommended where appropriate. +However, note that none have been registered officially, so this is only to +be taken as a guideline. We use "Snappy framed" to distinguish between this +format and raw Snappy data. + + File extension: .sz + MIME type: application/x-snappy-framed + HTTP Content-Encoding: x-snappy-framed + + +3. Checksum format + +Some chunks have data protected by a checksum (the ones that do will say so +explicitly). The checksums are always masked CRC-32Cs. + +A description of CRC-32C can be found in RFC 3720, section 12.1, with +examples in section B.4. + +Checksums are not stored directly, but masked, as checksumming data and +then its own checksum can be problematic. The masking is the same as used +in Apache Hadoop: Rotate the checksum by 15 bits, then add the constant +0xa282ead8 (using wraparound as normal for unsigned integers). This is +equivalent to the following C code: + + uint32_t mask_checksum(uint32_t x) { + return ((x >> 15) | (x << 17)) + 0xa282ead8; + } + +Note that the masking is reversible. + +The checksum is always stored as a four bytes long integer, in little-endian. + + +4. Chunk types + +The currently supported chunk types are described below. The list may +be extended in the future. + + +4.1. Stream identifier (chunk type 0xff) + +The stream identifier is always the first element in the stream. +It is exactly six bytes long and contains "sNaPpY" in ASCII. This means that +a valid Snappy framed stream always starts with the bytes + + 0xff 0x06 0x00 0x00 0x73 0x4e 0x61 0x50 0x70 0x59 + +The stream identifier chunk can come multiple times in the stream besides +the first; if such a chunk shows up, it should simply be ignored, assuming +it has the right length and contents. This allows for easy concatenation of +compressed files without the need for re-framing. + + +4.2. Compressed data (chunk type 0x00) + +Compressed data chunks contain a normal Snappy compressed bitstream; +see the compressed format specification. The compressed data is preceded by +the CRC-32C (see section 3) of the _uncompressed_ data. + +Note that the data portion of the chunk, i.e., the compressed contents, +can be at most 16777211 bytes (2^24 - 1, minus the checksum). +However, we place an additional restriction that the uncompressed data +in a chunk must be no longer than 65536 bytes. This allows consumers to +easily use small fixed-size buffers. + + +4.3. Uncompressed data (chunk type 0x01) + +Uncompressed data chunks allow a compressor to send uncompressed, +raw data; this is useful if, for instance, uncompressible or +near-incompressible data is detected, and faster decompression is desired. + +As in the compressed chunks, the data is preceded by its own masked +CRC-32C (see section 3). + +An uncompressed data chunk, like compressed data chunks, should contain +no more than 65536 data bytes, so the maximum legal chunk length with the +checksum is 65540. + + +4.4. Padding (chunk type 0xfe) + +Padding chunks allow a compressor to increase the size of the data stream +so that it complies with external demands, e.g. that the total number of +bytes is a multiple of some value. + +All bytes of the padding chunk, except the chunk byte itself and the length, +should be zero, but decompressors must not try to interpret or verify the +padding data in any way. + + +4.5. Reserved unskippable chunks (chunk types 0x02-0x7f) + +These are reserved for future expansion. A decoder that sees such a chunk +should immediately return an error, as it must assume it cannot decode the +stream correctly. + +Future versions of this specification may define meanings for these chunks. + + +4.6. Reserved skippable chunks (chunk types 0x80-0xfd) + +These are also reserved for future expansion, but unlike the chunks +described in 4.5, a decoder seeing these must skip them and continue +decoding. + +Future versions of this specification may define meanings for these chunks. diff --git a/src/snappy/snappy-c.cc b/src/snappy/snappy-c.cc new file mode 100644 index 000000000..473a0b097 --- /dev/null +++ b/src/snappy/snappy-c.cc @@ -0,0 +1,90 @@ +// Copyright 2011 Martin Gieseking . +// +// Redistribution and use in source and binary forms, with or without +// modification, are permitted provided that the following conditions are +// met: +// +// * Redistributions of source code must retain the above copyright +// notice, this list of conditions and the following disclaimer. +// * Redistributions in binary form must reproduce the above +// copyright notice, this list of conditions and the following disclaimer +// in the documentation and/or other materials provided with the +// distribution. +// * Neither the name of Google Inc. nor the names of its +// contributors may be used to endorse or promote products derived from +// this software without specific prior written permission. +// +// THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS +// "AS IS" AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT +// LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR +// A PARTICULAR PURPOSE ARE DISCLAIMED.

nor did Alice +think it so VERY much out of the way to hear the Rabbit say to +itself, `Oh dear! Oh dear! I shall be late!' (when she thought +it over afterwards, it occurred to her that she ought to have +wondered at this, but at the time it all seemed quite natural); +but when the Rabbit actually TOOK A WATCH OUT OF ITS WAISTCOAT- +POCKET, and looked at it, and then hurried on, Alice started to +her feet, for it flashed across her mind that she had never +before seen a rabbit with either a waistcoat-pocket, or a watch to +take out of it, and burning with curiosity, she ran across the +field after it, and fortunately was just in time to see it pop +down a large rabbit-hole under the hedge. + + In another moment down went Alice after it, never once +considering how in the world she was to get out again. + + The rabbit-hole went straight on like a tunnel for some way, +and then dipped suddenly down, so suddenly that Alice had not a +moment to think about stopping herself before she found herself +falling down a very deep well. + + Either the well was very deep, or she fell very slowly, for she +had plenty of time as she went down to look about her and to +wonder what was going to happen next. First, she tried to look +down and make out what she was coming to, but it was too dark to +see anything; then she looked at the sides of the well, and +noticed that they were filled with cupboards and book-shelves; +here and there she saw maps and pictures hung upon pegs. She +took down a jar from one of the shelves as she passed; it was +labelled `ORANGE MARMALADE', but to her great disappointment it +was empty: she did not like to drop the jar for fear of killing +somebody, so managed to put it into one of the cupboards as she +fell past it. + + `Well!' thought Alice to herself, `after such a fall as this, I +shall think nothing of tumbling down stairs! How brave they'll +all think me at home! Why, I wouldn't say anything about it, +even if I fell off the top of the house!' (Which was very likely +true.) + + Down, down, down. Would the fall NEVER come to an end! `I +wonder how many miles I've fallen by this time?' she said aloud. +`I must be getting somewhere near the centre of the earth. Let +me see: that would be four thousand miles down, I think--' (for, +you see, Alice had learnt several things of this sort in her +lessons in the schoolroom, and though this was not a VERY good +opportunity for showing off her knowledge, as there was no one to +listen to her, still it was good practice to say it over) `--yes, +that's about the right distance--but then I wonder what Latitude +or Longitude I've got to?' (Alice had no idea what Latitude was, +or Longitude either, but thought they were nice grand words to +say.) + + Presently she began again. `I wonder if I shall fall right +THROUGH the earth! How funny it'll seem to come out among the +people that walk with their heads downward! The Antipathies, I +think--' (she was rather glad there WAS no one listening, this +time, as it didn't sound at all the right word) `--but I shall +have to ask them what the name of the country is, you know. +Please, Ma'am, is this New Zealand or Australia?' (and she tried +to curtsey as she spoke--fancy CURTSEYING as you're falling +through the air! Do you think you could manage it?) `And what +an ignorant little girl she'll think me for asking! No, it'll +never do to ask: perhaps I shall see it written up somewhere.' + + Down, down, down. There was nothing else to do, so Alice soon +began talking again. `Dinah'll miss me very much to-night, I +should think!' (Dinah was the cat.) `I hope they'll remember +her saucer of milk at tea-time. Dinah my dear! I wish you were +down here with me! There are no mice in the air, I'm afraid, but +you might catch a bat, and that's very like a mouse, you know. +But do cats eat bats, I wonder?' And here Alice began to get +rather sleepy, and went on saying to herself, in a dreamy sort of +way, `Do cats eat bats? Do cats eat bats?' and sometimes, `Do +bats eat cats?' for, you see, as she couldn't answer either +question, it didn't much matter which way she put it. She felt +that she was dozing off, and had just begun to dream that she +was walking hand in hand with Dinah, and saying to her very +earnestly, `Now, Dinah, tell me the truth: did you ever eat a +bat?' when suddenly, thump! thump! down she came upon a heap of +sticks and dry leaves, and the fall was over. + + Alice was not a bit hurt, and she jumped up on to her feet in a +moment: she looked up, but it was all dark overhead; before her +was another long passage, and the White Rabbit was still in +sight, hurrying down it. There was not a moment to be lost: +away went Alice like the wind, and was just in time to hear it +say, as it turned a corner, `Oh my ears and whiskers, how late +it's getting!' She was close behind it when she turned the +corner, but the Rabbit was no longer to be seen: she found +herself in a long, low hall, which was lit up by a row of lamps +hanging from the roof. + + There were doors all round the hall, but they were all locked; +and when Alice had been all the way down one side and up the +other, trying every door, she walked sadly down the middle, +wondering how she was ever to get out again. + + Suddenly she came upon a little three-legged table, all made of +solid glass; there was nothing on it except a tiny golden key, +and Alice's first thought was that it might belong to one of the +doors of the hall; but, alas! either the locks were too large, or +the key was too small, but at any rate it would not open any of +them. However, on the second time round, she came upon a low +curtain she had not noticed before, and behind it was a little +door about fifteen inches high: she tried the little golden key +in the lock, and to her great delight it fitted! + + Alice opened the door and found that it led into a small +passage, not much larger than a rat-hole: she knelt down and +looked along the passage into the loveliest garden you ever saw. +How she longed to get out of that dark hall, and wander about +among those beds of bright flowers and those cool fountains, but +she could not even get her head though the doorway; `and even if +my head would go through,' thought poor Alice, `it would be of +very little use without my shoulders. Oh, how I wish +I could shut up like a telescope! I think I could, if I only +know how to begin.' For, you see, so many out-of-the-way things +had happened lately, that Alice had begun to think that very few +things indeed were really impossible. + + There seemed to be no use in waiting by the little door, so she +went back to the table, half hoping she might find another key on +it, or at any rate a book of rules for shutting people up like +telescopes: this time she found a little bottle on it, (`which +certainly was not here before,' said Alice,) and round the neck +of the bottle was a paper label, with the words `DRINK ME' +beautifully printed on it in large letters. + + It was all very well to say `Drink me,' but the wise little +Alice was not going to do THAT in a hurry. `No, I'll look +first,' she said, `and see whether it's marked "poison" or not'; +for she had read several nice little histories about children who +had got burnt, and eaten up by wild beasts and other unpleasant +things, all because they WOULD not remember the simple rules +their friends had taught them: such as, that a red-hot poker +will burn you if you hold it too long; and that if you cut your +finger VERY deeply with a knife, it usually bleeds; and she had +never forgotten that, if you drink much from a bottle marked +`poison,' it is almost certain to disagree with you, sooner or +later. + + However, this bottle was NOT marked `poison,' so Alice ventured +to taste it, and finding it very nice, (it had, in fact, a sort +of mixed flavour of cherry-tart, custard, pine-apple, roast +turkey, toffee, and hot buttered toast,) she very soon finished +it off. + + * * * * * * * + + * * * * * * + + * * * * * * * + + `What a curious feeling!' said Alice; `I must be shutting up +like a telescope.' + + And so it was indeed: she was now only ten inches high, and +her face brightened up at the thought that she was now the right +size for going though the little door into that lovely garden. +First, however, she waited for a few minutes to see if she was +going to shrink any further: she felt a little nervous about +this; `for it might end, you know,' said Alice to herself, `in my +going out altogether, like a candle. I wonder what I should be +like then?' And she tried to fancy what the flame of a candle is +like after the candle is blown out, for she could not remember +ever having seen such a thing. + + After a while, finding that nothing more happened, she decided +on going into the garden at once; but, alas for poor Alice! when +she got to the door, she found he had forgotten the little golden +key, and when she went back to the table for it, she found she +could not possibly reach it: she could see it quite plainly +through the glass, and she tried her best to climb up one of the +legs of the table, but it was too slippery; and when she had +tired herself out with trying, the poor little thing sat down and +cried. + + `Come, there's no use in crying like that!' said Alice to +herself, rather sharply; `I advise you to leave off this minute!' +She generally gave herself very good advice, (though she very +seldom followed it), and sometimes she scolded herself so +severely as to bring tears into her eyes; and once she remembered +trying to box her own ears for having cheated herself in a game +of croquet she was playing against herself, for this curious +child was very fond of pretending to be two people. `But it's no +use now,' thought poor Alice, `to pretend to be two people! Why, +there's hardly enough of me left to make ONE respectable +person!' + + Soon her eye fell on a little glass box that was lying under +the table: she opened it, and found in it a very small cake, on +which the words `EAT ME' were beautifully marked in currants. +`Well, I'll eat it,' said Alice, `and if it makes me grow larger, +I can reach the key; and if it makes me grow smaller, I can creep +under the door; so either way I'll get into the garden, and I +don't care which happens!' + + She ate a little bit, and said anxiously to herself, `Which +way? Which way?', holding her hand on the top of her head to +feel which way it was growing, and she was quite surprised to +find that she remained the same size: to be sure, this generally +happens when one eats cake, but Alice had got so much into the +way of expecting nothing but out-of-the-way things to happen, +that it seemed quite dull and stupid for life to go on in the +common way. + + So she set to work, and very soon finished off the cake. + + * * * * * * * + + * * * * * * + + * * * * * * * + + + + + CHAPTER II + + The Pool of Tears + + + `Curiouser and curiouser!' cried Alice (she was so much +surprised, that for the moment she quite forgot how to speak good +English); `now I'm opening out like the largest telescope that +ever was! Good-bye, feet!' (for when she looked down at her +feet, they seemed to be almost out of sight, they were getting so +far off). `Oh, my poor little feet, I wonder who will put on +your shoes and stockings for you now, dears? I'm sure _I_ shan't +be able! I shall be a great deal too far off to trouble myself +about you: you must manage the best way you can; --but I must be +kind to them,' thought Alice, `or perhaps they won't walk the +way I want to go! Let me see: I'll give them a new pair of +boots every Christmas.' + + And she went on planning to herself how she would manage it. +`They must go by the carrier,' she thought; `and how funny it'll +seem, sending presents to one's own feet! And how odd the +directions will look! + + ALICE'S RIGHT FOOT, ESQ. + HEARTHRUG, + NEAR THE FENDER, + (WITH ALICE'S LOVE). + +Oh dear, what nonsense I'm talking!' + + Just then her head struck against the roof of the hall: in +fact she was now more than nine feet high, and she at once took +up the little golden key and hurried off to the garden door. + + Poor Alice! It was as much as she could do, lying down on one +side, to look through into the garden with one eye; but to get +through was more hopeless than ever: she sat down and began to +cry again. + + `You ought to be ashamed of yourself,' said Alice, `a great +girl like you,' (she might well say this), `to go on crying in +this way! Stop this moment, I tell you!' But she went on all +the same, shedding gallons of tears, until there was a large pool +all round her, about four inches deep and reaching half down the +hall. + + After a time she heard a little pattering of feet in the +distance, and she hastily dried her eyes to see what was coming. +It was the White Rabbit returning, splendidly dressed, with a +pair of white kid gloves in one hand and a large fan in the +other: he came trotting along in a great hurry, muttering to +himself as he came, `Oh! the Duchess, the Duchess! Oh! won't she +be savage if I've kept her waiting!' Alice felt so desperate +that she was ready to ask help of any one; so, when the Rabbit +came near her, she began, in a low, timid voice, `If you please, +sir--' The Rabbit started violently, dropped the white kid +gloves and the fan, and skurried away into the darkness as hard +as he could go. + + Alice took up the fan and gloves, and, as the hall was very +hot, she kept fanning herself all the time she went on talking: +`Dear, dear! How queer everything is to-day! And yesterday +things went on just as usual. I wonder if I've been changed in +the night? Let me think: was I the same when I got up this +morning? I almost think I can remember feeling a little +different. But if I'm not the same, the next question is, Who in +the world am I? Ah, THAT'S the great puzzle!' And she began +thinking over all the children she knew that were of the same age +as herself, to see if she could have been changed for any of +them. + + `I'm sure I'm not Ada,' she said, `for her hair goes in such +long ringlets, and mine doesn't go in ringlets at all; and I'm +sure I can't be Mabel, for I know all sorts of things, and she, +oh! she knows such a very little! Besides, SHE'S she, and I'm I, +and--oh dear, how puzzling it all is! I'll try if I know all the +things I used to know. Let me see: four times five is twelve, +and four times six is thirteen, and four times seven is--oh dear! +I shall never get to twenty at that rate! However, the +Multiplication Table doesn't signify: let's try Geography. +London is the capital of Paris, and Paris is the capital of Rome, +and Rome--no, THAT'S all wrong, I'm certain! I must have been +changed for Mabel! I'll try and say "How doth the little--"' +and she crossed her hands on her lap as if she were saying lessons, +and began to repeat it, but her voice sounded hoarse and +strange, and the words did not come the same as they used to do:-- + + `How doth the little crocodile + Improve his shining tail, + And pour the waters of the Nile + On every golden scale! + + `How cheerfully he seems to grin, + How neatly spread his claws, + And welcome little fishes in + With gently smiling jaws!' + + `I'm sure those are not the right words,' said poor Alice, and +her eyes filled with tears again as she went on, `I must be Mabel +after all, and I shall have to go and live in that poky little +house, and have next to no toys to play with, and oh! ever so +many lessons to learn! No, I've made up my mind about it; if I'm +Mabel, I'll stay down here! It'll be no use their putting their +heads down and saying "Come up again, dear!" I shall only look +up and say "Who am I then? Tell me that first, and then, if I +like being that person, I'll come up: if not, I'll stay down +here till I'm somebody else"--but, oh dear!' cried Alice, with a +sudden burst of tears, `I do wish they WOULD put their heads +down! I am so VERY tired of being all alone here!' + + As she said this she looked down at her hands, and was +surprised to see that she had put on one of the Rabbit's little +white kid gloves while she was talking. `How CAN I have done +that?' she thought. `I must be growing small again.' She got up +and went to the table to measure herself by it, and found that, +as nearly as she could guess, she was now about two feet high, +and was going on shrinking rapidly: she soon found out that the +cause of this was the fan she was holding, and she dropped it +hastily, just in time to avoid shrinking away altogether. + +`That WAS a narrow escape!' said Alice, a good deal frightened at +the sudden change, but very glad to find herself still in +existence; `and now for the garden!' and she ran with all speed +back to the little door: but, alas! the little door was shut +again, and the little golden key was lying on the glass table as +before, `and things are worse than ever,' thought the poor child, +`for I never was so small as this before, never! And I declare +it's too bad, that it is!' + + As she said these words her foot slipped, and in another +moment, splash! she was up to her chin in salt water. He first +idea was that she had somehow fallen into the sea, `and in that +case I can go back by railway,' she said to herself. (Alice had +been to the seaside once in her life, and had come to the general +conclusion, that wherever you go to on the English coast you find +a number of bathing machines in the sea, some children digging in +the sand with wooden spades, then a row of lodging houses, and +behind them a railway station.) However, she soon made out that +she was in the pool of tears which she had wept when she was nine +feet high. + + `I wish I hadn't cried so much!' said Alice, as she swam about, +trying to find her way out. `I shall be punished for it now, I +suppose, by being drowned in my own tears! That WILL be a queer +thing, to be sure! However, everything is queer to-day.' + + Just then she heard something splashing about in the pool a +little way off, and she swam nearer to make out what it was: at +first she thought it must be a walrus or hippopotamus, but then +she remembered how small she was now, and she soon made out that +it was only a mouse that had slipped in like herself. + + `Would it be of any use, now,' thought Alice, `to speak to this +mouse? Everything is so out-of-the-way down here, that I should +think very likely it can talk: at any rate, there's no harm in +trying.' So she began: `O Mouse, do you know the way out of +this pool? I am very tired of swimming about here, O Mouse!' +(Alice thought this must be the right way of speaking to a mouse: +she had never done such a thing before, but she remembered having +seen in her brother's Latin Grammar, `A mouse--of a mouse--to a +mouse--a mouse--O mouse!' The Mouse looked at her rather +inquisitively, and seemed to her to wink with one of its little +eyes, but it said nothing. + + `Perhaps it doesn't understand English,' thought Alice; `I +daresay it's a French mouse, come over with William the +Conqueror.' (For, with all her knowledge of history, Alice had +no very clear notion how long ago anything had happened.) So she +began again: `Ou est ma chatte?' which was the first sentence in +her French lesson-book. The Mouse gave a sudden leap out of the +water, and seemed to quiver all over with fright. `Oh, I beg +your pardon!' cried Alice hastily, afraid that she had hurt the +poor animal's feelings. `I quite forgot you didn't like cats.' + + `Not like cats!' cried the Mouse, in a shrill, passionate +voice. `Would YOU like cats if you were me?' + + `Well, perhaps not,' said Alice in a soothing tone: `don't be +angry about it. And yet I wish I could show you our cat Dinah: +I think you'd take a fancy to cats if you could only see her. +She is such a dear quiet thing,' Alice went on, half to herself, +as she swam lazily about in the pool, `and she sits purring so +nicely by the fire, licking her paws and washing her face--and +she is such a nice soft thing to nurse--and she's such a capital +one for catching mice--oh, I beg your pardon!' cried Alice again, +for this time the Mouse was bristling all over, and she felt +certain it must be really offended. `We won't talk about her any +more if you'd rather not.' + + `We indeed!' cried the Mouse, who was trembling down to the end +of his tail. `As if I would talk on such a subject! Our family +always HATED cats: nasty, low, vulgar things! Don't let me hear +the name again!' + + `I won't indeed!' said Alice, in a great hurry to change the +subject of conversation. `Are you--are you fond--of--of dogs?' +The Mouse did not answer, so Alice went on eagerly: `There is +such a nice little dog near our house I should like to show you! +A little bright-eyed terrier, you know, with oh, such long curly +brown hair! And it'll fetch things when you throw them, and +it'll sit up and beg for its dinner, and all sorts of things--I +can't remember half of them--and it belongs to a farmer, you +know, and he says it's so useful, it's worth a hundred pounds! +He says it kills all the rats and--oh dear!' cried Alice in a +sorrowful tone, `I'm afraid I've offended it again!' For the +Mouse was swimming away from her as hard as it could go, and +making quite a commotion in the pool as it went. + + So she called softly after it, `Mouse dear! Do come back +again, and we won't talk about cats or dogs either, if you don't +like them!' When the Mouse heard this, it turned round and swam +slowly back to her: its face was quite pale (with passion, Alice +thought), and it said in a low trembling voice, `Let us get to +the shore, and then I'll tell you my history, and you'll +understand why it is I hate cats and dogs.' + + It was high time to go, for the pool was getting quite crowded +with the birds and animals that had fallen into it: there were a +Duck and a Dodo, a Lory and an Eaglet, and several other curious +creatures. Alice led the way, and the whole party swam to the +shore. + + + + CHAPTER III + + A Caucus-Race and a Long Tale + + + They were indeed a queer-looking party that assembled on the +bank--the birds with draggled feathers, the animals with their +fur clinging close to them, and all dripping wet, cross, and +uncomfortable. + + The first question of course was, how to get dry again: they +had a consultation about this, and after a few minutes it seemed +quite natural to Alice to find herself talking familiarly with +them, as if she had known them all her life. Indeed, she had +quite a long argument with the Lory, who at last turned sulky, +and would only say, `I am older than you, and must know better'; +and this Alice would not allow without knowing how old it was, +and, as the Lory positively refused to tell its age, there was no +more to be said. + + At last the Mouse, who seemed to be a person of authority among +them, called out, `Sit down, all of you, and listen to me! I'LL +soon make you dry enough!' They all sat down at once, in a large +ring, with the Mouse in the middle. Alice kept her eyes +anxiously fixed on it, for she felt sure she would catch a bad +cold if she did not get dry very soon. + + `Ahem!' said the Mouse with an important air, `are you all ready? +This is the driest thing I know. Silence all round, if you please! +"William the Conqueror, whose cause was favoured by the pope, was +soon submitted to by the English, who wanted leaders, and had been +of late much accustomed to usurpation and conquest. Edwin and +Morcar, the earls of Mercia and Northumbria--"' + + `Ugh!' said the Lory, with a shiver. + + `I beg your pardon!' said the Mouse, frowning, but very +politely: `Did you speak?' + + `Not I!' said the Lory hastily. + + `I thought you did,' said the Mouse. `--I proceed. "Edwin and +Morcar, the earls of Mercia and Northumbria, declared for him: +and even Stigand, the patriotic archbishop of Canterbury, found +it advisable--"' + + `Found WHAT?' said the Duck. + + `Found IT,' the Mouse replied rather crossly: `of course you +know what "it" means.' + + `I know what "it" means well enough, when I find a thing,' said +the Duck: `it's generally a frog or a worm. The question is, +what did the archbishop find?' + + The Mouse did not notice this question, but hurriedly went on, +`"--found it advisable to go with Edgar Atheling to meet William +and offer him the crown. William's conduct at first was +moderate. But the insolence of his Normans--" How are you +getting on now, my dear?' it continued, turning to Alice as it +spoke. + + `As wet as ever,' said Alice in a melancholy tone: `it doesn't +seem to dry me at all.' + + `In that case,' said the Dodo solemnly, rising to its feet, `I +move that the meeting adjourn, for the immediate adoption of more +energetic remedies--' + + `Speak English!' said the Eaglet. `I don't know the meaning of +half those long words, and, what's more, I don't believe you do +either!' And the Eaglet bent down its head to hide a smile: +some of the other birds tittered audibly. + + `What I was going to say,' said the Dodo in an offended tone, +`was, that the best thing to get us dry would be a Caucus-race.' + + `What IS a Caucus-race?' said Alice; not that she wanted much +to know, but the Dodo had paused as if it thought that SOMEBODY +ought to speak, and no one else seemed inclined to say anything. + + `Why,' said the Dodo, `the best way to explain it is to do it.' +(And, as you might like to try the thing yourself, some winter +day, I will tell you how the Dodo managed it.) + + First it marked out a race-course, in a sort of circle, (`the +exact shape doesn't matter,' it said,) and then all the party +were placed along the course, here and there. There was no `One, +two, three, and away,' but they began running when they liked, +and left off when they liked, so that it was not easy to know +when the race was over. However, when they had been running half +an hour or so, and were quite dry again, the Dodo suddenly called +out `The race is over!' and they all crowded round it, panting, +and asking, `But who has won?' + + This question the Dodo could not answer without a great deal of +thought, and it sat for a long time with one finger pressed upon +its forehead (the position in which you usually see Shakespeare, +in the pictures of him), while the rest waited in silence. At +last the Dodo said, `EVERYBODY has won, and all must have +prizes.' + + `But who is to give the prizes?' quite a chorus of voices +asked. + + `Why, SHE, of course,' said the Dodo, pointing to Alice with +one finger; and the whole party at once crowded round her, +calling out in a confused way, `Prizes! Prizes!' + + Alice had no idea what to do, and in despair she put her hand +in her pocket, and pulled out a box of comfits, (luckily the salt +water had not got into it), and handed them round as prizes. +There was exactly one a-piece all round. + + `But she must have a prize herself, you know,' said the Mouse. + + `Of course,' the Dodo replied very gravely. `What else have +you got in your pocket?' he went on, turning to Alice. + + `Only a thimble,' said Alice sadly. + + `Hand it over here,' said the Dodo. + + Then they all crowded round her once more, while the Dodo +solemnly presented the thimble, saying `We beg your acceptance of +this elegant thimble'; and, when it had finished this short +speech, they all cheered. + + Alice thought the whole thing very absurd, but they all looked +so grave that she did not dare to laugh; and, as she could not +think of anything to say, she simply bowed, and took the thimble, +looking as solemn as she could. + + The next thing was to eat the comfits: this caused some noise +and confusion, as the large birds complained that they could not +taste theirs, and the small ones choked and had to be patted on +the back. However, it was over at last, and they sat down again +in a ring, and begged the Mouse to tell them something more. + + `You promised to tell me your history, you know,' said Alice, +`and why it is you hate--C and D,' she added in a whisper, half +afraid that it would be offended again. + + `Mine is a long and a sad tale!' said the Mouse, turning to +Alice, and sighing. + + `It IS a long tail, certainly,' said Alice, looking down with +wonder at the Mouse's tail; `but why do you call it sad?' And +she kept on puzzling about it while the Mouse was speaking, so +that her idea of the tale was something like this:-- + + `Fury said to a + mouse, That he + met in the + house, + "Let us + both go to + law: I will + prosecute + YOU. --Come, + I'll take no + denial; We + must have a + trial: For + really this + morning I've + nothing + to do." + Said the + mouse to the + cur, "Such + a trial, + dear Sir, + With + no jury + or judge, + would be + wasting + our + breath." + "I'll be + judge, I'll + be jury," + Said + cunning + old Fury: + "I'll + try the + whole + cause, + and + condemn + you + to + death."' + + + `You are not attending!' said the Mouse to Alice severely. +`What are you thinking of?' + + `I beg your pardon,' said Alice very humbly: `you had got to +the fifth bend, I think?' + + `I had NOT!' cried the Mouse, sharply and very angrily. + + `A knot!' said Alice, always ready to make herself useful, and +looking anxiously about her. `Oh, do let me help to undo it!' + + `I shall do nothing of the sort,' said the Mouse, getting up +and walking away. `You insult me by talking such nonsense!' + + `I didn't mean it!' pleaded poor Alice. `But you're so easily +offended, you know!' + + The Mouse only growled in reply. + + `Please come back and finish your story!' Alice called after +it; and the others all joined in chorus, `Yes, please do!' but +the Mouse only shook its head impatiently, and walked a little +quicker. + + `What a pity it wouldn't stay!' sighed the Lory, as soon as it +was quite out of sight; and an old Crab took the opportunity of +saying to her daughter `Ah, my dear! Let this be a lesson to you +never to lose YOUR temper!' `Hold your tongue, Ma!' said the +young Crab, a little snappishly. `You're enough to try the +patience of an oyster!' + + `I wish I had our Dinah here, I know I do!' said Alice aloud, +addressing nobody in particular. `She'd soon fetch it back!' + + `And who is Dinah, if I might venture to ask the question?' +said the Lory. + + Alice replied eagerly, for she was always ready to talk about +her pet: `Dinah's our cat. And she's such a capital one for +catching mice you can't think! And oh, I wish you could see her +after the birds! Why, she'll eat a little bird as soon as look +at it!' + + This speech caused a remarkable sensation among the party. +Some of the birds hurried off at once: one the old Magpie began +wrapping itself up very carefully, remarking, `I really must be +getting home; the night-air doesn't suit my throat!' and a Canary +called out in a trembling voice to its children, `Come away, my +dears! It's high time you were all in bed!' On various pretexts +they all moved off, and Alice was soon left alone. + + `I wish I hadn't mentioned Dinah!' she said to herself in a +melancholy tone. `Nobody seems to like her, down here, and I'm +sure she's the best cat in the world! Oh, my dear Dinah! I +wonder if I shall ever see you any more!' And here poor Alice +began to cry again, for she felt very lonely and low-spirited. +In a little while, however, she again heard a little pattering of +footsteps in the distance, and she looked up eagerly, half hoping +that the Mouse had changed his mind, and was coming back to +finish his story. + + + + CHAPTER IV + + The Rabbit Sends in a Little Bill + + + It was the White Rabbit, trotting slowly back again, and +looking anxiously about as it went, as if it had lost something; +and she heard it muttering to itself `The Duchess! The Duchess! +Oh my dear paws! Oh my fur and whiskers! She'll get me +executed, as sure as ferrets are ferrets! Where CAN I have +dropped them, I wonder?' Alice guessed in a moment that it was +looking for the fan and the pair of white kid gloves, and she +very good-naturedly began hunting about for them, but they were +nowhere to be seen--everything seemed to have changed since her +swim in the pool, and the great hall, with the glass table and +the little door, had vanished completely. + + Very soon the Rabbit noticed Alice, as she went hunting about, +and called out to her in an angry tone, `Why, Mary Ann, what ARE +you doing out here? Run home this moment, and fetch me a pair of +gloves and a fan! Quick, now!' And Alice was so much frightened +that she ran off at once in the direction it pointed to, without +trying to explain the mistake it had made. + + `He took me for his housemaid,' she said to herself as she ran. +`How surprised he'll be when he finds out who I am! But I'd +better take him his fan and gloves--that is, if I can find them.' +As she said this, she came upon a neat little house, on the door +of which was a bright brass plate with the name `W. RABBIT' +engraved upon it. She went in without knocking, and hurried +upstairs, in great fear lest she should meet the real Mary Ann, +and be turned out of the house before she had found the fan and +gloves. + + `How queer it seems,' Alice said to herself, `to be going +messages for a rabbit! I suppose Dinah'll be sending me on +messages next!' And she began fancying the sort of thing that +would happen: `"Miss Alice! Come here directly, and get ready +for your walk!" "Coming in a minute, nurse! But I've got to see +that the mouse doesn't get out." Only I don't think,' Alice went +on, `that they'd let Dinah stop in the house if it began ordering +people about like that!' + + By this time she had found her way into a tidy little room with +a table in the window, and on it (as she had hoped) a fan and two +or three pairs of tiny white kid gloves: she took up the fan and +a pair of the gloves, and was just going to leave the room, when +her eye fell upon a little bottle that stood near the looking- +glass. There was no label this time with the words `DRINK ME,' +but nevertheless she uncorked it and put it to her lips. `I know +SOMETHING interesting is sure to happen,' she said to herself, +`whenever I eat or drink anything; so I'll just see what this +bottle does. I do hope it'll make me grow large again, for +really I'm quite tired of being such a tiny little thing!' + + It did so indeed, and much sooner than she had expected: +before she had drunk half the bottle, she found her head pressing +against the ceiling, and had to stoop to save her neck from being +broken. She hastily put down the bottle, saying to herself +`That's quite enough--I hope I shan't grow any more--As it is, I +can't get out at the door--I do wish I hadn't drunk quite so +much!' + + Alas! it was too late to wish that! She went on growing, and +growing, and very soon had to kneel down on the floor: in +another minute there was not even room for this, and she tried +the effect of lying down with one elbow against the door, and the +other arm curled round her head. Still she went on growing, and, +as a last resource, she put one arm out of the window, and one +foot up the chimney, and said to herself `Now I can do no more, +whatever happens. What WILL become of me?' + + Luckily for Alice, the little magic bottle had now had its full +effect, and she grew no larger: still it was very uncomfortable, +and, as there seemed to be no sort of chance of her ever getting +out of the room again, no wonder she felt unhappy. + + `It was much pleasanter at home,' thought poor Alice, `when one +wasn't always growing larger and smaller, and being ordered about +by mice and rabbits. I almost wish I hadn't gone down that +rabbit-hole--and yet--and yet--it's rather curious, you know, +this sort of life! I do wonder what CAN have happened to me! +When I used to read fairy-tales, I fancied that kind of thing +never happened, and now here I am in the middle of one! There +ought to be a book written about me, that there ought! And when +I grow up, I'll write one--but I'm grown up now,' she added in a +sorrowful tone; `at least there's no room to grow up any more +HERE.' + + `But then,' thought Alice, `shall I NEVER get any older than I +am now? That'll be a comfort, one way--never to be an old woman- +-but then--always to have lessons to learn! Oh, I shouldn't like +THAT!' + + `Oh, you foolish Alice!' she answered herself. `How can you +learn lessons in here? Why, there's hardly room for YOU, and no +room at all for any lesson-books!' + + And so she went on, taking first one side and then the other, +and making quite a conversation of it altogether; but after a few +minutes she heard a voice outside, and stopped to listen. + + `Mary Ann! Mary Ann!' said the voice. `Fetch me my gloves +this moment!' Then came a little pattering of feet on the +stairs. Alice knew it was the Rabbit coming to look for her, and +she trembled till she shook the house, quite forgetting that she +was now about a thousand times as large as the Rabbit, and had no +reason to be afraid of it. + + Presently the Rabbit came up to the door, and tried to open it; +but, as the door opened inwards, and Alice's elbow was pressed +hard against it, that attempt proved a failure. Alice heard it +say to itself `Then I'll go round and get in at the window.' + + `THAT you won't' thought Alice, and, after waiting till she +fancied she heard the Rabbit just under the window, she suddenly +spread out her hand, and made a snatch in the air. She did not +get hold of anything, but she heard a little shriek and a fall, +and a crash of broken glass, from which she concluded that it was +just possible it had fallen into a cucumber-frame, or something +of the sort. + + Next came an angry voice--the Rabbit's--`Pat! Pat! Where are +you?' And then a voice she had never heard before, `Sure then +I'm here! Digging for apples, yer honour!' + + `Digging for apples, indeed!' said the Rabbit angrily. `Here! +Come and help me out of THIS!' (Sounds of more broken glass.) + + `Now tell me, Pat, what's that in the window?' + + `Sure, it's an arm, yer honour!' (He pronounced it `arrum.') + + `An arm, you goose! Who ever saw one that size? Why, it +fills the whole window!' + + `Sure, it does, yer honour: but it's an arm for all that.' + + `Well, it's got no business there, at any rate: go and take it +away!' + + There was a long silence after this, and Alice could only hear +whispers now and then; such as, `Sure, I don't like it, yer +honour, at all, at all!' `Do as I tell you, you coward!' and at +last she spread out her hand again, and made another snatch in +the air. This time there were TWO little shrieks, and more +sounds of broken glass. `What a number of cucumber-frames there +must be!' thought Alice. `I wonder what they'll do next! As for +pulling me out of the window, I only wish they COULD! I'm sure I +don't want to stay in here any longer!' + + She waited for some time without hearing anything more: at +last came a rumbling of little cartwheels, and the sound of a +good many voice all talking together: she made out the words: +`Where's the other ladder?--Why, I hadn't to bring but one; +Bill's got the other--Bill! fetch it here, lad!--Here, put 'em up +at this corner--No, tie 'em together first--they don't reach half +high enough yet--Oh! they'll do well enough; don't be particular- +-Here, Bill! catch hold of this rope--Will the roof bear?--Mind +that loose slate--Oh, it's coming down! Heads below!' (a loud +crash)--`Now, who did that?--It was Bill, I fancy--Who's to go +down the chimney?--Nay, I shan't! YOU do it!--That I won't, +then!--Bill's to go down--Here, Bill! the master says you're to +go down the chimney!' + + `Oh! So Bill's got to come down the chimney, has he?' said +Alice to herself. `Shy, they seem to put everything upon Bill! +I wouldn't be in Bill's place for a good deal: this fireplace is +narrow, to be sure; but I THINK I can kick a little!' + + She drew her foot as far down the chimney as she could, and +waited till she heard a little animal (she couldn't guess of what +sort it was) scratching and scrambling about in the chimney close +above her: then, saying to herself `This is Bill,' she gave one +sharp kick, and waited to see what would happen next. + + The first thing she heard was a general chorus of `There goes +Bill!' then the Rabbit's voice along--`Catch him, you by the +hedge!' then silence, and then another confusion of voices--`Hold +up his head--Brandy now--Don't choke him--How was it, old fellow? +What happened to you? Tell us all about it!' + + Last came a little feeble, squeaking voice, (`That's Bill,' +thought Alice,) `Well, I hardly know--No more, thank ye; I'm +better now--but I'm a deal too flustered to tell you--all I know +is, something comes at me like a Jack-in-the-box, and up I goes +like a sky-rocket!' + + `So you did, old fellow!' said the others. + + `We must burn the house down!' said the Rabbit's voice; and +Alice called out as loud as she could, `If you do. I'll set +Dinah at you!' + + There was a dead silence instantly, and Alice thought to +herself, `I wonder what they WILL do next! If they had any +sense, they'd take the roof off.' After a minute or two, they +began moving about again, and Alice heard the Rabbit say, `A +barrowful will do, to begin with.' + + `A barrowful of WHAT?' thought Alice; but she had not long to +doubt, for the next moment a shower of little pebbles came +rattling in at the window, and some of them hit her in the face. +`I'll put a stop to this,' she said to herself, and shouted out, +`You'd better not do that again!' which produced another dead +silence. + + Alice noticed with some surprise that the pebbles were all +turning into little cakes as they lay on the floor, and a bright +idea came into her head. `If I eat one of these cakes,' she +thought, `it's sure to make SOME change in my size; and as it +can't possibly make me larger, it must make me smaller, I +suppose.' + + So she swallowed one of the cakes, and was delighted to find +that she began shrinking directly. As soon as she was small +enough to get through the door, she ran out of the house, and +found quite a crowd of little animals and birds waiting outside. +The poor little Lizard, Bill, was in the middle, being held up by +two guinea-pigs, who were giving it something out of a bottle. +They all made a rush at Alice the moment she appeared; but she +ran off as hard as she could, and soon found herself safe in a +thick wood. + + `The first thing I've got to do,' said Alice to herself, as she +wandered about in the wood, `is to grow to my right size again; +and the second thing is to find my way into that lovely garden. +I think that will be the best plan.' + + It sounded an excellent plan, no doubt, and very neatly and +simply arranged; the only difficulty was, that she had not the +smallest idea how to set about it; and while she was peering +about anxiously among the trees, a little sharp bark just over +her head made her look up in a great hurry. + + An enormous puppy was looking down at her with large round +eyes, and feebly stretching out one paw, trying to touch her. +`Poor little thing!' said Alice, in a coaxing tone, and she tried +hard to whistle to it; but she was terribly frightened all the +time at the thought that it might be hungry, in which case it +would be very likely to eat her up in spite of all her coaxing. + + Hardly knowing what she did, she picked up a little bit of +stick, and held it out to the puppy; whereupon the puppy jumped +into the air off all its feet at once, with a yelp of delight, +and rushed at the stick, and made believe to worry it; then Alice +dodged behind a great thistle, to keep herself from being run +over; and the moment she appeared on the other side, the puppy +made another rush at the stick, and tumbled head over heels in +its hurry to get hold of it; then Alice, thinking it was very +like having a game of play with a cart-horse, and expecting every +moment to be trampled under its feet, ran round the thistle +again; then the puppy began a series of short charges at the +stick, running a very little way forwards each time and a long +way back, and barking hoarsely all the while, till at last it sat +down a good way off, panting, with its tongue hanging out of its +mouth, and its great eyes half shut. + + This seemed to Alice a good opportunity for making her escape; +so she set off at once, and ran till she was quite tired and out +of breath, and till the puppy's bark sounded quite faint in the +distance. + + `And yet what a dear little puppy it was!' said Alice, as she +leant against a buttercup to rest herself, and fanned herself +with one of the leaves: `I should have liked teaching it tricks +very much, if--if I'd only been the right size to do it! Oh +dear! I'd nearly forgotten that I've got to grow up again! Let +me see--how IS it to be managed? I suppose I ought to eat or +drink something or other; but the great question is, what?' + + The great question certainly was, what? Alice looked all round +her at the flowers and the blades of grass, but she did not see +anything that looked like the right thing to eat or drink under +the circumstances. There was a large mushroom growing near her, +about the same height as herself; and when she had looked under +it, and on both sides of it, and behind it, it occurred to her +that she might as well look and see what was on the top of it. + + She stretched herself up on tiptoe, and peeped over the edge of +the mushroom, and her eyes immediately met those of a large +caterpillar, that was sitting on the top with its arms folded, +quietly smoking a long hookah, and taking not the smallest notice +of her or of anything else. + + + + CHAPTER V + + Advice from a Caterpillar + + + The Caterpillar and Alice looked at each other for some time in +silence: at last the Caterpillar took the hookah out of its +mouth, and addressed her in a languid, sleepy voice. + + `Who are YOU?' said the Caterpillar. + + This was not an encouraging opening for a conversation. Alice +replied, rather shyly, `I--I hardly know, sir, just at present-- +at least I know who I WAS when I got up this morning, but I think +I must have been changed several times since then.' + + `What do you mean by that?' said the Caterpillar sternly. +`Explain yourself!' + + `I can't explain MYSELF, I'm afraid, sir' said Alice, `because +I'm not myself, you see.' + + `I don't see,' said the Caterpillar. + + `I'm afraid I can't put it more clearly,' Alice replied very +politely, `for I can't understand it myself to begin with; and +being so many different sizes in a day is very confusing.' + + `It isn't,' said the Caterpillar. + + `Well, perhaps you haven't found it so yet,' said Alice; `but +when you have to turn into a chrysalis--you will some day, you +know--and then after that into a butterfly, I should think you'll +feel it a little queer, won't you?' + + `Not a bit,' said the Caterpillar. + + `Well, perhaps your feelings may be different,' said Alice; +`all I know is, it would feel very queer to ME.' + + `You!' said the Caterpillar contemptuously. `Who are YOU?' + + Which brought them back again to the beginning of the +conversation. Alice felt a little irritated at the Caterpillar's +making such VERY short remarks, and she drew herself up and said, +very gravely, `I think, you ought to tell me who YOU are, first.' + + `Why?' said the Caterpillar. + + Here was another puzzling question; and as Alice could not +think of any good reason, and as the Caterpillar seemed to be in +a VERY unpleasant state of mind, she turned away. + + `Come back!' the Caterpillar called after her. `I've something +important to say!' + + This sounded promising, certainly: Alice turned and came back +again. + + `Keep your temper,' said the Caterpillar. + + `Is that all?' said Alice, swallowing down her anger as well as +she could. + + `No,' said the Caterpillar. + + Alice thought she might as well wait, as she had nothing else +to do, and perhaps after all it might tell her something worth +hearing. For some minutes it puffed away without speaking, but +at last it unfolded its arms, took the hookah out of its mouth +again, and said, `So you think you're changed, do you?' + + `I'm afraid I am, sir,' said Alice; `I can't remember things as +I used--and I don't keep the same size for ten minutes together!' + + `Can't remember WHAT things?' said the Caterpillar. + + `Well, I've tried to say "HOW DOTH THE LITTLE BUSY BEE," but it +all came different!' Alice replied in a very melancholy voice. + + `Repeat, "YOU ARE OLD, FATHER WILLIAM,"' said the Caterpillar. + + Alice folded her hands, and began:-- + + `You are old, Father William,' the young man said, + `And your hair has become very white; + And yet you incessantly stand on your head-- + Do you think, at your age, it is right?' + + `In my youth,' Father William replied to his son, + `I feared it might injure the brain; + But, now that I'm perfectly sure I have none, + Why, I do it again and again.' + + `You are old,' said the youth, `as I mentioned before, + And have grown most uncommonly fat; + Yet you turned a back-somersault in at the door-- + Pray, what is the reason of that?' + + `In my youth,' said the sage, as he shook his grey locks, + `I kept all my limbs very supple + By the use of this ointment--one shilling the box-- + Allow me to sell you a couple?' + + `You are old,' said the youth, `and your jaws are too weak + For anything tougher than suet; + Yet you finished the goose, with the bones and the beak-- + Pray how did you manage to do it?' + + `In my youth,' said his father, `I took to the law, + And argued each case with my wife; + And the muscular strength, which it gave to my jaw, + Has lasted the rest of my life.' + + `You are old,' said the youth, `one would hardly suppose + That your eye was as steady as ever; + Yet you balanced an eel on the end of your nose-- + What made you so awfully clever?' + + `I have answered three questions, and that is enough,' + Said his father; `don't give yourself airs! + Do you think I can listen all day to such stuff? + Be off, or I'll kick you down stairs!' + + + `That is not said right,' said the Caterpillar. + + `Not QUITE right, I'm afraid,' said Alice, timidly; `some of the +words have got altered.' + + `It is wrong from beginning to end,' said the Caterpillar +decidedly, and there was silence for some minutes. + + The Caterpillar was the first to speak. + + `What size do you want to be?' it asked. + + `Oh, I'm not particular as to size,' Alice hastily replied; +`only one doesn't like changing so often, you know.' + + `I DON'T know,' said the Caterpillar. + + Alice said nothing: she had never been so much contradicted in +her life before, and she felt that she was losing her temper. + + `Are you content now?' said the Caterpillar. + + `Well, I should like to be a LITTLE larger, sir, if you +wouldn't mind,' said Alice: `three inches is such a wretched +height to be.' + + `It is a very good height indeed!' said the Caterpillar +angrily, rearing itself upright as it spoke (it was exactly three +inches high). + + `But I'm not used to it!' pleaded poor Alice in a piteous tone. +And she thought of herself, `I wish the creatures wouldn't be so +easily offended!' + + `You'll get used to it in time,' said the Caterpillar; and it +put the hookah into its mouth and began smoking again. + + This time Alice waited patiently until it chose to speak again. +In a minute or two the Caterpillar took the hookah out of its +mouth and yawned once or twice, and shook itself. Then it got +down off the mushroom, and crawled away in the grass, merely +remarking as it went, `One side will make you grow taller, and +the other side will make you grow shorter.' + + `One side of WHAT? The other side of WHAT?' thought Alice to +herself. + + `Of the mushroom,' said the Caterpillar, just as if she had +asked it aloud; and in another moment it was out of sight. + + Alice remained looking thoughtfully at the mushroom for a +minute, trying to make out which were the two sides of it; and as +it was perfectly round, she found this a very difficult question. +However, at last she stretched her arms round it as far as they +would go, and broke off a bit of the edge with each hand. + + `And now which is which?' she said to herself, and nibbled a +little of the right-hand bit to try the effect: the next moment +she felt a violent blow underneath her chin: it had struck her +foot! + + She was a good deal frightened by this very sudden change, but +she felt that there was no time to be lost, as she was shrinking +rapidly; so she set to work at once to eat some of the other bit. +Her chin was pressed so closely against her foot, that there was +hardly room to open her mouth; but she did it at last, and +managed to swallow a morsel of the lefthand bit. + + + * * * * * * * + + * * * * * * + + * * * * * * * + + `Come, my head's free at last!' said Alice in a tone of +delight, which changed into alarm in another moment, when she +found that her shoulders were nowhere to be found: all she could +see, when she looked down, was an immense length of neck, which +seemed to rise like a stalk out of a sea of green leaves that lay +far below her. + + `What CAN all that green stuff be?' said Alice. `And where +HAVE my shoulders got to? And oh, my poor hands, how is it I +can't see you?' She was moving them about as she spoke, but no +result seemed to follow, except a little shaking among the +distant green leaves. + + As there seemed to be no chance of getting her hands up to her +head, she tried to get her head down to them, and was delighted +to find that her neck would bend about easily in any direction, +like a serpent. She had just succeeded in curving it down into a +graceful zigzag, and was going to dive in among the leaves, which +she found to be nothing but the tops of the trees under which she +had been wandering, when a sharp hiss made her draw back in a +hurry: a large pigeon had flown into her face, and was beating +her violently with its wings. + + `Serpent!' screamed the Pigeon. + + `I'm NOT a serpent!' said Alice indignantly. `Let me alone!' + + `Serpent, I say again!' repeated the Pigeon, but in a more +subdued tone, and added with a kind of sob, `I've tried every +way, and nothing seems to suit them!' + + `I haven't the least idea what you're talking about,' said +Alice. + + `I've tried the roots of trees, and I've tried banks, and I've +tried hedges,' the Pigeon went on, without attending to her; `but +those serpents! There's no pleasing them!' + + Alice was more and more puzzled, but she thought there was no +use in saying anything more till the Pigeon had finished. + + `As if it wasn't trouble enough hatching the eggs,' said the +Pigeon; `but I must be on the look-out for serpents night and +day! Why, I haven't had a wink of sleep these three weeks!' + + `I'm very sorry you've been annoyed,' said Alice, who was +beginning to see its meaning. + + `And just as I'd taken the highest tree in the wood,' continued +the Pigeon, raising its voice to a shriek, `and just as I was +thinking I should be free of them at last, they must needs come +wriggling down from the sky! Ugh, Serpent!' + + `But I'm NOT a serpent, I tell you!' said Alice. `I'm a--I'm +a--' + + `Well! WHAT are you?' said the Pigeon. `I can see you're +trying to invent something!' + + `I--I'm a little girl,' said Alice, rather doubtfully, as she +remembered the number of changes she had gone through that day. + + `A likely story indeed!' said the Pigeon in a tone of the +deepest contempt. `I've seen a good many little girls in my +time, but never ONE with such a neck as that! No, no! You're a +serpent; and there's no use denying it. I suppose you'll be +telling me next that you never tasted an egg!' + + `I HAVE tasted eggs, certainly,' said Alice, who was a very +truthful child; `but little girls eat eggs quite as much as +serpents do, you know.' + + `I don't believe it,' said the Pigeon; `but if they do, why +then they're a kind of serpent, that's all I can say.' + + This was such a new idea to Alice, that she was quite silent +for a minute or two, which gave the Pigeon the opportunity of +adding, `You're looking for eggs, I know THAT well enough; and +what does it matter to me whether you're a little girl or a +serpent?' + + `It matters a good deal to ME,' said Alice hastily; `but I'm +not looking for eggs, as it happens; and if I was, I shouldn't +want YOURS: I don't like them raw.' + + `Well, be off, then!' said the Pigeon in a sulky tone, as it +settled down again into its nest. Alice crouched down among the +trees as well as she could, for her neck kept getting entangled +among the branches, and every now and then she had to stop and +untwist it. After a while she remembered that she still held the +pieces of mushroom in her hands, and she set to work very +carefully, nibbling first at one and then at the other, and +growing sometimes taller and sometimes shorter, until she had +succeeded in bringing herself down to her usual height. + + It was so long since she had been anything near the right size, +that it felt quite strange at first; but she got used to it in a +few minutes, and began talking to herself, as usual. `Come, +there's half my plan done now! How puzzling all these changes +are! I'm never sure what I'm going to be, from one minute to +another! However, I've got back to my right size: the next +thing is, to get into that beautiful garden--how IS that to be +done, I wonder?' As she said this, she came suddenly upon an +open place, with a little house in it about four feet high. +`Whoever lives there,' thought Alice, `it'll never do to come +upon them THIS size: why, I should frighten them out of their +wits!' So she began nibbling at the righthand bit again, and did +not venture to go near the house till she had brought herself +down to nine inches high. + + + + CHAPTER VI + + Pig and Pepper + + + For a minute or two she stood looking at the house, and +wondering what to do next, when suddenly a footman in livery came +running out of the wood--(she considered him to be a footman +because he was in livery: otherwise, judging by his face only, +she would have called him a fish)--and rapped loudly at the door +with his knuckles. It was opened by another footman in livery, +with a round face, and large eyes like a frog; and both footmen, +Alice noticed, had powdered hair that curled all over their +heads. She felt very curious to know what it was all about, and +crept a little way out of the wood to listen. + + The Fish-Footman began by producing from under his arm a great +letter, nearly as large as himself, and this he handed over to +the other, saying, in a solemn tone, `For the Duchess. An +invitation from the Queen to play croquet.' The Frog-Footman +repeated, in the same solemn tone, only changing the order of the +words a little, `From the Queen. An invitation for the Duchess +to play croquet.' + + Then they both bowed low, and their curls got entangled +together. + + Alice laughed so much at this, that she had to run back into +the wood for fear of their hearing her; and when she next peeped +out the Fish-Footman was gone, and the other was sitting on the +ground near the door, staring stupidly up into the sky. + + Alice went timidly up to the door, and knocked. + + `There's no sort of use in knocking,' said the Footman, `and +that for two reasons. First, because I'm on the same side of the +door as you are; secondly, because they're making such a noise +inside, no one could possibly hear you.' And certainly there was +a most extraordinary noise going on within--a constant howling +and sneezing, and every now and then a great crash, as if a dish +or kettle had been broken to pieces. + + `Please, then,' said Alice, `how am I to get in?' + + `There might be some sense in your knocking,' the Footman went +on without attending to her, `if we had the door between us. For +instance, if you were INSIDE, you might knock, and I could let +you out, you know.' He was looking up into the sky all the time +he was speaking, and this Alice thought decidedly uncivil. `But +perhaps he can't help it,' she said to herself; `his eyes are so +VERY nearly at the top of his head. But at any rate he might +answer questions.--How am I to get in?' she repeated, aloud. + + `I shall sit here,' the Footman remarked, `till tomorrow--' + + At this moment the door of the house opened, and a large plate +came skimming out, straight at the Footman's head: it just +grazed his nose, and broke to pieces against one of the trees +behind him. + + `--or next day, maybe,' the Footman continued in the same tone, +exactly as if nothing had happened. + + `How am I to get in?' asked Alice again, in a louder tone. + + `ARE you to get in at all?' said the Footman. `That's the +first question, you know.' + + It was, no doubt: only Alice did not like to be told so. +`It's really dreadful,' she muttered to herself, `the way all the +creatures argue. It's enough to drive one crazy!' + + The Footman seemed to think this a good opportunity for +repeating his remark, with variations. `I shall sit here,' he +said, `on and off, for days and days.' + + `But what am I to do?' said Alice. + + `Anything you like,' said the Footman, and began whistling. + + `Oh, there's no use in talking to him,' said Alice desperately: +`he's perfectly idiotic!' And she opened the door and went in. + + The door led right into a large kitchen, which was full of +smoke from one end to the other: the Duchess was sitting on a +three-legged stool in the middle, nursing a baby; the cook was +leaning over the fire, stirring a large cauldron which seemed to +be full of soup. + + `There's certainly too much pepper in that soup!' Alice said to +herself, as well as she could for sneezing. + + There was certainly too much of it in the air. Even the +Duchess sneezed occasionally; and as for the baby, it was +sneezing and howling alternately without a moment's pause. The +only things in the kitchen that did not sneeze, were the cook, +and a large cat which was sitting on the hearth and grinning from +ear to ear. + + `Please would you tell me,' said Alice, a little timidly, for +she was not quite sure whether it was good manners for her to +speak first, `why your cat grins like that?' + + `It's a Cheshire cat,' said the Duchess, `and that's why. +Pig!' + + She said the last word with such sudden violence that Alice +quite jumped; but she saw in another moment that it was addressed +to the baby, and not to her, so she took courage, and went on +again:-- + + `I didn't know that Cheshire cats always grinned; in fact, I +didn't know that cats COULD grin.' + + `They all can,' said the Duchess; `and most of 'em do.' + + `I don't know of any that do,' Alice said very politely, +feeling quite pleased to have got into a conversation. + + `You don't know much,' said the Duchess; `and that's a fact.' + + Alice did not at all like the tone of this remark, and thought +it would be as well to introduce some other subject of +conversation. While she was trying to fix on one, the cook took +the cauldron of soup off the fire, and at once set to work +throwing everything within her reach at the Duchess and the baby +--the fire-irons came first; then followed a shower of saucepans, +plates, and dishes. The Duchess took no notice of them even when +they hit her; and the baby was howling so much already, that it +was quite impossible to say whether the blows hurt it or not. + + `Oh, PLEASE mind what you're doing!' cried Alice, jumping up +and down in an agony of terror. `Oh, there goes his PRECIOUS +nose'; as an unusually large saucepan flew close by it, and very +nearly carried it off. + + `If everybody minded their own business,' the Duchess said in a +hoarse growl, `the world would go round a deal faster than it +does.' + + `Which would NOT be an advantage,' said Alice, who felt very +glad to get an opportunity of showing off a little of her +knowledge. `Just think of what work it would make with the day +and night! You see the earth takes twenty-four hours to turn +round on its axis--' + + `Talking of axes,' said the Duchess, `chop off her head!' + + Alice glanced rather anxiously at the cook, to see if she meant +to take the hint; but the cook was busily stirring the soup, and +seemed not to be listening, so she went on again: `Twenty-four +hours, I THINK; or is it twelve? I--' + + `Oh, don't bother ME,' said the Duchess; `I never could abide +figures!' And with that she began nursing her child again, +singing a sort of lullaby to it as she did so, and giving it a +violent shake at the end of every line: + + `Speak roughly to your little boy, + And beat him when he sneezes: + He only does it to annoy, + Because he knows it teases.' + + CHORUS. + + (In which the cook and the baby joined):-- + + `Wow! wow! wow!' + + While the Duchess sang the second verse of the song, she kept +tossing the baby violently up and down, and the poor little thing +howled so, that Alice could hardly hear the words:-- + + `I speak severely to my boy, + I beat him when he sneezes; + For he can thoroughly enjoy + The pepper when he pleases!' + + CHORUS. + + `Wow! wow! wow!' + + `Here! you may nurse it a bit, if you like!' the Duchess said +to Alice, flinging the baby at her as she spoke. `I must go and +get ready to play croquet with the Queen,' and she hurried out of +the room. The cook threw a frying-pan after her as she went out, +but it just missed her. + + Alice caught the baby with some difficulty, as it was a queer- +shaped little creature, and held out its arms and legs in all +directions, `just like a star-fish,' thought Alice. The poor +little thing was snorting like a steam-engine when she caught it, +and kept doubling itself up and straightening itself out again, +so that altogether, for the first minute or two, it was as much +as she could do to hold it. + + As soon as she had made out the proper way of nursing it, +(which was to twist it up into a sort of knot, and then keep +tight hold of its right ear and left foot, so as to prevent its +undoing itself,) she carried it out into the open air. `IF I +don't take this child away with me,' thought Alice, `they're sure +to kill it in a day or two: wouldn't it be murder to leave it +behind?' She said the last words out loud, and the little thing +grunted in reply (it had left off sneezing by this time). `Don't +grunt,' said Alice; `that's not at all a proper way of expressing +yourself.' + + The baby grunted again, and Alice looked very anxiously into +its face to see what was the matter with it. There could be no +doubt that it had a VERY turn-up nose, much more like a snout +than a real nose; also its eyes were getting extremely small for +a baby: altogether Alice did not like the look of the thing at +all. `But perhaps it was only sobbing,' she thought, and looked +into its eyes again, to see if there were any tears. + + No, there were no tears. `If you're going to turn into a pig, +my dear,' said Alice, seriously, `I'll have nothing more to do +with you. Mind now!' The poor little thing sobbed again (or +grunted, it was impossible to say which), and they went on for +some while in silence. + + Alice was just beginning to think to herself, `Now, what am I +to do with this creature when I get it home?' when it grunted +again, so violently, that she looked down into its face in some +alarm. This time there could be NO mistake about it: it was +neither more nor less than a pig, and she felt that it would be +quite absurd for her to carry it further. + + So she set the little creature down, and felt quite relieved to +see it trot away quietly into the wood. `If it had grown up,' +she said to herself, `it would have made a dreadfully ugly child: +but it makes rather a handsome pig, I think.' And she began +thinking over other children she knew, who might do very well as +pigs, and was just saying to herself, `if one only knew the right +way to change them--' when she was a little startled by seeing +the Cheshire Cat sitting on a bough of a tree a few yards off. + + The Cat only grinned when it saw Alice. It looked good- +natured, she thought: still it had VERY long claws and a great +many teeth, so she felt that it ought to be treated with respect. + + `Cheshire Puss,' she began, rather timidly, as she did not at +all know whether it would like the name: however, it only +grinned a little wider. `Come, it's pleased so far,' thought +Alice, and she went on. `Would you tell me, please, which way I +ought to go from here?' + + `That depends a good deal on where you want to get to,' said +the Cat. + + `I don't much care where--' said Alice. + + `Then it doesn't matter which way you go,' said the Cat. + + `--so long as I get SOMEWHERE,' Alice added as an explanation. + + `Oh, you're sure to do that,' said the Cat, `if you only walk +long enough.' + + Alice felt that this could not be denied, so she tried another +question. `What sort of people live about here?' + + `In THAT direction,' the Cat said, waving its right paw round, +`lives a Hatter: and in THAT direction,' waving the other paw, +`lives a March Hare. Visit either you like: they're both mad.' + + `But I don't want to go among mad people,' Alice remarked. + + `Oh, you can't help that,' said the Cat: `we're all mad here. +I'm mad. You're mad.' + + `How do you know I'm mad?' said Alice. + + `You must be,' said the Cat, `or you wouldn't have come here.' + + Alice didn't think that proved it at all; however, she went on +`And how do you know that you're mad?' + + `To begin with,' said the Cat, `a dog's not mad. You grant +that?' + + `I suppose so,' said Alice. + + `Well, then,' the Cat went on, `you see, a dog growls when it's +angry, and wags its tail when it's pleased. Now I growl when I'm +pleased, and wag my tail when I'm angry. Therefore I'm mad.' + + `I call it purring, not growling,' said Alice. + + `Call it what you like,' said the Cat. `Do you play croquet +with the Queen to-day?' + + `I should like it very much,' said Alice, `but I haven't been +invited yet.' + + `You'll see me there,' said the Cat, and vanished. + + Alice was not much surprised at this, she was getting so used +to queer things happening. While she was looking at the place +where it had been, it suddenly appeared again. + + `By-the-bye, what became of the baby?' said the Cat. `I'd +nearly forgotten to ask.' + + `It turned into a pig,' Alice quietly said, just as if it had +come back in a natural way. + + `I thought it would,' said the Cat, and vanished again. + + Alice waited a little, half expecting to see it again, but it +did not appear, and after a minute or two she walked on in the +direction in which the March Hare was said to live. `I've seen +hatters before,' she said to herself; `the March Hare will be +much the most interesting, and perhaps as this is May it won't be +raving mad--at least not so mad as it was in March.' As she said +this, she looked up, and there was the Cat again, sitting on a +branch of a tree. + + `Did you say pig, or fig?' said the Cat. + + `I said pig,' replied Alice; `and I wish you wouldn't keep +appearing and vanishing so suddenly: you make one quite giddy.' + + `All right,' said the Cat; and this time it vanished quite +slowly, beginning with the end of the tail, and ending with the +grin, which remained some time after the rest of it had gone. + + `Well! I've often seen a cat without a grin,' thought Alice; +`but a grin without a cat! It's the most curious thing I ever +say in my life!' + + She had not gone much farther before she came in sight of the +house of the March Hare: she thought it must be the right house, +because the chimneys were shaped like ears and the roof was +thatched with fur. It was so large a house, that she did not +like to go nearer till she had nibbled some more of the lefthand +bit of mushroom, and raised herself to about two feet high: even +then she walked up towards it rather timidly, saying to herself +`Suppose it should be raving mad after all! I almost wish I'd +gone to see the Hatter instead!' + + + + CHAPTER VII + + A Mad Tea-Party + + + There was a table set out under a tree in front of the house, +and the March Hare and the Hatter were having tea at it: a +Dormouse was sitting between them, fast asleep, and the other two +were using it as a cushion, resting their elbows on it, and the +talking over its head. `Very uncomfortable for the Dormouse,' +thought Alice; `only, as it's asleep, I suppose it doesn't mind.' + + The table was a large one, but the three were all crowded +together at one corner of it: `No room! No room!' they cried +out when they saw Alice coming. `There's PLENTY of room!' said +Alice indignantly, and she sat down in a large arm-chair at one +end of the table. + + `Have some wine,' the March Hare said in an encouraging tone. + + Alice looked all round the table, but there was nothing on it +but tea. `I don't see any wine,' she remarked. + + `There isn't any,' said the March Hare. + + `Then it wasn't very civil of you to offer it,' said Alice +angrily. + + `It wasn't very civil of you to sit down without being +invited,' said the March Hare. + + `I didn't know it was YOUR table,' said Alice; `it's laid for a +great many more than three.' + + `Your hair wants cutting,' said the Hatter. He had been +looking at Alice for some time with great curiosity, and this was +his first speech. + + `You should learn not to make personal remarks,' Alice said +with some severity; `it's very rude.' + + The Hatter opened his eyes very wide on hearing this; but all +he SAID was, `Why is a raven like a writing-desk?' + + `Come, we shall have some fun now!' thought Alice. `I'm glad +they've begun asking riddles.--I believe I can guess that,' she +added aloud. + + `Do you mean that you think you can find out the answer to it?' +said the March Hare. + + `Exactly so,' said Alice. + + `Then you should say what you mean,' the March Hare went on. + + `I do,' Alice hastily replied; `at least--at least I mean what +I say--that's the same thing, you know.' + + `Not the same thing a bit!' said the Hatter. `You might just +as well say that "I see what I eat" is the same thing as "I eat +what I see"!' + + `You might just as well say,' added the March Hare, `that "I +like what I get" is the same thing as "I get what I like"!' + + `You might just as well say,' added the Dormouse, who seemed to +be talking in his sleep, `that "I breathe when I sleep" is the +same thing as "I sleep when I breathe"!' + + `It IS the same thing with you,' said the Hatter, and here the +conversation dropped, and the party sat silent for a minute, +while Alice thought over all she could remember about ravens and +writing-desks, which wasn't much. + + The Hatter was the first to break the silence. `What day of +the month is it?' he said, turning to Alice: he had taken his +watch out of his pocket, and was looking at it uneasily, shaking +it every now and then, and holding it to his ear. + + Alice considered a little, and then said `The fourth.' + + `Two days wrong!' sighed the Hatter. `I told you butter +wouldn't suit the works!' he added looking angrily at the March +Hare. + + `It was the BEST butter,' the March Hare meekly replied. + + `Yes, but some crumbs must have got in as well,' the Hatter +grumbled: `you shouldn't have put it in with the bread-knife.' + + The March Hare took the watch and looked at it gloomily: then +he dipped it into his cup of tea, and looked at it again: but he +could think of nothing better to say than his first remark, `It +was the BEST butter, you know.' + + Alice had been looking over his shoulder with some curiosity. +`What a funny watch!' she remarked. `It tells the day of the +month, and doesn't tell what o'clock it is!' + + `Why should it?' muttered the Hatter. `Does YOUR watch tell +you what year it is?' + + `Of course not,' Alice replied very readily: `but that's +because it stays the same year for such a long time together.' + + `Which is just the case with MINE,' said the Hatter. + + Alice felt dreadfully puzzled. The Hatter's remark seemed to +have no sort of meaning in it, and yet it was certainly English. +`I don't quite understand you,' she said, as politely as she +could. + + `The Dormouse is asleep again,' said the Hatter, and he poured +a little hot tea upon its nose. + + The Dormouse shook its head impatiently, and said, without +opening its eyes, `Of course, of course; just what I was going to +remark myself.' + + `Have you guessed the riddle yet?' the Hatter said, turning to +Alice again. + + `No, I give it up,' Alice replied: `what's the answer?' + + `I haven't the slightest idea,' said the Hatter. + + `Nor I,' said the March Hare. + + Alice sighed wearily. `I think you might do something better +with the time,' she said, `than waste it in asking riddles that +have no answers.' + + `If you knew Time as well as I do,' said the Hatter, `you +wouldn't talk about wasting IT. It's HIM.' + + `I don't know what you mean,' said Alice. + + `Of course you don't!' the Hatter said, tossing his head +contemptuously. `I dare say you never even spoke to Time!' + + `Perhaps not,' Alice cautiously replied: `but I know I have to +beat time when I learn music.' + + `Ah! that accounts for it,' said the Hatter. `He won't stand +beating. Now, if you only kept on good terms with him, he'd do +almost anything you liked with the clock. For instance, suppose +it were nine o'clock in the morning, just time to begin lessons: +you'd only have to whisper a hint to Time, and round goes the +clock in a twinkling! Half-past one, time for dinner!' + + (`I only wish it was,' the March Hare said to itself in a +whisper.) + + `That would be grand, certainly,' said Alice thoughtfully: +`but then--I shouldn't be hungry for it, you know.' + + `Not at first, perhaps,' said the Hatter: `but you could keep +it to half-past one as long as you liked.' + + `Is that the way YOU manage?' Alice asked. + + The Hatter shook his head mournfully. `Not I!' he replied. +`We quarrelled last March--just before HE went mad, you know--' +(pointing with his tea spoon at the March Hare,) `--it was at the +great concert given by the Queen of Hearts, and I had to sing + + "Twinkle, twinkle, little bat! + How I wonder what you're at!" + +You know the song, perhaps?' + + `I've heard something like it,' said Alice. + + `It goes on, you know,' the Hatter continued, `in this way:-- + + "Up above the world you fly, + Like a tea-tray in the sky. + Twinkle, twinkle--"' + +Here the Dormouse shook itself, and began singing in its sleep +`Twinkle, twinkle, twinkle, twinkle--' and went on so long that +they had to pinch it to make it stop. + + `Well, I'd hardly finished the first verse,' said the Hatter, +`when the Queen jumped up and bawled out, "He's murdering the +time! Off with his head!"' + + `How dreadfully savage!' exclaimed Alice. + + `And ever since that,' the Hatter went on in a mournful tone, +`he won't do a thing I ask! It's always six o'clock now.' + + A bright idea came into Alice's head. `Is that the reason so +many tea-things are put out here?' she asked. + + `Yes, that's it,' said the Hatter with a sigh: `it's always +tea-time, and we've no time to wash the things between whiles.' + + `Then you keep moving round, I suppose?' said Alice. + + `Exactly so,' said the Hatter: `as the things get used up.' + + `But what happens when you come to the beginning again?' Alice +ventured to ask. + + `Suppose we change the subject,' the March Hare interrupted, +yawning. `I'm getting tired of this. I vote the young lady +tells us a story.' + + `I'm afraid I don't know one,' said Alice, rather alarmed at +the proposal. + + `Then the Dormouse shall!' they both cried. `Wake up, +Dormouse!' And they pinched it on both sides at once. + + The Dormouse slowly opened his eyes. `I wasn't asleep,' he +said in a hoarse, feeble voice: `I heard every word you fellows +were saying.' + + `Tell us a story!' said the March Hare. + + `Yes, please do!' pleaded Alice. + + `And be quick about it,' added the Hatter, `or you'll be asleep +again before it's done.' + + `Once upon a time there were three little sisters,' the +Dormouse began in a great hurry; `and their names were Elsie, +Lacie, and Tillie; and they lived at the bottom of a well--' + + `What did they live on?' said Alice, who always took a great +interest in questions of eating and drinking. + + `They lived on treacle,' said the Dormouse, after thinking a +minute or two. + + `They couldn't have done that, you know,' Alice gently +remarked; `they'd have been ill.' + + `So they were,' said the Dormouse; `VERY ill.' + + Alice tried to fancy to herself what such an extraordinary ways +of living would be like, but it puzzled her too much, so she went +on: `But why did they live at the bottom of a well?' + + `Take some more tea,' the March Hare said to Alice, very +earnestly. + + `I've had nothing yet,' Alice replied in an offended tone, `so +I can't take more.' + + `You mean you can't take LESS,' said the Hatter: `it's very +easy to take MORE than nothing.' + + `Nobody asked YOUR opinion,' said Alice. + + `Who's making personal remarks now?' the Hatter asked +triumphantly. + + Alice did not quite know what to say to this: so she helped +herself to some tea and bread-and-butter, and then turned to the +Dormouse, and repeated her question. `Why did they live at the +bottom of a well?' + + The Dormouse again took a minute or two to think about it, and +then said, `It was a treacle-well.' + + `There's no such thing!' Alice was beginning very angrily, but +the Hatter and the March Hare went `Sh! sh!' and the Dormouse +sulkily remarked, `If you can't be civil, you'd better finish the +story for yourself.' + + `No, please go on!' Alice said very humbly; `I won't interrupt +again. I dare say there may be ONE.' + + `One, indeed!' said the Dormouse indignantly. However, he +consented to go on. `And so these three little sisters--they +were learning to draw, you know--' + + `What did they draw?' said Alice, quite forgetting her promise. + + `Treacle,' said the Dormouse, without considering at all this +time. + + `I want a clean cup,' interrupted the Hatter: `let's all move +one place on.' + + He moved on as he spoke, and the Dormouse followed him: the +March Hare moved into the Dormouse's place, and Alice rather +unwillingly took the place of the March Hare. The Hatter was the +only one who got any advantage from the change: and Alice was a +good deal worse off than before, as the March Hare had just upset +the milk-jug into his plate. + + Alice did not wish to offend the Dormouse again, so she began +very cautiously: `But I don't understand. Where did they draw +the treacle from?' + + `You can draw water out of a water-well,' said the Hatter; `so +I should think you could draw treacle out of a treacle-well--eh, +stupid?' + + `But they were IN the well,' Alice said to the Dormouse, not +choosing to notice this last remark. + + `Of course they were', said the Dormouse; `--well in.' + + This answer so confused poor Alice, that she let the Dormouse +go on for some time without interrupting it. + + `They were learning to draw,' the Dormouse went on, yawning and +rubbing its eyes, for it was getting very sleepy; `and they drew +all manner of things--everything that begins with an M--' + + `Why with an M?' said Alice. + + `Why not?' said the March Hare. + + Alice was silent. + + The Dormouse had closed its eyes by this time, and was going +off into a doze; but, on being pinched by the Hatter, it woke up +again with a little shriek, and went on: `--that begins with an +M, such as mouse-traps, and the moon, and memory, and muchness-- +you know you say things are "much of a muchness"--did you ever +see such a thing as a drawing of a muchness?' + + `Really, now you ask me,' said Alice, very much confused, `I +don't think--' + + `Then you shouldn't talk,' said the Hatter. + + This piece of rudeness was more than Alice could bear: she got +up in great disgust, and walked off; the Dormouse fell asleep +instantly, and neither of the others took the least notice of her +going, though she looked back once or twice, half hoping that +they would call after her: the last time she saw them, they were +trying to put the Dormouse into the teapot. + + `At any rate I'll never go THERE again!' said Alice as she +picked her way through the wood. `It's the stupidest tea-party I +ever was at in all my life!' + + Just as she said this, she noticed that one of the trees had a +door leading right into it. `That's very curious!' she thought. +`But everything's curious today. I think I may as well go in at +once.' And in she went. + + Once more she found herself in the long hall, and close to the +little glass table. `Now, I'll manage better this time,' she +said to herself, and began by taking the little golden key, and +unlocking the door that led into the garden. Then she went to +work nibbling at the mushroom (she had kept a piece of it in her +pocked) till she was about a foot high: then she walked down the +little passage: and THEN--she found herself at last in the +beautiful garden, among the bright flower-beds and the cool +fountains. + + + + CHAPTER VIII + + The Queen's Croquet-Ground + + + A large rose-tree stood near the entrance of the garden: the +roses growing on it were white, but there were three gardeners at +it, busily painting them red. Alice thought this a very curious +thing, and she went nearer to watch them, and just as she came up +to them she heard one of them say, `Look out now, Five! Don't go +splashing paint over me like that!' + + `I couldn't help it,' said Five, in a sulky tone; `Seven jogged +my elbow.' + + On which Seven looked up and said, `That's right, Five! Always +lay the blame on others!' + + `YOU'D better not talk!' said Five. `I heard the Queen say only +yesterday you deserved to be beheaded!' + + `What for?' said the one who had spoken first. + + `That's none of YOUR business, Two!' said Seven. + + `Yes, it IS his business!' said Five, `and I'll tell him--it +was for bringing the cook tulip-roots instead of onions.' + + Seven flung down his brush, and had just begun `Well, of all +the unjust things--' when his eye chanced to fall upon Alice, as +she stood watching them, and he checked himself suddenly: the +others looked round also, and all of them bowed low. + + `Would you tell me,' said Alice, a little timidly, `why you are +painting those roses?' + + Five and Seven said nothing, but looked at Two. Two began in a +low voice, `Why the fact is, you see, Miss, this here ought to +have been a RED rose-tree, and we put a white one in by mistake; +and if the Queen was to find it out, we should all have our heads +cut off, you know. So you see, Miss, we're doing our best, afore +she comes, to--' At this moment Five, who had been anxiously +looking across the garden, called out `The Queen! The Queen!' +and the three gardeners instantly threw themselves flat upon +their faces. There was a sound of many footsteps, and Alice +looked round, eager to see the Queen. + + First came ten soldiers carrying clubs; these were all shaped +like the three gardeners, oblong and flat, with their hands and +feet at the corners: next the ten courtiers; these were +ornamented all over with diamonds, and walked two and two, as the +soldiers did. After these came the royal children; there were +ten of them, and the little dears came jumping merrily along hand +in hand, in couples: they were all ornamented with hearts. Next +came the guests, mostly Kings and Queens, and among them Alice +recognised the White Rabbit: it was talking in a hurried nervous +manner, smiling at everything that was said, and went by without +noticing her. Then followed the Knave of Hearts, carrying the +King's crown on a crimson velvet cushion; and, last of all this +grand procession, came THE KING AND QUEEN OF HEARTS. + + Alice was rather doubtful whether she ought not to lie down on +her face like the three gardeners, but she could not remember +every having heard of such a rule at processions; `and besides, +what would be the use of a procession,' thought she, `if people +had all to lie down upon their faces, so that they couldn't see +it?' So she stood still where she was, and waited. + + When the procession came opposite to Alice, they all stopped +and looked at her, and the Queen said severely `Who is this?' +She said it to the Knave of Hearts, who only bowed and smiled in +reply. + + `Idiot!' said the Queen, tossing her head impatiently; and, +turning to Alice, she went on, `What's your name, child?' + + `My name is Alice, so please your Majesty,' said Alice very +politely; but she added, to herself, `Why, they're only a pack of +cards, after all. I needn't be afraid of them!' + + `And who are THESE?' said the Queen, pointing to the three +gardeners who were lying round the rosetree; for, you see, as +they were lying on their faces, and the pattern on their backs +was the same as the rest of the pack, she could not tell whether +they were gardeners, or soldiers, or courtiers, or three of her +own children. + + `How should I know?' said Alice, surprised at her own courage. +`It's no business of MINE.' + + The Queen turned crimson with fury, and, after glaring at her +for a moment like a wild beast, screamed `Off with her head! +Off--' + + `Nonsense!' said Alice, very loudly and decidedly, and the +Queen was silent. + + The King laid his hand upon her arm, and timidly said +`Consider, my dear: she is only a child!' + + The Queen turned angrily away from him, and said to the Knave +`Turn them over!' + + The Knave did so, very carefully, with one foot. + + `Get up!' said the Queen, in a shrill, loud voice, and the +three gardeners instantly jumped up, and began bowing to the +King, the Queen, the royal children, and everybody else. + + `Leave off that!' screamed the Queen. `You make me giddy.' +And then, turning to the rose-tree, she went on, `What HAVE you +been doing here?' + + `May it please your Majesty,' said Two, in a very humble tone, +going down on one knee as he spoke, `we were trying--' + + `I see!' said the Queen, who had meanwhile been examining the +roses. `Off with their heads!' and the procession moved on, +three of the soldiers remaining behind to execute the unfortunate +gardeners, who ran to Alice for protection. + + `You shan't be beheaded!' said Alice, and she put them into a +large flower-pot that stood near. The three soldiers wandered +about for a minute or two, looking for them, and then quietly +marched off after the others. + + `Are their heads off?' shouted the Queen. + + `Their heads are gone, if it please your Majesty!' the soldiers +shouted in reply. + + `That's right!' shouted the Queen. `Can you play croquet?' + + The soldiers were silent, and looked at Alice, as the question +was evidently meant for her. + + `Yes!' shouted Alice. + + `Come on, then!' roared the Queen, and Alice joined the +procession, wondering very much what would happen next. + + `It's--it's a very fine day!' said a timid voice at her side. +She was walking by the White Rabbit, who was peeping anxiously +into her face. + + `Very,' said Alice: `--where's the Duchess?' + + `Hush! Hush!' said the Rabbit in a low, hurried tone. He +looked anxiously over his shoulder as he spoke, and then raised +himself upon tiptoe, put his mouth close to her ear, and +whispered `She's under sentence of execution.' + + `What for?' said Alice. + + `Did you say "What a pity!"?' the Rabbit asked. + + `No, I didn't,' said Alice: `I don't think it's at all a pity. +I said "What for?"' + + `She boxed the Queen's ears--' the Rabbit began. Alice gave a +little scream of laughter. `Oh, hush!' the Rabbit whispered in a +frightened tone. `The Queen will hear you! You see, she came +rather late, and the Queen said--' + + `Get to your places!' shouted the Queen in a voice of thunder, +and people began running about in all directions, tumbling up +against each other; however, they got settled down in a minute or +two, and the game began. Alice thought she had never seen such a +curious croquet-ground in her life; it was all ridges and +furrows; the balls were live hedgehogs, the mallets live +flamingoes, and the soldiers had to double themselves up and to +stand on their hands and feet, to make the arches. + + The chief difficulty Alice found at first was in managing her +flamingo: she succeeded in getting its body tucked away, +comfortably enough, under her arm, with its legs hanging down, +but generally, just as she had got its neck nicely straightened +out, and was going to give the hedgehog a blow with its head, it +WOULD twist itself round and look up in her face, with such a +puzzled expression that she could not help bursting out laughing: +and when she had got its head down, and was going to begin again, +it was very provoking to find that the hedgehog had unrolled +itself, and was in the act of crawling away: besides all this, +there was generally a ridge or furrow in the way wherever she +wanted to send the hedgehog to, and, as the doubled-up soldiers +were always getting up and walking off to other parts of the +ground, Alice soon came to the conclusion that it was a very +difficult game indeed. + + The players all played at once without waiting for turns, +quarrelling all the while, and fighting for the hedgehogs; and in +a very short time the Queen was in a furious passion, and went +stamping about, and shouting `Off with his head!' or `Off with +her head!' about once in a minute. + + Alice began to feel very uneasy: to be sure, she had not as +yet had any dispute with the Queen, but she knew that it might +happen any minute, `and then,' thought she, `what would become of +me? They're dreadfully fond of beheading people here; the great +wonder is, that there's any one left alive!' + + She was looking about for some way of escape, and wondering +whether she could get away without being seen, when she noticed a +curious appearance in the air: it puzzled her very much at +first, but, after watching it a minute or two, she made it out to +be a grin, and she said to herself `It's the Cheshire Cat: now I +shall have somebody to talk to.' + + `How are you getting on?' said the Cat, as soon as there was +mouth enough for it to speak with. + + Alice waited till the eyes appeared, and then nodded. `It's no +use speaking to it,' she thought, `till its ears have come, or at +least one of them.' In another minute the whole head appeared, +and then Alice put down her flamingo, and began an account of the +game, feeling very glad she had someone to listen to her. The +Cat seemed to think that there was enough of it now in sight, and +no more of it appeared. + + `I don't think they play at all fairly,' Alice began, in rather +a complaining tone, `and they all quarrel so dreadfully one can't +hear oneself speak--and they don't seem to have any rules in +particular; at least, if there are, nobody attends to them--and +you've no idea how confusing it is all the things being alive; +for instance, there's the arch I've got to go through next +walking about at the other end of the ground--and I should have +croqueted the Queen's hedgehog just now, only it ran away when it +saw mine coming!' + + `How do you like the Queen?' said the Cat in a low voice. + + `Not at all,' said Alice: `she's so extremely--' Just then +she noticed that the Queen was close behind her, listening: so +she went on, `--likely to win, that it's hardly worth while +finishing the game.' + + The Queen smiled and passed on. + + `Who ARE you talking to?' said the King, going up to Alice, and +looking at the Cat's head with great curiosity. + + `It's a friend of mine--a Cheshire Cat,' said Alice: `allow me +to introduce it.' + + `I don't like the look of it at all,' said the King: `however, +it may kiss my hand if it likes.' + + `I'd rather not,' the Cat remarked. + + `Don't be impertinent,' said the King, `and don't look at me +like that!' He got behind Alice as he spoke. + + `A cat may look at a king,' said Alice. `I've read that in +some book, but I don't remember where.' + + `Well, it must be removed,' said the King very decidedly, and +he called the Queen, who was passing at the moment, `My dear! I +wish you would have this cat removed!' + + The Queen had only one way of settling all difficulties, great +or small. `Off with his head!' she said, without even looking +round. + + `I'll fetch the executioner myself,' said the King eagerly, and +he hurried off. + + Alice thought she might as well go back, and see how the game +was going on, as she heard the Queen's voice in the distance, +screaming with passion. She had already heard her sentence three +of the players to be executed for having missed their turns, and +she did not like the look of things at all, as the game was in +such confusion that she never knew whether it was her turn or +not. So she went in search of her hedgehog. + + The hedgehog was engaged in a fight with another hedgehog, +which seemed to Alice an excellent opportunity for croqueting one +of them with the other: the only difficulty was, that her +flamingo was gone across to the other side of the garden, where +Alice could see it trying in a helpless sort of way to fly up +into a tree. + + By the time she had caught the flamingo and brought it back, +the fight was over, and both the hedgehogs were out of sight: +`but it doesn't matter much,' thought Alice, `as all the arches +are gone from this side of the ground.' So she tucked it away +under her arm, that it might not escape again, and went back for +a little more conversation with her friend. + + When she got back to the Cheshire Cat, she was surprised to +find quite a large crowd collected round it: there was a dispute +going on between the executioner, the King, and the Queen, who +were all talking at once, while all the rest were quite silent, +and looked very uncomfortable. + + The moment Alice appeared, she was appealed to by all three to +settle the question, and they repeated their arguments to her, +though, as they all spoke at once, she found it very hard indeed +to make out exactly what they said. + + The executioner's argument was, that you couldn't cut off a +head unless there was a body to cut it off from: that he had +never had to do such a thing before, and he wasn't going to begin +at HIS time of life. + + The King's argument was, that anything that had a head could be +beheaded, and that you weren't to talk nonsense. + + The Queen's argument was, that if something wasn't done about +it in less than no time she'd have everybody executed, all round. +(It was this last remark that had made the whole party look so +grave and anxious.) + + Alice could think of nothing else to say but `It belongs to the +Duchess: you'd better ask HER about it.' + + `She's in prison,' the Queen said to the executioner: `fetch +her here.' And the executioner went off like an arrow. + + The Cat's head began fading away the moment he was gone, and, +by the time he had come back with the Dutchess, it had entirely +disappeared; so the King and the executioner ran wildly up and +down looking for it, while the rest of the party went back to the game. + + + + CHAPTER IX + + The Mock Turtle's Story + + + `You can't think how glad I am to see you again, you dear old +thing!' said the Duchess, as she tucked her arm affectionately +into Alice's, and they walked off together. + + Alice was very glad to find her in such a pleasant temper, and +thought to herself that perhaps it was only the pepper that had +made her so savage when they met in the kitchen. + + `When I'M a Duchess,' she said to herself, (not in a very +hopeful tone though), `I won't have any pepper in my kitchen AT +ALL. Soup does very well without--Maybe it's always pepper that +makes people hot-tempered,' she went on, very much pleased at +having found out a new kind of rule, `and vinegar that makes them +sour--and camomile that makes them bitter--and--and barley-sugar +and such things that make children sweet-tempered. I only wish +people knew that: then they wouldn't be so stingy about it, you +know--' + + She had quite forgotten the Duchess by this time, and was a +little startled when she heard her voice close to her ear. +`You're thinking about something, my dear, and that makes you +forget to talk. I can't tell you just now what the moral of that +is, but I shall remember it in a bit.' + + `Perhaps it hasn't one,' Alice ventured to remark. + + `Tut, tut, child!' said the Duchess. `Everything's got a +moral, if only you can find it.' And she squeezed herself up +closer to Alice's side as she spoke. + + Alice did not much like keeping so close to her: first, +because the Duchess was VERY ugly; and secondly, because she was +exactly the right height to rest her chin upon Alice's shoulder, +and it was an uncomfortably sharp chin. However, she did not +like to be rude, so she bore it as well as she could. + + `The game's going on rather better now,' she said, by way of +keeping up the conversation a little. + + `'Tis so,' said the Duchess: `and the moral of that is--"Oh, +'tis love, 'tis love, that makes the world go round!"' + + `Somebody said,' Alice whispered, `that it's done by everybody +minding their own business!' + + `Ah, well! It means much the same thing,' said the Duchess, +digging her sharp little chin into Alice's shoulder as she added, +`and the moral of THAT is--"Take care of the sense, and the +sounds will take care of themselves."' + + `How fond she is of finding morals in things!' Alice thought to +herself. + + `I dare say you're wondering why I don't put my arm round your +waist,' the Duchess said after a pause: `the reason is, that I'm +doubtful about the temper of your flamingo. Shall I try the +experiment?' + + `HE might bite,' Alice cautiously replied, not feeling at all +anxious to have the experiment tried. + + `Very true,' said the Duchess: `flamingoes and mustard both +bite. And the moral of that is--"Birds of a feather flock +together."' + + `Only mustard isn't a bird,' Alice remarked. + + `Right, as usual,' said the Duchess: `what a clear way you +have of putting things!' + + `It's a mineral, I THINK,' said Alice. + + `Of course it is,' said the Duchess, who seemed ready to agree +to everything that Alice said; `there's a large mustard-mine near +here. And the moral of that is--"The more there is of mine, the +less there is of yours."' + + `Oh, I know!' exclaimed Alice, who had not attended to this +last remark, `it's a vegetable. It doesn't look like one, but it +is.' + + `I quite agree with you,' said the Duchess; `and the moral of +that is--"Be what you would seem to be"--or if you'd like it put +more simply--"Never imagine yourself not to be otherwise than +what it might appear to others that what you were or might have +been was not otherwise than what you had been would have appeared +to them to be otherwise."' + + `I think I should understand that better,' Alice said very +politely, `if I had it written down: but I can't quite follow it +as you say it.' + + `That's nothing to what I could say if I chose,' the Duchess +replied, in a pleased tone. + + `Pray don't trouble yourself to say it any longer than that,' +said Alice. + + `Oh, don't talk about trouble!' said the Duchess. `I make you +a present of everything I've said as yet.' + + `A cheap sort of present!' thought Alice. `I'm glad they don't +give birthday presents like that!' But she did not venture to +say it out loud. + + `Thinking again?' the Duchess asked, with another dig of her +sharp little chin. + + `I've a right to think,' said Alice sharply, for she was +beginning to feel a little worried. + + `Just about as much right,' said the Duchess, `as pigs have to +fly; and the m--' + + But here, to Alice's great surprise, the Duchess's voice died +away, even in the middle of her favourite word `moral,' and the +arm that was linked into hers began to tremble. Alice looked up, +and there stood the Queen in front of them, with her arms folded, +frowning like a thunderstorm. + + `A fine day, your Majesty!' the Duchess began in a low, weak +voice. + + `Now, I give you fair warning,' shouted the Queen, stamping on +the ground as she spoke; `either you or your head must be off, +and that in about half no time! Take your choice!' + + The Duchess took her choice, and was gone in a moment. + + `Let's go on with the game,' the Queen said to Alice; and Alice +was too much frightened to say a word, but slowly followed her +back to the croquet-ground. + + The other guests had taken advantage of the Queen's absence, +and were resting in the shade: however, the moment they saw her, +they hurried back to the game, the Queen merely remarking that a +moment's delay would cost them their lives. + + All the time they were playing the Queen never left off +quarrelling with the other players, and shouting `Off with his +head!' or `Off with her head!' Those whom she sentenced were +taken into custody by the soldiers, who of course had to leave +off being arches to do this, so that by the end of half an hour +or so there were no arches left, and all the players, except the +King, the Queen, and Alice, were in custody and under sentence of +execution. + + Then the Queen left off, quite out of breath, and said to +Alice, `Have you seen the Mock Turtle yet?' + + `No,' said Alice. `I don't even know what a Mock Turtle is.' + + `It's the thing Mock Turtle Soup is made from,' said the Queen. + + `I never saw one, or heard of one,' said Alice. + + `Come on, then,' said the Queen, `and he shall tell you his +history,' + + As they walked off together, Alice heard the King say in a low +voice, to the company generally, `You are all pardoned.' `Come, +THAT'S a good thing!' she said to herself, for she had felt quite +unhappy at the number of executions the Queen had ordered. + + They very soon came upon a Gryphon, lying fast asleep in the +sun. (IF you don't know what a Gryphon is, look at the picture.) +`Up, lazy thing!' said the Queen, `and take this young lady to +see the Mock Turtle, and to hear his history. I must go back and +see after some executions I have ordered'; and she walked off, +leaving Alice alone with the Gryphon. Alice did not quite like +the look of the creature, but on the whole she thought it would +be quite as safe to stay with it as to go after that savage +Queen: so she waited. + + The Gryphon sat up and rubbed its eyes: then it watched the +Queen till she was out of sight: then it chuckled. `What fun!' +said the Gryphon, half to itself, half to Alice. + + `What IS the fun?' said Alice. + + `Why, SHE,' said the Gryphon. `It's all her fancy, that: they +never executes nobody, you know. Come on!' + + `Everybody says "come on!" here,' thought Alice, as she went +slowly after it: `I never was so ordered about in all my life, +never!' + + They had not gone far before they saw the Mock Turtle in the +distance, sitting sad and lonely on a little ledge of rock, and, +as they came nearer, Alice could hear him sighing as if his heart +would break. She pitied him deeply. `What is his sorrow?' she +asked the Gryphon, and the Gryphon answered, very nearly in the +same words as before, `It's all his fancy, that: he hasn't got +no sorrow, you know. Come on!' + + So they went up to the Mock Turtle, who looked at them with +large eyes full of tears, but said nothing. + + `This here young lady,' said the Gryphon, `she wants for to +know your history, she do.' + + `I'll tell it her,' said the Mock Turtle in a deep, hollow +tone: `sit down, both of you, and don't speak a word till I've +finished.' + + So they sat down, and nobody spoke for some minutes. Alice +thought to herself, `I don't see how he can EVEN finish, if he +doesn't begin.' But she waited patiently. + + `Once,' said the Mock Turtle at last, with a deep sigh, `I was +a real Turtle.' + + These words were followed by a very long silence, broken only +by an occasional exclamation of `Hjckrrh!' from the Gryphon, and +the constant heavy sobbing of the Mock Turtle. Alice was very +nearly getting up and saying, `Thank you, sir, for your +interesting story,' but she could not help thinking there MUST be +more to come, so she sat still and said nothing. + + `When we were little,' the Mock Turtle went on at last, more +calmly, though still sobbing a little now and then, `we went to +school in the sea. The master was an old Turtle--we used to call +him Tortoise--' + + `Why did you call him Tortoise, if he wasn't one?' Alice asked. + + `We called him Tortoise because he taught us,' said the Mock +Turtle angrily: `really you are very dull!' + + `You ought to be ashamed of yourself for asking such a simple +question,' added the Gryphon; and then they both sat silent and +looked at poor Alice, who felt ready to sink into the earth. At +last the Gryphon said to the Mock Turtle, `Drive on, old fellow! +Don't be all day about it!' and he went on in these words: + + `Yes, we went to school in the sea, though you mayn't believe +it--' + + `I never said I didn't!' interrupted Alice. + + `You did,' said the Mock Turtle. + + `Hold your tongue!' added the Gryphon, before Alice could speak +again. The Mock Turtle went on. + + `We had the best of educations--in fact, we went to school +every day--' + + `I'VE been to a day-school, too,' said Alice; `you needn't be +so proud as all that.' + + `With extras?' asked the Mock Turtle a little anxiously. + + `Yes,' said Alice, `we learned French and music.' + + `And washing?' said the Mock Turtle. + + `Certainly not!' said Alice indignantly. + + `Ah! then yours wasn't a really good school,' said the Mock +Turtle in a tone of great relief. `Now at OURS they had at the +end of the bill, "French, music, AND WASHING--extra."' + + `You couldn't have wanted it much,' said Alice; `living at the +bottom of the sea.' + + `I couldn't afford to learn it.' said the Mock Turtle with a +sigh. `I only took the regular course.' + + `What was that?' inquired Alice. + + `Reeling and Writhing, of course, to begin with,' the Mock +Turtle replied; `and then the different branches of Arithmetic-- +Ambition, Distraction, Uglification, and Derision.' + + `I never heard of "Uglification,"' Alice ventured to say. `What +is it?' + + The Gryphon lifted up both its paws in surprise. `What! Never +heard of uglifying!' it exclaimed. `You know what to beautify +is, I suppose?' + + `Yes,' said Alice doubtfully: `it means--to--make--anything-- +prettier.' + + `Well, then,' the Gryphon went on, `if you don't know what to +uglify is, you ARE a simpleton.' + + Alice did not feel encouraged to ask any more questions about +it, so she turned to the Mock Turtle, and said `What else had you +to learn?' + + `Well, there was Mystery,' the Mock Turtle replied, counting +off the subjects on his flappers, `--Mystery, ancient and modern, +with Seaography: then Drawling--the Drawling-master was an old +conger-eel, that used to come once a week: HE taught us +Drawling, Stretching, and Fainting in Coils.' + + `What was THAT like?' said Alice. + + `Well, I can't show it you myself,' the Mock Turtle said: `I'm +too stiff. And the Gryphon never learnt it.' + + `Hadn't time,' said the Gryphon: `I went to the Classics +master, though. He was an old crab, HE was.' + + `I never went to him,' the Mock Turtle said with a sigh: `he +taught Laughing and Grief, they used to say.' + + `So he did, so he did,' said the Gryphon, sighing in his turn; +and both creatures hid their faces in their paws. + + `And how many hours a day did you do lessons?' said Alice, in a +hurry to change the subject. + + `Ten hours the first day,' said the Mock Turtle: `nine the +next, and so on.' + + `What a curious plan!' exclaimed Alice. + + `That's the reason they're called lessons,' the Gryphon +remarked: `because they lessen from day to day.' + + This was quite a new idea to Alice, and she thought it over a +little before she made her next remark. `Then the eleventh day +must have been a holiday?' + + `Of course it was,' said the Mock Turtle. + + `And how did you manage on the twelfth?' Alice went on eagerly. + + `That's enough about lessons,' the Gryphon interrupted in a +very decided tone: `tell her something about the games now.' + + + + CHAPTER X + + The Lobster Quadrille + + + The Mock Turtle sighed deeply, and drew the back of one flapper +across his eyes. He looked at Alice, and tried to speak, but for +a minute or two sobs choked his voice. `Same as if he had a bone +in his throat,' said the Gryphon: and it set to work shaking him +and punching him in the back. At last the Mock Turtle recovered +his voice, and, with tears running down his cheeks, he went on +again:-- + + `You may not have lived much under the sea--' (`I haven't,' +said Alice)--`and perhaps you were never even introduced to a lobster--' +(Alice began to say `I once tasted--' but checked herself hastily, +and said `No, never') `--so you can have no idea what a delightful +thing a Lobster Quadrille is!' + + `No, indeed,' said Alice. `What sort of a dance is it?' + + `Why,' said the Gryphon, `you first form into a line along the +sea-shore--' + + `Two lines!' cried the Mock Turtle. `Seals, turtles, salmon, +and so on; then, when you've cleared all the jelly-fish out of +the way--' + + `THAT generally takes some time,' interrupted the Gryphon. + + `--you advance twice--' + + `Each with a lobster as a partner!' cried the Gryphon. + + `Of course,' the Mock Turtle said: `advance twice, set to +partners--' + + `--change lobsters, and retire in same order,' continued the +Gryphon. + + `Then, you know,' the Mock Turtle went on, `you throw the--' + + `The lobsters!' shouted the Gryphon, with a bound into the air. + + `--as far out to sea as you can--' + + `Swim after them!' screamed the Gryphon. + + `Turn a somersault in the sea!' cried the Mock Turtle, +capering wildly about. + + `Back to land again, and that's all the first figure,' said the +Mock Turtle, suddenly dropping his voice; and the two creatures, +who had been jumping about like mad things all this time, sat +down again very sadly and quietly, and looked at Alice. + + `It must be a very pretty dance,' said Alice timidly. + + `Would you like to see a little of it?' said the Mock Turtle. + + `Very much indeed,' said Alice. + + `Come, let's try the first figure!' said the Mock Turtle to the +Gryphon. `We can do without lobsters, you know. Which shall +sing?' + + `Oh, YOU sing,' said the Gryphon. `I've forgotten the words.' + + So they began solemnly dancing round and round Alice, every now +and then treading on her toes when they passed too close, and +waving their forepaws to mark the time, while the Mock Turtle +sang this, very slowly and sadly:-- + + +`"Will you walk a little faster?" said a whiting to a snail. +"There's a porpoise close behind us, and he's treading on my + tail. +See how eagerly the lobsters and the turtles all advance! +They are waiting on the shingle--will you come and join the +dance? + +Will you, won't you, will you, won't you, will you join the +dance? +Will you, won't you, will you, won't you, won't you join the +dance? + + +"You can really have no notion how delightful it will be +When they take us up and throw us, with the lobsters, out to + sea!" +But the snail replied "Too far, too far!" and gave a look + askance-- +Said he thanked the whiting kindly, but he would not join the + dance. + Would not, could not, would not, could not, would not join + the dance. + Would not, could not, would not, could not, could not join + the dance. + +`"What matters it how far we go?" his scaly friend replied. +"There is another shore, you know, upon the other side. +The further off from England the nearer is to France-- +Then turn not pale, beloved snail, but come and join the dance. + + Will you, won't you, will you, won't you, will you join the + dance? + Will you, won't you, will you, won't you, won't you join the + dance?"' + + + + `Thank you, it's a very interesting dance to watch,' said +Alice, feeling very glad that it was over at last: `and I do so +like that curious song about the whiting!' + + `Oh, as to the whiting,' said the Mock Turtle, `they--you've +seen them, of course?' + + `Yes,' said Alice, `I've often seen them at dinn--' she +checked herself hastily. + + `I don't know where Dinn may be,' said the Mock Turtle, `but +if you've seen them so often, of course you know what they're +like.' + + `I believe so,' Alice replied thoughtfully. `They have their +tails in their mouths--and they're all over crumbs.' + + `You're wrong about the crumbs,' said the Mock Turtle: +`crumbs would all wash off in the sea. But they HAVE their tails +in their mouths; and the reason is--' here the Mock Turtle +yawned and shut his eyes.--`Tell her about the reason and all +that,' he said to the Gryphon. + + `The reason is,' said the Gryphon, `that they WOULD go with +the lobsters to the dance. So they got thrown out to sea. So +they had to fall a long way. So they got their tails fast in +their mouths. So they couldn't get them out again. That's all.' + + `Thank you,' said Alice, `it's very interesting. I never knew +so much about a whiting before.' + + `I can tell you more than that, if you like,' said the +Gryphon. `Do you know why it's called a whiting?' + + `I never thought about it,' said Alice. `Why?' + + `IT DOES THE BOOTS AND SHOES.' the Gryphon replied very +solemnly. + + Alice was thoroughly puzzled. `Does the boots and shoes!' she +repeated in a wondering tone. + + `Why, what are YOUR shoes done with?' said the Gryphon. `I +mean, what makes them so shiny?' + + Alice looked down at them, and considered a little before she +gave her answer. `They're done with blacking, I believe.' + + `Boots and shoes under the sea,' the Gryphon went on in a deep +voice, `are done with a whiting. Now you know.' + + `And what are they made of?' Alice asked in a tone of great +curiosity. + + `Soles and eels, of course,' the Gryphon replied rather +impatiently: `any shrimp could have told you that.' + + `If I'd been the whiting,' said Alice, whose thoughts were +still running on the song, `I'd have said to the porpoise, "Keep +back, please: we don't want YOU with us!"' + + `They were obliged to have him with them,' the Mock Turtle +said: `no wise fish would go anywhere without a porpoise.' + + `Wouldn't it really?' said Alice in a tone of great surprise. + + `Of course not,' said the Mock Turtle: `why, if a fish came +to ME, and told me he was going a journey, I should say "With +what porpoise?"' + + `Don't you mean "purpose"?' said Alice. + + `I mean what I say,' the Mock Turtle replied in an offended +tone. And the Gryphon added `Come, let's hear some of YOUR +adventures.' + + `I could tell you my adventures--beginning from this morning,' +said Alice a little timidly: `but it's no use going back to +yesterday, because I was a different person then.' + + `Explain all that,' said the Mock Turtle. + + `No, no! The adventures first,' said the Gryphon in an +impatient tone: `explanations take such a dreadful time.' + + So Alice began telling them her adventures from the time when +she first saw the White Rabbit. She was a little nervous about +it just at first, the two creatures got so close to her, one on +each side, and opened their eyes and mouths so VERY wide, but she +gained courage as she went on. Her listeners were perfectly +quiet till she got to the part about her repeating `YOU ARE OLD, +FATHER WILLIAM,' to the Caterpillar, and the words all coming +different, and then the Mock Turtle drew a long breath, and said +`That's very curious.' + + `It's all about as curious as it can be,' said the Gryphon. + + `It all came different!' the Mock Turtle repeated +thoughtfully. `I should like to hear her try and repeat +something now. Tell her to begin.' He looked at the Gryphon as +if he thought it had some kind of authority over Alice. + + `Stand up and repeat "'TIS THE VOICE OF THE SLUGGARD,"' said +the Gryphon. + + `How the creatures order one about, and make one repeat +lessons!' thought Alice; `I might as well be at school at once.' +However, she got up, and began to repeat it, but her head was so +full of the Lobster Quadrille, that she hardly knew what she was +saying, and the words came very queer indeed:-- + + `'Tis the voice of the Lobster; I heard him declare, + "You have baked me too brown, I must sugar my hair." + As a duck with its eyelids, so he with his nose + Trims his belt and his buttons, and turns out his toes.' + + [later editions continued as follows + When the sands are all dry, he is gay as a lark, + And will talk in contemptuous tones of the Shark, + But, when the tide rises and sharks are around, + His voice has a timid and tremulous sound.] + + `That's different from what I used to say when I was a child,' +said the Gryphon. + + `Well, I never heard it before,' said the Mock Turtle; `but it +sounds uncommon nonsense.' + + Alice said nothing; she had sat down with her face in her +hands, wondering if anything would EVER happen in a natural way +again. + + `I should like to have it explained,' said the Mock Turtle. + + `She can't explain it,' said the Gryphon hastily. `Go on with +the next verse.' + + `But about his toes?' the Mock Turtle persisted. `How COULD +he turn them out with his nose, you know?' + + `It's the first position in dancing.' Alice said; but was +dreadfully puzzled by the whole thing, and longed to change the +subject. + + `Go on with the next verse,' the Gryphon repeated impatiently: +`it begins "I passed by his garden."' + + Alice did not dare to disobey, though she felt sure it would +all come wrong, and she went on in a trembling voice:-- + + `I passed by his garden, and marked, with one eye, + How the Owl and the Panther were sharing a pie--' + + [later editions continued as follows + The Panther took pie-crust, and gravy, and meat, + While the Owl had the dish as its share of the treat. + When the pie was all finished, the Owl, as a boon, + Was kindly permitted to pocket the spoon: + While the Panther received knife and fork with a growl, + And concluded the banquet--] + + `What IS the use of repeating all that stuff,' the Mock Turtle +interrupted, `if you don't explain it as you go on? It's by far +the most confusing thing I ever heard!' + + `Yes, I think you'd better leave off,' said the Gryphon: and +Alice was only too glad to do so. + + `Shall we try another figure of the Lobster Quadrille?' the +Gryphon went on. `Or would you like the Mock Turtle to sing you +a song?' + + `Oh, a song, please, if the Mock Turtle would be so kind,' +Alice replied, so eagerly that the Gryphon said, in a rather +offended tone, `Hm! No accounting for tastes! Sing her "Turtle +Soup," will you, old fellow?' + + The Mock Turtle sighed deeply, and began, in a voice sometimes +choked with sobs, to sing this:-- + + + `Beautiful Soup, so rich and green, + Waiting in a hot tureen! + Who for such dainties would not stoop? + Soup of the evening, beautiful Soup! + Soup of the evening, beautiful Soup! + Beau--ootiful Soo--oop! + Beau--ootiful Soo--oop! + Soo--oop of the e--e--evening, + Beautiful, beautiful Soup! + + `Beautiful Soup! Who cares for fish, + Game, or any other dish? + Who would not give all else for two p + ennyworth only of beautiful Soup? + Pennyworth only of beautiful Soup? + Beau--ootiful Soo--oop! + Beau--ootiful Soo--oop! + Soo--oop of the e--e--evening, + Beautiful, beauti--FUL SOUP!' + + `Chorus again!' cried the Gryphon, and the Mock Turtle had +just begun to repeat it, when a cry of `The trial's beginning!' +was heard in the distance. + + `Come on!' cried the Gryphon, and, taking Alice by the hand, +it hurried off, without waiting for the end of the song. + + `What trial is it?' Alice panted as she ran; but the Gryphon +only answered `Come on!' and ran the faster, while more and more +faintly came, carried on the breeze that followed them, the +melancholy words:-- + + `Soo--oop of the e--e--evening, + Beautiful, beautiful Soup!' + + + + CHAPTER XI + + Who Stole the Tarts? + + + The King and Queen of Hearts were seated on their throne when +they arrived, with a great crowd assembled about them--all sorts +of little birds and beasts, as well as the whole pack of cards: +the Knave was standing before them, in chains, with a soldier on +each side to guard him; and near the King was the White Rabbit, +with a trumpet in one hand, and a scroll of parchment in the +other. In the very middle of the court was a table, with a large +dish of tarts upon it: they looked so good, that it made Alice +quite hungry to look at them--`I wish they'd get the trial done,' +she thought, `and hand round the refreshments!' But there seemed +to be no chance of this, so she began looking at everything about +her, to pass away the time. + + Alice had never been in a court of justice before, but she had +read about them in books, and she was quite pleased to find that +she knew the name of nearly everything there. `That's the +judge,' she said to herself, `because of his great wig.' + + The judge, by the way, was the King; and as he wore his crown +over the wig, (look at the frontispiece if you want to see how he +did it,) he did not look at all comfortable, and it was certainly +not becoming. + + `And that's the jury-box,' thought Alice, `and those twelve +creatures,' (she was obliged to say `creatures,' you see, because +some of them were animals, and some were birds,) `I suppose they +are the jurors.' She said this last word two or three times over +to herself, being rather proud of it: for she thought, and +rightly too, that very few little girls of her age knew the +meaning of it at all. However, `jury-men' would have done just +as well. + + The twelve jurors were all writing very busily on slates. +`What are they doing?' Alice whispered to the Gryphon. `They +can't have anything to put down yet, before the trial's begun.' + + `They're putting down their names,' the Gryphon whispered in +reply, `for fear they should forget them before the end of the +trial.' + + `Stupid things!' Alice began in a loud, indignant voice, but +she stopped hastily, for the White Rabbit cried out, `Silence in +the court!' and the King put on his spectacles and looked +anxiously round, to make out who was talking. + + Alice could see, as well as if she were looking over their +shoulders, that all the jurors were writing down `stupid things!' +on their slates, and she could even make out that one of them +didn't know how to spell `stupid,' and that he had to ask his +neighbour to tell him. `A nice muddle their slates'll be in +before the trial's over!' thought Alice. + + One of the jurors had a pencil that squeaked. This of course, +Alice could not stand, and she went round the court and got +behind him, and very soon found an opportunity of taking it +away. She did it so quickly that the poor little juror (it was +Bill, the Lizard) could not make out at all what had become of +it; so, after hunting all about for it, he was obliged to write +with one finger for the rest of the day; and this was of very +little use, as it left no mark on the slate. + + `Herald, read the accusation!' said the King. + + On this the White Rabbit blew three blasts on the trumpet, and +then unrolled the parchment scroll, and read as follows:-- + + `The Queen of Hearts, she made some tarts, + All on a summer day: + The Knave of Hearts, he stole those tarts, + And took them quite away!' + + `Consider your verdict,' the King said to the jury. + + `Not yet, not yet!' the Rabbit hastily interrupted. `There's +a great deal to come before that!' + + `Call the first witness,' said the King; and the White Rabbit +blew three blasts on the trumpet, and called out, `First +witness!' + + The first witness was the Hatter. He came in with a teacup in +one hand and a piece of bread-and-butter in the other. `I beg +pardon, your Majesty,' he began, `for bringing these in: but I +hadn't quite finished my tea when I was sent for.' + + `You ought to have finished,' said the King. `When did you +begin?' + + The Hatter looked at the March Hare, who had followed him into +the court, arm-in-arm with the Dormouse. `Fourteenth of March, I +think it was,' he said. + + `Fifteenth,' said the March Hare. + + `Sixteenth,' added the Dormouse. + + `Write that down,' the King said to the jury, and the jury +eagerly wrote down all three dates on their slates, and then +added them up, and reduced the answer to shillings and pence. + + `Take off your hat,' the King said to the Hatter. + + `It isn't mine,' said the Hatter. + + `Stolen!' the King exclaimed, turning to the jury, who +instantly made a memorandum of the fact. + + `I keep them to sell,' the Hatter added as an explanation; +`I've none of my own. I'm a hatter.' + + Here the Queen put on her spectacles, and began staring at the +Hatter, who turned pale and fidgeted. + + `Give your evidence,' said the King; `and don't be nervous, or +I'll have you executed on the spot.' + + This did not seem to encourage the witness at all: he kept +shifting from one foot to the other, looking uneasily at the +Queen, and in his confusion he bit a large piece out of his +teacup instead of the bread-and-butter. + + Just at this moment Alice felt a very curious sensation, which +puzzled her a good deal until she made out what it was: she was +beginning to grow larger again, and she thought at first she +would get up and leave the court; but on second thoughts she +decided to remain where she was as long as there was room for +her. + + `I wish you wouldn't squeeze so.' said the Dormouse, who was +sitting next to her. `I can hardly breathe.' + + `I can't help it,' said Alice very meekly: `I'm growing.' + + `You've no right to grow here,' said the Dormouse. + + `Don't talk nonsense,' said Alice more boldly: `you know +you're growing too.' + + `Yes, but I grow at a reasonable pace,' said the Dormouse: +`not in that ridiculous fashion.' And he got up very sulkily +and crossed over to the other side of the court. + + All this time the Queen had never left off staring at the +Hatter, and, just as the Dormouse crossed the court, she said to +one of the officers of the court, `Bring me the list of the +singers in the last concert!' on which the wretched Hatter +trembled so, that he shook both his shoes off. + + `Give your evidence,' the King repeated angrily, `or I'll have +you executed, whether you're nervous or not.' + + `I'm a poor man, your Majesty,' the Hatter began, in a +trembling voice, `--and I hadn't begun my tea--not above a week +or so--and what with the bread-and-butter getting so thin--and +the twinkling of the tea--' + + `The twinkling of the what?' said the King. + + `It began with the tea,' the Hatter replied. + + `Of course twinkling begins with a T!' said the King sharply. +`Do you take me for a dunce? Go on!' + + `I'm a poor man,' the Hatter went on, `and most things +twinkled after that--only the March Hare said--' + + `I didn't!' the March Hare interrupted in a great hurry. + + `You did!' said the Hatter. + + `I deny it!' said the March Hare. + + `He denies it,' said the King: `leave out that part.' + + `Well, at any rate, the Dormouse said--' the Hatter went on, +looking anxiously round to see if he would deny it too: but the +Dormouse denied nothing, being fast asleep. + + `After that,' continued the Hatter, `I cut some more bread- +and-butter--' + + `But what did the Dormouse say?' one of the jury asked. + + `That I can't remember,' said the Hatter. + + `You MUST remember,' remarked the King, `or I'll have you +executed.' + + The miserable Hatter dropped his teacup and bread-and-butter, +and went down on one knee. `I'm a poor man, your Majesty,' he +began. + + `You're a very poor speaker,' said the King. + + Here one of the guinea-pigs cheered, and was immediately +suppressed by the officers of the court. (As that is rather a +hard word, I will just explain to you how it was done. They had +a large canvas bag, which tied up at the mouth with strings: +into this they slipped the guinea-pig, head first, and then sat +upon it.) + + `I'm glad I've seen that done,' thought Alice. `I've so often +read in the newspapers, at the end of trials, "There was some +attempts at applause, which was immediately suppressed by the +officers of the court," and I never understood what it meant +till now.' + + `If that's all you know about it, you may stand down,' +continued the King. + + `I can't go no lower,' said the Hatter: `I'm on the floor, as +it is.' + + `Then you may SIT down,' the King replied. + + Here the other guinea-pig cheered, and was suppressed. + + `Come, that finished the guinea-pigs!' thought Alice. `Now we +shall get on better.' + + `I'd rather finish my tea,' said the Hatter, with an anxious +look at the Queen, who was reading the list of singers. + + `You may go,' said the King, and the Hatter hurriedly left the +court, without even waiting to put his shoes on. + + `--and just take his head off outside,' the Queen added to one +of the officers: but the Hatter was out of sight before the +officer could get to the door. + + `Call the next witness!' said the King. + + The next witness was the Duchess's cook. She carried the +pepper-box in her hand, and Alice guessed who it was, even before +she got into the court, by the way the people near the door began +sneezing all at once. + + `Give your evidence,' said the King. + + `Shan't,' said the cook. + + The King looked anxiously at the White Rabbit, who said in a +low voice, `Your Majesty must cross-examine THIS witness.' + + `Well, if I must, I must,' the King said, with a melancholy +air, and, after folding his arms and frowning at the cook till +his eyes were nearly out of sight, he said in a deep voice, `What +are tarts made of?' + + `Pepper, mostly,' said the cook. + + `Treacle,' said a sleepy voice behind her. + + `Collar that Dormouse,' the Queen shrieked out. `Behead that +Dormouse! Turn that Dormouse out of court! Suppress him! Pinch +him! Off with his whiskers!' + + For some minutes the whole court was in confusion, getting the +Dormouse turned out, and, by the time they had settled down +again, the cook had disappeared. + + `Never mind!' said the King, with an air of great relief. +`Call the next witness.' And he added in an undertone to the +Queen, `Really, my dear, YOU must cross-examine the next witness. +It quite makes my forehead ache!' + + Alice watched the White Rabbit as he fumbled over the list, +feeling very curious to see what the next witness would be like, +`--for they haven't got much evidence YET,' she said to herself. +Imagine her surprise, when the White Rabbit read out, at the top +of his shrill little voice, the name `Alice!' + + + + CHAPTER XII + + Alice's Evidence + + + `Here!' cried Alice, quite forgetting in the flurry of the +moment how large she had grown in the last few minutes, and she +jumped up in such a hurry that she tipped over the jury-box with +the edge of her skirt, upsetting all the jurymen on to the heads +of the crowd below, and there they lay sprawling about, reminding +her very much of a globe of goldfish she had accidentally upset +the week before. + + `Oh, I BEG your pardon!' she exclaimed in a tone of great +dismay, and began picking them up again as quickly as she could, +for the accident of the goldfish kept running in her head, and +she had a vague sort of idea that they must be collected at once +and put back into the jury-box, or they would die. + + `The trial cannot proceed,' said the King in a very grave +voice, `until all the jurymen are back in their proper places-- +ALL,' he repeated with great emphasis, looking hard at Alice as +he said do. + + Alice looked at the jury-box, and saw that, in her haste, she +had put the Lizard in head downwards, and the poor little thing +was waving its tail about in a melancholy way, being quite unable +to move. She soon got it out again, and put it right; `not that +it signifies much,' she said to herself; `I should think it +would be QUITE as much use in the trial one way up as the other.' + + As soon as the jury had a little recovered from the shock of +being upset, and their slates and pencils had been found and +handed back to them, they set to work very diligently to write +out a history of the accident, all except the Lizard, who seemed +too much overcome to do anything but sit with its mouth open, +gazing up into the roof of the court. + + `What do you know about this business?' the King said to +Alice. + + `Nothing,' said Alice. + + `Nothing WHATEVER?' persisted the King. + + `Nothing whatever,' said Alice. + + `That's very important,' the King said, turning to the jury. +They were just beginning to write this down on their slates, when +the White Rabbit interrupted: `UNimportant, your Majesty means, +of course,' he said in a very respectful tone, but frowning and +making faces at him as he spoke. + + `UNimportant, of course, I meant,' the King hastily said, and +went on to himself in an undertone, `important--unimportant-- +unimportant--important--' as if he were trying which word +sounded best. + + Some of the jury wrote it down `important,' and some +`unimportant.' Alice could see this, as she was near enough to +look over their slates; `but it doesn't matter a bit,' she +thought to herself. + + At this moment the King, who had been for some time busily +writing in his note-book, cackled out `Silence!' and read out +from his book, `Rule Forty-two. ALL PERSONS MORE THAN A MILE +HIGH TO LEAVE THE COURT.' + + Everybody looked at Alice. + + `I'M not a mile high,' said Alice. + + `You are,' said the King. + + `Nearly two miles high,' added the Queen. + + `Well, I shan't go, at any rate,' said Alice: `besides, +that's not a regular rule: you invented it just now.' + + `It's the oldest rule in the book,' said the King. + + `Then it ought to be Number One,' said Alice. + + The King turned pale, and shut his note-book hastily. +`Consider your verdict,' he said to the jury, in a low, trembling +voice. + + `There's more evidence to come yet, please your Majesty,' said +the White Rabbit, jumping up in a great hurry; `this paper has +just been picked up.' + + `What's in it?' said the Queen. + + `I haven't opened it yet,' said the White Rabbit, `but it seems +to be a letter, written by the prisoner to--to somebody.' + + `It must have been that,' said the King, `unless it was +written to nobody, which isn't usual, you know.' + + `Who is it directed to?' said one of the jurymen. + + `It isn't directed at all,' said the White Rabbit; `in fact, +there's nothing written on the OUTSIDE.' He unfolded the paper +as he spoke, and added `It isn't a letter, after all: it's a set +of verses.' + + `Are they in the prisoner's handwriting?' asked another of +they jurymen. + + `No, they're not,' said the White Rabbit, `and that's the +queerest thing about it.' (The jury all looked puzzled.) + + `He must have imitated somebody else's hand,' said the King. +(The jury all brightened up again.) + + `Please your Majesty,' said the Knave, `I didn't write it, and +they can't prove I did: there's no name signed at the end.' + + `If you didn't sign it,' said the King, `that only makes the +matter worse. You MUST have meant some mischief, or else you'd +have signed your name like an honest man.' + + There was a general clapping of hands at this: it was the +first really clever thing the King had said that day. + + `That PROVES his guilt,' said the Queen. + + `It proves nothing of the sort!' said Alice. `Why, you don't +even know what they're about!' + + `Read them,' said the King. + + The White Rabbit put on his spectacles. `Where shall I begin, +please your Majesty?' he asked. + + `Begin at the beginning,' the King said gravely, `and go on +till you come to the end: then stop.' + + These were the verses the White Rabbit read:-- + + `They told me you had been to her, + And mentioned me to him: + She gave me a good character, + But said I could not swim. + + He sent them word I had not gone + (We know it to be true): + If she should push the matter on, + What would become of you? + + I gave her one, they gave him two, + You gave us three or more; + They all returned from him to you, + Though they were mine before. + + If I or she should chance to be + Involved in this affair, + He trusts to you to set them free, + Exactly as we were. + + My notion was that you had been + (Before she had this fit) + An obstacle that came between + Him, and ourselves, and it. + + Don't let him know she liked them best, + For this must ever be + A secret, kept from all the rest, + Between yourself and me.' + + `That's the most important piece of evidence we've heard yet,' +said the King, rubbing his hands; `so now let the jury--' + + `If any one of them can explain it,' said Alice, (she had +grown so large in the last few minutes that she wasn't a bit +afraid of interrupting him,) `I'll give him sixpence. _I_ don't +believe there's an atom of meaning in it.' + + The jury all wrote down on their slates, `SHE doesn't believe +there's an atom of meaning in it,' but none of them attempted to +explain the paper. + + `If there's no meaning in it,' said the King, `that saves a +world of trouble, you know, as we needn't try to find any. And +yet I don't know,' he went on, spreading out the verses on his +knee, and looking at them with one eye; `I seem to see some +meaning in them, after all. "--SAID I COULD NOT SWIM--" you +can't swim, can you?' he added, turning to the Knave. + + The Knave shook his head sadly. `Do I look like it?' he said. +(Which he certainly did NOT, being made entirely of cardboard.) + + `All right, so far,' said the King, and he went on muttering +over the verses to himself: `"WE KNOW IT TO BE TRUE--" that's +the jury, of course-- "I GAVE HER ONE, THEY GAVE HIM TWO--" why, +that must be what he did with the tarts, you know--' + + `But, it goes on "THEY ALL RETURNED FROM HIM TO YOU,"' said +Alice. + + `Why, there they are!' said the King triumphantly, pointing to +the tarts on the table. `Nothing can be clearer than THAT. +Then again--"BEFORE SHE HAD THIS FIT--" you never had fits, my +dear, I think?' he said to the Queen. + + `Never!' said the Queen furiously, throwing an inkstand at the +Lizard as she spoke. (The unfortunate little Bill had left off +writing on his slate with one finger, as he found it made no +mark; but he now hastily began again, using the ink, that was +trickling down his face, as long as it lasted.) + + `Then the words don't FIT you,' said the King, looking round +the court with a smile. There was a dead silence. + + `It's a pun!' the King added in an offended tone, and +everybody laughed, `Let the jury consider their verdict,' the +King said, for about the twentieth time that day. + + `No, no!' said the Queen. `Sentence first--verdict afterwards.' + + `Stuff and nonsense!' said Alice loudly. `The idea of having +the sentence first!' + + `Hold your tongue!' said the Queen, turning purple. + + `I won't!' said Alice. + + `Off with her head!' the Queen shouted at the top of her voice. +Nobody moved. + + `Who cares for you?' said Alice, (she had grown to her full +size by this time.) `You're nothing but a pack of cards!' + + At this the whole pack rose up into the air, and came flying +down upon her: she gave a little scream, half of fright and half +of anger, and tried to beat them off, and found herself lying on +the bank, with her head in the lap of her sister, who was gently +brushing away some dead leaves that had fluttered down from the +trees upon her face. + + `Wake up, Alice dear!' said her sister; `Why, what a long +sleep you've had!' + + `Oh, I've had such a curious dream!' said Alice, and she told +her sister, as well as she could remember them, all these strange +Adventures of hers that you have just been reading about; and +when she had finished, her sister kissed her, and said, `It WAS a +curious dream, dear, certainly: but now run in to your tea; it's +getting late.' So Alice got up and ran off, thinking while she +ran, as well she might, what a wonderful dream it had been. + + But her sister sat still just as she left her, leaning her +head on her hand, watching the setting sun, and thinking of +little Alice and all her wonderful Adventures, till she too began +dreaming after a fashion, and this was her dream:-- + + First, she dreamed of little Alice herself, and once again the +tiny hands were clasped upon her knee, and the bright eager eyes +were looking up into hers--she could hear the very tones of her +voice, and see that queer little toss of her head to keep back +the wandering hair that WOULD always get into her eyes--and +still as she listened, or seemed to listen, the whole place +around her became alive the strange creatures of her little +sister's dream. + + The long grass rustled at her feet as the White Rabbit hurried +by--the frightened Mouse splashed his way through the +neighbouring pool--she could hear the rattle of the teacups as +the March Hare and his friends shared their never-ending meal, +and the shrill voice of the Queen ordering off her unfortunate +guests to execution--once more the pig-baby was sneezing on the +Duchess's knee, while plates and dishes crashed around it--once +more the shriek of the Gryphon, the squeaking of the Lizard's +slate-pencil, and the choking of the suppressed guinea-pigs, +filled the air, mixed up with the distant sobs of the miserable +Mock Turtle. + + So she sat on, with closed eyes, and half believed herself in +Wonderland, though she knew she had but to open them again, and +all would change to dull reality--the grass would be only +rustling in the wind, and the pool rippling to the waving of the +reeds--the rattling teacups would change to tinkling sheep- +bells, and the Queen's shrill cries to the voice of the shepherd +boy--and the sneeze of the baby, the shriek of the Gryphon, and +all thy other queer noises, would change (she knew) to the +confused clamour of the busy farm-yard--while the lowing of the +cattle in the distance would take the place of the Mock Turtle's +heavy sobs. + + Lastly, she pictured to herself how this same little sister of +hers would, in the after-time, be herself a grown woman; and how +she would keep, through all her riper years, the simple and +loving heart of her childhood: and how she would gather about +her other little children, and make THEIR eyes bright and eager +with many a strange tale, perhaps even with the dream of +Wonderland of long ago: and how she would feel with all their +simple sorrows, and find a pleasure in all their simple joys, +remembering her own child-life, and the happy summer days. + + THE END + \ No newline at end of file diff --git a/src/snappy/testdata/asyoulik.txt b/src/snappy/testdata/asyoulik.txt new file mode 100644 index 000000000..88dc7b60f --- /dev/null +++ b/src/snappy/testdata/asyoulik.txt @@ -0,0 +1,4122 @@ + AS YOU LIKE IT + + + DRAMATIS PERSONAE + + +DUKE SENIOR living in banishment. + +DUKE FREDERICK his brother, an usurper of his dominions. + + +AMIENS | + | lords attending on the banished duke. +JAQUES | + + +LE BEAU a courtier attending upon Frederick. + +CHARLES wrestler to Frederick. + + +OLIVER | + | +JAQUES (JAQUES DE BOYS:) | sons of Sir Rowland de Boys. + | +ORLANDO | + + +ADAM | + | servants to Oliver. +DENNIS | + + +TOUCHSTONE a clown. + +SIR OLIVER MARTEXT a vicar. + + +CORIN | + | shepherds. +SILVIUS | + + +WILLIAM a country fellow in love with Audrey. + + A person representing HYMEN.

My brother Jaques he keeps at school, and + report speaks goldenly of his profit: for my part, + he keeps me rustically at home, or, to speak more + properly, stays me here at home unkept; for call you + that keeping for a gentleman of my birth, that + differs not from the stalling of an ox? His horses + are bred better; for, besides that they are fair + with their feeding, they are taught their manage, + and to that end riders dearly hired: but I, his + brother, gain nothing under him but growth; for the + which his animals on his dunghills are as much + bound to him as I. Besides this nothing that he so + plentifully gives me, the something that nature gave + me his countenance seems to take from me: he lets + me feed with his hinds, bars me the place of a + brother, and, as much as in him lies, mines my + gentility with my education. This is it, Adam, that + grieves me; and the spirit of my father, which I + think is within me, begins to mutiny against this + servitude: I will no longer endure it, though yet I + know no wise remedy how to avoid it. + +ADAM Yonder comes my master, your brother. + +ORLANDO Go apart, Adam, and thou shalt hear how he will + shake me up. + + [Enter OLIVER] + +OLIVER Now, sir! what make you here? + +ORLANDO Nothing: I am not taught to make any thing. + +OLIVER What mar you then, sir? + +ORLANDO Marry, sir, I am helping you to mar that which God + made, a poor unworthy brother of yours, with idleness. + +OLIVER Marry, sir, be better employed, and be naught awhile. + +ORLANDO Shall I keep your hogs and eat husks with them? + What prodigal portion have I spent, that I should + come to such penury? + +OLIVER Know you where your are, sir? + +ORLANDO O, sir, very well; here in your orchard. + +OLIVER Know you before whom, sir? + +ORLANDO Ay, better than him I am before knows me. I know + you are my eldest brother; and, in the gentle + condition of blood, you should so know me. The + courtesy of nations allows you my better, in that + you are the first-born; but the same tradition + takes not away my blood, were there twenty brothers + betwixt us: I have as much of my father in me as + you; albeit, I confess, your coming before me is + nearer to his reverence. + +OLIVER What, boy! + +ORLANDO Come, come, elder brother, you are too young in this. + +OLIVER Wilt thou lay hands on me, villain? + +ORLANDO I am no villain; I am the youngest son of Sir + Rowland de Boys; he was my father, and he is thrice + a villain that says such a father begot villains. + Wert thou not my brother, I would not take this hand + from thy throat till this other had pulled out thy + tongue for saying so: thou hast railed on thyself. + +ADAM Sweet masters, be patient: for your father's + remembrance, be at accord. + +OLIVER Let me go, I say. + +ORLANDO I will not, till I please: you shall hear me. My + father charged you in his will to give me good + education: you have trained me like a peasant, + obscuring and hiding from me all gentleman-like + qualities.

She is at the court, and no + less beloved of her uncle than his own daughter; and + never two ladies loved as they do. + +OLIVER Where will the old duke live? + +CHARLES They say he is already in the forest of Arden, and + a many merry men with him; and there they live like + the old Robin Hood of England: they say many young + gentlemen flock to him every day, and fleet the time + carelessly, as they did in the golden world. + +OLIVER What, you wrestle to-morrow before the new duke? + +CHARLES Marry, do I, sir; and I came to acquaint you with a + matter. I am given, sir, secretly to understand + that your younger brother Orlando hath a disposition + to come in disguised against me to try a fall. + To-morrow, sir, I wrestle for my credit; and he that + escapes me without some broken limb shall acquit him + well. Your brother is but young and tender; and, + for your love, I would be loath to foil him, as I + must, for my own honour, if he come in: therefore, + out of my love to you, I came hither to acquaint you + withal, that either you might stay him from his + intendment or brook such disgrace well as he shall + run into, in that it is a thing of his own search + and altogether against my will. + +OLIVER Charles, I thank thee for thy love to me, which + thou shalt find I will most kindly requite. I had + myself notice of my brother's purpose herein and + have by underhand means laboured to dissuade him from + it, but he is resolute. I'll tell thee, Charles: + it is the stubbornest young fellow of France, full + of ambition, an envious emulator of every man's + good parts, a secret and villanous contriver against + me his natural brother: therefore use thy + discretion; I had as lief thou didst break his neck + as his finger. And thou wert best look to't; for if + thou dost him any slight disgrace or if he do not + mightily grace himself on thee, he will practise + against thee by poison, entrap thee by some + treacherous device and never leave thee till he + hath ta'en thy life by some indirect means or other; + for, I assure thee, and almost with tears I speak + it, there is not one so young and so villanous this + day living. I speak but brotherly of him; but + should I anatomize him to thee as he is, I must + blush and weep and thou must look pale and wonder. + +CHARLES I am heartily glad I came hither to you. If he come + to-morrow, I'll give him his payment: if ever he go + alone again, I'll never wrestle for prize more: and + so God keep your worship! + +OLIVER Farewell, good Charles. + + [Exit CHARLES] + + Now will I stir this gamester: I hope I shall see + an end of him; for my soul, yet I know not why, + hates nothing more than he. Yet he's gentle, never + schooled and yet learned, full of noble device, of + all sorts enchantingly beloved, and indeed so much + in the heart of the world, and especially of my own + people, who best know him, that I am altogether + misprised: but it shall not be so long; this + wrestler shall clear all: nothing remains but that + I kindle the boy thither; which now I'll go about. + + [Exit] + + + + + AS YOU LIKE IT + + +ACT I + + + +SCENE II Lawn before the Duke's palace. + + + [Enter CELIA and ROSALIND] + +CELIA I pray thee, Rosalind, sweet my coz, be merry. + +ROSALIND Dear Celia, I show more mirth than I am mistress of; + and would you yet I were merrier? Unless you could + teach me to forget a banished father, you must not + learn me how to remember any extraordinary pleasure. + +CELIA Herein I see thou lovest me not with the full weight + that I love thee. If my uncle, thy banished father, + had banished thy uncle, the duke my father, so thou + hadst been still with me, I could have taught my + love to take thy father for mine: so wouldst thou, + if the truth of thy love to me were so righteously + tempered as mine is to thee. + +ROSALIND Well, I will forget the condition of my estate, to + rejoice in yours. + +CELIA You know my father hath no child but I, nor none is + like to have: and, truly, when he dies, thou shalt + be his heir, for what he hath taken away from thy + father perforce, I will render thee again in + affection; by mine honour, I will; and when I break + that oath, let me turn monster: therefore, my + sweet Rose, my dear Rose, be merry. + +ROSALIND From henceforth I will, coz, and devise sports. Let + me see; what think you of falling in love? + +CELIA Marry, I prithee, do, to make sport withal: but + love no man in good earnest; nor no further in sport + neither than with safety of a pure blush thou mayst + in honour come off again. + +ROSALIND What shall be our sport, then? + +CELIA Let us sit and mock the good housewife Fortune from + her wheel, that her gifts may henceforth be bestowed equally. + +ROSALIND I would we could do so, for her benefits are + mightily misplaced, and the bountiful blind woman + doth most mistake in her gifts to women. + +CELIA 'Tis true; for those that she makes fair she scarce + makes honest, and those that she makes honest she + makes very ill-favouredly. + +ROSALIND Nay, now thou goest from Fortune's office to + Nature's: Fortune reigns in gifts of the world, + not in the lineaments of Nature. + + [Enter TOUCHSTONE] + +CELIA No? when Nature hath made a fair creature, may she + not by Fortune fall into the fire? Though Nature + hath given us wit to flout at Fortune, hath not + Fortune sent in this fool to cut off the argument? + +ROSALIND Indeed, there is Fortune too hard for Nature, when + Fortune makes Nature's natural the cutter-off of + Nature's wit. + +CELIA Peradventure this is not Fortune's work neither, but + Nature's; who perceiveth our natural wits too dull + to reason of such goddesses and hath sent this + natural for our whetstone; for always the dulness of + the fool is the whetstone of the wits. How now, + wit! whither wander you? + +TOUCHSTONE Mistress, you must come away to your father. + +CELIA Were you made the messenger? + +TOUCHSTONE No, by mine honour, but I was bid to come for you. + +ROSALIND Where learned you that oath, fool? + +TOUCHSTONE Of a certain knight that swore by his honour they + were good pancakes and swore by his honour the + mustard was naught: now I'll stand to it, the + pancakes were naught and the mustard was good, and + yet was not the knight forsworn. + +CELIA How prove you that, in the great heap of your + knowledge? + +ROSALIND Ay, marry, now unmuzzle your wisdom. + +TOUCHSTONE Stand you both forth now: stroke your chins, and + swear by your beards that I am a knave. + +CELIA By our beards, if we had them, thou art. + +TOUCHSTONE By my knavery, if I had it, then I were; but if you + swear by that that is not, you are not forsworn: no + more was this knight swearing by his honour, for he + never had any; or if he had, he had sworn it away + before ever he saw those pancakes or that mustard. + +CELIA Prithee, who is't that thou meanest? + +TOUCHSTONE One that old Frederick, your father, loves. + +CELIA My father's love is enough to honour him: enough! + speak no more of him; you'll be whipped for taxation + one of these days. + +TOUCHSTONE The more pity, that fools may not speak wisely what + wise men do foolishly. + +CELIA By my troth, thou sayest true; for since the little + wit that fools have was silenced, the little foolery + that wise men have makes a great show. Here comes + Monsieur Le Beau. + +ROSALIND With his mouth full of news. + +CELIA Which he will put on us, as pigeons feed their young. + +ROSALIND Then shall we be news-crammed. + +CELIA All the better; we shall be the more marketable. + + [Enter LE BEAU] + + Bon jour, Monsieur Le Beau: what's the news? + +LE BEAU Fair princess, you have lost much good sport. + +CELIA Sport! of what colour? + +LE BEAU What colour, madam! how shall I answer you? + +ROSALIND As wit and fortune will. + +TOUCHSTONE Or as the Destinies decree. + +CELIA Well said: that was laid on with a trowel. + +TOUCHSTONE Nay, if I keep not my rank,-- + +ROSALIND Thou losest thy old smell. + +LE BEAU You amaze me, ladies: I would have told you of good + wrestling, which you have lost the sight of. + +ROSALIND You tell us the manner of the wrestling. + +LE BEAU I will tell you the beginning; and, if it please + your ladyships, you may see the end; for the best is + yet to do; and here, where you are, they are coming + to perform it. + +CELIA Well, the beginning, that is dead and buried. + +LE BEAU There comes an old man and his three sons,-- + +CELIA I could match this beginning with an old tale. + +LE BEAU Three proper young men, of excellent growth and presence. + +ROSALIND With bills on their necks, 'Be it known unto all men + by these presents.' + +LE BEAU The eldest of the three wrestled with Charles, the + duke's wrestler; which Charles in a moment threw him + and broke three of his ribs, that there is little + hope of life in him: so he served the second, and + so the third. Yonder they lie; the poor old man, + their father, making such pitiful dole over them + that all the beholders take his part with weeping. + +ROSALIND Alas! + +TOUCHSTONE But what is the sport, monsieur, that the ladies + have lost? + +LE BEAU Why, this that I speak of. + +TOUCHSTONE Thus men may grow wiser every day: it is the first + time that ever I heard breaking of ribs was sport + for ladies. + +CELIA Or I, I promise thee. + +ROSALIND But is there any else longs to see this broken music + in his sides? is there yet another dotes upon + rib-breaking? Shall we see this wrestling, cousin? + +LE BEAU You must, if you stay here; for here is the place + appointed for the wrestling, and they are ready to + perform it. + +CELIA Yonder, sure, they are coming: let us now stay and see it. + + [Flourish. Enter DUKE FREDERICK, Lords, ORLANDO, + CHARLES, and Attendants] + +DUKE FREDERICK Come on: since the youth will not be entreated, his + own peril on his forwardness. + +ROSALIND Is yonder the man? + +LE BEAU Even he, madam. + +CELIA Alas, he is too young! yet he looks successfully. + +DUKE FREDERICK How now, daughter and cousin! are you crept hither + to see the wrestling? + +ROSALIND Ay, my liege, so please you give us leave. + +DUKE FREDERICK You will take little delight in it, I can tell you; + there is such odds in the man. In pity of the + challenger's youth I would fain dissuade him, but he + will not be entreated. Speak to him, ladies; see if + you can move him. + +CELIA Call him hither, good Monsieur Le Beau. + +DUKE FREDERICK Do so: I'll not be by. + +LE BEAU Monsieur the challenger, the princesses call for you. + +ORLANDO I attend them with all respect and duty. + +ROSALIND Young man, have you challenged Charles the wrestler? + +ORLANDO No, fair princess; he is the general challenger: I + come but in, as others do, to try with him the + strength of my youth. + +CELIA Young gentleman, your spirits are too bold for your + years. You have seen cruel proof of this man's + strength: if you saw yourself with your eyes or + knew yourself with your judgment, the fear of your + adventure would counsel you to a more equal + enterprise. We pray you, for your own sake, to + embrace your own safety and give over this attempt. + +ROSALIND Do, young sir; your reputation shall not therefore + be misprised: we will make it our suit to the duke + that the wrestling might not go forward. + +ORLANDO I beseech you, punish me not with your hard + thoughts; wherein I confess me much guilty, to deny + so fair and excellent ladies any thing. But let + your fair eyes and gentle wishes go with me to my + trial: wherein if I be foiled, there is but one + shamed that was never gracious; if killed, but one + dead that was willing to be so: I shall do my + friends no wrong, for I have none to lament me, the + world no injury, for in it I have nothing; only in + the world I fill up a place, which may be better + supplied when I have made it empty. + +ROSALIND The little strength that I have, I would it were with you. + +CELIA And mine, to eke out hers. + +ROSALIND Fare you well: pray heaven I be deceived in you! + +CELIA Your heart's desires be with you! + +CHARLES Come, where is this young gallant that is so + desirous to lie with his mother earth? + +ORLANDO Ready, sir; but his will hath in it a more modest working. + +DUKE FREDERICK You shall try but one fall. + +CHARLES No, I warrant your grace, you shall not entreat him + to a second, that have so mightily persuaded him + from a first. + +ORLANDO An you mean to mock me after, you should not have + mocked me before: but come your ways. + +ROSALIND Now Hercules be thy speed, young man! + +CELIA I would I were invisible, to catch the strong + fellow by the leg. + + [They wrestle] + +ROSALIND O excellent young man! + +CELIA If I had a thunderbolt in mine eye, I can tell who + should down. + + [Shout. CHARLES is thrown] + +DUKE FREDERICK No more, no more. + +ORLANDO Yes, I beseech your grace: I am not yet well breathed. + +DUKE FREDERICK How dost thou, Charles? + +LE BEAU He cannot speak, my lord. + +DUKE FREDERICK Bear him away. What is thy name, young man? + +ORLANDO Orlando, my liege; the youngest son of Sir Rowland de Boys. + +DUKE FREDERICK I would thou hadst been son to some man else: + The world esteem'd thy father honourable, + But I did find him still mine enemy: + Thou shouldst have better pleased me with this deed, + Hadst thou descended from another house. + But fare thee well; thou art a gallant youth: + I would thou hadst told me of another father. + + [Exeunt DUKE FREDERICK, train, and LE BEAU] + +CELIA Were I my father, coz, would I do this? + +ORLANDO I am more proud to be Sir Rowland's son, + His youngest son; and would not change that calling, + To be adopted heir to Frederick. + +ROSALIND My father loved Sir Rowland as his soul, + And all the world was of my father's mind: + Had I before known this young man his son, + I should have given him tears unto entreaties, + Ere he should thus have ventured. + +CELIA Gentle cousin, + Let us go thank him and encourage him: + My father's rough and envious disposition + Sticks me at heart. Sir, you have well deserved: + If you do keep your promises in love + But justly, as you have exceeded all promise, + Your mistress shall be happy. + +ROSALIND Gentleman, + + [Giving him a chain from her neck] + + Wear this for me, one out of suits with fortune, + That could give more, but that her hand lacks means. + Shall we go, coz? + +CELIA Ay. Fare you well, fair gentleman. + +ORLANDO Can I not say, I thank you? My better parts + Are all thrown down, and that which here stands up + Is but a quintain, a mere lifeless block. + +ROSALIND He calls us back: my pride fell with my fortunes; + I'll ask him what he would. Did you call, sir? + Sir, you have wrestled well and overthrown + More than your enemies. + +CELIA Will you go, coz? + +ROSALIND Have with you. Fare you well. + + [Exeunt ROSALIND and CELIA] + +ORLANDO What passion hangs these weights upon my tongue? + I cannot speak to her, yet she urged conference. + O poor Orlando, thou art overthrown! + Or Charles or something weaker masters thee. + + [Re-enter LE BEAU] + +LE BEAU Good sir, I do in friendship counsel you + To leave this place. Albeit you have deserved + High commendation, true applause and love, + Yet such is now the duke's condition + That he misconstrues all that you have done. + The duke is humorous; what he is indeed, + More suits you to conceive than I to speak of. + +ORLANDO I thank you, sir: and, pray you, tell me this: + Which of the two was daughter of the duke + That here was at the wrestling? + +LE BEAU Neither his daughter, if we judge by manners; + But yet indeed the lesser is his daughter + The other is daughter to the banish'd duke, + And here detain'd by her usurping uncle, + To keep his daughter company; whose loves + Are dearer than the natural bond of sisters. + But I can tell you that of late this duke + Hath ta'en displeasure 'gainst his gentle niece, + Grounded upon no other argument + But that the people praise her for her virtues + And pity her for her good father's sake; + And, on my life, his malice 'gainst the lady + Will suddenly break forth. Sir, fare you well: + Hereafter, in a better world than this, + I shall desire more love and knowledge of you. + +ORLANDO I rest much bounden to you: fare you well. + + [Exit LE BEAU] + + Thus must I from the smoke into the smother; + From tyrant duke unto a tyrant brother: + But heavenly Rosalind! + + [Exit] + + + + + AS YOU LIKE IT + + +ACT I + + + +SCENE III A room in the palace. + + + [Enter CELIA and ROSALIND] + +CELIA Why, cousin! why, Rosalind! Cupid have mercy! not a word? + +ROSALIND Not one to throw at a dog. + +CELIA No, thy words are too precious to be cast away upon + curs; throw some of them at me; come, lame me with reasons. + +ROSALIND Then there were two cousins laid up; when the one + should be lamed with reasons and the other mad + without any. + +CELIA But is all this for your father? + +ROSALIND No, some of it is for my child's father. O, how + full of briers is this working-day world! + +CELIA They are but burs, cousin, thrown upon thee in + holiday foolery: if we walk not in the trodden + paths our very petticoats will catch them. + +ROSALIND I could shake them off my coat: these burs are in my heart. + +CELIA Hem them away. + +ROSALIND I would try, if I could cry 'hem' and have him. + +CELIA Come, come, wrestle with thy affections. + +ROSALIND O, they take the part of a better wrestler than myself! + +CELIA O, a good wish upon you! you will try in time, in + despite of a fall. But, turning these jests out of + service, let us talk in good earnest: is it + possible, on such a sudden, you should fall into so + strong a liking with old Sir Rowland's youngest son? + +ROSALIND The duke my father loved his father dearly. + +CELIA Doth it therefore ensue that you should love his son + dearly? By this kind of chase, I should hate him, + for my father hated his father dearly; yet I hate + not Orlando. + +ROSALIND No, faith, hate him not, for my sake. + +CELIA Why should I not? doth he not deserve well? + +ROSALIND Let me love him for that, and do you love him + because I do. Look, here comes the duke. + +CELIA With his eyes full of anger. + + [Enter DUKE FREDERICK, with Lords] + +DUKE FREDERICK Mistress, dispatch you with your safest haste + And get you from our court. + +ROSALIND Me, uncle? + +DUKE FREDERICK You, cousin + Within these ten days if that thou be'st found + So near our public court as twenty miles, + Thou diest for it. + +ROSALIND I do beseech your grace, + Let me the knowledge of my fault bear with me: + If with myself I hold intelligence + Or have acquaintance with mine own desires, + If that I do not dream or be not frantic,-- + As I do trust I am not--then, dear uncle, + Never so much as in a thought unborn + Did I offend your highness. + +DUKE FREDERICK Thus do all traitors: + If their purgation did consist in words, + They are as innocent as grace itself: + Let it suffice thee that I trust thee not. + +ROSALIND Yet your mistrust cannot make me a traitor: + Tell me whereon the likelihood depends. + +DUKE FREDERICK Thou art thy father's daughter; there's enough. + +ROSALIND So was I when your highness took his dukedom; + So was I when your highness banish'd him: + Treason is not inherited, my lord; + Or, if we did derive it from our friends, + What's that to me? my father was no traitor: + Then, good my liege, mistake me not so much + To think my poverty is treacherous. + +CELIA Dear sovereign, hear me speak. + +DUKE FREDERICK Ay, Celia; we stay'd her for your sake, + Else had she with her father ranged along. + +CELIA I did not then entreat to have her stay; + It was your pleasure and your own remorse: + I was too young that time to value her; + But now I know her: if she be a traitor, + Why so am I; we still have slept together, + Rose at an instant, learn'd, play'd, eat together, + And wheresoever we went, like Juno's swans, + Still we went coupled and inseparable. + +DUKE FREDERICK She is too subtle for thee; and her smoothness, + Her very silence and her patience + Speak to the people, and they pity her. + Thou art a fool: she robs thee of thy name; + And thou wilt show more bright and seem more virtuous + When she is gone. Then open not thy lips: + Firm and irrevocable is my doom + Which I have pass'd upon her; she is banish'd. + +CELIA Pronounce that sentence then on me, my liege: + I cannot live out of her company. + +DUKE FREDERICK You are a fool. You, niece, provide yourself: + If you outstay the time, upon mine honour, + And in the greatness of my word, you die. + + [Exeunt DUKE FREDERICK and Lords] + +CELIA O my poor Rosalind, whither wilt thou go? + Wilt thou change fathers? I will give thee mine. + I charge thee, be not thou more grieved than I am. + +ROSALIND I have more cause. + +CELIA Thou hast not, cousin; + Prithee be cheerful: know'st thou not, the duke + Hath banish'd me, his daughter? + +ROSALIND That he hath not. + +CELIA No, hath not? Rosalind lacks then the love + Which teacheth thee that thou and I am one: + Shall we be sunder'd? shall we part, sweet girl? + No: let my father seek another heir. + Therefore devise with me how we may fly, + Whither to go and what to bear with us; + And do not seek to take your change upon you, + To bear your griefs yourself and leave me out; + For, by this heaven, now at our sorrows pale, + Say what thou canst, I'll go along with thee. + +ROSALIND Why, whither shall we go? + +CELIA To seek my uncle in the forest of Arden. + +ROSALIND Alas, what danger will it be to us, + Maids as we are, to travel forth so far! + Beauty provoketh thieves sooner than gold. + +CELIA I'll put myself in poor and mean attire + And with a kind of umber smirch my face; + The like do you: so shall we pass along + And never stir assailants. + +ROSALIND Were it not better, + Because that I am more than common tall, + That I did suit me all points like a man? + A gallant curtle-axe upon my thigh, + A boar-spear in my hand; and--in my heart + Lie there what hidden woman's fear there will-- + We'll have a swashing and a martial outside, + As many other mannish cowards have + That do outface it with their semblances. + +CELIA What shall I call thee when thou art a man? + +ROSALIND I'll have no worse a name than Jove's own page; + And therefore look you call me Ganymede. + But what will you be call'd? + +CELIA Something that hath a reference to my state + No longer Celia, but Aliena. + +ROSALIND But, cousin, what if we assay'd to steal + The clownish fool out of your father's court? + Would he not be a comfort to our travel? + +CELIA He'll go along o'er the wide world with me; + Leave me alone to woo him. Let's away, + And get our jewels and our wealth together, + Devise the fittest time and safest way + To hide us from pursuit that will be made + After my flight.

I like this place. + And willingly could waste my time in it. + +CORIN Assuredly the thing is to be sold: + Go with me: if you like upon report + The soil, the profit and this kind of life, + I will your very faithful feeder be + And buy it with your gold right suddenly. + + [Exeunt] + + + + + AS YOU LIKE IT + + +ACT II + + + +SCENE V The Forest. + + + [Enter AMIENS, JAQUES, and others] + + SONG. +AMIENS Under the greenwood tree + Who loves to lie with me, + And turn his merry note + Unto the sweet bird's throat, + Come hither, come hither, come hither: + Here shall he see No enemy + But winter and rough weather. + +JAQUES More, more, I prithee, more. + +AMIENS It will make you melancholy, Monsieur Jaques. + +JAQUES I thank it.

Come, more; another stanzo: call you 'em stanzos? + +AMIENS What you will, Monsieur Jaques. + +JAQUES Nay, I care not for their names; they owe me + nothing. Will you sing? + +AMIENS More at your request than to please myself. + +JAQUES Well then, if ever I thank any man, I'll thank you; + but that they call compliment is like the encounter + of two dog-apes, and when a man thanks me heartily, + methinks I have given him a penny and he renders me + the beggarly thanks. Come, sing; and you that will + not, hold your tongues. + +AMIENS Well, I'll end the song. Sirs, cover the while; the + duke will drink under this tree. He hath been all + this day to look you. + +JAQUES And I have been all this day to avoid him.

Enter DUKE SENIOR, AMIENS, and + Lords like outlaws] + +DUKE SENIOR I think he be transform'd into a beast; + For I can no where find him like a man. + +First Lord My lord, he is but even now gone hence: + Here was he merry, hearing of a song. + +DUKE SENIOR If he, compact of jars, grow musical, + We shall have shortly discord in the spheres. + Go, seek him: tell him I would speak with him. + + [Enter JAQUES] + +First Lord He saves my labour by his own approach. + +DUKE SENIOR Why, how now, monsieur! what a life is this, + That your poor friends must woo your company? + What, you look merrily! + +JAQUES A fool, a fool! I met a fool i' the forest, + A motley fool; a miserable world! + As I do live by food, I met a fool + Who laid him down and bask'd him in the sun, + And rail'd on Lady Fortune in good terms, + In good set terms and yet a motley fool. + 'Good morrow, fool,' quoth I. 'No, sir,' quoth he, + 'Call me not fool till heaven hath sent me fortune:' + And then he drew a dial from his poke, + And, looking on it with lack-lustre eye, + Says very wisely, 'It is ten o'clock: + Thus we may see,' quoth he, 'how the world wags: + 'Tis but an hour ago since it was nine, + And after one hour more 'twill be eleven; + And so, from hour to hour, we ripe and ripe, + And then, from hour to hour, we rot and rot; + And thereby hangs a tale.' When I did hear + The motley fool thus moral on the time, + My lungs began to crow like chanticleer, + That fools should be so deep-contemplative, + And I did laugh sans intermission + An hour by his dial. O noble fool! + A worthy fool! Motley's the only wear. + +DUKE SENIOR What fool is this? + +JAQUES O worthy fool! One that hath been a courtier, + And says, if ladies be but young and fair, + They have the gift to know it: and in his brain, + Which is as dry as the remainder biscuit + After a voyage, he hath strange places cramm'd + With observation, the which he vents + In mangled forms. O that I were a fool! + I am ambitious for a motley coat. + +DUKE SENIOR Thou shalt have one. + +JAQUES It is my only suit; + Provided that you weed your better judgments + Of all opinion that grows rank in them + That I am wise. I must have liberty + Withal, as large a charter as the wind, + To blow on whom I please; for so fools have; + And they that are most galled with my folly, + They most must laugh. And why, sir, must they so? + The 'why' is plain as way to parish church: + He that a fool doth very wisely hit + Doth very foolishly, although he smart, + Not to seem senseless of the bob: if not, + The wise man's folly is anatomized + Even by the squandering glances of the fool. + Invest me in my motley; give me leave + To speak my mind, and I will through and through + Cleanse the foul body of the infected world, + If they will patiently receive my medicine. + +DUKE SENIOR Fie on thee! I can tell what thou wouldst do. + +JAQUES What, for a counter, would I do but good? + +DUKE SENIOR Most mischievous foul sin, in chiding sin: + For thou thyself hast been a libertine, + As sensual as the brutish sting itself; + And all the embossed sores and headed evils, + That thou with licence of free foot hast caught, + Wouldst thou disgorge into the general world. + +JAQUES Why, who cries out on pride, + That can therein tax any private party? + Doth it not flow as hugely as the sea, + Till that the weary very means do ebb? + What woman in the city do I name, + When that I say the city-woman bears + The cost of princes on unworthy shoulders? + Who can come in and say that I mean her, + When such a one as she such is her neighbour? + Or what is he of basest function + That says his bravery is not of my cost, + Thinking that I mean him, but therein suits + His folly to the mettle of my speech? + There then; how then? what then? Let me see wherein + My tongue hath wrong'd him: if it do him right, + Then he hath wrong'd himself; if he be free, + Why then my taxing like a wild-goose flies, + Unclaim'd of any man. But who comes here? + + [Enter ORLANDO, with his sword drawn] + +ORLANDO Forbear, and eat no more. + +JAQUES Why, I have eat none yet. + +ORLANDO Nor shalt not, till necessity be served. + +JAQUES Of what kind should this cock come of? + +DUKE SENIOR Art thou thus bolden'd, man, by thy distress, + Or else a rude despiser of good manners, + That in civility thou seem'st so empty? + +ORLANDO You touch'd my vein at first: the thorny point + Of bare distress hath ta'en from me the show + Of smooth civility: yet am I inland bred + And know some nurture. But forbear, I say: + He dies that touches any of this fruit + Till I and my affairs are answered. + +JAQUES An you will not be answered with reason, I must die. + +DUKE SENIOR What would you have? Your gentleness shall force + More than your force move us to gentleness. + +ORLANDO I almost die for food; and let me have it. + +DUKE SENIOR Sit down and feed, and welcome to our table. + +ORLANDO Speak you so gently? Pardon me, I pray you: + I thought that all things had been savage here; + And therefore put I on the countenance + Of stern commandment. But whate'er you are + That in this desert inaccessible, + Under the shade of melancholy boughs, + Lose and neglect the creeping hours of time + If ever you have look'd on better days, + If ever been where bells have knoll'd to church, + If ever sat at any good man's feast, + If ever from your eyelids wiped a tear + And know what 'tis to pity and be pitied, + Let gentleness my strong enforcement be: + In the which hope I blush, and hide my sword. + +DUKE SENIOR True is it that we have seen better days, + And have with holy bell been knoll'd to church + And sat at good men's feasts and wiped our eyes + Of drops that sacred pity hath engender'd: + And therefore sit you down in gentleness + And take upon command what help we have + That to your wanting may be minister'd. + +ORLANDO Then but forbear your food a little while, + Whiles, like a doe, I go to find my fawn + And give it food. There is an old poor man, + Who after me hath many a weary step + Limp'd in pure love: till he be first sufficed, + Oppress'd with two weak evils, age and hunger, + I will not touch a bit. + +DUKE SENIOR Go find him out, + And we will nothing waste till you return. + +ORLANDO I thank ye; and be blest for your good comfort! + + [Exit] + +DUKE SENIOR Thou seest we are not all alone unhappy: + This wide and universal theatre + Presents more woeful pageants than the scene + Wherein we play in. + +JAQUES All the world's a stage, + And all the men and women merely players: + They have their exits and their entrances; + And one man in his time plays many parts, + His acts being seven ages. At first the infant, + Mewling and puking in the nurse's arms. + And then the whining school-boy, with his satchel + And shining morning face, creeping like snail + Unwillingly to school. And then the lover, + Sighing like furnace, with a woeful ballad + Made to his mistress' eyebrow. Then a soldier, + Full of strange oaths and bearded like the pard, + Jealous in honour, sudden and quick in quarrel, + Seeking the bubble reputation + Even in the cannon's mouth. And then the justice, + In fair round belly with good capon lined, + With eyes severe and beard of formal cut, + Full of wise saws and modern instances; + And so he plays his part. The sixth age shifts + Into the lean and slipper'd pantaloon, + With spectacles on nose and pouch on side, + His youthful hose, well saved, a world too wide + For his shrunk shank; and his big manly voice, + Turning again toward childish treble, pipes + And whistles in his sound. Last scene of all, + That ends this strange eventful history, + Is second childishness and mere oblivion, + Sans teeth, sans eyes, sans taste, sans everything. + + [Re-enter ORLANDO, with ADAM] + +DUKE SENIOR Welcome.

In respect that it is solitary, I + like it very well; but in respect that it is + private, it is a very vile life. Now, in respect it + is in the fields, it pleaseth me well; but in + respect it is not in the court, it is tedious. As + is it a spare life, look you, it fits my humour well; + but as there is no more plenty in it, it goes much + against my stomach. Hast any philosophy in thee, shepherd? + +CORIN No more but that I know the more one sickens the + worse at ease he is; and that he that wants money, + means and content is without three good friends; + that the property of rain is to wet and fire to + burn; that good pasture makes fat sheep, and that a + great cause of the night is lack of the sun; that + he that hath learned no wit by nature nor art may + complain of good breeding or comes of a very dull kindred. + +TOUCHSTONE Such a one is a natural philosopher. Wast ever in + court, shepherd? + +CORIN No, truly. + +TOUCHSTONE Then thou art damned. + +CORIN Nay, I hope. + +TOUCHSTONE Truly, thou art damned like an ill-roasted egg, all + on one side. + +CORIN For not being at court? Your reason. + +TOUCHSTONE Why, if thou never wast at court, thou never sawest + good manners; if thou never sawest good manners, + then thy manners must be wicked; and wickedness is + sin, and sin is damnation. Thou art in a parlous + state, shepherd. + +CORIN Not a whit, Touchstone: those that are good manners + at the court are as ridiculous in the country as the + behavior of the country is most mockable at the + court. You told me you salute not at the court, but + you kiss your hands: that courtesy would be + uncleanly, if courtiers were shepherds. + +TOUCHSTONE Instance, briefly; come, instance. + +CORIN Why, we are still handling our ewes, and their + fells, you know, are greasy. + +TOUCHSTONE Why, do not your courtier's hands sweat? and is not + the grease of a mutton as wholesome as the sweat of + a man? Shallow, shallow. A better instance, I say; come. + +CORIN Besides, our hands are hard. + +TOUCHSTONE Your lips will feel them the sooner. Shallow again. + A more sounder instance, come. + +CORIN And they are often tarred over with the surgery of + our sheep: and would you have us kiss tar? The + courtier's hands are perfumed with civet. + +TOUCHSTONE Most shallow man! thou worms-meat, in respect of a + good piece of flesh indeed! Learn of the wise, and + perpend: civet is of a baser birth than tar, the + very uncleanly flux of a cat. Mend the instance, shepherd. + +CORIN You have too courtly a wit for me: I'll rest. + +TOUCHSTONE Wilt thou rest damned? God help thee, shallow man! + God make incision in thee! thou art raw. + +CORIN Sir, I am a true labourer: I earn that I eat, get + that I wear, owe no man hate, envy no man's + happiness, glad of other men's good, content with my + harm, and the greatest of my pride is to see my ewes + graze and my lambs suck. + +TOUCHSTONE That is another simple sin in you, to bring the ewes + and the rams together and to offer to get your + living by the copulation of cattle; to be bawd to a + bell-wether, and to betray a she-lamb of a + twelvemonth to a crooked-pated, old, cuckoldly ram, + out of all reasonable match. If thou beest not + damned for this, the devil himself will have no + shepherds; I cannot see else how thou shouldst + 'scape. + +CORIN Here comes young Master Ganymede, my new mistress's brother. + + [Enter ROSALIND, with a paper, reading] + +ROSALIND From the east to western Ind, + No jewel is like Rosalind. + Her worth, being mounted on the wind, + Through all the world bears Rosalind. + All the pictures fairest lined + Are but black to Rosalind. + Let no fair be kept in mind + But the fair of Rosalind. + +TOUCHSTONE I'll rhyme you so eight years together, dinners and + suppers and sleeping-hours excepted: it is the + right butter-women's rank to market. + +ROSALIND Out, fool! + +TOUCHSTONE For a taste: + If a hart do lack a hind, + Let him seek out Rosalind. + If the cat will after kind, + So be sure will Rosalind. + Winter garments must be lined, + So must slender Rosalind. + They that reap must sheaf and bind; + Then to cart with Rosalind. + Sweetest nut hath sourest rind, + Such a nut is Rosalind. + He that sweetest rose will find + Must find love's prick and Rosalind. + This is the very false gallop of verses: why do you + infect yourself with them? + +ROSALIND Peace, you dull fool! I found them on a tree. + +TOUCHSTONE Truly, the tree yields bad fruit. + +ROSALIND I'll graff it with you, and then I shall graff it + with a medlar: then it will be the earliest fruit + i' the country; for you'll be rotten ere you be half + ripe, and that's the right virtue of the medlar. + +TOUCHSTONE You have said; but whether wisely or no, let the + forest judge. + + [Enter CELIA, with a writing] + +ROSALIND Peace! Here comes my sister, reading: stand aside. + +CELIA [Reads] + + Why should this a desert be? + For it is unpeopled? No: + Tongues I'll hang on every tree, + That shall civil sayings show: + Some, how brief the life of man + Runs his erring pilgrimage, + That the stretching of a span + Buckles in his sum of age; + Some, of violated vows + 'Twixt the souls of friend and friend: + But upon the fairest boughs, + Or at every sentence end, + Will I Rosalinda write, + Teaching all that read to know + The quintessence of every sprite + Heaven would in little show. + Therefore Heaven Nature charged + That one body should be fill'd + With all graces wide-enlarged: + Nature presently distill'd + Helen's cheek, but not her heart, + Cleopatra's majesty, + Atalanta's better part, + Sad Lucretia's modesty. + Thus Rosalind of many parts + By heavenly synod was devised, + Of many faces, eyes and hearts, + To have the touches dearest prized. + Heaven would that she these gifts should have, + And I to live and die her slave. + +ROSALIND O most gentle pulpiter! what tedious homily of love + have you wearied your parishioners withal, and never + cried 'Have patience, good people!' + +CELIA How now! back, friends! Shepherd, go off a little. + Go with him, sirrah. + +TOUCHSTONE Come, shepherd, let us make an honourable retreat; + though not with bag and baggage, yet with scrip and scrippage. + + [Exeunt CORIN and TOUCHSTONE] + +CELIA Didst thou hear these verses? + +ROSALIND O, yes, I heard them all, and more too; for some of + them had in them more feet than the verses would bear. + +CELIA That's no matter: the feet might bear the verses. + +ROSALIND Ay, but the feet were lame and could not bear + themselves without the verse and therefore stood + lamely in the verse. + +CELIA But didst thou hear without wondering how thy name + should be hanged and carved upon these trees? + +ROSALIND I was seven of the nine days out of the wonder + before you came; for look here what I found on a + palm-tree. I was never so be-rhymed since + Pythagoras' time, that I was an Irish rat, which I + can hardly remember. + +CELIA Trow you who hath done this? + +ROSALIND Is it a man? + +CELIA And a chain, that you once wore, about his neck. + Change you colour? + +ROSALIND I prithee, who? + +CELIA O Lord, Lord! it is a hard matter for friends to + meet; but mountains may be removed with earthquakes + and so encounter. + +ROSALIND Nay, but who is it? + +CELIA Is it possible? + +ROSALIND Nay, I prithee now with most petitionary vehemence, + tell me who it is. + +CELIA O wonderful, wonderful, and most wonderful + wonderful! and yet again wonderful, and after that, + out of all hooping! + +ROSALIND Good my complexion! dost thou think, though I am + caparisoned like a man, I have a doublet and hose in + my disposition? One inch of delay more is a + South-sea of discovery; I prithee, tell me who is it + quickly, and speak apace. I would thou couldst + stammer, that thou mightst pour this concealed man + out of thy mouth, as wine comes out of a narrow- + mouthed bottle, either too much at once, or none at + all. I prithee, take the cork out of thy mouth that + may drink thy tidings. + +CELIA So you may put a man in your belly. + +ROSALIND Is he of God's making? What manner of man? Is his + head worth a hat, or his chin worth a beard? + +CELIA Nay, he hath but a little beard. + +ROSALIND Why, God will send more, if the man will be + thankful: let me stay the growth of his beard, if + thou delay me not the knowledge of his chin. + +CELIA It is young Orlando, that tripped up the wrestler's + heels and your heart both in an instant. + +ROSALIND Nay, but the devil take mocking: speak, sad brow and + true maid. + +CELIA I' faith, coz, 'tis he. + +ROSALIND Orlando? + +CELIA Orlando. + +ROSALIND Alas the day! what shall I do with my doublet and + hose? What did he when thou sawest him? What said + he? How looked he? Wherein went he? What makes + him here? Did he ask for me? Where remains he? + How parted he with thee? and when shalt thou see + him again? Answer me in one word. + +CELIA You must borrow me Gargantua's mouth first: 'tis a + word too great for any mouth of this age's size. To + say ay and no to these particulars is more than to + answer in a catechism. + +ROSALIND But doth he know that I am in this forest and in + man's apparel? Looks he as freshly as he did the + day he wrestled? + +CELIA It is as easy to count atomies as to resolve the + propositions of a lover; but take a taste of my + finding him, and relish it with good observance. + I found him under a tree, like a dropped acorn. + +ROSALIND It may well be called Jove's tree, when it drops + forth such fruit. + +CELIA Give me audience, good madam. + +ROSALIND Proceed. + +CELIA There lay he, stretched along, like a wounded knight. + +ROSALIND Though it be pity to see such a sight, it well + becomes the ground. + +CELIA Cry 'holla' to thy tongue, I prithee; it curvets + unseasonably. He was furnished like a hunter. + +ROSALIND O, ominous! he comes to kill my heart. + +CELIA I would sing my song without a burden: thou bringest + me out of tune. + +ROSALIND Do you not know I am a woman? when I think, I must + speak. Sweet, say on. + +CELIA You bring me out. Soft! comes he not here? + + [Enter ORLANDO and JAQUES] + +ROSALIND 'Tis he: slink by, and note him. + +JAQUES I thank you for your company; but, good faith, I had + as lief have been myself alone. + +ORLANDO And so had I; but yet, for fashion sake, I thank you + too for your society. + +JAQUES God be wi' you: let's meet as little as we can. + +ORLANDO I do desire we may be better strangers. + +JAQUES I pray you, mar no more trees with writing + love-songs in their barks. + +ORLANDO I pray you, mar no more of my verses with reading + them ill-favouredly. + +JAQUES Rosalind is your love's name? + +ORLANDO Yes, just. + +JAQUES I do not like her name. + +ORLANDO There was no thought of pleasing you when she was + christened. + +JAQUES What stature is she of? + +ORLANDO Just as high as my heart. + +JAQUES You are full of pretty answers. Have you not been + acquainted with goldsmiths' wives, and conned them + out of rings? + +ORLANDO Not so; but I answer you right painted cloth, from + whence you have studied your questions. + +JAQUES You have a nimble wit: I think 'twas made of + Atalanta's heels. Will you sit down with me? and + we two will rail against our mistress the world and + all our misery. + +ORLANDO I will chide no breather in the world but myself, + against whom I know most faults. + +JAQUES The worst fault you have is to be in love. + +ORLANDO 'Tis a fault I will not change for your best virtue. + I am weary of you. + +JAQUES By my troth, I was seeking for a fool when I found + you. + +ORLANDO He is drowned in the brook: look but in, and you + shall see him. + +JAQUES There I shall see mine own figure. + +ORLANDO Which I take to be either a fool or a cipher. + +JAQUES I'll tarry no longer with you: farewell, good + Signior Love. + +ORLANDO I am glad of your departure: adieu, good Monsieur + Melancholy. + + [Exit JAQUES] + +ROSALIND [Aside to CELIA] I will speak to him, like a saucy + lackey and under that habit play the knave with him. + Do you hear, forester? + +ORLANDO Very well: what would you? + +ROSALIND I pray you, what is't o'clock? + +ORLANDO You should ask me what time o' day: there's no clock + in the forest. + +ROSALIND Then there is no true lover in the forest; else + sighing every minute and groaning every hour would + detect the lazy foot of Time as well as a clock. + +ORLANDO And why not the swift foot of Time? had not that + been as proper? + +ROSALIND By no means, sir: Time travels in divers paces with + divers persons. I'll tell you who Time ambles + withal, who Time trots withal, who Time gallops + withal and who he stands still withal. + +ORLANDO I prithee, who doth he trot withal? + +ROSALIND Marry, he trots hard with a young maid between the + contract of her marriage and the day it is + solemnized: if the interim be but a se'nnight, + Time's pace is so hard that it seems the length of + seven year. + +ORLANDO Who ambles Time withal? + +ROSALIND With a priest that lacks Latin and a rich man that + hath not the gout, for the one sleeps easily because + he cannot study, and the other lives merrily because + he feels no pain, the one lacking the burden of lean + and wasteful learning, the other knowing no burden + of heavy tedious penury; these Time ambles withal. + +ORLANDO Who doth he gallop withal? + +ROSALIND With a thief to the gallows, for though he go as + softly as foot can fall, he thinks himself too soon there. + +ORLANDO Who stays it still withal? + +ROSALIND With lawyers in the vacation, for they sleep between + term and term and then they perceive not how Time moves. + +ORLANDO Where dwell you, pretty youth? + +ROSALIND With this shepherdess, my sister; here in the + skirts of the forest, like fringe upon a petticoat. + +ORLANDO Are you native of this place? + +ROSALIND As the cony that you see dwell where she is kindled. + +ORLANDO Your accent is something finer than you could + purchase in so removed a dwelling. + +ROSALIND I have been told so of many: but indeed an old + religious uncle of mine taught me to speak, who was + in his youth an inland man; one that knew courtship + too well, for there he fell in love. I have heard + him read many lectures against it, and I thank God + I am not a woman, to be touched with so many + giddy offences as he hath generally taxed their + whole sex withal. + +ORLANDO Can you remember any of the principal evils that he + laid to the charge of women? + +ROSALIND There were none principal; they were all like one + another as half-pence are, every one fault seeming + monstrous till his fellow fault came to match it. + +ORLANDO I prithee, recount some of them. + +ROSALIND No, I will not cast away my physic but on those that + are sick. There is a man haunts the forest, that + abuses our young plants with carving 'Rosalind' on + their barks; hangs odes upon hawthorns and elegies + on brambles, all, forsooth, deifying the name of + Rosalind: if I could meet that fancy-monger I would + give him some good counsel, for he seems to have the + quotidian of love upon him. + +ORLANDO I am he that is so love-shaked: I pray you tell me + your remedy. + +ROSALIND There is none of my uncle's marks upon you: he + taught me how to know a man in love; in which cage + of rushes I am sure you are not prisoner. + +ORLANDO What were his marks? + +ROSALIND A lean cheek, which you have not, a blue eye and + sunken, which you have not, an unquestionable + spirit, which you have not, a beard neglected, + which you have not; but I pardon you for that, for + simply your having in beard is a younger brother's + revenue: then your hose should be ungartered, your + bonnet unbanded, your sleeve unbuttoned, your shoe + untied and every thing about you demonstrating a + careless desolation; but you are no such man; you + are rather point-device in your accoutrements as + loving yourself than seeming the lover of any other. + +ORLANDO Fair youth, I would I could make thee believe I love. + +ROSALIND Me believe it! you may as soon make her that you + love believe it; which, I warrant, she is apter to + do than to confess she does: that is one of the + points in the which women still give the lie to + their consciences. But, in good sooth, are you he + that hangs the verses on the trees, wherein Rosalind + is so admired? + +ORLANDO I swear to thee, youth, by the white hand of + Rosalind, I am that he, that unfortunate he. + +ROSALIND But are you so much in love as your rhymes speak? + +ORLANDO Neither rhyme nor reason can express how much. + +ROSALIND Love is merely a madness, and, I tell you, deserves + as well a dark house and a whip as madmen do: and + the reason why they are not so punished and cured + is, that the lunacy is so ordinary that the whippers + are in love too. Yet I profess curing it by counsel. + +ORLANDO Did you ever cure any so? + +ROSALIND Yes, one, and in this manner. He was to imagine me + his love, his mistress; and I set him every day to + woo me: at which time would I, being but a moonish + youth, grieve, be effeminate, changeable, longing + and liking, proud, fantastical, apish, shallow, + inconstant, full of tears, full of smiles, for every + passion something and for no passion truly any + thing, as boys and women are for the most part + cattle of this colour; would now like him, now loathe + him; then entertain him, then forswear him; now weep + for him, then spit at him; that I drave my suitor + from his mad humour of love to a living humour of + madness; which was, to forswear the full stream of + the world, and to live in a nook merely monastic. + And thus I cured him; and this way will I take upon + me to wash your liver as clean as a sound sheep's + heart, that there shall not be one spot of love in't. + +ORLANDO I would not be cured, youth. + +ROSALIND I would cure you, if you would but call me Rosalind + and come every day to my cote and woo me. + +ORLANDO Now, by the faith of my love, I will: tell me + where it is. + +ROSALIND Go with me to it and I'll show it you and by the way + you shall tell me where in the forest you live. + Will you go? + +ORLANDO With all my heart, good youth. + +ROSALIND Nay you must call me Rosalind. Come, sister, will you go? + + [Exeunt] + + + + + AS YOU LIKE IT + + +ACT III + + + +SCENE III The forest. + + + [Enter TOUCHSTONE and AUDREY; JAQUES behind] + +TOUCHSTONE Come apace, good Audrey: I will fetch up your + goats, Audrey. And how, Audrey? am I the man yet? + doth my simple feature content you? + +AUDREY Your features! Lord warrant us! what features! + +TOUCHSTONE I am here with thee and thy goats, as the most + capricious poet, honest Ovid, was among the Goths. + +JAQUES [Aside] O knowledge ill-inhabited, worse than Jove + in a thatched house! + +TOUCHSTONE When a man's verses cannot be understood, nor a + man's good wit seconded with the forward child + Understanding, it strikes a man more dead than a + great reckoning in a little room. Truly, I would + the gods had made thee poetical. + +AUDREY I do not know what 'poetical' is: is it honest in + deed and word? is it a true thing? + +TOUCHSTONE No, truly; for the truest poetry is the most + feigning; and lovers are given to poetry, and what + they swear in poetry may be said as lovers they do feign. + +AUDREY Do you wish then that the gods had made me poetical? + +TOUCHSTONE I do, truly; for thou swearest to me thou art + honest: now, if thou wert a poet, I might have some + hope thou didst feign. + +AUDREY Would you not have me honest? + +TOUCHSTONE No, truly, unless thou wert hard-favoured; for + honesty coupled to beauty is to have honey a sauce to sugar. + +JAQUES [Aside] A material fool! + +AUDREY Well, I am not fair; and therefore I pray the gods + make me honest. + +TOUCHSTONE Truly, and to cast away honesty upon a foul slut + were to put good meat into an unclean dish. + +AUDREY I am not a slut, though I thank the gods I am foul. + +TOUCHSTONE Well, praised be the gods for thy foulness! + sluttishness may come hereafter. But be it as it may + be, I will marry thee, and to that end I have been + with Sir Oliver Martext, the vicar of the next + village, who hath promised to meet me in this place + of the forest and to couple us. + +JAQUES [Aside] I would fain see this meeting. + +AUDREY Well, the gods give us joy! + +TOUCHSTONE Amen. A man may, if he were of a fearful heart, + stagger in this attempt; for here we have no temple + but the wood, no assembly but horn-beasts. But what + though? Courage! As horns are odious, they are + necessary. It is said, 'many a man knows no end of + his goods:' right; many a man has good horns, and + knows no end of them. Well, that is the dowry of + his wife; 'tis none of his own getting. Horns? + Even so. Poor men alone? No, no; the noblest deer + hath them as huge as the rascal. Is the single man + therefore blessed? No: as a walled town is more + worthier than a village, so is the forehead of a + married man more honourable than the bare brow of a + bachelor; and by how much defence is better than no + skill, by so much is a horn more precious than to + want. Here comes Sir Oliver. + + [Enter SIR OLIVER MARTEXT] + + Sir Oliver Martext, you are well met: will you + dispatch us here under this tree, or shall we go + with you to your chapel? + +SIR OLIVER MARTEXT Is there none here to give the woman? + +TOUCHSTONE I will not take her on gift of any man. + +SIR OLIVER MARTEXT Truly, she must be given, or the marriage is not lawful. + +JAQUES [Advancing] + + Proceed, proceed I'll give her. + +TOUCHSTONE Good even, good Master What-ye-call't: how do you, + sir? You are very well met: God 'ild you for your + last company: I am very glad to see you: even a + toy in hand here, sir: nay, pray be covered. + +JAQUES Will you be married, motley? + +TOUCHSTONE As the ox hath his bow, sir, the horse his curb and + the falcon her bells, so man hath his desires; and + as pigeons bill, so wedlock would be nibbling. + +JAQUES And will you, being a man of your breeding, be + married under a bush like a beggar? Get you to + church, and have a good priest that can tell you + what marriage is: this fellow will but join you + together as they join wainscot; then one of you will + prove a shrunk panel and, like green timber, warp, warp. + +TOUCHSTONE [Aside] I am not in the mind but I were better to be + married of him than of another: for he is not like + to marry me well; and not being well married, it + will be a good excuse for me hereafter to leave my wife. + +JAQUES Go thou with me, and let me counsel thee. + +TOUCHSTONE 'Come, sweet Audrey: + We must be married, or we must live in bawdry. + Farewell, good Master Oliver: not,-- + O sweet Oliver, + O brave Oliver, + Leave me not behind thee: but,-- + Wind away, + Begone, I say, + I will not to wedding with thee. + + [Exeunt JAQUES, TOUCHSTONE and AUDREY] + +SIR OLIVER MARTEXT 'Tis no matter: ne'er a fantastical knave of them + all shall flout me out of my calling. + + [Exit] + + + + + AS YOU LIKE IT + + +ACT III + + + +SCENE IV The forest. + + + [Enter ROSALIND and CELIA] + +ROSALIND Never talk to me; I will weep. + +CELIA Do, I prithee; but yet have the grace to consider + that tears do not become a man. + +ROSALIND But have I not cause to weep? + +CELIA As good cause as one would desire; therefore weep. + +ROSALIND His very hair is of the dissembling colour. + +CELIA Something browner than Judas's marry, his kisses are + Judas's own children. + +ROSALIND I' faith, his hair is of a good colour. + +CELIA An excellent colour: your chestnut was ever the only colour. + +ROSALIND And his kissing is as full of sanctity as the touch + of holy bread. + +CELIA He hath bought a pair of cast lips of Diana: a nun + of winter's sisterhood kisses not more religiously; + the very ice of chastity is in them. + +ROSALIND But why did he swear he would come this morning, and + comes not? + +CELIA Nay, certainly, there is no truth in him. + +ROSALIND Do you think so? + +CELIA Yes; I think he is not a pick-purse nor a + horse-stealer, but for his verity in love, I do + think him as concave as a covered goblet or a + worm-eaten nut. + +ROSALIND Not true in love? + +CELIA Yes, when he is in; but I think he is not in. + +ROSALIND You have heard him swear downright he was. + +CELIA 'Was' is not 'is:' besides, the oath of a lover is + no stronger than the word of a tapster; they are + both the confirmer of false reckonings. He attends + here in the forest on the duke your father. + +ROSALIND I met the duke yesterday and had much question with + him: he asked me of what parentage I was; I told + him, of as good as he; so he laughed and let me go. + But what talk we of fathers, when there is such a + man as Orlando? + +CELIA O, that's a brave man! he writes brave verses, + speaks brave words, swears brave oaths and breaks + them bravely, quite traverse, athwart the heart of + his lover; as a puisny tilter, that spurs his horse + but on one side, breaks his staff like a noble + goose: but all's brave that youth mounts and folly + guides. Who comes here? + + [Enter CORIN] + +CORIN Mistress and master, you have oft inquired + After the shepherd that complain'd of love, + Who you saw sitting by me on the turf, + Praising the proud disdainful shepherdess + That was his mistress. + +CELIA Well, and what of him? + +CORIN If you will see a pageant truly play'd, + Between the pale complexion of true love + And the red glow of scorn and proud disdain, + Go hence a little and I shall conduct you, + If you will mark it. + +ROSALIND O, come, let us remove: + The sight of lovers feedeth those in love. + Bring us to this sight, and you shall say + I'll prove a busy actor in their play. + + [Exeunt] + + + + + AS YOU LIKE IT + + +ACT III + + + +SCENE V Another part of the forest. + + + [Enter SILVIUS and PHEBE] + +SILVIUS Sweet Phebe, do not scorn me; do not, Phebe; + Say that you love me not, but say not so + In bitterness. The common executioner, + Whose heart the accustom'd sight of death makes hard, + Falls not the axe upon the humbled neck + But first begs pardon: will you sterner be + Than he that dies and lives by bloody drops? + + [Enter ROSALIND, CELIA, and CORIN, behind] + +PHEBE I would not be thy executioner: + I fly thee, for I would not injure thee. + Thou tell'st me there is murder in mine eye: + 'Tis pretty, sure, and very probable, + That eyes, that are the frail'st and softest things, + Who shut their coward gates on atomies, + Should be call'd tyrants, butchers, murderers! + Now I do frown on thee with all my heart; + And if mine eyes can wound, now let them kill thee: + Now counterfeit to swoon; why now fall down; + Or if thou canst not, O, for shame, for shame, + Lie not, to say mine eyes are murderers! + Now show the wound mine eye hath made in thee: + Scratch thee but with a pin, and there remains + Some scar of it; lean but upon a rush, + The cicatrice and capable impressure + Thy palm some moment keeps; but now mine eyes, + Which I have darted at thee, hurt thee not, + Nor, I am sure, there is no force in eyes + That can do hurt. + +SILVIUS O dear Phebe, + If ever,--as that ever may be near,-- + You meet in some fresh cheek the power of fancy, + Then shall you know the wounds invisible + That love's keen arrows make. + +PHEBE But till that time + Come not thou near me: and when that time comes, + Afflict me with thy mocks, pity me not; + As till that time I shall not pity thee. + +ROSALIND And why, I pray you? Who might be your mother, + That you insult, exult, and all at once, + Over the wretched? What though you have no beauty,-- + As, by my faith, I see no more in you + Than without candle may go dark to bed-- + Must you be therefore proud and pitiless? + Why, what means this? Why do you look on me? + I see no more in you than in the ordinary + Of nature's sale-work. 'Od's my little life, + I think she means to tangle my eyes too! + No, faith, proud mistress, hope not after it: + 'Tis not your inky brows, your black silk hair, + Your bugle eyeballs, nor your cheek of cream, + That can entame my spirits to your worship. + You foolish shepherd, wherefore do you follow her, + Like foggy south puffing with wind and rain? + You are a thousand times a properer man + Than she a woman: 'tis such fools as you + That makes the world full of ill-favour'd children: + 'Tis not her glass, but you, that flatters her; + And out of you she sees herself more proper + Than any of her lineaments can show her. + But, mistress, know yourself: down on your knees, + And thank heaven, fasting, for a good man's love: + For I must tell you friendly in your ear, + Sell when you can: you are not for all markets: + Cry the man mercy; love him; take his offer: + Foul is most foul, being foul to be a scoffer. + So take her to thee, shepherd: fare you well. + +PHEBE Sweet youth, I pray you, chide a year together: + I had rather hear you chide than this man woo. + +ROSALIND He's fallen in love with your foulness and she'll + fall in love with my anger.

By my faith, you have great reason to + be sad: I fear you have sold your own lands to see + other men's; then, to have seen much and to have + nothing, is to have rich eyes and poor hands. + +JAQUES Yes, I have gained my experience. + +ROSALIND And your experience makes you sad: I had rather have + a fool to make me merry than experience to make me + sad; and to travel for it too! + + [Enter ORLANDO] + +ORLANDO Good day and happiness, dear Rosalind! + +JAQUES Nay, then, God be wi' you, an you talk in blank verse. + + [Exit] + +ROSALIND Farewell, Monsieur Traveller: look you lisp and + wear strange suits, disable all the benefits of your + own country, be out of love with your nativity and + almost chide God for making you that countenance you + are, or I will scarce think you have swam in a + gondola. Why, how now, Orlando! where have you been + all this while? You a lover! An you serve me such + another trick, never come in my sight more. + +ORLANDO My fair Rosalind, I come within an hour of my promise. + +ROSALIND Break an hour's promise in love! He that will + divide a minute into a thousand parts and break but + a part of the thousandth part of a minute in the + affairs of love, it may be said of him that Cupid + hath clapped him o' the shoulder, but I'll warrant + him heart-whole. + +ORLANDO Pardon me, dear Rosalind. + +ROSALIND Nay, an you be so tardy, come no more in my sight: I + had as lief be wooed of a snail. + +ORLANDO Of a snail? + +ROSALIND Ay, of a snail; for though he comes slowly, he + carries his house on his head; a better jointure, + I think, than you make a woman: besides he brings + his destiny with him. + +ORLANDO What's that? + +ROSALIND Why, horns, which such as you are fain to be + beholding to your wives for: but he comes armed in + his fortune and prevents the slander of his wife. + +ORLANDO Virtue is no horn-maker; and my Rosalind is virtuous. + +ROSALIND And I am your Rosalind. + +CELIA It pleases him to call you so; but he hath a + Rosalind of a better leer than you. + +ROSALIND Come, woo me, woo me, for now I am in a holiday + humour and like enough to consent. What would you + say to me now, an I were your very very Rosalind? + +ORLANDO I would kiss before I spoke. + +ROSALIND Nay, you were better speak first, and when you were + gravelled for lack of matter, you might take + occasion to kiss. Very good orators, when they are + out, they will spit; and for lovers lacking--God + warn us!--matter, the cleanliest shift is to kiss. + +ORLANDO How if the kiss be denied? + +ROSALIND Then she puts you to entreaty, and there begins new matter. + +ORLANDO Who could be out, being before his beloved mistress? + +ROSALIND Marry, that should you, if I were your mistress, or + I should think my honesty ranker than my wit. + +ORLANDO What, of my suit? + +ROSALIND Not out of your apparel, and yet out of your suit. + Am not I your Rosalind? + +ORLANDO I take some joy to say you are, because I would be + talking of her. + +ROSALIND Well in her person I say I will not have you. + +ORLANDO Then in mine own person I die. + +ROSALIND No, faith, die by attorney. The poor world is + almost six thousand years old, and in all this time + there was not any man died in his own person, + videlicit, in a love-cause. Troilus had his brains + dashed out with a Grecian club; yet he did what he + could to die before, and he is one of the patterns + of love. Leander, he would have lived many a fair + year, though Hero had turned nun, if it had not been + for a hot midsummer night; for, good youth, he went + but forth to wash him in the Hellespont and being + taken with the cramp was drowned and the foolish + coroners of that age found it was 'Hero of Sestos.' + But these are all lies: men have died from time to + time and worms have eaten them, but not for love. + +ORLANDO I would not have my right Rosalind of this mind, + for, I protest, her frown might kill me. + +ROSALIND By this hand, it will not kill a fly. But come, now + I will be your Rosalind in a more coming-on + disposition, and ask me what you will. I will grant + it. + +ORLANDO Then love me, Rosalind. + +ROSALIND Yes, faith, will I, Fridays and Saturdays and all. + +ORLANDO And wilt thou have me? + +ROSALIND Ay, and twenty such. + +ORLANDO What sayest thou? + +ROSALIND Are you not good? + +ORLANDO I hope so. + +ROSALIND Why then, can one desire too much of a good thing? + Come, sister, you shall be the priest and marry us. + Give me your hand, Orlando. What do you say, sister? + +ORLANDO Pray thee, marry us. + +CELIA I cannot say the words. + +ROSALIND You must begin, 'Will you, Orlando--' + +CELIA Go to. Will you, Orlando, have to wife this Rosalind? + +ORLANDO I will. + +ROSALIND Ay, but when? + +ORLANDO Why now; as fast as she can marry us. + +ROSALIND Then you must say 'I take thee, Rosalind, for wife.' + +ORLANDO I take thee, Rosalind, for wife. + +ROSALIND I might ask you for your commission; but I do take + thee, Orlando, for my husband: there's a girl goes + before the priest; and certainly a woman's thought + runs before her actions. + +ORLANDO So do all thoughts; they are winged. + +ROSALIND Now tell me how long you would have her after you + have possessed her. + +ORLANDO For ever and a day. + +ROSALIND Say 'a day,' without the 'ever.' No, no, Orlando; + men are April when they woo, December when they wed: + maids are May when they are maids, but the sky + changes when they are wives. I will be more jealous + of thee than a Barbary cock-pigeon over his hen, + more clamorous than a parrot against rain, more + new-fangled than an ape, more giddy in my desires + than a monkey: I will weep for nothing, like Diana + in the fountain, and I will do that when you are + disposed to be merry; I will laugh like a hyen, and + that when thou art inclined to sleep. + +ORLANDO But will my Rosalind do so? + +ROSALIND By my life, she will do as I do. + +ORLANDO O, but she is wise. + +ROSALIND Or else she could not have the wit to do this: the + wiser, the waywarder: make the doors upon a woman's + wit and it will out at the casement; shut that and + 'twill out at the key-hole; stop that, 'twill fly + with the smoke out at the chimney. + +ORLANDO A man that had a wife with such a wit, he might say + 'Wit, whither wilt?' + +ROSALIND Nay, you might keep that cheque for it till you met + your wife's wit going to your neighbour's bed. + +ORLANDO And what wit could wit have to excuse that? + +ROSALIND Marry, to say she came to seek you there. You shall + never take her without her answer, unless you take + her without her tongue.

But + it cannot be sounded: my affection hath an unknown + bottom, like the bay of Portugal. + +CELIA Or rather, bottomless, that as fast as you pour + affection in, it runs out. + +ROSALIND No, that same wicked bastard of Venus that was begot + of thought, conceived of spleen and born of madness, + that blind rascally boy that abuses every one's eyes + because his own are out, let him be judge how deep I + am in love. I'll tell thee, Aliena, I cannot be out + of the sight of Orlando: I'll go find a shadow and + sigh till he come. + +CELIA And I'll sleep. + + [Exeunt] + + + + + AS YOU LIKE IT + + +ACT IV + + + +SCENE II The forest. + + + [Enter JAQUES, Lords, and Foresters] + +JAQUES Which is he that killed the deer? + +A Lord Sir, it was I. + +JAQUES Let's present him to the duke, like a Roman + conqueror; and it would do well to set the deer's + horns upon his head, for a branch of victory.

'Od's my will! + Her love is not the hare that I do hunt: + Why writes she so to me? Well, shepherd, well, + This is a letter of your own device. + +SILVIUS No, I protest, I know not the contents: + Phebe did write it. + +ROSALIND Come, come, you are a fool + And turn'd into the extremity of love. + I saw her hand: she has a leathern hand. + A freestone-colour'd hand; I verily did think + That her old gloves were on, but 'twas her hands: + She has a huswife's hand; but that's no matter: + I say she never did invent this letter; + This is a man's invention and his hand. + +SILVIUS Sure, it is hers. + +ROSALIND Why, 'tis a boisterous and a cruel style. + A style for-challengers; why, she defies me, + Like Turk to Christian: women's gentle brain + Could not drop forth such giant-rude invention + Such Ethiope words, blacker in their effect + Than in their countenance. Will you hear the letter? + +SILVIUS So please you, for I never heard it yet; + Yet heard too much of Phebe's cruelty. + +ROSALIND She Phebes me: mark how the tyrant writes. + + [Reads] + + Art thou god to shepherd turn'd, + That a maiden's heart hath burn'd? + Can a woman rail thus? + +SILVIUS Call you this railing? + +ROSALIND [Reads] + + Why, thy godhead laid apart, + Warr'st thou with a woman's heart? + Did you ever hear such railing? + Whiles the eye of man did woo me, + That could do no vengeance to me. + Meaning me a beast. + If the scorn of your bright eyne + Have power to raise such love in mine, + Alack, in me what strange effect + Would they work in mild aspect! + Whiles you chid me, I did love; + How then might your prayers move! + He that brings this love to thee + Little knows this love in me: + And by him seal up thy mind; + Whether that thy youth and kind + Will the faithful offer take + Of me and all that I can make; + Or else by him my love deny, + And then I'll study how to die. + +SILVIUS Call you this chiding? + +CELIA Alas, poor shepherd! + +ROSALIND Do you pity him? no, he deserves no pity.

Ah, sirrah, a body would + think this was well counterfeited! I pray you, tell + your brother how well I counterfeited.

Art thou wise? + +WILLIAM Ay, sir, I have a pretty wit. + +TOUCHSTONE Why, thou sayest well. I do now remember a saying, + 'The fool doth think he is wise, but the wise man + knows himself to be a fool.' The heathen + philosopher, when he had a desire to eat a grape, + would open his lips when he put it into his mouth; + meaning thereby that grapes were made to eat and + lips to open. You do love this maid? + +WILLIAM I do, sir. + +TOUCHSTONE Give me your hand. Art thou learned? + +WILLIAM No, sir. + +TOUCHSTONE Then learn this of me: to have, is to have; for it + is a figure in rhetoric that drink, being poured out + of a cup into a glass, by filling the one doth empty + the other; for all your writers do consent that ipse + is he: now, you are not ipse, for I am he. + +WILLIAM Which he, sir? + +TOUCHSTONE He, sir, that must marry this woman.

Believe then, if + you please, that I can do strange things: I have, + since I was three year old, conversed with a + magician, most profound in his art and yet not + damnable. If you do love Rosalind so near the heart + as your gesture cries it out, when your brother + marries Aliena, shall you marry her: I know into + what straits of fortune she is driven; and it is + not impossible to me, if it appear not inconvenient + to you, to set her before your eyes tomorrow human + as she is and without any danger. + +ORLANDO Speakest thou in sober meanings? + +ROSALIND By my life, I do; which I tender dearly, though I + say I am a magician.

I have trod a measure; I have flattered + a lady; I have been politic with my friend, smooth + with mine enemy; I have undone three tailors; I have + had four quarrels, and like to have fought one. + +JAQUES And how was that ta'en up? + +TOUCHSTONE Faith, we met, and found the quarrel was upon the + seventh cause. + +JAQUES How seventh cause? Good my lord, like this fellow. + +DUKE SENIOR I like him very well. + +TOUCHSTONE God 'ild you, sir; I desire you of the like. I + press in here, sir, amongst the rest of the country + copulatives, to swear and to forswear: according as + marriage binds and blood breaks: a poor virgin, + sir, an ill-favoured thing, sir, but mine own; a poor + humour of mine, sir, to take that that no man else + will: rich honesty dwells like a miser, sir, in a + poor house; as your pearl in your foul oyster. + +DUKE SENIOR By my faith, he is very swift and sententious. + +TOUCHSTONE According to the fool's bolt, sir, and such dulcet diseases. + +JAQUES But, for the seventh cause; how did you find the + quarrel on the seventh cause? + +TOUCHSTONE Upon a lie seven times removed:--bear your body more + seeming, Audrey:--as thus, sir. I did dislike the + cut of a certain courtier's beard: he sent me word, + if I said his beard was not cut well, he was in the + mind it was: this is called the Retort Courteous. + If I sent him word again 'it was not well cut,' he + would send me word, he cut it to please himself: + this is called the Quip Modest. If again 'it was + not well cut,' he disabled my judgment: this is + called the Reply Churlish. If again 'it was not + well cut,' he would answer, I spake not true: this + is called the Reproof Valiant. If again 'it was not + well cut,' he would say I lied: this is called the + Counter-cheque Quarrelsome: and so to the Lie + Circumstantial and the Lie Direct. + +JAQUES And how oft did you say his beard was not well cut? + +TOUCHSTONE I durst go no further than the Lie Circumstantial, + nor he durst not give me the Lie Direct; and so we + measured swords and parted. + +JAQUES Can you nominate in order now the degrees of the lie? + +TOUCHSTONE O sir, we quarrel in print, by the book; as you have + books for good manners: I will name you the degrees. + The first, the Retort Courteous; the second, the + Quip Modest; the third, the Reply Churlish; the + fourth, the Reproof Valiant; the fifth, the + Countercheque Quarrelsome; the sixth, the Lie with + Circumstance; the seventh, the Lie Direct. All + these you may avoid but the Lie Direct; and you may + avoid that too, with an If. I knew when seven + justices could not take up a quarrel, but when the + parties were met themselves, one of them thought but + of an If, as, 'If you said so, then I said so;' and + they shook hands and swore brothers.

This to be true, + I do engage my life. + +DUKE SENIOR Welcome, young man; + Thou offer'st fairly to thy brothers' wedding: + To one his lands withheld, and to the other + A land itself at large, a potent dukedom. + First, in this forest, let us do those ends + That here were well begun and well begot: + And after, every of this happy number + That have endured shrewd days and nights with us + Shall share the good of our returned fortune, + According to the measure of their states. + Meantime, forget this new-fall'n dignity + And fall into our rustic revelry. + Play, music! And you, brides and bridegrooms all, + With measure heap'd in joy, to the measures fall. + +JAQUES Sir, by your patience. If I heard you rightly, + The duke hath put on a religious life + And thrown into neglect the pompous court? + +JAQUES DE BOYS He hath. + +JAQUES To him will I : out of these convertites + There is much matter to be heard and learn'd. + + [To DUKE SENIOR] + + You to your former honour I bequeath; + Your patience and your virtue well deserves it: + + [To ORLANDO] + + You to a love that your true faith doth merit: + + [To OLIVER] + + You to your land and love and great allies: + + [To SILVIUS] + + You to a long and well-deserved bed: + + [To TOUCHSTONE] + + And you to wrangling; for thy loving voyage + Is but for two months victuall'd.

If it be true that good wine needs + no bush, 'tis true that a good play needs no + epilogue; yet to good wine they do use good bushes, + and good plays prove the better by the help of good + epilogues. What a case am I in then, that am + neither a good epilogue nor cannot insinuate with + you in the behalf of a good play! I am not + furnished like a beggar, therefore to beg will not + become me: my way is to conjure you; and I'll begin + with the women.

Most attendees gained +much in insight and outlook from the event. But the assembly did not +form a new nation, or, to put it another way, the diversity of projects +and interests was too great to draw the representatives into a cohesive, +action-oriented body.(2) + +Everyone attending the Workshop shared an interest in preserving and +providing access to historical texts. But within this broad field the +attendees represented a variety of formal, informal, figurative, and +literal groups, with many individuals belonging to more than one. These +groups may be defined roughly according to the following topics or +activities: + +* Imaging +* Searchable coded texts +* National and international computer networks +* CD-ROM production and dissemination +* Methods and technology for converting older paper materials into +electronic form +* Study of the use of digital materials by scholars and others + +This summary is arranged thematically and does not follow the actual +sequence of presentations. + +NOTES: + (1) In this document, the phrase electronic text is used to mean + any computerized reproduction or version of a document, book, + article, or manuscript (including images), and not merely a machine- + readable or machine-searchable text. + + (2) The Workshop was held at the Library of Congress on 9-10 June + 1992, with funding from the David and Lucile Packard Foundation. + The document that follows represents a summary of the presentations + made at the Workshop and was compiled by James DALY. This + introduction was written by DALY and Carl FLEISCHHAUER. + + +PRESERVATION AND IMAGING + +Preservation, as that term is used by archivists,(3) was most explicitly +discussed in the context of imaging. Anne KENNEY and Lynne PERSONIUS +explained how the concept of a faithful copy and the user-friendliness of +the traditional book have guided their project at Cornell University.(4) +Although interested in computerized dissemination, participants in the +Cornell project are creating digital image sets of older books in the +public domain as a source for a fresh paper facsimile or, in a future +phase, microfilm. The books returned to the library shelves are +high-quality and useful replacements on acid-free paper that should last +a long time. To date, the Cornell project has placed little or no +emphasis on creating searchable texts; one would not be surprised to find +that the project participants view such texts as new editions, and thus +not as faithful reproductions. + +In her talk on preservation, Patricia BATTIN struck an ecumenical and +flexible note as she endorsed the creation and dissemination of a variety +of types of digital copies. Do not be too narrow in defining what counts +as a preservation element, BATTIN counseled; for the present, at least, +digital copies made with preservation in mind cannot be as narrowly +standardized as, say, microfilm copies with the same objective. Setting +standards precipitously can inhibit creativity, but delay can result in +chaos, she advised. + +In part, BATTIN's position reflected the unsettled nature of image-format +standards, and attendees could hear echoes of this unsettledness in the +comments of various speakers. For example, Jean BARONAS reviewed the +status of several formal standards moving through committees of experts; +and Clifford LYNCH encouraged the use of a new guideline for transmitting +document images on Internet. Testimony from participants in the National +Agricultural Library's (NAL) Text Digitization Program and LC's American +Memory project highlighted some of the challenges to the actual creation +or interchange of images, including difficulties in converting +preservation microfilm to digital form. Donald WATERS reported on the +progress of a master plan for a project at Yale University to convert +books on microfilm to digital image sets, Project Open Book (POB). + +The Workshop offered rather less of an imaging practicum than planned, +but "how-to" hints emerge at various points, for example, throughout +KENNEY's presentation and in the discussion of arcana such as +thresholding and dithering offered by George THOMA and FLEISCHHAUER. + +NOTES: + (3) Although there is a sense in which any reproductions of + historical materials preserve the human record, specialists in the + field have developed particular guidelines for the creation of + acceptable preservation copies. + + (4) Titles and affiliations of presenters are given at the + beginning of their respective talks and in the Directory of + Participants (Appendix III). + + +THE MACHINE-READABLE TEXT: MARKUP AND USE + +The sections of the Workshop that dealt with machine-readable text tended +to be more concerned with access and use than with preservation, at least +in the narrow technical sense. Michael SPERBERG-McQUEEN made a forceful +presentation on the Text Encoding Initiative's (TEI) implementation of +the Standard Generalized Markup Language (SGML). His ideas were echoed +by Susan HOCKEY, Elli MYLONAS, and Stuart WEIBEL. While the +presentations made by the TEI advocates contained no practicum, their +discussion focused on the value of the finished product, what the +European Community calls reusability, but what may also be termed +durability. They argued that marking up--that is, coding--a text in a +well-conceived way will permit it to be moved from one computer +environment to another, as well as to be used by various users. Two +kinds of markup were distinguished: 1) procedural markup, which +describes the features of a text (e.g., dots on a page), and 2) +descriptive markup, which describes the structure or elements of a +document (e.g., chapters, paragraphs, and front matter). + +The TEI proponents emphasized the importance of texts to scholarship. +They explained how heavily coded (and thus analyzed and annotated) texts +can underlie research, play a role in scholarly communication, and +facilitate classroom teaching. SPERBERG-McQUEEN reminded listeners that +a written or printed item (e.g., a particular edition of a book) is +merely a representation of the abstraction we call a text. To concern +ourselves with faithfully reproducing a printed instance of the text, +SPERBERG-McQUEEN argued, is to concern ourselves with the representation +of a representation ("images as simulacra for the text"). The TEI proponents' +interest in images tends to focus on corollary materials for use in teaching, +for example, photographs of the Acropolis to accompany a Greek text. + +By the end of the Workshop, SPERBERG-McQUEEN confessed to having been +converted to a limited extent to the view that electronic images +constitute a promising alternative to microfilming; indeed, an +alternative probably superior to microfilming. But he was not convinced +that electronic images constitute a serious attempt to represent text in +electronic form. HOCKEY and MYLONAS also conceded that their experience +at the Pierce Symposium the previous week at Georgetown University and +the present conference at the Library of Congress had compelled them to +reevaluate their perspective on the usefulness of text as images. +Attendees could see that the text and image advocates were in +constructive tension, so to say. + +Three nonTEI presentations described approaches to preparing +machine-readable text that are less rigorous and thus less expensive. In +the case of the Papers of George Washington, Dorothy TWOHIG explained +that the digital version will provide a not-quite-perfect rendering of +the transcribed text--some 135,000 documents, available for research +during the decades while the perfect or print version is completed. +Members of the American Memory team and the staff of NAL's Text +Digitization Program (see below) also outlined a middle ground concerning +searchable texts. In the case of American Memory, contractors produce +texts with about 99-percent accuracy that serve as "browse" or +"reference" versions of written or printed originals. End users who need +faithful copies or perfect renditions must refer to accompanying sets of +digital facsimile images or consult copies of the originals in a nearby +library or archive. American Memory staff argued that the high cost of +producing 100-percent accurate copies would prevent LC from offering +access to large parts of its collections. + + +THE MACHINE-READABLE TEXT: METHODS OF CONVERSION + +Although the Workshop did not include a systematic examination of the +methods for converting texts from paper (or from facsimile images) into +machine-readable form, nevertheless, various speakers touched upon this +matter. For example, WEIBEL reported that OCLC has experimented with a +merging of multiple optical character recognition systems that will +reduce errors from an unacceptable rate of 5 characters out of every +l,000 to an unacceptable rate of 2 characters out of every l,000. + +Pamela ANDRE presented an overview of NAL's Text Digitization Program and +Judith ZIDAR discussed the technical details. ZIDAR explained how NAL +purchased hardware and software capable of performing optical character +recognition (OCR) and text conversion and used its own staff to convert +texts. The process, ZIDAR said, required extensive editing and project +staff found themselves considering alternatives, including rekeying +and/or creating abstracts or summaries of texts. NAL reckoned costs at +$7 per page. By way of contrast, Ricky ERWAY explained that American +Memory had decided from the start to contract out conversion to external +service bureaus. The criteria used to select these contractors were cost +and quality of results, as opposed to methods of conversion. ERWAY noted +that historical documents or books often do not lend themselves to OCR. +Bound materials represent a special problem. In her experience, quality +control--inspecting incoming materials, counting errors in samples--posed +the most time-consuming aspect of contracting out conversion. ERWAY +reckoned American Memory's costs at $4 per page, but cautioned that fewer +cost-elements had been included than in NAL's figure. + + +OPTIONS FOR DISSEMINATION + +The topic of dissemination proper emerged at various points during the +Workshop. At the session devoted to national and international computer +networks, LYNCH, Howard BESSER, Ronald LARSEN, and Edwin BROWNRIGG +highlighted the virtues of Internet today and of the network that will +evolve from Internet. Listeners could discern in these narratives a +vision of an information democracy in which millions of citizens freely +find and use what they need. LYNCH noted that a lack of standards +inhibits disseminating multimedia on the network, a topic also discussed +by BESSER. LARSEN addressed the issues of network scalability and +modularity and commented upon the difficulty of anticipating the effects +of growth in orders of magnitude. BROWNRIGG talked about the ability of +packet radio to provide certain links in a network without the need for +wiring. However, the presenters also called attention to the +shortcomings and incongruities of present-day computer networks. For +example: 1) Network use is growing dramatically, but much network +traffic consists of personal communication (E-mail). 2) Large bodies of +information are available, but a user's ability to search across their +entirety is limited. 3) There are significant resources for science and +technology, but few network sources provide content in the humanities. +4) Machine-readable texts are commonplace, but the capability of the +system to deal with images (let alone other media formats) lags behind. +A glimpse of a multimedia future for networks, however, was provided by +Maria LEBRON in her overview of the Online Journal of Current Clinical +Trials (OJCCT), and the process of scholarly publishing on-line. + +The contrasting form of the CD-ROM disk was never systematically +analyzed, but attendees could glean an impression from several of the +show-and-tell presentations. The Perseus and American Memory examples +demonstrated recently published disks, while the descriptions of the +IBYCUS version of the Papers of George Washington and Chadwyck-Healey's +Patrologia Latina Database (PLD) told of disks to come. According to +Eric CALALUCA, PLD's principal focus has been on converting Jacques-Paul +Migne's definitive collection of Latin texts to machine-readable form. +Although everyone could share the network advocates' enthusiasm for an +on-line future, the possibility of rolling up one's sleeves for a session +with a CD-ROM containing both textual materials and a powerful retrieval +engine made the disk seem an appealing vessel indeed. The overall +discussion suggested that the transition from CD-ROM to on-line networked +access may prove far slower and more difficult than has been anticipated. + + +WHO ARE THE USERS AND WHAT DO THEY DO? + +Although concerned with the technicalities of production, the Workshop +never lost sight of the purposes and uses of electronic versions of +textual materials. As noted above, those interested in imaging discussed +the problematical matter of digital preservation, while the TEI proponents +described how machine-readable texts can be used in research. This latter +topic received thorough treatment in the paper read by Avra MICHELSON. +She placed the phenomenon of electronic texts within the context of +broader trends in information technology and scholarly communication. + +Among other things, MICHELSON described on-line conferences that +represent a vigorous and important intellectual forum for certain +disciplines. Internet now carries more than 700 conferences, with about +80 percent of these devoted to topics in the social sciences and the +humanities. Other scholars use on-line networks for "distance learning." +Meanwhile, there has been a tremendous growth in end-user computing; +professors today are less likely than their predecessors to ask the +campus computer center to process their data. Electronic texts are one +key to these sophisticated applications, MICHELSON reported, and more and +more scholars in the humanities now work in an on-line environment. +Toward the end of the Workshop, Michael LESK presented a corollary to +MICHELSON's talk, reporting the results of an experiment that compared +the work of one group of chemistry students using traditional printed +texts and two groups using electronic sources. The experiment +demonstrated that in the event one does not know what to read, one needs +the electronic systems; the electronic systems hold no advantage at the +moment if one knows what to read, but neither do they impose a penalty. + +DALY provided an anecdotal account of the revolutionizing impact of the +new technology on his previous methods of research in the field of classics. +His account, by extrapolation, served to illustrate in part the arguments +made by MICHELSON concerning the positive effects of the sudden and radical +transformation being wrought in the ways scholars work. + +Susan VECCIA and Joanne FREEMAN delineated the use of electronic +materials outside the university. The most interesting aspect of their +use, FREEMAN said, could be seen as a paradox: teachers in elementary +and secondary schools requested access to primary source materials but, +at the same time, found that "primariness" itself made these materials +difficult for their students to use. + + +OTHER TOPICS + +Marybeth PETERS reviewed copyright law in the United States and offered +advice during a lively discussion of this subject. But uncertainty +remains concerning the price of copyright in a digital medium, because a +solution remains to be worked out concerning management and synthesis of +copyrighted and out-of-copyright pieces of a database. + +As moderator of the final session of the Workshop, Prosser GIFFORD directed +discussion to future courses of action and the potential role of LC in +advancing them. Among the recommendations that emerged were the following: + + * Workshop participants should 1) begin to think about working + with image material, but structure and digitize it in such a + way that at a later stage it can be interpreted into text, and + 2) find a common way to build text and images together so that + they can be used jointly at some stage in the future, with + appropriate network support, because that is how users will want + to access these materials. The Library might encourage attempts + to bring together people who are working on texts and images. + + * A network version of American Memory should be developed or + consideration should be given to making the data in it + available to people interested in doing network multimedia. + Given the current dearth of digital data that is appealing and + unencumbered by extremely complex rights problems, developing a + network version of American Memory could do much to help make + network multimedia a reality. + + * Concerning the thorny issue of electronic deposit, LC should + initiate a catalytic process in terms of distributed + responsibility, that is, bring together the distributed + organizations and set up a study group to look at all the + issues related to electronic deposit and see where we as a + nation should move. For example, LC might attempt to persuade + one major library in each state to deal with its state + equivalent publisher, which might produce a cooperative project + that would be equitably distributed around the country, and one + in which LC would be dealing with a minimal number of publishers + and minimal copyright problems. LC must also deal with the + concept of on-line publishing, determining, among other things, + how serials such as OJCCT might be deposited for copyright. + + * Since a number of projects are planning to carry out + preservation by creating digital images that will end up in + on-line or near-line storage at some institution, LC might play + a helpful role, at least in the near term, by accelerating how + to catalog that information into the Research Library Information + Network (RLIN) and then into OCLC, so that it would be accessible. + This would reduce the possibility of multiple institutions digitizing + the same work. + + +CONCLUSION + +The Workshop was valuable because it brought together partisans from +various groups and provided an occasion to compare goals and methods. +The more committed partisans frequently communicate with others in their +groups, but less often across group boundaries. The Workshop was also +valuable to attendees--including those involved with American Memory--who +came less committed to particular approaches or concepts. These +attendees learned a great deal, and plan to select and employ elements of +imaging, text-coding, and networked distribution that suit their +respective projects and purposes. + +Still, reality rears its ugly head: no breakthrough has been achieved. +On the imaging side, one confronts a proliferation of competing +data-interchange standards and a lack of consensus on the role of digital +facsimiles in preservation. In the realm of machine-readable texts, one +encounters a reasonably mature standard but methodological difficulties +and high costs. These latter problems, of course, represent a special +impediment to the desire, as it is sometimes expressed in the popular +press, "to put the [contents of the] Library of Congress on line." In +the words of one participant, there was "no solution to the economic +problems--the projects that are out there are surviving, but it is going +to be a lot of work to transform the information industry, and so far the +investment to do that is not forthcoming" (LESK, per litteras). + + + *** *** *** ****** *** *** *** + + + PROCEEDINGS + + +WELCOME + ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ +GIFFORD * Origin of Workshop in current Librarian's desire to make LC's +collections more widely available * Desiderata arising from the prospect +of greater interconnectedness * ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ + +After welcoming participants on behalf of the Library of Congress, +American Memory (AM), and the National Demonstration Lab, Prosser +GIFFORD, director for scholarly programs, Library of Congress, located +the origin of the Workshop on Electronic Texts in a conversation he had +had considerably more than a year ago with Carl FLEISCHHAUER concerning +some of the issues faced by AM. On the assumption that numerous other +people were asking the same questions, the decision was made to bring +together as many of these people as possible to ask the same questions +together. In a deeper sense, GIFFORD said, the origin of the Workshop +lay in the desire of the current Librarian of Congress, James H. +Billington, to make the collections of the Library, especially those +offering unique or unusual testimony on aspects of the American +experience, available to a much wider circle of users than those few +people who can come to Washington to use them. This meant that the +emphasis of AM, from the outset, has been on archival collections of the +basic material, and on making these collections themselves available, +rather than selected or heavily edited products. + +From AM's emphasis followed the questions with which the Workshop began: +who will use these materials, and in what form will they wish to use +them. But an even larger issue deserving mention, in GIFFORD's view, was +the phenomenal growth in Internet connectivity. He expressed the hope +that the prospect of greater interconnectedness than ever before would +lead to: 1) much more cooperative and mutually supportive endeavors; 2) +development of systems of shared and distributed responsibilities to +avoid duplication and to ensure accuracy and preservation of unique +materials; and 3) agreement on the necessary standards and development of +the appropriate directories and indices to make navigation +straightforward among the varied resources that are, and increasingly +will be, available. In this connection, GIFFORD requested that +participants reflect from the outset upon the sorts of outcomes they +thought the Workshop might have. Did those present constitute a group +with sufficient common interests to propose a next step or next steps, +and if so, what might those be? They would return to these questions the +following afternoon. + + ****** + ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ +FLEISCHHAUER * Core of Workshop concerns preparation and production of +materials * Special challenge in conversion of textual materials * +Quality versus quantity * Do the several groups represented share common +interests? * ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ + +Carl FLEISCHHAUER, coordinator, American Memory, Library of Congress, +emphasized that he would attempt to represent the people who perform some +of the work of converting or preparing materials and that the core of +the Workshop had to do with preparation and production. FLEISCHHAUER +then drew a distinction between the long term, when many things would be +available and connected in the ways that GIFFORD described, and the short +term, in which AM not only has wrestled with the issue of what is the +best course to pursue but also has faced a variety of technical +challenges. + +FLEISCHHAUER remarked AM's endeavors to deal with a wide range of library +formats, such as motion picture collections, sound-recording collections, +and pictorial collections of various sorts, especially collections of +photographs. In the course of these efforts, AM kept coming back to +textual materials--manuscripts or rare printed matter, bound materials, +etc. Text posed the greatest conversion challenge of all. Thus, the +genesis of the Workshop, which reflects the problems faced by AM. These +problems include physical problems. For example, those in the library +and archive business deal with collections made up of fragile and rare +manuscript items, bound materials, especially the notoriously brittle +bound materials of the late nineteenth century. These are precious +cultural artifacts, however, as well as interesting sources of +information, and LC desires to retain and conserve them. AM needs to +handle things without damaging them. Guillotining a book to run it +through a sheet feeder must be avoided at all costs. + +Beyond physical problems, issues pertaining to quality arose. For +example, the desire to provide users with a searchable text is affected +by the question of acceptable level of accuracy. One hundred percent +accuracy is tremendously expensive. On the other hand, the output of +optical character recognition (OCR) can be tremendously inaccurate. +Although AM has attempted to find a middle ground, uncertainty persists +as to whether or not it has discovered the right solution. + +Questions of quality arose concerning images as well. FLEISCHHAUER +contrasted the extremely high level of quality of the digital images in +the Cornell Xerox Project with AM's efforts to provide a browse-quality +or access-quality image, as opposed to an archival or preservation image. +FLEISCHHAUER therefore welcomed the opportunity to compare notes. + +FLEISCHHAUER observed in passing that conversations he had had about +networks have begun to signal that for various forms of media a +determination may be made that there is a browse-quality item, or a +distribution-and-access-quality item that may coexist in some systems +with a higher quality archival item that would be inconvenient to send +through the network because of its size. FLEISCHHAUER referred, of +course, to images more than to searchable text. + +As AM considered those questions, several conceptual issues arose: ought +AM occasionally to reproduce materials entirely through an image set, at +other times, entirely through a text set, and in some cases, a mix? +There probably would be times when the historical authenticity of an +artifact would require that its image be used. An image might be +desirable as a recourse for users if one could not provide 100-percent +accurate text. Again, AM wondered, as a practical matter, if a +distinction could be drawn between rare printed matter that might exist +in multiple collections--that is, in ten or fifteen libraries. In such +cases, the need for perfect reproduction would be less than for unique +items. Implicit in his remarks, FLEISCHHAUER conceded, was the admission +that AM has been tilting strongly towards quantity and drawing back a +little from perfect quality. That is, it seemed to AM that society would +be better served if more things were distributed by LC--even if they were +not quite perfect--than if fewer things, perfectly represented, were +distributed. This was stated as a proposition to be tested, with +responses to be gathered from users. + +In thinking about issues related to reproduction of materials and seeing +other people engaged in parallel activities, AM deemed it useful to +convene a conference. Hence, the Workshop. FLEISCHHAUER thereupon +surveyed the several groups represented: 1) the world of images (image +users and image makers); 2) the world of text and scholarship and, within +this group, those concerned with language--FLEISCHHAUER confessed to finding +delightful irony in the fact that some of the most advanced thinkers on +computerized texts are those dealing with ancient Greek and Roman materials; +3) the network world; and 4) the general world of library science, which +includes people interested in preservation and cataloging. + +FLEISCHHAUER concluded his remarks with special thanks to the David and +Lucile Packard Foundation for its support of the meeting, the American +Memory group, the Office for Scholarly Programs, the National +Demonstration Lab, and the Office of Special Events. He expressed the +hope that David Woodley Packard might be able to attend, noting that +Packard's work and the work of the foundation had sponsored a number of +projects in the text area. + + ****** + +SESSION I. CONTENT IN A NEW FORM: WHO WILL USE IT AND WHAT WILL THEY DO? + ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ +DALY * Acknowledgements * A new Latin authors disk * Effects of the new +technology on previous methods of research * ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ + +Serving as moderator, James DALY acknowledged the generosity of all the +presenters for giving of their time, counsel, and patience in planning +the Workshop, as well as of members of the American Memory project and +other Library of Congress staff, and the David and Lucile Packard +Foundation and its executive director, Colburn S. Wilbur. + +DALY then recounted his visit in March to the Center for Electronic Texts +in the Humanities (CETH) and the Department of Classics at Rutgers +University, where an old friend, Lowell Edmunds, introduced him to the +department's IBYCUS scholarly personal computer, and, in particular, the +new Latin CD-ROM, containing, among other things, almost all classical +Latin literary texts through A.D. 200. Packard Humanities Institute +(PHI), Los Altos, California, released this disk late in 1991, with a +nominal triennial licensing fee. + +Playing with the disk for an hour or so at Rutgers brought home to DALY +at once the revolutionizing impact of the new technology on his previous +methods of research. Had this disk been available two or three years +earlier, DALY contended, when he was engaged in preparing a commentary on +Book 10 of Virgil's Aeneid for Cambridge University Press, he would not +have required a forty-eight-square-foot table on which to spread the +numerous, most frequently consulted items, including some ten or twelve +concordances to key Latin authors, an almost equal number of lexica to +authors who lacked concordances, and where either lexica or concordances +were lacking, numerous editions of authors antedating and postdating Virgil. + +Nor, when checking each of the average six to seven words contained in +the Virgilian hexameter for its usage elsewhere in Virgil's works or +other Latin authors, would DALY have had to maintain the laborious +mechanical process of flipping through these concordances, lexica, and +editions each time. Nor would he have had to frequent as often the +Milton S. Eisenhower Library at the Johns Hopkins University to consult +the Thesaurus Linguae Latinae. Instead of devoting countless hours, or +the bulk of his research time, to gathering data concerning Virgil's use +of words, DALY--now freed by PHI's Latin authors disk from the +tyrannical, yet in some ways paradoxically happy scholarly drudgery-- +would have been able to devote that same bulk of time to analyzing and +interpreting Virgilian verbal usage. + +Citing Theodore Brunner, Gregory Crane, Elli MYLONAS, and Avra MICHELSON, +DALY argued that this reversal in his style of work, made possible by the +new technology, would perhaps have resulted in better, more productive +research. Indeed, even in the course of his browsing the Latin authors +disk at Rutgers, its powerful search, retrieval, and highlighting +capabilities suggested to him several new avenues of research into +Virgil's use of sound effects. This anecdotal account, DALY maintained, +may serve to illustrate in part the sudden and radical transformation +being wrought in the ways scholars work. + + ****** + +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ +MICHELSON * Elements related to scholarship and technology * Electronic +texts within the context of broader trends within information technology +and scholarly communication * Evaluation of the prospects for the use of +electronic texts * Relationship of electronic texts to processes of +scholarly communication in humanities research * New exchange formats +created by scholars * Projects initiated to increase scholarly access to +converted text * Trend toward making electronic resources available +through research and education networks * Changes taking place in +scholarly communication among humanities scholars * Network-mediated +scholarship transforming traditional scholarly practices * Key +information technology trends affecting the conduct of scholarly +communication over the next decade * The trend toward end-user computing +* The trend toward greater connectivity * Effects of these trends * Key +transformations taking place * Summary of principal arguments * +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ + +Avra MICHELSON, Archival Research and Evaluation Staff, National Archives +and Records Administration (NARA), argued that establishing who will use +electronic texts and what they will use them for involves a consideration +of both information technology and scholarship trends. This +consideration includes several elements related to scholarship and +technology: 1) the key trends in information technology that are most +relevant to scholarship; 2) the key trends in the use of currently +available technology by scholars in the nonscientific community; and 3) +the relationship between these two very distinct but interrelated trends. +The investment in understanding this relationship being made by +information providers, technologists, and public policy developers, as +well as by scholars themselves, seems to be pervasive and growing, +MICHELSON contended. She drew on collaborative work with Jeff Rothenberg +on the scholarly use of technology. + +MICHELSON sought to place the phenomenon of electronic texts within the +context of broader trends within information technology and scholarly +communication. She argued that electronic texts are of most use to +researchers to the extent that the researchers' working context (i.e., +their relevant bibliographic sources, collegial feedback, analytic tools, +notes, drafts, etc.), along with their field's primary and secondary +sources, also is accessible in electronic form and can be integrated in +ways that are unique to the on-line environment. + +Evaluation of the prospects for the use of electronic texts includes two +elements: 1) an examination of the ways in which researchers currently +are using electronic texts along with other electronic resources, and 2) +an analysis of key information technology trends that are affecting the +long-term conduct of scholarly communication. MICHELSON limited her +discussion of the use of electronic texts to the practices of humanists +and noted that the scientific community was outside the panel's overview. + +MICHELSON examined the nature of the current relationship of electronic +texts in particular, and electronic resources in general, to what she +maintained were, essentially, five processes of scholarly communication +in humanities research. Researchers 1) identify sources, 2) communicate +with their colleagues, 3) interpret and analyze data, 4) disseminate +their research findings, and 5) prepare curricula to instruct the next +generation of scholars and students. This examination would produce a +clearer understanding of the synergy among these five processes that +fuels the tendency of the use of electronic resources for one process to +stimulate its use for other processes of scholarly communication. + +For the first process of scholarly communication, the identification of +sources, MICHELSON remarked the opportunity scholars now enjoy to +supplement traditional word-of-mouth searches for sources among their +colleagues with new forms of electronic searching. So, for example, +instead of having to visit the library, researchers are able to explore +descriptions of holdings in their offices. Furthermore, if their own +institutions' holdings prove insufficient, scholars can access more than +200 major American library catalogues over Internet, including the +universities of California, Michigan, Pennsylvania, and Wisconsin. +Direct access to the bibliographic databases offers intellectual +empowerment to scholars by presenting a comprehensive means of browsing +through libraries from their homes and offices at their convenience. + +The second process of communication involves communication among +scholars. Beyond the most common methods of communication, scholars are +using E-mail and a variety of new electronic communications formats +derived from it for further academic interchange. E-mail exchanges are +growing at an astonishing rate, reportedly 15 percent a month. They +currently constitute approximately half the traffic on research and +education networks. Moreover, the global spread of E-mail has been so +rapid that it is now possible for American scholars to use it to +communicate with colleagues in close to 140 other countries. + +Other new exchange formats created by scholars and operating on Internet +include more than 700 conferences, with about 80 percent of these devoted +to topics in the social sciences and humanities. The rate of growth of +these scholarly electronic conferences also is astonishing. From l990 to +l991, 200 new conferences were identified on Internet. From October 1991 +to June 1992, an additional 150 conferences in the social sciences and +humanities were added to this directory of listings. Scholars have +established conferences in virtually every field, within every different +discipline. For example, there are currently close to 600 active social +science and humanities conferences on topics such as art and +architecture, ethnomusicology, folklore, Japanese culture, medical +education, and gifted and talented education. The appeal to scholars of +communicating through these conferences is that, unlike any other medium, +electronic conferences today provide a forum for global communication +with peers at the front end of the research process. + +Interpretation and analysis of sources constitutes the third process of +scholarly communication that MICHELSON discussed in terms of texts and +textual resources. The methods used to analyze sources fall somewhere on +a continuum from quantitative analysis to qualitative analysis. +Typically, evidence is culled and evaluated using methods drawn from both +ends of this continuum. At one end, quantitative analysis involves the +use of mathematical processes such as a count of frequencies and +distributions of occurrences or, on a higher level, regression analysis. +At the other end of the continuum, qualitative analysis typically +involves nonmathematical processes oriented toward language +interpretation or the building of theory. Aspects of this work involve +the processing--either manual or computational--of large and sometimes +massive amounts of textual sources, although the use of nontextual +sources as evidence, such as photographs, sound recordings, film footage, +and artifacts, is significant as well. + +Scholars have discovered that many of the methods of interpretation and +analysis that are related to both quantitative and qualitative methods +are processes that can be performed by computers. For example, computers +can count. They can count brush strokes used in a Rembrandt painting or +perform regression analysis for understanding cause and effect. By means +of advanced technologies, computers can recognize patterns, analyze text, +and model concepts. Furthermore, computers can complete these processes +faster with more sources and with greater precision than scholars who +must rely on manual interpretation of data. But if scholars are to use +computers for these processes, source materials must be in a form +amenable to computer-assisted analysis. For this reason many scholars, +once they have identified the sources that are key to their research, are +converting them to machine-readable form. Thus, a representative example +of the numerous textual conversion projects organized by scholars around +the world in recent years to support computational text analysis is the +TLG, the Thesaurus Linguae Graecae. This project is devoted to +converting the extant ancient texts of classical Greece. (Editor's note: +according to the TLG Newsletter of May l992, TLG was in use in thirty-two +different countries. This figure updates MICHELSON's previous count by one.) + +The scholars performing these conversions have been asked to recognize +that the electronic sources they are converting for one use possess value +for other research purposes as well. As a result, during the past few +years, humanities scholars have initiated a number of projects to +increase scholarly access to converted text. So, for example, the Text +Encoding Initiative (TEI), about which more is said later in the program, +was established as an effort by scholars to determine standard elements +and methods for encoding machine-readable text for electronic exchange. +In a second effort to facilitate the sharing of converted text, scholars +have created a new institution, the Center for Electronic Texts in the +Humanities (CETH). The center estimates that there are 8,000 series of +source texts in the humanities that have been converted to +machine-readable form worldwide. CETH is undertaking an international +search for converted text in the humanities, compiling it into an +electronic library, and preparing bibliographic descriptions of the +sources for the Research Libraries Information Network's (RLIN) +machine-readable data file. The library profession has begun to initiate +large conversion projects as well, such as American Memory. + +While scholars have been making converted text available to one another, +typically on disk or on CD-ROM, the clear trend is toward making these +resources available through research and education networks. Thus, the +American and French Research on the Treasury of the French Language +(ARTFL) and the Dante Project are already available on Internet. +MICHELSON summarized this section on interpretation and analysis by +noting that: 1) increasing numbers of humanities scholars in the library +community are recognizing the importance to the advancement of +scholarship of retrospective conversion of source materials in the arts +and humanities; and 2) there is a growing realization that making the +sources available on research and education networks maximizes their +usefulness for the analysis performed by humanities scholars. + +The fourth process of scholarly communication is dissemination of +research findings, that is, publication. Scholars are using existing +research and education networks to engineer a new type of publication: +scholarly-controlled journals that are electronically produced and +disseminated. Although such journals are still emerging as a +communication format, their number has grown, from approximately twelve +to thirty-six during the past year (July 1991 to June 1992). Most of +these electronic scholarly journals are devoted to topics in the +humanities. As with network conferences, scholarly enthusiasm for these +electronic journals stems from the medium's unique ability to advance +scholarship in a way that no other medium can do by supporting global +feedback and interchange, practically in real time, early in the research +process. Beyond scholarly journals, MICHELSON remarked the delivery of +commercial full-text products, such as articles in professional journals, +newsletters, magazines, wire services, and reference sources. These are +being delivered via on-line local library catalogues, especially through +CD-ROMs. Furthermore, according to MICHELSON, there is general optimism +that the copyright and fees issues impeding the delivery of full text on +existing research and education networks soon will be resolved. + +The final process of scholarly communication is curriculum development +and instruction, and this involves the use of computer information +technologies in two areas. The first is the development of +computer-oriented instructional tools, which includes simulations, +multimedia applications, and computer tools that are used to assist in +the analysis of sources in the classroom, etc. The Perseus Project, a +database that provides a multimedia curriculum on classical Greek +civilization, is a good example of the way in which entire curricula are +being recast using information technologies. It is anticipated that the +current difficulty in exchanging electronically computer-based +instructional software, which in turn makes it difficult for one scholar +to build upon the work of others, will be resolved before too long. +Stand-alone curricular applications that involve electronic text will be +sharable through networks, reinforcing their significance as intellectual +products as well as instructional tools. + +The second aspect of electronic learning involves the use of research and +education networks for distance education programs. Such programs +interactively link teachers with students in geographically scattered +locations and rely on the availability of electronic instructional +resources. Distance education programs are gaining wide appeal among +state departments of education because of their demonstrated capacity to +bring advanced specialized course work and an array of experts to many +classrooms. A recent report found that at least 32 states operated at +least one statewide network for education in 1991, with networks under +development in many of the remaining states. + +MICHELSON summarized this section by noting two striking changes taking +place in scholarly communication among humanities scholars. First is the +extent to which electronic text in particular, and electronic resources +in general, are being infused into each of the five processes described +above. As mentioned earlier, there is a certain synergy at work here. +The use of electronic resources for one process tends to stimulate its +use for other processes, because the chief course of movement is toward a +comprehensive on-line working context for humanities scholars that +includes on-line availability of key bibliographies, scholarly feedback, +sources, analytical tools, and publications. MICHELSON noted further +that the movement toward a comprehensive on-line working context for +humanities scholars is not new. In fact, it has been underway for more +than forty years in the humanities, since Father Roberto Busa began +developing an electronic concordance of the works of Saint Thomas Aquinas +in 1949. What we are witnessing today, MICHELSON contended, is not the +beginning of this on-line transition but, for at least some humanities +scholars, the turning point in the transition from a print to an +electronic working context. Coinciding with the on-line transition, the +second striking change is the extent to which research and education +networks are becoming the new medium of scholarly communication. The +existing Internet and the pending National Education and Research Network +(NREN) represent the new meeting ground where scholars are going for +bibliographic information, scholarly dialogue and feedback, the most +current publications in their field, and high-level educational +offerings. Traditional scholarly practices are undergoing tremendous +transformations as a result of the emergence and growing prominence of +what is called network-mediated scholarship. + +MICHELSON next turned to the second element of the framework she proposed +at the outset of her talk for evaluating the prospects for electronic +text, namely the key information technology trends affecting the conduct +of scholarly communication over the next decade: 1) end-user computing +and 2) connectivity. + +End-user computing means that the person touching the keyboard, or +performing computations, is the same as the person who initiates or +consumes the computation. The emergence of personal computers, along +with a host of other forces, such as ubiquitous computing, advances in +interface design, and the on-line transition, is prompting the consumers +of computation to do their own computing, and is thus rendering obsolete +the traditional distinction between end users and ultimate users. + +The trend toward end-user computing is significant to consideration of +the prospects for electronic texts because it means that researchers are +becoming more adept at doing their own computations and, thus, more +competent in the use of electronic media. By avoiding programmer +intermediaries, computation is becoming central to the researcher's +thought process. This direct involvement in computing is changing the +researcher's perspective on the nature of research itself, that is, the +kinds of questions that can be posed, the analytical methodologies that +can be used, the types and amount of sources that are appropriate for +analyses, and the form in which findings are presented. The trend toward +end-user computing means that, increasingly, electronic media and +computation are being infused into all processes of humanities +scholarship, inspiring remarkable transformations in scholarly +communication. + +The trend toward greater connectivity suggests that researchers are using +computation increasingly in network environments. Connectivity is +important to scholarship because it erases the distance that separates +students from teachers and scholars from their colleagues, while allowing +users to access remote databases, share information in many different +media, connect to their working context wherever they are, and +collaborate in all phases of research. + +The combination of the trend toward end-user computing and the trend +toward connectivity suggests that the scholarly use of electronic +resources, already evident among some researchers, will soon become an +established feature of scholarship. The effects of these trends, along +with ongoing changes in scholarly practices, point to a future in which +humanities researchers will use computation and electronic communication +to help them formulate ideas, access sources, perform research, +collaborate with colleagues, seek peer review, publish and disseminate +results, and engage in many other professional and educational activities. + +In summary, MICHELSON emphasized four points: 1) A portion of humanities +scholars already consider electronic texts the preferred format for +analysis and dissemination. 2) Scholars are using these electronic +texts, in conjunction with other electronic resources, in all the +processes of scholarly communication. 3) The humanities scholars' +working context is in the process of changing from print technology to +electronic technology, in many ways mirroring transformations that have +occurred or are occurring within the scientific community. 4) These +changes are occurring in conjunction with the development of a new +communication medium: research and education networks that are +characterized by their capacity to advance scholarship in a wholly unique +way. + +MICHELSON also reiterated her three principal arguments: l) Electronic +texts are best understood in terms of the relationship to other +electronic resources and the growing prominence of network-mediated +scholarship. 2) The prospects for electronic texts lie in their capacity +to be integrated into the on-line network of electronic resources that +comprise the new working context for scholars. 3) Retrospective conversion +of portions of the scholarly record should be a key strategy as information +providers respond to changes in scholarly communication practices. + + ****** + ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ +VECCIA * AM's evaluation project and public users of electronic resources +* AM and its design * Site selection and evaluating the Macintosh +implementation of AM * Characteristics of the six public libraries +selected * Characteristics of AM's users in these libraries * Principal +ways AM is being used * ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ + +Susan VECCIA, team leader, and Joanne FREEMAN, associate coordinator, +American Memory, Library of Congress, gave a joint presentation. First, +by way of introduction, VECCIA explained her and FREEMAN's roles in +American Memory (AM). Serving principally as an observer, VECCIA has +assisted with the evaluation project of AM, placing AM collections in a +variety of different sites around the country and helping to organize and +implement that project. FREEMAN has been an associate coordinator of AM +and has been involved principally with the interpretative materials, +preparing some of the electronic exhibits and printed historical +information that accompanies AM and that is requested by users. VECCIA +and FREEMAN shared anecdotal observations concerning AM with public users +of electronic resources. Notwithstanding a fairly structured evaluation +in progress, both VECCIA and FREEMAN chose not to report on specifics in +terms of numbers, etc., because they felt it was too early in the +evaluation project to do so. + +AM is an electronic archive of primary source materials from the Library +of Congress, selected collections representing a variety of formats-- +photographs, graphic arts, recorded sound, motion pictures, broadsides, +and soon, pamphlets and books. In terms of the design of this system, +the interpretative exhibits have been kept separate from the primary +resources, with good reason. Accompanying this collection are printed +documentation and user guides, as well as guides that FREEMAN prepared for +teachers so that they may begin using the content of the system at once. + +VECCIA described the evaluation project before talking about the public +users of AM, limiting her remarks to public libraries, because FREEMAN +would talk more specifically about schools from kindergarten to twelfth +grade (K-12). Having started in spring 1991, the evaluation currently +involves testing of the Macintosh implementation of AM. Since the +primary goal of this evaluation is to determine the most appropriate +audience or audiences for AM, very different sites were selected. This +makes evaluation difficult because of the varying degrees of technology +literacy among the sites. AM is situated in forty-four locations, of +which six are public libraries and sixteen are schools. Represented +among the schools are elementary, junior high, and high schools. +District offices also are involved in the evaluation, which will +conclude in summer 1993. + +VECCIA focused the remainder of her talk on the six public libraries, one +of which doubles as a state library. They represent a range of +geographic areas and a range of demographic characteristics. For +example, three are located in urban settings, two in rural settings, and +one in a suburban setting. A range of technical expertise is to be found +among these facilities as well. For example, one is an "Apple library of +the future," while two others are rural one-room libraries--in one, AM +sits at the front desk next to a tractor manual. + +All public libraries have been extremely enthusiastic, supportive, and +appreciative of the work that AM has been doing. VECCIA characterized +various users: Most users in public libraries describe themselves as +general readers; of the students who use AM in the public libraries, +those in fourth grade and above seem most interested. Public libraries +in rural sites tend to attract retired people, who have been highly +receptive to AM. Users tend to fall into two additional categories: +people interested in the content and historical connotations of these +primary resources, and those fascinated by the technology. The format +receiving the most comments has been motion pictures. The adult users in +public libraries are more comfortable with IBM computers, whereas young +people seem comfortable with either IBM or Macintosh, although most of +them seem to come from a Macintosh background. This same tendency is +found in the schools. + +What kinds of things do users do with AM? In a public library there are +two main goals or ways that AM is being used: as an individual learning +tool, and as a leisure activity. Adult learning was one area that VECCIA +would highlight as a possible application for a tool such as AM. She +described a patron of a rural public library who comes in every day on +his lunch hour and literally reads AM, methodically going through the +collection image by image. At the end of his hour he makes an electronic +bookmark, puts it in his pocket, and returns to work. The next day he +comes in and resumes where he left off. Interestingly, this man had +never been in the library before he used AM. In another small, rural +library, the coordinator reports that AM is a popular activity for some +of the older, retired people in the community, who ordinarily would not +use "those things,"--computers. Another example of adult learning in +public libraries is book groups, one of which, in particular, is using AM +as part of its reading on industrialization, integration, and urbanization +in the early 1900s. + +One library reports that a family is using AM to help educate their +children. In another instance, individuals from a local museum came in +to use AM to prepare an exhibit on toys of the past. These two examples +emphasize the mission of the public library as a cultural institution, +reaching out to people who do not have the same resources available to +those who live in a metropolitan area or have access to a major library. +One rural library reports that junior high school students in large +numbers came in one afternoon to use AM for entertainment. A number of +public libraries reported great interest among postcard collectors in the +Detroit collection, which was essentially a collection of images used on +postcards around the turn of the century. Train buffs are similarly +interested because that was a time of great interest in railroading. +People, it was found, relate to things that they know of firsthand. For +example, in both rural public libraries where AM was made available, +observers reported that the older people with personal remembrances of +the turn of the century were gravitating to the Detroit collection. +These examples served to underscore MICHELSON's observation re the +integration of electronic tools and ideas--that people learn best when +the material relates to something they know. + +VECCIA made the final point that in many cases AM serves as a +public-relations tool for the public libraries that are testing it. In +one case, AM is being used as a vehicle to secure additional funding for +the library. In another case, AM has served as an inspiration to the +staff of a major local public library in the South to think about ways to +make its own collection of photographs more accessible to the public. + + ****** + ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ +FREEMAN * AM and archival electronic resources in a school environment * +Questions concerning context * Questions concerning the electronic format +itself * Computer anxiety * Access and availability of the system * +Hardware * Strengths gained through the use of archival resources in +schools * ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ + +Reiterating an observation made by VECCIA, that AM is an archival +resource made up of primary materials with very little interpretation, +FREEMAN stated that the project has attempted to bridge the gap between +these bare primary materials and a school environment, and in that cause +has created guided introductions to AM collections. Loud demand from the +educational community, chiefly from teachers working with the upper +grades of elementary school through high school, greeted the announcement +that AM would be tested around the country. + +FREEMAN reported not only on what was learned about AM in a school +environment, but also on several universal questions that were raised +concerning archival electronic resources in schools. She discussed +several strengths of this type of material in a school environment as +opposed to a highly structured resource that offers a limited number of +paths to follow. + +FREEMAN first raised several questions about using AM in a school +environment. There is often some difficulty in developing a sense of +what the system contains. Many students sit down at a computer resource +and assume that, because AM comes from the Library of Congress, all of +American history is now at their fingertips. As a result of that sort of +mistaken judgment, some students are known to conclude that AM contains +nothing of use to them when they look for one or two things and do not +find them. It is difficult to discover that middle ground where one has +a sense of what the system contains. Some students grope toward the idea +of an archive, a new idea to them, since they have not previously +experienced what it means to have access to a vast body of somewhat +random information. + +Other questions raised by FREEMAN concerned the electronic format itself. +For instance, in a school environment it is often difficult both for +teachers and students to gain a sense of what it is they are viewing. +They understand that it is a visual image, but they do not necessarily +know that it is a postcard from the turn of the century, a panoramic +photograph, or even machine-readable text of an eighteenth-century +broadside, a twentieth-century printed book, or a nineteenth-century +diary. That distinction is often difficult for people in a school +environment to grasp. Because of that, it occasionally becomes difficult +to draw conclusions from what one is viewing. + +FREEMAN also noted the obvious fear of the computer, which constitutes a +difficulty in using an electronic resource. Though students in general +did not suffer from this anxiety, several older students feared that they +were computer-illiterate, an assumption that became self-fulfilling when +they searched for something but failed to find it. FREEMAN said she +believed that some teachers also fear computer resources, because they +believe they lack complete control. FREEMAN related the example of +teachers shooing away students because it was not their time to use the +system. This was a case in which the situation had to be extremely +structured so that the teachers would not feel that they had lost their +grasp on what the system contained. + +A final question raised by FREEMAN concerned access and availability of +the system. She noted the occasional existence of a gap in communication +between school librarians and teachers. Often AM sits in a school +library and the librarian is the person responsible for monitoring the +system. Teachers do not always take into their world new library +resources about which the librarian is excited. Indeed, at the sites +where AM had been used most effectively within a library, the librarian +was required to go to specific teachers and instruct them in its use. As +a result, several AM sites will have in-service sessions over a summer, +in the hope that perhaps, with a more individualized link, teachers will +be more likely to use the resource. + +A related issue in the school context concerned the number of +workstations available at any one location. Centralization of equipment +at the district level, with teachers invited to download things and walk +away with them, proved unsuccessful because the hours these offices were +open were also school hours. + +Another issue was hardware. As VECCIA observed, a range of sites exists, +some technologically advanced and others essentially acquiring their +first computer for the primary purpose of using it in conjunction with +AM's testing. Users at technologically sophisticated sites want even +more sophisticated hardware, so that they can perform even more +sophisticated tasks with the materials in AM. But once they acquire a +newer piece of hardware, they must learn how to use that also; at an +unsophisticated site it takes an extremely long time simply to become +accustomed to the computer, not to mention the program offered with the +computer. All of these small issues raise one large question, namely, +are systems like AM truly rewarding in a school environment, or do they +simply act as innovative toys that do little more than spark interest? + +FREEMAN contended that the evaluation project has revealed several strengths +that were gained through the use of archival resources in schools, including: + + * Psychic rewards from using AM as a vast, rich database, with + teachers assigning various projects to students--oral presentations, + written reports, a documentary, a turn-of-the-century newspaper-- + projects that start with the materials in AM but are completed using + other resources; AM thus is used as a research tool in conjunction + with other electronic resources, as well as with books and items in + the library where the system is set up. + + * Students are acquiring computer literacy in a humanities context. + + * This sort of system is overcoming the isolation between disciplines + that often exists in schools. For example, many English teachers are + requiring their students to write papers on historical topics + represented in AM. Numerous teachers have reported that their + students are learning critical thinking skills using the system. + + * On a broader level, AM is introducing primary materials, not only + to students but also to teachers, in an environment where often + simply none exist--an exciting thing for the students because it + helps them learn to conduct research, to interpret, and to draw + their own conclusions. In learning to conduct research and what it + means, students are motivated to seek knowledge. That relates to + another positive outcome--a high level of personal involvement of + students with the materials in this system and greater motivation to + conduct their own research and draw their own conclusions. + + * Perhaps the most ironic strength of these kinds of archival + electronic resources is that many of the teachers AM interviewed + were desperate, it is no exaggeration to say, not only for primary + materials but for unstructured primary materials. These would, they + thought, foster personally motivated research, exploration, and + excitement in their students. Indeed, these materials have done + just that. Ironically, however, this lack of structure produces + some of the confusion to which the newness of these kinds of + resources may also contribute. The key to effective use of archival + products in a school environment is a clear, effective introduction + to the system and to what it contains. + + ****** + ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ +DISCUSSION * Nothing known, quantitatively, about the number of +humanities scholars who must see the original versus those who would +settle for an edited transcript, or about the ways in which humanities +scholars are using information technology * Firm conclusions concerning +the manner and extent of the use of supporting materials in print +provided by AM to await completion of evaluative study * A listener's +reflections on additional applications of electronic texts * Role of +electronic resources in teaching elementary research skills to students * ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ + +During the discussion that followed the presentations by MICHELSON, +VECCIA, and FREEMAN, additional points emerged. + +LESK asked if MICHELSON could give any quantitative estimate of the +number of humanities scholars who must see or want to see the original, +or the best possible version of the material, versus those who typically +would settle for an edited transcript. While unable to provide a figure, +she offered her impressions as an archivist who has done some reference +work and has discussed this issue with other archivists who perform +reference, that those who use archives and those who use primary sources +for what would be considered very high-level scholarly research, as +opposed to, say, undergraduate papers, were few in number, especially +given the public interest in using primary sources to conduct +genealogical or avocational research and the kind of professional +research done by people in private industry or the federal government. +More important in MICHELSON's view was that, quantitatively, nothing is +known about the ways in which, for example, humanities scholars are using +information technology. No studies exist to offer guidance in creating +strategies. The most recent study was conducted in 1985 by the American +Council of Learned Societies (ACLS), and what it showed was that 50 +percent of humanities scholars at that time were using computers. That +constitutes the extent of our knowledge. + +Concerning AM's strategy for orienting people toward the scope of +electronic resources, FREEMAN could offer no hard conclusions at this +point, because she and her colleagues were still waiting to see, +particularly in the schools, what has been made of their efforts. Within +the system, however, AM has provided what are called electronic exhibits- +-such as introductions to time periods and materials--and these are +intended to offer a student user a sense of what a broadside is and what +it might tell her or him. But FREEMAN conceded that the project staff +would have to talk with students next year, after teachers have had a +summer to use the materials, and attempt to discover what the students +were learning from the materials. In addition, FREEMAN described +supporting materials in print provided by AM at the request of local +teachers during a meeting held at LC. These included time lines, +bibliographies, and other materials that could be reproduced on a +photocopier in a classroom. Teachers could walk away with and use these, +and in this way gain a better understanding of the contents. But again, +reaching firm conclusions concerning the manner and extent of their use +would have to wait until next year. + +As to the changes she saw occurring at the National Archives and Records +Administration (NARA) as a result of the increasing emphasis on +technology in scholarly research, MICHELSON stated that NARA at this +point was absorbing the report by her and Jeff Rothenberg addressing +strategies for the archival profession in general, although not for the +National Archives specifically. NARA is just beginning to establish its +role and what it can do. In terms of changes and initiatives that NARA +can take, no clear response could be given at this time. + +GREENFIELD remarked two trends mentioned in the session. Reflecting on +DALY's opening comments on how he could have used a Latin collection of +text in an electronic form, he said that at first he thought most scholars +would be unwilling to do that. But as he thought of that in terms of the +original meaning of research--that is, having already mastered these texts, +researching them for critical and comparative purposes--for the first time, +the electronic format made a lot of sense. GREENFIELD could envision +growing numbers of scholars learning the new technologies for that very +aspect of their scholarship and for convenience's sake. + +Listening to VECCIA and FREEMAN, GREENFIELD thought of an additional +application of electronic texts. He realized that AM could be used as a +guide to lead someone to original sources. Students cannot be expected +to have mastered these sources, things they have never known about +before. Thus, AM is leading them, in theory, to a vast body of +information and giving them a superficial overview of it, enabling them +to select parts of it. GREENFIELD asked if any evidence exists that this +resource will indeed teach the new user, the K-12 students, how to do +research. Scholars already know how to do research and are applying +these new tools. But he wondered why students would go beyond picking +out things that were most exciting to them. + +FREEMAN conceded the correctness of GREENFIELD's observation as applied +to a school environment. The risk is that a student would sit down at a +system, play with it, find some things of interest, and then walk away. +But in the relatively controlled situation of a school library, much will +depend on the instructions a teacher or a librarian gives a student. She +viewed the situation not as one of fine-tuning research skills but of +involving students at a personal level in understanding and researching +things. Given the guidance one can receive at school, it then becomes +possible to teach elementary research skills to students, which in fact +one particular librarian said she was teaching her fifth graders. +FREEMAN concluded that introducing the idea of following one's own path +of inquiry, which is essentially what research entails, involves more +than teaching specific skills. To these comments VECCIA added the +observation that the individual teacher and the use of a creative +resource, rather than AM itself, seemed to make the key difference. +Some schools and some teachers are making excellent use of the nature +of critical thinking and teaching skills, she said. + +Concurring with these remarks, DALY closed the session with the thought that +the more that producers produced for teachers and for scholars to use with +their students, the more successful their electronic products would prove. + + ****** + +SESSION II. SHOW AND TELL + +Jacqueline HESS, director, National Demonstration Laboratory, served as +moderator of the "show-and-tell" session. She noted that a +question-and-answer period would follow each presentation. + ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ +MYLONAS * Overview and content of Perseus * Perseus' primary materials +exist in a system-independent, archival form * A concession * Textual +aspects of Perseus * Tools to use with the Greek text * Prepared indices +and full-text searches in Perseus * English-Greek word search leads to +close study of words and concepts * Navigating Perseus by tracing down +indices * Using the iconography to perform research * ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ + +Elli MYLONAS, managing editor, Perseus Project, Harvard University, first +gave an overview of Perseus, a large, collaborative effort based at +Harvard University but with contributors and collaborators located at +numerous universities and colleges in the United States (e.g., Bowdoin, +Maryland, Pomona, Chicago, Virginia). Funded primarily by the +Annenberg/CPB Project, with additional funding from Apple, Harvard, and +the Packard Humanities Institute, among others, Perseus is a multimedia, +hypertextual database for teaching and research on classical Greek +civilization, which was released in February 1992 in version 1.0 and +distributed by Yale University Press. + +Consisting entirely of primary materials, Perseus includes ancient Greek +texts and translations of those texts; catalog entries--that is, museum +catalog entries, not library catalog entries--on vases, sites, coins, +sculpture, and archaeological objects; maps; and a dictionary, among +other sources. The number of objects and the objects for which catalog +entries exist are accompanied by thousands of color images, which +constitute a major feature of the database. Perseus contains +approximately 30 megabytes of text, an amount that will double in +subsequent versions. In addition to these primary materials, the Perseus +Project has been building tools for using them, making access and +navigation easier, the goal being to build part of the electronic +environment discussed earlier in the morning in which students or +scholars can work with their sources. + +The demonstration of Perseus will show only a fraction of the real work +that has gone into it, because the project had to face the dilemma of +what to enter when putting something into machine-readable form: should +one aim for very high quality or make concessions in order to get the +material in? Since Perseus decided to opt for very high quality, all of +its primary materials exist in a system-independent--insofar as it is +possible to be system-independent--archival form. Deciding what that +archival form would be and attaining it required much work and thought. +For example, all the texts are marked up in SGML, which will be made +compatible with the guidelines of the Text Encoding Initiative (TEI) when +they are issued. + +Drawings are postscript files, not meeting international standards, but +at least designed to go across platforms. Images, or rather the real +archival forms, consist of the best available slides, which are being +digitized. Much of the catalog material exists in database form--a form +that the average user could use, manipulate, and display on a personal +computer, but only at great cost. Thus, this is where the concession +comes in: All of this rich, well-marked-up information is stripped of +much of its content; the images are converted into bit-maps and the text +into small formatted chunks. All this information can then be imported +into HyperCard and run on a mid-range Macintosh, which is what Perseus +users have. This fact has made it possible for Perseus to attain wide +use fairly rapidly. Without those archival forms the HyperCard version +being demonstrated could not be made easily, and the project could not +have the potential to move to other forms and machines and software as +they appear, none of which information is in Perseus on the CD. + +Of the numerous multimedia aspects of Perseus, MYLONAS focused on the +textual. Part of what makes Perseus such a pleasure to use, MYLONAS +said, is this effort at seamless integration and the ability to move +around both visual and textual material. Perseus also made the decision +not to attempt to interpret its material any more than one interprets by +selecting. But, MYLONAS emphasized, Perseus is not courseware: No +syllabus exists. There is no effort to define how one teaches a topic +using Perseus, although the project may eventually collect papers by +people who have used it to teach. Rather, Perseus aims to provide +primary material in a kind of electronic library, an electronic sandbox, +so to say, in which students and scholars who are working on this +material can explore by themselves. With that, MYLONAS demonstrated +Perseus, beginning with the Perseus gateway, the first thing one sees +upon opening Perseus--an effort in part to solve the contextualizing +problem--which tells the user what the system contains. + +MYLONAS demonstrated only a very small portion, beginning with primary +texts and running off the CD-ROM. Having selected Aeschylus' Prometheus +Bound, which was viewable in Greek and English pretty much in the same +segments together, MYLONAS demonstrated tools to use with the Greek text, +something not possible with a book: looking up the dictionary entry form +of an unfamiliar word in Greek after subjecting it to Perseus' +morphological analysis for all the texts. After finding out about a +word, a user may then decide to see if it is used anywhere else in Greek. +Because vast amounts of indexing support all of the primary material, one +can find out where else all forms of a particular Greek word appear-- +often not a trivial matter because Greek is highly inflected. Further, +since the story of Prometheus has to do with the origins of sacrifice, a +user may wish to study and explore sacrifice in Greek literature; by +typing sacrifice into a small window, a user goes to the English-Greek +word list--something one cannot do without the computer (Perseus has +indexed the definitions of its dictionary)--the string sacrifice appears +in the definitions of these sixty-five words. One may then find out +where any of those words is used in the work(s) of a particular author. +The English definitions are not lemmatized. + +All of the indices driving this kind of usage were originally devised for +speed, MYLONAS observed; in other words, all that kind of information-- +all forms of all words, where they exist, the dictionary form they belong +to--were collected into databases, which will expedite searching. Then +it was discovered that one can do things searching in these databases +that could not be done searching in the full texts. Thus, although there +are full-text searches in Perseus, much of the work is done behind the +scenes, using prepared indices. Re the indexing that is done behind the +scenes, MYLONAS pointed out that without the SGML forms of the text, it +could not be done effectively. Much of this indexing is based on the +structures that are made explicit by the SGML tagging. + +It was found that one of the things many of Perseus' non-Greek-reading +users do is start from the dictionary and then move into the close study +of words and concepts via this kind of English-Greek word search, by which +means they might select a concept. This exercise has been assigned to +students in core courses at Harvard--to study a concept by looking for the +English word in the dictionary, finding the Greek words, and then finding +the words in the Greek but, of course, reading across in the English. +That tells them a great deal about what a translation means as well. + +Should one also wish to see images that have to do with sacrifice, that +person would go to the object key word search, which allows one to +perform a similar kind of index retrieval on the database of +archaeological objects. Without words, pictures are useless; Perseus has +not reached the point where it can do much with images that are not +cataloged. Thus, although it is possible in Perseus with text and images +to navigate by knowing where one wants to end up--for example, a +red-figure vase from the Boston Museum of Fine Arts--one can perform this +kind of navigation very easily by tracing down indices. MYLONAS +illustrated several generic scenes of sacrifice on vases. The features +demonstrated derived from Perseus 1.0; version 2.0 will implement even +better means of retrieval. + +MYLONAS closed by looking at one of the pictures and noting again that +one can do a great deal of research using the iconography as well as the +texts. For instance, students in a core course at Harvard this year were +highly interested in Greek concepts of foreigners and representations of +non-Greeks. So they performed a great deal of research, both with texts +(e.g., Herodotus) and with iconography on vases and coins, on how the +Greeks portrayed non-Greeks. At the same time, art historians who study +iconography were also interested, and were able to use this material. + + ****** + ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ +DISCUSSION * Indexing and searchability of all English words in Perseus * +Several features of Perseus 1.0 * Several levels of customization +possible * Perseus used for general education * Perseus' effects on +education * Contextual information in Perseus * Main challenge and +emphasis of Perseus * ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ + +Several points emerged in the discussion that followed MYLONAS's presentation. + +Although MYLONAS had not demonstrated Perseus' ability to cross-search +documents, she confirmed that all English words in Perseus are indexed +and can be searched. So, for example, sacrifice could have been searched +in all texts, the historical essay, and all the catalogue entries with +their descriptions--in short, in all of Perseus. + +Boolean logic is not in Perseus 1.0 but will be added to the next +version, although an effort is being made not to restrict Perseus to a +database in which one just performs searching, Boolean or otherwise. It +is possible to move laterally through the documents by selecting a word +one is interested in and selecting an area of information one is +interested in and trying to look that word up in that area. + +Since Perseus was developed in HyperCard, several levels of customization +are possible. Simple authoring tools exist that allow one to create +annotated paths through the information, which are useful for note-taking +and for guided tours for teaching purposes and for expository writing. +With a little more ingenuity it is possible to begin to add or substitute +material in Perseus. + +Perseus has not been used so much for classics education as for general +education, where it seemed to have an impact on the students in the core +course at Harvard (a general required course that students must take in +certain areas). Students were able to use primary material much more. + +The Perseus Project has an evaluation team at the University of Maryland +that has been documenting Perseus' effects on education. Perseus is very +popular, and anecdotal evidence indicates that it is having an effect at +places other than Harvard, for example, test sites at Ball State +University, Drury College, and numerous small places where opportunities +to use vast amounts of primary data may not exist. One documented effect +is that archaeological, anthropological, and philological research is +being done by the same person instead of by three different people. + +The contextual information in Perseus includes an overview essay, a +fairly linear historical essay on the fifth century B.C. that provides +links into the primary material (e.g., Herodotus, Thucydides, and +Plutarch), via small gray underscoring (on the screen) of linked +passages. These are handmade links into other material. + +To different extents, most of the production work was done at Harvard, +where the people and the equipment are located. Much of the +collaborative activity involved data collection and structuring, because +the main challenge and the emphasis of Perseus is the gathering of +primary material, that is, building a useful environment for studying +classical Greece, collecting data, and making it useful. +Systems-building is definitely not the main concern. Thus, much of the +work has involved writing essays, collecting information, rewriting it, +and tagging it. That can be done off site. The creative link for the +overview essay as well as for both systems and data was collaborative, +and was forged via E-mail and paper mail with professors at Pomona and +Bowdoin. + + ****** + ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ +CALALUCA * PLD's principal focus and contribution to scholarship * +Various questions preparatory to beginning the project * Basis for +project * Basic rule in converting PLD * Concerning the images in PLD * +Running PLD under a variety of retrieval softwares * Encoding the +database a hard-fought issue * Various features demonstrated * Importance +of user documentation * Limitations of the CD-ROM version * ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ + +Eric CALALUCA, vice president, Chadwyck-Healey, Inc., demonstrated a +software interpretation of the Patrologia Latina Database (PLD). PLD's +principal focus from the beginning of the project about three-and-a-half +years ago was on converting Migne's Latin series, and in the end, +CALALUCA suggested, conversion of the text will be the major contribution +to scholarship. CALALUCA stressed that, as possibly the only private +publishing organization at the Workshop, Chadwyck-Healey had sought no +federal funds or national foundation support before embarking upon the +project, but instead had relied upon a great deal of homework and +marketing to accomplish the task of conversion. + +Ever since the possibilities of computer-searching have emerged, scholars +in the field of late ancient and early medieval studies (philosophers, +theologians, classicists, and those studying the history of natural law +and the history of the legal development of Western civilization) have +been longing for a fully searchable version of Western literature, for +example, all the texts of Augustine and Bernard of Clairvaux and +Boethius, not to mention all the secondary and tertiary authors. + +Various questions arose, CALALUCA said. Should one convert Migne? +Should the database be encoded? Is it necessary to do that? How should +it be delivered? What about CD-ROM? Since this is a transitional +medium, why even bother to create software to run on a CD-ROM? Since +everybody knows people will be networking information, why go to the +trouble--which is far greater with CD-ROM than with the production of +magnetic data? Finally, how does one make the data available? Can many +of the hurdles to using electronic information that some publishers have +imposed upon databases be eliminated? + +The PLD project was based on the principle that computer-searching of +texts is most effective when it is done with a large database. Because +PLD represented a collection that serves so many disciplines across so +many periods, it was irresistible. + +The basic rule in converting PLD was to do no harm, to avoid the sins of +intrusion in such a database: no introduction of newer editions, no +on-the-spot changes, no eradicating of all possible falsehoods from an +edition. Thus, PLD is not the final act in electronic publishing for +this discipline, but simply the beginning. The conversion of PLD has +evoked numerous unanticipated questions: How will information be used? +What about networking? Can the rights of a database be protected? +Should one protect the rights of a database? How can it be made +available? + +Those converting PLD also tried to avoid the sins of omission, that is, +excluding portions of the collections or whole sections. What about the +images? PLD is full of images, some are extremely pious +nineteenth-century representations of the Fathers, while others contain +highly interesting elements. The goal was to cover all the text of Migne +(including notes, in Greek and in Hebrew, the latter of which, in +particular, causes problems in creating a search structure), all the +indices, and even the images, which are being scanned in separately +searchable files. + +Several North American institutions that have placed acquisition requests +for the PLD database have requested it in magnetic form without software, +which means they are already running it without software, without +anything demonstrated at the Workshop. + +What cannot practically be done is go back and reconvert and re-encode +data, a time-consuming and extremely costly enterprise. CALALUCA sees +PLD as a database that can, and should, be run under a variety of +retrieval softwares. This will permit the widest possible searches. +Consequently, the need to produce a CD-ROM of PLD, as well as to develop +software that could handle some 1.3 gigabyte of heavily encoded text, +developed out of conversations with collection development and reference +librarians who wanted software both compassionate enough for the +pedestrian but also capable of incorporating the most detailed +lexicographical studies that a user desires to conduct. In the end, the +encoding and conversion of the data will prove the most enduring +testament to the value of the project. + +The encoding of the database was also a hard-fought issue: Did the +database need to be encoded? Were there normative structures for encoding +humanist texts? Should it be SGML? What about the TEI--will it last, +will it prove useful? CALALUCA expressed some minor doubts as to whether +a data bank can be fully TEI-conformant. Every effort can be made, but +in the end to be TEI-conformant means to accept the need to make some +firm encoding decisions that can, indeed, be disputed. The TEI points +the publisher in a proper direction but does not presume to make all the +decisions for him or her. Essentially, the goal of encoding was to +eliminate, as much as possible, the hindrances to information-networking, +so that if an institution acquires a database, everybody associated with +the institution can have access to it. + +CALALUCA demonstrated a portion of Volume 160, because it had the most +anomalies in it. The software was created by Electronic Book +Technologies of Providence, RI, and is called Dynatext. The software +works only with SGML-coded data. + +Viewing a table of contents on the screen, the audience saw how Dynatext +treats each element as a book and attempts to simplify movement through a +volume. Familiarity with the Patrologia in print (i.e., the text, its +source, and the editions) will make the machine-readable versions highly +useful. (Software with a Windows application was sought for PLD, +CALALUCA said, because this was the main trend for scholarly use.) + +CALALUCA also demonstrated how a user can perform a variety of searches +and quickly move to any part of a volume; the look-up screen provides +some basic, simple word-searching. + +CALALUCA argued that one of the major difficulties is not the software. +Rather, in creating a product that will be used by scholars representing +a broad spectrum of computer sophistication, user documentation proves +to be the most important service one can provide. + +CALALUCA next illustrated a truncated search under mysterium within ten +words of virtus and how one would be able to find its contents throughout +the entire database. He said that the exciting thing about PLD is that +many of the applications in the retrieval software being written for it +will exceed the capabilities of the software employed now for the CD-ROM +version. The CD-ROM faces genuine limitations, in terms of speed and +comprehensiveness, in the creation of a retrieval software to run it. +CALALUCA said he hoped that individual scholars will download the data, +if they wish, to their personal computers, and have ready access to +important texts on a constant basis, which they will be able to use in +their research and from which they might even be able to publish. + +(CALALUCA explained that the blue numbers represented Migne's column numbers, +which are the standard scholarly references. Pulling up a note, he stated +that these texts were heavily edited and the image files would appear simply +as a note as well, so that one could quickly access an image.) + + ****** + ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ +FLEISCHHAUER/ERWAY * Several problems with which AM is still wrestling * +Various search and retrieval capabilities * Illustration of automatic +stemming and a truncated search * AM's attempt to find ways to connect +cataloging to the texts * AM's gravitation towards SGML * Striking a +balance between quantity and quality * How AM furnishes users recourse to +images * Conducting a search in a full-text environment * Macintosh and +IBM prototypes of AM * Multimedia aspects of AM * ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ + +A demonstration of American Memory by its coordinator, Carl FLEISCHHAUER, +and Ricky ERWAY, associate coordinator, Library of Congress, concluded +the morning session. Beginning with a collection of broadsides from the +Continental Congress and the Constitutional Convention, the only text +collection in a presentable form at the time of the Workshop, FLEISCHHAUER +highlighted several of the problems with which AM is still wrestling. +(In its final form, the disk will contain two collections, not only the +broadsides but also the full text with illustrations of a set of +approximately 300 African-American pamphlets from the period 1870 to 1910.) + +As FREEMAN had explained earlier, AM has attempted to use a small amount +of interpretation to introduce collections. In the present case, the +contractor, a company named Quick Source, in Silver Spring, MD., used +software called Toolbook and put together a modestly interactive +introduction to the collection. Like the two preceding speakers, +FLEISCHHAUER argued that the real asset was the underlying collection. + +FLEISCHHAUER proceeded to describe various search and retrieval +capabilities while ERWAY worked the computer. In this particular package +the "go to" pull-down allowed the user in effect to jump out of Toolbook, +where the interactive program was located, and enter the third-party +software used by AM for this text collection, which is called Personal +Librarian. This was the Windows version of Personal Librarian, a +software application put together by a company in Rockville, Md. + +Since the broadsides came from the Revolutionary War period, a search was +conducted using the words British or war, with the default operator reset +as or. FLEISCHHAUER demonstrated both automatic stemming (which finds +other forms of the same root) and a truncated search. One of Personal +Librarian's strongest features, the relevance ranking, was represented by +a chart that indicated how often words being sought appeared in +documents, with the one receiving the most "hits" obtaining the highest +score. The "hit list" that is supplied takes the relevance ranking into +account, making the first hit, in effect, the one the software has +selected as the most relevant example. + +While in the text of one of the broadside documents, FLEISCHHAUER +remarked AM's attempt to find ways to connect cataloging to the texts, +which it does in different ways in different manifestations. In the case +shown, the cataloging was pasted on: AM took MARC records that were +written as on-line records right into one of the Library's mainframe +retrieval programs, pulled them out, and handed them off to the contractor, +who massaged them somewhat to display them in the manner shown. One of +AM's questions is, Does the cataloguing normally performed in the mainframe +work in this context, or had AM ought to think through adjustments? + +FLEISCHHAUER made the additional point that, as far as the text goes, AM +has gravitated towards SGML (he pointed to the boldface in the upper part +of the screen). Although extremely limited in its ability to translate +or interpret SGML, Personal Librarian will furnish both bold and italics +on screen; a fairly easy thing to do, but it is one of the ways in which +SGML is useful. + +Striking a balance between quantity and quality has been a major concern +of AM, with accuracy being one of the places where project staff have +felt that less than 100-percent accuracy was not unacceptable. +FLEISCHHAUER cited the example of the standard of the rekeying industry, +namely 99.95 percent; as one service bureau informed him, to go from +99.95 to 100 percent would double the cost. + +FLEISCHHAUER next demonstrated how AM furnishes users recourse to images, +and at the same time recalled LESK's pointed question concerning the +number of people who would look at those images and the number who would +work only with the text. If the implication of LESK's question was +sound, FLEISCHHAUER said, it raised the stakes for text accuracy and +reduced the value of the strategy for images. + +Contending that preservation is always a bugaboo, FLEISCHHAUER +demonstrated several images derived from a scan of a preservation +microfilm that AM had made. He awarded a grade of C at best, perhaps a +C minus or a C plus, for how well it worked out. Indeed, the matter of +learning if other people had better ideas about scanning in general, and, +in particular, scanning from microfilm, was one of the factors that drove +AM to attempt to think through the agenda for the Workshop. Skew, for +example, was one of the issues that AM in its ignorance had not reckoned +would prove so difficult. + +Further, the handling of images of the sort shown, in a desktop computer +environment, involved a considerable amount of zooming and scrolling. +Ultimately, AM staff feel that perhaps the paper copy that is printed out +might be the most useful one, but they remain uncertain as to how much +on-screen reading users will do. + +Returning to the text, FLEISCHHAUER asked viewers to imagine a person who +might be conducting a search in a full-text environment. With this +scenario, he proceeded to illustrate other features of Personal Librarian +that he considered helpful; for example, it provides the ability to +notice words as one reads. Clicking the "include" button on the bottom +of the search window pops the words that have been highlighted into the +search. Thus, a user can refine the search as he or she reads, +re-executing the search and continuing to find things in the quest for +materials. This software not only contains relevance ranking, Boolean +operators, and truncation, it also permits one to perform word algebra, +so to say, where one puts two or three words in parentheses and links +them with one Boolean operator and then a couple of words in another set +of parentheses and asks for things within so many words of others. + +Until they became acquainted recently with some of the work being done in +classics, the AM staff had not realized that a large number of the +projects that involve electronic texts were being done by people with a +profound interest in language and linguistics. Their search strategies +and thinking are oriented to those fields, as is shown in particular by +the Perseus example. As amateur historians, the AM staff were thinking +more of searching for concepts and ideas than for particular words. +Obviously, FLEISCHHAUER conceded, searching for concepts and ideas and +searching for words may be two rather closely related things. + +While displaying several images, FLEISCHHAUER observed that the Macintosh +prototype built by AM contains a greater diversity of formats. Echoing a +previous speaker, he said that it was easier to stitch things together in +the Macintosh, though it tended to be a little more anemic in search and +retrieval. AM, therefore, increasingly has been investigating +sophisticated retrieval engines in the IBM format. + +FLEISCHHAUER demonstrated several additional examples of the prototype +interfaces: One was AM's metaphor for the network future, in which a +kind of reading-room graphic suggests how one would be able to go around +to different materials. AM contains a large number of photographs in +analog video form worked up from a videodisc, which enable users to make +copies to print or incorporate in digital documents. A frame-grabber is +built into the system, making it possible to bring an image into a window +and digitize or print it out. + +FLEISCHHAUER next demonstrated sound recording, which included texts. +Recycled from a previous project, the collection included sixty 78-rpm +phonograph records of political speeches that were made during and +immediately after World War I. These constituted approximately three +hours of audio, as AM has digitized it, which occupy 150 megabytes on a +CD. Thus, they are considerably compressed. From the catalogue card, +FLEISCHHAUER proceeded to a transcript of a speech with the audio +available and with highlighted text following it as it played. +A photograph has been added and a transcription made. + +Considerable value has been added beyond what the Library of Congress +normally would do in cataloguing a sound recording, which raises several +questions for AM concerning where to draw lines about how much value it can +afford to add and at what point, perhaps, this becomes more than AM could +reasonably do or reasonably wish to do. FLEISCHHAUER also demonstrated +a motion picture. As FREEMAN had reported earlier, the motion picture +materials have proved the most popular, not surprisingly. This says more +about the medium, he thought, than about AM's presentation of it. + +Because AM's goal was to bring together things that could be used by +historians or by people who were curious about history, +turn-of-the-century footage seemed to represent the most appropriate +collections from the Library of Congress in motion pictures. These were +the very first films made by Thomas Edison's company and some others at +that time. The particular example illustrated was a Biograph film, +brought in with a frame-grabber into a window. A single videodisc +contains about fifty titles and pieces of film from that period, all of +New York City. Taken together, AM believes, they provide an interesting +documentary resource. + + ****** + ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ +DISCUSSION * Using the frame-grabber in AM * Volume of material processed +and to be processed * Purpose of AM within LC * Cataloguing and the +nature of AM's material * SGML coding and the question of quality versus +quantity * ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ + +During the question-and-answer period that followed FLEISCHHAUER's +presentation, several clarifications were made. + +AM is bringing in motion pictures from a videodisc. The frame-grabber +devices create a window on a computer screen, which permits users to +digitize a single frame of the movie or one of the photographs. It +produces a crude, rough-and-ready image that high school students can +incorporate into papers, and that has worked very nicely in this way. + +Commenting on FLEISCHHAUER's assertion that AM was looking more at +searching ideas than words, MYLONAS argued that without words an idea +does not exist. FLEISCHHAUER conceded that he ought to have articulated +his point more clearly. MYLONAS stated that they were in fact both +talking about the same thing. By searching for words and by forcing +people to focus on the word, the Perseus Project felt that they would get +them to the idea. The way one reviews results is tailored more to one +kind of user than another. + +Concerning the total volume of material that has been processed in this +way, AM at this point has in retrievable form seven or eight collections, +all of them photographic. In the Macintosh environment, for example, +there probably are 35,000-40,000 photographs. The sound recordings +number sixty items. The broadsides number about 300 items. There are +500 political cartoons in the form of drawings. The motion pictures, as +individual items, number sixty to seventy. + +AM also has a manuscript collection, the life history portion of one of +the federal project series, which will contain 2,900 individual +documents, all first-person narratives. AM has in process about 350 +African-American pamphlets, or about 12,000 printed pages for the period +1870-1910. Also in the works are some 4,000 panoramic photographs. AM +has recycled a fair amount of the work done by LC's Prints and +Photographs Division during the Library's optical disk pilot project in +the 1980s. For example, a special division of LC has tooled up and +thought through all the ramifications of electronic presentation of +photographs. Indeed, they are wheeling them out in great barrel loads. +The purpose of AM within the Library, it is hoped, is to catalyze several +of the other special collection divisions which have no particular +experience with, in some cases, mixed feelings about, an activity such as +AM. Moreover, in many cases the divisions may be characterized as not +only lacking experience in "electronifying" things but also in automated +cataloguing. MARC cataloguing as practiced in the United States is +heavily weighted toward the description of monograph and serial +materials, but is much thinner when one enters the world of manuscripts +and things that are held in the Library's music collection and other +units. In response to a comment by LESK, that AM's material is very +heavily photographic, and is so primarily because individual records have +been made for each photograph, FLEISCHHAUER observed that an item-level +catalog record exists, for example, for each photograph in the Detroit +Publishing collection of 25,000 pictures. In the case of the Federal +Writers Project, for which nearly 3,000 documents exist, representing +information from twenty-six different states, AM with the assistance of +Karen STUART of the Manuscript Division will attempt to find some way not +only to have a collection-level record but perhaps a MARC record for each +state, which will then serve as an umbrella for the 100-200 documents +that come under it. But that drama remains to be enacted. The AM staff +is conservative and clings to cataloguing, though of course visitors tout +artificial intelligence and neural networks in a manner that suggests that +perhaps one need not have cataloguing or that much of it could be put aside. + +The matter of SGML coding, FLEISCHHAUER conceded, returned the discussion +to the earlier treated question of quality versus quantity in the Library +of Congress. Of course, text conversion can be done with 100-percent +accuracy, but it means that when one's holdings are as vast as LC's only +a tiny amount will be exposed, whereas permitting lower levels of +accuracy can lead to exposing or sharing larger amounts, but with the +quality correspondingly impaired. + + ****** + ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ +TWOHIG * A contrary experience concerning electronic options * Volume of +material in the Washington papers and a suggestion of David Packard * +Implications of Packard's suggestion * Transcribing the documents for the +CD-ROM * Accuracy of transcriptions * The CD-ROM edition of the Founding +Fathers documents * ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ + +Finding encouragement in a comment of MICHELSON's from the morning +session--that numerous people in the humanities were choosing electronic +options to do their work--Dorothy TWOHIG, editor, The Papers of George +Washington, opened her illustrated talk by noting that her experience +with literary scholars and numerous people in editing was contrary to +MICHELSON's. TWOHIG emphasized literary scholars' complete ignorance of +the technological options available to them or their reluctance or, in +some cases, their downright hostility toward these options. + +After providing an overview of the five Founding Fathers projects +(Jefferson at Princeton, Franklin at Yale, John Adams at the +Massachusetts Historical Society, and Madison down the hall from her at +the University of Virginia), TWOHIG observed that the Washington papers, +like all of the projects, include both sides of the Washington +correspondence and deal with some 135,000 documents to be published with +extensive annotation in eighty to eighty-five volumes, a project that +will not be completed until well into the next century. Thus, it was +with considerable enthusiasm several years ago that the Washington Papers +Project (WPP) greeted David Packard's suggestion that the papers of the +Founding Fathers could be published easily and inexpensively, and to the +great benefit of American scholarship, via CD-ROM. + +In pragmatic terms, funding from the Packard Foundation would expedite +the transcription of thousands of documents waiting to be put on disk in +the WPP offices. Further, since the costs of collecting, editing, and +converting the Founding Fathers documents into letterpress editions were +running into the millions of dollars, and the considerable staffs +involved in all of these projects were devoting their careers to +producing the work, the Packard Foundation's suggestion had a +revolutionary aspect: Transcriptions of the entire corpus of the +Founding Fathers papers would be available on CD-ROM to public and +college libraries, even high schools, at a fraction of the cost-- +$100-$150 for the annual license fee--to produce a limited university +press run of 1,000 of each volume of the published papers at $45-$150 per +printed volume. Given the current budget crunch in educational systems +and the corresponding constraints on librarians in smaller institutions +who wish to add these volumes to their collections, producing the +documents on CD-ROM would likely open a greatly expanded audience for the +papers. TWOHIG stressed, however, that development of the Founding +Fathers CD-ROM is still in its infancy. Serious software problems remain +to be resolved before the material can be put into readable form. + +Funding from the Packard Foundation resulted in a major push to +transcribe the 75,000 or so documents of the Washington papers remaining +to be transcribed onto computer disks. Slides illustrated several of the +problems encountered, for example, the present inability of CD-ROM to +indicate the cross-outs (deleted material) in eighteenth century +documents. TWOHIG next described documents from various periods in the +eighteenth century that have been transcribed in chronological order and +delivered to the Packard offices in California, where they are converted +to the CD-ROM, a process that is expected to consume five years to +complete (that is, reckoning from David Packard's suggestion made several +years ago, until about July 1994). TWOHIG found an encouraging +indication of the project's benefits in the ongoing use made by scholars +of the search functions of the CD-ROM, particularly in reducing the time +spent in manually turning the pages of the Washington papers. + +TWOHIG next furnished details concerning the accuracy of transcriptions. +For instance, the insertion of thousands of documents on the CD-ROM +currently does not permit each document to be verified against the +original manuscript several times as in the case of documents that appear +in the published edition. However, the transcriptions receive a cursory +check for obvious typos, the misspellings of proper names, and other +errors from the WPP CD-ROM editor. Eventually, all documents that appear +in the electronic version will be checked by project editors. Although +this process has met with opposition from some of the editors on the +grounds that imperfect work may leave their offices, the advantages in +making this material available as a research tool outweigh fears about the +misspelling of proper names and other relatively minor editorial matters. + +Completion of all five Founding Fathers projects (i.e., retrievability +and searchability of all of the documents by proper names, alternate +spellings, or varieties of subjects) will provide one of the richest +sources of this size for the history of the United States in the latter +part of the eighteenth century. Further, publication on CD-ROM will +allow editors to include even minutiae, such as laundry lists, not +included in the printed volumes. + +It seems possible that the extensive annotation provided in the printed +volumes eventually will be added to the CD-ROM edition, pending +negotiations with the publishers of the papers. At the moment, the +Founding Fathers CD-ROM is accessible only on the IBYCUS, a computer +developed out of the Thesaurus Linguae Graecae project and designed for +the use of classical scholars. There are perhaps 400 IBYCUS computers in +the country, most of which are in university classics departments. +Ultimately, it is anticipated that the CD-ROM edition of the Founding +Fathers documents will run on any IBM-compatible or Macintosh computer +with a CD-ROM drive.

(OCLC). The +joint venture between AAAS and OCLC owes its beginning to a +reorganization launched by the new chief executive officer at OCLC about +three years ago and combines the strengths of these two disparate +organizations. In short, OJCCT represents the process of scholarly +publishing on line. + +LEBRON next discussed several practices the on-line environment shares +with traditional publishing on hard copy--for example, peer review of +manuscripts--that are highly important in the academic world. LEBRON +noted in particular the implications of citation counts for tenure +committees and grants committees. In the traditional hard-copy +environment, citation counts are readily demonstrable, whereas the +on-line environment represents an ethereal medium to most academics. + +LEBRON remarked several technical and behavioral barriers to electronic +publishing, for instance, the problems in transmission created by special +characters or by complex graphics and halftones. In addition, she noted +economic limitations such as the storage costs of maintaining back issues +and market or audience education. + +Manuscripts cannot be uploaded to OJCCT, LEBRON explained, because it is +not a bulletin board or E-mail, forms of electronic transmission of +information that have created an ambience clouding people's understanding +of what the journal is attempting to do. OJCCT, which publishes +peer-reviewed medical articles dealing with the subject of clinical +trials, includes text, tabular material, and graphics, although at this +time it can transmit only line illustrations. + +Next, LEBRON described how AAAS and OCLC arrived at the subject of +clinical trials: It is 1) a highly statistical discipline that 2) does +not require halftones but can satisfy the needs of its audience with line +illustrations and graphic material, and 3) there is a need for the speedy +dissemination of high-quality research results. Clinical trials are +research activities that involve the administration of a test treatment +to some experimental unit in order to test its usefulness before it is +made available to the general population. LEBRON proceeded to give +additional information on OJCCT concerning its editor-in-chief, editorial +board, editorial content, and the types of articles it publishes +(including peer-reviewed research reports and reviews), as well as +features shared by other traditional hard-copy journals. + +Among the advantages of the electronic format are faster dissemination of +information, including raw data, and the absence of space constraints +because pages do not exist. (This latter fact creates an interesting +situation when it comes to citations.) Nor are there any issues. AAAS's +capacity to download materials directly from the journal to a +subscriber's printer, hard drive, or floppy disk helps ensure highly +accurate transcription. Other features of OJCCT include on-screen alerts +that allow linkage of subsequently published documents to the original +documents; on-line searching by subject, author, title, etc.; indexing of +every single word that appears in an article; viewing access to an +article by component (abstract, full text, or graphs); numbered +paragraphs to replace page counts; publication in Science every thirty +days of indexing of all articles published in the journal; +typeset-quality screens; and Hypertext links that enable subscribers to +bring up Medline abstracts directly without leaving the journal. + +After detailing the two primary ways to gain access to the journal, +through the OCLC network and Compuserv if one desires graphics or through +the Internet if just an ASCII file is desired, LEBRON illustrated the +speedy editorial process and the coding of the document using SGML tags +after it has been accepted for publication. She also gave an illustrated +tour of the journal, its search-and-retrieval capabilities in particular, +but also including problems associated with scanning in illustrations, +and the importance of on-screen alerts to the medical profession re +retractions or corrections, or more frequently, editorials, letters to +the editors, or follow-up reports. She closed by inviting the audience +to join AAAS on 1 July, when OJCCT was scheduled to go on-line. + + ****** + ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ +DISCUSSION * Additional features of OJCCT * ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ + +In the lengthy discussion that followed LEBRON's presentation, these +points emerged: + + * The SGML text can be tailored as users wish. + + * All these articles have a fairly simple document definition. + + * Document-type definitions (DTDs) were developed and given to OJCCT + for coding. + + * No articles will be removed from the journal. (Because there are + no back issues, there are no lost issues either. Once a subscriber + logs onto the journal he or she has access not only to the currently + published materials, but retrospectively to everything that has been + published in it. Thus the table of contents grows bigger. The date + of publication serves to distinguish between currently published + materials and older materials.) + + * The pricing system for the journal resembles that for most medical + journals: for 1992, $95 for a year, plus telecommunications charges + (there are no connect time charges); for 1993, $110 for the + entire year for single users, though the journal can be put on a + local area network (LAN). However, only one person can access the + journal at a time. Site licenses may come in the future. + + * AAAS is working closely with colleagues at OCLC to display + mathematical equations on screen. + + * Without compromising any steps in the editorial process, the + technology has reduced the time lag between when a manuscript is + originally submitted and the time it is accepted; the review process + does not differ greatly from the standard six-to-eight weeks + employed by many of the hard-copy journals. The process still + depends on people. + + * As far as a preservation copy is concerned, articles will be + maintained on the computer permanently and subscribers, as part of + their subscription, will receive a microfiche-quality archival copy + of everything published during that year; in addition, reprints can + be purchased in much the same way as in a hard-copy environment. + Hard copies are prepared but are not the primary medium for the + dissemination of the information. + + * Because OJCCT is not yet on line, it is difficult to know how many + people would simply browse through the journal on the screen as + opposed to downloading the whole thing and printing it out; a mix of + both types of users likely will result. + + ****** + ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ +PERSONIUS * Developments in technology over the past decade * The CLASS +Project * Advantages for technology and for the CLASS Project * +Developing a network application an underlying assumption of the project +* Details of the scanning process * Print-on-demand copies of books * +Future plans include development of a browsing tool * ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ + +Lynne PERSONIUS, assistant director, Cornell Information Technologies for +Scholarly Information Services, Cornell University, first commented on +the tremendous impact that developments in technology over the past ten +years--networking, in particular--have had on the way information is +handled, and how, in her own case, these developments have counterbalanced +Cornell's relative geographical isolation. Other significant technologies +include scanners, which are much more sophisticated than they were ten years +ago; mass storage and the dramatic savings that result from it in terms of +both space and money relative to twenty or thirty years ago; new and +improved printing technologies, which have greatly affected the distribution +of information; and, of course, digital technologies, whose applicability to +library preservation remains at issue. + +Given that context, PERSONIUS described the College Library Access and +Storage System (CLASS) Project, a library preservation project, +primarily, and what has been accomplished. Directly funded by the +Commission on Preservation and Access and by the Xerox Corporation, which +has provided a significant amount of hardware, the CLASS Project has been +working with a development team at Xerox to develop a software +application tailored to library preservation requirements. Within +Cornell, participants in the project have been working jointly with both +library and information technologies. The focus of the project has been +on reformatting and saving books that are in brittle condition. +PERSONIUS showed Workshop participants a brittle book, and described how +such books were the result of developments in papermaking around the +beginning of the Industrial Revolution. The papermaking process was +changed so that a significant amount of acid was introduced into the +actual paper itself, which deteriorates as it sits on library shelves. + +One of the advantages for technology and for the CLASS Project is that +the information in brittle books is mostly out of copyright and thus +offers an opportunity to work with material that requires library +preservation, and to create and work on an infrastructure to save the +material. Acknowledging the familiarity of those working in preservation +with this information, PERSONIUS noted that several things are being +done: the primary preservation technology used today is photocopying of +brittle material. Saving the intellectual content of the material is the +main goal. With microfilm copy, the intellectual content is preserved on +the assumption that in the future the image can be reformatted in any +other way that then exists. + +An underlying assumption of the CLASS Project from the beginning was +that it would develop a network application. Project staff scan books +at a workstation located in the library, near the brittle material. +An image-server filing system is located at a distance from that +workstation, and a printer is located in another building. All of the +materials digitized and stored on the image-filing system are cataloged +in the on-line catalogue. In fact, a record for each of these electronic +books is stored in the RLIN database so that a record exists of what is +in the digital library throughout standard catalogue procedures. In the +future, researchers working from their own workstations in their offices, +or their networks, will have access--wherever they might be--through a +request server being built into the new digital library. A second +assumption is that the preferred means of finding the material will be by +looking through a catalogue. PERSONIUS described the scanning process, +which uses a prototype scanner being developed by Xerox and which scans a +very high resolution image at great speed. Another significant feature, +because this is a preservation application, is the placing of the pages +that fall apart one for one on the platen. Ordinarily, a scanner could +be used with some sort of a document feeder, but because of this +application that is not feasible. Further, because CLASS is a +preservation application, after the paper replacement is made there, a +very careful quality control check is performed. An original book is +compared to the printed copy and verification is made, before proceeding, +that all of the image, all of the information, has been captured. Then, +a new library book is produced: The printed images are rebound by a +commercial binder and a new book is returned to the shelf. +Significantly, the books returned to the library shelves are beautiful +and useful replacements on acid-free paper that should last a long time, +in effect, the equivalent of preservation photocopies. Thus, the project +has a library of digital books. In essence, CLASS is scanning and +storing books as 600 dot-per-inch bit-mapped images, compressed using +Group 4 CCITT (i.e., the French acronym for International Consultative +Committee for Telegraph and Telephone) compression. They are stored as +TIFF files on an optical filing system that is composed of a database +used for searching and locating the books and an optical jukebox that +stores 64 twelve-inch platters. A very-high-resolution printed copy of +these books at 600 dots per inch is created, using a Xerox DocuTech +printer to make the paper replacements on acid-free paper. + +PERSONIUS maintained that the CLASS Project presents an opportunity to +introduce people to books as digital images by using a paper medium. +Books are returned to the shelves while people are also given the ability +to print on demand--to make their own copies of books. (PERSONIUS +distributed copies of an engineering journal published by engineering +students at Cornell around 1900 as an example of what a print-on-demand +copy of material might be like. This very cheap copy would be available +to people to use for their own research purposes and would bridge the gap +between an electronic work and the paper that readers like to have.) +PERSONIUS then attempted to illustrate a very early prototype of +networked access to this digital library. Xerox Corporation has +developed a prototype of a view station that can send images across the +network to be viewed. + +The particular library brought down for demonstration contained two +mathematics books. CLASS is developing and will spend the next year +developing an application that allows people at workstations to browse +the books. Thus, CLASS is developing a browsing tool, on the assumption +that users do not want to read an entire book from a workstation, but +would prefer to be able to look through and decide if they would like to +have a printed copy of it. + + ****** + ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ +DISCUSSION * Re retrieval software * "Digital file copyright" * Scanning +rate during production * Autosegmentation * Criteria employed in +selecting books for scanning * Compression and decompression of images * +OCR not precluded * ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ + +During the question-and-answer period that followed her presentation, +PERSONIUS made these additional points: + + * Re retrieval software, Cornell is developing a Unix-based server + as well as clients for the server that support multiple platforms + (Macintosh, IBM and Sun workstations), in the hope that people from + any of those platforms will retrieve books; a further operating + assumption is that standard interfaces will be used as much as + possible, where standards can be put in place, because CLASS + considers this retrieval software a library application and would + like to be able to look at material not only at Cornell but at other + institutions. + + * The phrase "digital file copyright by Cornell University" was + added at the advice of Cornell's legal staff with the caveat that it + probably would not hold up in court. Cornell does not want people + to copy its books and sell them but would like to keep them + available for use in a library environment for library purposes. + + * In production the scanner can scan about 300 pages per hour, + capturing 600 dots per inch. + + * The Xerox software has filters to scan halftone material and avoid + the moire patterns that occur when halftone material is scanned. + Xerox has been working on hardware and software that would enable + the scanner itself to recognize this situation and deal with it + appropriately--a kind of autosegmentation that would enable the + scanner to handle halftone material as well as text on a single page. + + * The books subjected to the elaborate process described above were + selected because CLASS is a preservation project, with the first 500 + books selected coming from Cornell's mathematics collection, because + they were still being heavily used and because, although they were + in need of preservation, the mathematics library and the mathematics + faculty were uncomfortable having them microfilmed. (They wanted a + printed copy.) Thus, these books became a logical choice for this + project. Other books were chosen by the project's selection committees + for experiments with the technology, as well as to meet a demand or need. + + * Images will be decompressed before they are sent over the line; at + this time they are compressed and sent to the image filing system + and then sent to the printer as compressed images; they are returned + to the workstation as compressed 600-dpi images and the workstation + decompresses and scales them for display--an inefficient way to + access the material though it works quite well for printing and + other purposes. + + * CLASS is also decompressing on Macintosh and IBM, a slow process + right now. Eventually, compression and decompression will take + place on an image conversion server. Trade-offs will be made, based + on future performance testing, concerning where the file is + compressed and what resolution image is sent. + + * OCR has not been precluded; images are being stored that have been + scanned at a high resolution, which presumably would suit them well + to an OCR process. Because the material being scanned is about 100 + years old and was printed with less-than-ideal technologies, very + early and preliminary tests have not produced good results. But the + project is capturing an image that is of sufficient resolution to be + subjected to OCR in the future. Moreover, the system architecture + and the system plan have a logical place to store an OCR image if it + has been captured. But that is not being done now. + + ****** + +SESSION III. DISTRIBUTION, NETWORKS, AND NETWORKING: OPTIONS FOR +DISSEMINATION + ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ +ZICH * Issues pertaining to CD-ROMs * Options for publishing in CD-ROM * ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ + +Robert ZICH, special assistant to the associate librarian for special +projects, Library of Congress, and moderator of this session, first noted +the blessed but somewhat awkward circumstance of having four very +distinguished people representing networks and networking or at least +leaning in that direction, while lacking anyone to speak from the +strongest possible background in CD-ROMs. ZICH expressed the hope that +members of the audience would join the discussion. He stressed the +subtitle of this particular session, "Options for Dissemination," and, +concerning CD-ROMs, the importance of determining when it would be wise +to consider dissemination in CD-ROM versus networks. A shopping list of +issues pertaining to CD-ROMs included: the grounds for selecting +commercial publishers, and in-house publication where possible versus +nonprofit or government publication. A similar list for networks +included: determining when one should consider dissemination through a +network, identifying the mechanisms or entities that exist to place items +on networks, identifying the pool of existing networks, determining how a +producer would choose between networks, and identifying the elements of +a business arrangement in a network. + +Options for publishing in CD-ROM: an outside publisher versus +self-publication. If an outside publisher is used, it can be nonprofit, +such as the Government Printing Office (GPO) or the National Technical +Information Service (NTIS), in the case of government. The pros and cons +associated with employing an outside publisher are obvious. Among the +pros, there is no trouble getting accepted. One pays the bill and, in +effect, goes one's way. Among the cons, when one pays an outside +publisher to perform the work, that publisher will perform the work it is +obliged to do, but perhaps without the production expertise and skill in +marketing and dissemination that some would seek. There is the body of +commercial publishers that do possess that kind of expertise in +distribution and marketing but that obviously are selective. In +self-publication, one exercises full control, but then one must handle +matters such as distribution and marketing. Such are some of the options +for publishing in the case of CD-ROM. + +In the case of technical and design issues, which are also important, +there are many matters which many at the Workshop already knew a good +deal about: retrieval system requirements and costs, what to do about +images, the various capabilities and platforms, the trade-offs between +cost and performance, concerns about local-area networkability, +interoperability, etc. + + ****** + ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ +LYNCH * Creating networked information is different from using networks +as an access or dissemination vehicle * Networked multimedia on a large +scale does not yet work * Typical CD-ROM publication model a two-edged +sword * Publishing information on a CD-ROM in the present world of +immature standards * Contrast between CD-ROM and network pricing * +Examples demonstrated earlier in the day as a set of insular information +gems * Paramount need to link databases * Layering to become increasingly +necessary * Project NEEDS and the issues of information reuse and active +versus passive use * X-Windows as a way of differentiating between +network access and networked information * Barriers to the distribution +of networked multimedia information * Need for good, real-time delivery +protocols * The question of presentation integrity in client-server +computing in the academic world * Recommendations for producing multimedia ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ + +Clifford LYNCH, director, Library Automation, University of California, +opened his talk with the general observation that networked information +constituted a difficult and elusive topic because it is something just +starting to develop and not yet fully understood. LYNCH contended that +creating genuinely networked information was different from using +networks as an access or dissemination vehicle and was more sophisticated +and more subtle. He invited the members of the audience to extrapolate, +from what they heard about the preceding demonstration projects, to what +sort of a world of electronics information--scholarly, archival, +cultural, etc.--they wished to end up with ten or fifteen years from now. +LYNCH suggested that to extrapolate directly from these projects would +produce unpleasant results. + +Putting the issue of CD-ROM in perspective before getting into +generalities on networked information, LYNCH observed that those engaged +in multimedia today who wish to ship a product, so to say, probably do +not have much choice except to use CD-ROM: networked multimedia on a +large scale basically does not yet work because the technology does not +exist. For example, anybody who has tried moving images around over the +Internet knows that this is an exciting touch-and-go process, a +fascinating and fertile area for experimentation, research, and +development, but not something that one can become deeply enthusiastic +about committing to production systems at this time. + +This situation will change, LYNCH said. He differentiated CD-ROM from +the practices that have been followed up to now in distributing data on +CD-ROM. For LYNCH the problem with CD-ROM is not its portability or its +slowness but the two-edged sword of having the retrieval application and +the user interface inextricably bound up with the data, which is the +typical CD-ROM publication model. It is not a case of publishing data +but of distributing a typically stand-alone, typically closed system, +all--software, user interface, and data--on a little disk. Hence, all +the between-disk navigational issues as well as the impossibility in most +cases of integrating data on one disk with that on another. Most CD-ROM +retrieval software does not network very gracefully at present. However, +in the present world of immature standards and lack of understanding of +what network information is or what the ground rules are for creating or +using it, publishing information on a CD-ROM does add value in a very +real sense. + +LYNCH drew a contrast between CD-ROM and network pricing and in doing so +highlighted something bizarre in information pricing. A large +institution such as the University of California has vendors who will +offer to sell information on CD-ROM for a price per year in four digits, +but for the same data (e.g., an abstracting and indexing database) on +magnetic tape, regardless of how many people may use it concurrently, +will quote a price in six digits. + +What is packaged with the CD-ROM in one sense adds value--a complete +access system, not just raw, unrefined information--although it is not +generally perceived that way. This is because the access software, +although it adds value, is viewed by some people, particularly in the +university environment where there is a very heavy commitment to +networking, as being developed in the wrong direction. + +Given that context, LYNCH described the examples demonstrated as a set of +insular information gems--Perseus, for example, offers nicely linked +information, but would be very difficult to integrate with other +databases, that is, to link together seamlessly with other source files +from other sources. It resembles an island, and in this respect is +similar to numerous stand-alone projects that are based on videodiscs, +that is, on the single-workstation concept. + +As scholarship evolves in a network environment, the paramount need will +be to link databases. We must link personal databases to public +databases, to group databases, in fairly seamless ways--which is +extremely difficult in the environments under discussion with copies of +databases proliferating all over the place. + +The notion of layering also struck LYNCH as lurking in several of the +projects demonstrated. Several databases in a sense constitute +information archives without a significant amount of navigation built in. +Educators, critics, and others will want a layered structure--one that +defines or links paths through the layers to allow users to reach +specific points. In LYNCH's view, layering will become increasingly +necessary, and not just within a single resource but across resources +(e.g., tracing mythology and cultural themes across several classics +databases as well as a database of Renaissance culture). This ability to +organize resources, to build things out of multiple other things on the +network or select pieces of it, represented for LYNCH one of the key +aspects of network information. + +Contending that information reuse constituted another significant issue, +LYNCH commended to the audience's attention Project NEEDS (i.e., National +Engineering Education Delivery System). This project's objective is to +produce a database of engineering courseware as well as the components +that can be used to develop new courseware. In a number of the existing +applications, LYNCH said, the issue of reuse (how much one can take apart +and reuse in other applications) was not being well considered. He also +raised the issue of active versus passive use, one aspect of which is +how much information will be manipulated locally by users. Most people, +he argued, may do a little browsing and then will wish to print. LYNCH +was uncertain how these resources would be used by the vast majority of +users in the network environment. + +LYNCH next said a few words about X-Windows as a way of differentiating +between network access and networked information. A number of the +applications demonstrated at the Workshop could be rewritten to use X +across the network, so that one could run them from any X-capable device- +-a workstation, an X terminal--and transact with a database across the +network. Although this opens up access a little, assuming one has enough +network to handle it, it does not provide an interface to develop a +program that conveniently integrates information from multiple databases. +X is a viewing technology that has limits. In a real sense, it is just a +graphical version of remote log-in across the network. X-type applications +represent only one step in the progression towards real access. + +LYNCH next discussed barriers to the distribution of networked multimedia +information. The heart of the problem is a lack of standards to provide +the ability for computers to talk to each other, retrieve information, +and shuffle it around fairly casually. At the moment, little progress is +being made on standards for networked information; for example, present +standards do not cover images, digital voice, and digital video. A +useful tool kit of exchange formats for basic texts is only now being +assembled. The synchronization of content streams (i.e., synchronizing a +voice track to a video track, establishing temporal relations between +different components in a multimedia object) constitutes another issue +for networked multimedia that is just beginning to receive attention. + +Underlying network protocols also need some work; good, real-time +delivery protocols on the Internet do not yet exist. In LYNCH's view, +highly important in this context is the notion of networked digital +object IDs, the ability of one object on the network to point to another +object (or component thereof) on the network. Serious bandwidth issues +also exist. LYNCH was uncertain if billion-bit-per-second networks would +prove sufficient if numerous people ran video in parallel. + +LYNCH concluded by offering an issue for database creators to consider, +as well as several comments about what might constitute good trial +multimedia experiments. In a networked information world the database +builder or service builder (publisher) does not exercise the same +extensive control over the integrity of the presentation; strange +programs "munge" with one's data before the user sees it. Serious +thought must be given to what guarantees integrity of presentation. Part +of that is related to where one draws the boundaries around a networked +information service. This question of presentation integrity in +client-server computing has not been stressed enough in the academic +world, LYNCH argued, though commercial service providers deal with it +regularly. + +Concerning multimedia, LYNCH observed that good multimedia at the moment +is hideously expensive to produce. He recommended producing multimedia +with either very high sale value, or multimedia with a very long life +span, or multimedia that will have a very broad usage base and whose +costs therefore can be amortized among large numbers of users. In this +connection, historical and humanistically oriented material may be a good +place to start, because it tends to have a longer life span than much of +the scientific material, as well as a wider user base. LYNCH noted, for +example, that American Memory fits many of the criteria outlined. He +remarked the extensive discussion about bringing the Internet or the +National Research and Education Network (NREN) into the K-12 environment +as a way of helping the American educational system. + +LYNCH closed by noting that the kinds of applications demonstrated struck +him as excellent justifications of broad-scale networking for K-12, but +that at this time no "killer" application exists to mobilize the K-12 +community to obtain connectivity. + + ****** + ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ +DISCUSSION * Dearth of genuinely interesting applications on the network +a slow-changing situation * The issue of the integrity of presentation in +a networked environment * Several reasons why CD-ROM software does not +network * ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ + +During the discussion period that followed LYNCH's presentation, several +additional points were made. + +LYNCH reiterated even more strongly his contention that, historically, +once one goes outside high-end science and the group of those who need +access to supercomputers, there is a great dearth of genuinely +interesting applications on the network. He saw this situation changing +slowly, with some of the scientific databases and scholarly discussion +groups and electronic journals coming on as well as with the availability +of Wide Area Information Servers (WAIS) and some of the databases that +are being mounted there. However, many of those things do not seem to +have piqued great popular interest. For instance, most high school +students of LYNCH's acquaintance would not qualify as devotees of serious +molecular biology. + +Concerning the issue of the integrity of presentation, LYNCH believed +that a couple of information providers have laid down the law at least on +certain things. For example, his recollection was that the National +Library of Medicine feels strongly that one needs to employ the +identifier field if he or she is to mount a database commercially. The +problem with a real networked environment is that one does not know who +is reformatting and reprocessing one's data when one enters a client +server mode. It becomes anybody's guess, for example, if the network +uses a Z39.50 server, or what clients are doing with one's data. A data +provider can say that his contract will only permit clients to have +access to his data after he vets them and their presentation and makes +certain it suits him. But LYNCH held out little expectation that the +network marketplace would evolve in that way, because it required too +much prior negotiation. + +CD-ROM software does not network for a variety of reasons, LYNCH said. +He speculated that CD-ROM publishers are not eager to have their products +really hook into wide area networks, because they fear it will make their +data suppliers nervous. Moreover, until relatively recently, one had to +be rather adroit to run a full TCP/IP stack plus applications on a +PC-size machine, whereas nowadays it is becoming easier as PCs grow +bigger and faster. LYNCH also speculated that software providers had not +heard from their customers until the last year or so, or had not heard +from enough of their customers. + + ****** + ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ +BESSER * Implications of disseminating images on the network; planning +the distribution of multimedia documents poses two critical +implementation problems * Layered approach represents the way to deal +with users' capabilities * Problems in platform design; file size and its +implications for networking * Transmission of megabyte size images +impractical * Compression and decompression at the user's end * Promising +trends for compression * A disadvantage of using X-Windows * A project at +the Smithsonian that mounts images on several networks * ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ + +Howard BESSER, School of Library and Information Science, University of +Pittsburgh, spoke primarily about multimedia, focusing on images and the +broad implications of disseminating them on the network. He argued that +planning the distribution of multimedia documents posed two critical +implementation problems, which he framed in the form of two questions: +1) What platform will one use and what hardware and software will users +have for viewing of the material? and 2) How can one deliver a +sufficiently robust set of information in an accessible format in a +reasonable amount of time? Depending on whether network or CD-ROM is the +medium used, this question raises different issues of storage, +compression, and transmission. + +Concerning the design of platforms (e.g., sound, gray scale, simple +color, etc.) and the various capabilities users may have, BESSER +maintained that a layered approach was the way to deal with users' +capabilities. A result would be that users with less powerful +workstations would simply have less functionality. He urged members of +the audience to advocate standards and accompanying software that handle +layered functionality across a wide variety of platforms. + +BESSER also addressed problems in platform design, namely, deciding how +large a machine to design for situations when the largest number of users +have the lowest level of the machine, and one desires higher +functionality. BESSER then proceeded to the question of file size and +its implications for networking. He discussed still images in the main. +For example, a digital color image that fills the screen of a standard +mega-pel workstation (Sun or Next) will require one megabyte of storage +for an eight-bit image or three megabytes of storage for a true color or +twenty-four-bit image. Lossless compression algorithms (that is, +computational procedures in which no data is lost in the process of +compressing [and decompressing] an image--the exact bit-representation is +maintained) might bring storage down to a third of a megabyte per image, +but not much further than that. The question of size makes it difficult +to fit an appropriately sized set of these images on a single disk or to +transmit them quickly enough on a network. + +With these full screen mega-pel images that constitute a third of a +megabyte, one gets 1,000-3,000 full-screen images on a one-gigabyte disk; +a standard CD-ROM represents approximately 60 percent of that. Storing +images the size of a PC screen (just 8 bit color) increases storage +capacity to 4,000-12,000 images per gigabyte; 60 percent of that gives +one the size of a CD-ROM, which in turn creates a major problem. One +cannot have full-screen, full-color images with lossless compression; one +must compress them or use a lower resolution. For megabyte-size images, +anything slower than a T-1 speed is impractical. For example, on a +fifty-six-kilobaud line, it takes three minutes to transfer a +one-megabyte file, if it is not compressed; and this speed assumes ideal +circumstances (no other user contending for network bandwidth). Thus, +questions of disk access, remote display, and current telephone +connection speed make transmission of megabyte-size images impractical. + +BESSER then discussed ways to deal with these large images, for example, +compression and decompression at the user's end. In this connection, the +issues of how much one is willing to lose in the compression process and +what image quality one needs in the first place are unknown. But what is +known is that compression entails some loss of data. BESSER urged that +more studies be conducted on image quality in different situations, for +example, what kind of images are needed for what kind of disciplines, and +what kind of image quality is needed for a browsing tool, an intermediate +viewing tool, and archiving. + +BESSER remarked two promising trends for compression: from a technical +perspective, algorithms that use what is called subjective redundancy +employ principles from visual psycho-physics to identify and remove +information from the image that the human eye cannot perceive; from an +interchange and interoperability perspective, the JPEG (i.e., Joint +Photographic Experts Group, an ISO standard) compression algorithms also +offer promise. These issues of compression and decompression, BESSER +argued, resembled those raised earlier concerning the design of different +platforms. Gauging the capabilities of potential users constitutes a +primary goal. BESSER advocated layering or separating the images from +the applications that retrieve and display them, to avoid tying them to +particular software. + +BESSER detailed several lessons learned from his work at Berkeley with +Imagequery, especially the advantages and disadvantages of using +X-Windows. In the latter category, for example, retrieval is tied +directly to one's data, an intolerable situation in the long run on a +networked system. Finally, BESSER described a project of Jim Wallace at +the Smithsonian Institution, who is mounting images in a extremely +rudimentary way on the Compuserv and Genie networks and is preparing to +mount them on America On Line. Although the average user takes over +thirty minutes to download these images (assuming a fairly fast modem), +nevertheless, images have been downloaded 25,000 times. + +BESSER concluded his talk with several comments on the business +arrangement between the Smithsonian and Compuserv. He contended that not +enough is known concerning the value of images. + + ****** + ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ +DISCUSSION * Creating digitized photographic collections nearly +impossible except with large organizations like museums * Need for study +to determine quality of images users will tolerate * ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ + +During the brief exchange between LESK and BESSER that followed, several +clarifications emerged. + +LESK argued that the photographers were far ahead of BESSER: It is +almost impossible to create such digitized photographic collections +except with large organizations like museums, because all the +photographic agencies have been going crazy about this and will not sign +licensing agreements on any sort of reasonable terms. LESK had heard +that National Geographic, for example, had tried to buy the right to use +some image in some kind of educational production for $100 per image, but +the photographers will not touch it. They want accounting and payment +for each use, which cannot be accomplished within the system. BESSER +responded that a consortium of photographers, headed by a former National +Geographic photographer, had started assembling its own collection of +electronic reproductions of images, with the money going back to the +cooperative. + +LESK contended that BESSER was unnecessarily pessimistic about multimedia +images, because people are accustomed to low-quality images, particularly +from video. BESSER urged the launching of a study to determine what +users would tolerate, what they would feel comfortable with, and what +absolutely is the highest quality they would ever need. Conceding that +he had adopted a dire tone in order to arouse people about the issue, +BESSER closed on a sanguine note by saying that he would not be in this +business if he did not think that things could be accomplished. + + ****** + ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ +LARSEN * Issues of scalability and modularity * Geometric growth of the +Internet and the role played by layering * Basic functions sustaining +this growth * A library's roles and functions in a network environment * +Effects of implementation of the Z39.50 protocol for information +retrieval on the library system * The trade-off between volumes of data +and its potential usage * A snapshot of current trends * ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ + +Ronald LARSEN, associate director for information technology, University +of Maryland at College Park, first addressed the issues of scalability +and modularity. He noted the difficulty of anticipating the effects of +orders-of-magnitude growth, reflecting on the twenty years of experience +with the Arpanet and Internet. Recalling the day's demonstrations of +CD-ROM and optical disk material, he went on to ask if the field has yet +learned how to scale new systems to enable delivery and dissemination +across large-scale networks. + +LARSEN focused on the geometric growth of the Internet from its inception +circa 1969 to the present, and the adjustments required to respond to +that rapid growth. To illustrate the issue of scalability, LARSEN +considered computer networks as including three generic components: +computers, network communication nodes, and communication media. Each +component scales (e.g., computers range from PCs to supercomputers; +network nodes scale from interface cards in a PC through sophisticated +routers and gateways; and communication media range from 2,400-baud +dial-up facilities through 4.5-Mbps backbone links, and eventually to +multigigabit-per-second communication lines), and architecturally, the +components are organized to scale hierarchically from local area networks +to international-scale networks. Such growth is made possible by +building layers of communication protocols, as BESSER pointed out. +By layering both physically and logically, a sense of scalability is +maintained from local area networks in offices, across campuses, through +bridges, routers, campus backbones, fiber-optic links, etc., up into +regional networks and ultimately into national and international +networks. + +LARSEN then illustrated the geometric growth over a two-year period-- +through September 1991--of the number of networks that comprise the +Internet. This growth has been sustained largely by the availability of +three basic functions: electronic mail, file transfer (ftp), and remote +log-on (telnet). LARSEN also reviewed the growth in the kind of traffic +that occurs on the network. Network traffic reflects the joint contributions +of a larger population of users and increasing use per user. Today one sees +serious applications involving moving images across the network--a rarity +ten years ago. LARSEN recalled and concurred with BESSER's main point +that the interesting problems occur at the application level. + +LARSEN then illustrated a model of a library's roles and functions in a +network environment. He noted, in particular, the placement of on-line +catalogues onto the network and patrons obtaining access to the library +increasingly through local networks, campus networks, and the Internet. +LARSEN supported LYNCH's earlier suggestion that we need to address +fundamental questions of networked information in order to build +environments that scale in the information sense as well as in the +physical sense. + +LARSEN supported the role of the library system as the access point into +the nation's electronic collections. Implementation of the Z39.50 +protocol for information retrieval would make such access practical and +feasible. For example, this would enable patrons in Maryland to search +California libraries, or other libraries around the world that are +conformant with Z39.50 in a manner that is familiar to University of +Maryland patrons. This client-server model also supports moving beyond +secondary content into primary content. (The notion of how one links +from secondary content to primary content, LARSEN said, represents a +fundamental problem that requires rigorous thought.) After noting +numerous network experiments in accessing full-text materials, including +projects supporting the ordering of materials across the network, LARSEN +revisited the issue of transmitting high-density, high-resolution color +images across the network and the large amounts of bandwidth they +require. He went on to address the bandwidth and synchronization +problems inherent in sending full-motion video across the network. + +LARSEN illustrated the trade-off between volumes of data in bytes or +orders of magnitude and the potential usage of that data. He discussed +transmission rates (particularly, the time it takes to move various forms +of information), and what one could do with a network supporting +multigigabit-per-second transmission. At the moment, the network +environment includes a composite of data-transmission requirements, +volumes and forms, going from steady to bursty (high-volume) and from +very slow to very fast. This aggregate must be considered in the design, +construction, and operation of multigigabyte networks. + +LARSEN's objective is to use the networks and library systems now being +constructed to increase access to resources wherever they exist, and +thus, to evolve toward an on-line electronic virtual library. + +LARSEN concluded by offering a snapshot of current trends: continuing +geometric growth in network capacity and number of users; slower +development of applications; and glacial development and adoption of +standards. The challenge is to design and develop each new application +system with network access and scalability in mind. + + ****** + ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ +BROWNRIGG * Access to the Internet cannot be taken for granted * Packet +radio and the development of MELVYL in 1980-81 in the Division of Library +Automation at the University of California * Design criteria for packet +radio * A demonstration project in San Diego and future plans * Spread +spectrum * Frequencies at which the radios will run and plans to +reimplement the WAIS server software in the public domain * Need for an +infrastructure of radios that do not move around * ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ + +Edwin BROWNRIGG, executive director, Memex Research Institute, first +polled the audience in order to seek out regular users of the Internet as +well as those planning to use it some time in the future. With nearly +everybody in the room falling into one category or the other, BROWNRIGG +made a point re access, namely that numerous individuals, especially those +who use the Internet every day, take for granted their access to it, the +speeds with which they are connected, and how well it all works. +However, as BROWNRIGG discovered between 1987 and 1989 in Australia, +if one wants access to the Internet but cannot afford it or has some +physical boundary that prevents her or him from gaining access, it can +be extremely frustrating. He suggested that because of economics and +physical barriers we were beginning to create a world of haves and have-nots +in the process of scholarly communication, even in the United States. + +BROWNRIGG detailed the development of MELVYL in academic year 1980-81 in +the Division of Library Automation at the University of California, in +order to underscore the issue of access to the system, which at the +outset was extremely limited. In short, the project needed to build a +network, which at that time entailed use of satellite technology, that is, +putting earth stations on campus and also acquiring some terrestrial links +from the State of California's microwave system. The installation of +satellite links, however, did not solve the problem (which actually +formed part of a larger problem involving politics and financial resources). +For while the project team could get a signal onto a campus, it had no means +of distributing the signal throughout the campus. The solution involved +adopting a recent development in wireless communication called packet radio, +which combined the basic notion of packet-switching with radio. The project +used this technology to get the signal from a point on campus where it +came down, an earth station for example, into the libraries, because it +found that wiring the libraries, especially the older marble buildings, +would cost $2,000-$5,000 per terminal. + +BROWNRIGG noted that, ten years ago, the project had neither the public +policy nor the technology that would have allowed it to use packet radio +in any meaningful way. Since then much had changed. He proceeded to +detail research and development of the technology, how it is being +deployed in California, and what direction he thought it would take. +The design criteria are to produce a high-speed, one-time, low-cost, +high-quality, secure, license-free device (packet radio) that one can +plug in and play today, forget about it, and have access to the Internet. +By high speed, BROWNRIGG meant 1 megabyte and 1.5 megabytes. Those units +have been built, he continued, and are in the process of being +type-certified by an independent underwriting laboratory so that they can +be type-licensed by the Federal Communications Commission. As is the +case with citizens band, one will be able to purchase a unit and not have +to worry about applying for a license. + +The basic idea, BROWNRIGG elaborated, is to take high-speed radio data +transmission and create a backbone network that at certain strategic +points in the network will "gateway" into a medium-speed packet radio +(i.e., one that runs at 38.4 kilobytes), so that perhaps by 1994-1995 +people, like those in the audience for the price of a VCR could purchase +a medium-speed radio for the office or home, have full network connectivity +to the Internet, and partake of all its services, with no need for an FCC +license and no regular bill from the local common carrier. BROWNRIGG +presented several details of a demonstration project currently taking +place in San Diego and described plans, pending funding, to install a +full-bore network in the San Francisco area. This network will have 600 +nodes running at backbone speeds, and 100 of these nodes will be libraries, +which in turn will be the gateway ports to the 38.4 kilobyte radios that +will give coverage for the neighborhoods surrounding the libraries. + +BROWNRIGG next explained Part 15.247, a new rule within Title 47 of the +Code of Federal Regulations enacted by the FCC in 1985. This rule +challenged the industry, which has only now risen to the occasion, to +build a radio that would run at no more than one watt of output power and +use a fairly exotic method of modulating the radio wave called spread +spectrum. Spread spectrum in fact permits the building of networks so +that numerous data communications can occur simultaneously, without +interfering with each other, within the same wide radio channel. + +BROWNRIGG explained that the frequencies at which the radios would run +are very short wave signals. They are well above standard microwave and +radar. With a radio wave that small, one watt becomes a tremendous punch +per bit and thus makes transmission at reasonable speed possible. In +order to minimize the potential for congestion, the project is +undertaking to reimplement software which has been available in the +networking business and is taken for granted now, for example, TCP/IP, +routing algorithms, bridges, and gateways. In addition, the project +plans to take the WAIS server software in the public domain and +reimplement it so that one can have a WAIS server on a Mac instead of a +Unix machine. The Memex Research Institute believes that libraries, in +particular, will want to use the WAIS servers with packet radio. This +project, which has a team of about twelve people, will run through 1993 +and will include the 100 libraries already mentioned as well as other +professionals such as those in the medical profession, engineering, and +law. Thus, the need is to create an infrastructure of radios that do not +move around, which, BROWNRIGG hopes, will solve a problem not only for +libraries but for individuals who, by and large today, do not have access +to the Internet from their homes and offices. + + ****** + ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ +DISCUSSION * Project operating frequencies * ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ + +During a brief discussion period, which also concluded the day's +proceedings, BROWNRIGG stated that the project was operating in four +frequencies. The slow speed is operating at 435 megahertz, and it would +later go up to 920 megahertz. With the high-speed frequency, the +one-megabyte radios will run at 2.4 gigabits, and 1.5 will run at 5.7. +At 5.7, rain can be a factor, but it would have to be tropical rain, +unlike what falls in most parts of the United States. + + ****** + +SESSION IV. IMAGE CAPTURE, TEXT CAPTURE, OVERVIEW OF TEXT AND + IMAGE STORAGE FORMATS + +William HOOTON, vice president of operations, I-NET, moderated this session. + ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ +KENNEY * Factors influencing development of CXP * Advantages of using +digital technology versus photocopy and microfilm * A primary goal of +CXP; publishing challenges * Characteristics of copies printed * Quality +of samples achieved in image capture * Several factors to be considered +in choosing scanning * Emphasis of CXP on timely and cost-effective +production of black-and-white printed facsimiles * Results of producing +microfilm from digital files * Advantages of creating microfilm * Details +concerning production * Costs * Role of digital technology in library +preservation * ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ + +Anne KENNEY, associate director, Department of Preservation and +Conservation, Cornell University, opened her talk by observing that the +Cornell Xerox Project (CXP) has been guided by the assumption that the +ability to produce printed facsimiles or to replace paper with paper +would be important, at least for the present generation of users and +equipment. She described three factors that influenced development of +the project: 1) Because the project has emphasized the preservation of +deteriorating brittle books, the quality of what was produced had to be +sufficiently high to return a paper replacement to the shelf. CXP was +only interested in using: 2) a system that was cost-effective, which +meant that it had to be cost-competitive with the processes currently +available, principally photocopy and microfilm, and 3) new or currently +available product hardware and software. + +KENNEY described the advantages that using digital technology offers over +both photocopy and microfilm: 1) The potential exists to create a higher +quality reproduction of a deteriorating original than conventional +light-lens technology. 2) Because a digital image is an encoded +representation, it can be reproduced again and again with no resulting +loss of quality, as opposed to the situation with light-lens processes, +in which there is discernible difference between a second and a +subsequent generation of an image. 3) A digital image can be manipulated +in a number of ways to improve image capture; for example, Xerox has +developed a windowing application that enables one to capture a page +containing both text and illustrations in a manner that optimizes the +reproduction of both. (With light-lens technology, one must choose which +to optimize, text or the illustration; in preservation microfilming, the +current practice is to shoot an illustrated page twice, once to highlight +the text and the second time to provide the best capture for the +illustration.) 4) A digital image can also be edited, density levels +adjusted to remove underlining and stains, and to increase legibility for +faint documents. 5) On-screen inspection can take place at the time of +initial setup and adjustments made prior to scanning, factors that +substantially reduce the number of retakes required in quality control. + +A primary goal of CXP has been to evaluate the paper output printed on +the Xerox DocuTech, a high-speed printer that produces 600-dpi pages from +scanned images at a rate of 135 pages a minute. KENNEY recounted several +publishing challenges to represent faithful and legible reproductions of +the originals that the 600-dpi copy for the most part successfully +captured. For example, many of the deteriorating volumes in the project +were heavily illustrated with fine line drawings or halftones or came in +languages such as Japanese, in which the buildup of characters comprised +of varying strokes is difficult to reproduce at lower resolutions; a +surprising number of them came with annotations and mathematical +formulas, which it was critical to be able to duplicate exactly. + +KENNEY noted that 1) the copies are being printed on paper that meets the +ANSI standards for performance, 2) the DocuTech printer meets the machine +and toner requirements for proper adhesion of print to page, as described +by the National Archives, and thus 3) paper product is considered to be +the archival equivalent of preservation photocopy. + +KENNEY then discussed several samples of the quality achieved in the +project that had been distributed in a handout, for example, a copy of a +print-on-demand version of the 1911 Reed lecture on the steam turbine, +which contains halftones, line drawings, and illustrations embedded in +text; the first four loose pages in the volume compared the capture +capabilities of scanning to photocopy for a standard test target, the +IEEE standard 167A 1987 test chart. In all instances scanning proved +superior to photocopy, though only slightly more so in one. + +Conceding the simplistic nature of her review of the quality of scanning +to photocopy, KENNEY described it as one representation of the kinds of +settings that could be used with scanning capabilities on the equipment +CXP uses. KENNEY also pointed out that CXP investigated the quality +achieved with binary scanning only, and noted the great promise in gray +scale and color scanning, whose advantages and disadvantages need to be +examined. She argued further that scanning resolutions and file formats +can represent a complex trade-off between the time it takes to capture +material, file size, fidelity to the original, and on-screen display; and +printing and equipment availability. All these factors must be taken +into consideration. + +CXP placed primary emphasis on the production in a timely and +cost-effective manner of printed facsimiles that consisted largely of +black-and-white text. With binary scanning, large files may be +compressed efficiently and in a lossless manner (i.e., no data is lost in +the process of compressing [and decompressing] an image--the exact +bit-representation is maintained) using Group 4 CCITT (i.e., the French +acronym for International Consultative Committee for Telegraph and +Telephone) compression. CXP was getting compression ratios of about +forty to one. Gray-scale compression, which primarily uses JPEG, is much +less economical and can represent a lossy compression (i.e., not +lossless), so that as one compresses and decompresses, the illustration +is subtly changed. While binary files produce a high-quality printed +version, it appears 1) that other combinations of spatial resolution with +gray and/or color hold great promise as well, and 2) that gray scale can +represent a tremendous advantage for on-screen viewing. The quality +associated with binary and gray scale also depends on the equipment used. +For instance, binary scanning produces a much better copy on a binary +printer. + +Among CXP's findings concerning the production of microfilm from digital +files, KENNEY reported that the digital files for the same Reed lecture +were used to produce sample film using an electron beam recorder. The +resulting film was faithful to the image capture of the digital files, +and while CXP felt that the text and image pages represented in the Reed +lecture were superior to that of the light-lens film, the resolution +readings for the 600 dpi were not as high as standard microfilming. +KENNEY argued that the standards defined for light-lens technology are +not totally transferable to a digital environment. Moreover, they are +based on definition of quality for a preservation copy. Although making +this case will prove to be a long, uphill struggle, CXP plans to continue +to investigate the issue over the course of the next year. + +KENNEY concluded this portion of her talk with a discussion of the +advantages of creating film: it can serve as a primary backup and as a +preservation master to the digital file; it could then become the print +or production master and service copies could be paper, film, optical +disks, magnetic media, or on-screen display. + +Finally, KENNEY presented details re production: + + * Development and testing of a moderately-high resolution production + scanning workstation represented a third goal of CXP; to date, 1,000 + volumes have been scanned, or about 300,000 images. + + * The resulting digital files are stored and used to produce + hard-copy replacements for the originals and additional prints on + demand; although the initial costs are high, scanning technology + offers an affordable means for reformatting brittle material. + + * A technician in production mode can scan 300 pages per hour when + performing single-sheet scanning, which is a necessity when working + with truly brittle paper; this figure is expected to increase + significantly with subsequent iterations of the software from Xerox; + a three-month time-and-cost study of scanning found that the average + 300-page book would take about an hour and forty minutes to scan + (this figure included the time for setup, which involves keying in + primary bibliographic data, going into quality control mode to + define page size, establishing front-to-back registration, and + scanning sample pages to identify a default range of settings for + the entire book--functions not dissimilar to those performed by + filmers or those preparing a book for photocopy). + + * The final step in the scanning process involved rescans, which + happily were few and far between, representing well under 1 percent + of the total pages scanned. + +In addition to technician time, CXP costed out equipment, amortized over +four years, the cost of storing and refreshing the digital files every +four years, and the cost of printing and binding, book-cloth binding, a +paper reproduction. The total amounted to a little under $65 per single +300-page volume, with 30 percent overhead included--a figure competitive +with the prices currently charged by photocopy vendors. + +Of course, with scanning, in addition to the paper facsimile, one is left +with a digital file from which subsequent copies of the book can be +produced for a fraction of the cost of photocopy, with readers afforded +choices in the form of these copies. + +KENNEY concluded that digital technology offers an electronic means for a +library preservation effort to pay for itself. If a brittle-book program +included the means of disseminating reprints of books that are in demand +by libraries and researchers alike, the initial investment in capture +could be recovered and used to preserve additional but less popular +books. She disclosed that an economic model for a self-sustaining +program could be developed for CXP's report to the Commission on +Preservation and Access (CPA). + +KENNEY stressed that the focus of CXP has been on obtaining high quality +in a production environment. The use of digital technology is viewed as +an affordable alternative to other reformatting options. + + ****** + ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ +ANDRE * Overview and history of NATDP * Various agricultural CD-ROM +products created inhouse and by service bureaus * Pilot project on +Internet transmission * Additional products in progress * ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ + +Pamela ANDRE, associate director for automation, National Agricultural +Text Digitizing Program (NATDP), National Agricultural Library (NAL), +presented an overview of NATDP, which has been underway at NAL the last +four years, before Judith ZIDAR discussed the technical details. ANDRE +defined agricultural information as a broad range of material going from +basic and applied research in the hard sciences to the one-page pamphlets +that are distributed by the cooperative state extension services on such +things as how to grow blueberries. + +NATDP began in late 1986 with a meeting of representatives from the +land-grant library community to deal with the issue of electronic +information. NAL and forty-five of these libraries banded together to +establish this project--to evaluate the technology for converting what +were then source documents in paper form into electronic form, to provide +access to that digital information, and then to distribute it. +Distributing that material to the community--the university community as +well as the extension service community, potentially down to the county +level--constituted the group's chief concern. + +Since January 1988 (when the microcomputer-based scanning system was +installed at NAL), NATDP has done a variety of things, concerning which +ZIDAR would provide further details. For example, the first technology +considered in the project's discussion phase was digital videodisc, which +indicates how long ago it was conceived. + +Over the four years of this project, four separate CD-ROM products on +four different agricultural topics were created, two at a +scanning-and-OCR station installed at NAL, and two by service bureaus. +Thus, NATDP has gained comparative information in terms of those relative +costs. Each of these products contained the full ASCII text as well as +page images of the material, or between 4,000 and 6,000 pages of material +on these disks. Topics included aquaculture, food, agriculture and +science (i.e., international agriculture and research), acid rain, and +Agent Orange, which was the final product distributed (approximately +eighteen months before the Workshop). + +The third phase of NATDP focused on delivery mechanisms other than +CD-ROM. At the suggestion of Clifford LYNCH, who was a technical +consultant to the project at this point, NATDP became involved with the +Internet and initiated a project with the help of North Carolina State +University, in which fourteen of the land-grant university libraries are +transmitting digital images over the Internet in response to interlibrary +loan requests--a topic for another meeting. At this point, the pilot +project had been completed for about a year and the final report would be +available shortly after the Workshop. In the meantime, the project's +success had led to its extension. (ANDRE noted that one of the first +things done under the program title was to select a retrieval package to +use with subsequent products; Windows Personal Librarian was the package +of choice after a lengthy evaluation.) + +Three additional products had been planned and were in progress: + + 1) An arrangement with the American Society of Agronomy--a + professional society that has published the Agronomy Journal since + about 1908--to scan and create bit-mapped images of its journal. + ASA granted permission first to put and then to distribute this + material in electronic form, to hold it at NAL, and to use these + electronic images as a mechanism to deliver documents or print out + material for patrons, among other uses. Effectively, NAL has the + right to use this material in support of its program. + (Significantly, this arrangement offers a potential cooperative + model for working with other professional societies in agriculture + to try to do the same thing--put the journals of particular interest + to agriculture research into electronic form.) + + 2) An extension of the earlier product on aquaculture. + + 3) The George Washington Carver Papers--a joint project with + Tuskegee University to scan and convert from microfilm some 3,500 + images of Carver's papers, letters, and drawings. + +It was anticipated that all of these products would appear no more than +six months after the Workshop. + + ****** + ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ +ZIDAR * (A separate arena for scanning) * Steps in creating a database * +Image capture, with and without performing OCR * Keying in tracking data +* Scanning, with electronic and manual tracking * Adjustments during +scanning process * Scanning resolutions * Compression * De-skewing and +filtering * Image capture from microform: the papers and letters of +George Washington Carver * Equipment used for a scanning system * ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ + +Judith ZIDAR, coordinator, National Agricultural Text Digitizing Program +(NATDP), National Agricultural Library (NAL), illustrated the technical +details of NATDP, including her primary responsibility, scanning and +creating databases on a topic and putting them on CD-ROM. + +(ZIDAR remarked a separate arena from the CD-ROM projects, although the +processing of the material is nearly identical, in which NATDP is also +scanning material and loading it on a Next microcomputer, which in turn +is linked to NAL's integrated library system. Thus, searches in NAL's +bibliographic database will enable people to pull up actual page images +and text for any documents that have been entered.) + +In accordance with the session's topic, ZIDAR focused her illustrated +talk on image capture, offering a primer on the three main steps in the +process: 1) assemble the printed publications; 2) design the database +(database design occurs in the process of preparing the material for +scanning; this step entails reviewing and organizing the material, +defining the contents--what will constitute a record, what kinds of +fields will be captured in terms of author, title, etc.); 3) perform a +certain amount of markup on the paper publications. NAL performs this +task record by record, preparing work sheets or some other sort of +tracking material and designing descriptors and other enhancements to be +added to the data that will not be captured from the printed publication. +Part of this process also involves determining NATDP's file and directory +structure: NATDP attempts to avoid putting more than approximately 100 +images in a directory, because placing more than that on a CD-ROM would +reduce the access speed. + +This up-front process takes approximately two weeks for a +6,000-7,000-page database. The next step is to capture the page images. +How long this process takes is determined by the decision whether or not +to perform OCR. Not performing OCR speeds the process, whereas text +capture requires greater care because of the quality of the image: it +has to be straighter and allowance must be made for text on a page, not +just for the capture of photographs. + +NATDP keys in tracking data, that is, a standard bibliographic record +including the title of the book and the title of the chapter, which will +later either become the access information or will be attached to the +front of a full-text record so that it is searchable. + +Images are scanned from a bound or unbound publication, chiefly from +bound publications in the case of NATDP, however, because often they are +the only copies and the publications are returned to the shelves. NATDP +usually scans one record at a time, because its database tracking system +tracks the document in that way and does not require further logical +separating of the images. After performing optical character +recognition, NATDP moves the images off the hard disk and maintains a +volume sheet. Though the system tracks electronically, all the +processing steps are also tracked manually with a log sheet. + +ZIDAR next illustrated the kinds of adjustments that one can make when +scanning from paper and microfilm, for example, redoing images that need +special handling, setting for dithering or gray scale, and adjusting for +brightness or for the whole book at one time. + +NATDP is scanning at 300 dots per inch, a standard scanning resolution. +Though adequate for capturing text that is all of a standard size, 300 +dpi is unsuitable for any kind of photographic material or for very small +text. Many scanners allow for different image formats, TIFF, of course, +being a de facto standard. But if one intends to exchange images with +other people, the ability to scan other image formats, even if they are +less common, becomes highly desirable. + +CCITT Group 4 is the standard compression for normal black-and-white +images, JPEG for gray scale or color. ZIDAR recommended 1) using the +standard compressions, particularly if one attempts to make material +available and to allow users to download images and reuse them from +CD-ROMs; and 2) maintaining the ability to output an uncompressed image, +because in image exchange uncompressed images are more likely to be able +to cross platforms. + +ZIDAR emphasized the importance of de-skewing and filtering as +requirements on NATDP's upgraded system. For instance, scanning bound +books, particularly books published by the federal government whose pages +are skewed, and trying to scan them straight if OCR is to be performed, +is extremely time-consuming. The same holds for filtering of +poor-quality or older materials. + +ZIDAR described image capture from microform, using as an example three +reels from a sixty-seven-reel set of the papers and letters of George +Washington Carver that had been produced by Tuskegee University. These +resulted in approximately 3,500 images, which NATDP had had scanned by +its service contractor, Science Applications International Corporation +(SAIC). NATDP also created bibliographic records for access. (NATDP did +not have such specialized equipment as a microfilm scanner. + +Unfortunately, the process of scanning from microfilm was not an +unqualified success, ZIDAR reported: because microfilm frame sizes vary, +occasionally some frames were missed, which without spending much time +and money could not be recaptured. + +OCR could not be performed from the scanned images of the frames. The +bleeding in the text simply output text, when OCR was run, that could not +even be edited. NATDP tested for negative versus positive images, +landscape versus portrait orientation, and single- versus dual-page +microfilm, none of which seemed to affect the quality of the image; but +also on none of them could OCR be performed. + +In selecting the microfilm they would use, therefore, NATDP had other +factors in mind. ZIDAR noted two factors that influenced the quality of +the images: 1) the inherent quality of the original and 2) the amount of +size reduction on the pages. + +The Carver papers were selected because they are informative and visually +interesting, treat a single subject, and are valuable in their own right. +The images were scanned and divided into logical records by SAIC, then +delivered, and loaded onto NATDP's system, where bibliographic +information taken directly from the images was added. Scanning was +completed in summer 1991 and by the end of summer 1992 the disk was +scheduled to be published. + +Problems encountered during processing included the following: Because +the microfilm scanning had to be done in a batch, adjustment for +individual page variations was not possible. The frame size varied on +account of the nature of the material, and therefore some of the frames +were missed while others were just partial frames. The only way to go +back and capture this material was to print out the page with the +microfilm reader from the missing frame and then scan it in from the +page, which was extremely time-consuming. The quality of the images +scanned from the printout of the microfilm compared unfavorably with that +of the original images captured directly from the microfilm. The +inability to perform OCR also was a major disappointment. At the time, +computer output microfilm was unavailable to test. + +The equipment used for a scanning system was the last topic addressed by +ZIDAR. The type of equipment that one would purchase for a scanning +system included: a microcomputer, at least a 386, but preferably a 486; +a large hard disk, 380 megabyte at minimum; a multi-tasking operating +system that allows one to run some things in batch in the background +while scanning or doing text editing, for example, Unix or OS/2 and, +theoretically, Windows; a high-speed scanner and scanning software that +allows one to make the various adjustments mentioned earlier; a +high-resolution monitor (150 dpi ); OCR software and hardware to perform +text recognition; an optical disk subsystem on which to archive all the +images as the processing is done; file management and tracking software. + +ZIDAR opined that the software one purchases was more important than the +hardware and might also cost more than the hardware, but it was likely to +prove critical to the success or failure of one's system. In addition to +a stand-alone scanning workstation for image capture, then, text capture +requires one or two editing stations networked to this scanning station +to perform editing. Editing the text takes two or three times as long as +capturing the images. + +Finally, ZIDAR stressed the importance of buying an open system that allows +for more than one vendor, complies with standards, and can be upgraded. + + ****** + ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ +WATERS *Yale University Library's master plan to convert microfilm to +digital imagery (POB) * The place of electronic tools in the library of +the future * The uses of images and an image library * Primary input from +preservation microfilm * Features distinguishing POB from CXP and key +hypotheses guiding POB * Use of vendor selection process to facilitate +organizational work * Criteria for selecting vendor * Finalists and +results of process for Yale * Key factor distinguishing vendors * +Components, design principles, and some estimated costs of POB * Role of +preservation materials in developing imaging market * Factors affecting +quality and cost * Factors affecting the usability of complex documents +in image form * ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ + +Donald WATERS, head of the Systems Office, Yale University Library, +reported on the progress of a master plan for a project at Yale to +convert microfilm to digital imagery, Project Open Book (POB). Stating +that POB was in an advanced stage of planning, WATERS detailed, in +particular, the process of selecting a vendor partner and several key +issues under discussion as Yale prepares to move into the project itself. +He commented first on the vision that serves as the context of POB and +then described its purpose and scope. + +WATERS sees the library of the future not necessarily as an electronic +library but as a place that generates, preserves, and improves for its +clients ready access to both intellectual and physical recorded +knowledge. Electronic tools must find a place in the library in the +context of this vision. Several roles for electronic tools include +serving as: indirect sources of electronic knowledge or as "finding" +aids (the on-line catalogues, the article-level indices, registers for +documents and archives); direct sources of recorded knowledge; full-text +images; and various kinds of compound sources of recorded knowledge (the +so-called compound documents of Hypertext, mixed text and image, +mixed-text image format, and multimedia). + +POB is looking particularly at images and an image library, the uses to +which images will be put (e.g., storage, printing, browsing, and then use +as input for other processes), OCR as a subsequent process to image +capture, or creating an image library, and also possibly generating +microfilm. + +While input will come from a variety of sources, POB is considering +especially input from preservation microfilm. A possible outcome is that +the film and paper which provide the input for the image library +eventually may go off into remote storage, and that the image library may +be the primary access tool. + +The purpose and scope of POB focus on imaging. Though related to CXP, +POB has two features which distinguish it: 1) scale--conversion of +10,000 volumes into digital image form; and 2) source--conversion from +microfilm. Given these features, several key working hypotheses guide +POB, including: 1) Since POB is using microfilm, it is not concerned with +the image library as a preservation medium. 2) Digital imagery can improve +access to recorded knowledge through printing and network distribution at +a modest incremental cost of microfilm. 3) Capturing and storing documents +in a digital image form is necessary to further improvements in access. +(POB distinguishes between the imaging, digitizing process and OCR, +which at this stage it does not plan to perform.) + +Currently in its first or organizational phase, POB found that it could +use a vendor selection process to facilitate a good deal of the +organizational work (e.g., creating a project team and advisory board, +confirming the validity of the plan, establishing the cost of the project +and a budget, selecting the materials to convert, and then raising the +necessary funds). + +POB developed numerous selection criteria, including: a firm committed +to image-document management, the ability to serve as systems integrator +in a large-scale project over several years, interest in developing the +requisite software as a standard rather than a custom product, and a +willingness to invest substantial resources in the project itself. + +Two vendors, DEC and Xerox, were selected as finalists in October 1991, +and with the support of the Commission on Preservation and Access, each +was commissioned to generate a detailed requirements analysis for the +project and then to submit a formal proposal for the completion of the +project, which included a budget and costs. The terms were that POB would +pay the loser. The results for Yale of involving a vendor included: +broad involvement of Yale staff across the board at a relatively low +cost, which may have long-term significance in carrying out the project +(twenty-five to thirty university people are engaged in POB); better +understanding of the factors that affect corporate response to markets +for imaging products; a competitive proposal; and a more sophisticated +view of the imaging markets. + +The most important factor that distinguished the vendors under +consideration was their identification with the customer. The size and +internal complexity of the company also was an important factor. POB was +looking at large companies that had substantial resources. In the end, +the process generated for Yale two competitive proposals, with Xerox's +the clear winner. WATERS then described the components of the proposal, +the design principles, and some of the costs estimated for the process. + +Components are essentially four: a conversion subsystem, a +network-accessible storage subsystem for 10,000 books (and POB expects +200 to 600 dpi storage), browsing stations distributed on the campus +network, and network access to the image printers. + +Among the design principles, POB wanted conversion at the highest +possible resolution. Assuming TIFF files, TIFF files with Group 4 +compression, TCP/IP, and ethernet network on campus, POB wanted a +client-server approach with image documents distributed to the +workstations and made accessible through native workstation interfaces +such as Windows. POB also insisted on a phased approach to +implementation: 1) a stand-alone, single-user, low-cost entry into the +business with a workstation focused on conversion and allowing POB to +explore user access; 2) movement into a higher-volume conversion with +network-accessible storage and multiple access stations; and 3) a +high-volume conversion, full-capacity storage, and multiple browsing +stations distributed throughout the campus. + +The costs proposed for start-up assumed the existence of the Yale network +and its two DocuTech image printers. Other start-up costs are estimated +at $1 million over the three phases. At the end of the project, the annual +operating costs estimated primarily for the software and hardware proposed +come to about $60,000, but these exclude costs for labor needed in the +conversion process, network and printer usage, and facilities management. + +Finally, the selection process produced for Yale a more sophisticated +view of the imaging markets: the management of complex documents in +image form is not a preservation problem, not a library problem, but a +general problem in a broad, general industry. Preservation materials are +useful for developing that market because of the qualities of the +material. For example, much of it is out of copyright. The resolution +of key issues such as the quality of scanning and image browsing also +will affect development of that market. + +The technology is readily available but changing rapidly. In this +context of rapid change, several factors affect quality and cost, to +which POB intends to pay particular attention, for example, the various +levels of resolution that can be achieved. POB believes it can bring +resolution up to 600 dpi, but an interpolation process from 400 to 600 is +more likely. The variation quality in microfilm will prove to be a +highly important factor. POB may reexamine the standards used to film in +the first place by looking at this process as a follow-on to microfilming. + +Other important factors include: the techniques available to the +operator for handling material, the ways of integrating quality control +into the digitizing work flow, and a work flow that includes indexing and +storage. POB's requirement was to be able to deal with quality control +at the point of scanning. Thus, thanks to Xerox, POB anticipates having +a mechanism which will allow it not only to scan in batch form, but to +review the material as it goes through the scanner and control quality +from the outset. + +The standards for measuring quality and costs depend greatly on the uses +of the material, including subsequent OCR, storage, printing, and +browsing. But especially at issue for POB is the facility for browsing. +This facility, WATERS said, is perhaps the weakest aspect of imaging +technology and the most in need of development. + +A variety of factors affect the usability of complex documents in image +form, among them: 1) the ability of the system to handle the full range +of document types, not just monographs but serials, multi-part +monographs, and manuscripts; 2) the location of the database of record +for bibliographic information about the image document, which POB wants +to enter once and in the most useful place, the on-line catalog; 3) a +document identifier for referencing the bibliographic information in one +place and the images in another; 4) the technique for making the basic +internal structure of the document accessible to the reader; and finally, +5) the physical presentation on the CRT of those documents. POB is ready +to complete this phase now. One last decision involves deciding which +material to scan. + + ****** + ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ +DISCUSSION * TIFF files constitute de facto standard * NARA's experience +with image conversion software and text conversion * RFC 1314 * +Considerable flux concerning available hardware and software solutions * +NAL through-put rate during scanning * Window management questions * ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ + +In the question-and-answer period that followed WATERS's presentation, +the following points emerged: + + * ZIDAR's statement about using TIFF files as a standard meant de + facto standard. This is what most people use and typically exchange + with other groups, across platforms, or even occasionally across + display software. + + * HOLMES commented on the unsuccessful experience of NARA in + attempting to run image-conversion software or to exchange between + applications: What are supposedly TIFF files go into other software + that is supposed to be able to accept TIFF but cannot recognize the + format and cannot deal with it, and thus renders the exchange + useless. Re text conversion, he noted the different recognition + rates obtained by substituting the make and model of scanners in + NARA's recent test of an "intelligent" character-recognition product + for a new company. In the selection of hardware and software, + HOLMES argued, software no longer constitutes the overriding factor + it did until about a year ago; rather it is perhaps important to + look at both now. + + * Danny Cohen and Alan Katz of the University of Southern California + Information Sciences Institute began circulating as an Internet RFC + (RFC 1314) about a month ago a standard for a TIFF interchange + format for Internet distribution of monochrome bit-mapped images, + which LYNCH said he believed would be used as a de facto standard. + + * FLEISCHHAUER's impression from hearing these reports and thinking + about AM's experience was that there is considerable flux concerning + available hardware and software solutions. HOOTON agreed and + commented at the same time on ZIDAR's statement that the equipment + employed affects the results produced. One cannot draw a complete + conclusion by saying it is difficult or impossible to perform OCR + from scanning microfilm, for example, with that device, that set of + parameters, and system requirements, because numerous other people + are accomplishing just that, using other components, perhaps. + HOOTON opined that both the hardware and the software were highly + important. Most of the problems discussed today have been solved in + numerous different ways by other people. Though it is good to be + cognizant of various experiences, this is not to say that it will + always be thus. + + * At NAL, the through-put rate of the scanning process for paper, + page by page, performing OCR, ranges from 300 to 600 pages per day; + not performing OCR is considerably faster, although how much faster + is not known. This is for scanning from bound books, which is much + slower. + + * WATERS commented on window management questions: DEC proposed an + X-Windows solution which was problematical for two reasons. One was + POB's requirement to be able to manipulate images on the workstation + and bring them down to the workstation itself and the other was + network usage. + + ****** + ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ +THOMA * Illustration of deficiencies in scanning and storage process * +Image quality in this process * Different costs entailed by better image +quality * Techniques for overcoming various de-ficiencies: fixed +thresholding, dynamic thresholding, dithering, image merge * Page edge +effects * ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ + +George THOMA, chief, Communications Engineering Branch, National Library +of Medicine (NLM), illustrated several of the deficiencies discussed by +the previous speakers. He introduced the topic of special problems by +noting the advantages of electronic imaging. For example, it is regenerable +because it is a coded file, and real-time quality control is possible with +electronic capture, whereas in photographic capture it is not. + +One of the difficulties discussed in the scanning and storage process was +image quality which, without belaboring the obvious, means different +things for maps, medical X-rays, or broadcast television. In the case of +documents, THOMA said, image quality boils down to legibility of the +textual parts, and fidelity in the case of gray or color photo print-type +material. Legibility boils down to scan density, the standard in most +cases being 300 dpi. Increasing the resolution with scanners that +perform 600 or 1200 dpi, however, comes at a cost. + +Better image quality entails at least four different kinds of costs: 1) +equipment costs, because the CCD (i.e., charge-couple device) with +greater number of elements costs more; 2) time costs that translate to +the actual capture costs, because manual labor is involved (the time is +also dependent on the fact that more data has to be moved around in the +machine in the scanning or network devices that perform the scanning as +well as the storage); 3) media costs, because at high resolutions larger +files have to be stored; and 4) transmission costs, because there is just +more data to be transmitted. + +But while resolution takes care of the issue of legibility in image +quality, other deficiencies have to do with contrast and elements on the +page scanned or the image that needed to be removed or clarified. Thus, +THOMA proceeded to illustrate various deficiencies, how they are +manifested, and several techniques to overcome them. + +Fixed thresholding was the first technique described, suitable for +black-and-white text, when the contrast does not vary over the page. One +can have many different threshold levels in scanning devices. Thus, +THOMA offered an example of extremely poor contrast, which resulted from +the fact that the stock was a heavy red. This is the sort of image that +when microfilmed fails to provide any legibility whatsoever. Fixed +thresholding is the way to change the black-to-red contrast to the +desired black-to-white contrast. + +Other examples included material that had been browned or yellowed by +age. This was also a case of contrast deficiency, and correction was +done by fixed thresholding. A final example boils down to the same +thing, slight variability, but it is not significant. Fixed thresholding +solves this problem as well. The microfilm equivalent is certainly legible, +but it comes with dark areas. Though THOMA did not have a slide of the +microfilm in this case, he did show the reproduced electronic image. + +When one has variable contrast over a page or the lighting over the page +area varies, especially in the case where a bound volume has light +shining on it, the image must be processed by a dynamic thresholding +scheme. One scheme, dynamic averaging, allows the threshold level not to +be fixed but to be recomputed for every pixel from the neighboring +characteristics. The neighbors of a pixel determine where the threshold +should be set for that pixel. + +THOMA showed an example of a page that had been made deficient by a +variety of techniques, including a burn mark, coffee stains, and a yellow +marker. Application of a fixed-thresholding scheme, THOMA argued, might +take care of several deficiencies on the page but not all of them. +Performing the calculation for a dynamic threshold setting, however, +removes most of the deficiencies so that at least the text is legible. + +Another problem is representing a gray level with black-and-white pixels +by a process known as dithering or electronic screening. But dithering +does not provide good image quality for pure black-and-white textual +material. THOMA illustrated this point with examples. Although its +suitability for photoprint is the reason for electronic screening or +dithering, it cannot be used for every compound image. In the document +that was distributed by CXP, THOMA noticed that the dithered image of the +IEEE test chart evinced some deterioration in the text. He presented an +extreme example of deterioration in the text in which compounded +documents had to be set right by other techniques. The technique +illustrated by the present example was an image merge in which the page +is scanned twice and the settings go from fixed threshold to the +dithering matrix; the resulting images are merged to give the best +results with each technique. + +THOMA illustrated how dithering is also used in nonphotographic or +nonprint materials with an example of a grayish page from a medical text, +which was reproduced to show all of the gray that appeared in the +original. Dithering provided a reproduction of all the gray in the +original of another example from the same text. + +THOMA finally illustrated the problem of bordering, or page-edge, +effects. Books and bound volumes that are placed on a photocopy machine +or a scanner produce page-edge effects that are undesirable for two +reasons: 1) the aesthetics of the image; after all, if the image is to +be preserved, one does not necessarily want to keep all of its +deficiencies; 2) compression (with the bordering problem THOMA +illustrated, the compression ratio deteriorated tremendously). One way +to eliminate this more serious problem is to have the operator at the +point of scanning window the part of the image that is desirable and +automatically turn all of the pixels out of that picture to white. + + ****** + ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ +FLEISCHHAUER * AM's experience with scanning bound materials * Dithering +* ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ + +Carl FLEISCHHAUER, coordinator, American Memory, Library of Congress, +reported AM's experience with scanning bound materials, which he likened +to the problems involved in using photocopying machines. Very few +devices in the industry offer book-edge scanning, let alone book cradles. +The problem may be unsolvable, FLEISCHHAUER said, because a large enough +market does not exist for a preservation-quality scanner. AM is using a +Kurzweil scanner, which is a book-edge scanner now sold by Xerox. + +Devoting the remainder of his brief presentation to dithering, +FLEISCHHAUER related AM's experience with a contractor who was using +unsophisticated equipment and software to reduce moire patterns from +printed halftones. AM took the same image and used the dithering +algorithm that forms part of the same Kurzweil Xerox scanner; it +disguised moire patterns much more effectively. + +FLEISCHHAUER also observed that dithering produces a binary file which is +useful for numerous purposes, for example, printing it on a laser printer +without having to "re-halftone" it. But it tends to defeat efficient +compression, because the very thing that dithers to reduce moire patterns +also tends to work against compression schemes. AM thought the +difference in image quality was worth it. + + ****** + ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ +DISCUSSION * Relative use as a criterion for POB's selection of books to +be converted into digital form * ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ + +During the discussion period, WATERS noted that one of the criteria for +selecting books among the 10,000 to be converted into digital image form +would be how much relative use they would receive--a subject still +requiring evaluation. The challenge will be to understand whether +coherent bodies of material will increase usage or whether POB should +seek material that is being used, scan that, and make it more accessible. +POB might decide to digitize materials that are already heavily used, in +order to make them more accessible and decrease wear on them. Another +approach would be to provide a large body of intellectually coherent +material that may be used more in digital form than it is currently used +in microfilm. POB would seek material that was out of copyright. + + ****** + ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ +BARONAS * Origin and scope of AIIM * Types of documents produced in +AIIM's standards program * Domain of AIIM's standardization work * AIIM's +structure * TC 171 and MS23 * Electronic image management standards * +Categories of EIM standardization where AIIM standards are being +developed * ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ + +Jean BARONAS, senior manager, Department of Standards and Technology, +Association for Information and Image Management (AIIM), described the +not-for-profit association and the national and international programs +for standardization in which AIIM is active. + +Accredited for twenty-five years as the nation's standards development +organization for document image management, AIIM began life in a library +community developing microfilm standards. Today the association +maintains both its library and business-image management standardization +activities--and has moved into electronic image-management +standardization (EIM). + +BARONAS defined the program's scope. AIIM deals with: 1) the +terminology of standards and of the technology it uses; 2) methods of +measurement for the systems, as well as quality; 3) methodologies for +users to evaluate and measure quality; 4) the features of apparatus used +to manage and edit images; and 5) the procedures used to manage images. + +BARONAS noted that three types of documents are produced in the AIIM +standards program: the first two, accredited by the American National +Standards Institute (ANSI), are standards and standard recommended +practices. Recommended practices differ from standards in that they +contain more tutorial information. A technical report is not an ANSI +standard. Because AIIM's policies and procedures for developing +standards are approved by ANSI, its standards are labeled ANSI/AIIM, +followed by the number and title of the standard. + +BARONAS then illustrated the domain of AIIM's standardization work. For +example, AIIM is the administrator of the U.S. Technical Advisory Group +(TAG) to the International Standards Organization's (ISO) technical +committee, TC l7l Micrographics and Optical Memories for Document and +Image Recording, Storage, and Use. AIIM officially works through ANSI in +the international standardization process. + +BARONAS described AIIM's structure, including its board of directors, its +standards board of twelve individuals active in the image-management +industry, its strategic planning and legal admissibility task forces, and +its National Standards Council, which is comprised of the members of a +number of organizations who vote on every AIIM standard before it is +published. BARONAS pointed out that AIIM's liaisons deal with numerous +other standards developers, including the optical disk community, office +and publishing systems, image-codes-and-character set committees, and the +National Information Standards Organization (NISO). + +BARONAS illustrated the procedures of TC l7l, which covers all aspects of +image management. When AIIM's national program has conceptualized a new +project, it is usually submitted to the international level, so that the +member countries of TC l7l can simultaneously work on the development of +the standard or the technical report. BARONAS also illustrated a classic +microfilm standard, MS23, which deals with numerous imaging concepts that +apply to electronic imaging. Originally developed in the l970s, revised +in the l980s, and revised again in l991, this standard is scheduled for +another revision. MS23 is an active standard whereby users may propose +new density ranges and new methods of evaluating film images in the +standard's revision. + +BARONAS detailed several electronic image-management standards, for +instance, ANSI/AIIM MS44, a quality-control guideline for scanning 8.5" +by 11" black-and-white office documents. This standard is used with the +IEEE fax image--a continuous tone photographic image with gray scales, +text, and several continuous tone pictures--and AIIM test target number +2, a representative document used in office document management. + +BARONAS next outlined the four categories of EIM standardization in which +AIIM standards are being developed: transfer and retrieval, evaluation, +optical disc and document scanning applications, and design and +conversion of documents. She detailed several of the main projects of +each: 1) in the category of image transfer and retrieval, a bi-level +image transfer format, ANSI/AIIM MS53, which is a proposed standard that +describes a file header for image transfer between unlike systems when +the images are compressed using G3 and G4 compression; 2) the category of +image evaluation, which includes the AIIM-proposed TR26 tutorial on image +resolution (this technical report will treat the differences and +similarities between classical or photographic and electronic imaging); +3) design and conversion, which includes a proposed technical report +called "Forms Design Optimization for EIM" (this report considers how +general-purpose business forms can be best designed so that scanning is +optimized; reprographic characteristics such as type, rules, background, +tint, and color will likewise be treated in the technical report); 4) +disk and document scanning applications includes a project a) on planning +platters and disk management, b) on generating an application profile for +EIM when images are stored and distributed on CD-ROM, and c) on +evaluating SCSI2, and how a common command set can be generated for SCSI2 +so that document scanners are more easily integrated. (ANSI/AIIM MS53 +will also apply to compressed images.) + + ****** + ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ +BATTIN * The implications of standards for preservation * A major +obstacle to successful cooperation * A hindrance to access in the digital +environment * Standards a double-edged sword for those concerned with the +preservation of the human record * Near-term prognosis for reliable +archival standards * Preservation concerns for electronic media * Need +for reconceptualizing our preservation principles * Standards in the real +world and the politics of reproduction * Need to redefine the concept of +archival and to begin to think in terms of life cycles * Cooperation and +the La Guardia Eight * Concerns generated by discussions on the problems +of preserving text and image * General principles to be adopted in a +world without standards * ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ + +Patricia BATTIN, president, the Commission on Preservation and Access +(CPA), addressed the implications of standards for preservation. She +listed several areas where the library profession and the analog world of +the printed book had made enormous contributions over the past hundred +years--for example, in bibliographic formats, binding standards, and, most +important, in determining what constitutes longevity or archival quality. + +Although standards have lightened the preservation burden through the +development of national and international collaborative programs, +nevertheless, a pervasive mistrust of other people's standards remains a +major obstacle to successful cooperation, BATTIN said. + +The zeal to achieve perfection, regardless of the cost, has hindered +rather than facilitated access in some instances, and in the digital +environment, where no real standards exist, has brought an ironically +just reward. + +BATTIN argued that standards are a double-edged sword for those concerned +with the preservation of the human record, that is, the provision of +access to recorded knowledge in a multitude of media as far into the +future as possible. Standards are essential to facilitate +interconnectivity and access, but, BATTIN said, as LYNCH pointed out +yesterday, if set too soon they can hinder creativity, expansion of +capability, and the broadening of access. The characteristics of +standards for digital imagery differ radically from those for analog +imagery. And the nature of digital technology implies continuing +volatility and change. To reiterate, precipitous standard-setting can +inhibit creativity, but delayed standard-setting results in chaos. + +Since in BATTIN'S opinion the near-term prognosis for reliable archival +standards, as defined by librarians in the analog world, is poor, two +alternatives remain: standing pat with the old technology, or +reconceptualizing. + +Preservation concerns for electronic media fall into two general domains. +One is the continuing assurance of access to knowledge originally +generated, stored, disseminated, and used in electronic form. This +domain contains several subdivisions, including 1) the closed, +proprietary systems discussed the previous day, bundled information such +as electronic journals and government agency records, and electronically +produced or captured raw data; and 2) the application of digital +technologies to the reformatting of materials originally published on a +deteriorating analog medium such as acid paper or videotape. + +The preservation of electronic media requires a reconceptualizing of our +preservation principles during a volatile, standardless transition which +may last far longer than any of us envision today. BATTIN urged the +necessity of shifting focus from assessing, measuring, and setting +standards for the permanence of the medium to the concept of managing +continuing access to information stored on a variety of media and +requiring a variety of ever-changing hardware and software for access--a +fundamental shift for the library profession. + +BATTIN offered a primer on how to move forward with reasonable confidence +in a world without standards. Her comments fell roughly into two sections: +1) standards in the real world and 2) the politics of reproduction. + +In regard to real-world standards, BATTIN argued the need to redefine the +concept of archive and to begin to think in terms of life cycles. In +the past, the naive assumption that paper would last forever produced a +cavalier attitude toward life cycles. The transient nature of the +electronic media has compelled people to recognize and accept upfront the +concept of life cycles in place of permanency. + +Digital standards have to be developed and set in a cooperative context +to ensure efficient exchange of information. Moreover, during this +transition period, greater flexibility concerning how concepts such as +backup copies and archival copies in the CXP are defined is necessary, +or the opportunity to move forward will be lost. + +In terms of cooperation, particularly in the university setting, BATTIN +also argued the need to avoid going off in a hundred different +directions. The CPA has catalyzed a small group of universities called +the La Guardia Eight--because La Guardia Airport is where meetings take +place--Harvard, Yale, Cornell, Princeton, Penn State, Tennessee, +Stanford, and USC, to develop a digital preservation consortium to look +at all these issues and develop de facto standards as we move along, +instead of waiting for something that is officially blessed. Continuing +to apply analog values and definitions of standards to the digital +environment, BATTIN said, will effectively lead to forfeiture of the +benefits of digital technology to research and scholarship. + +Under the second rubric, the politics of reproduction, BATTIN reiterated +an oft-made argument concerning the electronic library, namely, that it +is more difficult to transform than to create, and nowhere is that belief +expressed more dramatically than in the conversion of brittle books to +new media. Preserving information published in electronic media involves +making sure the information remains accessible and that digital +information is not lost through reproduction. In the analog world of +photocopies and microfilm, the issue of fidelity to the original becomes +paramount, as do issues of "Whose fidelity?" and "Whose original?" + +BATTIN elaborated these arguments with a few examples from a recent study +conducted by the CPA on the problems of preserving text and image. +Discussions with scholars, librarians, and curators in a variety of +disciplines dependent on text and image generated a variety of concerns, +for example: 1) Copy what is, not what the technology is capable of. +This is very important for the history of ideas. Scholars wish to know +what the author saw and worked from. And make available at the +workstation the opportunity to erase all the defects and enhance the +presentation. 2) The fidelity of reproduction--what is good enough, what +can we afford, and the difference it makes--issues of subjective versus +objective resolution. 3) The differences between primary and secondary +users. Restricting the definition of primary user to the one in whose +discipline the material has been published runs one headlong into the +reality that these printed books have had a host of other users from a +host of other disciplines, who not only were looking for very different +things, but who also shared values very different from those of the +primary user. 4) The relationship of the standard of reproduction to new +capabilities of scholarship--the browsing standard versus an archival +standard. How good must the archival standard be? Can a distinction be +drawn between potential users in setting standards for reproduction? +Archival storage, use copies, browsing copies--ought an attempt to set +standards even be made? 5) Finally, costs. How much are we prepared to +pay to capture absolute fidelity? What are the trade-offs between vastly +enhanced access, degrees of fidelity, and costs? + +These standards, BATTIN concluded, serve to complicate further the +reproduction process, and add to the long list of technical standards +that are necessary to ensure widespread access. Ways to articulate and +analyze the costs that are attached to the different levels of standards +must be found. + +Given the chaos concerning standards, which promises to linger for the +foreseeable future, BATTIN urged adoption of the following general +principles: + + * Strive to understand the changing information requirements of + scholarly disciplines as more and more technology is integrated into + the process of research and scholarly communication in order to meet + future scholarly needs, not to build for the past. Capture + deteriorating information at the highest affordable resolution, even + though the dissemination and display technologies will lag. + + * Develop cooperative mechanisms to foster agreement on protocols + for document structure and other interchange mechanisms necessary + for widespread dissemination and use before official standards are + set. + + * Accept that, in a transition period, de facto standards will have + to be developed. + + * Capture information in a way that keeps all options open and + provides for total convertibility: OCR, scanning of microfilm, + producing microfilm from scanned documents, etc. + + * Work closely with the generators of information and the builders + of networks and databases to ensure that continuing accessibility is + a primary concern from the beginning. + + * Piggyback on standards under development for the broad market, and + avoid library-specific standards; work with the vendors, in order to + take advantage of that which is being standardized for the rest of + the world. + + * Concentrate efforts on managing permanence in the digital world, + rather than perfecting the longevity of a particular medium. + + ****** + ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ +DISCUSSION * Additional comments on TIFF * ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ + +During the brief discussion period that followed BATTIN's presentation, +BARONAS explained that TIFF was not developed in collaboration with or +under the auspices of AIIM. TIFF is a company product, not a standard, +is owned by two corporations, and is always changing. BARONAS also +observed that ANSI/AIIM MS53, a bi-level image file transfer format that +allows unlike systems to exchange images, is compatible with TIFF as well +as with DEC's architecture and IBM's MODCA/IOCA. + + ****** + ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ +HOOTON * Several questions to be considered in discussing text conversion +* ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ + +HOOTON introduced the final topic, text conversion, by noting that it is +becoming an increasingly important part of the imaging business. Many +people now realize that it enhances their system to be able to have more +and more character data as part of their imaging system. Re the issue of +OCR versus rekeying, HOOTON posed several questions: How does one get +text into computer-readable form? Does one use automated processes? +Does one attempt to eliminate the use of operators where possible? +Standards for accuracy, he said, are extremely important: it makes a +major difference in cost and time whether one sets as a standard 98.5 +percent acceptance or 99.5 percent. He mentioned outsourcing as a +possibility for converting text. Finally, what one does with the image +to prepare it for the recognition process is also important, he said, +because such preparation changes how recognition is viewed, as well as +facilitates recognition itself. + + ****** + ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ +LESK * Roles of participants in CORE * Data flow * The scanning process * +The image interface * Results of experiments involving the use of +electronic resources and traditional paper copies * Testing the issue of +serendipity * Conclusions * ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ + +Michael LESK, executive director, Computer Science Research, Bell +Communications Research, Inc. (Bellcore), discussed the Chemical Online +Retrieval Experiment (CORE), a cooperative project involving Cornell +University, OCLC, Bellcore, and the American Chemical Society (ACS). + +LESK spoke on 1) how the scanning was performed, including the unusual +feature of page segmentation, and 2) the use made of the text and the +image in experiments. + +Working with the chemistry journals (because ACS has been saving its +typesetting tapes since the mid-1970s and thus has a significant back-run +of the most important chemistry journals in the United States), CORE is +attempting to create an automated chemical library. Approximately a +quarter of the pages by square inch are made up of images of +quasi-pictorial material; dealing with the graphic components of the +pages is extremely important. LESK described the roles of participants +in CORE: 1) ACS provides copyright permission, journals on paper, +journals on microfilm, and some of the definitions of the files; 2) at +Bellcore, LESK chiefly performs the data preparation, while Dennis Egan +performs experiments on the users of chemical abstracts, and supplies the +indexing and numerous magnetic tapes; 3) Cornell provides the site of the +experiment; 4) OCLC develops retrieval software and other user interfaces. +Various manufacturers and publishers have furnished other help. + +Concerning data flow, Bellcore receives microfilm and paper from ACS; the +microfilm is scanned by outside vendors, while the paper is scanned +inhouse on an Improvision scanner, twenty pages per minute at 300 dpi, +which provides sufficient quality for all practical uses. LESK would +prefer to have more gray level, because one of the ACS journals prints on +some colored pages, which creates a problem. + +Bellcore performs all this scanning, creates a page-image file, and also +selects from the pages the graphics, to mix with the text file (which is +discussed later in the Workshop). The user is always searching the ASCII +file, but she or he may see a display based on the ASCII or a display +based on the images. + +LESK illustrated how the program performs page analysis, and the image +interface. (The user types several words, is presented with a list-- +usually of the titles of articles contained in an issue--that derives +from the ASCII, clicks on an icon and receives an image that mirrors an +ACS page.) LESK also illustrated an alternative interface, based on text +on the ASCII, the so-called SuperBook interface from Bellcore. + +LESK next presented the results of an experiment conducted by Dennis Egan +and involving thirty-six students at Cornell, one third of them +undergraduate chemistry majors, one third senior undergraduate chemistry +majors, and one third graduate chemistry students. A third of them +received the paper journals, the traditional paper copies and chemical +abstracts on paper. A third received image displays of the pictures of +the pages, and a third received the text display with pop-up graphics. + +The students were given several questions made up by some chemistry +professors. The questions fell into five classes, ranging from very easy +to very difficult, and included questions designed to simulate browsing +as well as a traditional information retrieval-type task. + +LESK furnished the following results. In the straightforward question +search--the question being, what is the phosphorus oxygen bond distance +and hydroxy phosphate?--the students were told that they could take +fifteen minutes and, then, if they wished, give up. The students with +paper took more than fifteen minutes on average, and yet most of them +gave up. The students with either electronic format, text or image, +received good scores in reasonable time, hardly ever had to give up, and +usually found the right answer. + +In the browsing study, the students were given a list of eight topics, +told to imagine that an issue of the Journal of the American Chemical +Society had just appeared on their desks, and were also told to flip +through it and to find topics mentioned in the issue. The average scores +were about the same. (The students were told to answer yes or no about +whether or not particular topics appeared.) The errors, however, were +quite different. The students with paper rarely said that something +appeared when it had not. But they often failed to find something +actually mentioned in the issue. The computer people found numerous +things, but they also frequently said that a topic was mentioned when it +was not. (The reason, of course, was that they were performing word +searches. They were finding that words were mentioned and they were +concluding that they had accomplished their task.) + +This question also contained a trick to test the issue of serendipity. +The students were given another list of eight topics and instructed, +without taking a second look at the journal, to recall how many of this +new list of eight topics were in this particular issue. This was an +attempt to see if they performed better at remembering what they were not +looking for. They all performed about the same, paper or electronics, +about 62 percent accurate. In short, LESK said, people were not very +good when it came to serendipity, but they were no worse at it with +computers than they were with paper. + +(LESK gave a parenthetical illustration of the learning curve of students +who used SuperBook.) + +The students using the electronic systems started off worse than the ones +using print, but by the third of the three sessions in the series had +caught up to print. As one might expect, electronics provide a much +better means of finding what one wants to read; reading speeds, once the +object of the search has been found, are about the same. + +Almost none of the students could perform the hard task--the analogous +transformation. (It would require the expertise of organic chemists to +complete.) But an interesting result was that the students using the text +search performed terribly, while those using the image system did best. +That the text search system is driven by text offers the explanation. +Everything is focused on the text; to see the pictures, one must press +on an icon. Many students found the right article containing the answer +to the question, but they did not click on the icon to bring up the right +figure and see it. They did not know that they had found the right place, +and thus got it wrong. + +The short answer demonstrated by this experiment was that in the event +one does not know what to read, one needs the electronic systems; the +electronic systems hold no advantage at the moment if one knows what to +read, but neither do they impose a penalty. + +LESK concluded by commenting that, on one hand, the image system was easy +to use. On the other hand, the text display system, which represented +twenty man-years of work in programming and polishing, was not winning, +because the text was not being read, just searched. The much easier +system is highly competitive as well as remarkably effective for the +actual chemists. + + ****** + ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ +ERWAY * Most challenging aspect of working on AM * Assumptions guiding +AM's approach * Testing different types of service bureaus * AM's +requirement for 99.95 percent accuracy * Requirements for text-coding * +Additional factors influencing AM's approach to coding * Results of AM's +experience with rekeying * Other problems in dealing with service bureaus +* Quality control the most time-consuming aspect of contracting out +conversion * Long-term outlook uncertain * ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ + +To Ricky ERWAY, associate coordinator, American Memory, Library of +Congress, the constant variety of conversion projects taking place +simultaneously represented perhaps the most challenging aspect of working +on AM. Thus, the challenge was not to find a solution for text +conversion but a tool kit of solutions to apply to LC's varied +collections that need to be converted. ERWAY limited her remarks to the +process of converting text to machine-readable form, and the variety of +LC's text collections, for example, bound volumes, microfilm, and +handwritten manuscripts. + +Two assumptions have guided AM's approach, ERWAY said: 1) A desire not +to perform the conversion inhouse. Because of the variety of formats and +types of texts, to capitalize the equipment and have the talents and +skills to operate them at LC would be extremely expensive. Further, the +natural inclination to upgrade to newer and better equipment each year +made it reasonable for AM to focus on what it did best and seek external +conversion services. Using service bureaus also allowed AM to have +several types of operations take place at the same time. 2) AM was not a +technology project, but an effort to improve access to library +collections. Hence, whether text was converted using OCR or rekeying +mattered little to AM. What mattered were cost and accuracy of results. + +AM considered different types of service bureaus and selected three to +perform several small tests in order to acquire a sense of the field. +The sample collections with which they worked included handwritten +correspondence, typewritten manuscripts from the 1940s, and +eighteenth-century printed broadsides on microfilm. On none of these +samples was OCR performed; they were all rekeyed. AM had several special +requirements for the three service bureaus it had engaged. For instance, +any errors in the original text were to be retained. Working from bound +volumes or anything that could not be sheet-fed also constituted a factor +eliminating companies that would have performed OCR. + +AM requires 99.95 percent accuracy, which, though it sounds high, often +means one or two errors per page. The initial batch of test samples +contained several handwritten materials for which AM did not require +text-coding. The results, ERWAY reported, were in all cases fairly +comparable: for the most part, all three service bureaus achieved 99.95 +percent accuracy. AM was satisfied with the work but surprised at the cost. + +As AM began converting whole collections, it retained the requirement for +99.95 percent accuracy and added requirements for text-coding. AM needed +to begin performing work more than three years ago before LC requirements +for SGML applications had been established. Since AM's goal was simply +to retain any of the intellectual content represented by the formatting +of the document (which would be lost if one performed a straight ASCII +conversion), AM used "SGML-like" codes. These codes resembled SGML tags +but were used without the benefit of document-type definitions. AM found +that many service bureaus were not yet SGML-proficient. + +Additional factors influencing the approach AM took with respect to +coding included: 1) the inability of any known microcomputer-based +user-retrieval software to take advantage of SGML coding; and 2) the +multiple inconsistencies in format of the older documents, which +confirmed AM in its desire not to attempt to force the different formats +to conform to a single document-type definition (DTD) and thus create the +need for a separate DTD for each document. + +The five text collections that AM has converted or is in the process of +converting include a collection of eighteenth-century broadsides, a +collection of pamphlets, two typescript document collections, and a +collection of 150 books. + +ERWAY next reviewed the results of AM's experience with rekeying, noting +again that because the bulk of AM's materials are historical, the quality +of the text often does not lend itself to OCR. While non-English +speakers are less likely to guess or elaborate or correct typos in the +original text, they are also less able to infer what we would; they also +are nearly incapable of converting handwritten text. Another +disadvantage of working with overseas keyers is that they are much less +likely to telephone with questions, especially on the coding, with the +result that they develop their own rules as they encounter new +situations. + +Government contracting procedures and time frames posed a major challenge +to performing the conversion. Many service bureaus are not accustomed to +retaining the image, even if they perform OCR. Thus, questions of image +format and storage media were somewhat novel to many of them. ERWAY also +remarked other problems in dealing with service bureaus, for example, +their inability to perform text conversion from the kind of microfilm +that LC uses for preservation purposes. + +But quality control, in ERWAY's experience, was the most time-consuming +aspect of contracting out conversion. AM has been attempting to perform +a 10-percent quality review, looking at either every tenth document or +every tenth page to make certain that the service bureaus are maintaining +99.95 percent accuracy. But even if they are complying with the +requirement for accuracy, finding errors produces a desire to correct +them and, in turn, to clean up the whole collection, which defeats the +purpose to some extent. Even a double entry requires a +character-by-character comparison to the original to meet the accuracy +requirement. LC is not accustomed to publish imperfect texts, which +makes attempting to deal with the industry standard an emotionally +fraught issue for AM. As was mentioned in the previous day's discussion, +going from 99.95 to 99.99 percent accuracy usually doubles costs and +means a third keying or another complete run-through of the text. + +Although AM has learned much from its experiences with various collections +and various service bureaus, ERWAY concluded pessimistically that no +breakthrough has been achieved. Incremental improvements have occurred +in some of the OCR technology, some of the processes, and some of the +standards acceptances, which, though they may lead to somewhat lower costs, +do not offer much encouragement to many people who are anxiously awaiting +the day that the entire contents of LC are available on-line. + + ****** + ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ +ZIDAR * Several answers to why one attempts to perform full-text +conversion * Per page cost of performing OCR * Typical problems +encountered during editing * Editing poor copy OCR vs. rekeying * ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ + +Judith ZIDAR, coordinator, National Agricultural Text Digitizing Program +(NATDP), National Agricultural Library (NAL), offered several answers to +the question of why one attempts to perform full-text conversion: 1) +Text in an image can be read by a human but not by a computer, so of +course it is not searchable and there is not much one can do with it. 2) +Some material simply requires word-level access. For instance, the legal +profession insists on full-text access to its material; with taxonomic or +geographic material, which entails numerous names, one virtually requires +word-level access. 3) Full text permits rapid browsing and searching, +something that cannot be achieved in an image with today's technology. +4) Text stored as ASCII and delivered in ASCII is standardized and highly +portable. 5) People just want full-text searching, even those who do not +know how to do it. NAL, for the most part, is performing OCR at an +actual cost per average-size page of approximately $7. NAL scans the +page to create the electronic image and passes it through the OCR device. + +ZIDAR next rehearsed several typical problems encountered during editing. +Praising the celerity of her student workers, ZIDAR observed that editing +requires approximately five to ten minutes per page, assuming that there +are no large tables to audit. Confusion among the three characters I, 1, +and l, constitutes perhaps the most common problem encountered. Zeroes +and O's also are frequently confused. Double M's create a particular +problem, even on clean pages. They are so wide in most fonts that they +touch, and the system simply cannot tell where one letter ends and the +other begins. Complex page formats occasionally fail to columnate +properly, which entails rescanning as though one were working with a +single column, entering the ASCII, and decolumnating for better +searching. With proportionally spaced text, OCR can have difficulty +discerning what is a space and what are merely spaces between letters, as +opposed to spaces between words, and therefore will merge text or break +up words where it should not. + +ZIDAR said that it can often take longer to edit a poor-copy OCR than to +key it from scratch. NAL has also experimented with partial editing of +text, whereby project workers go into and clean up the format, removing +stray characters but not running a spell-check. NAL corrects typos in +the title and authors' names, which provides a foothold for searching and +browsing. Even extremely poor-quality OCR (e.g., 60-percent accuracy) +can still be searched, because numerous words are correct, while the +important words are probably repeated often enough that they are likely +to be found correct somewhere. Librarians, however, cannot tolerate this +situation, though end users seem more willing to use this text for +searching, provided that NAL indicates that it is unedited. ZIDAR +concluded that rekeying of text may be the best route to take, in spite +of numerous problems with quality control and cost. + + ****** + ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ +DISCUSSION * Modifying an image before performing OCR * NAL's costs per +page *AM's costs per page and experience with Federal Prison Industries * +Elements comprising NATDP's costs per page * OCR and structured markup * +Distinction between the structure of a document and its representation +when put on the screen or printed * ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ + +HOOTON prefaced the lengthy discussion that followed with several +comments about modifying an image before one reaches the point of +performing OCR. For example, in regard to an application containing a +significant amount of redundant data, such as form-type data, numerous +companies today are working on various kinds of form renewal, prior to +going through a recognition process, by using dropout colors. Thus, +acquiring access to form design or using electronic means are worth +considering. HOOTON also noted that conversion usually makes or breaks +one's imaging system. It is extremely important, extremely costly in +terms of either capital investment or service, and determines the quality +of the remainder of one's system, because it determines the character of +the raw material used by the system. + +Concerning the four projects undertaken by NAL, two inside and two +performed by outside contractors, ZIDAR revealed that an in-house service +bureau executed the first at a cost between $8 and $10 per page for +everything, including building of the database. The project undertaken +by the Consultative Group on International Agricultural Research (CGIAR) +cost approximately $10 per page for the conversion, plus some expenses +for the software and building of the database. The Acid Rain Project--a +two-disk set produced by the University of Vermont, consisting of +Canadian publications on acid rain--cost $6.70 per page for everything, +including keying of the text, which was double keyed, scanning of the +images, and building of the database. The in-house project offered +considerable ease of convenience and greater control of the process. On +the other hand, the service bureaus know their job and perform it +expeditiously, because they have more people. + +As a useful comparison, ERWAY revealed AM's costs as follows: $0.75 +cents to $0.85 cents per thousand characters, with an average page +containing 2,700 characters. Requirements for coding and imaging +increase the costs. Thus, conversion of the text, including the coding, +costs approximately $3 per page. (This figure does not include the +imaging and database-building included in the NAL costs.) AM also +enjoyed a happy experience with Federal Prison Industries, which +precluded the necessity of going through the request-for-proposal process +to award a contract, because it is another government agency. The +prisoners performed AM's rekeying just as well as other service bureaus +and proved handy as well. AM shipped them the books, which they would +photocopy on a book-edge scanner. They would perform the markup on +photocopies, return the books as soon as they were done with them, +perform the keying, and return the material to AM on WORM disks. + +ZIDAR detailed the elements that constitute the previously noted cost of +approximately $7 per page. Most significant is the editing, correction +of errors, and spell-checkings, which though they may sound easy to +perform require, in fact, a great deal of time. Reformatting text also +takes a while, but a significant amount of NAL's expenses are for equipment, +which was extremely expensive when purchased because it was one of the few +systems on the market. The costs of equipment are being amortized over +five years but are still quite high, nearly $2,000 per month. + +HOCKEY raised a general question concerning OCR and the amount of editing +required (substantial in her experience) to generate the kind of +structured markup necessary for manipulating the text on the computer or +loading it into any retrieval system. She wondered if the speakers could +extend the previous question about the cost-benefit of adding or exerting +structured markup. ERWAY noted that several OCR systems retain italics, +bolding, and other spatial formatting. While the material may not be in +the format desired, these systems possess the ability to remove the +original materials quickly from the hands of the people performing the +conversion, as well as to retain that information so that users can work +with it. HOCKEY rejoined that the current thinking on markup is that one +should not say that something is italic or bold so much as why it is that +way. To be sure, one needs to know that something was italicized, but +how can one get from one to the other? One can map from the structure to +the typographic representation. + +FLEISCHHAUER suggested that, given the 100 million items the Library +holds, it may not be possible for LC to do more than report that a thing +was in italics as opposed to why it was italics, although that may be +desirable in some contexts. Promising to talk a bit during the afternoon +session about several experiments OCLC performed on automatic recognition +of document elements, and which they hoped to extend, WEIBEL said that in +fact one can recognize the major elements of a document with a fairly +high degree of reliability, at least as good as OCR. STEVENS drew a +useful distinction between standard, generalized markup (i.e., defining +for a document-type definition the structure of the document), and what +he termed a style sheet, which had to do with italics, bolding, and other +forms of emphasis. Thus, two different components are at work, one being +the structure of the document itself (its logic), and the other being its +representation when it is put on the screen or printed. + + ****** + +SESSION V. APPROACHES TO PREPARING ELECTRONIC TEXTS + ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ +HOCKEY * Text in ASCII and the representation of electronic text versus +an image * The need to look at ways of using markup to assist retrieval * +The need for an encoding format that will be reusable and multifunctional ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ + +Susan HOCKEY, director, Center for Electronic Texts in the Humanities +(CETH), Rutgers and Princeton Universities, announced that one talk +(WEIBEL's) was moved into this session from the morning and that David +Packard was unable to attend. The session would attempt to focus more on +what one can do with a text in ASCII and the representation of electronic +text rather than just an image, what one can do with a computer that +cannot be done with a book or an image. It would be argued that one can +do much more than just read a text, and from that starting point one can +use markup and methods of preparing the text to take full advantage of +the capability of the computer. That would lead to a discussion of what +the European Community calls REUSABILITY, what may better be termed +DURABILITY, that is, how to prepare or make a text that will last a long +time and that can be used for as many applications as possible, which +would lead to issues of improving intellectual access. + +HOCKEY urged the need to look at ways of using markup to facilitate retrieval, +not just for referencing or to help locate an item that is retrieved, but also to put markup tags in +a text to help retrieve the thing sought either with linguistic tagging or +interpretation. HOCKEY also argued that little advancement had occurred in +the software tools currently available for retrieving and searching text. +She pressed the desideratum of going beyond Boolean searches and performing +more sophisticated searching, which the insertion of more markup in the text +would facilitate. Thinking about electronic texts as opposed to images means +considering material that will never appear in print form, or print will not +be its primary form, that is, material which only appears in electronic form. +HOCKEY alluded to the history and the need for markup and tagging and +electronic text, which was developed through the use of computers in the +humanities; as MICHELSON had observed, Father Busa had started in 1949 +to prepare the first-ever text on the computer. + +HOCKEY remarked several large projects, particularly in Europe, for the +compilation of dictionaries, language studies, and language analysis, in +which people have built up archives of text and have begun to recognize +the need for an encoding format that will be reusable and multifunctional, +that can be used not just to print the text, which may be assumed to be a +byproduct of what one wants to do, but to structure it inside the computer +so that it can be searched, built into a Hypertext system, etc. + + ****** + ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ +WEIBEL * OCLC's approach to preparing electronic text: retroconversion, +keying of texts, more automated ways of developing data * Project ADAPT +and the CORE Project * Intelligent character recognition does not exist * +Advantages of SGML * Data should be free of procedural markup; +descriptive markup strongly advocated * OCLC's interface illustrated * +Storage requirements and costs for putting a lot of information on line * ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ + +Stuart WEIBEL, senior research scientist, Online Computer Library Center, +Inc. (OCLC), described OCLC's approach to preparing electronic text. He +argued that the electronic world into which we are moving must +accommodate not only the future but the past as well, and to some degree +even the present. Thus, starting out at one end with retroconversion and +keying of texts, one would like to move toward much more automated ways +of developing data. + +For example, Project ADAPT had to do with automatically converting +document images into a structured document database with OCR text as +indexing and also a little bit of automatic formatting and tagging of +that text. The CORE project hosted by Cornell University, Bellcore, +OCLC, the American Chemical Society, and Chemical Abstracts, constitutes +WEIBEL's principal concern at the moment. This project is an example of +converting text for which one already has a machine-readable version into +a format more suitable for electronic delivery and database searching. +(Since Michael LESK had previously described CORE, WEIBEL would say +little concerning it.) Borrowing a chemical phrase, de novo synthesis, +WEIBEL cited the Online Journal of Current Clinical Trials as an example +of de novo electronic publishing, that is, a form in which the primary +form of the information is electronic. + +Project ADAPT, then, which OCLC completed a couple of years ago and in +fact is about to resume, is a model in which one takes page images either +in paper or microfilm and converts them automatically to a searchable +electronic database, either on-line or local. The operating assumption +is that accepting some blemishes in the data, especially for +retroconversion of materials, will make it possible to accomplish more. +Not enough money is available to support perfect conversion. + +WEIBEL related several steps taken to perform image preprocessing +(processing on the image before performing optical character +recognition), as well as image postprocessing. He denied the existence +of intelligent character recognition and asserted that what is wanted is +page recognition, which is a long way off. OCLC has experimented with +merging of multiple optical character recognition systems that will +reduce errors from an unacceptable rate of 5 characters out of every +l,000 to an unacceptable rate of 2 characters out of every l,000, but it +is not good enough. It will never be perfect. + +Concerning the CORE Project, WEIBEL observed that Bellcore is taking the +topography files, extracting the page images, and converting those +topography files to SGML markup. LESK hands that data off to OCLC, which +builds that data into a Newton database, the same system that underlies +the on-line system in virtually all of the reference products at OCLC. +The long-term goal is to make the systems interoperable so that not just +Bellcore's system and OCLC's system can access this data, but other +systems can as well, and the key to that is the Z39.50 common command +language and the full-text extension. Z39.50 is fine for MARC records, +but is not enough to do it for full text (that is, make full texts +interoperable). + +WEIBEL next outlined the critical role of SGML for a variety of purposes, +for example, as noted by HOCKEY, in the world of extremely large +databases, using highly structured data to perform field searches. +WEIBEL argued that by building the structure of the data in (i.e., the +structure of the data originally on a printed page), it becomes easy to +look at a journal article even if one cannot read the characters and know +where the title or author is, or what the sections of that document would be. +OCLC wants to make that structure explicit in the database, because it will +be important for retrieval purposes. + +The second big advantage of SGML is that it gives one the ability to +build structure into the database that can be used for display purposes +without contaminating the data with instructions about how to format +things. The distinction lies between procedural markup, which tells one +where to put dots on the page, and descriptive markup, which describes +the elements of a document. + +WEIBEL believes that there should be no procedural markup in the data at +all, that the data should be completely unsullied by information about +italics or boldness. That should be left up to the display device, +whether that display device is a page printer or a screen display device. +By keeping one's database free of that kind of contamination, one can +make decisions down the road, for example, reorganize the data in ways +that are not cramped by built-in notions of what should be italic and +what should be bold. WEIBEL strongly advocated descriptive markup. As +an example, he illustrated the index structure in the CORE data. With +subsequent illustrated examples of markup, WEIBEL acknowledged the common +complaint that SGML is hard to read in its native form, although markup +decreases considerably once one gets into the body. Without the markup, +however, one would not have the structure in the data. One can pass +markup through a LaTeX processor and convert it relatively easily to a +printed version of the document. + +WEIBEL next illustrated an extremely cluttered screen dump of OCLC's +system, in order to show as much as possible the inherent capability on +the screen. (He noted parenthetically that he had become a supporter of +X-Windows as a result of the progress of the CORE Project.) WEIBEL also +illustrated the two major parts of the interface: l) a control box that +allows one to generate lists of items, which resembles a small table of +contents based on key words one wishes to search, and 2) a document +viewer, which is a separate process in and of itself. He demonstrated +how to follow links through the electronic database simply by selecting +the appropriate button and bringing them up. He also noted problems that +remain to be accommodated in the interface (e.g., as pointed out by LESK, +what happens when users do not click on the icon for the figure). + +Given the constraints of time, WEIBEL omitted a large number of ancillary +items in order to say a few words concerning storage requirements and +what will be required to put a lot of things on line. Since it is +extremely expensive to reconvert all of this data, especially if it is +just in paper form (and even if it is in electronic form in typesetting +tapes), he advocated building journals electronically from the start. In +that case, if one only has text graphics and indexing (which is all that +one needs with de novo electronic publishing, because there is no need to +go back and look at bit-maps of pages), one can get 10,000 journals of +full text, or almost 6 million pages per year. These pages can be put in +approximately 135 gigabytes of storage, which is not all that much, +WEIBEL said. For twenty years, something less than three terabytes would +be required. WEIBEL calculated the costs of storing this information as +follows: If a gigabyte costs approximately $1,000, then a terabyte costs +approximately $1 million to buy in terms of hardware. One also needs a +building to put it in and a staff like OCLC to handle that information. +So, to support a terabyte, multiply by five, which gives $5 million per +year for a supported terabyte of data. + + ****** + ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ +DISCUSSION * Tapes saved by ACS are the typography files originally +supporting publication of the journal * Cost of building tagged text into +the database * ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ + +During the question-and-answer period that followed WEIBEL's +presentation, these clarifications emerged. The tapes saved by the +American Chemical Society are the typography files that originally +supported the publication of the journal. Although they are not tagged +in SGML, they are tagged in very fine detail. Every single sentence is +marked, all the registry numbers, all the publications issues, dates, and +volumes. No cost figures on tagging material on a per-megabyte basis +were available. Because ACS's typesetting system runs from tagged text, +there is no extra cost per article. It was unknown what it costs ACS to +keyboard the tagged text rather than just keyboard the text in the +cheapest process. In other words, since one intends to publish things +and will need to build tagged text into a typography system in any case, +if one does that in such a way that it can drive not only typography but +an electronic system (which is what ACS intends to do--move to SGML +publishing), the marginal cost is zero. The marginal cost represents the +cost of building tagged text into the database, which is small. + + ****** + ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ +SPERBERG-McQUEEN * Distinction between texts and computers * Implications +of recognizing that all representation is encoding * Dealing with +complicated representations of text entails the need for a grammar of +documents * Variety of forms of formal grammars * Text as a bit-mapped +image does not represent a serious attempt to represent text in +electronic form * SGML, the TEI, document-type declarations, and the +reusability and longevity of data * TEI conformance explicitly allows +extension or modification of the TEI tag set * Administrative background +of the TEI * Several design goals for the TEI tag set * An absolutely +fixed requirement of the TEI Guidelines * Challenges the TEI has +attempted to face * Good texts not beyond economic feasibility * The +issue of reproducibility or processability * The issue of mages as +simulacra for the text redux * One's model of text determines what one's +software can do with a text and has economic consequences * ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ + +Prior to speaking about SGML and markup, Michael SPERBERG-McQUEEN, editor, +Text Encoding Initiative (TEI), University of Illinois-Chicago, first drew +a distinction between texts and computers: Texts are abstract cultural +and linguistic objects while computers are complicated physical devices, +he said. Abstract objects cannot be placed inside physical devices; with +computers one can only represent text and act upon those representations. + +The recognition that all representation is encoding, SPERBERG-McQUEEN +argued, leads to the recognition of two things: 1) The topic description +for this session is slightly misleading, because there can be no discussion +of pros and cons of text-coding unless what one means is pros and cons of +working with text with computers. 2) No text can be represented in a +computer without some sort of encoding; images are one way of encoding text, +ASCII is another, SGML yet another. There is no encoding without some +information loss, that is, there is no perfect reproduction of a text that +allows one to do away with the original. Thus, the question becomes, +What is the most useful representation of text for a serious work? +This depends on what kind of serious work one is talking about. + +The projects demonstrated the previous day all involved highly complex +information and fairly complex manipulation of the textual material. +In order to use that complicated information, one has to calculate it +slowly or manually and store the result. It needs to be stored, therefore, +as part of one's representation of the text. Thus, one needs to store the +structure in the text. To deal with complicated representations of text, +one needs somehow to control the complexity of the representation of a text; +that means one needs a way of finding out whether a document and an +electronic representation of a document is legal or not; and that +means one needs a grammar of documents. + +SPERBERG-McQUEEN discussed the variety of forms of formal grammars, +implicit and explicit, as applied to text, and their capabilities. He +argued that these grammars correspond to different models of text that +different developers have. For example, one implicit model of the text +is that there is no internal structure, but just one thing after another, +a few characters and then perhaps a start-title command, and then a few +more characters and an end-title command. SPERBERG-McQUEEN also +distinguished several kinds of text that have a sort of hierarchical +structure that is not very well defined, which, typically, corresponds +to grammars that are not very well defined, as well as hierarchies that +are very well defined (e.g., the Thesaurus Linguae Graecae) and extremely +complicated things such as SGML, which handle strictly hierarchical data +very nicely. + +SPERBERG-McQUEEN conceded that one other model not illustrated on his two +displays was the model of text as a bit-mapped image, an image of a page, +and confessed to having been converted to a limited extent by the +Workshop to the view that electronic images constitute a promising, +probably superior alternative to microfilming. But he was not convinced +that electronic images represent a serious attempt to represent text in +electronic form. Many of their problems stem from the fact that they are +not direct attempts to represent the text but attempts to represent the +page, thus making them representations of representations. + +In this situation of increasingly complicated textual information and the +need to control that complexity in a useful way (which begs the question +of the need for good textual grammars), one has the introduction of SGML. +With SGML, one can develop specific document-type declarations +for specific text types or, as with the TEI, attempts to generate +general document-type declarations that can handle all sorts of text. +The TEI is an attempt to develop formats for text representation that +will ensure the kind of reusability and longevity of data discussed earlier. +It offers a way to stay alive in the state of permanent technological +revolution. + +It has been a continuing challenge in the TEI to create document grammars +that do some work in controlling the complexity of the textual object but +also allowing one to represent the real text that one will find. +Fundamental to the notion of the TEI is that TEI conformance allows one +the ability to extend or modify the TEI tag set so that it fits the text +that one is attempting to represent. + +SPERBERG-McQUEEN next outlined the administrative background of the TEI. +The TEI is an international project to develop and disseminate guidelines +for the encoding and interchange of machine-readable text. It is +sponsored by the Association for Computers in the Humanities, the +Association for Computational Linguistics, and the Association for +Literary and Linguistic Computing. Representatives of numerous other +professional societies sit on its advisory board. The TEI has a number +of affiliated projects that have provided assistance by testing drafts of +the guidelines. + +Among the design goals for the TEI tag set, the scheme first of all must +meet the needs of research, because the TEI came out of the research +community, which did not feel adequately served by existing tag sets. +The tag set must be extensive as well as compatible with existing and +emerging standards. In 1990, version 1.0 of the Guidelines was released +(SPERBERG-McQUEEN illustrated their contents). + +SPERBERG-McQUEEN noted that one problem besetting electronic text has +been the lack of adequate internal or external documentation for many +existing electronic texts. The TEI guidelines as currently formulated +contain few fixed requirements, but one of them is this: There must +always be a document header, an in-file SGML tag that provides +1) a bibliographic description of the electronic object one is talking +about (that is, who included it, when, what for, and under which title); +and 2) the copy text from which it was derived, if any. If there was +no copy text or if the copy text is unknown, then one states as much. +Version 2.0 of the Guidelines was scheduled to be completed in fall 1992 +and a revised third version is to be presented to the TEI advisory board +for its endorsement this coming winter. The TEI itself exists to provide +a markup language, not a marked-up text. + +Among the challenges the TEI has attempted to face is the need for a +markup language that will work for existing projects, that is, handle the +level of markup that people are using now to tag only chapter, section, +and paragraph divisions and not much else. At the same time, such a +language also will be able to scale up gracefully to handle the highly +detailed markup which many people foresee as the future destination of +much electronic text, and which is not the future destination but the +present home of numerous electronic texts in specialized areas. + +SPERBERG-McQUEEN dismissed the lowest-common-denominator approach as +unable to support the kind of applications that draw people who have +never been in the public library regularly before, and make them come +back. He advocated more interesting text and more intelligent text. +Asserting that it is not beyond economic feasibility to have good texts, +SPERBERG-McQUEEN noted that the TEI Guidelines listing 200-odd tags +contains tags that one is expected to enter every time the relevant +textual feature occurs. It contains all the tags that people need now, +and it is not expected that everyone will tag things in the same way. + +The question of how people will tag the text is in large part a function +of their reaction to what SPERBERG-McQUEEN termed the issue of +reproducibility. What one needs to be able to reproduce are the things +one wants to work with. Perhaps a more useful concept than that of +reproducibility or recoverability is that of processability, that is, +what can one get from an electronic text without reading it again +in the original. He illustrated this contention with a page from +Jan Comenius's bilingual Introduction to Latin. + +SPERBERG-McQUEEN returned at length to the issue of images as simulacra +for the text, in order to reiterate his belief that in the long run more +than images of pages of particular editions of the text are needed, +because just as second-generation photocopies and second-generation +microfilm degenerate, so second-generation representations tend to +degenerate, and one tends to overstress some relatively trivial aspects +of the text such as its layout on the page, which is not always +significant, despite what the text critics might say, and slight other +pieces of information such as the very important lexical ties between the +English and Latin versions of Comenius's bilingual text, for example. +Moreover, in many crucial respects it is easy to fool oneself concerning +what a scanned image of the text will accomplish. For example, in order +to study the transmission of texts, information concerning the text +carrier is necessary, which scanned images simply do not always handle. +Further, even the high-quality materials being produced at Cornell use +much of the information that one would need if studying those books as +physical objects. It is a choice that has been made. It is an arguably +justifiable choice, but one does not know what color those pen strokes in +the margin are or whether there was a stain on the page, because it has +been filtered out. One does not know whether there were rips in the page +because they do not show up, and on a couple of the marginal marks one +loses half of the mark because the pen is very light and the scanner +failed to pick it up, and so what is clearly a checkmark in the margin of +the original becomes a little scoop in the margin of the facsimile. +Standard problems for facsimile editions, not new to electronics, but +also true of light-lens photography, and are remarked here because it is +important that we not fool ourselves that even if we produce a very nice +image of this page with good contrast, we are not replacing the +manuscript any more than microfilm has replaced the manuscript. + +The TEI comes from the research community, where its first allegiance +lies, but it is not just an academic exercise. It has relevance far +beyond those who spend all of their time studying text, because one's +model of text determines what one's software can do with a text. Good +models lead to good software. Bad models lead to bad software. That has +economic consequences, and it is these economic consequences that have +led the European Community to help support the TEI, and that will lead, +SPERBERG-McQUEEN hoped, some software vendors to realize that if they +provide software with a better model of the text they can make a killing. + + ****** + ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ +DISCUSSION * Implications of different DTDs and tag sets * ODA versus SGML * ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ + +During the discussion that followed, several additional points were made. +Neither AAP (i.e., Association of American Publishers) nor CALS (i.e., +Computer-aided Acquisition and Logistics Support) has a document-type +definition for ancient Greek drama, although the TEI will be able to +handle that. Given this state of affairs and assuming that the +technical-journal producers and the commercial vendors decide to use the +other two types, then an institution like the Library of Congress, which +might receive all of their publications, would have to be able to handle +three different types of document definitions and tag sets and be able to +distinguish among them. + +Office Document Architecture (ODA) has some advantages that flow from its +tight focus on office documents and clear directions for implementation. +Much of the ODA standard is easier to read and clearer at first reading +than the SGML standard, which is extremely general. What that means is +that if one wants to use graphics in TIFF and ODA, one is stuck, because +ODA defines graphics formats while TIFF does not, whereas SGML says the +world is not waiting for this work group to create another graphics format. +What is needed is an ability to use whatever graphics format one wants. + +The TEI provides a socket that allows one to connect the SGML document to +the graphics. The notation that the graphics are in is clearly a choice +that one needs to make based on her or his environment, and that is one +advantage. SGML is less megalomaniacal in attempting to define formats +for all kinds of information, though more megalomaniacal in attempting to +cover all sorts of documents. The other advantage is that the model of +text represented by SGML is simply an order of magnitude richer and more +flexible than the model of text offered by ODA. Both offer hierarchical +structures, but SGML recognizes that the hierarchical model of the text +that one is looking at may not have been in the minds of the designers, +whereas ODA does not. + +ODA is not really aiming for the kind of document that the TEI wants to +encompass. The TEI can handle the kind of material ODA has, as well as a +significantly broader range of material. ODA seems to be very much +focused on office documents, which is what it started out being called-- +office document architecture. + + ****** + ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ +CALALUCA * Text-encoding from a publisher's perspective * +Responsibilities of a publisher * Reproduction of Migne's Latin series +whole and complete with SGML tags based on perceived need and expected +use * Particular decisions arising from the general decision to produce +and publish PLD * ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ + +The final speaker in this session, Eric CALALUCA, vice president, +Chadwyck-Healey, Inc., spoke from the perspective of a publisher re +text-encoding, rather than as one qualified to discuss methods of +encoding data, and observed that the presenters sitting in the room, +whether they had chosen to or not, were acting as publishers: making +choices, gathering data, gathering information, and making assessments. +CALALUCA offered the hard-won conviction that in publishing very large +text files (such as PLD), one cannot avoid making personal judgments of +appropriateness and structure. + +In CALALUCA's view, encoding decisions stem from prior judgments. Two +notions have become axioms for him in the consideration of future sources +for electronic publication: 1) electronic text publishing is as personal +as any other kind of publishing, and questions of if and how to encode +the data are simply a consequence of that prior decision; 2) all +personal decisions are open to criticism, which is unavoidable. + +CALALUCA rehearsed his role as a publisher or, better, as an intermediary +between what is viewed as a sound idea and the people who would make use +of it. Finding the specialist to advise in this process is the core of +that function. The publisher must monitor and hug the fine line between +giving users what they want and suggesting what they might need. One +responsibility of a publisher is to represent the desires of scholars and +research librarians as opposed to bullheadedly forcing them into areas +they would not choose to enter. + +CALALUCA likened the questions being raised today about data structure +and standards to the decisions faced by the Abbe Migne himself during +production of the Patrologia series in the mid-nineteenth century. +Chadwyck-Healey's decision to reproduce Migne's Latin series whole and +complete with SGML tags was also based upon a perceived need and an +expected use. In the same way that Migne's work came to be far more than +a simple handbook for clerics, PLD is already far more than a database +for theologians. It is a bedrock source for the study of Western +civilization, CALALUCA asserted. + +In regard to the decision to produce and publish PLD, the editorial board +offered direct judgments on the question of appropriateness of these +texts for conversion, their encoding and their distribution, and +concluded that the best possible project was one that avoided overt +intrusions or exclusions in so important a resource. Thus, the general +decision to transmit the original collection as clearly as possible with +the widest possible avenues for use led to other decisions: 1) To encode +the data or not, SGML or not, TEI or not. Again, the expected user +community asserted the need for normative tagging structures of important +humanities texts, and the TEI seemed the most appropriate structure for +that purpose. Research librarians, who are trained to view the larger +impact of electronic text sources on 80 or 90 or 100 doctoral +disciplines, loudly approved the decision to include tagging. They see +what is coming better than the specialist who is completely focused on +one edition of Ambrose's De Anima, and they also understand that the +potential uses exceed present expectations. 2) What will be tagged and +what will not. Once again, the board realized that one must tag the +obvious. But in no way should one attempt to identify through encoding +schemes every single discrete area of a text that might someday be +searched. That was another decision. Searching by a column number, an +author, a word, a volume, permitting combination searches, and tagging +notations seemed logical choices as core elements. 3) How does one make +the data available? Tieing it to a CD-ROM edition creates limitations, +but a magnetic tape file that is very large, is accompanied by the +encoding specifications, and that allows one to make local modifications +also allows one to incorporate any changes one may desire within the +bounds of private research, though exporting tag files from a CD-ROM +could serve just as well. Since no one on the board could possibly +anticipate each and every way in which a scholar might choose to mine +this data bank, it was decided to satisfy the basics and make some +provisions for what might come. 4) Not to encode the database would rob +it of the interchangeability and portability these important texts should +accommodate. For CALALUCA, the extensive options presented by full-text +searching require care in text selection and strongly support encoding of +data to facilitate the widest possible search strategies. Better +software can always be created, but summoning the resources, the people, +and the energy to reconvert the text is another matter. + +PLD is being encoded, captured, and distributed, because to +Chadwyck-Healey and the board it offers the widest possible array of +future research applications that can be seen today. CALALUCA concluded +by urging the encoding of all important text sources in whatever way +seems most appropriate and durable at the time, without blanching at the +thought that one's work may require emendation in the future. (Thus, +Chadwyck-Healey produced a very large humanities text database before the +final release of the TEI Guidelines.) + + ****** + ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ +DISCUSSION * Creating texts with markup advocated * Trends in encoding * +The TEI and the issue of interchangeability of standards * A +misconception concerning the TEI * Implications for an institution like +LC in the event that a multiplicity of DTDs develops * Producing images +as a first step towards possible conversion to full text through +character recognition * The AAP tag sets as a common starting point and +the need for caution * ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ + +HOCKEY prefaced the discussion that followed with several comments in +favor of creating texts with markup and on trends in encoding. In the +future, when many more texts are available for on-line searching, real +problems in finding what is wanted will develop, if one is faced with +millions of words of data. It therefore becomes important to consider +putting markup in texts to help searchers home in on the actual things +they wish to retrieve. Various approaches to refining retrieval methods +toward this end include building on a computer version of a dictionary +and letting the computer look up words in it to obtain more information +about the semantic structure or semantic field of a word, its grammatical +structure, and syntactic structure. + +HOCKEY commented on the present keen interest in the encoding world +in creating: 1) machine-readable versions of dictionaries that can be +initially tagged in SGML, which gives a structure to the dictionary entry; +these entries can then be converted into a more rigid or otherwise +different database structure inside the computer, which can be treated as +a dynamic tool for searching mechanisms; 2) large bodies of text to study +the language. In order to incorporate more sophisticated mechanisms, +more about how words behave needs to be known, which can be learned in +part from information in dictionaries. However, the last ten years have +seen much interest in studying the structure of printed dictionaries +converted into computer-readable form. The information one derives about +many words from those is only partial, one or two definitions of the +common or the usual meaning of a word, and then numerous definitions of +unusual usages. If the computer is using a dictionary to help retrieve +words in a text, it needs much more information about the common usages, +because those are the ones that occur over and over again. Hence the +current interest in developing large bodies of text in computer-readable +form in order to study the language. Several projects are engaged in +compiling, for example, 100 million words. HOCKEY described one with +which she was associated briefly at Oxford University involving +compilation of 100 million words of British English: about 10 percent of +that will contain detailed linguistic tagging encoded in SGML; it will +have word class taggings, with words identified as nouns, verbs, +adjectives, or other parts of speech. This tagging can then be used by +programs which will begin to learn a bit more about the structure of the +language, and then, can go to tag more text. + +HOCKEY said that the more that is tagged accurately, the more one can +refine the tagging process and thus the bigger body of text one can build +up with linguistic tagging incorporated into it. Hence, the more tagging +or annotation there is in the text, the more one may begin to learn about +language and the more it will help accomplish more intelligent OCR. She +recommended the development of software tools that will help one begin to +understand more about a text, which can then be applied to scanning +images of that text in that format and to using more intelligence to help +one interpret or understand the text. + +HOCKEY posited the need to think about common methods of text-encoding +for a long time to come, because building these large bodies of text is +extremely expensive and will only be done once. + +In the more general discussion on approaches to encoding that followed, +these points were made: + +BESSER identified the underlying problem with standards that all have to +struggle with in adopting a standard, namely, the tension between a very +highly defined standard that is very interchangeable but does not work +for everyone because something is lacking, and a standard that is less +defined, more open, more adaptable, but less interchangeable. Contending +that the way in which people use SGML is not sufficiently defined, BESSER +wondered 1) if people resist the TEI because they think it is too defined +in certain things they do not fit into, and 2) how progress with +interchangeability can be made without frightening people away. + +SPERBERG-McQUEEN replied that the published drafts of the TEI had met +with surprisingly little objection on the grounds that they do not allow +one to handle X or Y or Z. Particular concerns of the affiliated +projects have led, in practice, to discussions of how extensions are to +be made; the primary concern of any project has to be how it can be +represented locally, thus making interchange secondary. The TEI has +received much criticism based on the notion that everything in it is +required or even recommended, which, as it happens, is a misconception +from the beginning, because none of it is required and very little is +actually actively recommended for all cases, except that one document +one's source. + +SPERBERG-McQUEEN agreed with BESSER about this trade-off: all the +projects in a set of twenty TEI-conformant projects will not necessarily +tag the material in the same way. One result of the TEI will be that the +easiest problems will be solved--those dealing with the external form of +the information; but the problem that is hardest in interchange is that +one is not encoding what another wants, and vice versa. Thus, after +the adoption of a common notation, the differences in the underlying +conceptions of what is interesting about texts become more visible. +The success of a standard like the TEI will lie in the ability of +the recipient of interchanged texts to use some of what it contains +and to add the information that was not encoded that one wants, in a +layered way, so that texts can be gradually enriched and one does not +have to put in everything all at once. Hence, having a well-behaved +markup scheme is important. + +STEVENS followed up on the paradoxical analogy that BESSER alluded to in +the example of the MARC records, namely, the formats that are the same +except that they are different. STEVENS drew a parallel between +document-type definitions and MARC records for books and serials and maps, +where one has a tagging structure and there is a text-interchange. +STEVENS opined that the producers of the information will set the terms +for the standard (i.e., develop document-type definitions for the users +of their products), creating a situation that will be problematical for +an institution like the Library of Congress, which will have to deal with +the DTDs in the event that a multiplicity of them develops. Thus, +numerous people are seeking a standard but cannot find the tag set that +will be acceptable to them and their clients. SPERBERG-McQUEEN agreed +with this view, and said that the situation was in a way worse: attempting +to unify arbitrary DTDs resembled attempting to unify a MARC record with a +bibliographic record done according to the Prussian instructions. +According to STEVENS, this situation occurred very early in the process. + +WATERS recalled from early discussions on Project Open Book the concern +of many people that merely by producing images, POB was not really +enhancing intellectual access to the material. Nevertheless, not wishing +to overemphasize the opposition between imaging and full text, WATERS +stated that POB views getting the images as a first step toward possibly +converting to full text through character recognition, if the technology +is appropriate. WATERS also emphasized that encoding is involved even +with a set of images. + +SPERBERG-McQUEEN agreed with WATERS that one can create an SGML document +consisting wholly of images. At first sight, organizing graphic images +with an SGML document may not seem to offer great advantages, but the +advantages of the scheme WATERS described would be precisely that +ability to move into something that is more of a multimedia document: +a combination of transcribed text and page images. WEIBEL concurred in +this judgment, offering evidence from Project ADAPT, where a page is +divided into text elements and graphic elements, and in fact the text +elements are organized by columns and lines. These lines may be used as +the basis for distributing documents in a network environment. As one +develops software intelligent enough to recognize what those elements +are, it makes sense to apply SGML to an image initially, that may, in +fact, ultimately become more and more text, either through OCR or edited +OCR or even just through keying. For WATERS, the labor of composing the +document and saying this set of documents or this set of images belongs +to this document constitutes a significant investment. + +WEIBEL also made the point that the AAP tag sets, while not excessively +prescriptive, offer a common starting point; they do not define the +structure of the documents, though. They have some recommendations about +DTDs one could use as examples, but they do just suggest tag sets. For +example, the CORE project attempts to use the AAP markup as much as +possible, but there are clearly areas where structure must be added. +That in no way contradicts the use of AAP tag sets. + +SPERBERG-McQUEEN noted that the TEI prepared a long working paper early +on about the AAP tag set and what it lacked that the TEI thought it +needed, and a fairly long critique of the naming conventions, which has +led to a very different style of naming in the TEI. He stressed the +importance of the opposition between prescriptive markup, the kind that a +publisher or anybody can do when producing documents de novo, and +descriptive markup, in which one has to take what the text carrier +provides. In these particular tag sets it is easy to overemphasize this +opposition, because the AAP tag set is extremely flexible. Even if one +just used the DTDs, they allow almost anything to appear almost anywhere. + + ****** + +SESSION VI. COPYRIGHT ISSUES + ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ +PETERS * Several cautions concerning copyright in an electronic +environment * Review of copyright law in the United States * The notion +of the public good and the desirability of incentives to promote it * +What copyright protects * Works not protected by copyright * The rights +of copyright holders * Publishers' concerns in today's electronic +environment * Compulsory licenses * The price of copyright in a digital +medium and the need for cooperation * Additional clarifications * Rough +justice oftentimes the outcome in numerous copyright matters * Copyright +in an electronic society * Copyright law always only sets up the +boundaries; anything can be changed by contract * ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ + +Marybeth PETERS, policy planning adviser to the Register of Copyrights, +Library of Congress, made several general comments and then opened the +floor to discussion of subjects of interest to the audience. + +Having attended several sessions in an effort to gain a sense of what +people did and where copyright would affect their lives, PETERS expressed +the following cautions: + + * If one takes and converts materials and puts them in new forms, + then, from a copyright point of view, one is creating something and + will receive some rights. + + * However, if what one is converting already exists, a question + immediately arises about the status of the materials in question. + + * Putting something in the public domain in the United States offers + some freedom from anxiety, but distributing it throughout the world + on a network is another matter, even if one has put it in the public + domain in the United States. Re foreign laws, very frequently a + work can be in the public domain in the United States but protected + in other countries. Thus, one must consider all of the places a + work may reach, lest one unwittingly become liable to being faced + with a suit for copyright infringement, or at least a letter + demanding discussion of what one is doing. + +PETERS reviewed copyright law in the United States. The U.S. +Constitution effectively states that Congress has the power to enact +copyright laws for two purposes: 1) to encourage the creation and +dissemination of intellectual works for the good of society as a whole; +and, significantly, 2) to give creators and those who package and +disseminate materials the economic rewards that are due them. + +Congress strives to strike a balance, which at times can become an +emotional issue. The United States has never accepted the notion of the +natural right of an author so much as it has accepted the notion of the +public good and the desirability of incentives to promote it. This state +of affairs, however, has created strains on the international level and +is the reason for several of the differences in the laws that we have. +Today the United States protects almost every kind of work that can be +called an expression of an author. The standard for gaining copyright +protection is simply originality. This is a low standard and means that +a work is not copied from something else, as well as shows a certain +minimal amount of authorship. One can also acquire copyright protection +for making a new version of preexisting material, provided it manifests +some spark of creativity. + +However, copyright does not protect ideas, methods, systems--only the way +that one expresses those things. Nor does copyright protect anything +that is mechanical, anything that does not involve choice, or criteria +concerning whether or not one should do a thing. For example, the +results of a process called declicking, in which one mechanically removes +impure sounds from old recordings, are not copyrightable. On the other +hand, the choice to record a song digitally and to increase the sound of +violins or to bring up the tympani constitutes the results of conversion +that are copyrightable. Moreover, if a work is protected by copyright in +the United States, one generally needs the permission of the copyright +owner to convert it. Normally, who will own the new--that is, converted- +-material is a matter of contract. In the absence of a contract, the +person who creates the new material is the author and owner. But people +do not generally think about the copyright implications until after the +fact. PETERS stressed the need when dealing with copyrighted works to +think about copyright in advance. One's bargaining power is much greater +up front than it is down the road. + +PETERS next discussed works not protected by copyright, for example, any +work done by a federal employee as part of his or her official duties is +in the public domain in the United States. The issue is not wholly free +of doubt concerning whether or not the work is in the public domain +outside the United States. Other materials in the public domain include: +any works published more than seventy-five years ago, and any work +published in the United States more than twenty-eight years ago, whose +copyright was not renewed. In talking about the new technology and +putting material in a digital form to send all over the world, PETERS +cautioned, one must keep in mind that while the rights may not be an +issue in the United States, they may be in different parts of the world, +where most countries previously employed a copyright term of the life of +the author plus fifty years. + +PETERS next reviewed the economics of copyright holding. Simply, +economic rights are the rights to control the reproduction of a work in +any form. They belong to the author, or in the case of a work made for +hire, the employer. The second right, which is critical to conversion, +is the right to change a work. The right to make new versions is perhaps +one of the most significant rights of authors, particularly in an +electronic world. The third right is the right to publish the work and +the right to disseminate it, something that everyone who deals in an +electronic medium needs to know. The basic rule is if a copy is sold, +all rights of distribution are extinguished with the sale of that copy. +The key is that it must be sold. A number of companies overcome this +obstacle by leasing or renting their product. These companies argue that +if the material is rented or leased and not sold, they control the uses +of a work. The fourth right, and one very important in a digital world, +is a right of public performance, which means the right to show the work +sequentially. For example, copyright owners control the showing of a +CD-ROM product in a public place such as a public library. The reverse +side of public performance is something called the right of public +display. Moral rights also exist, which at the federal level apply only +to very limited visual works of art, but in theory may apply under +contract and other principles. Moral rights may include the right of an +author to have his or her name on a work, the right of attribution, and +the right to object to distortion or mutilation--the right of integrity. + +The way copyright law is worded gives much latitude to activities such as +preservation; to use of material for scholarly and research purposes when +the user does not make multiple copies; and to the generation of +facsimile copies of unpublished works by libraries for themselves and +other libraries. But the law does not allow anyone to become the +distributor of the product for the entire world. In today's electronic +environment, publishers are extremely concerned that the entire world is +networked and can obtain the information desired from a single copy in a +single library. Hence, if there is to be only one sale, which publishers +may choose to live with, they will obtain their money in other ways, for +example, from access and use. Hence, the development of site licenses +and other kinds of agreements to cover what publishers believe they +should be compensated for. Any solution that the United States takes +today has to consider the international arena. + +Noting that the United States is a member of the Berne Convention and +subscribes to its provisions, PETERS described the permissions process. +She also defined compulsory licenses. A compulsory license, of which the +United States has had a few, builds into the law the right to use a work +subject to certain terms and conditions. In the international arena, +however, the ability to use compulsory licenses is extremely limited. +Thus, clearinghouses and other collectives comprise one option that has +succeeded in providing for use of a work. Often overlooked when one +begins to use copyrighted material and put products together is how +expensive the permissions process and managing it is. According to +PETERS, the price of copyright in a digital medium, whatever solution is +worked out, will include managing and assembling the database. She +strongly recommended that publishers and librarians or people with +various backgrounds cooperate to work out administratively feasible +systems, in order to produce better results. + +In the lengthy question-and-answer period that followed PETERS's +presentation, the following points emerged: + + * The Copyright Office maintains that anything mechanical and + totally exhaustive probably is not protected. In the event that + what an individual did in developing potentially copyrightable + material is not understood, the Copyright Office will ask about the + creative choices the applicant chose to make or not to make. As a + practical matter, if one believes she or he has made enough of those + choices, that person has a right to assert a copyright and someone + else must assert that the work is not copyrightable. The more + mechanical, the more automatic, a thing is, the less likely it is to + be copyrightable. + + * Nearly all photographs are deemed to be copyrightable, but no one + worries about them much, because everyone is free to take the same + image. Thus, a photographic copyright represents what is called a + "thin" copyright. The photograph itself must be duplicated, in + order for copyright to be violated. + + * The Copyright Office takes the position that X-rays are not + copyrightable because they are mechanical. It can be argued + whether or not image enhancement in scanning can be protected. One + must exercise care with material created with public funds and + generally in the public domain. An article written by a federal + employee, if written as part of official duties, is not + copyrightable. However, control over a scientific article written + by a National Institutes of Health grantee (i.e., someone who + receives money from the U.S. government), depends on NIH policy. If + the government agency has no policy (and that policy can be + contained in its regulations, the contract, or the grant), the + author retains copyright. If a provision of the contract, grant, or + regulation states that there will be no copyright, then it does not + exist. When a work is created, copyright automatically comes into + existence unless something exists that says it does not. + + * An enhanced electronic copy of a print copy of an older reference + work in the public domain that does not contain copyrightable new + material is a purely mechanical rendition of the original work, and + is not copyrightable. + + * Usually, when a work enters the public domain, nothing can remove + it. For example, Congress recently passed into law the concept of + automatic renewal, which means that copyright on any work published + between l964 and l978 does not have to be renewed in order to + receive a seventy-five-year term. But any work not renewed before + 1964 is in the public domain. + + * Concerning whether or not the United States keeps track of when + authors die, nothing was ever done, nor is anything being done at + the moment by the Copyright Office. + + * Software that drives a mechanical process is itself copyrightable. + If one changes platforms, the software itself has a copyright. The + World Intellectual Property Organization will hold a symposium 28 + March through 2 April l993, at Harvard University, on digital + technology, and will study this entire issue. If one purchases a + computer software package, such as MacPaint, and creates something + new, one receives protection only for that which has been added. + +PETERS added that often in copyright matters, rough justice is the +outcome, for example, in collective licensing, ASCAP (i.e., American +Society of Composers, Authors, and Publishers), and BMI (i.e., Broadcast +Music, Inc.), where it may seem that the big guys receive more than their +due. Of course, people ought not to copy a creative product without +paying for it; there should be some compensation. But the truth of the +world, and it is not a great truth, is that the big guy gets played on +the radio more frequently than the little guy, who has to do much more +until he becomes a big guy. That is true of every author, every +composer, everyone, and, unfortunately, is part of life. + +Copyright always originates with the author, except in cases of works +made for hire. (Most software falls into this category.) When an author +sends his article to a journal, he has not relinquished copyright, though +he retains the right to relinquish it. The author receives absolutely +everything. The less prominent the author, the more leverage the +publisher will have in contract negotiations. In order to transfer the +rights, the author must sign an agreement giving them away. + +In an electronic society, it is important to be able to license a writer +and work out deals. With regard to use of a work, it usually is much +easier when a publisher holds the rights. In an electronic era, a real +problem arises when one is digitizing and making information available. +PETERS referred again to electronic licensing clearinghouses. Copyright +ought to remain with the author, but as one moves forward globally in the +electronic arena, a middleman who can handle the various rights becomes +increasingly necessary. + +The notion of copyright law is that it resides with the individual, but +in an on-line environment, where a work can be adapted and tinkered with +by many individuals, there is concern. If changes are authorized and +there is no agreement to the contrary, the person who changes a work owns +the changes. To put it another way, the person who acquires permission +to change a work technically will become the author and the owner, unless +some agreement to the contrary has been made. It is typical for the +original publisher to try to control all of the versions and all of the +uses. Copyright law always only sets up the boundaries. Anything can be +changed by contract. + + ****** + +SESSION VII. CONCLUSION + ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ +GENERAL DISCUSSION * Two questions for discussion * Different emphases in +the Workshop * Bringing the text and image partisans together * +Desiderata in planning the long-term development of something * Questions +surrounding the issue of electronic deposit * Discussion of electronic +deposit as an allusion to the issue of standards * Need for a directory +of preservation projects in digital form and for access to their +digitized files * CETH's catalogue of machine-readable texts in the +humanities * What constitutes a publication in the electronic world? * +Need for LC to deal with the concept of on-line publishing * LC's Network +Development Office exploring the limits of MARC as a standard in terms +of handling electronic information * Magnitude of the problem and the +need for distributed responsibility in order to maintain and store +electronic information * Workshop participants to be viewed as a starting +point * Development of a network version of AM urged * A step toward AM's +construction of some sort of apparatus for network access * A delicate +and agonizing policy question for LC * Re the issue of electronic +deposit, LC urged to initiate a catalytic process in terms of distributed +responsibility * Suggestions for cooperative ventures * Commercial +publishers' fears * Strategic questions for getting the image and text +people to think through long-term cooperation * Clarification of the +driving force behind both the Perseus and the Cornell Xerox projects * ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ + +In his role as moderator of the concluding session, GIFFORD raised two +questions he believed would benefit from discussion: 1) Are there enough +commonalities among those of us that have been here for two days so that +we can see courses of action that should be taken in the future? And, if +so, what are they and who might take them? 2) Partly derivative from +that, but obviously very dangerous to LC as host, do you see a role for +the Library of Congress in all this? Of course, the Library of Congress +holds a rather special status in a number of these matters, because it is +not perceived as a player with an economic stake in them, but are there +roles that LC can play that can help advance us toward where we are heading? + +Describing himself as an uninformed observer of the technicalities of the +last two days, GIFFORD detected three different emphases in the Workshop: +1) people who are very deeply committed to text; 2) people who are almost +passionate about images; and 3) a few people who are very committed to +what happens to the networks. In other words, the new networking +dimension, the accessibility of the processability, the portability of +all this across the networks. How do we pull those three together? + +Adding a question that reflected HOCKEY's comment that this was the +fourth workshop she had attended in the previous thirty days, FLEISCHHAUER +wondered to what extent this meeting had reinvented the wheel, or if it +had contributed anything in the way of bringing together a different group +of people from those who normally appear on the workshop circuit. + +HOCKEY confessed to being struck at this meeting and the one the +Electronic Pierce Consortium organized the previous week that this was a +coming together of people working on texts and not images. Attempting to +bring the two together is something we ought to be thinking about for the +future: How one can think about working with image material to begin +with, but structuring it and digitizing it in such a way that at a later +stage it can be interpreted into text, and find a common way of building +text and images together so that they can be used jointly in the future, +with the network support to begin there because that is how people will +want to access it. + +In planning the long-term development of something, which is what is +being done in electronic text, HOCKEY stressed the importance not only +of discussing the technical aspects of how one does it but particularly +of thinking about what the people who use the stuff will want to do. +But conversely, there are numerous things that people start to do with +electronic text or material that nobody ever thought of in the beginning. + +LESK, in response to the question concerning the role of the Library of +Congress, remarked the often suggested desideratum of having electronic +deposit: Since everything is now computer-typeset, an entire decade of +material that was machine-readable exists, but the publishers frequently +did not save it; has LC taken any action to have its copyright deposit +operation start collecting these machine-readable versions? In the +absence of PETERS, GIFFORD replied that the question was being +actively considered but that that was only one dimension of the problem. +Another dimension is the whole question of the integrity of the original +electronic document. It becomes highly important in science to prove +authorship. How will that be done? + +ERWAY explained that, under the old policy, to make a claim for a +copyright for works that were published in electronic form, including +software, one had to submit a paper copy of the first and last twenty +pages of code--something that represented the work but did not include +the entire work itself and had little value to anyone. As a temporary +measure, LC has claimed the right to demand electronic versions of +electronic publications. This measure entails a proactive role for the +Library to say that it wants a particular electronic version. Publishers +then have perhaps a year to submit it. But the real problem for LC is +what to do with all this material in all these different formats. Will +the Library mount it? How will it give people access to it? How does LC +keep track of the appropriate computers, software, and media? The situation +is so hard to control, ERWAY said, that it makes sense for each publishing +house to maintain its own archive. But LC cannot enforce that either. + +GIFFORD acknowledged LESK's suggestion that establishing a priority +offered the solution, albeit a fairly complicated one. But who maintains +that register?, he asked. GRABER noted that LC does attempt to collect a +Macintosh version and the IBM-compatible version of software. It does +not collect other versions. But while true for software, BYRUM observed, +this reply does not speak to materials, that is, all the materials that +were published that were on somebody's microcomputer or driver tapes +at a publishing office across the country. LC does well to acquire +specific machine-readable products selectively that were intended to be +machine-readable. Materials that were in machine-readable form at one time, +BYRUM said, would be beyond LC's capability at the moment, insofar as +attempting to acquire, organize, and preserve them are concerned--and +preservation would be the most important consideration. In this +connection, GIFFORD reiterated the need to work out some sense of +distributive responsibility for a number of these issues, which +inevitably will require significant cooperation and discussion. +Nobody can do it all. + +LESK suggested that some publishers may look with favor on LC beginning +to serve as a depository of tapes in an electronic manuscript standard. +Publishers may view this as a service that they did not have to perform +and they might send in tapes. However, SPERBERG-McQUEEN countered, +although publishers have had equivalent services available to them for a +long time, the electronic text archive has never turned away or been +flooded with tapes and is forever sending feedback to the depositor. +Some publishers do send in tapes. + +ANDRE viewed this discussion as an allusion to the issue of standards. +She recommended that the AAP standard and the TEI, which has already been +somewhat harmonized internationally and which also shares several +compatibilities with the AAP, be harmonized to ensure sufficient +compatibility in the software. She drew the line at saying LC ought to +be the locus or forum for such harmonization. + +Taking the group in a slightly different direction, but one where at +least in the near term LC might play a helpful role, LYNCH remarked the +plans of a number of projects to carry out preservation by creating +digital images that will end up in on-line or near-line storage at some +institution. Presumably, LC will link this material somehow to its +on-line catalog in most cases. Thus, it is in a digital form. LYNCH had +the impression that many of these institutions would be willing to make +those files accessible to other people outside the institution, provided +that there is no copyright problem. This desideratum will require +propagating the knowledge that those digitized files exist, so that they +can end up in other on-line catalogs. Although uncertain about the +mechanism for achieving this result, LYNCH said that it warranted +scrutiny because it seemed to be connected to some of the basic issues of +cataloging and distribution of records. It would be foolish, given the +amount of work that all of us have to do and our meager resources, to +discover multiple institutions digitizing the same work. Re microforms, +LYNCH said, we are in pretty good shape. + +BATTIN called this a big problem and noted that the Cornell people (who +had already departed) were working on it. At issue from the beginning +was to learn how to catalog that information into RLIN and then into +OCLC, so that it would be accessible. That issue remains to be resolved. +LYNCH rejoined that putting it into OCLC or RLIN was helpful insofar as +somebody who is thinking of performing preservation activity on that work +could learn about it. It is not necessarily helpful for institutions to +make that available. BATTIN opined that the idea was that it not only be +for preservation purposes but for the convenience of people looking for +this material. She endorsed LYNCH's dictum that duplication of this +effort was to be avoided by every means. + +HOCKEY informed the Workshop about one major current activity of CETH, +namely a catalogue of machine-readable texts in the humanities. Held on +RLIN at present, the catalogue has been concentrated on ASCII as opposed +to digitized images of text. She is exploring ways to improve the +catalogue and make it more widely available, and welcomed suggestions +about these concerns. CETH owns the records, which are not just +restricted to RLIN, and can distribute them however it wishes. + +Taking up LESK's earlier question, BATTIN inquired whether LC, since it +is accepting electronic files and designing a mechanism for dealing with +that rather than putting books on shelves, would become responsible for +the National Copyright Depository of Electronic Materials. Of course +that could not be accomplished overnight, but it would be something LC +could plan for. GIFFORD acknowledged that much thought was being devoted +to that set of problems and returned the discussion to the issue raised +by LYNCH--whether or not putting the kind of records that both BATTIN and +HOCKEY have been talking about in RLIN is not a satisfactory solution. +It seemed to him that RLIN answered LYNCH's original point concerning +some kind of directory for these kinds of materials. In a situation +where somebody is attempting to decide whether or not to scan this or +film that or to learn whether or not someone has already done so, LYNCH +suggested, RLIN is helpful, but it is not helpful in the case of a local, +on-line catalogue. Further, one would like to have her or his system be +aware that that exists in digital form, so that one can present it to a +patron, even though one did not digitize it, if it is out of copyright. +The only way to make those linkages would be to perform a tremendous +amount of real-time look-up, which would be awkward at best, or +periodically to yank the whole file from RLIN and match it against one's +own stuff, which is a nuisance. + +But where, ERWAY inquired, does one stop including things that are +available with Internet, for instance, in one's local catalogue? +It almost seems that that is LC's means to acquire access to them. +That represents LC's new form of library loan. Perhaps LC's new on-line +catalogue is an amalgamation of all these catalogues on line. LYNCH +conceded that perhaps that was true in the very long term, but was not +applicable to scanning in the short term. In his view, the totals cited +by Yale, 10,000 books over perhaps a four-year period, and 1,000-1,500 +books from Cornell, were not big numbers, while searching all over +creation for relatively rare occurrences will prove to be less efficient. +As GIFFORD wondered if this would not be a separable file on RLIN and +could be requested from them, BATTIN interjected that it was easily +accessible to an institution. SEVERTSON pointed out that that file, cum +enhancements, was available with reference information on CD-ROM, which +makes it a little more available. + +In HOCKEY's view, the real question facing the Workshop is what to put in +this catalogue, because that raises the question of what constitutes a +publication in the electronic world. (WEIBEL interjected that Eric Joule +in OCLC's Office of Research is also wrestling with this particular +problem, while GIFFORD thought it sounded fairly generic.) HOCKEY +contended that a majority of texts in the humanities are in the hands +of either a small number of large research institutions or individuals +and are not generally available for anyone else to access at all. +She wondered if these texts ought to be catalogued. + +After argument proceeded back and forth for several minutes over why +cataloguing might be a necessary service, LEBRON suggested that this +issue involved the responsibility of a publisher. The fact that someone +has created something electronically and keeps it under his or her +control does not constitute publication. Publication implies +dissemination. While it would be important for a scholar to let other +people know that this creation exists, in many respects this is no +different from an unpublished manuscript. That is what is being accessed +in there, except that now one is not looking at it in the hard-copy but +in the electronic environment. + +LEBRON expressed puzzlement at the variety of ways electronic publishing +has been viewed. Much of what has been discussed throughout these two +days has concerned CD-ROM publishing, whereas in the on-line environment +that she confronts, the constraints and challenges are very different. +Sooner or later LC will have to deal with the concept of on-line +publishing. Taking up the comment ERWAY made earlier about storing +copies, LEBRON gave her own journal as an example. How would she deposit +OJCCT for copyright?, she asked, because the journal will exist in the +mainframe at OCLC and people will be able to access it. Here the +situation is different, ownership versus access, and is something that +arises with publication in the on-line environment, faster than is +sometimes realized. Lacking clear answers to all of these questions +herself, LEBRON did not anticipate that LC would be able to take a role +in helping to define some of them for quite a while. + +GREENFIELD observed that LC's Network Development Office is attempting, +among other things, to explore the limits of MARC as a standard in terms +of handling electronic information. GREENFIELD also noted that Rebecca +GUENTHER from that office gave a paper to the American Society for +Information Science (ASIS) summarizing several of the discussion papers +that were coming out of the Network Development Office. GREENFIELD said +he understood that that office had a list-server soliciting just the kind +of feedback received today concerning the difficulties of identifying and +cataloguing electronic information. GREENFIELD hoped that everybody +would be aware of that and somehow contribute to that conversation. + +Noting two of LC's roles, first, to act as a repository of record for +material that is copyrighted in this country, and second, to make +materials it holds available in some limited form to a clientele that +goes beyond Congress, BESSER suggested that it was incumbent on LC to +extend those responsibilities to all the things being published in +electronic form. This would mean eventually accepting electronic +formats. LC could require that at some point they be in a certain +limited set of formats, and then develop mechanisms for allowing people +to access those in the same way that other things are accessed. This +does not imply that they are on the network and available to everyone. +LC does that with most of its bibliographic records, BESSER said, which +end up migrating to the utility (e.g., OCLC) or somewhere else. But just +as most of LC's books are available in some form through interlibrary +loan or some other mechanism, so in the same way electronic formats ought +to be available to others in some format, though with some copyright +considerations. BESSER was not suggesting that these mechanisms be +established tomorrow, only that they seemed to fall within LC's purview, +and that there should be long-range plans to establish them. + +Acknowledging that those from LC in the room agreed with BESSER +concerning the need to confront difficult questions, GIFFORD underscored +the magnitude of the problem of what to keep and what to select. GIFFORD +noted that LC currently receives some 31,000 items per day, not counting +electronic materials, and argued for much more distributed responsibility +in order to maintain and store electronic information. + +BESSER responded that the assembled group could be viewed as a starting +point, whose initial operating premise could be helping to move in this +direction and defining how LC could do so, for example, in areas of +standardization or distribution of responsibility. + +FLEISCHHAUER added that AM was fully engaged, wrestling with some of the +questions that pertain to the conversion of older historical materials, +which would be one thing that the Library of Congress might do. Several +points mentioned by BESSER and several others on this question have a +much greater impact on those who are concerned with cataloguing and the +networking of bibliographic information, as well as preservation itself. + +Speaking directly to AM, which he considered was a largely uncopyrighted +database, LYNCH urged development of a network version of AM, or +consideration of making the data in it available to people interested in +doing network multimedia. On account of the current great shortage of +digital data that is both appealing and unencumbered by complex rights +problems, this course of action could have a significant effect on making +network multimedia a reality. + +In this connection, FLEISCHHAUER reported on a fragmentary prototype in +LC's Office of Information Technology Services that attempts to associate +digital images of photographs with cataloguing information in ways that +work within a local area network--a step, so to say, toward AM's +construction of some sort of apparatus for access. Further, AM has +attempted to use standard data forms in order to help make that +distinction between the access tools and the underlying data, and thus +believes that the database is networkable. + +A delicate and agonizing policy question for LC, however, which comes +back to resources and unfortunately has an impact on this, is to find +some appropriate, honorable, and legal cost-recovery possibilities. A +certain skittishness concerning cost-recovery has made people unsure +exactly what to do. AM would be highly receptive to discussing further +LYNCH's offer to test or demonstrate its database in a network +environment, FLEISCHHAUER said. + +Returning the discussion to what she viewed as the vital issue of +electronic deposit, BATTIN recommended that LC initiate a catalytic +process in terms of distributed responsibility, that is, bring together +the distributed organizations and set up a study group to look at all +these issues and see where we as a nation should move. The broader +issues of how we deal with the management of electronic information will +not disappear, but only grow worse. + +LESK took up this theme and suggested that LC attempt to persuade one +major library in each state to deal with its state equivalent publisher, +which might produce a cooperative project that would be equitably +distributed around the country, and one in which LC would be dealing with +a minimal number of publishers and minimal copyright problems. + +GRABER remarked the recent development in the scientific community of a +willingness to use SGML and either deposit or interchange on a fairly +standardized format. He wondered if a similar movement was taking place +in the humanities. Although the National Library of Medicine found only +a few publishers to cooperate in a like venture two or three years ago, a +new effort might generate a much larger number willing to cooperate. + +KIMBALL recounted his unit's (Machine-Readable Collections Reading Room) +troubles with the commercial publishers of electronic media in acquiring +materials for LC's collections, in particular the publishers' fear that +they would not be able to cover their costs and would lose control of +their products, that LC would give them away or sell them and make +profits from them. He doubted that the publishing industry was prepared +to move into this area at the moment, given its resistance to allowing LC +to use its machine-readable materials as the Library would like. + +The copyright law now addresses compact disk as a medium, and LC can +request one copy of that, or two copies if it is the only version, and +can request copies of software, but that fails to address magazines or +books or anything like that which is in machine-readable form. + +GIFFORD acknowledged the thorny nature of this issue, which he illustrated +with the example of the cumbersome process involved in putting a copy of a +scientific database on a LAN in LC's science reading room. He also +acknowledged that LC needs help and could enlist the energies and talents +of Workshop participants in thinking through a number of these problems. + +GIFFORD returned the discussion to getting the image and text people to +think through together where they want to go in the long term. MYLONAS +conceded that her experience at the Pierce Symposium the previous week at +Georgetown University and this week at LC had forced her to reevaluate +her perspective on the usefulness of text as images. MYLONAS framed the +issues in a series of questions: How do we acquire machine-readable +text? Do we take pictures of it and perform OCR on it later? Is it +important to obtain very high-quality images and text, etc.? +FLEISCHHAUER agreed with MYLONAS's framing of strategic questions, adding +that a large institution such as LC probably has to do all of those +things at different times. Thus, the trick is to exercise judgment. The +Workshop had added to his and AM's considerations in making those +judgments. Concerning future meetings or discussions, MYLONAS suggested +that screening priorities would be helpful. + +WEIBEL opined that the diversity reflected in this group was a sign both +of the health and of the immaturity of the field, and more time would +have to pass before we convince one another concerning standards. + +An exchange between MYLONAS and BATTIN clarified the point that the +driving force behind both the Perseus and the Cornell Xerox projects was +the preservation of knowledge for the future, not simply for particular +research use. In the case of Perseus, MYLONAS said, the assumption was +that the texts would not be entered again into electronically readable +form. SPERBERG-McQUEEN added that a scanned image would not serve as an +archival copy for purposes of preservation in the case of, say, the Bill +of Rights, in the sense that the scanned images are effectively the +archival copies for the Cornell mathematics books. + + + *** *** *** ****** *** *** *** + + + Appendix I: PROGRAM + + + + WORKSHOP + ON + ELECTRONIC + TEXTS + + + + 9-10 June 1992 + + Library of Congress + Washington, D.C. + + + + Supported by a Grant from the David and Lucile Packard Foundation + + +Tuesday, 9 June 1992 + +NATIONAL DEMONSTRATION LAB, ATRIUM, LIBRARY MADISON + +8:30 AM Coffee and Danish, registration + +9:00 AM Welcome + + Prosser Gifford, Director for Scholarly Programs, and Carl + Fleischhauer, Coordinator, American Memory, Library of + Congress + +9:l5 AM Session I.

Many of the +remarks are drawn from a report the speaker coauthored with Jeff +Rothenberg, a computer scientist at The RAND Corporation. + +The speaker assesses 1) current scholarly use of information technology +and 2) the key trends in information technology most relevant to the +research process, in order to predict how social sciences and humanities +scholars are apt to use electronic texts. In introducing the topic, +current use of electronic texts is explored broadly within the context of +scholarly communication. From the perspective of scholarly +communication, the work of humanities and social sciences scholars +involves five processes: 1) identification of sources, 2) communication +with colleagues, 3) interpretation and analysis of data, 4) dissemination +of research findings, and 5) curriculum development and instruction. The +extent to which computation currently permeates aspects of scholarly +communication represents a viable indicator of the prospects for +electronic texts. + +The discussion of current practice is balanced by an analysis of key +trends in the scholarly use of information technology. These include the +trends toward end-user computing and connectivity, which provide a +framework for forecasting the use of electronic texts through this +millennium. The presentation concludes with a summary of the ways in +which the nonscientific scholarly community can be expected to use +electronic texts, and the implications of that use for information +providers. + +Susan VECCIA and Joanne FREEMAN Electronic Archives for the Public: + Use of American Memory in Public and + School Libraries + +This joint discussion focuses on nonscholarly applications of electronic +library materials, specifically addressing use of the Library of Congress +American Memory (AM) program in a small number of public and school +libraries throughout the United States. AM consists of selected Library +of Congress primary archival materials, stored on optical media +(CD-ROM/videodisc), and presented with little or no editing. Many +collections are accompanied by electronic introductions and user's guides +offering background information and historical context. Collections +represent a variety of formats including photographs, graphic arts, +motion pictures, recorded sound, music, broadsides and manuscripts, +books, and pamphlets. + +In 1991, the Library of Congress began a nationwide evaluation of AM in +different types of institutions. Test sites include public libraries, +elementary and secondary school libraries, college and university +libraries, state libraries, and special libraries. Susan VECCIA and +Joanne FREEMAN will discuss their observations on the use of AM by the +nonscholarly community, using evidence gleaned from this ongoing +evaluation effort. + +VECCIA will comment on the overall goals of the evaluation project, and +the types of public and school libraries included in this study. Her +comments on nonscholarly use of AM will focus on the public library as a +cultural and community institution, often bridging the gap between formal +and informal education. FREEMAN will discuss the use of AM in school +libraries. Use by students and teachers has revealed some broad +questions about the use of electronic resources, as well as definite +benefits gained by the "nonscholar." Topics will include the problem of +grasping content and context in an electronic environment, the stumbling +blocks created by "new" technologies, and the unique skills and interests +awakened through use of electronic resources. + +SESSION II + +Elli MYLONAS The Perseus Project: Interactive Sources and + Studies in Classical Greece + +The Perseus Project (5) has just released Perseus 1.0, the first publicly +available version of its hypertextual database of multimedia materials on +classical Greece. Perseus is designed to be used by a wide audience, +comprised of readers at the student and scholar levels. As such, it must +be able to locate information using different strategies, and it must +contain enough detail to serve the different needs of its users. In +addition, it must be delivered so that it is affordable to its target +audience. [These problems and the solutions we chose are described in +Mylonas, "An Interface to Classical Greek Civilization," JASIS 43:2, +March 1992.] + +In order to achieve its objective, the project staff decided to make a +conscious separation between selecting and converting textual, database, +and image data on the one hand, and putting it into a delivery system on +the other. That way, it is possible to create the electronic data +without thinking about the restrictions of the delivery system. We have +made a great effort to choose system-independent formats for our data, +and to put as much thought and work as possible into structuring it so +that the translation from paper to electronic form will enhance the value +of the data. [A discussion of these solutions as of two years ago is in +Elli Mylonas, Gregory Crane, Kenneth Morrell, and D. Neel Smith, "The +Perseus Project: Data in the Electronic Age," in Accessing Antiquity: +The Computerization of Classical Databases, J. Solomon and T. Worthen +(eds.), University of Arizona Press, in press.] + +Much of the work on Perseus is focused on collecting and converting the +data on which the project is based. At the same time, it is necessary to +provide means of access to the information, in order to make it usable, +and them to investigate how it is used. As we learn more about what +students and scholars from different backgrounds do with Perseus, we can +adjust our data collection, and also modify the system to accommodate +them. In creating a delivery system for general use, we have tried to +avoid favoring any one type of use by allowing multiple forms of access +to and navigation through the system. + +The way text is handled exemplifies some of these principles. All text +in Perseus is tagged using SGML, following the guidelines of the Text +Encoding Initiative (TEI). This markup is used to index the text, and +process it so that it can be imported into HyperCard. No SGML markup +remains in the text that reaches the user, because currently it would be +too expensive to create a system that acts on SGML in real time. +However, the regularity provided by SGML is essential for verifying the +content of the texts, and greatly speeds all the processing performed on +them. The fact that the texts exist in SGML ensures that they will be +relatively easy to port to different hardware and software, and so will +outlast the current delivery platform. Finally, the SGML markup +incorporates existing canonical reference systems (chapter, verse, line, +etc.); indexing and navigation are based on these features. This ensures +that the same canonical reference will always resolve to the same point +within a text, and that all versions of our texts, regardless of delivery +platform (even paper printouts) will function the same way. + +In order to provide tools for users, the text is processed by a +morphological analyzer, and the results are stored in a database. +Together with the index, the Greek-English Lexicon, and the index of all +the English words in the definitions of the lexicon, the morphological +analyses comprise a set of linguistic tools that allow users of all +levels to work with the textual information, and to accomplish different +tasks. For example, students who read no Greek may explore a concept as +it appears in Greek texts by using the English-Greek index, and then +looking up works in the texts and translations, or scholars may do +detailed morphological studies of word use by using the morphological +analyses of the texts. Because these tools were not designed for any one +use, the same tools and the same data can be used by both students and +scholars. + +NOTES: + (5) Perseus is based at Harvard University, with collaborators at + several other universities. The project has been funded primarily + by the Annenberg/CPB Project, as well as by Harvard University, + Apple Computer, and others. It is published by Yale University + Press. Perseus runs on Macintosh computers, under the HyperCard + program. + +Eric CALALUCA + +Chadwyck-Healey embarked last year on two distinct yet related full-text +humanities database projects. + +The English Poetry Full-Text Database and the Patrologia Latina Database +represent new approaches to linguistic research resources. The size and +complexity of the projects present problems for electronic publishers, +but surmountable ones if they remain abreast of the latest possibilities +in data capture and retrieval software techniques. + +The issues which required address prior to the commencement of the +projects were legion: + + 1. Editorial selection (or exclusion) of materials in each + database + + 2. Deciding whether or not to incorporate a normative encoding + structure into the databases? + A. If one is selected, should it be SGML? + B. If SGML, then the TEI? + + 3. Deliver as CD-ROM, magnetic tape, or both? + + 4. Can one produce retrieval software advanced enough for the + postdoctoral linguist, yet accessible enough for unattended + general use? Should one try? + + 5. Re fair and liberal networking policies, what are the risks to + an electronic publisher? + + 6. How does the emergence of national and international education + networks affect the use and viability of research projects + requiring high investment? Do the new European Community + directives concerning database protection necessitate two + distinct publishing projects, one for North America and one for + overseas? + +From new notions of "scholarly fair use" to the future of optical media, +virtually every issue related to electronic publishing was aired. The +result is two projects which have been constructed to provide the quality +research resources with the fewest encumbrances to use by teachers and +private scholars. + +Dorothy TWOHIG + +In spring 1988 the editors of the papers of George Washington, John +Adams, Thomas Jefferson, James Madison, and Benjamin Franklin were +approached by classics scholar David Packard on behalf of the Packard +Humanities Foundation with a proposal to produce a CD-ROM edition of the +complete papers of each of the Founding Fathers. This electronic edition +will supplement the published volumes, making the documents widely +available to students and researchers at reasonable cost. We estimate +that our CD-ROM edition of Washington's Papers will be substantially +completed within the next two years and ready for publication. Within +the next ten years or so, similar CD-ROM editions of the Franklin, Adams, +Jefferson, and Madison papers also will be available. At the Library of +Congress's session on technology, I would like to discuss not only the +experience of the Washington Papers in producing the CD-ROM edition, but +the impact technology has had on these major editorial projects. +Already, we are editing our volumes with an eye to the material that will +be readily available in the CD-ROM edition. The completed electronic +edition will provide immense possibilities for the searching of documents +for information in a way never possible before. The kind of technical +innovations that are currently available and on the drawing board will +soon revolutionize historical research and the production of historical +documents. Unfortunately, much of this new technology is not being used +in the planning stages of historical projects, simply because many +historians are aware only in the vaguest way of its existence. At least +two major new historical editing projects are considering microfilm +editions, simply because they are not aware of the possibilities of +electronic alternatives and the advantages of the new technology in terms +of flexibility and research potential compared to microfilm. In fact, +too many of us in history and literature are still at the stage of +struggling with our PCs. There are many historical editorial projects in +progress presently, and an equal number of literary projects. While the +two fields have somewhat different approaches to textual editing, there +are ways in which electronic technology can be of service to both. + +Since few of the editors involved in the Founding Fathers CD-ROM editions +are technical experts in any sense, I hope to point out in my discussion +of our experience how many of these electronic innovations can be used +successfully by scholars who are novices in the world of new technology. +One of the major concerns of the sponsors of the multitude of new +scholarly editions is the limited audience reached by the published +volumes. Most of these editions are being published in small quantities +and the publishers' price for them puts them out of the reach not only of +individual scholars but of most public libraries and all but the largest +educational institutions. However, little attention is being given to +ways in which technology can bypass conventional publication to make +historical and literary documents more widely available. + +What attracted us most to the CD-ROM edition of The Papers of George +Washington was the fact that David Packard's aim was to make a complete +edition of all of the 135,000 documents we have collected available in an +inexpensive format that would be placed in public libraries, small +colleges, and even high schools. This would provide an audience far +beyond our present 1,000-copy, $45 published edition. Since the CD-ROM +edition will carry none of the explanatory annotation that appears in the +published volumes, we also feel that the use of the CD-ROM will lead many +researchers to seek out the published volumes. + +In addition to ignorance of new technical advances, I have found that too +many editors--and historians and literary scholars--are resistant and +even hostile to suggestions that electronic technology may enhance their +work. I intend to discuss some of the arguments traditionalists are +advancing to resist technology, ranging from distrust of the speed with +which it changes (we are already wondering what is out there that is +better than CD-ROM) to suspicion of the technical language used to +describe electronic developments. + +Maria LEBRON + +The Online Journal of Current Clinical Trials, a joint venture of the +American Association for the Advancement of Science (AAAS) and the Online +Computer Library Center, Inc. (OCLC), is the first peer-reviewed journal +to provide full text, tabular material, and line illustrations on line. +This presentation will discuss the genesis and start-up period of the +journal. Topics of discussion will include historical overview, +day-to-day management of the editorial peer review, and manuscript +tagging and publication. A demonstration of the journal and its features +will accompany the presentation. + +Lynne PERSONIUS + +Cornell University Library, Cornell Information Technologies, and Xerox +Corporation, with the support of the Commission on Preservation and +Access, and Sun Microsystems, Inc., have been collaborating in a project +to test a prototype system for recording brittle books as digital images +and producing, on demand, high-quality archival paper replacements. The +project goes beyond that, however, to investigate some of the issues +surrounding scanning, storing, retrieving, and providing access to +digital images in a network environment. + +The Joint Study in Digital Preservation began in January 1990. Xerox +provided the College Library Access and Storage System (CLASS) software, +a prototype 600-dots-per-inch (dpi) scanner, and the hardware necessary +to support network printing on the DocuTech printer housed in Cornell's +Computing and Communications Center (CCC). + +The Cornell staff using the hardware and software became an integral part +of the development and testing process for enhancements to the CLASS +software system. The collaborative nature of this relationship is +resulting in a system that is specifically tailored to the preservation +application. + +A digital library of 1,000 volumes (or approximately 300,000 images) has +been created and is stored on an optical jukebox that resides in CCC. +The library includes a collection of select mathematics monographs that +provides mathematics faculty with an opportunity to use the electronic +library. The remaining volumes were chosen for the library to test the +various capabilities of the scanning system. + +One project objective is to provide users of the Cornell library and the +library staff with the ability to request facsimiles of digitized images +or to retrieve the actual electronic image for browsing. A prototype +viewing workstation has been created by Xerox, with input into the design +by a committee of Cornell librarians and computer professionals. This +will allow us to experiment with patron access to the images that make up +the digital library. The viewing station provides search, retrieval, and +(ultimately) printing functions with enhancements to facilitate +navigation through multiple documents. + +Cornell currently is working to extend access to the digital library to +readers using workstations from their offices. This year is devoted to +the development of a network resident image conversion and delivery +server, and client software that will support readers who use Apple +Macintosh computers, IBM windows platforms, and Sun workstations. +Equipment for this development was provided by Sun Microsystems with +support from the Commission on Preservation and Access. + +During the show-and-tell session of the Workshop on Electronic Texts, a +prototype view station will be demonstrated. In addition, a display of +original library books that have been digitized will be available for +review with associated printed copies for comparison. The fifteen-minute +overview of the project will include a slide presentation that +constitutes a "tour" of the preservation digitizing process. + +The final network-connected version of the viewing station will provide +library users with another mechanism for accessing the digital library, +and will also provide the capability of viewing images directly. This +will not require special software, although a powerful computer with good +graphics will be needed. + +The Joint Study in Digital Preservation has generated a great deal of +interest in the library community. Unfortunately, or perhaps +fortunately, this project serves to raise a vast number of other issues +surrounding the use of digital technology for the preservation and use of +deteriorating library materials, which subsequent projects will need to +examine. Much work remains. + +SESSION III + +Howard BESSER Networking Multimedia Databases + +What do we have to consider in building and distributing databases of +visual materials in a multi-user environment? This presentation examines +a variety of concerns that need to be addressed before a multimedia +database can be set up in a networked environment. + +In the past it has not been feasible to implement databases of visual +materials in shared-user environments because of technological barriers. +Each of the two basic models for multi-user multimedia databases has +posed its own problem. The analog multimedia storage model (represented +by Project Athena's parallel analog and digital networks) has required an +incredibly complex (and expensive) infrastructure. The economies of +scale that make multi-user setups cheaper per user served do not operate +in an environment that requires a computer workstation, videodisc player, +and two display devices for each user. + +The digital multimedia storage model has required vast amounts of storage +space (as much as one gigabyte per thirty still images). In the past the +cost of such a large amount of storage space made this model a +prohibitive choice as well. But plunging storage costs are finally +making this second alternative viable. + +If storage no longer poses such an impediment, what do we need to +consider in building digitally stored multi-user databases of visual +materials? This presentation will examine the networking and +telecommunication constraints that must be overcome before such databases +can become commonplace and useful to a large number of people. + +The key problem is the vast size of multimedia documents, and how this +affects not only storage but telecommunications transmission time. +Anything slower than T-1 speed is impractical for files of 1 megabyte or +larger (which is likely to be small for a multimedia document). For +instance, even on a 56 Kb line it would take three minutes to transfer a +1-megabyte file. And these figures assume ideal circumstances, and do +not take into consideration other users contending for network bandwidth, +disk access time, or the time needed for remote display. Current common +telephone transmission rates would be completely impractical; few users +would be willing to wait the hour necessary to transmit a single image at +2400 baud. + +This necessitates compression, which itself raises a number of other +issues. In order to decrease file sizes significantly, we must employ +lossy compression algorithms. But how much quality can we afford to +lose? To date there has been only one significant study done of +image-quality needs for a particular user group, and this study did not +look at loss resulting from compression. Only after identifying +image-quality needs can we begin to address storage and network bandwidth +needs. + +Experience with X-Windows-based applications (such as Imagequery, the +University of California at Berkeley image database) demonstrates the +utility of a client-server topology, but also points to the limitation of +current software for a distributed environment. For example, +applications like Imagequery can incorporate compression, but current X +implementations do not permit decompression at the end user's +workstation. Such decompression at the host computer alleviates storage +capacity problems while doing nothing to address problems of +telecommunications bandwidth. + +We need to examine the effects on network through-put of moving +multimedia documents around on a network. We need to examine various +topologies that will help us avoid bottlenecks around servers and +gateways. Experience with applications such as these raise still broader +questions. How closely is the multimedia document tied to the software +for viewing it? Can it be accessed and viewed from other applications? +Experience with the MARC format (and more recently with the Z39.50 +protocols) shows how useful it can be to store documents in a form in +which they can be accessed by a variety of application software. + +Finally, from an intellectual-access standpoint, we need to address the +issue of providing access to these multimedia documents in +interdisciplinary environments. We need to examine terminology and +indexing strategies that will allow us to provide access to this material +in a cross-disciplinary way. + +Ronald LARSEN Directions in High-Performance Networking for + Libraries + +The pace at which computing technology has advanced over the past forty +years shows no sign of abating. Roughly speaking, each five-year period +has yielded an order-of-magnitude improvement in price and performance of +computing equipment. No fundamental hurdles are likely to prevent this +pace from continuing for at least the next decade. It is only in the +past five years, though, that computing has become ubiquitous in +libraries, affecting all staff and patrons, directly or indirectly. + +During these same five years, communications rates on the Internet, the +principal academic computing network, have grown from 56 kbps to 1.5 +Mbps, and the NSFNet backbone is now running 45 Mbps. Over the next five +years, communication rates on the backbone are expected to exceed 1 Gbps. +Growth in both the population of network users and the volume of network +traffic has continued to grow geometrically, at rates approaching 15 +percent per month. This flood of capacity and use, likened by some to +"drinking from a firehose," creates immense opportunities and challenges +for libraries. Libraries must anticipate the future implications of this +technology, participate in its development, and deploy it to ensure +access to the world's information resources. + +The infrastructure for the information age is being put in place. +Libraries face strategic decisions about their role in the development, +deployment, and use of this infrastructure. The emerging infrastructure +is much more than computers and communication lines. It is more than the +ability to compute at a remote site, send electronic mail to a peer +across the country, or move a file from one library to another. The next +five years will witness substantial development of the information +infrastructure of the network. + +In order to provide appropriate leadership, library professionals must +have a fundamental understanding of and appreciation for computer +networking, from local area networks to the National Research and +Education Network (NREN). This presentation addresses these +fundamentals, and how they relate to libraries today and in the near +future. + +Edwin BROWNRIGG Electronic Library Visions and Realities + +The electronic library has been a vision desired by many--and rejected by +some--since Vannevar Bush coined the term memex to describe an automated, +intelligent, personal information system. Variations on this vision have +included Ted Nelson's Xanadau, Alan Kay's Dynabook, and Lancaster's +"paperless library," with the most recent incarnation being the +"Knowledge Navigator" described by John Scully of Apple. But the reality +of library service has been less visionary and the leap to the electronic +library has eluded universities, publishers, and information technology +files. + +The Memex Research Institute (MemRI), an independent, nonprofit research +and development organization, has created an Electronic Library Program +of shared research and development in order to make the collective vision +more concrete. The program is working toward the creation of large, +indexed publicly available electronic image collections of published +documents in academic, special, and public libraries. This strategic +plan is the result of the first stage of the program, which has been an +investigation of the information technologies available to support such +an effort, the economic parameters of electronic service compared to +traditional library operations, and the business and political factors +affecting the shift from print distribution to electronic networked +access. + +The strategic plan envisions a combination of publicly searchable access +databases, image (and text) document collections stored on network "file +servers," local and remote network access, and an intellectual property +management-control system. This combination of technology and +information content is defined in this plan as an E-library or E-library +collection. Some participating sponsors are already developing projects +based on MemRI's recommended directions. + +The E-library strategy projected in this plan is a visionary one that can +enable major changes and improvements in academic, public, and special +library service. This vision is, though, one that can be realized with +today's technology. At the same time, it will challenge the political +and social structure within which libraries operate: in academic +libraries, the traditional emphasis on local collections, extending to +accreditation issues; in public libraries, the potential of electronic +branch and central libraries fully available to the public; and for +special libraries, new opportunities for shared collections and networks. + +The environment in which this strategic plan has been developed is, at +the moment, dominated by a sense of library limits. The continued +expansion and rapid growth of local academic library collections is now +clearly at an end. Corporate libraries, and even law libraries, are +faced with operating within a difficult economic climate, as well as with +very active competition from commercial information sources. For +example, public libraries may be seen as a desirable but not critical +municipal service in a time when the budgets of safety and health +agencies are being cut back. + +Further, libraries in general have a very high labor-to-cost ratio in +their budgets, and labor costs are still increasing, notwithstanding +automation investments. It is difficult for libraries to obtain capital, +startup, or seed funding for innovative activities, and those +technology-intensive initiatives that offer the potential of decreased +labor costs can provoke the opposition of library staff. + +However, libraries have achieved some considerable successes in the past +two decades by improving both their service and their credibility within +their organizations--and these positive changes have been accomplished +mostly with judicious use of information technologies. The advances in +computing and information technology have been well-chronicled: the +continuing precipitous drop in computing costs, the growth of the +Internet and private networks, and the explosive increase in publicly +available information databases. + +For example, OCLC has become one of the largest computer network +organizations in the world by creating a cooperative cataloging network +of more than 6,000 libraries worldwide. On-line public access catalogs +now serve millions of users on more than 50,000 dedicated terminals in +the United States alone. The University of California MELVYL on-line +catalog system has now expanded into an index database reference service +and supports more than six million searches a year. And, libraries have +become the largest group of customers of CD-ROM publishing technology; +more than 30,000 optical media publications such as those offered by +InfoTrac and Silver Platter are subscribed to by U.S. libraries. + +This march of technology continues and in the next decade will result in +further innovations that are extremely difficult to predict. What is +clear is that libraries can now go beyond automation of their order files +and catalogs to automation of their collections themselves--and it is +possible to circumvent the fiscal limitations that appear to obtain +today. + +This Electronic Library Strategic Plan recommends a paradigm shift in +library service, and demonstrates the steps necessary to provide improved +library services with limited capacities and operating investments. + +SESSION IV-A + +Anne KENNEY + +The Cornell/Xerox Joint Study in Digital Preservation resulted in the +recording of 1,000 brittle books as 600-dpi digital images and the +production, on demand, of high-quality and archivally sound paper +replacements. The project, which was supported by the Commission on +Preservation and Access, also investigated some of the issues surrounding +scanning, storing, retrieving, and providing access to digital images in +a network environment. + +Anne Kenney will focus on some of the issues surrounding direct scanning +as identified in the Cornell Xerox Project. Among those to be discussed +are: image versus text capture; indexing and access; image-capture +capabilities; a comparison to photocopy and microfilm; production and +cost analysis; storage formats, protocols, and standards; and the use of +this scanning technology for preservation purposes. + +The 600-dpi digital images produced in the Cornell Xerox Project proved +highly acceptable for creating paper replacements of deteriorating +originals. The 1,000 scanned volumes provided an array of image-capture +challenges that are common to nineteenth-century printing techniques and +embrittled material, and that defy the use of text-conversion processes. +These challenges include diminished contrast between text and background, +fragile and deteriorated pages, uneven printing, elaborate type faces, +faint and bold text adjacency, handwritten text and annotations, nonRoman +languages, and a proliferation of illustrated material embedded in text. +The latter category included high-frequency and low-frequency halftones, +continuous tone photographs, intricate mathematical drawings, maps, +etchings, reverse-polarity drawings, and engravings. + +The Xerox prototype scanning system provided a number of important +features for capturing this diverse material. Technicians used multiple +threshold settings, filters, line art and halftone definitions, +autosegmentation, windowing, and software-editing programs to optimize +image capture. At the same time, this project focused on production. +The goal was to make scanning as affordable and acceptable as +photocopying and microfilming for preservation reformatting. A +time-and-cost study conducted during the last three months of this +project confirmed the economic viability of digital scanning, and these +findings will be discussed here. + +From the outset, the Cornell Xerox Project was predicated on the use of +nonproprietary standards and the use of common protocols when standards +did not exist. Digital files were created as TIFF images which were +compressed prior to storage using Group 4 CCITT compression. The Xerox +software is MS DOS based and utilizes off-the shelf programs such as +Microsoft Windows and Wang Image Wizard. The digital library is designed +to be hardware-independent and to provide interchangeability with other +institutions through network connections. Access to the digital files +themselves is two-tiered: Bibliographic records for the computer files +are created in RLIN and Cornell's local system and access into the actual +digital images comprising a book is provided through a document control +structure and a networked image file-server, both of which will be +described. + +The presentation will conclude with a discussion of some of the issues +surrounding the use of this technology as a preservation tool (storage, +refreshing, backup). + +Pamela ANDRE and Judith ZIDAR + +The National Agricultural Library (NAL) has had extensive experience with +raster scanning of printed materials. Since 1987, the Library has +participated in the National Agricultural Text Digitizing Project (NATDP) +a cooperative effort between NAL and forty-five land grant university +libraries. An overview of the project will be presented, giving its +history and NAL's strategy for the future. + +An in-depth discussion of NATDP will follow, including a description of +the scanning process, from the gathering of the printed materials to the +archiving of the electronic pages. The type of equipment required for a +stand-alone scanning workstation and the importance of file management +software will be discussed. Issues concerning the images themselves will +be addressed briefly, such as image format; black and white versus color; +gray scale versus dithering; and resolution. + +Also described will be a study currently in progress by NAL to evaluate +the usefulness of converting microfilm to electronic images in order to +improve access. With the cooperation of Tuskegee University, NAL has +selected three reels of microfilm from a collection of sixty-seven reels +containing the papers, letters, and drawings of George Washington Carver. +The three reels were converted into 3,500 electronic images using a +specialized microfilm scanner. The selection, filming, and indexing of +this material will be discussed. + +Donald WATERS + +Project Open Book, the Yale University Library's effort to convert 10, +000 books from microfilm to digital imagery, is currently in an advanced +state of planning and organization. The Yale Library has selected a +major vendor to serve as a partner in the project and as systems +integrator. In its proposal, the successful vendor helped isolate areas +of risk and uncertainty as well as key issues to be addressed during the +life of the project. The Yale Library is now poised to decide what +material it will convert to digital image form and to seek funding, +initially for the first phase and then for the entire project. + +The proposal that Yale accepted for the implementation of Project Open +Book will provide at the end of three phases a conversion subsystem, +browsing stations distributed on the campus network within the Yale +Library, a subsystem for storing 10,000 books at 200 and 600 dots per +inch, and network access to the image printers. Pricing for the system +implementation assumes the existence of Yale's campus ethernet network +and its high-speed image printers, and includes other requisite hardware +and software, as well as system integration services. Proposed operating +costs include hardware and software maintenance, but do not include +estimates for the facilities management of the storage devices and image +servers. + +Yale selected its vendor partner in a formal process, partly funded by +the Commission for Preservation and Access. Following a request for +proposal, the Yale Library selected two vendors as finalists to work with +Yale staff to generate a detailed analysis of requirements for Project +Open Book. Each vendor used the results of the requirements analysis to +generate and submit a formal proposal for the entire project. This +competitive process not only enabled the Yale Library to select its +primary vendor partner but also revealed much about the state of the +imaging industry, about the varying, corporate commitments to the markets +for imaging technology, and about the varying organizational dynamics +through which major companies are responding to and seeking to develop +these markets. + +Project Open Book is focused specifically on the conversion of images +from microfilm to digital form. The technology for scanning microfilm is +readily available but is changing rapidly. In its project requirements, +the Yale Library emphasized features of the technology that affect the +technical quality of digital image production and the costs of creating +and storing the image library: What levels of digital resolution can be +achieved by scanning microfilm? How does variation in the quality of +microfilm, particularly in film produced to preservation standards, +affect the quality of the digital images? What technologies can an +operator effectively and economically apply when scanning film to +separate two-up images and to control for and correct image +imperfections? How can quality control best be integrated into +digitizing work flow that includes document indexing and storage? + +The actual and expected uses of digital images--storage, browsing, +printing, and OCR--help determine the standards for measuring their +quality. Browsing is especially important, but the facilities available +for readers to browse image documents is perhaps the weakest aspect of +imaging technology and most in need of development. As it defined its +requirements, the Yale Library concentrated on some fundamental aspects +of usability for image documents: Does the system have sufficient +flexibility to handle the full range of document types, including +monographs, multi-part and multivolume sets, and serials, as well as +manuscript collections? What conventions are necessary to identify a +document uniquely for storage and retrieval? Where is the database of +record for storing bibliographic information about the image document? +How are basic internal structures of documents, such as pagination, made +accessible to the reader? How are the image documents physically +presented on the screen to the reader? + +The Yale Library designed Project Open Book on the assumption that +microfilm is more than adequate as a medium for preserving the content of +deteriorated library materials. As planning in the project has advanced, +it is increasingly clear that the challenge of digital image technology +and the key to the success of efforts like Project Open Book is to +provide a means of both preserving and improving access to those +deteriorated materials. + +SESSION IV-B + +George THOMA + +In the use of electronic imaging for document preservation, there are +several issues to consider, such as: ensuring adequate image quality, +maintaining substantial conversion rates (through-put), providing unique +identification for automated access and retrieval, and accommodating +bound volumes and fragile material. + +To maintain high image quality, image processing functions are required +to correct the deficiencies in the scanned image. Some commercially +available systems include these functions, while some do not. The +scanned raw image must be processed to correct contrast deficiencies-- +both poor overall contrast resulting from light print and/or dark +background, and variable contrast resulting from stains and +bleed-through. Furthermore, the scan density must be adequate to allow +legibility of print and sufficient fidelity in the pseudo-halftoned gray +material. Borders or page-edge effects must be removed for both +compactibility and aesthetics. Page skew must be corrected for aesthetic +reasons and to enable accurate character recognition if desired. +Compound images consisting of both two-toned text and gray-scale +illustrations must be processed appropriately to retain the quality of +each. + +SESSION IV-C + +Jean BARONAS + +Standards publications being developed by scientists, engineers, and +business managers in Association for Information and Image Management +(AIIM) standards committees can be applied to electronic image management +(EIM) processes including: document (image) transfer, retrieval and +evaluation; optical disk and document scanning; and document design and +conversion. When combined with EIM system planning and operations, +standards can assist in generating image databases that are +interchangeable among a variety of systems. The applications of +different approaches for image-tagging, indexing, compression, and +transfer often cause uncertainty concerning EIM system compatibility, +calibration, performance, and upward compatibility, until standard +implementation parameters are established. The AIIM standards that are +being developed for these applications can be used to decrease the +uncertainty, successfully integrate imaging processes, and promote "open +systems." AIIM is an accredited American National Standards Institute +(ANSI) standards developer with more than twenty committees comprised of +300 volunteers representing users, vendors, and manufacturers. The +standards publications that are developed in these committees have +national acceptance and provide the basis for international harmonization +in the development of new International Organization for Standardization +(ISO) standards. + +This presentation describes the development of AIIM's EIM standards and a +new effort at AIIM, a database on standards projects in a wide framework +of imaging industries including capture, recording, processing, +duplication, distribution, display, evaluation, and preservation. The +AIIM Imagery Database will cover imaging standards being developed by +many organizations in many different countries. It will contain +standards publications' dates, origins, related national and +international projects, status, key words, and abstracts. The ANSI Image +Technology Standards Board requested that such a database be established, +as did the ISO/International Electrotechnical Commission Joint Task Force +on Imagery. AIIM will take on the leadership role for the database and +coordinate its development with several standards developers. + +Patricia BATTIN + + Characteristics of standards for digital imagery: + + * Nature of digital technology implies continuing volatility. + + * Precipitous standard-setting not possible and probably not + desirable. + + * Standards are a complex issue involving the medium, the + hardware, the software, and the technical capacity for + reproductive fidelity and clarity. + + * The prognosis for reliable archival standards (as defined by + librarians) in the foreseeable future is poor. + + Significant potential and attractiveness of digital technology as a + preservation medium and access mechanism. + + Productive use of digital imagery for preservation requires a + reconceptualizing of preservation principles in a volatile, + standardless world. + + Concept of managing continuing access in the digital environment + rather than focusing on the permanence of the medium and long-term + archival standards developed for the analog world. + + Transition period: How long and what to do? + + * Redefine "archival." + + * Remove the burden of "archival copy" from paper artifacts. + + * Use digital technology for storage, develop management + strategies for refreshing medium, hardware and software. + + * Create acid-free paper copies for transition period backup + until we develop reliable procedures for ensuring continuing + access to digital files. + +SESSION IV-D + +Stuart WEIBEL The Role of SGML Markup in the CORE Project (6) + +The emergence of high-speed telecommunications networks as a basic +feature of the scholarly workplace is driving the demand for electronic +document delivery. Three distinct categories of electronic +publishing/republishing are necessary to support access demands in this +emerging environment: + + 1.) Conversion of paper or microfilm archives to electronic format + 2.) Conversion of electronic files to formats tailored to + electronic retrieval and display + 3.) Primary electronic publishing (materials for which the + electronic version is the primary format) + +OCLC has experimental or product development activities in each of these +areas. Among the challenges that lie ahead is the integration of these +three types of information stores in coherent distributed systems. + +The CORE (Chemistry Online Retrieval Experiment) Project is a model for +the conversion of large text and graphics collections for which +electronic typesetting files are available (category 2). The American +Chemical Society has made available computer typography files dating from +1980 for its twenty journals. This collection of some 250 journal-years +is being converted to an electronic format that will be accessible +through several end-user applications. + +The use of Standard Generalized Markup Language (SGML) offers the means +to capture the structural richness of the original articles in a way that +will support a variety of retrieval, navigation, and display options +necessary to navigate effectively in very large text databases. + +An SGML document consists of text that is marked up with descriptive tags +that specify the function of a given element within the document. As a +formal language construct, an SGML document can be parsed against a +document-type definition (DTD) that unambiguously defines what elements +are allowed and where in the document they can (or must) occur. This +formalized map of article structure allows the user interface design to +be uncoupled from the underlying database system, an important step +toward interoperability. Demonstration of this separability is a part of +the CORE project, wherein user interface designs born of very different +philosophies will access the same database. + +NOTES: + (6) The CORE project is a collaboration among Cornell University's + Mann Library, Bell Communications Research (Bellcore), the American + Chemical Society (ACS), the Chemical Abstracts Service (CAS), and + OCLC. + +Michael LESK The CORE Electronic Chemistry Library + +A major on-line file of chemical journal literature complete with +graphics is being developed to test the usability of fully electronic +access to documents, as a joint project of Cornell University, the +American Chemical Society, the Chemical Abstracts Service, OCLC, and +Bellcore (with additional support from Sun Microsystems, Springer-Verlag, +DigitaI Equipment Corporation, Sony Corporation of America, and Apple +Computers). Our file contains the American Chemical Society's on-line +journals, supplemented with the graphics from the paper publication. The +indexing of the articles from Chemical Abstracts Documents is available +in both image and text format, and several different interfaces can be +used. Our goals are (1) to assess the effectiveness and acceptability of +electronic access to primary journals as compared with paper, and (2) to +identify the most desirable functions of the user interface to an +electronic system of journals, including in particular a comparison of +page-image display with ASCII display interfaces. Early experiments with +chemistry students on a variety of tasks suggest that searching tasks are +completed much faster with any electronic system than with paper, but +that for reading all versions of the articles are roughly equivalent. + +Pamela ANDRE and Judith ZIDAR + +Text conversion is far more expensive and time-consuming than image +capture alone. NAL's experience with optical character recognition (OCR) +will be related and compared with the experience of having text rekeyed. +What factors affect OCR accuracy? How accurate does full text have to be +in order to be useful? How do different users react to imperfect text? +These are questions that will be explored. For many, a service bureau +may be a better solution than performing the work inhouse; this will also +be discussed. + +SESSION VI + +Marybeth PETERS + +Copyright law protects creative works. Protection granted by the law to +authors and disseminators of works includes the right to do or authorize +the following: reproduce the work, prepare derivative works, distribute +the work to the public, and publicly perform or display the work. In +addition, copyright owners of sound recordings and computer programs have +the right to control rental of their works. These rights are not +unlimited; there are a number of exceptions and limitations. + +An electronic environment places strains on the copyright system. +Copyright owners want to control uses of their work and be paid for any +use; the public wants quick and easy access at little or no cost.

We had heard of this etext for years but it +was not until 1991 that we actually managed to track it down to +a specific location, and then it took months to convince people +to let us have a copy, then more months for them actually to do +the copying and get it to us. Then another month to convert to +something we could massage with our favorite 486 in DOS. After +that is was only a matter of days to get it into this shape you +will see below. The original was, of course, in CAPS only, and +so were all the other etexts of the 60's and early 70's. Don't +let anyone fool you into thinking any etext with both upper and +lower case is an original; all those original Project Gutenberg +etexts were also in upper case and were translated or rewritten +many times to get them into their current condition. They have +been worked on by many people throughout the world. + +In the course of our searches for Professor Raben and his etext +we were never able to determine where copies were or which of a +variety of editions he may have used as a source. We did get a +little information here and there, but even after we received a +copy of the etext we were unwilling to release it without first +determining that it was in fact Public Domain and finding Raben +to verify this and get his permission. Interested enough, in a +totally unrelated action to our searches for him, the professor +subscribed to the Project Gutenberg listserver and we happened, +by accident, to notice his name. (We don't really look at every +subscription request as the computers usually handle them.) The +etext was then properly identified, copyright analyzed, and the +current edition prepared. + +To give you an estimation of the difference in the original and +what we have today: the original was probably entered on cards +commonly known at the time as "IBM cards" (Do Not Fold, Spindle +or Mutilate) and probably took in excess of 100,000 of them. A +single card could hold 80 characters (hence 80 characters is an +accepted standard for so many computer margins), and the entire +original edition we received in all caps was over 800,000 chars +in length, including line enumeration, symbols for caps and the +punctuation marks, etc., since they were not available keyboard +characters at the time (probably the keyboards operated at baud +rates of around 113, meaning the typists had to type slowly for +the keyboard to keep up). + +This is the second version of Paradise Lost released by Project +Gutenberg. The first was released as our October, 1991 etext. + + + + + +Paradise Lost + + + + +Book I + + +Of Man's first disobedience, and the fruit +Of that forbidden tree whose mortal taste +Brought death into the World, and all our woe, +With loss of Eden, till one greater Man +Restore us, and regain the blissful seat, +Sing, Heavenly Muse, that, on the secret top +Of Oreb, or of Sinai, didst inspire +That shepherd who first taught the chosen seed +In the beginning how the heavens and earth +Rose out of Chaos: or, if Sion hill +Delight thee more, and Siloa's brook that flowed +Fast by the oracle of God, I thence +Invoke thy aid to my adventurous song, +That with no middle flight intends to soar +Above th' Aonian mount, while it pursues +Things unattempted yet in prose or rhyme. +And chiefly thou, O Spirit, that dost prefer +Before all temples th' upright heart and pure, +Instruct me, for thou know'st; thou from the first +Wast present, and, with mighty wings outspread, +Dove-like sat'st brooding on the vast Abyss, +And mad'st it pregnant: what in me is dark +Illumine, what is low raise and support; +That, to the height of this great argument, +I may assert Eternal Providence, +And justify the ways of God to men. + Say first--for Heaven hides nothing from thy view, +Nor the deep tract of Hell--say first what cause +Moved our grand parents, in that happy state, +Favoured of Heaven so highly, to fall off +From their Creator, and transgress his will +For one restraint, lords of the World besides. +Who first seduced them to that foul revolt? + Th' infernal Serpent; he it was whose guile, +Stirred up with envy and revenge, deceived +The mother of mankind, what time his pride +Had cast him out from Heaven, with all his host +Of rebel Angels, by whose aid, aspiring +To set himself in glory above his peers, +He trusted to have equalled the Most High, +If he opposed, and with ambitious aim +Against the throne and monarchy of God, +Raised impious war in Heaven and battle proud, +With vain attempt. Him the Almighty Power +Hurled headlong flaming from th' ethereal sky, +With hideous ruin and combustion, down +To bottomless perdition, there to dwell +In adamantine chains and penal fire, +Who durst defy th' Omnipotent to arms. + Nine times the space that measures day and night +To mortal men, he, with his horrid crew, +Lay vanquished, rolling in the fiery gulf, +Confounded, though immortal. But his doom +Reserved him to more wrath; for now the thought +Both of lost happiness and lasting pain +Torments him: round he throws his baleful eyes, +That witnessed huge affliction and dismay, +Mixed with obdurate pride and steadfast hate. +At once, as far as Angels ken, he views +The dismal situation waste and wild. +A dungeon horrible, on all sides round, +As one great furnace flamed; yet from those flames +No light; but rather darkness visible +Served only to discover sights of woe, +Regions of sorrow, doleful shades, where peace +And rest can never dwell, hope never comes +That comes to all, but torture without end +Still urges, and a fiery deluge, fed +With ever-burning sulphur unconsumed. +Such place Eternal Justice has prepared +For those rebellious; here their prison ordained +In utter darkness, and their portion set, +As far removed from God and light of Heaven +As from the centre thrice to th' utmost pole. +Oh how unlike the place from whence they fell! +There the companions of his fall, o'erwhelmed +With floods and whirlwinds of tempestuous fire, +He soon discerns; and, weltering by his side, +One next himself in power, and next in crime, +Long after known in Palestine, and named +Beelzebub. To whom th' Arch-Enemy, +And thence in Heaven called Satan, with bold words +Breaking the horrid silence, thus began:-- + "If thou beest he--but O how fallen! how changed +From him who, in the happy realms of light +Clothed with transcendent brightness, didst outshine +Myriads, though bright!--if he whom mutual league, +United thoughts and counsels, equal hope +And hazard in the glorious enterprise +Joined with me once, now misery hath joined +In equal ruin; into what pit thou seest +From what height fallen: so much the stronger proved +He with his thunder; and till then who knew +The force of those dire arms? Yet not for those, +Nor what the potent Victor in his rage +Can else inflict, do I repent, or change, +Though changed in outward lustre, that fixed mind, +And high disdain from sense of injured merit, +That with the Mightiest raised me to contend, +And to the fierce contentions brought along +Innumerable force of Spirits armed, +That durst dislike his reign, and, me preferring, +His utmost power with adverse power opposed +In dubious battle on the plains of Heaven, +And shook his throne. What though the field be lost? +All is not lost--the unconquerable will, +And study of revenge, immortal hate, +And courage never to submit or yield: +And what is else not to be overcome? +That glory never shall his wrath or might +Extort from me. To bow and sue for grace +With suppliant knee, and deify his power +Who, from the terror of this arm, so late +Doubted his empire--that were low indeed; +That were an ignominy and shame beneath +This downfall; since, by fate, the strength of Gods, +And this empyreal sybstance, cannot fail; +Since, through experience of this great event, +In arms not worse, in foresight much advanced, +We may with more successful hope resolve +To wage by force or guile eternal war, +Irreconcilable to our grand Foe, +Who now triumphs, and in th' excess of joy +Sole reigning holds the tyranny of Heaven." + So spake th' apostate Angel, though in pain, +Vaunting aloud, but racked with deep despair; +And him thus answered soon his bold compeer:-- + "O Prince, O Chief of many throned Powers +That led th' embattled Seraphim to war +Under thy conduct, and, in dreadful deeds +Fearless, endangered Heaven's perpetual King, +And put to proof his high supremacy, +Whether upheld by strength, or chance, or fate, +Too well I see and rue the dire event +That, with sad overthrow and foul defeat, +Hath lost us Heaven, and all this mighty host +In horrible destruction laid thus low, +As far as Gods and heavenly Essences +Can perish: for the mind and spirit remains +Invincible, and vigour soon returns, +Though all our glory extinct, and happy state +Here swallowed up in endless misery. +But what if he our Conqueror (whom I now +Of force believe almighty, since no less +Than such could have o'erpowered such force as ours) +Have left us this our spirit and strength entire, +Strongly to suffer and support our pains, +That we may so suffice his vengeful ire, +Or do him mightier service as his thralls +By right of war, whate'er his business be, +Here in the heart of Hell to work in fire, +Or do his errands in the gloomy Deep? +What can it the avail though yet we feel +Strength undiminished, or eternal being +To undergo eternal punishment?" + Whereto with speedy words th' Arch-Fiend replied:-- +"Fallen Cherub, to be weak is miserable, +Doing or suffering: but of this be sure-- +To do aught good never will be our task, +But ever to do ill our sole delight, +As being the contrary to his high will +Whom we resist. If then his providence +Out of our evil seek to bring forth good, +Our labour must be to pervert that end, +And out of good still to find means of evil; +Which ofttimes may succeed so as perhaps +Shall grieve him, if I fail not, and disturb +His inmost counsels from their destined aim. +But see! the angry Victor hath recalled +His ministers of vengeance and pursuit +Back to the gates of Heaven: the sulphurous hail, +Shot after us in storm, o'erblown hath laid +The fiery surge that from the precipice +Of Heaven received us falling; and the thunder, +Winged with red lightning and impetuous rage, +Perhaps hath spent his shafts, and ceases now +To bellow through the vast and boundless Deep. +Let us not slip th' occasion, whether scorn +Or satiate fury yield it from our Foe. +Seest thou yon dreary plain, forlorn and wild, +The seat of desolation, void of light, +Save what the glimmering of these livid flames +Casts pale and dreadful? Thither let us tend +From off the tossing of these fiery waves; +There rest, if any rest can harbour there; +And, re-assembling our afflicted powers, +Consult how we may henceforth most offend +Our enemy, our own loss how repair, +How overcome this dire calamity, +What reinforcement we may gain from hope, +If not, what resolution from despair." + Thus Satan, talking to his nearest mate, +With head uplift above the wave, and eyes +That sparkling blazed; his other parts besides +Prone on the flood, extended long and large, +Lay floating many a rood, in bulk as huge +As whom the fables name of monstrous size, +Titanian or Earth-born, that warred on Jove, +Briareos or Typhon, whom the den +By ancient Tarsus held, or that sea-beast +Leviathan, which God of all his works +Created hugest that swim th' ocean-stream. +Him, haply slumbering on the Norway foam, +The pilot of some small night-foundered skiff, +Deeming some island, oft, as seamen tell, +With fixed anchor in his scaly rind, +Moors by his side under the lee, while night +Invests the sea, and wished morn delays. +So stretched out huge in length the Arch-fiend lay, +Chained on the burning lake; nor ever thence +Had risen, or heaved his head, but that the will +And high permission of all-ruling Heaven +Left him at large to his own dark designs, +That with reiterated crimes he might +Heap on himself damnation, while he sought +Evil to others, and enraged might see +How all his malice served but to bring forth +Infinite goodness, grace, and mercy, shewn +On Man by him seduced, but on himself +Treble confusion, wrath, and vengeance poured. + Forthwith upright he rears from off the pool +His mighty stature; on each hand the flames +Driven backward slope their pointing spires, and,rolled +In billows, leave i' th' midst a horrid vale. +Then with expanded wings he steers his flight +Aloft, incumbent on the dusky air, +That felt unusual weight; till on dry land +He lights--if it were land that ever burned +With solid, as the lake with liquid fire, +And such appeared in hue as when the force +Of subterranean wind transprots a hill +Torn from Pelorus, or the shattered side +Of thundering Etna, whose combustible +And fuelled entrails, thence conceiving fire, +Sublimed with mineral fury, aid the winds, +And leave a singed bottom all involved +With stench and smoke. Such resting found the sole +Of unblest feet. Him followed his next mate; +Both glorying to have scaped the Stygian flood +As gods, and by their own recovered strength, +Not by the sufferance of supernal Power. + "Is this the region, this the soil, the clime," +Said then the lost Archangel, "this the seat +That we must change for Heaven?--this mournful gloom +For that celestial light? Be it so, since he +Who now is sovereign can dispose and bid +What shall be right: farthest from him is best +Whom reason hath equalled, force hath made supreme +Above his equals. Farewell, happy fields, +Where joy for ever dwells! Hail, horrors! hail, +Infernal world! and thou, profoundest Hell, +Receive thy new possessor--one who brings +A mind not to be changed by place or time. +The mind is its own place, and in itself +Can make a Heaven of Hell, a Hell of Heaven. +What matter where, if I be still the same, +And what I should be, all but less than he +Whom thunder hath made greater? Here at least +We shall be free; th' Almighty hath not built +Here for his envy, will not drive us hence: +Here we may reigh secure; and, in my choice, +To reign is worth ambition, though in Hell: +Better to reign in Hell than serve in Heaven. +But wherefore let we then our faithful friends, +Th' associates and co-partners of our loss, +Lie thus astonished on th' oblivious pool, +And call them not to share with us their part +In this unhappy mansion, or once more +With rallied arms to try what may be yet +Regained in Heaven, or what more lost in Hell?" + So Satan spake; and him Beelzebub +Thus answered:--"Leader of those armies bright +Which, but th' Omnipotent, none could have foiled! +If once they hear that voice, their liveliest pledge +Of hope in fears and dangers--heard so oft +In worst extremes, and on the perilous edge +Of battle, when it raged, in all assaults +Their surest signal--they will soon resume +New courage and revive, though now they lie +Grovelling and prostrate on yon lake of fire, +As we erewhile, astounded and amazed; +No wonder, fallen such a pernicious height!" + He scare had ceased when the superior Fiend +Was moving toward the shore; his ponderous shield, +Ethereal temper, massy, large, and round, +Behind him cast. The broad circumference +Hung on his shoulders like the moon, whose orb +Through optic glass the Tuscan artist views +At evening, from the top of Fesole, +Or in Valdarno, to descry new lands, +Rivers, or mountains, in her spotty globe. +His spear--to equal which the tallest pine +Hewn on Norwegian hills, to be the mast +Of some great ammiral, were but a wand-- +He walked with, to support uneasy steps +Over the burning marl, not like those steps +On Heaven's azure; and the torrid clime +Smote on him sore besides, vaulted with fire. +Nathless he so endured, till on the beach +Of that inflamed sea he stood, and called +His legions--Angel Forms, who lay entranced +Thick as autumnal leaves that strow the brooks +In Vallombrosa, where th' Etrurian shades +High over-arched embower; or scattered sedge +Afloat, when with fierce winds Orion armed +Hath vexed the Red-Sea coast, whose waves o'erthrew +Busiris and his Memphian chivalry, +While with perfidious hatred they pursued +The sojourners of Goshen, who beheld +From the safe shore their floating carcases +And broken chariot-wheels. So thick bestrown, +Abject and lost, lay these, covering the flood, +Under amazement of their hideous change. +He called so loud that all the hollow deep +Of Hell resounded:--"Princes, Potentates, +Warriors, the Flower of Heaven--once yours; now lost, +If such astonishment as this can seize +Eternal Spirits! Or have ye chosen this place +After the toil of battle to repose +Your wearied virtue, for the ease you find +To slumber here, as in the vales of Heaven? +Or in this abject posture have ye sworn +To adore the Conqueror, who now beholds +Cherub and Seraph rolling in the flood +With scattered arms and ensigns, till anon +His swift pursuers from Heaven-gates discern +Th' advantage, and, descending, tread us down +Thus drooping, or with linked thunderbolts +Transfix us to the bottom of this gulf? +Awake, arise, or be for ever fallen!" + They heard, and were abashed, and up they sprung +Upon the wing, as when men wont to watch +On duty, sleeping found by whom they dread, +Rouse and bestir themselves ere well awake. +Nor did they not perceive the evil plight +In which they were, or the fierce pains not feel; +Yet to their General's voice they soon obeyed +Innumerable. As when the potent rod +Of Amram's son, in Egypt's evil day, +Waved round the coast, up-called a pitchy cloud +Of locusts, warping on the eastern wind, +That o'er the realm of impious Pharaoh hung +Like Night, and darkened all the land of Nile; +So numberless were those bad Angels seen +Hovering on wing under the cope of Hell, +'Twixt upper, nether, and surrounding fires; +Till, as a signal given, th' uplifted spear +Of their great Sultan waving to direct +Their course, in even balance down they light +On the firm brimstone, and fill all the plain: +A multitude like which the populous North +Poured never from her frozen loins to pass +Rhene or the Danaw, when her barbarous sons +Came like a deluge on the South, and spread +Beneath Gibraltar to the Libyan sands. +Forthwith, form every squadron and each band, +The heads and leaders thither haste where stood +Their great Commander--godlike Shapes, and Forms +Excelling human; princely Dignities; +And Powers that erst in Heaven sat on thrones, +Though on their names in Heavenly records now +Be no memorial, blotted out and rased +By their rebellion from the Books of Life. +Nor had they yet among the sons of Eve +Got them new names, till, wandering o'er the earth, +Through God's high sufferance for the trial of man, +By falsities and lies the greatest part +Of mankind they corrupted to forsake +God their Creator, and th' invisible +Glory of him that made them to transform +Oft to the image of a brute, adorned +With gay religions full of pomp and gold, +And devils to adore for deities: +Then were they known to men by various names, +And various idols through the heathen world. + Say, Muse, their names then known, who first, who last, +Roused from the slumber on that fiery couch, +At their great Emperor's call, as next in worth +Came singly where he stood on the bare strand, +While the promiscuous crowd stood yet aloof? + The chief were those who, from the pit of Hell +Roaming to seek their prey on Earth, durst fix +Their seats, long after, next the seat of God, +Their altars by his altar, gods adored +Among the nations round, and durst abide +Jehovah thundering out of Sion, throned +Between the Cherubim; yea, often placed +Within his sanctuary itself their shrines, +Abominations; and with cursed things +His holy rites and solemn feasts profaned, +And with their darkness durst affront his light. +First, Moloch, horrid king, besmeared with blood +Of human sacrifice, and parents' tears; +Though, for the noise of drums and timbrels loud, +Their children's cries unheard that passed through fire +To his grim idol. Him the Ammonite +Worshiped in Rabba and her watery plain, +In Argob and in Basan, to the stream +Of utmost Arnon. Nor content with such +Audacious neighbourhood, the wisest heart +Of Solomon he led by fraoud to build +His temple right against the temple of God +On that opprobrious hill, and made his grove +The pleasant valley of Hinnom, Tophet thence +And black Gehenna called, the type of Hell. +Next Chemos, th' obscene dread of Moab's sons, +From Aroar to Nebo and the wild +Of southmost Abarim; in Hesebon +And Horonaim, Seon's real, beyond +The flowery dale of Sibma clad with vines, +And Eleale to th' Asphaltic Pool: +Peor his other name, when he enticed +Israel in Sittim, on their march from Nile, +To do him wanton rites, which cost them woe. +Yet thence his lustful orgies he enlarged +Even to that hill of scandal, by the grove +Of Moloch homicide, lust hard by hate, +Till good Josiah drove them thence to Hell. +With these came they who, from the bordering flood +Of old Euphrates to the brook that parts +Egypt from Syrian ground, had general names +Of Baalim and Ashtaroth--those male, +These feminine. For Spirits, when they please, +Can either sex assume, or both; so soft +And uncompounded is their essence pure, +Not tried or manacled with joint or limb, +Nor founded on the brittle strength of bones, +Like cumbrous flesh; but, in what shape they choose, +Dilated or condensed, bright or obscure, +Can execute their airy purposes, +And works of love or enmity fulfil. +For those the race of Israel oft forsook +Their Living Strength, and unfrequented left +His righteous altar, bowing lowly down +To bestial gods; for which their heads as low +Bowed down in battle, sunk before the spear +Of despicable foes. With these in troop +Came Astoreth, whom the Phoenicians called +Astarte, queen of heaven, with crescent horns; +To whose bright image nigntly by the moon +Sidonian virgins paid their vows and songs; +In Sion also not unsung, where stood +Her temple on th' offensive mountain, built +By that uxorious king whose heart, though large, +Beguiled by fair idolatresses, fell +To idols foul. Thammuz came next behind, +Whose annual wound in Lebanon allured +The Syrian damsels to lament his fate +In amorous ditties all a summer's day, +While smooth Adonis from his native rock +Ran purple to the sea, supposed with blood +Of Thammuz yearly wounded: the love-tale +Infected Sion's daughters with like heat, +Whose wanton passions in the sacred proch +Ezekiel saw, when, by the vision led, +His eye surveyed the dark idolatries +Of alienated Judah. Next came one +Who mourned in earnest, when the captive ark +Maimed his brute image, head and hands lopt off, +In his own temple, on the grunsel-edge, +Where he fell flat and shamed his worshippers: +Dagon his name, sea-monster,upward man +And downward fish; yet had his temple high +Reared in Azotus, dreaded through the coast +Of Palestine, in Gath and Ascalon, +And Accaron and Gaza's frontier bounds. +Him followed Rimmon, whose delightful seat +Was fair Damascus, on the fertile banks +Of Abbana and Pharphar, lucid streams. +He also against the house of God was bold: +A leper once he lost, and gained a king-- +Ahaz, his sottish conqueror, whom he drew +God's altar to disparage and displace +For one of Syrian mode, whereon to burn +His odious offerings, and adore the gods +Whom he had vanquished. After these appeared +A crew who, under names of old renown-- +Osiris, Isis, Orus, and their train-- +With monstrous shapes and sorceries abused +Fanatic Egypt and her priests to seek +Their wandering gods disguised in brutish forms +Rather than human. Nor did Israel scape +Th' infection, when their borrowed gold composed +The calf in Oreb; and the rebel king +Doubled that sin in Bethel and in Dan, +Likening his Maker to the grazed ox-- +Jehovah, who, in one night, when he passed +From Egypt marching, equalled with one stroke +Both her first-born and all her bleating gods. +Belial came last; than whom a Spirit more lewd +Fell not from Heaven, or more gross to love +Vice for itself. To him no temple stood +Or altar smoked; yet who more oft than he +In temples and at altars, when the priest +Turns atheist, as did Eli's sons, who filled +With lust and violence the house of God? +In courts and palaces he also reigns, +And in luxurious cities, where the noise +Of riot ascends above their loftiest towers, +And injury and outrage; and, when night +Darkens the streets, then wander forth the sons +Of Belial, flown with insolence and wine. +Witness the streets of Sodom, and that night +In Gibeah, when the hospitable door +Exposed a matron, to avoid worse rape. + These were the prime in order and in might: +The rest were long to tell; though far renowned +Th' Ionian gods--of Javan's issue held +Gods, yet confessed later than Heaven and Earth, +Their boasted parents;--Titan, Heaven's first-born, +With his enormous brood, and birthright seized +By younger Saturn: he from mightier Jove, +His own and Rhea's son, like measure found; +So Jove usurping reigned. These, first in Crete +And Ida known, thence on the snowy top +Of cold Olympus ruled the middle air, +Their highest heaven; or on the Delphian cliff, +Or in Dodona, and through all the bounds +Of Doric land; or who with Saturn old +Fled over Adria to th' Hesperian fields, +And o'er the Celtic roamed the utmost Isles. + All these and more came flocking; but with looks +Downcast and damp; yet such wherein appeared +Obscure some glimpse of joy to have found their Chief +Not in despair, to have found themselves not lost +In loss itself; which on his countenance cast +Like doubtful hue. But he, his wonted pride +Soon recollecting, with high words, that bore +Semblance of worth, not substance, gently raised +Their fainting courage, and dispelled their fears. +Then straight commands that, at the warlike sound +Of trumpets loud and clarions, be upreared +His mighty standard. That proud honour claimed +Azazel as his right, a Cherub tall: +Who forthwith from the glittering staff unfurled +Th' imperial ensign; which, full high advanced, +Shone like a meteor streaming to the wind, +With gems and golden lustre rich emblazed, +Seraphic arms and trophies; all the while +Sonorous metal blowing martial sounds: +At which the universal host up-sent +A shout that tore Hell's concave, and beyond +Frighted the reign of Chaos and old Night. +All in a moment through the gloom were seen +Ten thousand banners rise into the air, +With orient colours waving: with them rose +A forest huge of spears; and thronging helms +Appeared, and serried shields in thick array +Of depth immeasurable. Anon they move +In perfect phalanx to the Dorian mood +Of flutes and soft recorders--such as raised +To height of noblest temper heroes old +Arming to battle, and instead of rage +Deliberate valour breathed, firm, and unmoved +With dread of death to flight or foul retreat; +Nor wanting power to mitigate and swage +With solemn touches troubled thoughts, and chase +Anguish and doubt and fear and sorrow and pain +From mortal or immortal minds. Thus they, +Breathing united force with fixed thought, +Moved on in silence to soft pipes that charmed +Their painful steps o'er the burnt soil. And now +Advanced in view they stand--a horrid front +Of dreadful length and dazzling arms, in guise +Of warriors old, with ordered spear and shield, +Awaiting what command their mighty Chief +Had to impose. He through the armed files +Darts his experienced eye, and soon traverse +The whole battalion views--their order due, +Their visages and stature as of gods; +Their number last he sums. And now his heart +Distends with pride, and, hardening in his strength, +Glories: for never, since created Man, +Met such embodied force as, named with these, +Could merit more than that small infantry +Warred on by cranes--though all the giant brood +Of Phlegra with th' heroic race were joined +That fought at Thebes and Ilium, on each side +Mixed with auxiliar gods; and what resounds +In fable or romance of Uther's son, +Begirt with British and Armoric knights; +And all who since, baptized or infidel, +Jousted in Aspramont, or Montalban, +Damasco, or Marocco, or Trebisond, +Or whom Biserta sent from Afric shore +When Charlemain with all his peerage fell +By Fontarabbia. Thus far these beyond +Compare of mortal prowess, yet observed +Their dread Commander. He, above the rest +In shape and gesture proudly eminent, +Stood like a tower. His form had yet not lost +All her original brightness, nor appeared +Less than Archangel ruined, and th' excess +Of glory obscured: as when the sun new-risen +Looks through the horizontal misty air +Shorn of his beams, or, from behind the moon, +In dim eclipse, disastrous twilight sheds +On half the nations, and with fear of change +Perplexes monarchs. Darkened so, yet shone +Above them all th' Archangel: but his face +Deep scars of thunder had intrenched, and care +Sat on his faded cheek, but under brows +Of dauntless courage, and considerate pride +Waiting revenge. Cruel his eye, but cast +Signs of remorse and passion, to behold +The fellows of his crime, the followers rather +(Far other once beheld in bliss), condemned +For ever now to have their lot in pain-- +Millions of Spirits for his fault amerced +Of Heaven, and from eteranl splendours flung +For his revolt--yet faithful how they stood, +Their glory withered; as, when heaven's fire +Hath scathed the forest oaks or mountain pines, +With singed top their stately growth, though bare, +Stands on the blasted heath. He now prepared +To speak; whereat their doubled ranks they bend +From wing to wing, and half enclose him round +With all his peers: attention held them mute. +Thrice he assayed, and thrice, in spite of scorn, +Tears, such as Angels weep, burst forth: at last +Words interwove with sighs found out their way:-- + "O myriads of immortal Spirits! O Powers +Matchless, but with th' Almighth!--and that strife +Was not inglorious, though th' event was dire, +As this place testifies, and this dire change, +Hateful to utter. But what power of mind, +Forseeing or presaging, from the depth +Of knowledge past or present, could have feared +How such united force of gods, how such +As stood like these, could ever know repulse? +For who can yet believe, though after loss, +That all these puissant legions, whose exile +Hath emptied Heaven, shall fail to re-ascend, +Self-raised, and repossess their native seat? +For me, be witness all the host of Heaven, +If counsels different, or danger shunned +By me, have lost our hopes. But he who reigns +Monarch in Heaven till then as one secure +Sat on his throne, upheld by old repute, +Consent or custom, and his regal state +Put forth at full, but still his strength concealed-- +Which tempted our attempt, and wrought our fall. +Henceforth his might we know, and know our own, +So as not either to provoke, or dread +New war provoked: our better part remains +To work in close design, by fraud or guile, +What force effected not; that he no less +At length from us may find, who overcomes +By force hath overcome but half his foe. +Space may produce new Worlds; whereof so rife +There went a fame in Heaven that he ere long +Intended to create, and therein plant +A generation whom his choice regard +Should favour equal to the Sons of Heaven. +Thither, if but to pry, shall be perhaps +Our first eruption--thither, or elsewhere; +For this infernal pit shall never hold +Celestial Spirits in bondage, nor th' Abyss +Long under darkness cover. But these thoughts +Full counsel must mature. Peace is despaired; +For who can think submission? War, then, war +Open or understood, must be resolved." + He spake; and, to confirm his words, outflew +Millions of flaming swords, drawn from the thighs +Of mighty Cherubim; the sudden blaze +Far round illumined Hell. Highly they raged +Against the Highest, and fierce with grasped arms +Clashed on their sounding shields the din of war, +Hurling defiance toward the vault of Heaven. + There stood a hill not far, whose grisly top +Belched fire and rolling smoke; the rest entire +Shone with a glossy scurf--undoubted sign +That in his womb was hid metallic ore, +The work of sulphur. Thither, winged with speed, +A numerous brigade hastened: as when bands +Of pioneers, with spade and pickaxe armed, +Forerun the royal camp, to trench a field, +Or cast a rampart. Mammon led them on-- +Mammon, the least erected Spirit that fell +From Heaven; for even in Heaven his looks and thoughts +Were always downward bent, admiring more +The riches of heaven's pavement, trodden gold, +Than aught divine or holy else enjoyed +In vision beatific. By him first +Men also, and by his suggestion taught, +Ransacked the centre, and with impious hands +Rifled the bowels of their mother Earth +For treasures better hid. Soon had his crew +Opened into the hill a spacious wound, +And digged out ribs of gold. Let none admire +That riches grow in Hell; that soil may best +Deserve the precious bane. And here let those +Who boast in mortal things, and wondering tell +Of Babel, and the works of Memphian kings, +Learn how their greatest monuments of fame +And strength, and art, are easily outdone +By Spirits reprobate, and in an hour +What in an age they, with incessant toil +And hands innumerable, scarce perform. +Nigh on the plain, in many cells prepared, +That underneath had veins of liquid fire +Sluiced from the lake, a second multitude +With wondrous art founded the massy ore, +Severing each kind, and scummed the bullion-dross. +A third as soon had formed within the ground +A various mould, and from the boiling cells +By strange conveyance filled each hollow nook; +As in an organ, from one blast of wind, +To many a row of pipes the sound-board breathes. +Anon out of the earth a fabric huge +Rose like an exhalation, with the sound +Of dulcet symphonies and voices sweet-- +Built like a temple, where pilasters round +Were set, and Doric pillars overlaid +With golden architrave; nor did there want +Cornice or frieze, with bossy sculptures graven; +The roof was fretted gold. Not Babylon +Nor great Alcairo such magnificence +Equalled in all their glories, to enshrine +Belus or Serapis their gods, or seat +Their kings, when Egypt with Assyria strove +In wealth and luxury. Th' ascending pile +Stood fixed her stately height, and straight the doors, +Opening their brazen folds, discover, wide +Within, her ample spaces o'er the smooth +And level pavement: from the arched roof, +Pendent by subtle magic, many a row +Of starry lamps and blazing cressets, fed +With naptha and asphaltus, yielded light +As from a sky. The hasty multitude +Admiring entered; and the work some praise, +And some the architect. His hand was known +In Heaven by many a towered structure high, +Where sceptred Angels held their residence, +And sat as Princes, whom the supreme King +Exalted to such power, and gave to rule, +Each in his Hierarchy, the Orders bright. +Nor was his name unheard or unadored +In ancient Greece; and in Ausonian land +Men called him Mulciber; and how he fell +From Heaven they fabled, thrown by angry Jove +Sheer o'er the crystal battlements: from morn +To noon he fell, from noon to dewy eve, +A summer's day, and with the setting sun +Dropt from the zenith, like a falling star, +On Lemnos, th' Aegaean isle. Thus they relate, +Erring; for he with this rebellious rout +Fell long before; nor aught aviled him now +To have built in Heaven high towers; nor did he scape +By all his engines, but was headlong sent, +With his industrious crew, to build in Hell. + Meanwhile the winged Heralds, by command +Of sovereign power, with awful ceremony +And trumpet's sound, throughout the host proclaim +A solemn council forthwith to be held +At Pandemonium, the high capital +Of Satan and his peers. Their summons called +From every band and squared regiment +By place or choice the worthiest: they anon +With hundreds and with thousands trooping came +Attended. All access was thronged; the gates +And porches wide, but chief the spacious hall +(Though like a covered field, where champions bold +Wont ride in armed, and at the Soldan's chair +Defied the best of Paynim chivalry +To mortal combat, or career with lance), +Thick swarmed, both on the ground and in the air, +Brushed with the hiss of rustling wings. As bees +In spring-time, when the Sun with Taurus rides. +Pour forth their populous youth about the hive +In clusters; they among fresh dews and flowers +Fly to and fro, or on the smoothed plank, +The suburb of their straw-built citadel, +New rubbed with balm, expatiate, and confer +Their state-affairs: so thick the airy crowd +Swarmed and were straitened; till, the signal given, +Behold a wonder! They but now who seemed +In bigness to surpass Earth's giant sons, +Now less than smallest dwarfs, in narrow room +Throng numberless--like that pygmean race +Beyond the Indian mount; or faery elves, +Whose midnight revels, by a forest-side +Or fountain, some belated peasant sees, +Or dreams he sees, while overhead the Moon +Sits arbitress, and nearer to the Earth +Wheels her pale course: they, on their mirth and dance +Intent, with jocund music charm his ear; +At once with joy and fear his heart rebounds. +Thus incorporeal Spirits to smallest forms +Reduced their shapes immense, and were at large, +Though without number still, amidst the hall +Of that infernal court. But far within, +And in their own dimensions like themselves, +The great Seraphic Lords and Cherubim +In close recess and secret conclave sat, +A thousand demi-gods on golden seats, +Frequent and full. After short silence then, +And summons read, the great consult began. + + + +Book II + + +High on a throne of royal state, which far +Outshone the wealth or Ormus and of Ind, +Or where the gorgeous East with richest hand +Showers on her kings barbaric pearl and gold, +Satan exalted sat, by merit raised +To that bad eminence; and, from despair +Thus high uplifted beyond hope, aspires +Beyond thus high, insatiate to pursue +Vain war with Heaven; and, by success untaught, +His proud imaginations thus displayed:-- + "Powers and Dominions, Deities of Heaven!-- +For, since no deep within her gulf can hold +Immortal vigour, though oppressed and fallen, +I give not Heaven for lost: from this descent +Celestial Virtues rising will appear +More glorious and more dread than from no fall, +And trust themselves to fear no second fate!-- +Me though just right, and the fixed laws of Heaven, +Did first create your leader--next, free choice +With what besides in council or in fight +Hath been achieved of merit--yet this loss, +Thus far at least recovered, hath much more +Established in a safe, unenvied throne, +Yielded with full consent. The happier state +In Heaven, which follows dignity, might draw +Envy from each inferior; but who here +Will envy whom the highest place exposes +Foremost to stand against the Thunderer's aim +Your bulwark, and condemns to greatest share +Of endless pain? Where there is, then, no good +For which to strive, no strife can grow up there +From faction: for none sure will claim in Hell +Precedence; none whose portion is so small +Of present pain that with ambitious mind +Will covet more! With this advantage, then, +To union, and firm faith, and firm accord, +More than can be in Heaven, we now return +To claim our just inheritance of old, +Surer to prosper than prosperity +Could have assured us; and by what best way, +Whether of open war or covert guile, +We now debate. Who can advise may speak." + He ceased; and next him Moloch, sceptred king, +Stood up--the strongest and the fiercest Spirit +That fought in Heaven, now fiercer by despair. +His trust was with th' Eternal to be deemed +Equal in strength, and rather than be less +Cared not to be at all; with that care lost +Went all his fear: of God, or Hell, or worse, +He recked not, and these words thereafter spake:-- + "My sentence is for open war. Of wiles, +More unexpert, I boast not: them let those +Contrive who need, or when they need; not now. +For, while they sit contriving, shall the rest-- +Millions that stand in arms, and longing wait +The signal to ascend--sit lingering here, +Heaven's fugitives, and for their dwelling-place +Accept this dark opprobrious den of shame, +The prison of his ryranny who reigns +By our delay? No! let us rather choose, +Armed with Hell-flames and fury, all at once +O'er Heaven's high towers to force resistless way, +Turning our tortures into horrid arms +Against the Torturer; when, to meet the noise +Of his almighty engine, he shall hear +Infernal thunder, and, for lightning, see +Black fire and horror shot with equal rage +Among his Angels, and his throne itself +Mixed with Tartarean sulphur and strange fire, +His own invented torments. But perhaps +The way seems difficult, and steep to scale +With upright wing against a higher foe! +Let such bethink them, if the sleepy drench +Of that forgetful lake benumb not still, +That in our porper motion we ascend +Up to our native seat; descent and fall +To us is adverse. Who but felt of late, +When the fierce foe hung on our broken rear +Insulting, and pursued us through the Deep, +With what compulsion and laborious flight +We sunk thus low? Th' ascent is easy, then; +Th' event is feared! Should we again provoke +Our stronger, some worse way his wrath may find +To our destruction, if there be in Hell +Fear to be worse destroyed! What can be worse +Than to dwell here, driven out from bliss, condemned +In this abhorred deep to utter woe! +Where pain of unextinguishable fire +Must exercise us without hope of end +The vassals of his anger, when the scourge +Inexorably, and the torturing hour, +Calls us to penance? More destroyed than thus, +We should be quite abolished, and expire. +What fear we then? what doubt we to incense +His utmost ire? which, to the height enraged, +Will either quite consume us, and reduce +To nothing this essential--happier far +Than miserable to have eternal being!-- +Or, if our substance be indeed divine, +And cannot cease to be, we are at worst +On this side nothing; and by proof we feel +Our power sufficient to disturb his Heaven, +And with perpetual inroads to alarm, +Though inaccessible, his fatal throne: +Which, if not victory, is yet revenge." + He ended frowning, and his look denounced +Desperate revenge, and battle dangerous +To less than gods. On th' other side up rose +Belial, in act more graceful and humane. +A fairer person lost not Heaven; he seemed +For dignity composed, and high exploit. +But all was false and hollow; though his tongue +Dropped manna, and could make the worse appear +The better reason, to perplex and dash +Maturest counsels: for his thoughts were low-- + To vice industrious, but to nobler deeds +Timorous and slothful. Yet he pleased the ear, +And with persuasive accent thus began:-- + "I should be much for open war, O Peers, +As not behind in hate, if what was urged +Main reason to persuade immediate war +Did not dissuade me most, and seem to cast +Ominous conjecture on the whole success; +When he who most excels in fact of arms, +In what he counsels and in what excels +Mistrustful, grounds his courage on despair +And utter dissolution, as the scope +Of all his aim, after some dire revenge. +First, what revenge? The towers of Heaven are filled +With armed watch, that render all access +Impregnable: oft on the bodering Deep +Encamp their legions, or with obscure wing +Scout far and wide into the realm of Night, +Scorning surprise. Or, could we break our way +By force, and at our heels all Hell should rise +With blackest insurrection to confound +Heaven's purest light, yet our great Enemy, +All incorruptible, would on his throne +Sit unpolluted, and th' ethereal mould, +Incapable of stain, would soon expel +Her mischief, and purge off the baser fire, +Victorious. Thus repulsed, our final hope +Is flat despair: we must exasperate +Th' Almighty Victor to spend all his rage; +And that must end us; that must be our cure-- +To be no more. Sad cure! for who would lose, +Though full of pain, this intellectual being, +Those thoughts that wander through eternity, +To perish rather, swallowed up and lost +In the wide womb of uncreated Night, +Devoid of sense and motion? And who knows, +Let this be good, whether our angry Foe +Can give it, or will ever? How he can +Is doubtful; that he never will is sure. +Will he, so wise, let loose at once his ire, +Belike through impotence or unaware, +To give his enemies their wish, and end +Them in his anger whom his anger saves +To punish endless? 'Wherefore cease we, then?' +Say they who counsel war; 'we are decreed, +Reserved, and destined to eternal woe; +Whatever doing, what can we suffer more, +What can we suffer worse?' Is this, then, worst-- +Thus sitting, thus consulting, thus in arms? +What when we fled amain, pursued and struck +With Heaven's afflicting thunder, and besought +The Deep to shelter us? This Hell then seemed +A refuge from those wounds. Or when we lay +Chained on the burning lake? That sure was worse. +What if the breath that kindled those grim fires, +Awaked, should blow them into sevenfold rage, +And plunge us in the flames; or from above +Should intermitted vengeance arm again +His red right hand to plague us? What if all +Her stores were opened, and this firmament +Of Hell should spout her cataracts of fire, +Impendent horrors, threatening hideous fall +One day upon our heads; while we perhaps, +Designing or exhorting glorious war, +Caught in a fiery tempest, shall be hurled, +Each on his rock transfixed, the sport and prey +Or racking whirlwinds, or for ever sunk +Under yon boiling ocean, wrapt in chains, +There to converse with everlasting groans, +Unrespited, unpitied, unreprieved, +Ages of hopeless end? This would be worse. +War, therefore, open or concealed, alike +My voice dissuades; for what can force or guile +With him, or who deceive his mind, whose eye +Views all things at one view? He from Heaven's height +All these our motions vain sees and derides, +Not more almighty to resist our might +Than wise to frustrate all our plots and wiles. +Shall we, then, live thus vile--the race of Heaven +Thus trampled, thus expelled, to suffer here +Chains and these torments? Better these than worse, +By my advice; since fate inevitable +Subdues us, and omnipotent decree, +The Victor's will. To suffer, as to do, +Our strength is equal; nor the law unjust +That so ordains. This was at first resolved, +If we were wise, against so great a foe +Contending, and so doubtful what might fall. +I laugh when those who at the spear are bold +And venturous, if that fail them, shrink, and fear +What yet they know must follow--to endure +Exile, or igominy, or bonds, or pain, +The sentence of their Conqueror. This is now +Our doom; which if we can sustain and bear, +Our Supreme Foe in time may much remit +His anger, and perhaps, thus far removed, +Not mind us not offending, satisfied +With what is punished; whence these raging fires +Will slacken, if his breath stir not their flames. +Our purer essence then will overcome +Their noxious vapour; or, inured, not feel; +Or, changed at length, and to the place conformed +In temper and in nature, will receive +Familiar the fierce heat; and, void of pain, +This horror will grow mild, this darkness light; +Besides what hope the never-ending flight +Of future days may bring, what chance, what change +Worth waiting--since our present lot appears +For happy though but ill, for ill not worst, +If we procure not to ourselves more woe." + Thus Belial, with words clothed in reason's garb, +Counselled ignoble ease and peaceful sloth, +Not peace; and after him thus Mammon spake:-- + "Either to disenthrone the King of Heaven +We war, if war be best, or to regain +Our own right lost. Him to unthrone we then +May hope, when everlasting Fate shall yield +To fickle Chance, and Chaos judge the strife. +The former, vain to hope, argues as vain +The latter; for what place can be for us +Within Heaven's bound, unless Heaven's Lord supreme +We overpower? Suppose he should relent +And publish grace to all, on promise made +Of new subjection; with what eyes could we +Stand in his presence humble, and receive +Strict laws imposed, to celebrate his throne +With warbled hyms, and to his Godhead sing +Forced hallelujahs, while he lordly sits +Our envied sovereign, and his altar breathes +Ambrosial odours and ambrosial flowers, +Our servile offerings? This must be our task +In Heaven, this our delight. How wearisome +Eternity so spent in worship paid +To whom we hate! Let us not then pursue, +By force impossible, by leave obtained +Unacceptable, though in Heaven, our state +Of splendid vassalage; but rather seek +Our own good from ourselves, and from our own +Live to ourselves, though in this vast recess, +Free and to none accountable, preferring +Hard liberty before the easy yoke +Of servile pomp. Our greatness will appear +Then most conspicuous when great things of small, +Useful of hurtful, prosperous of adverse, +We can create, and in what place soe'er +Thrive under evil, and work ease out of pain +Through labour and endurance. This deep world +Of darkness do we dread? How oft amidst +Thick clouds and dark doth Heaven's all-ruling Sire +Choose to reside, his glory unobscured, +And with the majesty of darkness round +Covers his throne, from whence deep thunders roar. +Mustering their rage, and Heaven resembles Hell! +As he our darkness, cannot we his light +Imitate when we please? This desert soil +Wants not her hidden lustre, gems and gold; +Nor want we skill or art from whence to raise +Magnificence; and what can Heaven show more? +Our torments also may, in length of time, +Become our elements, these piercing fires +As soft as now severe, our temper changed +Into their temper; which must needs remove +The sensible of pain. All things invite +To peaceful counsels, and the settled state +Of order, how in safety best we may +Compose our present evils, with regard +Of what we are and where, dismissing quite +All thoughts of war. Ye have what I advise." + He scarce had finished, when such murmur filled +Th' assembly as when hollow rocks retain +The sound of blustering winds, which all night long +Had roused the sea, now with hoarse cadence lull +Seafaring men o'erwatched, whose bark by chance +Or pinnace, anchors in a craggy bay +After the tempest. Such applause was heard +As Mammon ended, and his sentence pleased, +Advising peace: for such another field +They dreaded worse than Hell; so much the fear +Of thunder and the sword of Michael +Wrought still within them; and no less desire +To found this nether empire, which might rise, +By policy and long process of time, +In emulation opposite to Heaven. +Which when Beelzebub perceived--than whom, +Satan except, none higher sat--with grave +Aspect he rose, and in his rising seemed +A pillar of state. Deep on his front engraven +Deliberation sat, and public care; +And princely counsel in his face yet shone, +Majestic, though in ruin. Sage he stood +With Atlantean shoulders, fit to bear +The weight of mightiest monarchies; his look +Drew audience and attention still as night +Or summer's noontide air, while thus he spake:-- + "Thrones and Imperial Powers, Offspring of Heaven, +Ethereal Virtues! or these titles now +Must we renounce, and, changing style, be called +Princes of Hell? for so the popular vote +Inclines--here to continue, and build up here +A growing empire; doubtless! while we dream, +And know not that the King of Heaven hath doomed +This place our dungeon, not our safe retreat +Beyond his potent arm, to live exempt +From Heaven's high jurisdiction, in new league +Banded against his throne, but to remain +In strictest bondage, though thus far removed, +Under th' inevitable curb, reserved +His captive multitude. For he, to be sure, +In height or depth, still first and last will reign +Sole king, and of his kingdom lose no part +By our revolt, but over Hell extend +His empire, and with iron sceptre rule +Us here, as with his golden those in Heaven. +What sit we then projecting peace and war? +War hath determined us and foiled with loss +Irreparable; terms of peace yet none +Vouchsafed or sought; for what peace will be given +To us enslaved, but custody severe, +And stripes and arbitrary punishment +Inflicted? and what peace can we return, +But, to our power, hostility and hate, +Untamed reluctance, and revenge, though slow, +Yet ever plotting how the Conqueror least +May reap his conquest, and may least rejoice +In doing what we most in suffering feel? +Nor will occasion want, nor shall we need +With dangerous expedition to invade +Heaven, whose high walls fear no assault or siege, +Or ambush from the Deep. What if we find +Some easier enterprise? There is a place +(If ancient and prophetic fame in Heaven +Err not)--another World, the happy seat +Of some new race, called Man, about this time +To be created like to us, though less +In power and excellence, but favoured more +Of him who rules above; so was his will +Pronounced among the Gods, and by an oath +That shook Heaven's whole circumference confirmed. +Thither let us bend all our thoughts, to learn +What creatures there inhabit, of what mould +Or substance, how endued, and what their power +And where their weakness: how attempted best, +By force of subtlety. Though Heaven be shut, +And Heaven's high Arbitrator sit secure +In his own strength, this place may lie exposed, +The utmost border of his kingdom, left +To their defence who hold it: here, perhaps, +Some advantageous act may be achieved +By sudden onset--either with Hell-fire +To waste his whole creation, or possess +All as our own, and drive, as we were driven, +The puny habitants; or, if not drive, +Seduce them to our party, that their God +May prove their foe, and with repenting hand +Abolish his own works. This would surpass +Common revenge, and interrupt his joy +In our confusion, and our joy upraise +In his disturbance; when his darling sons, +Hurled headlong to partake with us, shall curse +Their frail original, and faded bliss-- +Faded so soon! Advise if this be worth +Attempting, or to sit in darkness here +Hatching vain empires." Thus beelzebub +Pleaded his devilish counsel--first devised +By Satan, and in part proposed: for whence, +But from the author of all ill, could spring +So deep a malice, to confound the race +Of mankind in one root, and Earth with Hell +To mingle and involve, done all to spite +The great Creator? But their spite still serves +His glory to augment. The bold design +Pleased highly those infernal States, and joy +Sparkled in all their eyes: with full assent +They vote: whereat his speech he thus renews:-- +"Well have ye judged, well ended long debate, +Synod of Gods, and, like to what ye are, +Great things resolved, which from the lowest deep +Will once more lift us up, in spite of fate, +Nearer our ancient seat--perhaps in view +Of those bright confines, whence, with neighbouring arms, +And opportune excursion, we may chance +Re-enter Heaven; or else in some mild zone +Dwell, not unvisited of Heaven's fair light, +Secure, and at the brightening orient beam +Purge off this gloom: the soft delicious air, +To heal the scar of these corrosive fires, +Shall breathe her balm. But, first, whom shall we send +In search of this new World? whom shall we find +Sufficient? who shall tempt with wandering feet +The dark, unbottomed, infinite Abyss, +And through the palpable obscure find out +His uncouth way, or spread his airy flight, +Upborne with indefatigable wings +Over the vast abrupt, ere he arrive +The happy Isle? What strength, what art, can then +Suffice, or what evasion bear him safe, +Through the strict senteries and stations thick +Of Angels watching round? Here he had need +All circumspection: and we now no less +Choice in our suffrage; for on whom we send +The weight of all, and our last hope, relies." + This said, he sat; and expectation held +His look suspense, awaiting who appeared +To second, or oppose, or undertake +The perilous attempt. But all sat mute, +Pondering the danger with deep thoughts; and each +In other's countenance read his own dismay, +Astonished. None among the choice and prime +Of those Heaven-warring champions could be found +So hardy as to proffer or accept, +Alone, the dreadful voyage; till, at last, +Satan, whom now transcendent glory raised +Above his fellows, with monarchal pride +Conscious of highest worth, unmoved thus spake:-- + "O Progeny of Heaven! Empyreal Thrones! +With reason hath deep silence and demur +Seized us, though undismayed. Long is the way +And hard, that out of Hell leads up to light. +Our prison strong, this huge convex of fire, +Outrageous to devour, immures us round +Ninefold; and gates of burning adamant, +Barred over us, prohibit all egress. +These passed, if any pass, the void profound +Of unessential Night receives him next, +Wide-gaping, and with utter loss of being +Threatens him, plunged in that abortive gulf. +If thence he scape, into whatever world, +Or unknown region, what remains him less +Than unknown dangers, and as hard escape? +But I should ill become this throne, O Peers, +And this imperial sovereignty, adorned +With splendour, armed with power, if aught proposed +And judged of public moment in the shape +Of difficulty or danger, could deter +Me from attempting. Wherefore do I assume +These royalties, and not refuse to reign, +Refusing to accept as great a share +Of hazard as of honour, due alike +To him who reigns, and so much to him due +Of hazard more as he above the rest +High honoured sits? Go, therefore, mighty Powers, +Terror of Heaven, though fallen; intend at home, +While here shall be our home, what best may ease +The present misery, and render Hell +More tolerable; if there be cure or charm +To respite, or deceive, or slack the pain +Of this ill mansion: intermit no watch +Against a wakeful foe, while I abroad +Through all the coasts of dark destruction seek +Deliverance for us all. This enterprise +None shall partake with me." Thus saying, rose +The Monarch, and prevented all reply; +Prudent lest, from his resolution raised, +Others among the chief might offer now, +Certain to be refused, what erst they feared, +And, so refused, might in opinion stand +His rivals, winning cheap the high repute +Which he through hazard huge must earn. But they +Dreaded not more th' adventure than his voice +Forbidding; and at once with him they rose. +Their rising all at once was as the sound +Of thunder heard remote. Towards him they bend +With awful reverence prone, and as a God +Extol him equal to the Highest in Heaven. +Nor failed they to express how much they praised +That for the general safety he despised +His own: for neither do the Spirits damned +Lose all their virtue; lest bad men should boast +Their specious deeds on earth, which glory excites, +Or close ambition varnished o'er with zeal. + Thus they their doubtful consultations dark +Ended, rejoicing in their matchless Chief: +As, when from mountain-tops the dusky clouds +Ascending, while the north wind sleeps, o'erspread +Heaven's cheerful face, the louring element +Scowls o'er the darkened landscape snow or shower, +If chance the radiant sun, with farewell sweet, +Extend his evening beam, the fields revive, +The birds their notes renew, and bleating herds +Attest their joy, that hill and valley rings. +O shame to men! Devil with devil damned +Firm concord holds; men only disagree +Of creatures rational, though under hope +Of heavenly grace, and, God proclaiming peace, +Yet live in hatred, enmity, and strife +Among themselves, and levy cruel wars +Wasting the earth, each other to destroy: +As if (which might induce us to accord) +Man had not hellish foes enow besides, +That day and night for his destruction wait! + The Stygian council thus dissolved; and forth +In order came the grand infernal Peers: +Midst came their mighty Paramount, and seemed +Alone th' antagonist of Heaven, nor less +Than Hell's dread Emperor, with pomp supreme, +And god-like imitated state: him round +A globe of fiery Seraphim enclosed +With bright emblazonry, and horrent arms. +Then of their session ended they bid cry +With trumpet's regal sound the great result: +Toward the four winds four speedy Cherubim +Put to their mouths the sounding alchemy, +By herald's voice explained; the hollow Abyss +Heard far adn wide, and all the host of Hell +With deafening shout returned them loud acclaim. +Thence more at ease their minds, and somewhat raised +By false presumptuous hope, the ranged Powers +Disband; and, wandering, each his several way +Pursues, as inclination or sad choice +Leads him perplexed, where he may likeliest find +Truce to his restless thoughts, and entertain +The irksome hours, till his great Chief return. +Part on the plain, or in the air sublime, +Upon the wing or in swift race contend, +As at th' Olympian games or Pythian fields; +Part curb their fiery steeds, or shun the goal +With rapid wheels, or fronted brigades form: +As when, to warn proud cities, war appears +Waged in the troubled sky, and armies rush +To battle in the clouds; before each van +Prick forth the airy knights, and couch their spears, +Till thickest legions close; with feats of arms +From either end of heaven the welkin burns. +Others, with vast Typhoean rage, more fell, +Rend up both rocks and hills, and ride the air +In whirlwind; Hell scarce holds the wild uproar:-- +As when Alcides, from Oechalia crowned +With conquest, felt th' envenomed robe, and tore +Through pain up by the roots Thessalian pines, +And Lichas from the top of Oeta threw +Into th' Euboic sea. Others, more mild, +Retreated in a silent valley, sing +With notes angelical to many a harp +Their own heroic deeds, and hapless fall +By doom of battle, and complain that Fate +Free Virtue should enthrall to Force or Chance. +Their song was partial; but the harmony +(What could it less when Spirits immortal sing?) +Suspended Hell, and took with ravishment +The thronging audience. In discourse more sweet +(For Eloquence the Soul, Song charms the Sense) +Others apart sat on a hill retired, +In thoughts more elevate, and reasoned high +Of Providence, Foreknowledge, Will, and Fate-- +Fixed fate, free will, foreknowledge absolute, +And found no end, in wandering mazes lost. +Of good and evil much they argued then, +Of happiness and final misery, +Passion and apathy, and glory and shame: +Vain wisdom all, and false philosophy!-- +Yet, with a pleasing sorcery, could charm +Pain for a while or anguish, and excite +Fallacious hope, or arm th' obdured breast +With stubborn patience as with triple steel. +Another part, in squadrons and gross bands, +On bold adventure to discover wide +That dismal world, if any clime perhaps +Might yield them easier habitation, bend +Four ways their flying march, along the banks +Of four infernal rivers, that disgorge +Into the burning lake their baleful streams-- +Abhorred Styx, the flood of deadly hate; +Sad Acheron of sorrow, black and deep; +Cocytus, named of lamentation loud +Heard on the rueful stream; fierce Phlegeton, +Whose waves of torrent fire inflame with rage. +Far off from these, a slow and silent stream, +Lethe, the river of oblivion, rolls +Her watery labyrinth, whereof who drinks +Forthwith his former state and being forgets-- +Forgets both joy and grief, pleasure and pain. +Beyond this flood a frozen continent +Lies dark and wild, beat with perpetual storms +Of whirlwind and dire hail, which on firm land +Thaws not, but gathers heap, and ruin seems +Of ancient pile; all else deep snow and ice, +A gulf profound as that Serbonian bog +Betwixt Damiata and Mount Casius old, +Where armies whole have sunk: the parching air +Burns frore, and cold performs th' effect of fire. +Thither, by harpy-footed Furies haled, +At certain revolutions all the damned +Are brought; and feel by turns the bitter change +Of fierce extremes, extremes by change more fierce, +From beds of raging fire to starve in ice +Their soft ethereal warmth, and there to pine +Immovable, infixed, and frozen round +Periods of time,--thence hurried back to fire. +They ferry over this Lethean sound +Both to and fro, their sorrow to augment, +And wish and struggle, as they pass, to reach +The tempting stream, with one small drop to lose +In sweet forgetfulness all pain and woe, +All in one moment, and so near the brink; +But Fate withstands, and, to oppose th' attempt, +Medusa with Gorgonian terror guards +The ford, and of itself the water flies +All taste of living wight, as once it fled +The lip of Tantalus. Thus roving on +In confused march forlorn, th' adventurous bands, +With shuddering horror pale, and eyes aghast, +Viewed first their lamentable lot, and found +No rest. Through many a dark and dreary vale +They passed, and many a region dolorous, +O'er many a frozen, many a fiery alp, +Rocks, caves, lakes, fens, bogs, dens, and shades of death-- +A universe of death, which God by curse +Created evil, for evil only good; +Where all life dies, death lives, and Nature breeds, +Perverse, all monstrous, all prodigious things, +Obominable, inutterable, and worse +Than fables yet have feigned or fear conceived, +Gorgons, and Hydras, and Chimeras dire. + Meanwhile the Adversary of God and Man, +Satan, with thoughts inflamed of highest design, +Puts on swift wings, and toward the gates of Hell +Explores his solitary flight: sometimes +He scours the right hand coast, sometimes the left; +Now shaves with level wing the deep, then soars +Up to the fiery concave towering high. +As when far off at sea a fleet descried +Hangs in the clouds, by equinoctial winds +Close sailing from Bengala, or the isles +Of Ternate and Tidore, whence merchants bring +Their spicy drugs; they on the trading flood, +Through the wide Ethiopian to the Cape, +Ply stemming nightly toward the pole: so seemed +Far off the flying Fiend. At last appear +Hell-bounds, high reaching to the horrid roof, +And thrice threefold the gates; three folds were brass, +Three iron, three of adamantine rock, +Impenetrable, impaled with circling fire, +Yet unconsumed. Before the gates there sat +On either side a formidable Shape. +The one seemed woman to the waist, and fair, +But ended foul in many a scaly fold, +Voluminous and vast--a serpent armed +With mortal sting. About her middle round +A cry of Hell-hounds never-ceasing barked +With wide Cerberean mouths full loud, and rung +A hideous peal; yet, when they list, would creep, +If aught disturbed their noise, into her womb, +And kennel there; yet there still barked and howled +Within unseen. Far less abhorred than these +Vexed Scylla, bathing in the sea that parts +Calabria from the hoarse Trinacrian shore; +Nor uglier follow the night-hag, when, called +In secret, riding through the air she comes, +Lured with the smell of infant blood, to dance +With Lapland witches, while the labouring moon +Eclipses at their charms. The other Shape-- +If shape it might be called that shape had none +Distinguishable in member, joint, or limb; +Or substance might be called that shadow seemed, +For each seemed either--black it stood as Night, +Fierce as ten Furies, terrible as Hell, +And shook a dreadful dart: what seemed his head +The likeness of a kingly crown had on. +Satan was now at hand, and from his seat +The monster moving onward came as fast +With horrid strides; Hell trembled as he strode. +Th' undaunted Fiend what this might be admired-- +Admired, not feared (God and his Son except, +Created thing naught valued he nor shunned), +And with disdainful look thus first began:-- + "Whence and what art thou, execrable Shape, +That dar'st, though grim and terrible, advance +Thy miscreated front athwart my way +To yonder gates? Through them I mean to pass, +That be assured, without leave asked of thee. +Retire; or taste thy folly, and learn by proof, +Hell-born, not to contend with Spirits of Heaven." + To whom the Goblin, full of wrath, replied:-- +"Art thou that traitor Angel? art thou he, +Who first broke peace in Heaven and faith, till then +Unbroken, and in proud rebellious arms +Drew after him the third part of Heaven's sons, +Conjured against the Highest--for which both thou +And they, outcast from God, are here condemned +To waste eternal days in woe and pain? +And reckon'st thou thyself with Spirits of Heaven +Hell-doomed, and breath'st defiance here and scorn, +Where I reign king, and, to enrage thee more, +Thy king and lord? Back to thy punishment, +False fugitive; and to thy speed add wings, +Lest with a whip of scorpions I pursue +Thy lingering, or with one stroke of this dart +Strange horror seize thee, and pangs unfelt before." + So spake the grisly Terror, and in shape, +So speaking and so threatening, grew tenfold, +More dreadful and deform. On th' other side, +Incensed with indignation, Satan stood +Unterrified, and like a comet burned, +That fires the length of Ophiuchus huge +In th' arctic sky, and from his horrid hair +Shakes pestilence and war. Each at the head +Levelled his deadly aim; their fatal hands +No second stroke intend; and such a frown +Each cast at th' other as when two black clouds, +With heaven's artillery fraught, came rattling on +Over the Caspian,--then stand front to front +Hovering a space, till winds the signal blow +To join their dark encounter in mid-air. +So frowned the mighty combatants that Hell +Grew darker at their frown; so matched they stood; +For never but once more was wither like +To meet so great a foe. And now great deeds +Had been achieved, whereof all Hell had rung, +Had not the snaky Sorceress, that sat +Fast by Hell-gate and kept the fatal key, +Risen, and with hideous outcry rushed between. + "O father, what intends thy hand," she cried, +"Against thy only son? What fury, O son, +Possesses thee to bend that mortal dart +Against thy father's head? And know'st for whom? +For him who sits above, and laughs the while +At thee, ordained his drudge to execute +Whate'er his wrath, which he calls justice, bids-- +His wrath, which one day will destroy ye both!" + She spake, and at her words the hellish Pest +Forbore: then these to her Satan returned:-- + "So strange thy outcry, and thy words so strange +Thou interposest, that my sudden hand, +Prevented, spares to tell thee yet by deeds +What it intends, till first I know of thee +What thing thou art, thus double-formed, and why, +In this infernal vale first met, thou call'st +Me father, and that phantasm call'st my son. +I know thee not, nor ever saw till now +Sight more detestable than him and thee." + T' whom thus the Portress of Hell-gate replied:-- +"Hast thou forgot me, then; and do I seem +Now in thine eye so foul?--once deemed so fair +In Heaven, when at th' assembly, and in sight +Of all the Seraphim with thee combined +In bold conspiracy against Heaven's King, +All on a sudden miserable pain +Surprised thee, dim thine eyes and dizzy swum +In darkness, while thy head flames thick and fast +Threw forth, till on the left side opening wide, +Likest to thee in shape and countenance bright, +Then shining heavenly fair, a goddess armed, +Out of thy head I sprung. Amazement seized +All th' host of Heaven; back they recoiled afraid +At first, and called me Sin, and for a sign +Portentous held me; but, familiar grown, +I pleased, and with attractive graces won +The most averse--thee chiefly, who, full oft +Thyself in me thy perfect image viewing, +Becam'st enamoured; and such joy thou took'st +With me in secret that my womb conceived +A growing burden. Meanwhile war arose, +And fields were fought in Heaven: wherein remained +(For what could else?) to our Almighty Foe +Clear victory; to our part loss and rout +Through all the Empyrean. Down they fell, +Driven headlong from the pitch of Heaven, down +Into this Deep; and in the general fall +I also: at which time this powerful key +Into my hands was given, with charge to keep +These gates for ever shut, which none can pass +Without my opening. Pensive here I sat +Alone; but long I sat not, till my womb, +Pregnant by thee, and now excessive grown, +Prodigious motion felt and rueful throes. +At last this odious offspring whom thou seest, +Thine own begotten, breaking violent way, +Tore through my entrails, that, with fear and pain +Distorted, all my nether shape thus grew +Transformed: but he my inbred enemy +Forth issued, brandishing his fatal dart, +Made to destroy. I fled, and cried out Death! +Hell trembled at the hideous name, and sighed +From all her caves, and back resounded Death! +I fled; but he pursued (though more, it seems, +Inflamed with lust than rage), and, swifter far, +Me overtook, his mother, all dismayed, +And, in embraces forcible and foul +Engendering with me, of that rape begot +These yelling monsters, that with ceaseless cry +Surround me, as thou saw'st--hourly conceived +And hourly born, with sorrow infinite +To me; for, when they list, into the womb +That bred them they return, and howl, and gnaw +My bowels, their repast; then, bursting forth +Afresh, with conscious terrors vex me round, +That rest or intermission none I find. +Before mine eyes in opposition sits +Grim Death, my son and foe, who set them on, +And me, his parent, would full soon devour +For want of other prey, but that he knows +His end with mine involved, and knows that I +Should prove a bitter morsel, and his bane, +Whenever that shall be: so Fate pronounced. +But thou, O father, I forewarn thee, shun +His deadly arrow; neither vainly hope +To be invulnerable in those bright arms, +Through tempered heavenly; for that mortal dint, +Save he who reigns above, none can resist." + She finished; and the subtle Fiend his lore +Soon learned, now milder, and thus answered smooth:-- + "Dear daughter--since thou claim'st me for thy sire, +And my fair son here show'st me, the dear pledge +Of dalliance had with thee in Heaven, and joys +Then sweet, now sad to mention, through dire change +Befallen us unforeseen, unthought-of--know, +I come no enemy, but to set free +From out this dark and dismal house of pain +Both him and thee, and all the heavenly host +Of Spirits that, in our just pretences armed, +Fell with us from on high. From them I go +This uncouth errand sole, and one for all +Myself expose, with lonely steps to tread +Th' unfounded Deep, and through the void immense +To search, with wandering quest, a place foretold +Should be--and, by concurring signs, ere now +Created vast and round--a place of bliss +In the purlieus of Heaven; and therein placed +A race of upstart creatures, to supply +Perhaps our vacant room, though more removed, +Lest Heaven, surcharged with potent multitude, +Might hap to move new broils. Be this, or aught +Than this more secret, now designed, I haste +To know; and, this once known, shall soon return, +And bring ye to the place where thou and Death +Shall dwell at ease, and up and down unseen +Wing silently the buxom air, embalmed +With odours. There ye shall be fed and filled +Immeasurably; all things shall be your prey." + He ceased; for both seemed highly pleased, and Death +Grinned horrible a ghastly smile, to hear +His famine should be filled, and blessed his maw +Destined to that good hour. No less rejoiced +His mother bad, and thus bespake her sire:-- + "The key of this infernal Pit, by due +And by command of Heaven's all-powerful King, +I keep, by him forbidden to unlock +These adamantine gates; against all force +Death ready stands to interpose his dart, +Fearless to be o'ermatched by living might. +But what owe I to his commands above, +Who hates me, and hath hither thrust me down +Into this gloom of Tartarus profound, +To sit in hateful office here confined, +Inhabitant of Heaven and heavenly born-- +Here in perpetual agony and pain, +With terrors and with clamours compassed round +Of mine own brood, that on my bowels feed? +Thou art my father, thou my author, thou +My being gav'st me; whom should I obey +But thee? whom follow? Thou wilt bring me soon +To that new world of light and bliss, among +The gods who live at ease, where I shall reign +At thy right hand voluptuous, as beseems +Thy daughter and thy darling, without end." + Thus saying, from her side the fatal key, +Sad instrument of all our woe, she took; +And, towards the gate rolling her bestial train, +Forthwith the huge portcullis high up-drew, +Which, but herself, not all the Stygian Powers +Could once have moved; then in the key-hole turns +Th' intricate wards, and every bolt and bar +Of massy iron or solid rock with ease +Unfastens. On a sudden open fly, +With impetuous recoil and jarring sound, +Th' infernal doors, and on their hinges grate +Harsh thunder, that the lowest bottom shook +Of Erebus. She opened; but to shut +Excelled her power: the gates wide open stood, +That with extended wings a bannered host, +Under spread ensigns marching, mibht pass through +With horse and chariots ranked in loose array; +So wide they stood, and like a furnace-mouth +Cast forth redounding smoke and ruddy flame. +Before their eyes in sudden view appear +The secrets of the hoary Deep--a dark +Illimitable ocean, without bound, +Without dimension; where length, breadth, and height, +And time, and place, are lost; where eldest Night +And Chaos, ancestors of Nature, hold +Eternal anarchy, amidst the noise +Of endless wars, and by confusion stand. +For Hot, Cold, Moist, and Dry, four champions fierce, +Strive here for mastery, and to battle bring +Their embryon atoms: they around the flag +Of each his faction, in their several clans, +Light-armed or heavy, sharp, smooth, swift, or slow, +Swarm populous, unnumbered as the sands +Of Barca or Cyrene's torrid soil, +Levied to side with warring winds, and poise +Their lighter wings. To whom these most adhere +He rules a moment: Chaos umpire sits, +And by decision more embroils the fray +By which he reigns: next him, high arbiter, +Chance governs all. Into this wild Abyss, +The womb of Nature, and perhaps her grave, +Of neither sea, nor shore, nor air, nor fire, +But all these in their pregnant causes mixed +Confusedly, and which thus must ever fight, +Unless th' Almighty Maker them ordain +His dark materials to create more worlds-- +Into this wild Abyss the wary Fiend +Stood on the brink of Hell and looked a while, +Pondering his voyage; for no narrow frith +He had to cross. Nor was his ear less pealed +With noises loud and ruinous (to compare +Great things with small) than when Bellona storms +With all her battering engines, bent to rase +Some capital city; or less than if this frame +Of Heaven were falling, and these elements +In mutiny had from her axle torn +The steadfast Earth. At last his sail-broad vans +He spread for flight, and, in the surging smoke +Uplifted, spurns the ground; thence many a league, +As in a cloudy chair, ascending rides +Audacious; but, that seat soon failing, meets +A vast vacuity. All unawares, +Fluttering his pennons vain, plumb-down he drops +Ten thousand fathom deep, and to this hour +Down had been falling, had not, by ill chance, +The strong rebuff of some tumultuous cloud, +Instinct with fire and nitre, hurried him +As many miles aloft. That fury stayed-- +Quenched in a boggy Syrtis, neither sea, +Nor good dry land--nigh foundered, on he fares, +Treading the crude consistence, half on foot, +Half flying; behoves him now both oar and sail. +As when a gryphon through the wilderness +With winged course, o'er hill or moory dale, +Pursues the Arimaspian, who by stealth +Had from his wakeful custody purloined +The guarded gold; so eagerly the Fiend +O'er bog or steep, through strait, rough, dense, or rare, +With head, hands, wings, or feet, pursues his way, +And swims, or sinks, or wades, or creeps, or flies. +At length a universal hubbub wild +Of stunning sounds, and voices all confused, +Borne through the hollow dark, assaults his ear +With loudest vehemence. Thither he plies +Undaunted, to meet there whatever Power +Or Spirit of the nethermost Abyss +Might in that noise reside, of whom to ask +Which way the nearest coast of darkness lies +Bordering on light; when straight behold the throne +Of Chaos, and his dark pavilion spread +Wide on the wasteful Deep! With him enthroned +Sat sable-vested Night, eldest of things, +The consort of his reign; and by them stood +Orcus and Ades, and the dreaded name +Of Demogorgon; Rumour next, and Chance, +And Tumult, and Confusion, all embroiled, +And Discord with a thousand various mouths. + T' whom Satan, turning boldly, thus:--"Ye Powers +And Spirtis of this nethermost Abyss, +Chaos and ancient Night, I come no spy +With purpose to explore or to disturb +The secrets of your realm; but, by constraint +Wandering this darksome desert, as my way +Lies through your spacious empire up to light, +Alone and without guide, half lost, I seek, +What readiest path leads where your gloomy bounds +Confine with Heaven; or, if some other place, +From your dominion won, th' Ethereal King +Possesses lately, thither to arrive +I travel this profound. Direct my course: +Directed, no mean recompense it brings +To your behoof, if I that region lost, +All usurpation thence expelled, reduce +To her original darkness and your sway +(Which is my present journey), and once more +Erect the standard there of ancient Night. +Yours be th' advantage all, mine the revenge!" + Thus Satan; and him thus the Anarch old, +With faltering speech and visage incomposed, +Answered: "I know thee, stranger, who thou art-- *** +That mighty leading Angel, who of late +Made head against Heaven's King, though overthrown. +I saw and heard; for such a numerous host +Fled not in silence through the frighted Deep, +With ruin upon ruin, rout on rout, +Confusion worse confounded; and Heaven-gates +Poured out by millions her victorious bands, +Pursuing. I upon my frontiers here +Keep residence; if all I can will serve +That little which is left so to defend, +Encroached on still through our intestine broils +Weakening the sceptre of old Night: first, Hell, +Your dungeon, stretching far and wide beneath; +Now lately Heaven and Earth, another world +Hung o'er my realm, linked in a golden chain +To that side Heaven from whence your legions fell! +If that way be your walk, you have not far; +So much the nearer danger. Go, and speed; +Havoc, and spoil, and ruin, are my gain." + He ceased; and Satan stayed not to reply, +But, glad that now his sea should find a shore, +With fresh alacrity and force renewed +Springs upward, like a pyramid of fire, +Into the wild expanse, and through the shock +Of fighting elements, on all sides round +Environed, wins his way; harder beset +And more endangered than when Argo passed +Through Bosporus betwixt the justling rocks, +Or when Ulysses on the larboard shunned +Charybdis, and by th' other whirlpool steered. +So he with difficulty and labour hard +Moved on, with difficulty and labour he; +But, he once passed, soon after, when Man fell, +Strange alteration! Sin and Death amain, +Following his track (such was the will of Heaven) +Paved after him a broad and beaten way +Over the dark Abyss, whose boiling gulf +Tamely endured a bridge of wondrous length, +From Hell continued, reaching th' utmost orb +Of this frail World; by which the Spirits perverse +With easy intercourse pass to and fro +To tempt or punish mortals, except whom +God and good Angels guard by special grace. + But now at last the sacred influence +Of light appears, and from the walls of Heaven +Shoots far into the bosom of dim Night +A glimmering dawn. Here Nature first begins +Her farthest verge, and Chaos to retire, +As from her outmost works, a broken foe, +With tumult less and with less hostile din; +That Satan with less toil, and now with ease, +Wafts on the calmer wave by dubious light, +And, like a weather-beaten vessel, holds +Gladly the port, though shrouds and tackle torn; +Or in the emptier waste, resembling air, +Weighs his spread wings, at leisure to behold +Far off th' empyreal Heaven, extended wide +In circuit, undetermined square or round, +With opal towers and battlements adorned +Of living sapphire, once his native seat; +And, fast by, hanging in a golden chain, +This pendent World, in bigness as a star +Of smallest magnitude close by the moon. +Thither, full fraught with mischievous revenge, +Accursed, and in a cursed hour, he hies. + + + +Book III + + +Hail, holy Light, offspring of Heaven firstborn, +Or of the Eternal coeternal beam +May I express thee unblam'd? since God is light, +And never but in unapproached light +Dwelt from eternity, dwelt then in thee +Bright effluence of bright essence increate. +Or hear"st thou rather pure ethereal stream, +Whose fountain who shall tell? before the sun, +Before the Heavens thou wert, and at the voice +Of God, as with a mantle, didst invest *** +The rising world of waters dark and deep, +Won from the void and formless infinite. +Thee I re-visit now with bolder wing, +Escap'd the Stygian pool, though long detain'd +In that obscure sojourn, while in my flight +Through utter and through middle darkness borne, +With other notes than to the Orphean lyre +I sung of Chaos and eternal Night; +Taught by the heavenly Muse to venture down +The dark descent, and up to re-ascend, +Though hard and rare: Thee I revisit safe, +And feel thy sovran vital lamp; but thou +Revisit'st not these eyes, that roll in vain +To find thy piercing ray, and find no dawn; +So thick a drop serene hath quench'd their orbs, +Or dim suffusion veil'd. Yet not the more +Cease I to wander, where the Muses haunt, +Clear spring, or shady grove, or sunny hill, +Smit with the love of sacred song; but chief +Thee, Sion, and the flowery brooks beneath, +That wash thy hallow'd feet, and warbling flow, +Nightly I visit: nor sometimes forget +So were I equall'd with them in renown, +Thy sovran command, that Man should find grace; +Blind Thamyris, and blind Maeonides, +And Tiresias, and Phineus, prophets old: +Then feed on thoughts, that voluntary move +Harmonious numbers; as the wakeful bird +Sings darkling, and in shadiest covert hid +Tunes her nocturnal note. Thus with the year +Seasons return; but not to me returns +Day, or the sweet approach of even or morn, +Or sight of vernal bloom, or summer's rose, +Or flocks, or herds, or human face divine; +But cloud instead, and ever-during dark +Surrounds me, from the cheerful ways of men +Cut off, and for the book of knowledge fair +Presented with a universal blank +Of nature's works to me expung'd and ras'd, +And wisdom at one entrance quite shut out. +So much the rather thou, celestial Light, +Shine inward, and the mind through all her powers +Irradiate; there plant eyes, all mist from thence +Purge and disperse, that I may see and tell +Of things invisible to mortal sight. +Now had the Almighty Father from above, +From the pure empyrean where he sits +High thron'd above all highth, bent down his eye +His own works and their works at once to view: +About him all the Sanctities of Heaven +Stood thick as stars, and from his sight receiv'd +Beatitude past utterance; on his right +The radiant image of his glory sat, +His only son; on earth he first beheld +Our two first parents, yet the only two +Of mankind in the happy garden plac'd +Reaping immortal fruits of joy and love, +Uninterrupted joy, unrivall'd love, +In blissful solitude; he then survey'd +Hell and the gulf between, and Satan there +Coasting the wall of Heaven on this side Night +In the dun air sublime, and ready now +To stoop with wearied wings, and willing feet, +On the bare outside of this world, that seem'd +Firm land imbosom'd, without firmament, +Uncertain which, in ocean or in air. +Him God beholding from his prospect high, +Wherein past, present, future, he beholds, +Thus to his only Son foreseeing spake. +Only begotten Son, seest thou what rage +Transports our Adversary? whom no bounds +Prescrib'd no bars of Hell, nor all the chains +Heap'd on him there, nor yet the main abyss +Wide interrupt, can hold; so bent he seems +On desperate revenge, that shall redound +Upon his own rebellious head. And now, +Through all restraint broke loose, he wings his way +Not far off Heaven, in the precincts of light, +Directly towards the new created world, +And man there plac'd, with purpose to assay +If him by force he can destroy, or, worse, +By some false guile pervert; and shall pervert; +For man will hearken to his glozing lies, +And easily transgress the sole command, +Sole pledge of his obedience: So will fall +He and his faithless progeny: Whose fault? +Whose but his own? ingrate, he had of me +All he could have; I made him just and right, +Sufficient to have stood, though free to fall. +Such I created all the ethereal Powers +And Spirits, both them who stood, and them who fail'd; +Freely they stood who stood, and fell who fell. +Not free, what proof could they have given sincere +Of true allegiance, constant faith or love, +Where only what they needs must do appear'd, +Not what they would? what praise could they receive? +What pleasure I from such obedience paid, +When will and reason (reason also is choice) +Useless and vain, of freedom both despoil'd, +Made passive both, had serv'd necessity, +Not me? they therefore, as to right belong$ 'd, +So were created, nor can justly accuse +Their Maker, or their making, or their fate, +As if predestination over-rul'd +Their will dispos'd by absolute decree +Or high foreknowledge they themselves decreed +Their own revolt, not I; if I foreknew, +Foreknowledge had no influence on their fault, +Which had no less proved certain unforeknown. +So without least impulse or shadow of fate, +Or aught by me immutably foreseen, +They trespass, authors to themselves in all +Both what they judge, and what they choose; for so +I form'd them free: and free they must remain, +Till they enthrall themselves; I else must change +Their nature, and revoke the high decree +Unchangeable, eternal, which ordain'd +$THeir freedom: they themselves ordain'd their fall. +The first sort by their own suggestion fell, +Self-tempted, self-deprav'd: Man falls, deceiv'd +By the other first: Man therefore shall find grace, +The other none: In mercy and justice both, +Through Heaven and Earth, so shall my glory excel; +But Mercy, first and last, shall brightest shine. +Thus while God spake, ambrosial fragrance fill'd +All Heaven, and in the blessed Spirits elect +Sense of new joy ineffable diffus'd. +Beyond compare the Son of God was seen +Most glorious; in him all his Father shone +Substantially express'd; and in his face +Divine compassion visibly appear'd, +Love without end, and without measure grace, +Which uttering, thus he to his Father spake. +O Father, gracious was that word which clos'd +Thy sovran command, that Man should find grace; +, that Man should find grace; +For which both Heaven and earth shall high extol +Thy praises, with the innumerable sound +Of hymns and sacred songs, wherewith thy throne +Encompass'd shall resound thee ever blest. +For should Man finally be lost, should Man, +Thy creature late so lov'd, thy youngest son, +Fall circumvented thus by fraud, though join'd +With his own folly? that be from thee far, +That far be from thee, Father, who art judge +Of all things made, and judgest only right. +Or shall the Adversary thus obtain +His end, and frustrate thine? shall he fulfill +His malice, and thy goodness bring to nought, +Or proud return, though to his heavier doom, +Yet with revenge accomplish'd, and to Hell +Draw after him the whole race of mankind, +By him corrupted? or wilt thou thyself +Abolish thy creation, and unmake +For him, what for thy glory thou hast made? +So should thy goodness and thy greatness both +Be question'd and blasphem'd without defence. +To whom the great Creator thus replied. +O son, in whom my soul hath chief delight, +Son of my bosom, Son who art alone. +My word, my wisdom, and effectual might, +All hast thou spoken as my thoughts are, all +As my eternal purpose hath decreed; +Man shall not quite be lost, but sav'd who will; +Yet not of will in him, but grace in me +Freely vouchsaf'd; once more I will renew +His lapsed powers, though forfeit; and enthrall'd +By sin to foul exorbitant desires; +Upheld by me, yet once more he shall stand +On even ground against his mortal foe; +By me upheld, that he may know how frail +His fallen condition is, and to me owe +All his deliverance, and to none but me. +Some I have chosen of peculiar grace, +Elect above the rest; so is my will: +The rest shall hear me call, and oft be warn'd +Their sinful state, and to appease betimes +The incensed Deity, while offer'd grace +Invites; for I will clear their senses dark, +What may suffice, and soften stony hearts +To pray, repent, and bring obedience due. +To prayer, repentance, and obedience due, +Though but endeavour'd with sincere intent, +Mine ear shall not be slow, mine eye not shut. +And I will place within them as a guide, +My umpire Conscience; whom if they will hear, +Light after light, well us'd, they shall attain, +And to the end, persisting, safe arrive. +This my long sufferance, and my day of grace, +They who neglect and scorn, shall never taste; +But hard be harden'd, blind be blinded more, +That they may stumble on, and deeper fall; +And none but such from mercy I exclude. +But yet all is not done; Man disobeying, +Disloyal, breaks his fealty, and sins +Against the high supremacy of Heaven, +Affecting God-head, and, so losing all, +To expiate his treason hath nought left, +But to destruction sacred and devote, +He, with his whole posterity, must die, +Die he or justice must; unless for him +Some other able, and as willing, pay +The rigid satisfaction, death for death. +Say, heavenly Powers, where shall we find such love? +Which of you will be mortal, to redeem +Man's mortal crime, and just the unjust to save? +Dwells in all Heaven charity so dear? +And silence was in Heaven: $ on Man's behalf +He ask'd, but all the heavenly quire stood mute, +Patron or intercessour none appear'd, +Much less that durst upon his own head draw +The deadly forfeiture, and ransom set. +And now without redemption all mankind +Must have been lost, adjudg'd to Death and Hell +By doom severe, had not the Son of God, +In whom the fulness dwells of love divine, +His dearest mediation thus renew'd. +Father, thy word is past, Man shall find grace; +And shall grace not find means, that finds her way, +The speediest of thy winged messengers, +To visit all thy creatures, and to all +Comes unprevented, unimplor'd, unsought? +Happy for Man, so coming; he her aid +Can never seek, once dead in sins, and lost; +Atonement for himself, or offering meet, +Indebted and undone, hath none to bring; +Behold me then: me for him, life for life +I offer: on me let thine anger fall; +Account me Man; I for his sake will leave + Thy bosom, and this glory next to thee + Freely put off, and for him lastly die + Well pleased; on me let Death wreak all his rage. + Under his gloomy power I shall not long + Lie vanquished. Thou hast given me to possess + Life in myself for ever; by thee I live; + Though now to Death I yield, and am his due, + All that of me can die, yet, that debt paid, + $ thou wilt not leave me in the loathsome grave + His prey, nor suffer my unspotted soul + For ever with corruption there to dwell; + But I shall rise victorious, and subdue + My vanquisher, spoiled of his vaunted spoil. + Death his death's wound shall then receive, and stoop + Inglorious, of his mortal sting disarmed; + I through the ample air in triumph high + Shall lead Hell captive maugre Hell, and show +The powers of darkness bound. Thou, at the sight + Pleased, out of Heaven shalt look down and smile, + While, by thee raised, I ruin all my foes; + Death last, and with his carcase glut the grave; + Then, with the multitude of my redeemed, + Shall enter Heaven, long absent, and return, + Father, to see thy face, wherein no cloud + Of anger shall remain, but peace assured + And reconcilement: wrath shall be no more + Thenceforth, but in thy presence joy entire. + His words here ended; but his meek aspect + Silent yet spake, and breathed immortal love + To mortal men, above which only shone + Filial obedience: as a sacrifice + Glad to be offered, he attends the will + Of his great Father. Admiration seized + All Heaven, what this might mean, and whither tend, + Wondering; but soon th' Almighty thus replied. + O thou in Heaven and Earth the only peace + Found out for mankind under wrath, O thou + My sole complacence! Well thou know'st how dear + To me are all my works; nor Man the least, + Though last created, that for him I spare + Thee from my bosom and right hand, to save, + By losing thee a while, the whole race lost. + + 00021053 + Thou, therefore, whom thou only canst redeem, + Their nature also to thy nature join; + And be thyself Man among men on Earth, + Made flesh, when time shall be, of virgin seed, + By wondrous birth; be thou in Adam's room +The head of all mankind, though Adam's son. +As in him perish all men, so in thee, +As from a second root, shall be restored +As many as are restored, without thee none. +His crime makes guilty all his sons; thy merit, +Imputed, shall absolve them who renounce +Their own both righteous and unrighteous deeds, +And live in thee transplanted, and from thee +Receive new life. So Man, as is most just, +Shall satisfy for Man, be judged and die, +And dying rise, and rising with him raise +His brethren, ransomed with his own dear life. +So heavenly love shall outdo hellish hate, +Giving to death, and dying to redeem, +So dearly to redeem what hellish hate +So easily destroyed, and still destroys +In those who, when they may, accept not grace. +Nor shalt thou, by descending to assume +Man's nature, lessen or degrade thine own. +Because thou hast, though throned in highest bliss +Equal to God, and equally enjoying +God-like fruition, quitted all, to save +A world from utter loss, and hast been found +By merit more than birthright Son of God, +Found worthiest to be so by being good, +Far more than great or high; because in thee +Love hath abounded more than glory abounds; +Therefore thy humiliation shall exalt +With thee thy manhood also to this throne: +Here shalt thou sit incarnate, here shalt reign +Both God and Man, Son both of God and Man, +Anointed universal King; all power +I give thee; reign for ever, and assume +Thy merits; under thee, as head supreme, +Thrones, Princedoms, Powers, Dominions, I reduce: +All knees to thee shall bow, of them that bide +In Heaven, or Earth, or under Earth in Hell. +When thou, attended gloriously from Heaven, +Shalt in the sky appear, and from thee send +The summoning Arch-Angels to proclaim +Thy dread tribunal; forthwith from all winds, +The living, and forthwith the cited dead +Of all past ages, to the general doom +Shall hasten; such a peal shall rouse their sleep. +Then, all thy saints assembled, thou shalt judge +Bad Men and Angels; they, arraigned, shall sink +Beneath thy sentence; Hell, her numbers full, +Thenceforth shall be for ever shut. Mean while +The world shall burn, and from her ashes spring +New Heaven and Earth, wherein the just shall dwell, +And, after all their tribulations long, +See golden days, fruitful of golden deeds, +With joy and peace triumphing, and fair truth. +Then thou thy regal scepter shalt lay by, +For regal scepter then no more shall need, +God shall be all in all. But, all ye Gods, +Adore him, who to compass all this dies; +Adore the Son, and honour him as me. +No sooner had the Almighty ceased, but all +The multitude of Angels, with a shout +Loud as from numbers without number, sweet +As from blest voices, uttering joy, Heaven rung +With jubilee, and loud Hosannas filled +The eternal regions: Lowly reverent +Towards either throne they bow, and to the ground +With solemn adoration down they cast +Their crowns inwove with amarant and gold; +Immortal amarant, a flower which once +In Paradise, fast by the tree of life, +Began to bloom; but soon for man's offence +To Heaven removed, where first it grew, there grows, +And flowers aloft shading the fount of life, +And where the river of bliss through midst of Heaven +Rolls o'er Elysian flowers her amber stream; +With these that never fade the Spirits elect +Bind their resplendent locks inwreathed with beams; +Now in loose garlands thick thrown off, the bright +Pavement, that like a sea of jasper shone, +Impurpled with celestial roses smiled. +Then, crowned again, their golden harps they took, +Harps ever tuned, that glittering by their side +Like quivers hung, and with preamble sweet +Of charming symphony they introduce +Their sacred song, and waken raptures high; +No voice exempt, no voice but well could join +Melodious part, such concord is in Heaven. +Thee, Father, first they sung Omnipotent, +Immutable, Immortal, Infinite, +Eternal King; the Author of all being, +Fonntain of light, thyself invisible +Amidst the glorious brightness where thou sit'st +Throned inaccessible, but when thou shadest +The full blaze of thy beams, and, through a cloud +Drawn round about thee like a radiant shrine, +Dark with excessive bright thy skirts appear, +Yet dazzle Heaven, that brightest Seraphim +Approach not, but with both wings veil their eyes. +Thee next they sang of all creation first, +Begotten Son, Divine Similitude, +In whose conspicuous countenance, without cloud +Made visible, the Almighty Father shines, +Whom else no creature can behold; on thee +Impressed the effulgence of his glory abides, +Transfused on thee his ample Spirit rests. +He Heaven of Heavens and all the Powers therein +By thee created; and by thee threw down +The aspiring Dominations: Thou that day +Thy Father's dreadful thunder didst not spare, +Nor stop thy flaming chariot-wheels, that shook +Heaven's everlasting frame, while o'er the necks +Thou drovest of warring Angels disarrayed. +Back from pursuit thy Powers with loud acclaim +Thee only extolled, Son of thy Father's might, +To execute fierce vengeance on his foes, +Not so on Man: Him through their malice fallen, +Father of mercy and grace, thou didst not doom +So strictly, but much more to pity incline: +No sooner did thy dear and only Son +Perceive thee purposed not to doom frail Man +So strictly, but much more to pity inclined, +He to appease thy wrath, and end the strife +Of mercy and justice in thy face discerned, +Regardless of the bliss wherein he sat +Second to thee, offered himself to die +For Man's offence. O unexampled love, +Love no where to be found less than Divine! +Hail, Son of God, Saviour of Men! Thy name +Shall be the copious matter of my song +Henceforth, and never shall my heart thy praise +Forget, nor from thy Father's praise disjoin. +Thus they in Heaven, above the starry sphere, +Their happy hours in joy and hymning spent. +Mean while upon the firm opacous globe +Of this round world, whose first convex divides +The luminous inferiour orbs, enclosed +From Chaos, and the inroad of Darkness old, +Satan alighted walks: A globe far off +It seemed, now seems a boundless continent +Dark, waste, and wild, under the frown of Night +Starless exposed, and ever-threatening storms +Of Chaos blustering round, inclement sky; +Save on that side which from the wall of Heaven, +Though distant far, some small reflection gains +Of glimmering air less vexed with tempest loud: +Here walked the Fiend at large in spacious field. +As when a vultur on Imaus bred, +Whose snowy ridge the roving Tartar bounds, +Dislodging from a region scarce of prey +To gorge the flesh of lambs or yeanling kids, +On hills where flocks are fed, flies toward the springs +Of Ganges or Hydaspes, Indian streams; +But in his way lights on the barren plains +Of Sericana, where Chineses drive +With sails and wind their cany waggons light: +So, on this windy sea of land, the Fiend +Walked up and down alone, bent on his prey; +Alone, for other creature in this place, +Living or lifeless, to be found was none; +None yet, but store hereafter from the earth +Up hither like aereal vapours flew +Of all things transitory and vain, when sin +With vanity had filled the works of men: +Both all things vain, and all who in vain things +Built their fond hopes of glory or lasting fame, +Or happiness in this or the other life; +All who have their reward on earth, the fruits +Of painful superstition and blind zeal, +Nought seeking but the praise of men, here find +Fit retribution, empty as their deeds; +All the unaccomplished works of Nature's hand, +Abortive, monstrous, or unkindly mixed, +Dissolved on earth, fleet hither, and in vain, +Till final dissolution, wander here; +Not in the neighbouring moon as some have dreamed; +Those argent fields more likely habitants, +Translated Saints, or middle Spirits hold +Betwixt the angelical and human kind. +Hither of ill-joined sons and daughters born +First from the ancient world those giants came +With many a vain exploit, though then renowned: +The builders next of Babel on the plain +Of Sennaar, and still with vain design, +New Babels, had they wherewithal, would build: +Others came single; he, who, to be deemed +A God, leaped fondly into Aetna flames, +Empedocles; and he, who, to enjoy +Plato's Elysium, leaped into the sea, +Cleombrotus; and many more too long, +Embryos, and idiots, eremites, and friars +White, black, and gray, with all their trumpery. +Here pilgrims roam, that strayed so far to seek +In Golgotha him dead, who lives in Heaven; +And they, who to be sure of Paradise, +Dying, put on the weeds of Dominick, +Or in Franciscan think to pass disguised; +They pass the planets seven, and pass the fixed, +And that crystalling sphere whose balance weighs +The trepidation talked, and that first moved; +And now Saint Peter at Heaven's wicket seems +To wait them with his keys, and now at foot +Of Heaven's ascent they lift their feet, when lo +A violent cross wind from either coast +Blows them transverse, ten thousand leagues awry +Into the devious air: Then might ye see +Cowls, hoods, and habits, with their wearers, tost +And fluttered into rags; then reliques, beads, +Indulgences, dispenses, pardons, bulls, +The sport of winds: All these, upwhirled aloft, +Fly o'er the backside of the world far off +Into a Limbo large and broad, since called +The Paradise of Fools, to few unknown +Long after; now unpeopled, and untrod. +All this dark globe the Fiend found as he passed, +And long he wandered, till at last a gleam +Of dawning light turned thither-ward in haste +His travelled steps: far distant he descries +Ascending by degrees magnificent +Up to the wall of Heaven a structure high; +At top whereof, but far more rich, appeared +The work as of a kingly palace-gate, +With frontispiece of diamond and gold +Embellished; thick with sparkling orient gems +The portal shone, inimitable on earth +By model, or by shading pencil, drawn. +These stairs were such as whereon Jacob saw +Angels ascending and descending, bands +Of guardians bright, when he from Esau fled +To Padan-Aram, in the field of Luz +Dreaming by night under the open sky +And waking cried, This is the gate of Heaven. +Each stair mysteriously was meant, nor stood +There always, but drawn up to Heaven sometimes +Viewless; and underneath a bright sea flowed +Of jasper, or of liquid pearl, whereon +Who after came from earth, failing arrived +Wafted by Angels, or flew o'er the lake +Rapt in a chariot drawn by fiery steeds. +The stairs were then let down, whether to dare +The Fiend by easy ascent, or aggravate +His sad exclusion from the doors of bliss: +Direct against which opened from beneath, +Just o'er the blissful seat of Paradise, +A passage down to the Earth, a passage wide, +Wider by far than that of after-times +Over mount Sion, and, though that were large, +Over the Promised Land to God so dear; +By which, to visit oft those happy tribes, +On high behests his angels to and fro +Passed frequent, and his eye with choice regard +From Paneas, the fount of Jordan's flood, +To Beersaba, where the Holy Land +Borders on Egypt and the Arabian shore; +So wide the opening seemed, where bounds were set +To darkness, such as bound the ocean wave. +Satan from hence, now on the lower stair, +That scaled by steps of gold to Heaven-gate, +Looks down with wonder at the sudden view +Of all this world at once. As when a scout, +Through dark?;nd desart ways with?oeril gone +All?might,?;t?kast by break of cheerful dawn +Obtains the brow of some high-climbing hill, +Which to his eye discovers unaware +The goodly prospect of some foreign land +First seen, or some renowned metropolis +With glistering spires and pinnacles adorned, +Which now the rising sun gilds with his beams: +Such wonder seised, though after Heaven seen, +The Spirit malign, but much more envy seised, +At sight of all this world beheld so fair. +Round he surveys (and well might, where he stood +So high above the circling canopy +Of night's extended shade,) from eastern point +Of Libra to the fleecy star that bears +Andromeda far off Atlantick seas +Beyond the horizon; then from pole to pole +He views in breadth, and without longer pause +Down right into the world's first region throws +His flight precipitant, and winds with ease +Through the pure marble air his oblique way +Amongst innumerable stars, that shone +Stars distant, but nigh hand seemed other worlds; +Or other worlds they seemed, or happy isles, +Like those Hesperian gardens famed of old, +Fortunate fields, and groves, and flowery vales, +Thrice happy isles; but who dwelt happy there +He staid not to inquire: Above them all +The golden sun, in splendour likest Heaven, +Allured his eye; thither his course he bends +Through the calm firmament, (but up or down, +By center, or eccentrick, hard to tell, +Or longitude,) where the great luminary +Aloof the vulgar constellations thick, +That from his lordly eye keep distance due, +Dispenses light from far; they, as they move +Their starry dance in numbers that compute +Days, months, and years, towards his all-cheering lamp +Turn swift their various motions, or are turned +By his magnetick beam, that gently warms +The universe, and to each inward part +With gentle penetration, though unseen, +Shoots invisible virtue even to the deep; +So wonderously was set his station bright. +There lands the Fiend, a spot like which perhaps +Astronomer in the sun's lucent orb +Through his glazed optick tube yet never saw. +The place he found beyond expression bright, +Compared with aught on earth, metal or stone; +Not all parts like, but all alike informed +With radiant light, as glowing iron with fire; +If metal, part seemed gold, part silver clear; +If stone, carbuncle most or chrysolite, +Ruby or topaz, to the twelve that shone +In Aaron's breast-plate, and a stone besides +Imagined rather oft than elsewhere seen, +That stone, or like to that which here below +Philosophers in vain so long have sought, +In vain, though by their powerful art they bind +Volatile Hermes, and call up unbound +In various shapes old Proteus from the sea, +Drained through a limbeck to his native form. +What wonder then if fields and regions here +Breathe forth Elixir pure, and rivers run +Potable gold, when with one virtuous touch +The arch-chemick sun, so far from us remote, +Produces, with terrestrial humour mixed, +Here in the dark so many precious things +Of colour glorious, and effect so rare? +Here matter new to gaze the Devil met +Undazzled; far and wide his eye commands; +For sight no obstacle found here, nor shade, +But all sun-shine, as when his beams at noon +Culminate from the equator, as they now +Shot upward still direct, whence no way round +Shadow from body opaque can fall; and the air, +No where so clear, sharpened his visual ray +To objects distant far, whereby he soon +Saw within ken a glorious Angel stand, +The same whom John saw also in the sun: +His back was turned, but not his brightness hid; +Of beaming sunny rays a golden tiar +Circled his head, nor less his locks behind +Illustrious on his shoulders fledge with wings +Lay waving round; on some great charge employed +He seemed, or fixed in cogitation deep. +Glad was the Spirit impure, as now in hope +To find who might direct his wandering flight +To Paradise, the happy seat of Man, +His journey's end and our beginning woe. +But first he casts to change his proper shape, +Which else might work him danger or delay: +And now a stripling Cherub he appears, +Not of the prime, yet such as in his face +Youth smiled celestial, and to every limb +Suitable grace diffused, so well he feigned: +Under a coronet his flowing hair +In curls on either cheek played; wings he wore +Of many a coloured plume, sprinkled with gold; +His habit fit for speed succinct, and held +Before his decent steps a silver wand. +He drew not nigh unheard; the Angel bright, +Ere he drew nigh, his radiant visage turned, +Admonished by his ear, and straight was known +The Arch-Angel Uriel, one of the seven +Who in God's presence, nearest to his throne, +Stand ready at command, and are his eyes +That run through all the Heavens, or down to the Earth +Bear his swift errands over moist and dry, +O'er sea and land: him Satan thus accosts. +Uriel, for thou of those seven Spirits that stand +In sight of God's high throne, gloriously bright, +The first art wont his great authentick will +Interpreter through highest Heaven to bring, +Where all his sons thy embassy attend; +And here art likeliest by supreme decree +Like honour to obtain, and as his eye +To visit oft this new creation round; +Unspeakable desire to see, and know +All these his wonderous works, but chiefly Man, +His chief delight and favour, him for whom +All these his works so wonderous he ordained, +Hath brought me from the quires of Cherubim +Alone thus wandering. Brightest Seraph, tell +In which of all these shining orbs hath Man +His fixed seat, or fixed seat hath none, +But all these shining orbs his choice to dwell; +That I may find him, and with secret gaze +Or open admiration him behold, +On whom the great Creator hath bestowed +Worlds, and on whom hath all these graces poured; +That both in him and all things, as is meet, +The universal Maker we may praise; +Who justly hath driven out his rebel foes +To deepest Hell, and, to repair that loss, +Created this new happy race of Men +To serve him better: Wise are all his ways. +So spake the false dissembler unperceived; +For neither Man nor Angel can discern +Hypocrisy, the only evil that walks +Invisible, except to God alone, +By his permissive will, through Heaven and Earth: +And oft, though wisdom wake, suspicion sleeps +At wisdom's gate, and to simplicity +Resigns her charge, while goodness thinks no ill +Where no ill seems: Which now for once beguiled +Uriel, though regent of the sun, and held +The sharpest-sighted Spirit of all in Heaven; +Who to the fraudulent impostor foul, +In his uprightness, answer thus returned. +Fair Angel, thy desire, which tends to know +The works of God, thereby to glorify +The great Work-master, leads to no excess +That reaches blame, but rather merits praise +The more it seems excess, that led thee hither +From thy empyreal mansion thus alone, +To witness with thine eyes what some perhaps, +Contented with report, hear only in Heaven: +For wonderful indeed are all his works, +Pleasant to know, and worthiest to be all +Had in remembrance always with delight; +But what created mind can comprehend +Their number, or the wisdom infinite +That brought them forth, but hid their causes deep? +I saw when at his word the formless mass, +This world's material mould, came to a heap: +Confusion heard his voice, and wild uproar +Stood ruled, stood vast infinitude confined; +Till at his second bidding Darkness fled, +Light shone, and order from disorder sprung: +Swift to their several quarters hasted then +The cumbrous elements, earth, flood, air, fire; +And this ethereal quintessence of Heaven +Flew upward, spirited with various forms, +That rolled orbicular, and turned to stars +Numberless, as thou seest, and how they move; +Each had his place appointed, each his course; +The rest in circuit walls this universe. +Look downward on that globe, whose hither side +With light from hence, though but reflected, shines; +That place is Earth, the seat of Man; that light +His day, which else, as the other hemisphere, +Night would invade; but there the neighbouring moon +So call that opposite fair star) her aid +Timely interposes, and her monthly round +Still ending, still renewing, through mid Heaven, +With borrowed light her countenance triform +Hence fills and empties to enlighten the Earth, +And in her pale dominion checks the night. +That spot, to which I point, is Paradise, +Adam's abode; those lofty shades, his bower. +Thy way thou canst not miss, me mine requires. +Thus said, he turned; and Satan, bowing low, +As to superiour Spirits is wont in Heaven, +Where honour due and reverence none neglects, +Took leave, and toward the coast of earth beneath, +Down from the ecliptick, sped with hoped success, +Throws his steep flight in many an aery wheel; +Nor staid, till on Niphates' top he lights. + + + +Book IV + + +O, for that warning voice, which he, who saw +The Apocalypse, heard cry in Heaven aloud, +Then when the Dragon, put to second rout, +Came furious down to be revenged on men, +Woe to the inhabitants on earth! that now, +While time was, our first parents had been warned +The coming of their secret foe, and 'scaped, +Haply so 'scaped his mortal snare: For now +Satan, now first inflamed with rage, came down, +The tempter ere the accuser of mankind, +To wreak on innocent frail Man his loss +Of that first battle, and his flight to Hell: +Yet, not rejoicing in his speed, though bold +Far off and fearless, nor with cause to boast, +Begins his dire attempt; which nigh the birth +Now rolling boils in his tumultuous breast, +And like a devilish engine back recoils +Upon himself; horrour and doubt distract +His troubled thoughts, and from the bottom stir +The Hell within him; for within him Hell +He brings, and round about him, nor from Hell +One step, no more than from himself, can fly +By change of place: Now conscience wakes despair, +That slumbered; wakes the bitter memory +Of what he was, what is, and what must be +Worse; of worse deeds worse sufferings must ensue. +Sometimes towards Eden, which now in his view +Lay pleasant, his grieved look he fixes sad; +Sometimes towards Heaven, and the full-blazing sun, +Which now sat high in his meridian tower: +Then, much revolving, thus in sighs began. +O thou, that, with surpassing glory crowned, +Lookest from thy sole dominion like the God +Of this new world; at whose sight all the stars +Hide their diminished heads; to thee I call, +But with no friendly voice, and add thy name, +Of Sun! to tell thee how I hate thy beams, +That bring to my remembrance from what state +I fell, how glorious once above thy sphere; +Till pride and worse ambition threw me down +Warring in Heaven against Heaven's matchless King: +Ah, wherefore! he deserved no such return +From me, whom he created what I was +In that bright eminence, and with his good +Upbraided none; nor was his service hard. +What could be less than to afford him praise, +The easiest recompence, and pay him thanks, +How due! yet all his good proved ill in me, +And wrought but malice; lifted up so high +I sdeined subjection, and thought one step higher +Would set me highest, and in a moment quit +The debt immense of endless gratitude, +So burdensome still paying, still to owe, +Forgetful what from him I still received, +And understood not that a grateful mind +By owing owes not, but still pays, at once +Indebted and discharged; what burden then +O, had his powerful destiny ordained +Me some inferiour Angel, I had stood +Then happy; no unbounded hope had raised +Ambition! Yet why not some other Power +As great might have aspired, and me, though mean, +Drawn to his part; but other Powers as great +Fell not, but stand unshaken, from within +Or from without, to all temptations armed. +Hadst thou the same free will and power to stand? +Thou hadst: whom hast thou then or what to accuse, +But Heaven's free love dealt equally to all? +Be then his love accursed, since love or hate, +To me alike, it deals eternal woe. +Nay, cursed be thou; since against his thy will +Chose freely what it now so justly rues. +Me miserable! which way shall I fly +Infinite wrath, and infinite despair? +Which way I fly is Hell; myself am Hell; +And, in the lowest deep, a lower deep +Still threatening to devour me opens wide, +To which the Hell I suffer seems a Heaven. +O, then, at last relent: Is there no place +Left for repentance, none for pardon left? +None left but by submission; and that word +Disdain forbids me, and my dread of shame +Among the Spirits beneath, whom I seduced +With other promises and other vaunts +Than to submit, boasting I could subdue +The Omnipotent. Ay me! they little know +How dearly I abide that boast so vain, +Under what torments inwardly I groan, +While they adore me on the throne of Hell. +With diadem and scepter high advanced, +The lower still I fall, only supreme +In misery: Such joy ambition finds. +But say I could repent, and could obtain, +By act of grace, my former state; how soon +Would highth recall high thoughts, how soon unsay +What feigned submission swore? Ease would recant +Vows made in pain, as violent and void. +For never can true reconcilement grow, +Where wounds of deadly hate have pierced so deep: +Which would but lead me to a worse relapse +And heavier fall: so should I purchase dear +Short intermission bought with double smart. +This knows my Punisher; therefore as far +From granting he, as I from begging, peace; +All hope excluded thus, behold, in stead +Mankind created, and for him this world. +So farewell, hope; and with hope farewell, fear; +Farewell, remorse! all good to me is lost; +Evil, be thou my good; by thee at least +Divided empire with Heaven's King I hold, +By thee, and more than half perhaps will reign; +As Man ere long, and this new world, shall know. +Thus while he spake, each passion dimmed his face +Thrice changed with pale, ire, envy, and despair; +Which marred his borrowed visage, and betrayed +Him counterfeit, if any eye beheld. +For heavenly minds from such distempers foul +Are ever clear. Whereof he soon aware, +Each perturbation smoothed with outward calm, +Artificer of fraud; and was the first +That practised falsehood under saintly show, +Deep malice to conceal, couched with revenge: +Yet not enough had practised to deceive +Uriel once warned; whose eye pursued him down + The way he went, and on the Assyrian mount + Saw him disfigured, more than could befall + Spirit of happy sort; his gestures fierce + He marked and mad demeanour, then alone, + As he supposed, all unobserved, unseen. + So on he fares, and to the border comes + Of Eden, where delicious Paradise, + Now nearer, crowns with her enclosure green, + As with a rural mound, the champaign head + Of a steep wilderness, whose hairy sides +Access denied; and overhead upgrew + Insuperable height of loftiest shade, + Cedar, and pine, and fir, and branching palm, + A sylvan scene, and, as the ranks ascend, + Shade above shade, a woody theatre + Of stateliest view. Yet higher than their tops + The verdurous wall of Paradise upsprung; + + 00081429 +Which to our general sire gave prospect large +Into his nether empire neighbouring round. +And higher than that wall a circling row +Of goodliest trees, loaden with fairest fruit, +Blossoms and fruits at once of golden hue, +Appeared, with gay enamelled colours mixed: +On which the sun more glad impressed his beams +Than in fair evening cloud, or humid bow, +When God hath showered the earth; so lovely seemed +That landskip: And of pure now purer air +Meets his approach, and to the heart inspires +Vernal delight and joy, able to drive +All sadness but despair: Now gentle gales, +Fanning their odoriferous wings, dispense +Native perfumes, and whisper whence they stole +Those balmy spoils. As when to them who fail +Beyond the Cape of Hope, and now are past +Mozambick, off at sea north-east winds blow +Sabean odours from the spicy shore +Of Araby the blest; with such delay +Well pleased they slack their course, and many a league +Cheered with the grateful smell old Ocean smiles: +So entertained those odorous sweets the Fiend, +Who came their bane; though with them better pleased +Than Asmodeus with the fishy fume +That drove him, though enamoured, from the spouse +Of Tobit's son, and with a vengeance sent +From Media post to Egypt, there fast bound. +Now to the ascent of that steep savage hill +Satan had journeyed on, pensive and slow; +But further way found none, so thick entwined, +As one continued brake, the undergrowth +Of shrubs and tangling bushes had perplexed +All path of man or beast that passed that way. +One gate there only was, and that looked east +On the other side: which when the arch-felon saw, +Due entrance he disdained; and, in contempt, +At one flight bound high over-leaped all bound +Of hill or highest wall, and sheer within +Lights on his feet. As when a prowling wolf, +Whom hunger drives to seek new haunt for prey, +Watching where shepherds pen their flocks at eve +In hurdled cotes amid the field secure, +Leaps o'er the fence with ease into the fold: +Or as a thief, bent to unhoard the cash +Of some rich burgher, whose substantial doors, +Cross-barred and bolted fast, fear no assault, +In at the window climbs, or o'er the tiles: +So clomb this first grand thief into God's fold; +So since into his church lewd hirelings climb. +Thence up he flew, and on the tree of life, +The middle tree and highest there that grew, +Sat like a cormorant; yet not true life +Thereby regained, but sat devising death +To them who lived; nor on the virtue thought +Of that life-giving plant, but only used +For prospect, what well used had been the pledge +Of immortality. So little knows +Any, but God alone, to value right +The good before him, but perverts best things +To worst abuse, or to their meanest use. +Beneath him with new wonder now he views, +To all delight of human sense exposed, +In narrow room, Nature's whole wealth, yea more, +A Heaven on Earth: For blissful Paradise +Of God the garden was, by him in the east +Of Eden planted; Eden stretched her line +From Auran eastward to the royal towers +Of great Seleucia, built by Grecian kings, +Of where the sons of Eden long before +Dwelt in Telassar: In this pleasant soil +His far more pleasant garden God ordained; +Out of the fertile ground he caused to grow +All trees of noblest kind for sight, smell, taste; +And all amid them stood the tree of life, +High eminent, blooming ambrosial fruit +Of vegetable gold; and next to life, +Our death, the tree of knowledge, grew fast by, +Knowledge of good bought dear by knowing ill. +Southward through Eden went a river large, +Nor changed his course, but through the shaggy hill +Passed underneath ingulfed; for God had thrown +That mountain as his garden-mould high raised +Upon the rapid current, which, through veins +Of porous earth with kindly thirst up-drawn, +Rose a fresh fountain, and with many a rill +Watered the garden; thence united fell +Down the steep glade, and met the nether flood, +Which from his darksome passage now appears, +And now, divided into four main streams, +Runs diverse, wandering many a famous realm +And country, whereof here needs no account; +But rather to tell how, if Art could tell, +How from that sapphire fount the crisped brooks, +Rolling on orient pearl and sands of gold, +With mazy errour under pendant shades +Ran nectar, visiting each plant, and fed +Flowers worthy of Paradise, which not nice Art +In beds and curious knots, but Nature boon +Poured forth profuse on hill, and dale, and plain, +Both where the morning sun first warmly smote +The open field, and where the unpierced shade +Imbrowned the noontide bowers: Thus was this place +A happy rural seat of various view; +Groves whose rich trees wept odorous gums and balm, +Others whose fruit, burnished with golden rind, +Hung amiable, Hesperian fables true, +If true, here only, and of delicious taste: +Betwixt them lawns, or level downs, and flocks +Grazing the tender herb, were interposed, +Or palmy hillock; or the flowery lap +Of some irriguous valley spread her store, +Flowers of all hue, and without thorn the rose: +Another side, umbrageous grots and caves +Of cool recess, o'er which the mantling vine +Lays forth her purple grape, and gently creeps +Luxuriant; mean while murmuring waters fall +Down the slope hills, dispersed, or in a lake, +That to the fringed bank with myrtle crowned +Her crystal mirrour holds, unite their streams. +The birds their quire apply; airs, vernal airs, +Breathing the smell of field and grove, attune +The trembling leaves, while universal Pan, +Knit with the Graces and the Hours in dance, +Led on the eternal Spring. Not that fair field +Of Enna, where Proserpine gathering flowers, +Herself a fairer flower by gloomy Dis +Was gathered, which cost Ceres all that pain +To seek her through the world; nor that sweet grove +Of Daphne by Orontes, and the inspired +Castalian spring, might with this Paradise +Of Eden strive; nor that Nyseian isle +Girt with the river Triton, where old Cham, +Whom Gentiles Ammon call and Libyan Jove, +Hid Amalthea, and her florid son +Young Bacchus, from his stepdame Rhea's eye; +Nor where Abassin kings their issue guard, +Mount Amara, though this by some supposed +True Paradise under the Ethiop line +By Nilus' head, enclosed with shining rock, +A whole day's journey high, but wide remote +From this Assyrian garden, where the Fiend +Saw, undelighted, all delight, all kind +Of living creatures, new to sight, and strange +Two of far nobler shape, erect and tall, +Godlike erect, with native honour clad +In naked majesty seemed lords of all: +And worthy seemed; for in their looks divine +The image of their glorious Maker shone, +Truth, wisdom, sanctitude severe and pure, +(Severe, but in true filial freedom placed,) +Whence true authority in men; though both +Not equal, as their sex not equal seemed; +For contemplation he and valour formed; +For softness she and sweet attractive grace; +He for God only, she for God in him: +His fair large front and eye sublime declared +Absolute rule; and hyacinthine locks +Round from his parted forelock manly hung +Clustering, but not beneath his shoulders broad: +She, as a veil, down to the slender waist +Her unadorned golden tresses wore +Dishevelled, but in wanton ringlets waved +As the vine curls her tendrils, which implied +Subjection, but required with gentle sway, +And by her yielded, by him best received, +Yielded with coy submission, modest pride, +And sweet, reluctant, amorous delay. +Nor those mysterious parts were then concealed; +Then was not guilty shame, dishonest shame +Of nature's works, honour dishonourable, +Sin-bred, how have ye troubled all mankind +With shows instead, mere shows of seeming pure, +And banished from man's life his happiest life, +Simplicity and spotless innocence! +So passed they naked on, nor shunned the sight +Of God or Angel; for they thought no ill: +So hand in hand they passed, the loveliest pair, +That ever since in love's embraces met; +Adam the goodliest man of men since born +His sons, the fairest of her daughters Eve. +Under a tuft of shade that on a green +Stood whispering soft, by a fresh fountain side +They sat them down; and, after no more toil +Of their sweet gardening labour than sufficed +To recommend cool Zephyr, and made ease +More easy, wholesome thirst and appetite +More grateful, to their supper-fruits they fell, +Nectarine fruits which the compliant boughs +Yielded them, side-long as they sat recline +On the soft downy bank damasked with flowers: +The savoury pulp they chew, and in the rind, +Still as they thirsted, scoop the brimming stream; +Nor gentle purpose, nor endearing smiles +Wanted, nor youthful dalliance, as beseems +Fair couple, linked in happy nuptial league, +Alone as they. About them frisking played +All beasts of the earth, since wild, and of all chase +In wood or wilderness, forest or den; +Sporting the lion ramped, and in his paw +Dandled the kid; bears, tigers, ounces, pards, +Gambolled before them; the unwieldy elephant, +To make them mirth, used all his might, and wreathed +His?kithetmroboscis; close the serpent sly, +Insinuating, wove with Gordian twine +His braided train, and of his fatal guile +Gave proof unheeded; others on the grass +Couched, and now filled with pasture gazing sat, +Or bedward ruminating; for the sun, +Declined, was hasting now with prone career +To the ocean isles, and in the ascending scale +Of Heaven the stars that usher evening rose: +When Satan still in gaze, as first he stood, +Scarce thus at length failed speech recovered sad. +O Hell! what do mine eyes with grief behold! +Into our room of bliss thus high advanced +Creatures of other mould, earth-born perhaps, +Not Spirits, yet to heavenly Spirits bright +Little inferiour; whom my thoughts pursue +With wonder, and could love, so lively shines +In them divine resemblance, and such grace +The hand that formed them on their shape hath poured. +Ah! gentle pair, ye little think how nigh +Your change approaches, when all these delights +Will vanish, and deliver ye to woe; +More woe, the more your taste is now of joy; +Happy, but for so happy ill secured +Long to continue, and this high seat your Heaven +Ill fenced for Heaven to keep out such a foe +As now is entered; yet no purposed foe +To you, whom I could pity thus forlorn, +Though I unpitied: League with you I seek, +And mutual amity, so strait, so close, +That I with you must dwell, or you with me +Henceforth; my dwelling haply may not please, +Like this fair Paradise, your sense; yet such +Accept your Maker's work; he gave it me, +Which I as freely give: Hell shall unfold, +To entertain you two, her widest gates, +And send forth all her kings; there will be room, +Not like these narrow limits, to receive +Your numerous offspring; if no better place, +Thank him who puts me loth to this revenge +On you who wrong me not for him who wronged. +And should I at your harmless innocence +Melt, as I do, yet publick reason just, +Honour and empire with revenge enlarged, +By conquering this new world, compels me now +To do what else, though damned, I should abhor. +So spake the Fiend, and with necessity, +The tyrant's plea, excused his devilish deeds. +Then from his lofty stand on that high tree +Down he alights among the sportful herd +Of those four-footed kinds, himself now one, +Now other, as their shape served best his end +Nearer to view his prey, and, unespied, +To mark what of their state he more might learn, +By word or action marked. About them round +A lion now he stalks with fiery glare; +Then as a tiger, who by chance hath spied +In some purlieu two gentle fawns at play, +Straight couches close, then, rising, changes oft +His couchant watch, as one who chose his ground, +Whence rushing, he might surest seize them both, +Griped in each paw: when, Adam first of men +To first of women Eve thus moving speech, +Turned him, all ear to hear new utterance flow. +Sole partner, and sole part, of all these joys, +Dearer thyself than all; needs must the Power +That made us, and for us this ample world, +Be infinitely good, and of his good +As liberal and free as infinite; +That raised us from the dust, and placed us here +In all this happiness, who at his hand +Have nothing merited, nor can perform +Aught whereof he hath need; he who requires +From us no other service than to keep +This one, this easy charge, of all the trees +In Paradise that bear delicious fruit +So various, not to taste that only tree +Of knowledge, planted by the tree of life; +So near grows death to life, whate'er death is, +Some dreadful thing no doubt; for well thou knowest +God hath pronounced it death to taste that tree, +The only sign of our obedience left, +Among so many signs of power and rule +Conferred upon us, and dominion given +Over all other creatures that possess +Earth, air, and sea. Then let us not think hard +One easy prohibition, who enjoy +Free leave so large to all things else, and choice +Unlimited of manifold delights: +But let us ever praise him, and extol +His bounty, following our delightful task, +To prune these growing plants, and tend these flowers, +Which were it toilsome, yet with thee were sweet. +To whom thus Eve replied. O thou for whom +And from whom I was formed, flesh of thy flesh, +And without whom am to no end, my guide +And head! what thou hast said is just and right. +For we to him indeed all praises owe, +And daily thanks; I chiefly, who enjoy +So far the happier lot, enjoying thee +Pre-eminent by so much odds, while thou +Like consort to thyself canst no where find. +That day I oft remember, when from sleep +I first awaked, and found myself reposed +Under a shade on flowers, much wondering where +And what I was, whence thither brought, and how. +Not distant far from thence a murmuring sound +Of waters issued from a cave, and spread +Into a liquid plain, then stood unmoved +Pure as the expanse of Heaven; I thither went +With unexperienced thought, and laid me down +On the green bank, to look into the clear +Smooth lake, that to me seemed another sky. +As I bent down to look, just opposite +A shape within the watery gleam appeared, +Bending to look on me: I started back, +It started back; but pleased I soon returned, +Pleased it returned as soon with answering looks +Of sympathy and love: There I had fixed +Mine eyes till now, and pined with vain desire, +Had not a voice thus warned me; 'What thou seest, +'What there thou seest, fair Creature, is thyself; +'With thee it came and goes: but follow me, +'And I will bring thee where no shadow stays +'Thy coming, and thy soft embraces, he +'Whose image thou art; him thou shalt enjoy +'Inseparably thine, to him shalt bear +'Multitudes like thyself, and thence be called +'Mother of human race.' What could I do, +But follow straight, invisibly thus led? +Till I espied thee, fair indeed and tall, +Under a platane; yet methought less fair, +Less winning soft, less amiably mild, +Than that smooth watery image: Back I turned; +Thou following cryedst aloud, 'Return, fair Eve; +'Whom flyest thou? whom thou flyest, of him thou art, +'His flesh, his bone; to give thee being I lent +'Out of my side to thee, nearest my heart, +'Substantial life, to have thee by my side +'Henceforth an individual solace dear; +'Part of my soul I seek thee, and thee claim +'My other half:' With that thy gentle hand +Seised mine: I yielded;and from that time see +How beauty is excelled by manly grace, +And wisdom, which alone is truly fair. +So spake our general mother, and with eyes +Of conjugal attraction unreproved, +And meek surrender, half-embracing leaned +On our first father; half her swelling breast +Naked met his, under the flowing gold +Of her loose tresses hid: he in delight +Both of her beauty, and submissive charms, +Smiled with superiour love, as Jupiter +On Juno smiles, when he impregns the clouds +That shed Mayflowers; and pressed her matron lip +With kisses pure: Aside the Devil turned +For envy; yet with jealous leer malign +Eyed them askance, and to himself thus plained. +Sight hateful, sight tormenting! thus these two, +Imparadised in one another's arms, +The happier Eden, shall enjoy their fill +Of bliss on bliss; while I to Hell am thrust, +Where neither joy nor love, but fierce desire, +Among our other torments not the least, +Still unfulfilled with pain of longing pines. +Yet let me not forget what I have gained +From their own mouths: All is not theirs, it seems; +One fatal tree there stands, of knowledge called, +Forbidden them to taste: Knowledge forbidden +Suspicious, reasonless. Why should their Lord +Envy them that? Can it be sin to know? +Can it be death? And do they only stand +By ignorance? Is that their happy state, +The proof of their obedience and their faith? +O fair foundation laid whereon to build +Their ruin! hence I will excite their minds +With more desire to know, and to reject +Envious commands, invented with design +To keep them low, whom knowledge might exalt +Equal with Gods: aspiring to be such, +They taste and die: What likelier can ensue +But first with narrow search I must walk round +This garden, and no corner leave unspied; +A chance but chance may lead where I may meet +Some wandering Spirit of Heaven by fountain side, +Or in thick shade retired, from him to draw +What further would be learned. Live while ye may, +Yet happy pair; enjoy, till I return, +Short pleasures, for long woes are to succeed! +So saying, his proud step he scornful turned, +But with sly circumspection, and began +Through wood, through waste, o'er hill, o'er dale, his roam +Mean while in utmost longitude, where Heaven +With earth and ocean meets, the setting sun +Slowly descended, and with right aspect +Against the eastern gate of Paradise +Levelled his evening rays: It was a rock +Of alabaster, piled up to the clouds, +Conspicuous far, winding with one ascent +Accessible from earth, one entrance high; +The rest was craggy cliff, that overhung +Still as it rose, impossible to climb. +Betwixt these rocky pillars Gabriel sat, +Chief of the angelick guards, awaiting night; +About him exercised heroick games +The unarmed youth of Heaven, but nigh at hand +Celestial armoury, shields, helms, and spears, +Hung high with diamond flaming, and with gold. +Thither came Uriel, gliding through the even +On a sun-beam, swift as a shooting star +In autumn thwarts the night, when vapours fired +Impress the air, and shows the mariner +From what point of his compass to beware +Impetuous winds: He thus began in haste. +Gabriel, to thee thy course by lot hath given +Charge and strict watch, that to this happy place +No evil thing approach or enter in. +This day at highth of noon came to my sphere +A Spirit, zealous, as he seemed, to know +More of the Almighty's works, and chiefly Man, +God's latest image: I described his way +Bent all on speed, and marked his aery gait; +But in the mount that lies from Eden north, +Where he first lighted, soon discerned his looks +Alien from Heaven, with passions foul obscured: +Mine eye pursued him still, but under shade +Lost sight of him: One of the banished crew, +I fear, hath ventured from the deep, to raise +New troubles; him thy care must be to find. +To whom the winged warriour thus returned. +Uriel, no wonder if thy perfect sight, +Amid the sun's bright circle where thou sitst, +See far and wide: In at this gate none pass +The vigilance here placed, but such as come +Well known from Heaven; and since meridian hour +No creature thence: If Spirit of other sort, +So minded, have o'er-leaped these earthly bounds +On purpose, hard thou knowest it to exclude +Spiritual substance with corporeal bar. +But if within the circuit of these walks, +In whatsoever shape he lurk, of whom +Thou tellest, by morrow dawning I shall know. +So promised he; and Uriel to his charge +Returned on that bright beam, whose point now raised +Bore him slope downward to the sun now fallen +Beneath the Azores; whether the prime orb, +Incredible how swift, had thither rolled +Diurnal, or this less volubil earth, +By shorter flight to the east, had left him there +Arraying with reflected purple and gold +The clouds that on his western throne attend. +Now came still Evening on, and Twilight gray +Had in her sober livery all things clad; +Silence accompanied; for beast and bird, +They to their grassy couch, these to their nests +Were slunk, all but the wakeful nightingale; +She all night long her amorous descant sung; +Silence was pleased: Now glowed the firmament +With living sapphires: Hesperus, that led +The starry host, rode brightest, till the moon, +Rising in clouded majesty, at length +Apparent queen unveiled her peerless light, +And o'er the dark her silver mantle threw. +When Adam thus to Eve. Fair Consort, the hour +Of night, and all things now retired to rest, +Mind us of like repose; since God hath set +Labour and rest, as day and night, to men +Successive; and the timely dew of sleep, +Now falling with soft slumbrous weight, inclines +Our eye-lids: Other creatures all day long +Rove idle, unemployed, and less need rest; +Man hath his daily work of body or mind +Appointed, which declares his dignity, +And the regard of Heaven on all his ways; +While other animals unactive range, +And of their doings God takes no account. +To-morrow, ere fresh morning streak the east +With first approach of light, we must be risen, +And at our pleasant labour, to reform +Yon flowery arbours, yonder alleys green, +Our walk at noon, with branches overgrown, +That mock our scant manuring, and require +More hands than ours to lop their wanton growth: +Those blossoms also, and those dropping gums, +That lie bestrown, unsightly and unsmooth, +Ask riddance, if we mean to tread with ease; +Mean while, as Nature wills, night bids us rest. +To whom thus Eve, with perfect beauty adorned +My Author and Disposer, what thou bidst +Unargued I obey: So God ordains; +God is thy law, thou mine: To know no more +Is woman's happiest knowledge, and her praise. +With thee conversing I forget all time; +All seasons, and their change, all please alike. +Sweet is the breath of Morn, her rising sweet, +With charm of earliest birds: pleasant the sun, +When first on this delightful land he spreads +His orient beams, on herb, tree, fruit, and flower, +Glistering with dew; fragrant the fertile earth +After soft showers; and sweet the coming on +Of grateful Evening mild; then silent Night, +With this her solemn bird, and this fair moon, +And these the gems of Heaven, her starry train: +But neither breath of Morn, when she ascends +With charm of earliest birds; nor rising sun +On this delightful land; nor herb, fruit, flower, +Glistering with dew; nor fragrance after showers; +Nor grateful Evening mild; nor silent Night, +With this her solemn bird, nor walk by moon, +Or glittering star-light, without thee is sweet. +But wherefore all night long shine these? for whom +This glorious sight, when sleep hath shut all eyes? +To whom our general ancestor replied. +Daughter of God and Man, accomplished Eve, +These have their course to finish round the earth, +By morrow evening, and from land to land +In order, though to nations yet unborn, +Ministring light prepared, they set and rise; +Lest total Darkness should by night regain +Her old possession, and extinguish life +In Nature and all things; which these soft fires +Not only enlighten, but with kindly heat +Of various influence foment and warm, +Temper or nourish, or in part shed down +Their stellar virtue on all kinds that grow +On earth, made hereby apter to receive +Perfection from the sun's more potent ray. +These then, though unbeheld in deep of night, +Shine not in vain; nor think, though men were none, +That Heaven would want spectators, God want praise: +Millions of spiritual creatures walk the earth +Unseen, both when we wake, and when we sleep: +All these with ceaseless praise his works behold +Both day and night: How often from the steep +Of echoing hill or thicket have we heard +Celestial voices to the midnight air, +Sole, or responsive each to others note, +Singing their great Creator? oft in bands +While they keep watch, or nightly rounding walk, +With heavenly touch of instrumental sounds +In full harmonick number joined, their songs +Divide the night, and lift our thoughts to Heaven. +Thus talking, hand in hand alone they passed +On to their blissful bower: it was a place +Chosen by the sovran Planter, when he framed +All things to Man's delightful use; the roof +Of thickest covert was inwoven shade +Laurel and myrtle, and what higher grew +Of firm and fragrant leaf; on either side +Acanthus, and each odorous bushy shrub, +Fenced up the verdant wall; each beauteous flower, +Iris all hues, roses, and jessamin, +Reared high their flourished heads between, and wrought +Mosaick; underfoot the violet, +Crocus, and hyacinth, with rich inlay +Broidered the ground, more coloured than with stone +Of costliest emblem: Other creature here, +Bird, beast, insect, or worm, durst enter none, +Such was their awe of Man. In shadier bower +More sacred and sequestered, though but feigned, +Pan or Sylvanus never slept, nor Nymph +Nor Faunus haunted. Here, in close recess, +With flowers, garlands, and sweet-smelling herbs, +Espoused Eve decked first her nuptial bed; +And heavenly quires the hymenaean sung, +What day the genial Angel to our sire +Brought her in naked beauty more adorned, +More lovely, than Pandora, whom the Gods +Endowed with all their gifts, and O! too like +In sad event, when to the unwiser son +Of Japhet brought by Hermes, she ensnared +Mankind with her fair looks, to be avenged +On him who had stole Jove's authentick fire. +Thus, at their shady lodge arrived, both stood, +Both turned, and under open sky adored +The God that made both sky, air, earth, and heaven, +Which they beheld, the moon's resplendent globe, +And starry pole: Thou also madest the night, +Maker Omnipotent, and thou the day, +Which we, in our appointed work employed, +Have finished, happy in our mutual help +And mutual love, the crown of all our bliss +Ordained by thee; and this delicious place +For us too large, where thy abundance wants +Partakers, and uncropt falls to the ground. +But thou hast promised from us two a race +To fill the earth, who shall with us extol +Thy goodness infinite, both when we wake, +And when we seek, as now, thy gift of sleep. +This said unanimous, and other rites +Observing none, but adoration pure +Which God likes best, into their inmost bower +Handed they went; and, eased the putting off +These troublesome disguises which we wear, +Straight side by side were laid; nor turned, I ween, +Adam from his fair spouse, nor Eve the rites +Mysterious of connubial love refused: +Whatever hypocrites austerely talk +Of purity, and place, and innocence, +Defaming as impure what God declares +Pure, and commands to some, leaves free to all. +Our Maker bids encrease; who bids abstain +But our Destroyer, foe to God and Man? +Hail, wedded Love, mysterious law, true source +Of human offspring, sole propriety +In Paradise of all things common else! +By thee adulterous Lust was driven from men +Among the bestial herds to range; by thee +Founded in reason, loyal, just, and pure, +Relations dear, and all the charities +Of father, son, and brother, first were known. +Far be it, that I should write thee sin or blame, +Or think thee unbefitting holiest place, +Perpetual fountain of domestick sweets, +Whose bed is undefiled and chaste pronounced, +Present, or past, as saints and patriarchs used. +Here Love his golden shafts employs, here lights +His constant lamp, and waves his purple wings, +Reigns here and revels; not in the bought smile +Of harlots, loveless, joyless, unendeared, +Casual fruition; nor in court-amours, +Mixed dance, or wanton mask, or midnight ball, +Or serenate, which the starved lover sings +To his proud fair, best quitted with disdain. +These, lulled by nightingales, embracing slept, +And on their naked limbs the flowery roof +Showered roses, which the morn repaired. Sleep on, +Blest pair; and O!yet happiest, if ye seek +No happier state, and know to know no more. +Now had night measured with her shadowy cone +Half way up hill this vast sublunar vault, +And from their ivory port the Cherubim, +Forth issuing at the accustomed hour, stood armed +To their night watches in warlike parade; +When Gabriel to his next in power thus spake. +Uzziel, half these draw off, and coast the south +With strictest watch; these other wheel the north; +Our circuit meets full west. As flame they part, +Half wheeling to the shield, half to the spear. +From these, two strong and subtle Spirits he called +That near him stood, and gave them thus in charge. +Ithuriel and Zephon, with winged speed +Search through this garden, leave unsearched no nook; +But chiefly where those two fair creatures lodge, +Now laid perhaps asleep, secure of harm. +This evening from the sun's decline arrived, +Who tells of some infernal Spirit seen +Hitherward bent (who could have thought?) escaped +The bars of Hell, on errand bad no doubt: +Such, where ye find, seise fast, and hither bring. +So saying, on he led his radiant files, +Dazzling the moon; these to the bower direct +In search of whom they sought: Him there they found +Squat like a toad, close at the ear of Eve, +Assaying by his devilish art to reach +The organs of her fancy, and with them forge +Illusions, as he list, phantasms and dreams; +Or if, inspiring venom, he might taint +The animal spirits, that from pure blood arise +Like gentle breaths from rivers pure, thence raise +At least distempered, discontented thoughts, +Vain hopes, vain aims, inordinate desires, +Blown up with high conceits ingendering pride. +Him thus intent Ithuriel with his spear +Touched lightly; for no falshood can endure +Touch of celestial temper, but returns +Of force to its own likeness: Up he starts +Discovered and surprised. As when a spark +Lights on a heap of nitrous powder, laid +Fit for the tun some magazine to store +Against a rumoured war, the smutty grain, +With sudden blaze diffused, inflames the air; +So started up in his own shape the Fiend. +Back stept those two fair Angels, half amazed +So sudden to behold the grisly king; +Yet thus, unmoved with fear, accost him soon. +Which of those rebel Spirits adjudged to Hell +Comest thou, escaped thy prison? and, transformed, +Why sat'st thou like an enemy in wait, +Here watching at the head of these that sleep? +Know ye not then said Satan, filled with scorn, +Know ye not me? ye knew me once no mate +For you, there sitting where ye durst not soar: +Not to know me argues yourselves unknown, +The lowest of your throng; or, if ye know, +Why ask ye, and superfluous begin +Your message, like to end as much in vain? +To whom thus Zephon, answering scorn with scorn. +Think not, revolted Spirit, thy shape the same, +Or undiminished brightness to be known, +As when thou stoodest in Heaven upright and pure; +That glory then, when thou no more wast good, +Departed from thee; and thou resemblest now +Thy sin and place of doom obscure and foul. +But come, for thou, be sure, shalt give account +To him who sent us, whose charge is to keep +This place inviolable, and these from harm. +So spake the Cherub; and his grave rebuke, +Severe in youthful beauty, added grace +Invincible: Abashed the Devil stood, +And felt how awful goodness is, and saw +Virtue in her shape how lovely; saw, and pined +His loss; but chiefly to find here observed +His lustre visibly impaired; yet seemed +Undaunted. If I must contend, said he, +Best with the best, the sender, not the sent, +Or all at once; more glory will be won, +Or less be lost. Thy fear, said Zephon bold, +Will save us trial what the least can do +Single against thee wicked, and thence weak. +The Fiend replied not, overcome with rage; +But, like a proud steed reined, went haughty on, +Champing his iron curb: To strive or fly +He held it vain; awe from above had quelled +His heart, not else dismayed. Now drew they nigh +The western point, where those half-rounding guards +Just met, and closing stood in squadron joined, +A waiting next command. To whom their Chief, +Gabriel, from the front thus called aloud. +O friends! I hear the tread of nimble feet +Hasting this way, and now by glimpse discern +Ithuriel and Zephon through the shade; +And with them comes a third of regal port, +But faded splendour wan; who by his gait +And fierce demeanour seems the Prince of Hell, +Not likely to part hence without contest; +Stand firm, for in his look defiance lours. +He scarce had ended, when those two approached, +And brief related whom they brought, where found, +How busied, in what form and posture couched. +To whom with stern regard thus Gabriel spake. +Why hast thou, Satan, broke the bounds prescribed +To thy transgressions, and disturbed the charge +Of others, who approve not to transgress +By thy example, but have power and right +To question thy bold entrance on this place; +Employed, it seems, to violate sleep, and those +Whose dwelling God hath planted here in bliss! +To whom thus Satan with contemptuous brow. +Gabriel? thou hadst in Heaven the esteem of wise, +And such I held thee; but this question asked +Puts me in doubt. Lives there who loves his pain! +Who would not, finding way, break loose from Hell, +Though thither doomed! Thou wouldst thyself, no doubt +And boldly venture to whatever place +Farthest from pain, where thou mightst hope to change +Torment with ease, and soonest recompense +Dole with delight, which in this place I sought; +To thee no reason, who knowest only good, +But evil hast not tried: and wilt object +His will who bounds us! Let him surer bar +His iron gates, if he intends our stay +In that dark durance: Thus much what was asked. +The rest is true, they found me where they say; +But that implies not violence or harm. +Thus he in scorn. The warlike Angel moved, +Disdainfully half smiling, thus replied. +O loss of one in Heaven to judge of wise +Since Satan fell, whom folly overthrew, +And now returns him from his prison 'scaped, +Gravely in doubt whether to hold them wise +Or not, who ask what boldness brought him hither +Unlicensed from his bounds in Hell prescribed; +So wise he judges it to fly from pain +However, and to 'scape his punishment! +So judge thou still, presumptuous! till the wrath, +Which thou incurrest by flying, meet thy flight +Sevenfold, and scourge that wisdom back to Hell, +Which taught thee yet no better, that no pain +Can equal anger infinite provoked. +But wherefore thou alone? wherefore with thee +Came not all hell broke loose? or thou than they +Less hardy to endure? Courageous Chief! +The first in flight from pain! hadst thou alleged +To thy deserted host this cause of flight, +Thou surely hadst not come sole fugitive. +To which the Fiend thus answered, frowning stern. +Not that I less endure, or shrink from pain, +Insulting Angel! well thou knowest I stood +Thy fiercest, when in battle to thy aid +The blasting vollied thunder made all speed, +And seconded thy else not dreaded spear. +But still thy words at random, as before, +Argue thy inexperience what behoves +From hard assays and ill successes past +A faithful leader, not to hazard all +Through ways of danger by himself untried: +I, therefore, I alone first undertook +To wing the desolate abyss, and spy +This new created world, whereof in Hell +Fame is not silent, here in hope to find +Better abode, and my afflicted Powers +To settle here on earth, or in mid air; +Though for possession put to try once more +What thou and thy gay legions dare against; +Whose easier business were to serve their Lord +High up in Heaven, with songs to hymn his throne, +And practised distances to cringe, not fight, +To whom the warriour Angel soon replied. +To say and straight unsay, pretending first +Wise to fly pain, professing next the spy, +Argues no leader but a liear traced, +Satan, and couldst thou faithful add? O name, +O sacred name of faithfulness profaned! +Faithful to whom? to thy rebellious crew? +Army of Fiends, fit body to fit head. +Was this your discipline and faith engaged, +Your military obedience, to dissolve +Allegiance to the acknowledged Power supreme? +And thou, sly hypocrite, who now wouldst seem +Patron of liberty, who more than thou +Once fawned, and cringed, and servily adored +Heaven's awful Monarch? wherefore, but in hope +To dispossess him, and thyself to reign? +But mark what I arreed thee now, Avant; +Fly neither whence thou fledst! If from this hour +Within these hallowed limits thou appear, +Back to the infernal pit I drag thee chained, +And seal thee so, as henceforth not to scorn +The facile gates of Hell too slightly barred. +So threatened he; but Satan to no threats +Gave heed, but waxing more in rage replied. +Then when I am thy captive talk of chains, +Proud limitary Cherub! but ere then +Far heavier load thyself expect to feel +From my prevailing arm, though Heaven's King +Ride on thy wings, and thou with thy compeers, +Us'd to the yoke, drawest his triumphant wheels +In progress through the road of Heaven star-paved. +While thus he spake, the angelick squadron bright +Turned fiery red, sharpening in mooned horns +Their phalanx, and began to hem him round +With ported spears, as thick as when a field +Of Ceres ripe for harvest waving bends +Her bearded grove of ears, which way the wind +Sways them; the careful plowman doubting stands, +Left on the threshing floor his hopeless sheaves +Prove chaff. On the other side, Satan, alarmed, +Collecting all his might, dilated stood, +Like Teneriff or Atlas, unremoved: +His stature reached the sky, and on his crest +Sat Horrour plumed; nor wanted in his grasp +What seemed both spear and shield: Now dreadful deeds +Might have ensued, nor only Paradise +In this commotion, but the starry cope +Of Heaven perhaps, or all the elements +At least had gone to wrack, disturbed and torn +With violence of this conflict, had not soon +The Eternal, to prevent such horrid fray, +Hung forth in Heaven his golden scales, yet seen +Betwixt Astrea and the Scorpion sign, +Wherein all things created first he weighed, +The pendulous round earth with balanced air +In counterpoise, now ponders all events, +Battles and realms: In these he put two weights, +The sequel each of parting and of fight: +The latter quick up flew, and kicked the beam, +Which Gabriel spying, thus bespake the Fiend. +Satan, I know thy strength, and thou knowest mine; +Neither our own, but given: What folly then +To boast what arms can do? since thine no more +Than Heaven permits, nor mine, though doubled now +To trample thee as mire: For proof look up, +And read thy lot in yon celestial sign; +Where thou art weighed, and shown how light, how weak, +If thou resist. The Fiend looked up, and knew +His mounted scale aloft: Nor more;but fled +Murmuring, and with him fled the shades of night. + + + +Book V + + +Now Morn, her rosy steps in the eastern clime +Advancing, sowed the earth with orient pearl, +When Adam waked, so customed; for his sleep +Was aery-light, from pure digestion bred, +And temperate vapours bland, which the only sound +Of leaves and fuming rills, Aurora's fan, +Lightly dispersed, and the shrill matin song +Of birds on every bough; so much the more +His wonder was to find unwakened Eve +With tresses discomposed, and glowing cheek, +As through unquiet rest: He, on his side +Leaning half raised, with looks of cordial love +Hung over her enamoured, and beheld +Beauty, which, whether waking or asleep, +Shot forth peculiar graces; then with voice +Mild, as when Zephyrus on Flora breathes, +Her hand soft touching, whispered thus. Awake, +My fairest, my espoused, my latest found, +Heaven's last best gift, my ever new delight! +Awake: The morning shines, and the fresh field +Calls us; we lose the prime, to mark how spring +Our tender plants, how blows the citron grove, +What drops the myrrh, and what the balmy reed, +How nature paints her colours, how the bee +Sits on the bloom extracting liquid sweet. +Such whispering waked her, but with startled eye +On Adam, whom embracing, thus she spake. +O sole in whom my thoughts find all repose, +My glory, my perfection! glad I see +Thy face, and morn returned; for I this night +(Such night till this I never passed) have dreamed, +If dreamed, not, as I oft am wont, of thee, +Works of day past, or morrow's next design, +But of offence and trouble, which my mind +Knew never till this irksome night: Methought, +Close at mine ear one called me forth to walk +With gentle voice; I thought it thine: It said, +'Why sleepest thou, Eve? now is the pleasant time, +'The cool, the silent, save where silence yields +'To the night-warbling bird, that now awake +'Tunes sweetest his love-laboured song; now reigns +'Full-orbed the moon, and with more pleasing light +'Shadowy sets off the face of things; in vain, +'If none regard; Heaven wakes with all his eyes, +'Whom to behold but thee, Nature's desire? +'In whose sight all things joy, with ravishment +'Attracted by thy beauty still to gaze.' +I rose as at thy call, but found thee not; +To find thee I directed then my walk; +And on, methought, alone I passed through ways +That brought me on a sudden to the tree +Of interdicted knowledge: fair it seemed, +Much fairer to my fancy than by day: +And, as I wondering looked, beside it stood +One shaped and winged like one of those from Heaven +By us oft seen; his dewy locks distilled +Ambrosia; on that tree he also gazed; +And 'O fair plant,' said he, 'with fruit surcharged, +'Deigns none to ease thy load, and taste thy sweet, +'Nor God, nor Man? Is knowledge so despised? +'Or envy, or what reserve forbids to taste? +'Forbid who will, none shall from me withhold +'Longer thy offered good; why else set here? +This said, he paused not, but with venturous arm +He plucked, he tasted; me damp horrour chilled +At such bold words vouched with a deed so bold: +But he thus, overjoyed; 'O fruit divine, +'Sweet of thyself, but much more sweet thus cropt, +'Forbidden here, it seems, as only fit +'For Gods, yet able to make Gods of Men: +'And why not Gods of Men; since good, the more +'Communicated, more abundant grows, +'The author not impaired, but honoured more? +'Here, happy creature, fair angelick Eve! +'Partake thou also; happy though thou art, +'Happier thou mayest be, worthier canst not be: +'Taste this, and be henceforth among the Gods +'Thyself a Goddess, not to earth confined, +'But sometimes in the air, as we, sometimes +'Ascend to Heaven, by merit thine, and see +'What life the Gods live there, and such live thou!' +So saying, he drew nigh, and to me held, +Even to my mouth of that same fruit held part +Which he had plucked; the pleasant savoury smell +So quickened appetite, that I, methought, +Could not but taste. Forthwith up to the clouds +With him I flew, and underneath beheld +The earth outstretched immense, a prospect wide +And various: Wondering at my flight and change +To this high exaltation; suddenly +My guide was gone, and I, methought, sunk down, +And fell asleep; but O, how glad I waked +To find this but a dream! Thus Eve her night +Related, and thus Adam answered sad. +Best image of myself, and dearer half, +The trouble of thy thoughts this night in sleep +Affects me equally; nor can I like +This uncouth dream, of evil sprung, I fear; +Yet evil whence? in thee can harbour none, +Created pure. But know that in the soul +Are many lesser faculties, that serve +Reason as chief; among these Fancy next +Her office holds; of all external things +Which the five watchful senses represent, +She forms imaginations, aery shapes, +Which Reason, joining or disjoining, frames +All what we affirm or what deny, and call +Our knowledge or opinion; then retires +Into her private cell, when nature rests. +Oft in her absence mimick Fancy wakes +To imitate her; but, misjoining shapes, +Wild work produces oft, and most in dreams; +Ill matching words and deeds long past or late. +Some such resemblances, methinks, I find +Of our last evening's talk, in this thy dream, +But with addition strange; yet be not sad. +Evil into the mind of God or Man +May come and go, so unreproved, and leave +No spot or blame behind: Which gives me hope +That what in sleep thou didst abhor to dream, +Waking thou never will consent to do. +Be not disheartened then, nor cloud those looks, +That wont to be more cheerful and serene, +Than when fair morning first smiles on the world; +And let us to our fresh employments rise +Among the groves, the fountains, and the flowers +That open now their choisest bosomed smells, +Reserved from night, and kept for thee in store. +So cheered he his fair spouse, and she was cheered; +But silently a gentle tear let fall +From either eye, and wiped them with her hair; +Two other precious drops that ready stood, +Each in their crystal sluice, he ere they fell +Kissed, as the gracious signs of sweet remorse +And pious awe, that feared to have offended. +So all was cleared, and to the field they haste. +But first, from under shady arborous roof +Soon as they forth were come to open sight +Of day-spring, and the sun, who, scarce up-risen, +With wheels yet hovering o'er the ocean-brim, +Shot parallel to the earth his dewy ray, +Discovering in wide landskip all the east +Of Paradise and Eden's happy plains, +Lowly they bowed adoring, and began +Their orisons, each morning duly paid +In various style; for neither various style +Nor holy rapture wanted they to praise +Their Maker, in fit strains pronounced, or sung +Unmeditated; such prompt eloquence +Flowed from their lips, in prose or numerous verse, +More tuneable than needed lute or harp +To add more sweetness; and they thus began. +These are thy glorious works, Parent of good, +Almighty! Thine this universal frame, +Thus wonderous fair; Thyself how wonderous then! +Unspeakable, who sitst above these heavens +To us invisible, or dimly seen +In these thy lowest works; yet these declare +Thy goodness beyond thought, and power divine. +Speak, ye who best can tell, ye sons of light, +Angels; for ye behold him, and with songs +And choral symphonies, day without night, +Circle his throne rejoicing; ye in Heaven +On Earth join all ye Creatures to extol +Him first, him last, him midst, and without end. +Fairest of stars, last in the train of night, +If better thou belong not to the dawn, +Sure pledge of day, that crownest the smiling morn +With thy bright circlet, praise him in thy sphere, +While day arises, that sweet hour of prime. +Thou Sun, of this great world both eye and soul, +Acknowledge him thy greater; sound his praise +In thy eternal course, both when thou climbest, +And when high noon hast gained, and when thou fallest. +Moon, that now meetest the orient sun, now flyest, +With the fixed Stars, fixed in their orb that flies; +And ye five other wandering Fires, that move +In mystick dance not without song, resound +His praise, who out of darkness called up light. +Air, and ye Elements, the eldest birth +Of Nature's womb, that in quaternion run +Perpetual circle, multiform; and mix +And nourish all things; let your ceaseless change +Vary to our great Maker still new praise. +Ye Mists and Exhalations, that now rise +From hill or steaming lake, dusky or gray, +Till the sun paint your fleecy skirts with gold, +In honour to the world's great Author rise; +Whether to deck with clouds the uncoloured sky, +Or wet the thirsty earth with falling showers, +Rising or falling still advance his praise. +His praise, ye Winds, that from four quarters blow, +Breathe soft or loud; and, wave your tops, ye Pines, +With every plant, in sign of worship wave. +Fountains, and ye that warble, as ye flow, +Melodious murmurs, warbling tune his praise. +Join voices, all ye living Souls: Ye Birds, +That singing up to Heaven-gate ascend, +Bear on your wings and in your notes his praise. +Ye that in waters glide, and ye that walk +The earth, and stately tread, or lowly creep; +Witness if I be silent, morn or even, +To hill, or valley, fountain, or fresh shade, +Made vocal by my song, and taught his praise. +Hail, universal Lord, be bounteous still +To give us only good; and if the night +Have gathered aught of evil, or concealed, +Disperse it, as now light dispels the dark! +So prayed they innocent, and to their thoughts +Firm peace recovered soon, and wonted calm. +On to their morning's rural work they haste, +Among sweet dews and flowers; where any row +Of fruit-trees over-woody reached too far +Their pampered boughs, and needed hands to check +Fruitless embraces: or they led the vine +To wed her elm; she, spoused, about him twines +Her marriageable arms, and with him brings +Her dower, the adopted clusters, to adorn +His barren leaves. Them thus employed beheld +With pity Heaven's high King, and to him called +Raphael, the sociable Spirit, that deigned +To travel with Tobias, and secured +His marriage with the seventimes-wedded maid. +Raphael, said he, thou hearest what stir on Earth +Satan, from Hell 'scaped through the darksome gulf, +Hath raised in Paradise; and how disturbed +This night the human pair; how he designs +In them at once to ruin all mankind. +Go therefore, half this day as friend with friend +Converse with Adam, in what bower or shade +Thou findest him from the heat of noon retired, +To respite his day-labour with repast, +Or with repose; and such discourse bring on, +As may advise him of his happy state, +Happiness in his power left free to will, +Left to his own free will, his will though free, +Yet mutable; whence warn him to beware +He swerve not, too secure: Tell him withal +His danger, and from whom; what enemy, +Late fallen himself from Heaven, is plotting now +The fall of others from like state of bliss; +By violence? no, for that shall be withstood; +But by deceit and lies: This let him know, +Lest, wilfully transgressing, he pretend +Surprisal, unadmonished, unforewarned. +So spake the Eternal Father, and fulfilled +All justice: Nor delayed the winged Saint +After his charge received; but from among +Thousand celestial Ardours, where he stood +Veiled with his gorgeous wings, up springing light, +Flew through the midst of Heaven; the angelick quires, +On each hand parting, to his speed gave way +Through all the empyreal road; till, at the gate +Of Heaven arrived, the gate self-opened wide +On golden hinges turning, as by work +Divine the sovran Architect had framed. +From hence no cloud, or, to obstruct his sight, +Star interposed, however small he sees, +Not unconformed to other shining globes, +Earth, and the garden of God, with cedars crowned +Above all hills. As when by night the glass +Of Galileo, less assured, observes +Imagined lands and regions in the moon: +Or pilot, from amidst the Cyclades +Delos or Samos first appearing, kens +A cloudy spot. Down thither prone in flight +He speeds, and through the vast ethereal sky +Sails between worlds and worlds, with steady wing +Now on the polar winds, then with quick fan +Winnows the buxom air; till, within soar +Of towering eagles, to all the fowls he seems +A phoenix, gazed by all as that sole bird, +When, to enshrine his reliques in the Sun's +Bright temple, to Egyptian Thebes he flies. +At once on the eastern cliff of Paradise +He lights, and to his proper shape returns +A Seraph winged: Six wings he wore, to shade +His lineaments divine; the pair that clad +Each shoulder broad, came mantling o'er his breast +With regal ornament; the middle pair +Girt like a starry zone his waist, and round +Skirted his loins and thighs with downy gold +And colours dipt in Heaven; the third his feet +Shadowed from either heel with feathered mail, +Sky-tinctured grain. Like Maia's son he stood, +And shook his plumes, that heavenly fragrance filled +The circuit wide. Straight knew him all the bands +Of Angels under watch; and to his state, +And to his message high, in honour rise; +For on some message high they guessed him bound. +Their glittering tents he passed, and now is come +Into the blissful field, through groves of myrrh, +And flowering odours, cassia, nard, and balm; +A wilderness of sweets; for Nature here +Wantoned as in her prime, and played at will +Her virgin fancies pouring forth more sweet, +Wild above rule or art, enormous bliss. +Him through the spicy forest onward come +Adam discerned, as in the door he sat +Of his cool bower, while now the mounted sun +Shot down direct his fervid rays to warm +Earth's inmost womb, more warmth than Adam needs: +And Eve within, due at her hour prepared +For dinner savoury fruits, of taste to please +True appetite, and not disrelish thirst +Of nectarous draughts between, from milky stream, +Berry or grape: To whom thus Adam called. +Haste hither, Eve, and worth thy sight behold +Eastward among those trees, what glorious shape +Comes this way moving; seems another morn +Risen on mid-noon; some great behest from Heaven +To us perhaps he brings, and will vouchsafe +This day to be our guest. But go with speed, +And, what thy stores contain, bring forth, and pour +Abundance, fit to honour and receive +Our heavenly stranger: Well we may afford +Our givers their own gifts, and large bestow +From large bestowed, where Nature multiplies +Her fertile growth, and by disburthening grows +More fruitful, which instructs us not to spare. +To whom thus Eve. Adam, earth's hallowed mould, +Of God inspired! small store will serve, where store, +All seasons, ripe for use hangs on the stalk; +Save what by frugal storing firmness gains +To nourish, and superfluous moist consumes: +But I will haste, and from each bough and brake, +Each plant and juciest gourd, will pluck such choice +To entertain our Angel-guest, as he +Beholding shall confess, that here on Earth +God hath dispensed his bounties as in Heaven. +So saying, with dispatchful looks in haste +She turns, on hospitable thoughts intent +What choice to choose for delicacy best, +What order, so contrived as not to mix +Tastes, not well joined, inelegant, but bring +Taste after taste upheld with kindliest change; +Bestirs her then, and from each tender stalk +Whatever Earth, all-bearing mother, yields +In India East or West, or middle shore +In Pontus or the Punick coast, or where +Alcinous reigned, fruit of all kinds, in coat +Rough, or smooth rind, or bearded husk, or shell, +She gathers, tribute large, and on the board +Heaps with unsparing hand; for drink the grape +She crushes, inoffensive must, and meaths +From many a berry, and from sweet kernels pressed +She tempers dulcet creams; nor these to hold +Wants her fit vessels pure; then strows the ground +With rose and odours from the shrub unfumed. +Mean while our primitive great sire, to meet +His God-like guest, walks forth, without more train +Accompanied than with his own complete +Perfections; in himself was all his state, +More solemn than the tedious pomp that waits +On princes, when their rich retinue long +Of horses led, and grooms besmeared with gold, +Dazzles the croud, and sets them all agape. +Nearer his presence Adam, though not awed, +Yet with submiss approach and reverence meek, +As to a superiour nature bowing low, +Thus said. Native of Heaven, for other place +None can than Heaven such glorious shape contain; +Since, by descending from the thrones above, +Those happy places thou hast deigned a while +To want, and honour these, vouchsafe with us +Two only, who yet by sovran gift possess +This spacious ground, in yonder shady bower +To rest; and what the garden choicest bears +To sit and taste, till this meridian heat +Be over, and the sun more cool decline. +Whom thus the angelick Virtue answered mild. +Adam, I therefore came; nor art thou such +Created, or such place hast here to dwell, +As may not oft invite, though Spirits of Heaven, +To visit thee; lead on then where thy bower +O'ershades; for these mid-hours, till evening rise, +I have at will. So to the sylvan lodge +They came, that like Pomona's arbour smiled, +With flowerets decked, and fragrant smells; but Eve, +Undecked save with herself, more lovely fair +Than Wood-Nymph, or the fairest Goddess feigned +Of three that in mount Ida naked strove, +Stood to entertain her guest from Heaven; no veil +She needed, virtue-proof; no thought infirm +Altered her cheek. On whom the Angel Hail +Bestowed, the holy salutation used +Long after to blest Mary, second Eve. +Hail, Mother of Mankind, whose fruitful womb +Shall fill the world more numerous with thy sons, +Than with these various fruits the trees of God +Have heaped this table!--Raised of grassy turf +Their table was, and mossy seats had round, +And on her ample square from side to side +All autumn piled, though spring and autumn here +Danced hand in hand. A while discourse they hold; +No fear lest dinner cool; when thus began +Our author. Heavenly stranger, please to taste +These bounties, which our Nourisher, from whom +All perfect good, unmeasured out, descends, +To us for food and for delight hath caused +The earth to yield; unsavoury food perhaps +To spiritual natures; only this I know, +That one celestial Father gives to all. +To whom the Angel. Therefore what he gives +(Whose praise be ever sung) to Man in part +Spiritual, may of purest Spirits be found +No ingrateful food: And food alike those pure +Intelligential substances require, +As doth your rational; and both contain +Within them every lower faculty +Of sense, whereby they hear, see, smell, touch, taste, +Tasting concoct, digest, assimilate, +And corporeal to incorporeal turn. +For know, whatever was created, needs +To be sustained and fed: Of elements +The grosser feeds the purer, earth the sea, +Earth and the sea feed air, the air those fires +Ethereal, and as lowest first the moon; +Whence in her visage round those spots, unpurged +Vapours not yet into her substance turned. +Nor doth the moon no nourishment exhale +From her moist continent to higher orbs. +The sun that light imparts to all, receives +From all his alimental recompence +In humid exhalations, and at even +Sups with the ocean. Though in Heaven the trees +Of life ambrosial fruitage bear, and vines +Yield nectar; though from off the boughs each morn +We brush mellifluous dews, and find the ground +Covered with pearly grain: Yet God hath here +Varied his bounty so with new delights, +As may compare with Heaven; and to taste +Think not I shall be nice. So down they sat, +And to their viands fell; nor seemingly +The Angel, nor in mist, the common gloss +Of Theologians; but with keen dispatch +Of real hunger, and concoctive heat +To transubstantiate: What redounds, transpires +Through Spirits with ease; nor wonder;if by fire +Of sooty coal the empirick alchemist +Can turn, or holds it possible to turn, +Metals of drossiest ore to perfect gold, +As from the mine. Mean while at table Eve +Ministered naked, and their flowing cups +With pleasant liquours crowned: O innocence +Deserving Paradise! if ever, then, +Then had the sons of God excuse to have been +Enamoured at that sight; but in those hearts +Love unlibidinous reigned, nor jealousy +Was understood, the injured lover's hell. +Thus when with meats and drinks they had sufficed, +Not burdened nature, sudden mind arose +In Adam, not to let the occasion pass +Given him by this great conference to know +Of things above his world, and of their being +Who dwell in Heaven, whose excellence he saw +Transcend his own so far; whose radiant forms, +Divine effulgence, whose high power, so far +Exceeded human; and his wary speech +Thus to the empyreal minister he framed. +Inhabitant with God, now know I well +Thy favour, in this honour done to Man; +Under whose lowly roof thou hast vouchsafed +To enter, and these earthly fruits to taste, +Food not of Angels, yet accepted so, +As that more willingly thou couldst not seem +At Heaven's high feasts to have fed: yet what compare +To whom the winged Hierarch replied. +O Adam, One Almighty is, from whom +All things proceed, and up to him return, +If not depraved from good, created all +Such to perfection, one first matter all, +Endued with various forms, various degrees +Of substance, and, in things that live, of life; +But more refined, more spiritous, and pure, +As nearer to him placed, or nearer tending +Each in their several active spheres assigned, +Till body up to spirit work, in bounds +Proportioned to each kind. So from the root +Springs lighter the green stalk, from thence the leaves +More aery, last the bright consummate flower +Spirits odorous breathes: flowers and their fruit, +Man's nourishment, by gradual scale sublimed, +To vital spirits aspire, to animal, +To intellectual; give both life and sense, +Fancy and understanding; whence the soul +Reason receives, and reason is her being, +Discursive, or intuitive; discourse +Is oftest yours, the latter most is ours, +Differing but in degree, of kind the same. +Wonder not then, what God for you saw good +If I refuse not, but convert, as you +To proper substance. Time may come, when Men +With Angels may participate, and find +No inconvenient diet, nor too light fare; +And from these corporal nutriments perhaps +Your bodies may at last turn all to spirit, +Improved by tract of time, and, winged, ascend +Ethereal, as we; or may, at choice, +Here or in heavenly Paradises dwell; +If ye be found obedient, and retain +Unalterably firm his love entire, +Whose progeny you are. Mean while enjoy +Your fill what happiness this happy state +Can comprehend, incapable of more. +To whom the patriarch of mankind replied. +O favourable Spirit, propitious guest, +Well hast thou taught the way that might direct +Our knowledge, and the scale of nature set +From center to circumference; whereon, +In contemplation of created things, +By steps we may ascend to God. But say, +What meant that caution joined, If ye be found +Obedient? Can we want obedience then +To him, or possibly his love desert, +Who formed us from the dust and placed us here +Full to the utmost measure of what bliss +Human desires can seek or apprehend? +To whom the Angel. Son of Heaven and Earth, +Attend! That thou art happy, owe to God; +That thou continuest such, owe to thyself, +That is, to thy obedience; therein stand. +This was that caution given thee; be advised. +God made thee perfect, not immutable; +And good he made thee, but to persevere +He left it in thy power; ordained thy will +By nature free, not over-ruled by fate +Inextricable, or strict necessity: +Our voluntary service he requires, +Not our necessitated; such with him +Finds no acceptance, nor can find; for how +Can hearts, not free, be tried whether they serve +Willing or no, who will but what they must +By destiny, and can no other choose? +Myself, and all the angelick host, that stand +In sight of God, enthroned, our happy state +Hold, as you yours, while our obedience holds; +On other surety none: Freely we serve, +Because we freely love, as in our will +To love or not; in this we stand or fall: +And some are fallen, to disobedience fallen, +And so from Heaven to deepest Hell; O fall +From what high state of bliss, into what woe! +To whom our great progenitor. Thy words +Attentive, and with more delighted ear, +Divine instructer, I have heard, than when +Cherubick songs by night from neighbouring hills +Aereal musick send: Nor knew I not +To be both will and deed created free; +Yet that we never shall forget to love +Our Maker, and obey him whose command +Single is yet so just, my constant thoughts +Assured me, and still assure: Though what thou tellest +Hath passed in Heaven, some doubt within me move, +But more desire to hear, if thou consent, +The full relation, which must needs be strange, +Worthy of sacred silence to be heard; +And we have yet large day, for scarce the sun +Hath finished half his journey, and scarce begins +His other half in the great zone of Heaven. +Thus Adam made request; and Raphael, +After short pause assenting, thus began. +High matter thou enjoinest me, O prime of men, +Sad task and hard: For how shall I relate +To human sense the invisible exploits +Of warring Spirits? how, without remorse, +The ruin of so many glorious once +And perfect while they stood? how last unfold +The secrets of another world, perhaps +Not lawful to reveal? yet for thy good +This is dispensed; and what surmounts the reach +Of human sense, I shall delineate so, +By likening spiritual to corporal forms, +As may express them best; though what if Earth +Be but a shadow of Heaven, and things therein +Each to other like, more than on earth is thought? +As yet this world was not, and Chaos wild +Reigned where these Heavens now roll, where Earth now rests +Upon her center poised; when on a day +(For time, though in eternity, applied +To motion, measures all things durable +By present, past, and future,) on such day +As Heaven's great year brings forth, the empyreal host +Of Angels by imperial summons called, +Innumerable before the Almighty's throne +Forthwith, from all the ends of Heaven, appeared +Under their Hierarchs in orders bright: +Ten thousand thousand ensigns high advanced, +Standards and gonfalons 'twixt van and rear +Stream in the air, and for distinction serve +Of hierarchies, of orders, and degrees; +Or in their glittering tissues bear imblazed +Holy memorials, acts of zeal and love +Recorded eminent. Thus when in orbs +Of circuit inexpressible they stood, +Orb within orb, the Father Infinite, +By whom in bliss imbosomed sat the Son, +Amidst as from a flaming mount, whose top +Brightness had made invisible, thus spake. +Hear, all ye Angels, progeny of light, +Thrones, Dominations, Princedoms, Virtues, Powers; +Hear my decree, which unrevoked shall stand. +This day I have begot whom I declare +My only Son, and on this holy hill +Him have anointed, whom ye now behold +At my right hand; your head I him appoint; +And by myself have sworn, to him shall bow +All knees in Heaven, and shall confess him Lord: +Under his great vice-gerent reign abide +United, as one individual soul, +For ever happy: Him who disobeys, +Me disobeys, breaks union, and that day, +Cast out from God and blessed vision, falls +Into utter darkness, deep ingulfed, his place +Ordained without redemption, without end. +So spake the Omnipotent, and with his words +All seemed well pleased; all seemed, but were not all. +That day, as other solemn days, they spent +In song and dance about the sacred hill; +Mystical dance, which yonder starry sphere +Of planets, and of fixed, in all her wheels +Resembles nearest, mazes intricate, +Eccentrick, intervolved, yet regular +Then most, when most irregular they seem; +And in their motions harmony divine +So smooths her charming tones, that God's own ear +Listens delighted. Evening now approached, +(For we have also our evening and our morn, +We ours for change delectable, not need;) +Forthwith from dance to sweet repast they turn +Desirous; all in circles as they stood, +Tables are set, and on a sudden piled +With Angels food, and rubied nectar flows +In pearl, in diamond, and massy gold, +Fruit of delicious vines, the growth of Heaven. +On flowers reposed, and with fresh flowerets crowned, +They eat, they drink, and in communion sweet +Quaff immortality and joy, secure +Of surfeit, where full measure only bounds +Excess, before the all-bounteous King, who showered +With copious hand, rejoicing in their joy. +Now when ambrosial night with clouds exhaled +From that high mount of God, whence light and shade +Spring both, the face of brightest Heaven had changed +To grateful twilight, (for night comes not there +In darker veil,) and roseat dews disposed +All but the unsleeping eyes of God to rest; +Wide over all the plain, and wider far +Than all this globous earth in plain outspread, +(Such are the courts of God) the angelick throng, +Dispersed in bands and files, their camp extend +By living streams among the trees of life, +Pavilions numberless, and sudden reared, +Celestial tabernacles, where they slept +Fanned with cool winds; save those, who, in their course, +Melodious hymns about the sovran throne +Alternate all night long: but not so waked +Satan; so call him now, his former name +Is heard no more in Heaven; he of the first, +If not the first Arch-Angel, great in power, +In favour and pre-eminence, yet fraught +With envy against the Son of God, that day +Honoured by his great Father, and proclaimed +Messiah King anointed, could not bear +Through pride that sight, and thought himself impaired. +Deep malice thence conceiving and disdain, +Soon as midnight brought on the dusky hour +Friendliest to sleep and silence, he resolved +With all his legions to dislodge, and leave +Unworshipt, unobeyed, the throne supreme, +Contemptuous; and his next subordinate +Awakening, thus to him in secret spake. +Sleepest thou, Companion dear? What sleep can close +Thy eye-lids? and rememberest what decree +Of yesterday, so late hath passed the lips +Of Heaven's Almighty. Thou to me thy thoughts +Wast wont, I mine to thee was wont to impart; +Both waking we were one; how then can now +Thy sleep dissent? New laws thou seest imposed; +New laws from him who reigns, new minds may raise +In us who serve, new counsels to debate +What doubtful may ensue: More in this place +To utter is not safe. Assemble thou +Of all those myriads which we lead the chief; +Tell them, that by command, ere yet dim night +Her shadowy cloud withdraws, I am to haste, +And all who under me their banners wave, +Homeward, with flying march, where we possess +The quarters of the north; there to prepare +Fit entertainment to receive our King, +The great Messiah, and his new commands, +Who speedily through all the hierarchies +Intends to pass triumphant, and give laws. +So spake the false Arch-Angel, and infused +Bad influence into the unwary breast +Of his associate: He together calls, +Or several one by one, the regent Powers, +Under him Regent; tells, as he was taught, +That the Most High commanding, now ere night, +Now ere dim night had disincumbered Heaven, +The great hierarchal standard was to move; +Tells the suggested cause, and casts between +Ambiguous words and jealousies, to sound +Or taint integrity: But all obeyed +The wonted signal, and superiour voice +Of their great Potentate; for great indeed +His name, and high was his degree in Heaven; +His countenance, as the morning-star that guides +The starry flock, allured them, and with lies +Drew after him the third part of Heaven's host. +Mean while the Eternal eye, whose sight discerns +Abstrusest thoughts, from forth his holy mount, +And from within the golden lamps that burn +Nightly before him, saw without their light +Rebellion rising; saw in whom, how spread +Among the sons of morn, what multitudes +Were banded to oppose his high decree; +And, smiling, to his only Son thus said. +Son, thou in whom my glory I behold +In full resplendence, Heir of all my might, +Nearly it now concerns us to be sure +Of our Omnipotence, and with what arms +We mean to hold what anciently we claim +Of deity or empire: Such a foe +Is rising, who intends to erect his throne +Equal to ours, throughout the spacious north; +Nor so content, hath in his thought to try +In battle, what our power is, or our right. +Let us advise, and to this hazard draw +With speed what force is left, and all employ +In our defence; lest unawares we lose +This our high place, our sanctuary, our hill. +To whom the Son with calm aspect and clear, +Lightning divine, ineffable, serene, +Made answer. Mighty Father, thou thy foes +Justly hast in derision, and, secure, +Laughest at their vain designs and tumults vain, +Matter to me of glory, whom their hate +Illustrates, when they see all regal power +Given me to quell their pride, and in event +Know whether I be dextrous to subdue +Thy rebels, or be found the worst in Heaven. +So spake the Son; but Satan, with his Powers, +Far was advanced on winged speed; an host +Innumerable as the stars of night, +Or stars of morning, dew-drops, which the sun +Impearls on every leaf and every flower. +Regions they passed, the mighty regencies +Of Seraphim, and Potentates, and Thrones, +In their triple degrees; regions to which +All thy dominion, Adam, is no more +Than what this garden is to all the earth, +And all the sea, from one entire globose +Stretched into longitude; which having passed, +At length into the limits of the north +They came; and Satan to his royal seat +High on a hill, far blazing, as a mount +Raised on a mount, with pyramids and towers +From diamond quarries hewn, and rocks of gold; +The palace of great Lucifer, (so call +That structure in the dialect of men +Interpreted,) which not long after, he +Affecting all equality with God, +In imitation of that mount whereon +Messiah was declared in sight of Heaven, +The Mountain of the Congregation called; +For thither he assembled all his train, +Pretending so commanded to consult +About the great reception of their King, +Thither to come, and with calumnious art +Of counterfeited truth thus held their ears. +Thrones, Dominations, Princedoms, Virtues, Powers; +If these magnifick titles yet remain +Not merely titular, since by decree +Another now hath to himself engrossed +All power, and us eclipsed under the name +Of King anointed, for whom all this haste +Of midnight-march, and hurried meeting here, +This only to consult how we may best, +With what may be devised of honours new, +Receive him coming to receive from us +Knee-tribute yet unpaid, prostration vile! +Too much to one! but double how endured, +To one, and to his image now proclaimed? +But what if better counsels might erect +Our minds, and teach us to cast off this yoke? +Will ye submit your necks, and choose to bend +The supple knee? Ye will not, if I trust +To know ye right, or if ye know yourselves +Natives and sons of Heaven possessed before +By none; and if not equal all, yet free, +Equally free; for orders and degrees +Jar not with liberty, but well consist. +Who can in reason then, or right, assume +Monarchy over such as live by right +His equals, if in power and splendour less, +In freedom equal? or can introduce +Law and edict on us, who without law +Err not? much less for this to be our Lord, +And look for adoration, to the abuse +Of those imperial titles, which assert +Our being ordained to govern, not to serve. +Thus far his bold discourse without controul +Had audience; when among the Seraphim +Abdiel, than whom none with more zeal adored +The Deity, and divine commands obeyed, +Stood up, and in a flame of zeal severe +The current of his fury thus opposed. +O argument blasphemous, false, and proud! +Words which no ear ever to hear in Heaven +Expected, least of all from thee, Ingrate, +In place thyself so high above thy peers. +Canst thou with impious obloquy condemn +The just decree of God, pronounced and sworn, +That to his only Son, by right endued +With regal scepter, every soul in Heaven +Shall bend the knee, and in that honour due +Confess him rightful King? unjust, thou sayest, +Flatly unjust, to bind with laws the free, +And equal over equals to let reign, +One over all with unsucceeded power. +Shalt thou give law to God? shalt thou dispute +With him the points of liberty, who made +Thee what thou art, and formed the Powers of Heaven +Such as he pleased, and circumscribed their being? +Yet, by experience taught, we know how good, +And of our good and of our dignity +How provident he is; how far from thought +To make us less, bent rather to exalt +Our happy state, under one head more near +United. But to grant it thee unjust, +That equal over equals monarch reign: +Thyself, though great and glorious, dost thou count, +Or all angelick nature joined in one, +Equal to him begotten Son? by whom, +As by his Word, the Mighty Father made +All things, even thee; and all the Spirits of Heaven +By him created in their bright degrees, +Crowned them with glory, and to their glory named +Thrones, Dominations, Princedoms, Virtues, Powers, +Essential Powers; nor by his reign obscured, +But more illustrious made; since he the head +One of our number thus reduced becomes; +His laws our laws; all honour to him done +Returns our own. Cease then this impious rage, +And tempt not these; but hasten to appease +The incensed Father, and the incensed Son, +While pardon may be found in time besought. +So spake the fervent Angel; but his zeal +None seconded, as out of season judged, +Or singular and rash: Whereat rejoiced +The Apostate, and, more haughty, thus replied. +That we were formed then sayest thou? and the work +Of secondary hands, by task transferred +From Father to his Son? strange point and new! +Doctrine which we would know whence learned: who saw +When this creation was? rememberest thou +Thy making, while the Maker gave thee being? +We know no time when we were not as now; +Know none before us, self-begot, self-raised +By our own quickening power, when fatal course +Had circled his full orb, the birth mature +Of this our native Heaven, ethereal sons. +Our puissance is our own; our own right hand +Shall teach us highest deeds, by proof to try +Who is our equal: Then thou shalt behold +Whether by supplication we intend +Address, and to begirt the almighty throne +Beseeching or besieging. This report, +These tidings carry to the anointed King; +And fly, ere evil intercept thy flight. +He said; and, as the sound of waters deep, +Hoarse murmur echoed to his words applause +Through the infinite host; nor less for that +The flaming Seraph fearless, though alone +Encompassed round with foes, thus answered bold. +O alienate from God, O Spirit accursed, +Forsaken of all good! I see thy fall +Determined, and thy hapless crew involved +In this perfidious fraud, contagion spread +Both of thy crime and punishment: Henceforth +No more be troubled how to quit the yoke +Of God's Messiah; those indulgent laws +Will not be now vouchsafed; other decrees +Against thee are gone forth without recall; +That golden scepter, which thou didst reject, +Is now an iron rod to bruise and break +Thy disobedience. Well thou didst advise; +Yet not for thy advice or threats I fly +These wicked tents devoted, lest the wrath +Impendent, raging into sudden flame, +Distinguish not: For soon expect to feel +His thunder on thy head, devouring fire. +Then who created thee lamenting learn, +When who can uncreate thee thou shalt know. +So spake the Seraph Abdiel, faithful found +Among the faithless, faithful only he; +Among innumerable false, unmoved, +Unshaken, unseduced, unterrified, +His loyalty he kept, his love, his zeal; +Nor number, nor example, with him wrought +To swerve from truth, or change his constant mind, +Though single. From amidst them forth he passed, +Long way through hostile scorn, which he sustained +Superiour, nor of violence feared aught; +And, with retorted scorn, his back he turned +On those proud towers to swift destruction doomed. + + + +Book VI + + +All night the dreadless Angel, unpursued, +Through Heaven's wide champain held his way; till Morn, +Waked by the circling Hours, with rosy hand +Unbarred the gates of light. There is a cave +Within the mount of God, fast by his throne, +Where light and darkness in perpetual round +Lodge and dislodge by turns, which makes through Heaven +Grateful vicissitude, like day and night; +Light issues forth, and at the other door +Obsequious darkness enters, till her hour +To veil the Heaven, though darkness there might well +Seem twilight here: And now went forth the Morn +Such as in highest Heaven arrayed in gold +Empyreal; from before her vanished Night, +Shot through with orient beams; when all the plain +Covered with thick embattled squadrons bright, +Chariots, and flaming arms, and fiery steeds, +Reflecting blaze on blaze, first met his view: +War he perceived, war in procinct; and found +Already known what he for news had thought +To have reported: Gladly then he mixed +Among those friendly Powers, who him received +With joy and acclamations loud, that one, +That of so many myriads fallen, yet one +Returned not lost. On to the sacred hill +They led him high applauded, and present +Before the seat supreme; from whence a voice, +From midst a golden cloud, thus mild was heard. +Servant of God. Well done; well hast thou fought +The better fight, who single hast maintained +Against revolted multitudes the cause +Of truth, in word mightier than they in arms; +And for the testimony of truth hast borne +Universal reproach, far worse to bear +Than violence; for this was all thy care +To stand approved in sight of God, though worlds +Judged thee perverse: The easier conquest now +Remains thee, aided by this host of friends, +Back on thy foes more glorious to return, +Than scorned thou didst depart; and to subdue +By force, who reason for their law refuse, +Right reason for their law, and for their King +Messiah, who by right of merit reigns. +Go, Michael, of celestial armies prince, +And thou, in military prowess next, +Gabriel, lead forth to battle these my sons +Invincible; lead forth my armed Saints, +By thousands and by millions, ranged for fight, +Equal in number to that Godless crew +Rebellious: Them with fire and hostile arms +Fearless assault; and, to the brow of Heaven +Pursuing, drive them out from God and bliss, +Into their place of punishment, the gulf +Of Tartarus, which ready opens wide +His fiery Chaos to receive their fall. +So spake the Sovran Voice, and clouds began +To darken all the hill, and smoke to roll +In dusky wreaths, reluctant flames, the sign +Of wrath awaked; nor with less dread the loud +Ethereal trumpet from on high 'gan blow: +At which command the Powers militant, +That stood for Heaven, in mighty quadrate joined +Of union irresistible, moved on +In silence their bright legions, to the sound +Of instrumental harmony, that breathed +Heroick ardour to adventurous deeds +Under their God-like leaders, in the cause +Of God and his Messiah. On they move +Indissolubly firm; nor obvious hill, +Nor straitening vale, nor wood, nor stream, divides +Their perfect ranks; for high above the ground +Their march was, and the passive air upbore +Their nimble tread; as when the total kind +Of birds, in orderly array on wing, +Came summoned over Eden to receive +Their names of thee; so over many a tract +Of Heaven they marched, and many a province wide, +Tenfold the length of this terrene: At last, +Far in the horizon to the north appeared +From skirt to skirt a fiery region, stretched +In battailous aspect, and nearer view +Bristled with upright beams innumerable +Of rigid spears, and helmets thronged, and shields +Various, with boastful argument portrayed, +The banded Powers of Satan hasting on +With furious expedition; for they weened +That self-same day, by fight or by surprise, +To win the mount of God, and on his throne +To set the Envier of his state, the proud +Aspirer; but their thoughts proved fond and vain +In the mid way: Though strange to us it seemed +At first, that Angel should with Angel war, +And in fierce hosting meet, who wont to meet +So oft in festivals of joy and love +Unanimous, as sons of one great Sire, +Hymning the Eternal Father: But the shout +Of battle now began, and rushing sound +Of onset ended soon each milder thought. +High in the midst, exalted as a God, +The Apostate in his sun-bright chariot sat, +Idol of majesty divine, enclosed +With flaming Cherubim, and golden shields; +Then lighted from his gorgeous throne, for now +"twixt host and host but narrow space was left, +A dreadful interval, and front to front +Presented stood in terrible array +Of hideous length: Before the cloudy van, +On the rough edge of battle ere it joined, +Satan, with vast and haughty strides advanced, +Came towering, armed in adamant and gold; +Abdiel that sight endured not, where he stood +Among the mightiest, bent on highest deeds, +And thus his own undaunted heart explores. +O Heaven! that such resemblance of the Highest +Should yet remain, where faith and realty +Remain not: Wherefore should not strength and might +There fail where virtue fails, or weakest prove +Where boldest, though to fight unconquerable? +His puissance, trusting in the Almighty's aid, +I mean to try, whose reason I have tried +Unsound and false; nor is it aught but just, +That he, who in debate of truth hath won, +Should win in arms, in both disputes alike +Victor; though brutish that contest and foul, +When reason hath to deal with force, yet so +Most reason is that reason overcome. +So pondering, and from his armed peers +Forth stepping opposite, half-way he met +His daring foe, at this prevention more +Incensed, and thus securely him defied. +Proud, art thou met? thy hope was to have reached +The highth of thy aspiring unopposed, +The throne of God unguarded, and his side +Abandoned, at the terrour of thy power +Or potent tongue: Fool!not to think how vain +Against the Omnipotent to rise in arms; +Who out of smallest things could, without end, +Have raised incessant armies to defeat +Thy folly; or with solitary hand +Reaching beyond all limit, at one blow, +Unaided, could have finished thee, and whelmed +Thy legions under darkness: But thou seest +All are not of thy train; there be, who faith +Prefer, and piety to God, though then +To thee not visible, when I alone +Seemed in thy world erroneous to dissent +From all: My sect thou seest;now learn too late +How few sometimes may know, when thousands err. +Whom the grand foe, with scornful eye askance, +Thus answered. Ill for thee, but in wished hour +Of my revenge, first sought for, thou returnest +From flight, seditious Angel! to receive +Thy merited reward, the first assay +Of this right hand provoked, since first that tongue, +Inspired with contradiction, durst oppose +A third part of the Gods, in synod met +Their deities to assert; who, while they feel +Vigour divine within them, can allow +Omnipotence to none. But well thou comest +Before thy fellows, ambitious to win +From me some plume, that thy success may show +Destruction to the rest: This pause between, +(Unanswered lest thou boast) to let thee know, +At first I thought that Liberty and Heaven +To heavenly souls had been all one; but now +I see that most through sloth had rather serve, +Ministring Spirits, trained up in feast and song! +Such hast thou armed, the minstrelsy of Heaven, +Servility with freedom to contend, +As both their deeds compared this day shall prove. +To whom in brief thus Abdiel stern replied. +Apostate! still thou errest, nor end wilt find +Of erring, from the path of truth remote: +Unjustly thou depravest it with the name +Of servitude, to serve whom God ordains, +Or Nature: God and Nature bid the same, +When he who rules is worthiest, and excels +Them whom he governs. This is servitude, +To serve the unwise, or him who hath rebelled +Against his worthier, as thine now serve thee, +Thyself not free, but to thyself enthralled; +Yet lewdly darest our ministring upbraid. +Reign thou in Hell, thy kingdom; let me serve +In Heaven God ever blest, and his divine +Behests obey, worthiest to be obeyed; +Yet chains in Hell, not realms, expect: Mean while +From me returned, as erst thou saidst, from flight, +This greeting on thy impious crest receive. +So saying, a noble stroke he lifted high, +Which hung not, but so swift with tempest fell +On the proud crest of Satan, that no sight, +Nor motion of swift thought, less could his shield, +Such ruin intercept: Ten paces huge +He back recoiled; the tenth on bended knee +His massy spear upstaid; as if on earth +Winds under ground, or waters forcing way, +Sidelong had pushed a mountain from his seat, +Half sunk with all his pines. Amazement seised +The rebel Thrones, but greater rage, to see +Thus foiled their mightiest; ours joy filled, and shout, +Presage of victory, and fierce desire +Of battle: Whereat Michael bid sound +The Arch-Angel trumpet; through the vast of Heaven +It sounded, and the faithful armies rung +Hosanna to the Highest: Nor stood at gaze +The adverse legions, nor less hideous joined +The horrid shock. Now storming fury rose, +And clamour such as heard in Heaven till now +Was never; arms on armour clashing brayed +Horrible discord, and the madding wheels +Of brazen chariots raged; dire was the noise +Of conflict; over head the dismal hiss +Of fiery darts in flaming vollies flew, +And flying vaulted either host with fire. +So under fiery cope together rushed +Both battles main, with ruinous assault +And inextinguishable rage. All Heaven +Resounded; and had Earth been then, all Earth +Had to her center shook. What wonder? when +Millions of fierce encountering Angels fought +On either side, the least of whom could wield +These elements, and arm him with the force +Of all their regions: How much more of power +Army against army numberless to raise +Dreadful combustion warring, and disturb, +Though not destroy, their happy native seat; +Had not the Eternal King Omnipotent, +From his strong hold of Heaven, high over-ruled +And limited their might; though numbered such +As each divided legion might have seemed +A numerous host; in strength each armed hand +A legion; led in fight, yet leader seemed +Each warriour single as in chief, expert +When to advance, or stand, or turn the sway +Of battle, open when, and when to close +The ridges of grim war: No thought of flight, +None of retreat, no unbecoming deed +That argued fear; each on himself relied, +As only in his arm the moment lay +Of victory: Deeds of eternal fame +Were done, but infinite; for wide was spread +That war and various; sometimes on firm ground +A standing fight, then, soaring on main wing, +Tormented all the air; all air seemed then +Conflicting fire. Long time in even scale +The battle hung; till Satan, who that day +Prodigious power had shown, and met in arms +No equal, ranging through the dire attack +Of fighting Seraphim confused, at length +Saw where the sword of Michael smote, and felled +Squadrons at once; with huge two-handed sway +Brandished aloft, the horrid edge came down +Wide-wasting; such destruction to withstand +He hasted, and opposed the rocky orb +Of tenfold adamant, his ample shield, +A vast circumference. At his approach +The great Arch-Angel from his warlike toil +Surceased, and glad, as hoping here to end +Intestine war in Heaven, the arch-foe subdued +Or captive dragged in chains, with hostile frown +And visage all inflamed first thus began. +Author of evil, unknown till thy revolt, +Unnamed in Heaven, now plenteous as thou seest +These acts of hateful strife, hateful to all, +Though heaviest by just measure on thyself, +And thy adherents: How hast thou disturbed +Heaven's blessed peace, and into nature brought +Misery, uncreated till the crime +Of thy rebellion! how hast thou instilled +Thy malice into thousands, once upright +And faithful, now proved false! But think not here +To trouble holy rest; Heaven casts thee out +From all her confines. Heaven, the seat of bliss, +Brooks not the works of violence and war. +Hence then, and evil go with thee along, +Thy offspring, to the place of evil, Hell; +Thou and thy wicked crew! there mingle broils, +Ere this avenging sword begin thy doom, +Or some more sudden vengeance, winged from God, +Precipitate thee with augmented pain. +So spake the Prince of Angels; to whom thus +The Adversary. Nor think thou with wind +Of aery threats to awe whom yet with deeds +Thou canst not. Hast thou turned the least of these +To flight, or if to fall, but that they rise +Unvanquished, easier to transact with me +That thou shouldst hope, imperious, and with threats +To chase me hence? err not, that so shall end +The strife which thou callest evil, but we style +The strife of glory; which we mean to win, +Or turn this Heaven itself into the Hell +Thou fablest; here however to dwell free, +If not to reign: Mean while thy utmost force, +And join him named Almighty to thy aid, +I fly not, but have sought thee far and nigh. +They ended parle, and both addressed for fight +Unspeakable; for who, though with the tongue +Of Angels, can relate, or to what things +Liken on earth conspicuous, that may lift +Human imagination to such highth +Of Godlike power? for likest Gods they seemed, +Stood they or moved, in stature, motion, arms, +Fit to decide the empire of great Heaven. +Now waved their fiery swords, and in the air +Made horrid circles; two broad suns their shields +Blazed opposite, while Expectation stood +In horrour: From each hand with speed retired, +Where erst was thickest fight, the angelick throng, +And left large field, unsafe within the wind +Of such commotion; such as, to set forth +Great things by small, if, nature's concord broke, +Among the constellations war were sprung, +Two planets, rushing from aspect malign +Of fiercest opposition, in mid sky +Should combat, and their jarring spheres confound. +Together both with next to almighty arm +Up-lifted imminent, one stroke they aimed +That might determine, and not need repeat, +As not of power at once; nor odds appeared +In might or swift prevention: But the sword +Of Michael from the armoury of God +Was given him tempered so, that neither keen +Nor solid might resist that edge: it met +The sword of Satan, with steep force to smite +Descending, and in half cut sheer; nor staid, +But with swift wheel reverse, deep entering, shared +All his right side: Then Satan first knew pain, +And writhed him to and fro convolved; so sore +The griding sword with discontinuous wound +Passed through him: But the ethereal substance closed, +Not long divisible; and from the gash +A stream of necturous humour issuing flowed +Sanguine, such as celestial Spirits may bleed, +And all his armour stained, ere while so bright. +Forthwith on all sides to his aid was run +By Angels many and strong, who interposed +Defence, while others bore him on their shields +Back to his chariot, where it stood retired +From off the files of war: There they him laid +Gnashing for anguish, and despite, and shame, +To find himself not matchless, and his pride +Humbled by such rebuke, so far beneath +His confidence to equal God in power. +Yet soon he healed; for Spirits that live throughout +Vital in every part, not as frail man +In entrails, heart of head, liver or reins, +Cannot but by annihilating die; +Nor in their liquid texture mortal wound +Receive, no more than can the fluid air: +All heart they live, all head, all eye, all ear, +All intellect, all sense; and, as they please, +They limb themselves, and colour, shape, or size +Assume, as?kikes them best, condense or rare. +Mean while in other parts like deeds deserved +Memorial, where the might of Gabriel fought, +And with fierce ensigns pierced the deep array +Of Moloch, furious king; who him defied, +And at his chariot-wheels to drag him bound +Threatened, nor from the Holy One of Heaven +Refrained his tongue blasphemous; but anon +Down cloven to the waist, with shattered arms +And uncouth pain fled bellowing. On each wing +Uriel, and Raphael, his vaunting foe, +Though huge, and in a rock of diamond armed, +Vanquished Adramelech, and Asmadai, +Two potent Thrones, that to be less than Gods +Disdained, but meaner thoughts learned in their flight, +Mangled with ghastly wounds through plate and mail. +Nor stood unmindful Abdiel to annoy +The atheist crew, but with redoubled blow +Ariel, and Arioch, and the violence +Of Ramiel scorched and blasted, overthrew. +I might relate of thousands, and their names +Eternize here on earth; but those elect +Angels, contented with their fame in Heaven, +Seek not the praise of men: The other sort, +In might though wonderous and in acts of war, +Nor of renown less eager, yet by doom +Cancelled from Heaven and sacred memory, +Nameless in dark oblivion let them dwell. +For strength from truth divided, and from just, +Illaudable, nought merits but dispraise +And ignominy; yet to glory aspires +Vain-glorious, and through infamy seeks fame: +Therefore eternal silence be their doom. +And now, their mightiest quelled, the battle swerved, +With many an inroad gored; deformed rout +Entered, and foul disorder; all the ground +With shivered armour strown, and on a heap +Chariot and charioteer lay overturned, +And fiery-foaming steeds; what stood, recoiled +O'er-wearied, through the faint Satanick host +Defensive scarce, or with pale fear surprised, +Then first with fear surprised, and sense of pain, +Fled ignominious, to such evil brought +By sin of disobedience; till that hour +Not liable to fear, or flight, or pain. +Far otherwise the inviolable Saints, +In cubick phalanx firm, advanced entire, +Invulnerable, impenetrably armed; +Such high advantages their innocence +Gave them above their foes; not to have sinned, +Not to have disobeyed; in fight they stood +Unwearied, unobnoxious to be pained +By wound, though from their place by violence moved, +Now Night her course began, and, over Heaven +Inducing darkness, grateful truce imposed, +And silence on the odious din of war: +Under her cloudy covert both retired, +Victor and vanquished: On the foughten field +Michael and his Angels prevalent +Encamping, placed in guard their watches round, +Cherubick waving fires: On the other part, +Satan with his rebellious disappeared, +Far in the dark dislodged; and, void of rest, +His potentates to council called by night; +And in the midst thus undismayed began. +O now in danger tried, now known in arms +Not to be overpowered, Companions dear, +Found worthy not of liberty alone, +Too mean pretence! but what we more affect, +Honour, dominion, glory, and renown; +Who have sustained one day in doubtful fight, +(And if one day, why not eternal days?) +What Heaven's Lord had powerfullest to send +Against us from about his throne, and judged +Sufficient to subdue us to his will, +But proves not so: Then fallible, it seems, +Of future we may deem him, though till now +Omniscient thought. True is, less firmly armed, +Some disadvantage we endured and pain, +Till now not known, but, known, as soon contemned; +Since now we find this our empyreal form +Incapable of mortal injury, +Imperishable, and, though pierced with wound, +Soon closing, and by native vigour healed. +Of evil then so small as easy think +The remedy; perhaps more valid arms, +Weapons more violent, when next we meet, +May serve to better us, and worse our foes, +Or equal what between us made the odds, +In nature none: If other hidden cause +Left them superiour, while we can preserve +Unhurt our minds, and understanding sound, +Due search and consultation will disclose. +He sat; and in the assembly next upstood +Nisroch, of Principalities the prime; +As one he stood escaped from cruel fight, +Sore toiled, his riven arms to havock hewn, +And cloudy in aspect thus answering spake. +Deliverer from new Lords, leader to free +Enjoyment of our right as Gods; yet hard +For Gods, and too unequal work we find, +Against unequal arms to fight in pain, +Against unpained, impassive; from which evil +Ruin must needs ensue; for what avails +Valour or strength, though matchless, quelled with pain +Which all subdues, and makes remiss the hands +Of mightiest? Sense of pleasure we may well +Spare out of life perhaps, and not repine, +But live content, which is the calmest life: +But pain is perfect misery, the worst +Of evils, and, excessive, overturns +All patience. He, who therefore can invent +With what more forcible we may offend +Our yet unwounded enemies, or arm +Ourselves with like defence, to me deserves +No less than for deliverance what we owe. +Whereto with look composed Satan replied. +Not uninvented that, which thou aright +Believest so main to our success, I bring. +Which of us who beholds the bright surface +Of this ethereous mould whereon we stand, +This continent of spacious Heaven, adorned +With plant, fruit, flower ambrosial, gems, and gold; +Whose eye so superficially surveys +These things, as not to mind from whence they grow +Deep under ground, materials dark and crude, +Of spiritous and fiery spume, till touched +With Heaven's ray, and tempered, they shoot forth +So beauteous, opening to the ambient light? +These in their dark nativity the deep +Shall yield us, pregnant with infernal flame; +Which, into hollow engines, long and round, +Thick rammed, at the other bore with touch of fire +Dilated and infuriate, shall send forth +From far, with thundering noise, among our foes +Such implements of mischief, as shall dash +To pieces, and o'erwhelm whatever stands +Adverse, that they shall fear we have disarmed +The Thunderer of his only dreaded bolt. +Nor long shall be our labour; yet ere dawn, +Effect shall end our wish. Mean while revive; +Abandon fear; to strength and counsel joined +Think nothing hard, much less to be despaired. +He ended, and his words their drooping cheer +Enlightened, and their languished hope revived. +The invention all admired, and each, how he +To be the inventer missed; so easy it seemed +Once found, which yet unfound most would have thought +Impossible: Yet, haply, of thy race +In future days, if malice should abound, +Some one intent on mischief, or inspired +With devilish machination, might devise +Like instrument to plague the sons of men +For sin, on war and mutual slaughter bent. +Forthwith from council to the work they flew; +None arguing stood; innumerable hands +Were ready; in a moment up they turned +Wide the celestial soil, and saw beneath +The originals of nature in their crude +Conception; sulphurous and nitrous foam +They found, they mingled, and, with subtle art, +Concocted and adusted they reduced +To blackest grain, and into store conveyed: +Part hidden veins digged up (nor hath this earth +Entrails unlike) of mineral and stone, +Whereof to found their engines and their balls +Of missive ruin; part incentive reed +Provide, pernicious with one touch to fire. +So all ere day-spring, under conscious night, +Secret they finished, and in order set, +With silent circumspection, unespied. +Now when fair morn orient in Heaven appeared, +Up rose the victor-Angels, and to arms +The matin trumpet sung: In arms they stood +Of golden panoply, refulgent host, +Soon banded; others from the dawning hills +Look round, and scouts each coast light-armed scour, +Each quarter to descry the distant foe, +Where lodged, or whither fled, or if for fight, +In motion or in halt: Him soon they met +Under spread ensigns moving nigh, in slow +But firm battalion; back with speediest sail +Zophiel, of Cherubim the swiftest wing, +Came flying, and in mid air aloud thus cried. +Arm, Warriours, arm for fight; the foe at hand, +Whom fled we thought, will save us long pursuit +This day; fear not his flight;so thick a cloud +He comes, and settled in his face I see +Sad resolution, and secure: Let each +His adamantine coat gird well, and each +Fit well his helm, gripe fast his orbed shield, +Borne even or high; for this day will pour down, +If I conjecture aught, no drizzling shower, +But rattling storm of arrows barbed with fire. +So warned he them, aware themselves, and soon +In order, quit of all impediment; +Instant without disturb they took alarm, +And onward moved embattled: When behold! +Not distant far with heavy pace the foe +Approaching gross and huge, in hollow cube +Training his devilish enginery, impaled +On every side with shadowing squadrons deep, +To hide the fraud. At interview both stood +A while; but suddenly at head appeared +Satan, and thus was heard commanding loud. +Vanguard, to right and left the front unfold; +That all may see who hate us, how we seek +Peace and composure, and with open breast +Stand ready to receive them, if they like +Our overture; and turn not back perverse: +But that I doubt; however witness, Heaven! +Heaven, witness thou anon! while we discharge +Freely our part: ye, who appointed stand +Do as you have in charge, and briefly touch +What we propound, and loud that all may hear! +So scoffing in ambiguous words, he scarce +Had ended; when to right and left the front +Divided, and to either flank retired: +Which to our eyes discovered, new and strange, +A triple mounted row of pillars laid +On wheels (for like to pillars most they seemed, +Or hollowed bodies made of oak or fir, +With branches lopt, in wood or mountain felled,) +Brass, iron, stony mould, had not their mouths +With hideous orifice gaped on us wide, +Portending hollow truce: At each behind +A Seraph stood, and in his hand a reed +Stood waving tipt with fire; while we, suspense, +Collected stood within our thoughts amused, +Not long; for sudden all at once their reeds +Put forth, and to a narrow vent applied +With nicest touch. Immediate in a flame, +But soon obscured with smoke, all Heaven appeared, +From those deep-throated engines belched, whose roar +Embowelled with outrageous noise the air, +And all her entrails tore, disgorging foul +Their devilish glut, chained thunderbolts and hail +Of iron globes; which, on the victor host +Levelled, with such impetuous fury smote, +That, whom they hit, none on their feet might stand, +Though standing else as rocks, but down they fell +By thousands, Angel on Arch-Angel rolled; +The sooner for their arms; unarmed, they might +Have easily, as Spirits, evaded swift +By quick contraction or remove; but now +Foul dissipation followed, and forced rout; +Nor served it to relax their serried files. +What should they do? if on they rushed, repulse +Repeated, and indecent overthrow +Doubled, would render them yet more despised, +And to their foes a laughter; for in view +Stood ranked of Seraphim another row, +In posture to displode their second tire +Of thunder: Back defeated to return +They worse abhorred. Satan beheld their plight, +And to his mates thus in derision called. +O Friends! why come not on these victors proud +Ere while they fierce were coming; and when we, +To entertain them fair with open front +And breast, (what could we more?) propounded terms +Of composition, straight they changed their minds, +Flew off, and into strange vagaries fell, +As they would dance; yet for a dance they seemed +Somewhat extravagant and wild; perhaps +For joy of offered peace: But I suppose, +If our proposals once again were heard, +We should compel them to a quick result. +To whom thus Belial, in like gamesome mood. +Leader! the terms we sent were terms of weight, +Of hard contents, and full of force urged home; +Such as we might perceive amused them all, +And stumbled many: Who receives them right, +Had need from head to foot well understand; +Not understood, this gift they have besides, +They show us when our foes walk not upright. +So they among themselves in pleasant vein +Stood scoffing, hightened in their thoughts beyond +All doubt of victory: Eternal Might +To match with their inventions they presumed +So easy, and of his thunder made a scorn, +And all his host derided, while they stood +A while in trouble: But they stood not long; +Rage prompted them at length, and found them arms +Against such hellish mischief fit to oppose. +Forthwith (behold the excellence, the power, +Which God hath in his mighty Angels placed!) +Their arms away they threw, and to the hills +(For Earth hath this variety from Heaven +Of pleasure situate in hill and dale,) +Light as the lightning glimpse they ran, they flew; +From their foundations loosening to and fro, +They plucked the seated hills, with all their load, +Rocks, waters, woods, and by the shaggy tops +Up-lifting bore them in their hands: Amaze, +Be sure, and terrour, seized the rebel host, +When coming towards them so dread they saw +The bottom of the mountains upward turned; +Till on those cursed engines' triple-row +They saw them whelmed, and all their confidence +Under the weight of mountains buried deep; +Themselves invaded next, and on their heads +Main promontories flung, which in the air +Came shadowing, and oppressed whole legions armed; +Their armour helped their harm, crushed in and bruised +Into their substance pent, which wrought them pain +Implacable, and many a dolorous groan; +Long struggling underneath, ere they could wind +Out of such prison, though Spirits of purest light, +Purest at first, now gross by sinning grown. +The rest, in imitation, to like arms +Betook them, and the neighbouring hills uptore: +So hills amid the air encountered hills, +Hurled to and fro with jaculation dire; +That under ground they fought in dismal shade; +Infernal noise! war seemed a civil game +To this uproar; horrid confusion heaped +Upon confusion rose: And now all Heaven +Had gone to wrack, with ruin overspread; +Had not the Almighty Father, where he sits +Shrined in his sanctuary of Heaven secure, +Consulting on the sum of things, foreseen +This tumult, and permitted all, advised: +That his great purpose he might so fulfil, +To honour his anointed Son avenged +Upon his enemies, and to declare +All power on him transferred: Whence to his Son, +The Assessour of his throne, he thus began. +Effulgence of my glory, Son beloved, +Son, in whose face invisible is beheld +Visibly, what by Deity I am; +And in whose hand what by decree I do, +Second Omnipotence! two days are past, +Two days, as we compute the days of Heaven, +Since Michael and his Powers went forth to tame +These disobedient: Sore hath been their fight, +As likeliest was, when two such foes met armed; +For to themselves I left them; and thou knowest, +Equal in their creation they were formed, +Save what sin hath impaired; which yet hath wrought +Insensibly, for I suspend their doom; +Whence in perpetual fight they needs must last +Endless, and no solution will be found: +War wearied hath performed what war can do, +And to disordered rage let loose the reins +With mountains, as with weapons, armed; which makes +Wild work in Heaven, and dangerous to the main. +Two days are therefore past, the third is thine; +For thee I have ordained it; and thus far +Have suffered, that the glory may be thine +Of ending this great war, since none but Thou +Can end it. Into thee such virtue and grace +Immense I have transfused, that all may know +In Heaven and Hell thy power above compare; +And, this perverse commotion governed thus, +To manifest thee worthiest to be Heir +Of all things; to be Heir, and to be King +By sacred unction, thy deserved right. +Go then, Thou Mightiest, in thy Father's might; +Ascend my chariot, guide the rapid wheels +That shake Heaven's basis, bring forth all my war, +My bow and thunder, my almighty arms +Gird on, and sword upon thy puissant thigh; +Pursue these sons of darkness, drive them out +From all Heaven's bounds into the utter deep: +There let them learn, as likes them, to despise +God, and Messiah his anointed King. +He said, and on his Son with rays direct +Shone full; he all his Father full expressed +Ineffably into his face received; +And thus the Filial Godhead answering spake. +O Father, O Supreme of heavenly Thrones, +First, Highest, Holiest, Best; thou always seek'st +To glorify thy Son, I always thee, +As is most just: This I my glory account, +My exaltation, and my whole delight, +That thou, in me well pleased, declarest thy will +Fulfilled, which to fulfil is all my bliss. +Scepter and power, thy giving, I assume, +And gladlier shall resign, when in the end +Thou shalt be all in all, and I in thee +For ever; and in me all whom thou lovest: +But whom thou hatest, I hate, and can put on +Thy terrours, as I put thy mildness on, +Image of thee in all things; and shall soon, +Armed with thy might, rid Heaven of these rebelled; +To their prepared ill mansion driven down, +To chains of darkness, and the undying worm; +That from thy just obedience could revolt, +Whom to obey is happiness entire. +Then shall thy Saints unmixed, and from the impure +Far separate, circling thy holy mount, +Unfeigned Halleluiahs to thee sing, +Hymns of high praise, and I among them Chief. +So said, he, o'er his scepter bowing, rose +From the right hand of Glory where he sat; +And the third sacred morn began to shine, +Dawning through Heaven. Forth rushed with whirlwind sound +The chariot of Paternal Deity, +Flashing thick flames, wheel within wheel undrawn, +Itself instinct with Spirit, but convoyed +By four Cherubick shapes; four faces each +Had wonderous; as with stars, their bodies all +And wings were set with eyes; with eyes the wheels +Of beryl, and careering fires between; +Over their heads a crystal firmament, +Whereon a sapphire throne, inlaid with pure +Amber, and colours of the showery arch. +He, in celestial panoply all armed +Of radiant Urim, work divinely wrought, +Ascended; at his right hand Victory +Sat eagle-winged; beside him hung his bow +And quiver with three-bolted thunder stored; +And from about him fierce effusion rolled +Of smoke, and bickering flame, and sparkles dire: +Attended with ten thousand thousand Saints, +He onward came; far off his coming shone; +And twenty thousand (I their number heard) +Chariots of God, half on each hand, were seen; +He on the wings of Cherub rode sublime +On the crystalline sky, in sapphire throned, +Illustrious far and wide; but by his own +First seen: Them unexpected joy surprised, +When the great ensign of Messiah blazed +Aloft by Angels borne, his sign in Heaven; +Under whose conduct Michael soon reduced +His army, circumfused on either wing, +Under their Head imbodied all in one. +Before him Power Divine his way prepared; +At his command the uprooted hills retired +Each to his place; they heard his voice, and went +Obsequious; Heaven his wonted face renewed, +And with fresh flowerets hill and valley smiled. +This saw his hapless foes, but stood obdured, +And to rebellious fight rallied their Powers, +Insensate, hope conceiving from despair. +In heavenly Spirits could such perverseness dwell? +But to convince the proud what signs avail, +Or wonders move the obdurate to relent? +They, hardened more by what might most reclaim, +Grieving to see his glory, at the sight +Took envy; and, aspiring to his highth, +Stood re-embattled fierce, by force or fraud +Weening to prosper, and at length prevail +Against God and Messiah, or to fall +In universal ruin last; and now +To final battle drew, disdaining flight, +Or faint retreat; when the great Son of God +To all his host on either hand thus spake. +Stand still in bright array, ye Saints; here stand, +Ye Angels armed; this day from battle rest: +Faithful hath been your warfare, and of God +Accepted, fearless in his righteous cause; +And as ye have received, so have ye done, +Invincibly: But of this cursed crew +The punishment to other hand belongs; +Vengeance is his, or whose he sole appoints: +Number to this day's work is not ordained, +Nor multitude; stand only, and behold +God's indignation on these godless poured +By me; not you, but me, they have despised, +Yet envied; against me is all their rage, +Because the Father, to whom in Heaven s'preme +Kingdom, and power, and glory appertains, +Hath honoured me, according to his will. +Therefore to me their doom he hath assigned; +That they may have their wish, to try with me +In battle which the stronger proves; they all, +Or I alone against them; since by strength +They measure all, of other excellence +Not emulous, nor care who them excels; +Nor other strife with them do I vouchsafe. +So spake the Son, and into terrour changed +His countenance too severe to be beheld, +And full of wrath bent on his enemies. +At once the Four spread out their starry wings +With dreadful shade contiguous, and the orbs +Of his fierce chariot rolled, as with the sound +Of torrent floods, or of a numerous host. +He on his impious foes right onward drove, +Gloomy as night; under his burning wheels +The stedfast empyrean shook throughout, +All but the throne itself of God. Full soon +Among them he arrived; in his right hand +Grasping ten thousand thunders, which he sent +Before him, such as in their souls infixed +Plagues: They, astonished, all resistance lost, +All courage; down their idle weapons dropt: +O'er shields, and helms, and helmed heads he rode +Of Thrones and mighty Seraphim prostrate, +That wished the mountains now might be again +Thrown on them, as a shelter from his ire. +Nor less on either side tempestuous fell +His arrows, from the fourfold-visaged Four +Distinct with eyes, and from the living wheels +Distinct alike with multitude of eyes; +One Spirit in them ruled; and every eye +Glared lightning, and shot forth pernicious fire +Among the accursed, that withered all their strength, +And of their wonted vigour left them drained, +Exhausted, spiritless, afflicted, fallen. +Yet half his strength he put not forth, but checked +His thunder in mid volley; for he meant +Not to destroy, but root them out of Heaven: +The overthrown he raised, and as a herd +Of goats or timorous flock together thronged +Drove them before him thunder-struck, pursued +With terrours, and with furies, to the bounds +And crystal wall of Heaven; which, opening wide, +Rolled inward, and a spacious gap disclosed +Into the wasteful deep: The monstrous sight +Struck them with horrour backward, but far worse +Urged them behind: Headlong themselves they threw +Down from the verge of Heaven; eternal wrath +Burnt after them to the bottomless pit. +Hell heard the unsufferable noise, Hell saw +Heaven ruining from Heaven, and would have fled +Affrighted; but strict Fate had cast too deep +Her dark foundations, and too fast had bound. +Nine days they fell: Confounded Chaos roared, +And felt tenfold confusion in their fall +Through his wild anarchy, so huge a rout +Incumbered him with ruin: Hell at last +Yawning received them whole, and on them closed; +Hell, their fit habitation, fraught with fire +Unquenchable, the house of woe and pain. +Disburdened Heaven rejoiced, and soon repaired +Her mural breach, returning whence it rolled. +Sole victor, from the expulsion of his foes, +Messiah his triumphal chariot turned: +To meet him all his Saints, who silent stood +Eye-witnesses of his almighty acts, +With jubilee advanced; and, as they went, +Shaded with branching palm, each Order bright, +Sung triumph, and him sung victorious King, +Son, Heir, and Lord, to him dominion given, +Worthiest to reign: He, celebrated, rode +Triumphant through mid Heaven, into the courts +And temple of his Mighty Father throned +On high; who into glory him received, +Where now he sits at the right hand of bliss. +Thus, measuring things in Heaven by things on Earth, +At thy request, and that thou mayest beware +By what is past, to thee I have revealed +What might have else to human race been hid; +The discord which befel, and war in Heaven +Among the angelick Powers, and the deep fall +Of those too high aspiring, who rebelled +With Satan; he who envies now thy state, +Who now is plotting how he may seduce +Thee also from obedience, that, with him +Bereaved of happiness, thou mayest partake +His punishment, eternal misery; +Which would be all his solace and revenge, +As a despite done against the Most High, +Thee once to gain companion of his woe. +But listen not to his temptations, warn +Thy weaker; let it profit thee to have heard, +By terrible example, the reward +Of disobedience; firm they might have stood, +Yet fell; remember, and fear to transgress. + + + +Book VII + + +Descend from Heaven, Urania, by that name +If rightly thou art called, whose voice divine +Following, above the Olympian hill I soar, +Above the flight of Pegasean wing! +The meaning, not the name, I call: for thou +Nor of the Muses nine, nor on the top +Of old Olympus dwellest; but, heavenly-born, +Before the hills appeared, or fountain flowed, +Thou with eternal Wisdom didst converse, +Wisdom thy sister, and with her didst play +In presence of the Almighty Father, pleased +With thy celestial song. Up led by thee +Into the Heaven of Heavens I have presumed, +An earthly guest, and drawn empyreal air, +Thy tempering: with like safety guided down +Return me to my native element: +Lest from this flying steed unreined, (as once +Bellerophon, though from a lower clime,) +Dismounted, on the Aleian field I fall, +Erroneous there to wander, and forlorn. +Half yet remains unsung, but narrower bound +Within the visible diurnal sphere; +Standing on earth, not rapt above the pole, +More safe I sing with mortal voice, unchanged +To hoarse or mute, though fallen on evil days, +On evil days though fallen, and evil tongues; +In darkness, and with dangers compassed round, +And solitude; yet not alone, while thou +Visitest my slumbers nightly, or when morn +Purples the east: still govern thou my song, +Urania, and fit audience find, though few. +But drive far off the barbarous dissonance +Of Bacchus and his revellers, the race +Of that wild rout that tore the Thracian bard +In Rhodope, where woods and rocks had ears +To rapture, till the savage clamour drowned +Both harp and voice; nor could the Muse defend +Her son. So fail not thou, who thee implores: +For thou art heavenly, she an empty dream. +Say, Goddess, what ensued when Raphael, +The affable Arch-Angel, had forewarned +Adam, by dire example, to beware +Apostasy, by what befel in Heaven +To those apostates; lest the like befall +In Paradise to Adam or his race, +Charged not to touch the interdicted tree, +If they transgress, and slight that sole command, +So easily obeyed amid the choice +Of all tastes else to please their appetite, +Though wandering. He, with his consorted Eve, +The story heard attentive, and was filled +With admiration and deep muse, to hear +Of things so high and strange; things, to their thought +So unimaginable, as hate in Heaven, +And war so near the peace of God in bliss, +With such confusion: but the evil, soon +Driven back, redounded as a flood on those +From whom it sprung; impossible to mix +With blessedness. Whence Adam soon repealed +The doubts that in his heart arose: and now +Led on, yet sinless, with desire to know +What nearer might concern him, how this world +Of Heaven and Earth conspicuous first began; +When, and whereof created; for what cause; +What within Eden, or without, was done +Before his memory; as one whose drouth +Yet scarce allayed still eyes the current stream, +Whose liquid murmur heard new thirst excites, +Proceeded thus to ask his heavenly guest. +Great things, and full of wonder in our ears, +Far differing from this world, thou hast revealed, +Divine interpreter! by favour sent +Down from the empyrean, to forewarn +Us timely of what might else have been our loss, +Unknown, which human knowledge could not reach; +For which to the infinitely Good we owe +Immortal thanks, and his admonishment +Receive, with solemn purpose to observe +Immutably his sovran will, the end +Of what we are. But since thou hast vouchsafed +Gently, for our instruction, to impart +Things above earthly thought, which yet concerned +Our knowing, as to highest wisdom seemed, +Deign to descend now lower, and relate +What may no less perhaps avail us known, +How first began this Heaven which we behold +Distant so high, with moving fires adorned +Innumerable; and this which yields or fills +All space, the ambient air wide interfused +Embracing round this floried Earth; what cause +Moved the Creator, in his holy rest +Through all eternity, so late to build +In Chaos; and the work begun, how soon +Absolved; if unforbid thou mayest unfold +What we, not to explore the secrets ask +Of his eternal empire, but the more +To magnify his works, the more we know. +And the great light of day yet wants to run +Much of his race though steep; suspense in Heaven, +Held by thy voice, thy potent voice, he hears, +And longer will delay to hear thee tell +His generation, and the rising birth +Of Nature from the unapparent Deep: +Or if the star of evening and the moon +Haste to thy audience, Night with her will bring, +Silence; and Sleep, listening to thee, will watch; +Or we can bid his absence, till thy song +End, and dismiss thee ere the morning shine. +Thus Adam his illustrious guest besought: +And thus the Godlike Angel answered mild. +This also thy request, with caution asked, +Obtain; though to recount almighty works +What words or tongue of Seraph can suffice, +Or heart of man suffice to comprehend? +Yet what thou canst attain, which best may serve +To glorify the Maker, and infer +Thee also happier, shall not be withheld +Thy hearing; such commission from above +I have received, to answer thy desire +Of knowledge within bounds; beyond, abstain +To ask; nor let thine own inventions hope +Things not revealed, which the invisible King, +Only Omniscient, hath suppressed in night; +To none communicable in Earth or Heaven: +Enough is left besides to search and know. +But knowledge is as food, and needs no less +Her temperance over appetite, to know +In measure what the mind may well contain; +Oppresses else with surfeit, and soon turns +Wisdom to folly, as nourishment to wind. +Know then, that, after Lucifer from Heaven +(So call him, brighter once amidst the host +Of Angels, than that star the stars among,) +Fell with his flaming legions through the deep +Into his place, and the great Son returned +Victorious with his Saints, the Omnipotent +Eternal Father from his throne beheld +Their multitude, and to his Son thus spake. +At least our envious Foe hath failed, who thought +All like himself rebellious, by whose aid +This inaccessible high strength, the seat +Of Deity supreme, us dispossessed, +He trusted to have seised, and into fraud +Drew many, whom their place knows here no more: +Yet far the greater part have kept, I see, +Their station; Heaven, yet populous, retains +Number sufficient to possess her realms +Though wide, and this high temple to frequent +With ministeries due, and solemn rites: +But, lest his heart exalt him in the harm +Already done, to have dispeopled Heaven, +My damage fondly deemed, I can repair +That detriment, if such it be to lose +Self-lost; and in a moment will create +Another world, out of one man a race +Of men innumerable, there to dwell, +Not here; till, by degrees of merit raised, +They open to themselves at length the way +Up hither, under long obedience tried; +And Earth be changed to Heaven, and Heaven to Earth, +One kingdom, joy and union without end. +Mean while inhabit lax, ye Powers of Heaven; +And thou my Word, begotten Son, by thee +This I perform; speak thou, and be it done! +My overshadowing Spirit and Might with thee +I send along; ride forth, and bid the Deep +Within appointed bounds be Heaven and Earth; +Boundless the Deep, because I Am who fill +Infinitude, nor vacuous the space. +Though I, uncircumscribed myself, retire, +And put not forth my goodness, which is free +To act or not, Necessity and Chance +Approach not me, and what I will is Fate. +So spake the Almighty, and to what he spake +His Word, the Filial Godhead, gave effect. +Immediate are the acts of God, more swift +Than time or motion, but to human ears +Cannot without process of speech be told, +So told as earthly notion can receive. +Great triumph and rejoicing was in Heaven, +When such was heard declared the Almighty's will; +Glory they sung to the Most High, good will +To future men, and in their dwellings peace; +Glory to Him, whose just avenging ire +Had driven out the ungodly from his sight +And the habitations of the just; to Him +Glory and praise, whose wisdom had ordained +Good out of evil to create; instead +Of Spirits malign, a better race to bring +Into their vacant room, and thence diffuse +His good to worlds and ages infinite. +So sang the Hierarchies: Mean while the Son +On his great expedition now appeared, +Girt with Omnipotence, with radiance crowned +Of Majesty Divine; sapience and love +Immense, and all his Father in him shone. +About his chariot numberless were poured +Cherub, and Seraph, Potentates, and Thrones, +And Virtues, winged Spirits, and chariots winged +From the armoury of God; where stand of old +Myriads, between two brazen mountains lodged +Against a solemn day, harnessed at hand, +Celestial equipage; and now came forth +Spontaneous, for within them Spirit lived, +Attendant on their Lord: Heaven opened wide +Her ever-during gates, harmonious sound +On golden hinges moving, to let forth +The King of Glory, in his powerful Word +And Spirit, coming to create new worlds. +On heavenly ground they stood; and from the shore +They viewed the vast immeasurable abyss +Outrageous as a sea, dark, wasteful, wild, +Up from the bottom turned by furious winds +And surging waves, as mountains, to assault +Heaven's highth, and with the center mix the pole. +Silence, ye troubled Waves, and thou Deep, peace, +Said then the Omnifick Word; your discord end! +Nor staid; but, on the wings of Cherubim +Uplifted, in paternal glory rode +Far into Chaos, and the world unborn; +For Chaos heard his voice: Him all his train +Followed in bright procession, to behold +Creation, and the wonders of his might. +Then staid the fervid wheels, and in his hand +He took the golden compasses, prepared +In God's eternal store, to circumscribe +This universe, and all created things: +One foot he centered, and the other turned +Round through the vast profundity obscure; +And said, Thus far extend, thus far thy bounds, +This be thy just circumference, O World! +Thus God the Heaven created, thus the Earth, +Matter unformed and void: Darkness profound +Covered the abyss: but on the watery calm +His brooding wings the Spirit of God outspread, +And vital virtue infused, and vital warmth +Throughout the fluid mass; but downward purged +The black tartareous cold infernal dregs, +Adverse to life: then founded, then conglobed +Like things to like; the rest to several place +Disparted, and between spun out the air; +And Earth self-balanced on her center hung. +Let there be light, said God; and forthwith Light +Ethereal, first of things, quintessence pure, +Sprung from the deep; and from her native east +To journey through the aery gloom began, +Sphered in a radiant cloud, for yet the sun +Was not; she in a cloudy tabernacle +Sojourned the while. God saw the light was good; +And light from darkness by the hemisphere +Divided: light the Day, and darkness Night, +He named. Thus was the first day even and morn: +Nor past uncelebrated, nor unsung +By the celestial quires, when orient light +Exhaling first from darkness they beheld; +Birth-day of Heaven and Earth; with joy and shout +The hollow universal orb they filled, +And touched their golden harps, and hymning praised +God and his works; Creator him they sung, +Both when first evening was, and when first morn. +Again, God said, Let there be firmament +Amid the waters, and let it divide +The waters from the waters; and God made +The firmament, expanse of liquid, pure, +Transparent, elemental air, diffused +In circuit to the uttermost convex +Of this great round; partition firm and sure, +The waters underneath from those above +Dividing: for as earth, so he the world +Built on circumfluous waters calm, in wide +Crystalline ocean, and the loud misrule +Of Chaos far removed; lest fierce extremes +Contiguous might distemper the whole frame: +And Heaven he named the Firmament: So even +And morning chorus sung the second day. +The Earth was formed, but in the womb as yet +Of waters, embryon immature involved, +Appeared not: over all the face of Earth +Main ocean flowed, not idle; but, with warm +Prolifick humour softening all her globe, +Fermented the great mother to conceive, +Satiate with genial moisture; when God said, +Be gathered now ye waters under Heaven +Into one place, and let dry land appear. +Immediately the mountains huge appear +Emergent, and their broad bare backs upheave +Into the clouds; their tops ascend the sky: +So high as heaved the tumid hills, so low +Down sunk a hollow bottom broad and deep, +Capacious bed of waters: Thither they +Hasted with glad precipitance, uprolled, +As drops on dust conglobing from the dry: +Part rise in crystal wall, or ridge direct, +For haste; such flight the great command impressed +On the swift floods: As armies at the call +Of trumpet (for of armies thou hast heard) +Troop to their standard; so the watery throng, +Wave rolling after wave, where way they found, +If steep, with torrent rapture, if through plain, +Soft-ebbing; nor withstood them rock or hill; +But they, or under ground, or circuit wide +With serpent errour wandering, found their way, +And on the washy oose deep channels wore; +Easy, ere God had bid the ground be dry, +All but within those banks, where rivers now +Stream, and perpetual draw their humid train. +The dry land, Earth; and the great receptacle +Of congregated waters, he called Seas: +And saw that it was good; and said, Let the Earth +Put forth the verdant grass, herb yielding seed, +And fruit-tree yielding fruit after her kind, +Whose seed is in herself upon the Earth. +He scarce had said, when the bare Earth, till then +Desart and bare, unsightly, unadorned, +Brought forth the tender grass, whose verdure clad +Her universal face with pleasant green; +Then herbs of every leaf, that sudden flowered +Opening their various colours, and made gay +Her bosom, smelling sweet: and, these scarce blown, +Forth flourished thick the clustering vine, forth crept +The swelling gourd, up stood the corny reed +Embattled in her field, and the humble shrub, +And bush with frizzled hair implicit: Last +Rose, as in dance, the stately trees, and spread +Their branches hung with copious fruit, or gemmed +Their blossoms: With high woods the hills were crowned; +With tufts the valleys, and each fountain side; +With borders long the rivers: that Earth now +Seemed like to Heaven, a seat where Gods might dwell, +Or wander with delight, and love to haunt +Her sacred shades: though God had yet not rained +Upon the Earth, and man to till the ground +None was; but from the Earth a dewy mist +Went up, and watered all the ground, and each +Plant of the field; which, ere it was in the Earth, +God made, and every herb, before it grew +On the green stem: God saw that it was good: +So even and morn recorded the third day. +Again the Almighty spake, Let there be lights +High in the expanse of Heaven, to divide +The day from night; and let them be for signs, +For seasons, and for days, and circling years; +And let them be for lights, as I ordain +Their office in the firmament of Heaven, +To give light on the Earth; and it was so. +And God made two great lights, great for their use +To Man, the greater to have rule by day, +The less by night, altern; and made the stars, +And set them in the firmament of Heaven +To illuminate the Earth, and rule the day +In their vicissitude, and rule the night, +And light from darkness to divide. God saw, +Surveying his great work, that it was good: +For of celestial bodies first the sun +A mighty sphere he framed, unlightsome first, +Though of ethereal mould: then formed the moon +Globose, and every magnitude of stars, +And sowed with stars the Heaven, thick as a field: +Of light by far the greater part he took, +Transplanted from her cloudy shrine, and placed +In the sun's orb, made porous to receive +And drink the liquid light; firm to retain +Her gathered beams, great palace now of light. +Hither, as to their fountain, other stars +Repairing, in their golden urns draw light, +And hence the morning-planet gilds her horns; +By tincture or reflection they augment +Their small peculiar, though from human sight +So far remote, with diminution seen, +First in his east the glorious lamp was seen, +Regent of day, and all the horizon round +Invested with bright rays, jocund to run +His longitude through Heaven's high road; the gray +Dawn, and the Pleiades, before him danced, +Shedding sweet influence: Less bright the moon, +But opposite in levelled west was set, +His mirrour, with full face borrowing her light +From him; for other light she needed none +In that aspect, and still that distance keeps +Till night; then in the east her turn she shines, +Revolved on Heaven's great axle, and her reign +With thousand lesser lights dividual holds, +With thousand thousand stars, that then appeared +Spangling the hemisphere: Then first adorned +With their bright luminaries that set and rose, +Glad evening and glad morn crowned the fourth day. +And God said, Let the waters generate +Reptile with spawn abundant, living soul: +And let fowl fly above the Earth, with wings +Displayed on the open firmament of Heaven. +And God created the great whales, and each +Soul living, each that crept, which plenteously +The waters generated by their kinds; +And every bird of wing after his kind; +And saw that it was good, and blessed them, saying. +Be fruitful, multiply, and in the seas, +And lakes, and running streams, the waters fill; +And let the fowl be multiplied, on the Earth. +Forthwith the sounds and seas, each creek and bay, +With fry innumerable swarm, and shoals +Of fish that with their fins, and shining scales, +Glide under the green wave, in sculls that oft +Bank the mid sea: part single, or with mate, +Graze the sea-weed their pasture, and through groves +Of coral stray; or, sporting with quick glance, +Show to the sun their waved coats dropt with gold; +Or, in their pearly shells at ease, attend +Moist nutriment; or under rocks their food +In jointed armour watch: on smooth the seal +And bended dolphins play: part huge of bulk +Wallowing unwieldy, enormous in their gait, +Tempest the ocean: there leviathan, +Hugest of living creatures, on the deep +Stretched like a promontory sleeps or swims, +And seems a moving land; and at his gills +Draws in, and at his trunk spouts out, a sea. +Mean while the tepid caves, and fens, and shores, +Their brood as numerous hatch, from the egg that soon +Bursting with kindly rupture forth disclosed +Their callow young; but feathered soon and fledge +They summed their pens; and, soaring the air sublime, +With clang despised the ground, under a cloud +In prospect; there the eagle and the stork +On cliffs and cedar tops their eyries build: +Part loosely wing the region, part more wise +In common, ranged in figure, wedge their way, +Intelligent of seasons, and set forth +Their aery caravan, high over seas +Flying, and over lands, with mutual wing +Easing their flight; so steers the prudent crane +Her annual voyage, borne on winds; the air +Floats as they pass, fanned with unnumbered plumes: +From branch to branch the smaller birds with song +Solaced the woods, and spread their painted wings +Till even; nor then the solemn nightingale +Ceased warbling, but all night tun'd her soft lays: +Others, on silver lakes and rivers, bathed +Their downy breast; the swan with arched neck, +Between her white wings mantling proudly, rows +Her state with oary feet; yet oft they quit +The dank, and, rising on stiff pennons, tower +The mid aereal sky: Others on ground +Walked firm; the crested cock whose clarion sounds +The silent hours, and the other whose gay train +Adorns him, coloured with the florid hue +Of rainbows and starry eyes. The waters thus +With fish replenished, and the air with fowl, +Evening and morn solemnized the fifth day. +The sixth, and of creation last, arose +With evening harps and matin; when God said, +Let the Earth bring forth soul living in her kind, +Cattle, and creeping things, and beast of the Earth, +Each in their kind. The Earth obeyed, and straight +Opening her fertile womb teemed at a birth +Innumerous living creatures, perfect forms, +Limbed and full grown: Out of the ground up rose, +As from his lair, the wild beast where he wons +In forest wild, in thicket, brake, or den; +Among the trees in pairs they rose, they walked: +The cattle in the fields and meadows green: +Those rare and solitary, these in flocks +Pasturing at once, and in broad herds upsprung. +The grassy clods now calved; now half appeared +The tawny lion, pawing to get free +His hinder parts, then springs as broke from bonds, +And rampant shakes his brinded mane; the ounce, +The libbard, and the tiger, as the mole +Rising, the crumbled earth above them threw +In hillocks: The swift stag from under ground +Bore up his branching head: Scarce from his mould +Behemoth biggest born of earth upheaved +His vastness: Fleeced the flocks and bleating rose, +As plants: Ambiguous between sea and land +The river-horse, and scaly crocodile. +At once came forth whatever creeps the ground, +Insect or worm: those waved their limber fans +For wings, and smallest lineaments exact +In all the liveries decked of summer's pride +With spots of gold and purple, azure and green: +These, as a line, their long dimension drew, +Streaking the ground with sinuous trace; not all +Minims of nature; some of serpent-kind, +Wonderous in length and corpulence, involved +Their snaky folds, and added wings. First crept +The parsimonious emmet, provident +Of future; in small room large heart enclosed; +Pattern of just equality perhaps +Hereafter, joined in her popular tribes +Of commonalty: Swarming next appeared +The female bee, that feeds her husband drone +Deliciously, and builds her waxen cells +With honey stored: The rest are numberless, +And thou their natures knowest, and gavest them names, +Needless to thee repeated; nor unknown +The serpent, subtlest beast of all the field, +Of huge extent sometimes, with brazen eyes +And hairy mane terrifick, though to thee +Not noxious, but obedient at thy call. +Now Heaven in all her glory shone, and rolled +Her motions, as the great first Mover's hand +First wheeled their course: Earth in her rich attire +Consummate lovely smiled; air, water, earth, +By fowl, fish, beast, was flown, was swum, was walked, +Frequent; and of the sixth day yet remained: +There wanted yet the master-work, the end +Of all yet done; a creature, who, not prone +And brute as other creatures, but endued +With sanctity of reason, might erect +His stature, and upright with front serene +Govern the rest, self-knowing; and from thence +Magnanimous to correspond with Heaven, +But grateful to acknowledge whence his good +Descends, thither with heart, and voice, and eyes +Directed in devotion, to adore +And worship God Supreme, who made him chief +Of all his works: therefore the Omnipotent +Eternal Father (for where is not he +Present?) thus to his Son audibly spake. +Let us make now Man in our image, Man +In our similitude, and let them rule +Over the fish and fowl of sea and air, +Beast of the field, and over all the Earth, +And every creeping thing that creeps the ground. +This said, he formed thee, Adam, thee, O Man, +Dust of the ground, and in thy nostrils breathed +The breath of life; in his own image he +Created thee, in the image of God +Express; and thou becamest a living soul. +Male he created thee; but thy consort +Female, for race; then blessed mankind, and said, +Be fruitful, multiply, and fill the Earth; +Subdue it, and throughout dominion hold +Over fish of the sea, and fowl of the air, +And every living thing that moves on the Earth. +Wherever thus created, for no place +Is yet distinct by name, thence, as thou knowest, +He brought thee into this delicious grove, +This garden, planted with the trees of God, +Delectable both to behold and taste; +And freely all their pleasant fruit for food +Gave thee; all sorts are here that all the Earth yields, +Variety without end; but of the tree, +Which, tasted, works knowledge of good and evil, +Thou mayest not; in the day thou eatest, thou diest; +Death is the penalty imposed; beware, +And govern well thy appetite; lest Sin +Surprise thee, and her black attendant Death. +Here finished he, and all that he had made +Viewed, and behold all was entirely good; +So even and morn accomplished the sixth day: +Yet not till the Creator from his work +Desisting, though unwearied, up returned, +Up to the Heaven of Heavens, his high abode; +Thence to behold this new created world, +The addition of his empire, how it showed +In prospect from his throne, how good, how fair, +Answering his great idea. Up he rode +Followed with acclamation, and the sound +Symphonious of ten thousand harps, that tuned +Angelick harmonies: The earth, the air +Resounded, (thou rememberest, for thou heardst,) +The heavens and all the constellations rung, +The planets in their station listening stood, +While the bright pomp ascended jubilant. +Open, ye everlasting gates! they sung, +Open, ye Heavens! your living doors;let in +The great Creator from his work returned +Magnificent, his six days work, a World; +Open, and henceforth oft; for God will deign +To visit oft the dwellings of just men, +Delighted; and with frequent intercourse +Thither will send his winged messengers +On errands of supernal grace. So sung +The glorious train ascending: He through Heaven, +That opened wide her blazing portals, led +To God's eternal house direct the way; +A broad and ample road, whose dust is gold +And pavement stars, as stars to thee appear, +Seen in the galaxy, that milky way, +Which nightly, as a circling zone, thou seest +Powdered with stars. And now on Earth the seventh +Evening arose in Eden, for the sun +Was set, and twilight from the east came on, +Forerunning night; when at the holy mount +Of Heaven's high-seated top, the imperial throne +Of Godhead, fixed for ever firm and sure, +The Filial Power arrived, and sat him down +With his great Father; for he also went +Invisible, yet staid, (such privilege +Hath Omnipresence) and the work ordained, +Author and End of all things; and, from work +Now resting, blessed and hallowed the seventh day, +As resting on that day from all his work, +But not in silence holy kept: the harp +Had work and rested not; the solemn pipe, +And dulcimer, all organs of sweet stop, +All sounds on fret by string or golden wire, +Tempered soft tunings, intermixed with voice +Choral or unison: of incense clouds, +Fuming from golden censers, hid the mount. +Creation and the six days acts they sung: +Great are thy works, Jehovah! infinite +Thy power! what thought can measure thee, or tongue +Relate thee! Greater now in thy return +Than from the giant Angels: Thee that day +Thy thunders magnified; but to create +Is greater than created to destroy. +Who can impair thee, Mighty King, or bound +Thy empire! Easily the proud attempt +Of Spirits apostate, and their counsels vain, +Thou hast repelled; while impiously they thought +Thee to diminish, and from thee withdraw +The number of thy worshippers. Who seeks +To lessen thee, against his purpose serves +To manifest the more thy might: his evil +Thou usest, and from thence createst more good. +Witness this new-made world, another Heaven +From Heaven-gate not far, founded in view +On the clear hyaline, the glassy sea; +Of amplitude almost immense, with stars +Numerous, and every star perhaps a world +Of destined habitation; but thou knowest +Their seasons: among these the seat of Men, +Earth, with her nether ocean circumfused, +Their pleasant dwelling-place. Thrice happy Men, +And sons of Men, whom God hath thus advanced! +Created in his image, there to dwell +And worship him; and in reward to rule +Over his works, on earth, in sea, or air, +And multiply a race of worshippers +Holy and just: Thrice happy, if they know +Their happiness, and persevere upright! +So sung they, and the empyrean rung +With halleluiahs: Thus was sabbath kept. +And thy request think now fulfilled, that asked +How first this world and face of things began, +And what before thy memory was done +From the beginning; that posterity, +Informed by thee, might know: If else thou seekest +Aught, not surpassing human measure, say. + + + +Book VIII + + +The Angel ended, and in Adam's ear +So charming left his voice, that he a while +Thought him still speaking, still stood fixed to hear; +Then, as new waked, thus gratefully replied. +What thanks sufficient, or what recompence +Equal, have I to render thee, divine +Historian, who thus largely hast allayed +The thirst I had of knowledge, and vouchsafed +This friendly condescension to relate +Things, else by me unsearchable; now heard +With wonder, but delight, and, as is due, +With glory attributed to the high +Creator! Something yet of doubt remains, +Which only thy solution can resolve. +When I behold this goodly frame, this world, +Of Heaven and Earth consisting; and compute +Their magnitudes; this Earth, a spot, a grain, +An atom, with the firmament compared +And all her numbered stars, that seem to roll +Spaces incomprehensible, (for such +Their distance argues, and their swift return +Diurnal,) merely to officiate light +Round this opacous Earth, this punctual spot, +One day and night; in all her vast survey +Useless besides; reasoning I oft admire, +How Nature wise and frugal could commit +Such disproportions, with superfluous hand +So many nobler bodies to create, +Greater so manifold, to this one use, +For aught appears, and on their orbs impose +Such restless revolution day by day +Repeated; while the sedentary Earth, +That better might with far less compass move, +Served by more noble than herself, attains +Her end without least motion, and receives, +As tribute, such a sumless journey brought +Of incorporeal speed, her warmth and light; +Speed, to describe whose swiftness number fails. +So spake our sire, and by his countenance seemed +Entering on studious thoughts abstruse; which Eve +Perceiving, where she sat retired in sight, +With lowliness majestick from her seat, +And grace that won who saw to wish her stay, +Rose, and went forth among her fruits and flowers, +To visit how they prospered, bud and bloom, +Her nursery; they at her coming sprung, +And, touched by her fair tendance, gladlier grew. +Yet went she not, as not with such discourse +Delighted, or not capable her ear +Of what was high: such pleasure she reserved, +Adam relating, she sole auditress; +Her husband the relater she preferred +Before the Angel, and of him to ask +Chose rather; he, she knew, would intermix +Grateful digressions, and solve high dispute +With conjugal caresses: from his lip +Not words alone pleased her. O! when meet now +Such pairs, in love and mutual honour joined? +With Goddess-like demeanour forth she went, +Not unattended; for on her, as Queen, +A pomp of winning Graces waited still, +And from about her shot darts of desire +Into all eyes, to wish her still in sight. +And Raphael now, to Adam's doubt proposed, +Benevolent and facile thus replied. +To ask or search, I blame thee not; for Heaven +Is as the book of God before thee set, +Wherein to read his wonderous works, and learn +His seasons, hours, or days, or months, or years: +This to attain, whether Heaven move or Earth, +Imports not, if thou reckon right; the rest +From Man or Angel the great Architect +Did wisely to conceal, and not divulge +His secrets to be scanned by them who ought +Rather admire; or, if they list to try +Conjecture, he his fabrick of the Heavens +Hath left to their disputes, perhaps to move +His laughter at their quaint opinions wide +Hereafter; when they come to model Heaven +And calculate the stars, how they will wield +The mighty frame; how build, unbuild, contrive +To save appearances; how gird the sphere +With centrick and eccentrick scribbled o'er, +Cycle and epicycle, orb in orb: +Already by thy reasoning this I guess, +Who art to lead thy offspring, and supposest +That bodies bright and greater should not serve +The less not bright, nor Heaven such journeys run, +Earth sitting still, when she alone receives +The benefit: Consider first, that great +Or bright infers not excellence: the Earth +Though, in comparison of Heaven, so small, +Nor glistering, may of solid good contain +More plenty than the sun that barren shines; +Whose virtue on itself works no effect, +But in the fruitful Earth; there first received, +His beams, unactive else, their vigour find. +Yet not to Earth are those bright luminaries +Officious; but to thee, Earth's habitant. +And for the Heaven's wide circuit, let it speak +The Maker's high magnificence, who built +So spacious, and his line stretched out so far; +That Man may know he dwells not in his own; +An edifice too large for him to fill, +Lodged in a small partition; and the rest +Ordained for uses to his Lord best known. +The swiftness of those circles attribute, +Though numberless, to his Omnipotence, +That to corporeal substances could add +Speed almost spiritual: Me thou thinkest not slow, +Who since the morning-hour set out from Heaven +Where God resides, and ere mid-day arrived +In Eden; distance inexpressible +By numbers that have name. But this I urge, +Admitting motion in the Heavens, to show +Invalid that which thee to doubt it moved; +Not that I so affirm, though so it seem +To thee who hast thy dwelling here on Earth. +God, to remove his ways from human sense, +Placed Heaven from Earth so far, that earthly sight, +If it presume, might err in things too high, +And no advantage gain. What if the sun +Be center to the world; and other stars, +By his attractive virtue and their own +Incited, dance about him various rounds? +Their wandering course now high, now low, then hid, +Progressive, retrograde, or standing still, +In six thou seest; and what if seventh to these +The planet earth, so stedfast though she seem, +Insensibly three different motions move? +Which else to several spheres thou must ascribe, +Moved contrary with thwart obliquities; +Or save the sun his labour, and that swift +Nocturnal and diurnal rhomb supposed, +Invisible else above all stars, the wheel +Of day and night; which needs not thy belief, +If earth, industrious of herself, fetch day +Travelling east, and with her part averse +From the sun's beam meet night, her other part +Still luminous by his ray. What if that light, +Sent from her through the wide transpicuous air, +To the terrestrial moon be as a star, +Enlightening her by day, as she by night +This earth? reciprocal, if land be there, +Fields and inhabitants: Her spots thou seest +As clouds, and clouds may rain, and rain produce +Fruits in her softened soil for some to eat +Allotted there; and other suns perhaps, +With their attendant moons, thou wilt descry, +Communicating male and female light; +Which two great sexes animate the world, +Stored in each orb perhaps with some that live. +For such vast room in Nature unpossessed +By living soul, desart and desolate, +Only to shine, yet scarce to contribute +Each orb a glimpse of light, conveyed so far +Down to this habitable, which returns +Light back to them, is obvious to dispute. +But whether thus these things, or whether not; +But whether the sun, predominant in Heaven, +Rise on the earth; or earth rise on the sun; +He from the east his flaming road begin; +Or she from west her silent course advance, +With inoffensive pace that spinning sleeps +On her soft axle, while she paces even, +And bears thee soft with the smooth hair along; +Sollicit not thy thoughts with matters hid; +Leave them to God above; him serve, and fear! +Of other creatures, as him pleases best, +Wherever placed, let him dispose; joy thou +In what he gives to thee, this Paradise +And thy fair Eve; Heaven is for thee too high +To know what passes there; be lowly wise: +Think only what concerns thee, and thy being; +Dream not of other worlds, what creatures there +Live, in what state, condition, or degree; +Contented that thus far hath been revealed +Not of Earth only, but of highest Heaven. +To whom thus Adam, cleared of doubt, replied. +How fully hast thou satisfied me, pure +Intelligence of Heaven, Angel serene! +And, freed from intricacies, taught to live +The easiest way; nor with perplexing thoughts +To interrupt the sweet of life, from which +God hath bid dwell far off all anxious cares, +And not molest us; unless we ourselves +Seek them with wandering thoughts, and notions vain. +But apt the mind or fancy is to rove +Unchecked, and of her roving is no end; +Till warned, or by experience taught, she learn, +That, not to know at large of things remote +From use, obscure and subtle; but, to know +That which before us lies in daily life, +Is the prime wisdom: What is more, is fume, +Or emptiness, or fond impertinence: +And renders us, in things that most concern, +Unpractised, unprepared, and still to seek. +Therefore from this high pitch let us descend +A lower flight, and speak of things at hand +Useful; whence, haply, mention may arise +Of something not unseasonable to ask, +By sufferance, and thy wonted favour, deigned. +Thee I have heard relating what was done +Ere my remembrance: now, hear me relate +My story, which perhaps thou hast not heard; +And day is not yet spent; till then thou seest +How subtly to detain thee I devise; +Inviting thee to hear while I relate; +Fond! were it not in hope of thy reply: +For, while I sit with thee, I seem in Heaven; +And sweeter thy discourse is to my ear +Than fruits of palm-tree pleasantest to thirst +And hunger both, from labour, at the hour +Of sweet repast; they satiate, and soon fill, +Though pleasant; but thy words, with grace divine +Imbued, bring to their sweetness no satiety. +To whom thus Raphael answered heavenly meek. +Nor are thy lips ungraceful, Sire of men, +Nor tongue ineloquent; for God on thee +Abundantly his gifts hath also poured +Inward and outward both, his image fair: +Speaking, or mute, all comeliness and grace +Attends thee; and each word, each motion, forms; +Nor less think we in Heaven of thee on Earth +Than of our fellow-servant, and inquire +Gladly into the ways of God with Man: +For God, we see, hath honoured thee, and set +On Man his equal love: Say therefore on; +For I that day was absent, as befel, +Bound on a voyage uncouth and obscure, +Far on excursion toward the gates of Hell; +Squared in full legion (such command we had) +To see that none thence issued forth a spy, +Or enemy, while God was in his work; +Lest he, incensed at such eruption bold, +Destruction with creation might have mixed. +Not that they durst without his leave attempt; +But us he sends upon his high behests +For state, as Sovran King; and to inure +Our prompt obedience. Fast we found, fast shut, +The dismal gates, and barricadoed strong; +But long ere our approaching heard within +Noise, other than the sound of dance or song, +Torment, and loud lament, and furious rage. +Glad we returned up to the coasts of light +Ere sabbath-evening: so we had in charge. +But thy relation now; for I attend, +Pleased with thy words no less than thou with mine. +So spake the Godlike Power, and thus our Sire. +For Man to tell how human life began +Is hard; for who himself beginning knew +Desire with thee still longer to converse +Induced me. As new waked from soundest sleep, +Soft on the flowery herb I found me laid, +In balmy sweat; which with his beams the sun +Soon dried, and on the reeking moisture fed. +Straight toward Heaven my wondering eyes I turned, +And gazed a while the ample sky; till, raised +By quick instinctive motion, up I sprung, +As thitherward endeavouring, and upright +Stood on my feet: about me round I saw +Hill, dale, and shady woods, and sunny plains, +And liquid lapse of murmuring streams; by these, +Creatures that lived and moved, and walked, or flew; +Birds on the branches warbling; all things smiled; +With fragrance and with joy my heart o'erflowed. +Myself I then perused, and limb by limb +Surveyed, and sometimes went, and sometimes ran +With supple joints, as lively vigour led: +But who I was, or where, or from what cause, +Knew not; to speak I tried, and forthwith spake; +My tongue obeyed, and readily could name +Whate'er I saw. Thou Sun, said I, fair light, +And thou enlightened Earth, so fresh and gay, +Ye Hills, and Dales, ye Rivers, Woods, and Plains, +And ye that live and move, fair Creatures, tell, +Tell, if ye saw, how I came thus, how here?-- +Not of myself;--by some great Maker then, +In goodness and in power pre-eminent: +Tell me, how may I know him, how adore, +From whom I have that thus I move and live, +And feel that I am happier than I know.-- +While thus I called, and strayed I knew not whither, +From where I first drew air, and first beheld +This happy light; when, answer none returned, +On a green shady bank, profuse of flowers, +Pensive I sat me down: There gentle sleep +First found me, and with soft oppression seised +My droused sense, untroubled, though I thought +I then was passing to my former state +Insensible, and forthwith to dissolve: +When suddenly stood at my head a dream, +Whose inward apparition gently moved +My fancy to believe I yet had being, +And lived: One came, methought, of shape divine, +And said, 'Thy mansion wants thee, Adam; rise, +'First Man, of men innumerable ordained +'First Father! called by thee, I come thy guide +'To the garden of bliss, thy seat prepared.' +So saying, by the hand he took me raised, +And over fields and waters, as in air +Smooth-sliding without step, last led me up +A woody mountain; whose high top was plain, +A circuit wide, enclosed, with goodliest trees +Planted, with walks, and bowers; that what I saw +Of Earth before scarce pleasant seemed. Each tree, +Loaden with fairest fruit that hung to the eye +Tempting, stirred in me sudden appetite +To pluck and eat; whereat I waked, and found +Before mine eyes all real, as the dream +Had lively shadowed: Here had new begun +My wandering, had not he, who was my guide +Up hither, from among the trees appeared, +Presence Divine. Rejoicing, but with awe, +In adoration at his feet I fell +Submiss: He reared me, and 'Whom thou soughtest I am,' +Said mildly, 'Author of all this thou seest +'Above, or round about thee, or beneath. +'This Paradise I give thee, count it thine +'To till and keep, and of the fruit to eat: +'Of every tree that in the garden grows +'Eat freely with glad heart; fear here no dearth: +'But of the tree whose operation brings +'Knowledge of good and ill, which I have set +'The pledge of thy obedience and thy faith, +'Amid the garden by the tree of life, +'Remember what I warn thee, shun to taste, +'And shun the bitter consequence: for know, +'The day thou eatest thereof, my sole command +'Transgressed, inevitably thou shalt die, +'From that day mortal; and this happy state +'Shalt lose, expelled from hence into a world +'Of woe and sorrow.' Sternly he pronounced +The rigid interdiction, which resounds +Yet dreadful in mine ear, though in my choice +Not to incur; but soon his clear aspect +Returned, and gracious purpose thus renewed. +'Not only these fair bounds, but all the Earth +'To thee and to thy race I give; as lords +'Possess it, and all things that therein live, +'Or live in sea, or air; beast, fish, and fowl. +'In sign whereof, each bird and beast behold +'After their kinds; I bring them to receive +'From thee their names, and pay thee fealty +'With low subjection; understand the same +'Of fish within their watery residence, +'Not hither summoned, since they cannot change +'Their element, to draw the thinner air.' +As thus he spake, each bird and beast behold +Approaching two and two; these cowering low +With blandishment; each bird stooped on his wing. +I named them, as they passed, and understood +Their nature, with such knowledge God endued +My sudden apprehension: But in these +I found not what methought I wanted still; +And to the heavenly Vision thus presumed. +O, by what name, for thou above all these, +Above mankind, or aught than mankind higher, +Surpassest far my naming; how may I +Adore thee, Author of this universe, +And all this good to man? for whose well being +So amply, and with hands so liberal, +Thou hast provided all things: But with me +I see not who partakes. In solitude +What happiness, who can enjoy alone, +Or, all enjoying, what contentment find? +Thus I presumptuous; and the Vision bright, +As with a smile more brightened, thus replied. +What callest thou solitude? Is not the Earth +With various living creatures, and the air +Replenished, and all these at thy command +To come and play before thee? Knowest thou not +Their language and their ways? They also know, +And reason not contemptibly: With these +Find pastime, and bear rule; thy realm is large. +So spake the Universal Lord, and seemed +So ordering: I, with leave of speech implored, +And humble deprecation, thus replied. +Let not my words offend thee, Heavenly Power; +My Maker, be propitious while I speak. +Hast thou not made me here thy substitute, +And these inferiour far beneath me set? +Among unequals what society +Can sort, what harmony, or true delight? +Which must be mutual, in proportion due +Given and received; but, in disparity +The one intense, the other still remiss, +Cannot well suit with either, but soon prove +Tedious alike: Of fellowship I speak +Such as I seek, fit to participate +All rational delight: wherein the brute +Cannot be human consort: They rejoice +Each with their kind, lion with lioness; +So fitly them in pairs thou hast combined: +Much less can bird with beast, or fish with fowl +So well converse, nor with the ox the ape; +Worse then can man with beast, and least of all. +Whereto the Almighty answered, not displeased. +A nice and subtle happiness, I see, +Thou to thyself proposest, in the choice +Of thy associates, Adam! and wilt taste +No pleasure, though in pleasure, solitary. +What thinkest thou then of me, and this my state? +Seem I to thee sufficiently possessed +Of happiness, or not? who am alone +From all eternity; for none I know +Second to me or like, equal much less. +How have I then with whom to hold converse, +Save with the creatures which I made, and those +To me inferiour, infinite descents +Beneath what other creatures are to thee? +He ceased; I lowly answered. To attain +The highth and depth of thy eternal ways +All human thoughts come short, Supreme of things! +Thou in thyself art perfect, and in thee +Is no deficience found: Not so is Man, +But in degree; the cause of his desire +By conversation with his like to help +Or solace his defects. No need that thou +Shouldst propagate, already Infinite; +And through all numbers absolute, though One: +But Man by number is to manifest +His single imperfection, and beget +Like of his like, his image multiplied, +In unity defective; which requires +Collateral love, and dearest amity. +Thou in thy secresy although alone, +Best with thyself accompanied, seekest not +Social communication; yet, so pleased, +Canst raise thy creature to what highth thou wilt +Of union or communion, deified: +I, by conversing, cannot these erect +From prone; nor in their ways complacence find. +Thus I emboldened spake, and freedom used +Permissive, and acceptance found; which gained +This answer from the gracious Voice Divine. +Thus far to try thee, Adam, I was pleased; +And find thee knowing, not of beasts alone, +Which thou hast rightly named, but of thyself; +Expressing well the spirit within thee free, +My image, not imparted to the brute; +Whose fellowship therefore unmeet for thee +Good reason was thou freely shouldst dislike; +And be so minded still: I, ere thou spakest, +Knew it not good for Man to be alone; +And no such company as then thou sawest +Intended thee; for trial only brought, +To see how thou couldest judge of fit and meet: +What next I bring shall please thee, be assured, +Thy likeness, thy fit help, thy other self, +Thy wish exactly to thy heart's desire. +He ended, or I heard no more; for now +My earthly by his heavenly overpowered, +Which it had long stood under, strained to the highth +In that celestial colloquy sublime, +As with an object that excels the sense +Dazzled and spent, sunk down; and sought repair +Of sleep, which instantly fell on me, called +By Nature as in aid, and closed mine eyes. +Mine eyes he closed, but open left the cell +Of fancy, my internal sight; by which, +Abstract as in a trance, methought I saw, +Though sleeping, where I lay, and saw the shape +Still glorious before whom awake I stood: +Who stooping opened my left side, and took +From thence a rib, with cordial spirits warm, +And life-blood streaming fresh; wide was the wound, +But suddenly with flesh filled up and healed: +The rib he formed and fashioned with his hands; +Under his forming hands a creature grew, +Man-like, but different sex; so lovely fair, +That what seemed fair in all the world, seemed now +Mean, or in her summed up, in her contained +And in her looks; which from that time infused +Sweetness into my heart, unfelt before, +And into all things from her air inspired +The spirit of love and amorous delight. +She disappeared, and left me dark; I waked +To find her, or for ever to deplore +Her loss, and other pleasures all abjure: +When out of hope, behold her, not far off, +Such as I saw her in my dream, adorned +With what all Earth or Heaven could bestow +To make her amiable: On she came, +Led by her heavenly Maker, though unseen, +And guided by his voice; nor uninformed +Of nuptial sanctity, and marriage rites: +Grace was in all her steps, Heaven in her eye, +In every gesture dignity and love. +I, overjoyed, could not forbear aloud. +This turn hath made amends; thou hast fulfilled +Thy words, Creator bounteous and benign, +Giver of all things fair! but fairest this +Of all thy gifts! nor enviest. I now see +Bone of my bone, flesh of my flesh, myself +Before me: Woman is her name;of Man +Extracted: for this cause he shall forego +Father and mother, and to his wife adhere; +And they shall be one flesh, one heart, one soul. +She heard me thus; and though divinely brought, +Yet innocence, and virgin modesty, +Her virtue, and the conscience of her worth, +That would be wooed, and not unsought be won, +Not obvious, not obtrusive, but, retired, +The more desirable; or, to say all, +Nature herself, though pure of sinful thought, +Wrought in her so, that, seeing me, she turned: +I followed her; she what was honour knew, +And with obsequious majesty approved +My pleaded reason. To the nuptial bower +I led her blushing like the morn: All Heaven, +And happy constellations, on that hour +Shed their selectest influence; the Earth +Gave sign of gratulation, and each hill; +Joyous the birds; fresh gales and gentle airs +Whispered it to the woods, and from their wings +Flung rose, flung odours from the spicy shrub, +Disporting, till the amorous bird of night +Sung spousal, and bid haste the evening-star +On his hill top, to light the bridal lamp. +Thus have I told thee all my state, and brought +My story to the sum of earthly bliss, +Which I enjoy; and must confess to find +In all things else delight indeed, but such +As, used or not, works in the mind no change, +Nor vehement desire; these delicacies +I mean of taste, sight, smell, herbs, fruits, and flowers, +Walks, and the melody of birds: but here +Far otherwise, transported I behold, +Transported touch; here passion first I felt, +Commotion strange! in all enjoyments else +Superiour and unmoved; here only weak +Against the charm of Beauty's powerful glance. +Or Nature failed in me, and left some part +Not proof enough such object to sustain; +Or, from my side subducting, took perhaps +More than enough; at least on her bestowed +Too much of ornament, in outward show +Elaborate, of inward less exact. +For well I understand in the prime end +Of Nature her the inferiour, in the mind +And inward faculties, which most excel; +In outward also her resembling less +His image who made both, and less expressing +The character of that dominion given +O'er other creatures: Yet when I approach +Her loveliness, so absolute she seems +And in herself complete, so well to know +Her own, that what she wills to do or say, +Seems wisest, virtuousest, discreetest, best: +All higher knowledge in her presence falls +Degraded; Wisdom in discourse with her +Loses discountenanced, and like Folly shows; +Authority and Reason on her wait, +As one intended first, not after made +Occasionally; and, to consummate all, +Greatness of mind and Nobleness their seat +Build in her loveliest, and create an awe +About her, as a guard angelick placed. +To whom the Angel with contracted brow. +Accuse not Nature, she hath done her part; +Do thou but thine; and be not diffident +Of Wisdom; she deserts thee not, if thou +Dismiss not her, when most thou needest her nigh, +By attributing overmuch to things +Less excellent, as thou thyself perceivest. +For, what admirest thou, what transports thee so, +An outside? fair, no doubt, and worthy well +Thy cherishing, thy honouring, and thy love; +Not thy subjection: Weigh with her thyself; +Then value: Oft-times nothing profits more +Than self-esteem, grounded on just and right +Well managed; of that skill the more thou knowest, +The more she will acknowledge thee her head, +And to realities yield all her shows: +Made so adorn for thy delight the more, +So awful, that with honour thou mayest love +Thy mate, who sees when thou art seen least wise. +But if the sense of touch, whereby mankind +Is propagated, seem such dear delight +Beyond all other; think the same vouchsafed +To cattle and each beast; which would not be +To them made common and divulged, if aught +Therein enjoyed were worthy to subdue +The soul of man, or passion in him move. +What higher in her society thou findest +Attractive, human, rational, love still; +In loving thou dost well, in passion not, +Wherein true love consists not: Love refines +The thoughts, and heart enlarges; hath his seat +In reason, and is judicious; is the scale +By which to heavenly love thou mayest ascend, +Not sunk in carnal pleasure; for which cause, +Among the beasts no mate for thee was found. +To whom thus, half abashed, Adam replied. +Neither her outside formed so fair, nor aught +In procreation common to all kinds, +(Though higher of the genial bed by far, +And with mysterious reverence I deem,) +So much delights me, as those graceful acts, +Those thousand decencies, that daily flow +From all her words and actions mixed with love +And sweet compliance, which declare unfeigned +Union of mind, or in us both one soul; +Harmony to behold in wedded pair +More grateful than harmonious sound to the ear. +Yet these subject not; I to thee disclose +What inward thence I feel, not therefore foiled, +Who meet with various objects, from the sense +Variously representing; yet, still free, +Approve the best, and follow what I approve. +To love, thou blamest me not; for Love, thou sayest, +Leads up to Heaven, is both the way and guide; +Bear with me then, if lawful what I ask: +Love not the heavenly Spirits, and how their love +Express they? by looks only? or do they mix +Irradiance, virtual or immediate touch? +To whom the Angel, with a smile that glowed +Celestial rosy red, Love's proper hue, +Answered. Let it suffice thee that thou knowest +Us happy, and without love no happiness. +Whatever pure thou in the body enjoyest, +(And pure thou wert created) we enjoy +In eminence; and obstacle find none +Of membrane, joint, or limb, exclusive bars; +Easier than air with air, if Spirits embrace, +Total they mix, union of pure with pure +Desiring, nor restrained conveyance need, +As flesh to mix with flesh, or soul with soul. +But I can now no more; the parting sun +Beyond the Earth's green Cape and verdant Isles +Hesperian sets, my signal to depart. +Be strong, live happy, and love! But, first of all, +Him, whom to love is to obey, and keep +His great command; take heed lest passion sway +Thy judgement to do aught, which else free will +Would not admit: thine, and of all thy sons, +The weal or woe in thee is placed; beware! +I in thy persevering shall rejoice, +And all the Blest: Stand fast;to stand or fall +Free in thine own arbitrement it lies. +Perfect within, no outward aid require; +And all temptation to transgress repel. +So saying, he arose; whom Adam thus +Followed with benediction. Since to part, +Go, heavenly guest, ethereal Messenger, +Sent from whose sovran goodness I adore! +Gentle to me and affable hath been +Thy condescension, and shall be honoured ever +With grateful memory: Thou to mankind +Be good and friendly still, and oft return! +So parted they; the Angel up to Heaven +From the thick shade, and Adam to his bower. + + + +Book IX + + +No more of talk where God or Angel guest +With Man, as with his friend, familiar us'd, +To sit indulgent, and with him partake +Rural repast; permitting him the while +Venial discourse unblam'd. I now must change +Those notes to tragick; foul distrust, and breach +Disloyal on the part of Man, revolt, +And disobedience: on the part of Heaven +Now alienated, distance and distaste, +Anger and just rebuke, and judgement given, +That brought into this world a world of woe, +Sin and her shadow Death, and Misery +Death's harbinger: Sad talk!yet argument +Not less but more heroick than the wrath +Of stern Achilles on his foe pursued +Thrice fugitive about Troy wall; or rage +Of Turnus for Lavinia disespous'd; +Or Neptune's ire, or Juno's, that so long +Perplexed the Greek, and Cytherea's son: + + 00482129 +If answerable style I can obtain +Of my celestial patroness, who deigns +Her nightly visitation unimplor'd, +And dictates to me slumbering; or inspires +Easy my unpremeditated verse: +Since first this subject for heroick song +Pleas'd me long choosing, and beginning late; +Not sedulous by nature to indite +Wars, hitherto the only argument +Heroick deem'd chief mastery to dissect +With long and tedious havock fabled knights +In battles feign'd; the better fortitude +Of patience and heroick martyrdom +Unsung; or to describe races and games, +Or tilting furniture, imblazon'd shields, +Impresses quaint, caparisons and steeds, +Bases and tinsel trappings, gorgeous knights +At joust and tournament; then marshall'd feast +Serv'd up in hall with sewers and seneshals; +The skill of artifice or office mean, +Not that which justly gives heroick name +To person, or to poem. Me, of these +Nor skill'd nor studious, higher argument +Remains; sufficient of itself to raise +That name, unless an age too late, or cold +Climate, or years, damp my intended wing +Depress'd; and much they may, if all be mine, +Not hers, who brings it nightly to my ear. +The sun was sunk, and after him the star +Of Hesperus, whose office is to bring +Twilight upon the earth, short arbiter +"twixt day and night, and now from end to end +Night's hemisphere had veil'd the horizon round: +When satan, who late fled before the threats +Of Gabriel out of Eden, now improv'd +In meditated fraud and malice, bent +On Man's destruction, maugre what might hap +Of heavier on himself, fearless returned +From compassing the earth; cautious of day, +Since Uriel, regent of the sun, descried +His entrance, and foreworned the Cherubim +That kept their watch; thence full of anguish driven, +The space of seven continued nights he rode +With darkness; thrice the equinoctial line +He circled; four times crossed the car of night +From pole to pole, traversing each colure; +On the eighth returned; and, on the coast averse +From entrance or Cherubick watch, by stealth +Found unsuspected way. There was a place, +Now not, though sin, not time, first wrought the change, +Where Tigris, at the foot of Paradise, +Into a gulf shot under ground, till part +Rose up a fountain by the tree of life: +In with the river sunk, and with it rose +Satan, involved in rising mist; then sought +Where to lie hid; sea he had searched, and land, +From Eden over Pontus and the pool +Maeotis, up beyond the river Ob; +Downward as far antarctick; and in length, +West from Orontes to the ocean barred +At Darien ; thence to the land where flows +Ganges and Indus: Thus the orb he roamed +With narrow search; and with inspection deep +Considered every creature, which of all +Most opportune might serve his wiles; and found +The Serpent subtlest beast of all the field. +Him after long debate, irresolute +Of thoughts revolved, his final sentence chose +Fit vessel, fittest imp of fraud, in whom +To enter, and his dark suggestions hide +From sharpest sight: for, in the wily snake +Whatever sleights, none would suspicious mark, +As from his wit and native subtlety +Proceeding; which, in other beasts observed, +Doubt might beget of diabolick power +Active within, beyond the sense of brute. +Thus he resolved, but first from inward grief +His bursting passion into plaints thus poured. +More justly, seat worthier of Gods, as built +With second thoughts, reforming what was old! +O Earth, how like to Heaven, if not preferred +For what God, after better, worse would build? +Terrestrial Heaven, danced round by other Heavens +That shine, yet bear their bright officious lamps, +Light above light, for thee alone, as seems, +In thee concentring all their precious beams +Of sacred influence! As God in Heaven +Is center, yet extends to all; so thou, +Centring, receivest from all those orbs: in thee, +Not in themselves, all their known virtue appears +Productive in herb, plant, and nobler birth +Of creatures animate with gradual life +Of growth, sense, reason, all summed up in Man. +With what delight could I have walked thee round, +If I could joy in aught, sweet interchange +Of hill, and valley, rivers, woods, and plains, +Now land, now sea and shores with forest crowned, +Rocks, dens, and caves! But I in none of these +Find place or refuge; and the more I see +Pleasures about me, so much more I feel +Torment within me, as from the hateful siege +Of contraries: all good to me becomes +Bane, and in Heaven much worse would be my state. +But neither here seek I, no nor in Heaven +To dwell, unless by mastering Heaven's Supreme; +Nor hope to be myself less miserable +By what I seek, but others to make such +As I, though thereby worse to me redound: +For only in destroying I find ease +To my relentless thoughts; and, him destroyed, +Or won to what may work his utter loss, +For whom all this was made, all this will soon +Follow, as to him linked in weal or woe; +In woe then; that destruction wide may range: +To me shall be the glory sole among +The infernal Powers, in one day to have marred +What he, Almighty styled, six nights and days +Continued making; and who knows how long +Before had been contriving? though perhaps +Not longer than since I, in one night, freed +From servitude inglorious well nigh half +The angelick name, and thinner left the throng +Of his adorers: He, to be avenged, +And to repair his numbers thus impaired, +Whether such virtue spent of old now failed +More Angels to create, if they at least +Are his created, or, to spite us more, +Determined to advance into our room +A creature formed of earth, and him endow, +Exalted from so base original, +With heavenly spoils, our spoils: What he decreed, +He effected; Man he made, and for him built +Magnificent this world, and earth his seat, +Him lord pronounced; and, O indignity! +Subjected to his service angel-wings, +And flaming ministers to watch and tend +Their earthly charge: Of these the vigilance +I dread; and, to elude, thus wrapt in mist +Of midnight vapour glide obscure, and pry +In every bush and brake, where hap may find +The serpent sleeping; in whose mazy folds +To hide me, and the dark intent I bring. +O foul descent! that I, who erst contended +With Gods to sit the highest, am now constrained +Into a beast; and, mixed with bestial slime, +This essence to incarnate and imbrute, +That to the highth of Deity aspired! +But what will not ambition and revenge +Descend to? Who aspires, must down as low +As high he soared; obnoxious, first or last, +To basest things. Revenge, at first though sweet, +Bitter ere long, back on itself recoils: +Let it; I reck not, so it light well aimed, +Since higher I fall short, on him who next +Provokes my envy, this new favourite +Of Heaven, this man of clay, son of despite, +Whom, us the more to spite, his Maker raised +From dust: Spite then with spite is best repaid. +So saying, through each thicket dank or dry, +Like a black mist low-creeping, he held on +His midnight-search, where soonest he might find +The serpent; him fast-sleeping soon he found +In labyrinth of many a round self-rolled, +His head the midst, well stored with subtile wiles: +Not yet in horrid shade or dismal den, +Nor nocent yet; but, on the grassy herb, +Fearless unfeared he slept: in at his mouth +The Devil entered; and his brutal sense, +In heart or head, possessing, soon inspired +With act intelligential; but his sleep +Disturbed not, waiting close the approach of morn. +Now, when as sacred light began to dawn +In Eden on the humid flowers, that breathed +Their morning incense, when all things, that breathe, +From the Earth's great altar send up silent praise +To the Creator, and his nostrils fill +With grateful smell, forth came the human pair, +And joined their vocal worship to the quire +Of creatures wanting voice; that done, partake +The season prime for sweetest scents and airs: +Then commune, how that day they best may ply +Their growing work: for much their work out-grew +The hands' dispatch of two gardening so wide, +And Eve first to her husband thus began. +Adam, well may we labour still to dress +This garden, still to tend plant, herb, and flower, +Our pleasant task enjoined; but, till more hands +Aid us, the work under our labour grows, +Luxurious by restraint; what we by day +Lop overgrown, or prune, or prop, or bind, +One night or two with wanton growth derides +Tending to wild. Thou therefore now advise, +Or bear what to my mind first thoughts present: +Let us divide our labours; thou, where choice +Leads thee, or where most needs, whether to wind +The woodbine round this arbour, or direct +The clasping ivy where to climb; while I, +In yonder spring of roses intermixed +With myrtle, find what to redress till noon: +For, while so near each other thus all day +Our task we choose, what wonder if so near +Looks intervene and smiles, or object new +Casual discourse draw on; which intermits +Our day's work, brought to little, though begun +Early, and the hour of supper comes unearned? +To whom mild answer Adam thus returned. +Sole Eve, associate sole, to me beyond +Compare above all living creatures dear! +Well hast thou motioned, well thy thoughts employed, +How we might best fulfil the work which here +God hath assigned us; nor of me shalt pass +Unpraised: for nothing lovelier can be found +In woman, than to study houshold good, +And good works in her husband to promote. +Yet not so strictly hath our Lord imposed +Labour, as to debar us when we need +Refreshment, whether food, or talk between, +Food of the mind, or this sweet intercourse +Of looks and smiles; for smiles from reason flow, +To brute denied, and are of love the food; +Love, not the lowest end of human life. +For not to irksome toil, but to delight, +He made us, and delight to reason joined. +These paths and bowers doubt not but our joint hands +Will keep from wilderness with ease, as wide +As we need walk, till younger hands ere long +Assist us; But, if much converse perhaps +Thee satiate, to short absence I could yield: +For solitude sometimes is best society, +And short retirement urges sweet return. +But other doubt possesses me, lest harm +Befall thee severed from me; for thou knowest +What hath been warned us, what malicious foe +Envying our happiness, and of his own +Despairing, seeks to work us woe and shame +By sly assault; and somewhere nigh at hand +Watches, no doubt, with greedy hope to find +His wish and best advantage, us asunder; +Hopeless to circumvent us joined, where each +To other speedy aid might lend at need: +Whether his first design be to withdraw +Our fealty from God, or to disturb +Conjugal love, than which perhaps no bliss +Enjoyed by us excites his envy more; +Or this, or worse, leave not the faithful side +That gave thee being, still shades thee, and protects. +The wife, where danger or dishonour lurks, +Safest and seemliest by her husband stays, +Who guards her, or with her the worst endures. +To whom the virgin majesty of Eve, +As one who loves, and some unkindness meets, +With sweet austere composure thus replied. +Offspring of Heaven and Earth, and all Earth's Lord! +That such an enemy we have, who seeks +Our ruin, both by thee informed I learn, +And from the parting Angel over-heard, +As in a shady nook I stood behind, +Just then returned at shut of evening flowers. +But, that thou shouldst my firmness therefore doubt +To God or thee, because we have a foe +May tempt it, I expected not to hear. +His violence thou fearest not, being such +As we, not capable of death or pain, +Can either not receive, or can repel. +His fraud is then thy fear; which plain infers +Thy equal fear, that my firm faith and love +Can by his fraud be shaken or seduced; +Thoughts, which how found they harbour in thy breast, +Adam, mis-thought of her to thee so dear? +To whom with healing words Adam replied. +Daughter of God and Man, immortal Eve! +For such thou art; from sin and blame entire: +Not diffident of thee do I dissuade +Thy absence from my sight, but to avoid +The attempt itself, intended by our foe. +For he who tempts, though in vain, at least asperses +The tempted with dishonour foul; supposed +Not incorruptible of faith, not proof +Against temptation: Thou thyself with scorn +And anger wouldst resent the offered wrong, +Though ineffectual found: misdeem not then, +If such affront I labour to avert +From thee alone, which on us both at once +The enemy, though bold, will hardly dare; +Or daring, first on me the assault shall light. +Nor thou his malice and false guile contemn; +Subtle he needs must be, who could seduce +Angels; nor think superfluous other's aid. +I, from the influence of thy looks, receive +Access in every virtue; in thy sight +More wise, more watchful, stronger, if need were +Of outward strength; while shame, thou looking on, +Shame to be overcome or over-reached, +Would utmost vigour raise, and raised unite. +Why shouldst not thou like sense within thee feel +When I am present, and thy trial choose +With me, best witness of thy virtue tried? +So spake domestick Adam in his care +And matrimonial love; but Eve, who thought +Less attributed to her faith sincere, +Thus her reply with accent sweet renewed. +If this be our condition, thus to dwell +In narrow circuit straitened by a foe, +Subtle or violent, we not endued +Single with like defence, wherever met; +How are we happy, still in fear of harm? +But harm precedes not sin: only our foe, +Tempting, affronts us with his foul esteem +Of our integrity: his foul esteem +Sticks no dishonour on our front, but turns +Foul on himself; then wherefore shunned or feared +By us? who rather double honour gain +From his surmise proved false; find peace within, +Favour from Heaven, our witness, from the event. +And what is faith, love, virtue, unassayed +Alone, without exteriour help sustained? +Let us not then suspect our happy state +Left so imperfect by the Maker wise, +As not secure to single or combined. +Frail is our happiness, if this be so, +And Eden were no Eden, thus exposed. +To whom thus Adam fervently replied. +O Woman, best are all things as the will +Of God ordained them: His creating hand +Nothing imperfect or deficient left +Of all that he created, much less Man, +Or aught that might his happy state secure, +Secure from outward force; within himself +The danger lies, yet lies within his power: +Against his will he can receive no harm. +But God left free the will; for what obeys +Reason, is free; and Reason he made right, +But bid her well be ware, and still erect; +Lest, by some fair-appearing good surprised, +She dictate false; and mis-inform the will +To do what God expressly hath forbid. +Not then mistrust, but tender love, enjoins, +That I should mind thee oft; and mind thou me. +Firm we subsist, yet possible to swerve; +Since Reason not impossibly may meet +Some specious object by the foe suborned, +And fall into deception unaware, +Not keeping strictest watch, as she was warned. +Seek not temptation then, which to avoid +Were better, and most likely if from me +Thou sever not: Trial will come unsought. +Wouldst thou approve thy constancy, approve +First thy obedience; the other who can know, +Not seeing thee attempted, who attest? +But, if thou think, trial unsought may find +Us both securer than thus warned thou seemest, +Go; for thy stay, not free, absents thee more; +Go in thy native innocence, rely +On what thou hast of virtue; summon all! +For God towards thee hath done his part, do thine. +So spake the patriarch of mankind; but Eve +Persisted; yet submiss, though last, replied. +With thy permission then, and thus forewarned +Chiefly by what thy own last reasoning words +Touched only; that our trial, when least sought, +May find us both perhaps far less prepared, +The willinger I go, nor much expect +A foe so proud will first the weaker seek; +So bent, the more shall shame him his repulse. +Thus saying, from her husband's hand her hand +Soft she withdrew; and, like a Wood-Nymph light, +Oread or Dryad, or of Delia's train, +Betook her to the groves; but Delia's self +In gait surpassed, and Goddess-like deport, +Though not as she with bow and quiver armed, +But with such gardening tools as Art yet rude, +Guiltless of fire, had formed, or Angels brought. +To Pales, or Pomona, thus adorned, +Likest she seemed, Pomona when she fled +Vertumnus, or to Ceres in her prime, +Yet virgin of Proserpina from Jove. +Her long with ardent look his eye pursued +Delighted, but desiring more her stay. +Oft he to her his charge of quick return +Repeated; she to him as oft engaged +To be returned by noon amid the bower, +And all things in best order to invite +Noontide repast, or afternoon's repose. +O much deceived, much failing, hapless Eve, +Of thy presumed return! event perverse! +Thou never from that hour in Paradise +Foundst either sweet repast, or sound repose; +Such ambush, hid among sweet flowers and shades, +Waited with hellish rancour imminent +To intercept thy way, or send thee back +Despoiled of innocence, of faith, of bliss! +For now, and since first break of dawn, the Fiend, +Mere serpent in appearance, forth was come; +And on his quest, where likeliest he might find +The only two of mankind, but in them +The whole included race, his purposed prey. +In bower and field he sought, where any tuft +Of grove or garden-plot more pleasant lay, +Their tendance, or plantation for delight; +By fountain or by shady rivulet +He sought them both, but wished his hap might find +Eve separate; he wished, but not with hope +Of what so seldom chanced; when to his wish, +Beyond his hope, Eve separate he spies, +Veiled in a cloud of fragrance, where she stood, +Half spied, so thick the roses blushing round +About her glowed, oft stooping to support +Each flower of slender stalk, whose head, though gay +Carnation, purple, azure, or specked with gold, +Hung drooping unsustained; them she upstays +Gently with myrtle band, mindless the while +Herself, though fairest unsupported flower, +From her best prop so far, and storm so nigh. +Nearer he drew, and many a walk traversed +Of stateliest covert, cedar, pine, or palm; +Then voluble and bold, now hid, now seen, +Among thick-woven arborets, and flowers +Imbordered on each bank, the hand of Eve: +Spot more delicious than those gardens feigned +Or of revived Adonis, or renowned +Alcinous, host of old Laertes' son; +Or that, not mystick, where the sapient king +Held dalliance with his fair Egyptian spouse. +Much he the place admired, the person more. +As one who long in populous city pent, +Where houses thick and sewers annoy the air, +Forth issuing on a summer's morn, to breathe +Among the pleasant villages and farms +Adjoined, from each thing met conceives delight; +The smell of grain, or tedded grass, or kine, +Or dairy, each rural sight, each rural sound; +If chance, with nymph-like step, fair virgin pass, +What pleasing seemed, for her now pleases more; +She most, and in her look sums all delight: +Such pleasure took the Serpent to behold +This flowery plat, the sweet recess of Eve +Thus early, thus alone: Her heavenly form +Angelick, but more soft, and feminine, +Her graceful innocence, her every air +Of gesture, or least action, overawed +His malice, and with rapine sweet bereaved +His fierceness of the fierce intent it brought: +That space the Evil-one abstracted stood +From his own evil, and for the time remained +Stupidly good; of enmity disarmed, +Of guile, of hate, of envy, of revenge: +But the hot Hell that always in him burns, +Though in mid Heaven, soon ended his delight, +And tortures him now more, the more he sees +Of pleasure, not for him ordained: then soon +Fierce hate he recollects, and all his thoughts +Of mischief, gratulating, thus excites. +Thoughts, whither have ye led me! with what sweet +Compulsion thus transported, to forget +What hither brought us! hate, not love;nor hope +Of Paradise for Hell, hope here to taste +Of pleasure; but all pleasure to destroy, +Save what is in destroying; other joy +To me is lost. Then, let me not let pass +Occasion which now smiles; behold alone +The woman, opportune to all attempts, +Her husband, for I view far round, not nigh, +Whose higher intellectual more I shun, +And strength, of courage haughty, and of limb +Heroick built, though of terrestrial mould; +Foe not informidable! exempt from wound, +I not; so much hath Hell debased, and pain +Enfeebled me, to what I was in Heaven. +She fair, divinely fair, fit love for Gods! +Not terrible, though terrour be in love +And beauty, not approached by stronger hate, +Hate stronger, under show of love well feigned; +The way which to her ruin now I tend. +So spake the enemy of mankind, enclosed +In serpent, inmate bad! and toward Eve +Addressed his way: not with indented wave, +Prone on the ground, as since; but on his rear, +Circular base of rising folds, that towered +Fold above fold, a surging maze! his head +Crested aloft, and carbuncle his eyes; +With burnished neck of verdant gold, erect +Amidst his circling spires, that on the grass +Floated redundant: pleasing was his shape +And lovely; never since of serpent-kind +Lovelier, not those that in Illyria changed, +Hermione and Cadmus, or the god +In Epidaurus; nor to which transformed +Ammonian Jove, or Capitoline, was seen; +He with Olympias; this with her who bore +Scipio, the highth of Rome. With tract oblique +At first, as one who sought access, but feared +To interrupt, side-long he works his way. +As when a ship, by skilful steersmen wrought +Nigh river's mouth or foreland, where the wind +Veers oft, as oft so steers, and shifts her sail: +So varied he, and of his tortuous train +Curled many a wanton wreath in sight of Eve, +To lure her eye; she, busied, heard the sound +Of rusling leaves, but minded not, as used +To such disport before her through the field, +From every beast; more duteous at her call, +Than at Circean call the herd disguised. +He, bolder now, uncalled before her stood, +But as in gaze admiring: oft he bowed +His turret crest, and sleek enamelled neck, +Fawning; and licked the ground whereon she trod. +His gentle dumb expression turned at length +The eye of Eve to mark his play; he, glad +Of her attention gained, with serpent-tongue +Organick, or impulse of vocal air, +His fraudulent temptation thus began. +Wonder not, sovran Mistress, if perhaps +Thou canst, who art sole wonder! much less arm +Thy looks, the Heaven of mildness, with disdain, +Displeased that I approach thee thus, and gaze +Insatiate; I thus single;nor have feared +Thy awful brow, more awful thus retired. +Fairest resemblance of thy Maker fair, +Thee all things living gaze on, all things thine +By gift, and thy celestial beauty adore +With ravishment beheld! there best beheld, +Where universally admired; but here +In this enclosure wild, these beasts among, +Beholders rude, and shallow to discern +Half what in thee is fair, one man except, +Who sees thee? and what is one? who should be seen +A Goddess among Gods, adored and served +By Angels numberless, thy daily train. +So glozed the Tempter, and his proem tuned: +Into the heart of Eve his words made way, +Though at the voice much marvelling; at length, +Not unamazed, she thus in answer spake. +What may this mean? language of man pronounced +By tongue of brute, and human sense expressed? +The first, at least, of these I thought denied +To beasts; whom God, on their creation-day, +Created mute to all articulate sound: +The latter I demur; for in their looks +Much reason, and in their actions, oft appears. +Thee, Serpent, subtlest beast of all the field +I knew, but not with human voice endued; +Redouble then this miracle, and say, +How camest thou speakable of mute, and how +To me so friendly grown above the rest +Of brutal kind, that daily are in sight? +Say, for such wonder claims attention due. +To whom the guileful Tempter thus replied. +Empress of this fair world, resplendent Eve! +Easy to me it is to tell thee all +What thou commandest; and right thou shouldst be obeyed: +I was at first as other beasts that graze +The trodden herb, of abject thoughts and low, +As was my food; nor aught but food discerned +Or sex, and apprehended nothing high: +Till, on a day roving the field, I chanced +A goodly tree far distant to behold +Loaden with fruit of fairest colours mixed, +Ruddy and gold: I nearer drew to gaze; +When from the boughs a savoury odour blown, +Grateful to appetite, more pleased my sense +Than smell of sweetest fennel, or the teats +Of ewe or goat dropping with milk at even, +Unsucked of lamb or kid, that tend their play. +To satisfy the sharp desire I had +Of tasting those fair apples, I resolved +Not to defer; hunger and thirst at once, +Powerful persuaders, quickened at the scent +Of that alluring fruit, urged me so keen. +About the mossy trunk I wound me soon; +For, high from ground, the branches would require +Thy utmost reach or Adam's: Round the tree +All other beasts that saw, with like desire +Longing and envying stood, but could not reach. +Amid the tree now got, where plenty hung +Tempting so nigh, to pluck and eat my fill +I spared not; for, such pleasure till that hour, +At feed or fountain, never had I found. +Sated at length, ere long I might perceive +Strange alteration in me, to degree +Of reason in my inward powers; and speech +Wanted not long; though to this shape retained. +Thenceforth to speculations high or deep +I turned my thoughts, and with capacious mind +Considered all things visible in Heaven, +Or Earth, or Middle; all things fair and good: +But all that fair and good in thy divine +Semblance, and in thy beauty's heavenly ray, +United I beheld; no fair to thine +Equivalent or second! which compelled +Me thus, though importune perhaps, to come +And gaze, and worship thee of right declared +Sovran of creatures, universal Dame! +So talked the spirited sly Snake; and Eve, +Yet more amazed, unwary thus replied. +Serpent, thy overpraising leaves in doubt +The virtue of that fruit, in thee first proved: +But say, where grows the tree? from hence how far? +For many are the trees of God that grow +In Paradise, and various, yet unknown +To us; in such abundance lies our choice, +As leaves a greater store of fruit untouched, +Still hanging incorruptible, till men +Grow up to their provision, and more hands +Help to disburden Nature of her birth. +To whom the wily Adder, blithe and glad. +Empress, the way is ready, and not long; +Beyond a row of myrtles, on a flat, +Fast by a fountain, one small thicket past +Of blowing myrrh and balm: if thou accept +My conduct, I can bring thee thither soon +Lead then, said Eve. He, leading, swiftly rolled +In tangles, and made intricate seem straight, +To mischief swift. Hope elevates, and joy +Brightens his crest; as when a wandering fire, +Compact of unctuous vapour, which the night +Condenses, and the cold environs round, +Kindled through agitation to a flame, +Which oft, they say, some evil Spirit attends, +Hovering and blazing with delusive light, +Misleads the amazed night-wanderer from his way +To bogs and mires, and oft through pond or pool; +There swallowed up and lost, from succour far. +So glistered the dire Snake, and into fraud +Led Eve, our credulous mother, to the tree +Of prohibition, root of all our woe; +Which when she saw, thus to her guide she spake. +Serpent, we might have spared our coming hither, +Fruitless to me, though fruit be here to excess, +The credit of whose virtue rest with thee; +Wonderous indeed, if cause of such effects. +But of this tree we may not taste nor touch; +God so commanded, and left that command +Sole daughter of his voice; the rest, we live +Law to ourselves; our reason is our law. +To whom the Tempter guilefully replied. +Indeed! hath God then said that of the fruit +Of all these garden-trees ye shall not eat, +Yet Lords declared of all in earth or air$? +To whom thus Eve, yet sinless. Of the fruit +Of each tree in the garden we may eat; +But of the fruit of this fair tree amidst +The garden, God hath said, Ye shall not eat +Thereof, nor shall ye touch it, lest ye die. +She scarce had said, though brief, when now more bold +The Tempter, but with show of zeal and love +To Man, and indignation at his wrong, +New part puts on; and, as to passion moved, +Fluctuates disturbed, yet comely and in act +Raised, as of some great matter to begin. +As when of old some orator renowned, +In Athens or free Rome, where eloquence +Flourished, since mute! to some great cause addressed, +Stood in himself collected; while each part, +Motion, each act, won audience ere the tongue; +Sometimes in highth began, as no delay +Of preface brooking, through his zeal of right: +So standing, moving, or to highth up grown, +The Tempter, all impassioned, thus began. +O sacred, wise, and wisdom-giving Plant, +Mother of science! now I feel thy power +Within me clear; not only to discern +Things in their causes, but to trace the ways +Of highest agents, deemed however wise. +Queen of this universe! do not believe +Those rigid threats of death: ye shall not die: +How should you? by the fruit? it gives you life +To knowledge; by the threatener? look on me, +Me, who have touched and tasted; yet both live, +And life more perfect have attained than Fate +Meant me, by venturing higher than my lot. +Shall that be shut to Man, which to the Beast +Is open? or will God incense his ire +For such a petty trespass? and not praise +Rather your dauntless virtue, whom the pain +Of death denounced, whatever thing death be, +Deterred not from achieving what might lead +To happier life, knowledge of good and evil; +Of good, how just? of evil, if what is evil +Be real, why not known, since easier shunned? +God therefore cannot hurt ye, and be just; +Not just, not God; not feared then, nor obeyed: +Your fear itself of death removes the fear. +Why then was this forbid? Why, but to awe; +Why, but to keep ye low and ignorant, +His worshippers? He knows that in the day +Ye eat thereof, your eyes that seem so clear, +Yet are but dim, shall perfectly be then +Opened and cleared, and ye shall be as Gods, +Knowing both good and evil, as they know. +That ye shall be as Gods, since I as Man, +Internal Man, is but proportion meet; +I, of brute, human; ye, of human, Gods. +So ye shall die perhaps, by putting off +Human, to put on Gods; death to be wished, +Though threatened, which no worse than this can bring. +And what are Gods, that Man may not become +As they, participating God-like food? +The Gods are first, and that advantage use +On our belief, that all from them proceeds: +I question it; for this fair earth I see, +Warmed by the sun, producing every kind; +Them, nothing: if they all things, who enclosed +Knowledge of good and evil in this tree, +That whoso eats thereof, forthwith attains +Wisdom without their leave? and wherein lies +The offence, that Man should thus attain to know? +What can your knowledge hurt him, or this tree +Impart against his will, if all be his? +Or is it envy? and can envy dwell +In heavenly breasts? These, these, and many more +Causes import your need of this fair fruit. +Goddess humane, reach then, and freely taste! +He ended; and his words, replete with guile, +Into her heart too easy entrance won: +Fixed on the fruit she gazed, which to behold +Might tempt alone; and in her ears the sound +Yet rung of his persuasive words, impregned +With reason, to her seeming, and with truth: +Mean while the hour of noon drew on, and waked +An eager appetite, raised by the smell +So savoury of that fruit, which with desire, +Inclinable now grown to touch or taste, +Solicited her longing eye; yet first +Pausing a while, thus to herself she mused. +Great are thy virtues, doubtless, best of fruits, +Though kept from man, and worthy to be admired; +Whose taste, too long forborn, at first assay +Gave elocution to the mute, and taught +The tongue not made for speech to speak thy praise: +Thy praise he also, who forbids thy use, +Conceals not from us, naming thee the tree +Of knowledge, knowledge both of good and evil; +Forbids us then to taste! but his forbidding +Commends thee more, while it infers the good +By thee communicated, and our want: +For good unknown sure is not had; or, had +And yet unknown, is as not had at all. +In plain then, what forbids he but to know, +Forbids us good, forbids us to be wise? +Such prohibitions bind not. But, if death +Bind us with after-bands, what profits then +Our inward freedom? In the day we eat +Of this fair fruit, our doom is, we shall die! +How dies the Serpent? he hath eaten and lives, +And knows, and speaks, and reasons, and discerns, +Irrational till then. For us alone +Was death invented? or to us denied +This intellectual food, for beasts reserved? +For beasts it seems: yet that one beast which first +Hath tasted envies not, but brings with joy +The good befallen him, author unsuspect, +Friendly to man, far from deceit or guile. +What fear I then? rather, what know to fear +Under this ignorance of good and evil, +Of God or death, of law or penalty? +Here grows the cure of all, this fruit divine, +Fair to the eye, inviting to the taste, +Of virtue to make wise: What hinders then +To reach, and feed at once both body and mind? +So saying, her rash hand in evil hour +Forth reaching to the fruit, she plucked, she eat! +Earth felt the wound; and Nature from her seat, +Sighing through all her works, gave signs of woe, +That all was lost. Back to the thicket slunk +The guilty Serpent; and well might;for Eve, +Intent now wholly on her taste, nought else +Regarded; such delight till then, as seemed, +In fruit she never tasted, whether true +Or fancied so, through expectation high +Of knowledge; not was Godhead from her thought. +Greedily she ingorged without restraint, +And knew not eating death: Satiate at length, +And hightened as with wine, jocund and boon, +Thus to herself she pleasingly began. +O sovran, virtuous, precious of all trees +In Paradise! of operation blest +To sapience, hitherto obscured, infamed. +And thy fair fruit let hang, as to no end +Created; but henceforth my early care, +Not without song, each morning, and due praise, +Shall tend thee, and the fertile burden ease +Of thy full branches offered free to all; +Till, dieted by thee, I grow mature +In knowledge, as the Gods, who all things know; +Though others envy what they cannot give: +For, had the gift been theirs, it had not here +Thus grown. Experience, next, to thee I owe, +Best guide; not following thee, I had remained +In ignorance; thou openest wisdom's way, +And givest access, though secret she retire. +And I perhaps am secret: Heaven is high, +High, and remote to see from thence distinct +Each thing on Earth; and other care perhaps +May have diverted from continual watch +Our great Forbidder, safe with all his spies +About him. But to Adam in what sort +Shall I appear? shall I to him make known +As yet my change, and give him to partake +Full happiness with me, or rather not, +But keeps the odds of knowledge in my power +Without copartner? so to add what wants +In female sex, the more to draw his love, +And render me more equal; and perhaps, +A thing not undesirable, sometime +Superiour; for, inferiour, who is free +This may be well: But what if God have seen, +And death ensue? then I shall be no more! +And Adam, wedded to another Eve, +Shall live with her enjoying, I extinct; +A death to think! Confirmed then I resolve, +Adam shall share with me in bliss or woe: +So dear I love him, that with him all deaths +I could endure, without him live no life. +So saying, from the tree her step she turned; +But first low reverence done, as to the Power +That dwelt within, whose presence had infused +Into the plant sciential sap, derived +From nectar, drink of Gods. Adam the while, +Waiting desirous her return, had wove +Of choicest flowers a garland, to adorn +Her tresses, and her rural labours crown; +As reapers oft are wont their harvest-queen. +Great joy he promised to his thoughts, and new +Solace in her return, so long delayed: +Yet oft his heart, divine of something ill, +Misgave him; he the faltering measure felt; +And forth to meet her went, the way she took +That morn when first they parted: by the tree +Of knowledge he must pass; there he her met, +Scarce from the tree returning; in her hand +A bough of fairest fruit, that downy smiled, +New gathered, and ambrosial smell diffused. +To him she hasted; in her face excuse +Came prologue, and apology too prompt; +Which, with bland words at will, she thus addressed. +Hast thou not wondered, Adam, at my stay? +Thee I have missed, and thought it long, deprived +Thy presence; agony of love till now +Not felt, nor shall be twice; for never more +Mean I to try, what rash untried I sought, +The pain of absence from thy sight. But strange +Hath been the cause, and wonderful to hear: +This tree is not, as we are told, a tree +Of danger tasted, nor to evil unknown +Opening the way, but of divine effect +To open eyes, and make them Gods who taste; +And hath been tasted such: The serpent wise, +Or not restrained as we, or not obeying, +Hath eaten of the fruit; and is become, +Not dead, as we are threatened, but thenceforth +Endued with human voice and human sense, +Reasoning to admiration; and with me +Persuasively hath so prevailed, that I +Have also tasted, and have also found +The effects to correspond; opener mine eyes, +Dim erst, dilated spirits, ampler heart, +And growing up to Godhead; which for thee +Chiefly I sought, without thee can despise. +For bliss, as thou hast part, to me is bliss; +Tedious, unshared with thee, and odious soon. +Thou therefore also taste, that equal lot +May join us, equal joy, as equal love; +Lest, thou not tasting, different degree +Disjoin us, and I then too late renounce +Deity for thee, when Fate will not permit. +Thus Eve with countenance blithe her story told; +But in her cheek distemper flushing glowed. +On the other side Adam, soon as he heard +The fatal trespass done by Eve, amazed, +Astonied stood and blank, while horrour chill +Ran through his veins, and all his joints relaxed; +From his slack hand the garland wreathed for Eve +Down dropt, and all the faded roses shed: +Speechless he stood and pale, till thus at length +First to himself he inward silence broke. +O fairest of Creation, last and best +Of all God's works, Creature in whom excelled +Whatever can to sight or thought be formed, +Holy, divine, good, amiable, or sweet! +How art thou lost! how on a sudden lost, +Defaced, deflowered, and now to death devote! +Rather, how hast thou yielded to transgress +The strict forbiddance, how to violate +The sacred fruit forbidden! Some cursed fraud +Of enemy hath beguiled thee, yet unknown, +And me with thee hath ruined; for with thee +Certain my resolution is to die: +How can I live without thee! how forego +Thy sweet converse, and love so dearly joined, +To live again in these wild woods forlorn! +Should God create another Eve, and I +Another rib afford, yet loss of thee +Would never from my heart: no, no!I feel +The link of Nature draw me: flesh of flesh, +Bone of my bone thou art, and from thy state +Mine never shall be parted, bliss or woe. +So having said, as one from sad dismay +Recomforted, and after thoughts disturbed +Submitting to what seemed remediless, +Thus in calm mood his words to Eve he turned. +Bold deed thou hast presumed, adventurous Eve, +And peril great provoked, who thus hast dared, +Had it been only coveting to eye +That sacred fruit, sacred to abstinence, +Much more to taste it under ban to touch. +But past who can recall, or done undo? +Not God Omnipotent, nor Fate; yet so +Perhaps thou shalt not die, perhaps the fact +Is not so heinous now, foretasted fruit, +Profaned first by the serpent, by him first +Made common, and unhallowed, ere our taste; +Nor yet on him found deadly; yet he lives; +Lives, as thou saidst, and gains to live, as Man, +Higher degree of life; inducement strong +To us, as likely tasting to attain +Proportional ascent; which cannot be +But to be Gods, or Angels, demi-Gods. +Nor can I think that God, Creator wise, +Though threatening, will in earnest so destroy +Us his prime creatures, dignified so high, +Set over all his works; which in our fall, +For us created, needs with us must fail, +Dependant made; so God shall uncreate, +Be frustrate, do, undo, and labour lose; +Not well conceived of God, who, though his power +Creation could repeat, yet would be loth +Us to abolish, lest the Adversary +Triumph, and say; "Fickle their state whom God +"Most favours; who can please him long? Me first +"He ruined, now Mankind; whom will he next?" +Matter of scorn, not to be given the Foe. +However I with thee have fixed my lot, +Certain to undergo like doom: If death +Consort with thee, death is to me as life; +So forcible within my heart I feel +The bond of Nature draw me to my own; +My own in thee, for what thou art is mine; +Our state cannot be severed; we are one, +One flesh; to lose thee were to lose myself. +So Adam; and thus Eve to him replied. +O glorious trial of exceeding love, +Illustrious evidence, example high! +Engaging me to emulate; but, short +Of thy perfection, how shall I attain, +Adam, from whose dear side I boast me sprung, +And gladly of our union hear thee speak, +One heart, one soul in both; whereof good proof +This day affords, declaring thee resolved, +Rather than death, or aught than death more dread, +Shall separate us, linked in love so dear, +To undergo with me one guilt, one crime, +If any be, of tasting this fair fruit; +Whose virtue for of good still good proceeds, +Direct, or by occasion, hath presented +This happy trial of thy love, which else +So eminently never had been known? +Were it I thought death menaced would ensue +This my attempt, I would sustain alone +The worst, and not persuade thee, rather die +Deserted, than oblige thee with a fact +Pernicious to thy peace; chiefly assured +Remarkably so late of thy so true, +So faithful, love unequalled: but I feel +Far otherwise the event; not death, but life +Augmented, opened eyes, new hopes, new joys, +Taste so divine, that what of sweet before +Hath touched my sense, flat seems to this, and harsh. +On my experience, Adam, freely taste, +And fear of death deliver to the winds. +So saying, she embraced him, and for joy +Tenderly wept; much won, that he his love +Had so ennobled, as of choice to incur +Divine displeasure for her sake, or death. +In recompence for such compliance bad +Such recompence best merits from the bough +She gave him of that fair enticing fruit +With liberal hand: he scrupled not to eat, +Against his better knowledge; not deceived, +But fondly overcome with female charm. +Earth trembled from her entrails, as again +In pangs; and Nature gave a second groan; +Sky loured; and, muttering thunder, some sad drops +Wept at completing of the mortal sin +Original: while Adam took no thought, +Eating his fill; nor Eve to iterate +Her former trespass feared, the more to sooth +Him with her loved society; that now, +As with new wine intoxicated both, +They swim in mirth, and fancy that they feel +Divinity within them breeding wings, +Wherewith to scorn the earth: But that false fruit +Far other operation first displayed, +Carnal desire inflaming; he on Eve +Began to cast lascivious eyes; she him +As wantonly repaid; in lust they burn: +Till Adam thus 'gan Eve to dalliance move. +Eve, now I see thou art exact of taste, +And elegant, of sapience no small part; +Since to each meaning savour we apply, +And palate call judicious; I the praise +Yield thee, so well this day thou hast purveyed. +Much pleasure we have lost, while we abstained +From this delightful fruit, nor known till now +True relish, tasting; if such pleasure be +In things to us forbidden, it might be wished, +For this one tree had been forbidden ten. +But come, so well refreshed, now let us play, +As meet is, after such delicious fare; +For never did thy beauty, since the day +I saw thee first and wedded thee, adorned +With all perfections, so inflame my sense +With ardour to enjoy thee, fairer now +Than ever; bounty of this virtuous tree! +So said he, and forbore not glance or toy +Of amorous intent; well understood +Of Eve, whose eye darted contagious fire. +Her hand he seised; and to a shady bank, +Thick over-head with verdant roof imbowered, +He led her nothing loth; flowers were the couch, +Pansies, and violets, and asphodel, +And hyacinth; Earth's freshest softest lap. +There they their fill of love and love's disport +Took largely, of their mutual guilt the seal, +The solace of their sin; till dewy sleep +Oppressed them, wearied with their amorous play, +Soon as the force of that fallacious fruit, +That with exhilarating vapour bland +About their spirits had played, and inmost powers +Made err, was now exhaled; and grosser sleep, +Bred of unkindly fumes, with conscious dreams +Incumbered, now had left them; up they rose +As from unrest; and, each the other viewing, +Soon found their eyes how opened, and their minds +How darkened; innocence, that as a veil +Had shadowed them from knowing ill, was gone; +Just confidence, and native righteousness, +And honour, from about them, naked left +To guilty Shame; he covered, but his robe +Uncovered more. So rose the Danite strong, +Herculean Samson, from the harlot-lap +Of Philistean Dalilah, and waked +Shorn of his strength. They destitute and bare +Of all their virtue: Silent, and in face +Confounded, long they sat, as strucken mute: +Till Adam, though not less than Eve abashed, +At length gave utterance to these words constrained. +O Eve, in evil hour thou didst give ear +To that false worm, of whomsoever taught +To counterfeit Man's voice; true in our fall, +False in our promised rising; since our eyes +Opened we find indeed, and find we know +Both good and evil; good lost, and evil got; +Bad fruit of knowledge, if this be to know; +Which leaves us naked thus, of honour void, +Of innocence, of faith, of purity, +Our wonted ornaments now soiled and stained, +And in our faces evident the signs +Of foul concupiscence; whence evil store; +Even shame, the last of evils; of the first +Be sure then.--How shall I behold the face +Henceforth of God or Angel, erst with joy +And rapture so oft beheld? Those heavenly shapes +Will dazzle now this earthly with their blaze +Insufferably bright. O! might I here +In solitude live savage; in some glade +Obscured, where highest woods, impenetrable +To star or sun-light, spread their umbrage broad +And brown as evening: Cover me, ye Pines! +Ye Cedars, with innumerable boughs +Hide me, where I may never see them more!-- +But let us now, as in bad plight, devise +What best may for the present serve to hide +The parts of each from other, that seem most +To shame obnoxious, and unseemliest seen; +Some tree, whose broad smooth leaves together sewed, +And girded on our loins, may cover round +Those middle parts; that this new comer, Shame, +There sit not, and reproach us as unclean. +So counselled he, and both together went +Into the thickest wood; there soon they chose +The fig-tree; not that kind for fruit renowned, +But such as at this day, to Indians known, +In Malabar or Decan spreads her arms +Branching so broad and long, that in the ground +The bended twigs take root, and daughters grow +About the mother tree, a pillared shade +High over-arched, and echoing walks between: +There oft the Indian herdsman, shunning heat, +Shelters in cool, and tends his pasturing herds +At loop-holes cut through thickest shade: Those leaves +They gathered, broad as Amazonian targe; +And, with what skill they had, together sewed, +To gird their waist; vain covering, if to hide +Their guilt and dreaded shame! O, how unlike +To that first naked glory! Such of late +Columbus found the American, so girt +With feathered cincture; naked else, and wild +Among the trees on isles and woody shores. +Thus fenced, and, as they thought, their shame in part +Covered, but not at rest or ease of mind, +They sat them down to weep; nor only tears +Rained at their eyes, but high winds worse within +Began to rise, high passions, anger, hate, +Mistrust, suspicion, discord; and shook sore +Their inward state of mind, calm region once +And full of peace, now tost and turbulent: +For Understanding ruled not, and the Will +Heard not her lore; both in subjection now +To sensual Appetite, who from beneath +Usurping over sovran Reason claimed +Superiour sway: From thus distempered breast, +Adam, estranged in look and altered style, +Speech intermitted thus to Eve renewed. +Would thou hadst hearkened to my words, and staid +With me, as I besought thee, when that strange +Desire of wandering, this unhappy morn, +I know not whence possessed thee; we had then +Remained still happy; not, as now, despoiled +Of all our good; shamed, naked, miserable! +Let none henceforth seek needless cause to approve +The faith they owe; when earnestly they seek +Such proof, conclude, they then begin to fail. +To whom, soon moved with touch of blame, thus Eve. +What words have passed thy lips, Adam severe! +Imputest thou that to my default, or will +Of wandering, as thou callest it, which who knows +But might as ill have happened thou being by, +Or to thyself perhaps? Hadst thou been there, +Or here the attempt, thou couldst not have discerned +Fraud in the Serpent, speaking as he spake; +No ground of enmity between us known, +Why he should mean me ill, or seek to harm. +Was I to have never parted from thy side? +As good have grown there still a lifeless rib. +Being as I am, why didst not thou, the head, +Command me absolutely not to go, +Going into such danger, as thou saidst? +Too facile then, thou didst not much gainsay; +Nay, didst permit, approve, and fair dismiss. +Hadst thou been firm and fixed in thy dissent, +Neither had I transgressed, nor thou with me. +To whom, then first incensed, Adam replied. +Is this the love, is this the recompence +Of mine to thee, ingrateful Eve! expressed +Immutable, when thou wert lost, not I; +Who might have lived, and joyed immortal bliss, +Yet willingly chose rather death with thee? +And am I now upbraided as the cause +Of thy transgressing? Not enough severe, +It seems, in thy restraint: What could I more +I warned thee, I admonished thee, foretold +The danger, and the lurking enemy +That lay in wait; beyond this, had been force; +And force upon free will hath here no place. +But confidence then bore thee on; secure +Either to meet no danger, or to find +Matter of glorious trial; and perhaps +I also erred, in overmuch admiring +What seemed in thee so perfect, that I thought +No evil durst attempt thee; but I rue +The errour now, which is become my crime, +And thou the accuser. Thus it shall befall +Him, who, to worth in women overtrusting, +Lets her will rule: restraint she will not brook; +And, left to herself, if evil thence ensue, +She first his weak indulgence will accuse. +Thus they in mutual accusation spent +The fruitless hours, but neither self-condemning; +And of their vain contest appeared no end. + + + +Book X + + +Mean while the heinous and despiteful act +Of Satan, done in Paradise; and how +He, in the serpent, had perverted Eve, +Her husband she, to taste the fatal fruit, +Was known in Heaven; for what can 'scape the eye +Of God all-seeing, or deceive his heart +Omniscient? who, in all things wise and just, +Hindered not Satan to attempt the mind +Of Man, with strength entire and free will armed, +Complete to have discovered and repulsed +Whatever wiles of foe or seeming friend. +For still they knew, and ought to have still remembered, +The high injunction, not to taste that fruit, +Whoever tempted; which they not obeying, +(Incurred what could they less?) the penalty; +And, manifold in sin, deserved to fall. +Up into Heaven from Paradise in haste +The angelick guards ascended, mute, and sad, +For Man; for of his state by this they knew, +Much wondering how the subtle Fiend had stolen +Entrance unseen. Soon as the unwelcome news +From Earth arrived at Heaven-gate, displeased +All were who heard; dim sadness did not spare +That time celestial visages, yet, mixed +With pity, violated not their bliss. +About the new-arrived, in multitudes +The ethereal people ran, to hear and know +How all befel: They towards the throne supreme, +Accountable, made haste, to make appear, +With righteous plea, their utmost vigilance +And easily approved; when the Most High +Eternal Father, from his secret cloud, +Amidst in thunder uttered thus his voice. +Assembled Angels, and ye Powers returned +From unsuccessful charge; be not dismayed, +Nor troubled at these tidings from the earth, +Which your sincerest care could not prevent; +Foretold so lately what would come to pass, +When first this tempter crossed the gulf from Hell. +I told ye then he should prevail, and speed +On his bad errand; Man should be seduced, +And flattered out of all, believing lies +Against his Maker; no decree of mine +Concurring to necessitate his fall, +Or touch with lightest moment of impulse +His free will, to her own inclining left +In even scale. But fallen he is; and now +What rests, but that the mortal sentence pass +On his transgression,--death denounced that day? +Which he presumes already vain and void, +Because not yet inflicted, as he feared, +By some immediate stroke; but soon shall find +Forbearance no acquittance, ere day end. +Justice shall not return as bounty scorned. +But whom send I to judge them? whom but thee, +Vicegerent Son? To thee I have transferred +All judgement, whether in Heaven, or Earth, or Hell. +Easy it may be seen that I intend +Mercy colleague with justice, sending thee +Man's friend, his Mediator, his designed +Both ransom and Redeemer voluntary, +And destined Man himself to judge Man fallen. +So spake the Father; and, unfolding bright +Toward the right hand his glory, on the Son +Blazed forth unclouded Deity: He full +Resplendent all his Father manifest +Expressed, and thus divinely answered mild. +Father Eternal, thine is to decree; +Mine, both in Heaven and Earth, to do thy will +Supreme; that thou in me, thy Son beloved, +Mayest ever rest well pleased. I go to judge +On earth these thy transgressours; but thou knowest, +Whoever judged, the worst on me must light, +When time shall be; for so I undertook +Before thee; and, not repenting, this obtain +Of right, that I may mitigate their doom +On me derived; yet I shall temper so +Justice with mercy, as may illustrate most +Them fully satisfied, and thee appease. +Attendance none shall need, nor train, where none +Are to behold the judgement, but the judged, +Those two; the third best absent is condemned, +Convict by flight, and rebel to all law: +Conviction to the serpent none belongs. +Thus saying, from his radiant seat he rose +Of high collateral glory: Him Thrones, and Powers, +Princedoms, and Dominations ministrant, +Accompanied to Heaven-gate; from whence +Eden, and all the coast, in prospect lay. +Down he descended straight; the speed of Gods +Time counts not, though with swiftest minutes winged. +Now was the sun in western cadence low +From noon, and gentle airs, due at their hour, +To fan the earth now waked, and usher in +The evening cool; when he, from wrath more cool, +Came the mild Judge, and Intercessour both, +To sentence Man: The voice of God they heard +Now walking in the garden, by soft winds +Brought to their ears, while day declined; they heard, +And from his presence hid themselves among +The thickest trees, both man and wife; till God, +Approaching, thus to Adam called aloud. +Where art thou, Adam, wont with joy to meet +My coming seen far off? I miss thee here, +Not pleased, thus entertained with solitude, +Where obvious duty ere while appeared unsought: +Or come I less conspicuous, or what change +Absents thee, or what chance detains?--Come forth! +He came; and with him Eve, more loth, though first +To offend; discountenanced both, and discomposed; +Love was not in their looks, either to God, +Or to each other; but apparent guilt, +And shame, and perturbation, and despair, +Anger, and obstinacy, and hate, and guile. +Whence Adam, faltering long, thus answered brief. +I heard thee in the garden, and of thy voice +Afraid, being naked, hid myself. To whom +The gracious Judge without revile replied. +My voice thou oft hast heard, and hast not feared, +But still rejoiced; how is it now become +So dreadful to thee? That thou art naked, who +Hath told thee? Hast thou eaten of the tree, +Whereof I gave thee charge thou shouldst not eat? +To whom thus Adam sore beset replied. +O Heaven! in evil strait this day I stand +Before my Judge; either to undergo +Myself the total crime, or to accuse +My other self, the partner of my life; +Whose failing, while her faith to me remains, +I should conceal, and not expose to blame +By my complaint: but strict necessity +Subdues me, and calamitous constraint; +Lest on my head both sin and punishment, +However insupportable, be all +Devolved; though should I hold my peace, yet thou +Wouldst easily detect what I conceal.-- +This Woman, whom thou madest to be my help, +And gavest me as thy perfect gift, so good, +So fit, so acceptable, so divine, +That from her hand I could suspect no ill, +And what she did, whatever in itself, +Her doing seemed to justify the deed; +She gave me of the tree, and I did eat. +To whom the Sovran Presence thus replied. +Was she thy God, that her thou didst obey +Before his voice? or was she made thy guide, +Superiour, or but equal, that to her +Thou didst resign thy manhood, and the place +Wherein God set thee above her made of thee, +And for thee, whose perfection far excelled +Hers in all real dignity? Adorned +She was indeed, and lovely, to attract +Thy love, not thy subjection; and her gifts +Were such, as under government well seemed; +Unseemly to bear rule; which was thy part +And person, hadst thou known thyself aright. +So having said, he thus to Eve in few. +Say, Woman, what is this which thou hast done? +To whom sad Eve, with shame nigh overwhelmed, +Confessing soon, yet not before her Judge +Bold or loquacious, thus abashed replied. +The Serpent me beguiled, and I did eat. +Which when the Lord God heard, without delay +To judgement he proceeded on the accused +Serpent, though brute; unable to transfer +The guilt on him, who made him instrument +Of mischief, and polluted from the end +Of his creation; justly then accursed, +As vitiated in nature: More to know +Concerned not Man, (since he no further knew) +Nor altered his offence; yet God at last +To Satan first in sin his doom applied, +Though in mysterious terms, judged as then best: +And on the Serpent thus his curse let fall. +Because thou hast done this, thou art accursed +Above all cattle, each beast of the field; +Upon thy belly groveling thou shalt go, +And dust shalt eat all the days of thy life. +Between thee and the woman I will put +Enmity, and between thine and her seed; +Her seed shall bruise thy head, thou bruise his heel. +So spake this oracle, then verified +When Jesus, Son of Mary, second Eve, +Saw Satan fall, like lightning, down from Heaven, +Prince of the air; then, rising from his grave +Spoiled Principalities and Powers, triumphed +In open show; and, with ascension bright, +Captivity led captive through the air, +The realm itself of Satan, long usurped; +Whom he shall tread at last under our feet; +Even he, who now foretold his fatal bruise; +And to the Woman thus his sentence turned. +Thy sorrow I will greatly multiply +By thy conception; children thou shalt bring +In sorrow forth; and to thy husband's will +Thine shall submit; he over thee shall rule. +On Adam last thus judgement he pronounced. +Because thou hast hearkened to the voice of thy wife, +And eaten of the tree, concerning which +I charged thee, saying, Thou shalt not eat thereof: +Cursed is the ground for thy sake; thou in sorrow +Shalt eat thereof, all the days of thy life; +Thorns also and thistles it shall bring thee forth +Unbid; and thou shalt eat the herb of the field; +In the sweat of thy face shalt thou eat bread, +Till thou return unto the ground; for thou +Out of the ground wast taken, know thy birth, +For dust thou art, and shalt to dust return. +So judged he Man, both Judge and Saviour sent; +And the instant stroke of death, denounced that day, +Removed far off; then, pitying how they stood +Before him naked to the air, that now +Must suffer change, disdained not to begin +Thenceforth the form of servant to assume; +As when he washed his servants feet; so now, +As father of his family, he clad +Their nakedness with skins of beasts, or slain, +Or as the snake with youthful coat repaid; +And thought not much to clothe his enemies; +Nor he their outward only with the skins +Of beasts, but inward nakedness, much more. +Opprobrious, with his robe of righteousness, +Arraying, covered from his Father's sight. +To him with swift ascent he up returned, +Into his blissful bosom reassumed +In glory, as of old; to him appeased +All, though all-knowing, what had passed with Man +Recounted, mixing intercession sweet. +Mean while, ere thus was sinned and judged on Earth, +Within the gates of Hell sat Sin and Death, +In counterview within the gates, that now +Stood open wide, belching outrageous flame +Far into Chaos, since the Fiend passed through, +Sin opening; who thus now to Death began. +O Son, why sit we here each other viewing +Idly, while Satan, our great author, thrives +In other worlds, and happier seat provides +For us, his offspring dear? It cannot be +But that success attends him; if mishap, +Ere this he had returned, with fury driven +By his avengers; since no place like this +Can fit his punishment, or their revenge. +Methinks I feel new strength within me rise, +Wings growing, and dominion given me large +Beyond this deep; whatever draws me on, +Or sympathy, or some connatural force, +Powerful at greatest distance to unite, +With secret amity, things of like kind, +By secretest conveyance. Thou, my shade +Inseparable, must with me along; +For Death from Sin no power can separate. +But, lest the difficulty of passing back +Stay his return perhaps over this gulf +Impassable, impervious; let us try +Adventurous work, yet to thy power and mine +Not unagreeable, to found a path +Over this main from Hell to that new world, +Where Satan now prevails; a monument +Of merit high to all the infernal host, +Easing their passage hence, for intercourse, +Or transmigration, as their lot shall lead. +Nor can I miss the way, so strongly drawn +By this new-felt attraction and instinct. +Whom thus the meager Shadow answered soon. +Go, whither Fate, and inclination strong, +Leads thee; I shall not lag behind, nor err +The way, thou leading; such a scent I draw +Of carnage, prey innumerable, and taste +The savour of death from all things there that live: +Nor shall I to the work thou enterprisest +Be wanting, but afford thee equal aid. +So saying, with delight he snuffed the smell +Of mortal change on earth. As when a flock +Of ravenous fowl, though many a league remote, +Against the day of battle, to a field, +Where armies lie encamped, come flying, lured +With scent of living carcasses designed +For death, the following day, in bloody fight: +So scented the grim Feature, and upturned +His nostril wide into the murky air; +Sagacious of his quarry from so far. +Then both from out Hell-gates, into the waste +Wide anarchy of Chaos, damp and dark, +Flew diverse; and with power (their power was great) +Hovering upon the waters, what they met +Solid or slimy, as in raging sea +Tost up and down, together crouded drove, +From each side shoaling towards the mouth of Hell; +As when two polar winds, blowing adverse +Upon the Cronian sea, together drive +Mountains of ice, that stop the imagined way +Beyond Petsora eastward, to the rich +Cathaian coast. The aggregated soil +Death with his mace petrifick, cold and dry, +As with a trident, smote; and fixed as firm +As Delos, floating once; the rest his look +Bound with Gorgonian rigour not to move; +And with Asphaltick slime, broad as the gate, +Deep to the roots of Hell the gathered beach +They fastened, and the mole immense wrought on +Over the foaming deep high-arched, a bridge +Of length prodigious, joining to the wall +Immoveable of this now fenceless world, +Forfeit to Death; from hence a passage broad, +Smooth, easy, inoffensive, down to Hell. +So, if great things to small may be compared, +Xerxes, the liberty of Greece to yoke, +From Susa, his Memnonian palace high, +Came to the sea: and, over Hellespont +Bridging his way, Europe with Asia joined, +And scourged with many a stroke the indignant waves. +Now had they brought the work by wonderous art +Pontifical, a ridge of pendant rock, +Over the vexed abyss, following the track +Of Satan to the self-same place where he +First lighted from his wing, and landed safe +From out of Chaos, to the outside bare +Of this round world: With pins of adamant +And chains they made all fast, too fast they made +And durable! And now in little space +The confines met of empyrean Heaven, +And of this World; and, on the left hand, Hell +With long reach interposed; three several ways +In sight, to each of these three places led. +And now their way to Earth they had descried, +To Paradise first tending; when, behold! +Satan, in likeness of an Angel bright, +Betwixt the Centaur and the Scorpion steering +His zenith, while the sun in Aries rose: +Disguised he came; but those his children dear +Their parent soon discerned, though in disguise. +He, after Eve seduced, unminded slunk +Into the wood fast by; and, changing shape, +To observe the sequel, saw his guileful act +By Eve, though all unweeting, seconded +Upon her husband; saw their shame that sought +Vain covertures; but when he saw descend +The Son of God to judge them, terrified +He fled; not hoping to escape, but shun +The present; fearing, guilty, what his wrath +Might suddenly inflict; that past, returned +By night, and listening where the hapless pair +Sat in their sad discourse, and various plaint, +Thence gathered his own doom; which understood +Not instant, but of future time, with joy +And tidings fraught, to Hell he now returned; +And at the brink of Chaos, near the foot +Of this new wonderous pontifice, unhoped +Met, who to meet him came, his offspring dear. +Great joy was at their meeting, and at sight +Of that stupendious bridge his joy encreased. +Long he admiring stood, till Sin, his fair +Enchanting daughter, thus the silence broke. +O Parent, these are thy magnifick deeds, +Thy trophies! which thou viewest as not thine own; +Thou art their author, and prime architect: +For I no sooner in my heart divined, +My heart, which by a secret harmony +Still moves with thine, joined in connexion sweet, +That thou on earth hadst prospered, which thy looks +Now also evidence, but straight I felt, +Though distant from thee worlds between, yet felt, +That I must after thee, with this thy son; +Such fatal consequence unites us three! +Hell could no longer hold us in our bounds, +Nor this unvoyageable gulf obscure +Detain from following thy illustrious track. +Thou hast achieved our liberty, confined +Within Hell-gates till now; thou us impowered +To fortify thus far, and overlay, +With this portentous bridge, the dark abyss. +Thine now is all this world; thy virtue hath won +What thy hands builded not; thy wisdom gained +With odds what war hath lost, and fully avenged +Our foil in Heaven; here thou shalt monarch reign, +There didst not; there let him still victor sway, +As battle hath adjudged; from this new world +Retiring, by his own doom alienated; +And henceforth monarchy with thee divide +Of all things, parted by the empyreal bounds, +His quadrature, from thy orbicular world; +Or try thee now more dangerous to his throne. +Whom thus the Prince of darkness answered glad. +Fair Daughter, and thou Son and Grandchild both; +High proof ye now have given to be the race +Of Satan (for I glory in the name, +Antagonist of Heaven's Almighty King,) +Amply have merited of me, of all +The infernal empire, that so near Heaven's door +Triumphal with triumphal act have met, +Mine, with this glorious work; and made one realm, +Hell and this world, one realm, one continent +Of easy thorough-fare. Therefore, while I +Descend through darkness, on your road with ease, +To my associate Powers, them to acquaint +With these successes, and with them rejoice; +You two this way, among these numerous orbs, +All yours, right down to Paradise descend; +There dwell, and reign in bliss; thence on the earth +Dominion exercise and in the air, +Chiefly on Man, sole lord of all declared; +Him first make sure your thrall, and lastly kill. +My substitutes I send ye, and create +Plenipotent on earth, of matchless might +Issuing from me: on your joint vigour now +My hold of this new kingdom all depends, +Through Sin to Death exposed by my exploit. +If your joint power prevail, the affairs of Hell +No detriment need fear; go, and be strong! +So saying he dismissed them; they with speed +Their course through thickest constellations held, +Spreading their bane; the blasted stars looked wan, +And planets, planet-struck, real eclipse +Then suffered. The other way Satan went down +The causey to Hell-gate: On either side +Disparted Chaos overbuilt exclaimed, +And with rebounding surge the bars assailed, +That scorned his indignation: Through the gate, +Wide open and unguarded, Satan passed, +And all about found desolate; for those, +Appointed to sit there, had left their charge, +Flown to the upper world; the rest were all +Far to the inland retired, about the walls +Of Pandemonium; city and proud seat +Of Lucifer, so by allusion called +Of that bright star to Satan paragoned; +There kept their watch the legions, while the Grand +In council sat, solicitous what chance +Might intercept their emperour sent; so he +Departing gave command, and they observed. +As when the Tartar from his Russian foe, +By Astracan, over the snowy plains, +Retires; or Bactrin Sophi, from the horns +Of Turkish crescent, leaves all waste beyond +The realm of Aladule, in his retreat +To Tauris or Casbeen: So these, the late +Heaven-banished host, left desart utmost Hell +Many a dark league, reduced in careful watch +Round their metropolis; and now expecting +Each hour their great adventurer, from the search +Of foreign worlds: He through the midst unmarked, +In show plebeian Angel militant +Of lowest order, passed; and from the door +Of that Plutonian hall, invisible +Ascended his high throne; which, under state +Of richest texture spread, at the upper end +Was placed in regal lustre. Down a while +He sat, and round about him saw unseen: +At last, as from a cloud, his fulgent head +And shape star-bright appeared, or brighter; clad +With what permissive glory since his fall +Was left him, or false glitter: All amazed +At that so sudden blaze the Stygian throng +Bent their aspect, and whom they wished beheld, +Their mighty Chief returned: loud was the acclaim: +Forth rushed in haste the great consulting peers, +Raised from their dark Divan, and with like joy +Congratulant approached him; who with hand +Silence, and with these words attention, won. +Thrones, Dominations, Princedoms, Virtues, Powers; +For in possession such, not only of right, +I call ye, and declare ye now; returned +Successful beyond hope, to lead ye forth +Triumphant out of this infernal pit +Abominable, accursed, the house of woe, +And dungeon of our tyrant: Now possess, +As Lords, a spacious world, to our native Heaven +Little inferiour, by my adventure hard +With peril great achieved. Long were to tell +What I have done; what suffered;with what pain +Voyaged th' unreal, vast, unbounded deep +Of horrible confusion; over which +By Sin and Death a broad way now is paved, +To expedite your glorious march; but I +Toiled out my uncouth passage, forced to ride +The untractable abyss, plunged in the womb +Of unoriginal Night and Chaos wild; +That, jealous of their secrets, fiercely opposed +My journey strange, with clamorous uproar +Protesting Fate supreme; thence how I found +The new created world, which fame in Heaven +Long had foretold, a fabrick wonderful +Of absolute perfection! therein Man +Placed in a Paradise, by our exile +Made happy: Him by fraud I have seduced +From his Creator; and, the more to encrease +Your wonder, with an apple; he, thereat +Offended, worth your laughter! hath given up +Both his beloved Man, and all his world, +To Sin and Death a prey, and so to us, +Without our hazard, labour, or alarm; +To range in, and to dwell, and over Man +To rule, as over all he should have ruled. +True is, me also he hath judged, or rather +Me not, but the brute serpent in whose shape +Man I deceived: that which to me belongs, +Is enmity which he will put between +Me and mankind; I am to bruise his heel; +His seed, when is not set, shall bruise my head: +A world who would not purchase with a bruise, +Or much more grievous pain?--Ye have the account +Of my performance: What remains, ye Gods, +But up, and enter now into full bliss? +So having said, a while he stood, expecting +Their universal shout, and high applause, +To fill his ear; when, contrary, he hears +On all sides, from innumerable tongues, +A dismal universal hiss, the sound +Of publick scorn; he wondered, but not long +Had leisure, wondering at himself now more, +His visage drawn he felt to sharp and spare; +His arms clung to his ribs; his legs entwining +Each other, till supplanted down he fell +A monstrous serpent on his belly prone, +Reluctant, but in vain; a greater power +Now ruled him, punished in the shape he sinned, +According to his doom: he would have spoke, +But hiss for hiss returned with forked tongue +To forked tongue; for now were all transformed +Alike, to serpents all, as accessories +To his bold riot: Dreadful was the din +Of hissing through the hall, thick swarming now +With complicated monsters head and tail, +Scorpion, and Asp, and Amphisbaena dire, +Cerastes horned, Hydrus, and Elops drear, +And Dipsas; (not so thick swarmed once the soil +Bedropt with blood of Gorgon, or the isle +Ophiusa,) but still greatest he the midst, +Now Dragon grown, larger than whom the sun +Ingendered in the Pythian vale or slime, +Huge Python, and his power no less he seemed +Above the rest still to retain; they all +Him followed, issuing forth to the open field, +Where all yet left of that revolted rout, +Heaven-fallen, in station stood or just array; +Sublime with expectation when to see +In triumph issuing forth their glorious Chief; +They saw, but other sight instead! a croud +Of ugly serpents; horrour on them fell, +And horrid sympathy; for, what they saw, +They felt themselves, now changing; down their arms, +Down fell both spear and shield; down they as fast; +And the dire hiss renewed, and the dire form +Catched, by contagion; like in punishment, +As in their crime. Thus was the applause they meant, +Turned to exploding hiss, triumph to shame +Cast on themselves from their own mouths. There stood +A grove hard by, sprung up with this their change, +His will who reigns above, to aggravate +Their penance, laden with fair fruit, like that +Which grew in Paradise, the bait of Eve +Used by the Tempter: on that prospect strange +Their earnest eyes they fixed, imagining +For one forbidden tree a multitude +Now risen, to work them further woe or shame; +Yet, parched with scalding thirst and hunger fierce, +Though to delude them sent, could not abstain; +But on they rolled in heaps, and, up the trees +Climbing, sat thicker than the snaky locks +That curled Megaera: greedily they plucked +The fruitage fair to sight, like that which grew +Near that bituminous lake where Sodom flamed; +This more delusive, not the touch, but taste +Deceived; they, fondly thinking to allay +Their appetite with gust, instead of fruit +Chewed bitter ashes, which the offended taste +With spattering noise rejected: oft they assayed, +Hunger and thirst constraining; drugged as oft, +With hatefullest disrelish writhed their jaws, +With soot and cinders filled; so oft they fell +Into the same illusion, not as Man +Whom they triumphed once lapsed. Thus were they plagued +And worn with famine, long and ceaseless hiss, +Till their lost shape, permitted, they resumed; +Yearly enjoined, some say, to undergo, +This annual humbling certain numbered days, +To dash their pride, and joy, for Man seduced. +However, some tradition they dispersed +Among the Heathen, of their purchase got, +And fabled how the Serpent, whom they called +Ophion, with Eurynome, the wide-- +Encroaching Eve perhaps, had first the rule +Of high Olympus; thence by Saturn driven +And Ops, ere yet Dictaean Jove was born. +Mean while in Paradise the hellish pair +Too soon arrived; Sin, there in power before, +Once actual; now in body, and to dwell +Habitual habitant; behind her Death, +Close following pace for pace, not mounted yet +On his pale horse: to whom Sin thus began. +Second of Satan sprung, all-conquering Death! +What thinkest thou of our empire now, though earned +With travel difficult, not better far +Than still at Hell's dark threshold to have sat watch, +Unnamed, undreaded, and thyself half starved? +Whom thus the Sin-born monster answered soon. +To me, who with eternal famine pine, +Alike is Hell, or Paradise, or Heaven; +There best, where most with ravine I may meet; +Which here, though plenteous, all too little seems +To stuff this maw, this vast unhide-bound corps. +To whom the incestuous mother thus replied. +Thou therefore on these herbs, and fruits, and flowers, +Feed first; on each beast next, and fish, and fowl; +No homely morsels! and, whatever thing +The sithe of Time mows down, devour unspared; +Till I, in Man residing, through the race, +His thoughts, his looks, words, actions, all infect; +And season him thy last and sweetest prey. +This said, they both betook them several ways, +Both to destroy, or unimmortal make +All kinds, and for destruction to mature +Sooner or later; which the Almighty seeing, +From his transcendent seat the Saints among, +To those bright Orders uttered thus his voice. +See, with what heat these dogs of Hell advance +To waste and havock yonder world, which I +So fair and good created; and had still +Kept in that state, had not the folly of Man +Let in these wasteful furies, who impute +Folly to me; so doth the Prince of Hell +And his adherents, that with so much ease +I suffer them to enter and possess +A place so heavenly; and, conniving, seem +To gratify my scornful enemies, +That laugh, as if, transported with some fit +Of passion, I to them had quitted all, +At random yielded up to their misrule; +And know not that I called, and drew them thither, +My Hell-hounds, to lick up the draff and filth +Which Man's polluting sin with taint hath shed +On what was pure; til, crammed and gorged, nigh burst +With sucked and glutted offal, at one sling +Of thy victorious arm, well-pleasing Son, +Both Sin, and Death, and yawning Grave, at last, +Through Chaos hurled, obstruct the mouth of Hell +For ever, and seal up his ravenous jaws. +Then Heaven and Earth renewed shall be made pure +To sanctity, that shall receive no stain: +Till then, the curse pronounced on both precedes. +He ended, and the heavenly audience loud +Sung Halleluiah, as the sound of seas, +Through multitude that sung: Just are thy ways, +Righteous are thy decrees on all thy works; +Who can extenuate thee? Next, to the Son, +Destined Restorer of mankind, by whom +New Heaven and Earth shall to the ages rise, +Or down from Heaven descend.--Such was their song; +While the Creator, calling forth by name +His mighty Angels, gave them several charge, +As sorted best with present things. The sun +Had first his precept so to move, so shine, +As might affect the earth with cold and heat +Scarce tolerable; and from the north to call +Decrepit winter; from the south to bring +Solstitial summer's heat. To the blanc moon +Her office they prescribed; to the other five +Their planetary motions, and aspects, +In sextile, square, and trine, and opposite, +Of noxious efficacy, and when to join +In synod unbenign; and taught the fixed +Their influence malignant when to shower, +Which of them rising with the sun, or falling, +Should prove tempestuous: To the winds they set +Their corners, when with bluster to confound +Sea, air, and shore; the thunder when to roll +With terrour through the dark aereal hall. +Some say, he bid his Angels turn ascanse +The poles of earth, twice ten degrees and more, +From the sun's axle; they with labour pushed +Oblique the centrick globe: Some say, the sun +Was bid turn reins from the equinoctial road +Like distant breadth to Taurus with the seven +Atlantick Sisters, and the Spartan Twins, +Up to the Tropick Crab: thence down amain +By Leo, and the Virgin, and the Scales, +As deep as Capricorn; to bring in change +Of seasons to each clime; else had the spring +Perpetual smiled on earth with vernant flowers, +Equal in days and nights, except to those +Beyond the polar circles; to them day +Had unbenighted shone, while the low sun, +To recompense his distance, in their sight +Had rounded still the horizon, and not known +Or east or west; which had forbid the snow +From cold Estotiland, and south as far +Beneath Magellan. At that tasted fruit +The sun, as from Thyestean banquet, turned +His course intended; else, how had the world +Inhabited, though sinless, more than now, +Avoided pinching cold and scorching heat? +These changes in the Heavens, though slow, produced +Like change on sea and land; sideral blast, +Vapour, and mist, and exhalation hot, +Corrupt and pestilent: Now from the north +Of Norumbega, and the Samoed shore, +Bursting their brazen dungeon, armed with ice, +And snow, and hail, and stormy gust and flaw, +Boreas, and Caecias, and Argestes loud, +And Thrascias, rend the woods, and seas upturn; +With adverse blast upturns them from the south +Notus, and Afer black with thunderous clouds +From Serraliona; thwart of these, as fierce, +Forth rush the Levant and the Ponent winds, +Eurus and Zephyr, with their lateral noise, +Sirocco and Libecchio. Thus began +Outrage from lifeless things; but Discord first, +Daughter of Sin, among the irrational +Death introduced, through fierce antipathy: +Beast now with beast 'gan war, and fowl with fowl, +And fish with fish; to graze the herb all leaving, +Devoured each other; nor stood much in awe +Of Man, but fled him; or, with countenance grim, +Glared on him passing. These were from without +The growing miseries, which Adam saw +Already in part, though hid in gloomiest shade, +To sorrow abandoned, but worse felt within; +And, in a troubled sea of passion tost, +Thus to disburden sought with sad complaint. +O miserable of happy! Is this the end +Of this new glorious world, and me so late +The glory of that glory, who now become +Accursed, of blessed? hide me from the face +Of God, whom to behold was then my highth +Of happiness!--Yet well, if here would end +The misery; I deserved it, and would bear +My own deservings; but this will not serve: +All that I eat or drink, or shall beget, +Is propagated curse. O voice, once heard +Delightfully, Encrease and multiply; +Now death to hear! for what can I encrease, +Or multiply, but curses on my head? +Who of all ages to succeed, but, feeling +The evil on him brought by me, will curse +My head? Ill fare our ancestor impure, +For this we may thank Adam! but his thanks +Shall be the execration: so, besides +Mine own that bide upon me, all from me +Shall with a fierce reflux on me rebound; +On me, as on their natural center, light +Heavy, though in their place. O fleeting joys +Of Paradise, dear bought with lasting woes! +Did I request thee, Maker, from my clay +To mould me Man? did I solicit thee +From darkness to promote me, or here place +In this delicious garden? As my will +Concurred not to my being, it were but right +And equal to reduce me to my dust; +Desirous to resign and render back +All I received; unable to perform +Thy terms too hard, by which I was to hold +The good I sought not. To the loss of that, +Sufficient penalty, why hast thou added +The sense of endless woes? Inexplicable +Why am I mocked with death, and lengthened out +To deathless pain? How gladly would I meet +Mortality my sentence, and be earth +Insensible! How glad would lay me down +As in my mother's lap! There I should rest, +And sleep secure; his dreadful voice no more +Would thunder in my ears; no fear of worse +To me, and to my offspring, would torment me +With cruel expectation. Yet one doubt +Pursues me still, lest all I cannot die; +Lest that pure breath of life, the spirit of Man +Which God inspired, cannot together perish +With this corporeal clod; then, in the grave, +Or in some other dismal place, who knows +But I shall die a living death? O thought +Horrid, if true! Yet why? It was but breath +Of life that sinned; what dies but what had life +And sin? The body properly had neither, +All of me then shall die: let this appease +The doubt, since human reach no further knows. +For though the Lord of all be infinite, +Is his wrath also? Be it, Man is not so, +But mortal doomed. How can he exercise +Wrath without end on Man, whom death must end? +Can he make deathless death? That were to make +Strange contradiction, which to God himself +Impossible is held; as argument +Of weakness, not of power. Will he draw out, +For anger's sake, finite to infinite, +In punished Man, to satisfy his rigour, +Satisfied never? That were to extend +His sentence beyond dust and Nature's law; +By which all causes else, according still +To the reception of their matter, act; +Not to the extent of their own sphere. But say +That death be not one stroke, as I supposed, +Bereaving sense, but endless misery +From this day onward; which I feel begun +Both in me, and without me; and so last +To perpetuity;--Ay me!that fear +Comes thundering back with dreadful revolution +On my defenceless head; both Death and I +Am found eternal, and incorporate both; +Nor I on my part single; in me all +Posterity stands cursed: Fair patrimony +That I must leave ye, Sons! O, were I able +To waste it all myself, and leave ye none! +So disinherited, how would you bless +Me, now your curse! Ah, why should all mankind, +For one man's fault, thus guiltless be condemned, +It guiltless? But from me what can proceed, +But all corrupt; both mind and will depraved +Not to do only, but to will the same +With me? How can they then acquitted stand +In sight of God? Him, after all disputes, +Forced I absolve: all my evasions vain, +And reasonings, though through mazes, lead me still +But to my own conviction: first and last +On me, me only, as the source and spring +Of all corruption, all the blame lights due; +So might the wrath! Fond wish!couldst thou support +That burden, heavier than the earth to bear; +Than all the world much heavier, though divided +With that bad Woman? Thus, what thou desirest, +And what thou fearest, alike destroys all hope +Of refuge, and concludes thee miserable +Beyond all past example and future; +To Satan only like both crime and doom. +O Conscience! into what abyss of fears +And horrours hast thou driven me; out of which +I find no way, from deep to deeper plunged! +Thus Adam to himself lamented loud, +Through the still night; not now, as ere Man fell, +Wholesome, and cool, and mild, but with black air +Accompanied; with damps, and dreadful gloom; +Which to his evil conscience represented +All things with double terrour: On the ground +Outstretched he lay, on the cold ground; and oft +Cursed his creation; Death as oft accused +Of tardy execution, since denounced +The day of his offence. Why comes not Death, +Said he, with one thrice-acceptable stroke +To end me? Shall Truth fail to keep her word, +Justice Divine not hasten to be just? +But Death comes not at call; Justice Divine +Mends not her slowest pace for prayers or cries, +O woods, O fountains, hillocks, dales, and bowers! +With other echo late I taught your shades +To answer, and resound far other song.-- +Whom thus afflicted when sad Eve beheld, +Desolate where she sat, approaching nigh, +Soft words to his fierce passion she assayed: +But her with stern regard he thus repelled. +Out of my sight, thou Serpent! That name best +Befits thee with him leagued, thyself as false +And hateful; nothing wants, but that thy shape, +Like his, and colour serpentine, may show +Thy inward fraud; to warn all creatures from thee +Henceforth; lest that too heavenly form, pretended +To hellish falshood, snare them! But for thee +I had persisted happy; had not thy pride +And wandering vanity, when least was safe, +Rejected my forewarning, and disdained +Not to be trusted; longing to be seen, +Though by the Devil himself; him overweening +To over-reach; but, with the serpent meeting, +Fooled and beguiled; by him thou, I by thee +To trust thee from my side; imagined wise, +Constant, mature, proof against all assaults; +And understood not all was but a show, +Rather than solid virtue; all but a rib +Crooked by nature, bent, as now appears, +More to the part sinister, from me drawn; +Well if thrown out, as supernumerary +To my just number found. O! why did God, +Creator wise, that peopled highest Heaven +With Spirits masculine, create at last +This novelty on earth, this fair defect +Of nature, and not fill the world at once +With Men, as Angels, without feminine; +Or find some other way to generate +Mankind? This mischief had not been befallen, +And more that shall befall; innumerable +Disturbances on earth through female snares, +And strait conjunction with this sex: for either +He never shall find out fit mate, but such +As some misfortune brings him, or mistake; +Or whom he wishes most shall seldom gain +Through her perverseness, but shall see her gained +By a far worse; or, if she love, withheld +By parents; or his happiest choice too late +Shall meet, already linked and wedlock-bound +To a fell adversary, his hate or shame: +Which infinite calamity shall cause +To human life, and houshold peace confound. +He added not, and from her turned; but Eve, +Not so repulsed, with tears that ceased not flowing +And tresses all disordered, at his feet +Fell humble; and, embracing them, besought +His peace, and thus proceeded in her plaint. +Forsake me not thus, Adam! witness Heaven +What love sincere, and reverence in my heart +I bear thee, and unweeting have offended, +Unhappily deceived! Thy suppliant +I beg, and clasp thy knees; bereave me not, +Whereon I live, thy gentle looks, thy aid, +Thy counsel, in this uttermost distress, +My only strength and stay: Forlorn of thee, +Whither shall I betake me, where subsist? +While yet we live, scarce one short hour perhaps, +Between us two let there be peace; both joining, +As joined in injuries, one enmity +Against a foe by doom express assigned us, +That cruel Serpent: On me exercise not +Thy hatred for this misery befallen; +On me already lost, me than thyself +More miserable! Both have sinned;but thou +Against God only; I against God and thee; +And to the place of judgement will return, +There with my cries importune Heaven; that all +The sentence, from thy head removed, may light +On me, sole cause to thee of all this woe; +Me, me only, just object of his ire! +She ended weeping; and her lowly plight, +Immoveable, till peace obtained from fault +Acknowledged and deplored, in Adam wrought +Commiseration: Soon his heart relented +Towards her, his life so late, and sole delight, +Now at his feet submissive in distress; +Creature so fair his reconcilement seeking, +His counsel, whom she had displeased, his aid: +As one disarmed, his anger all he lost, +And thus with peaceful words upraised her soon. +Unwary, and too desirous, as before, +So now of what thou knowest not, who desirest +The punishment all on thyself; alas! +Bear thine own first, ill able to sustain +His full wrath, whose thou feelest as yet least part, +And my displeasure bearest so ill. If prayers +Could alter high decrees, I to that place +Would speed before thee, and be louder heard, +That on my head all might be visited; +Thy frailty and infirmer sex forgiven, +To me committed, and by me exposed. +But rise;--let us no more contend, nor blame +Each other, blamed enough elsewhere; but strive +In offices of love, how we may lighten +Each other's burden, in our share of woe; +Since this day's death denounced, if aught I see, +Will prove no sudden, but a slow-paced evil; +A long day's dying, to augment our pain; +And to our seed (O hapless seed!) derived. +To whom thus Eve, recovering heart, replied. +Adam, by sad experiment I know +How little weight my words with thee can find, +Found so erroneous; thence by just event +Found so unfortunate: Nevertheless, +Restored by thee, vile as I am, to place +Of new acceptance, hopeful to regain +Thy love, the sole contentment of my heart +Living or dying, from thee I will not hide +What thoughts in my unquiet breast are risen, +Tending to some relief of our extremes, +Or end; though sharp and sad, yet tolerable, +As in our evils, and of easier choice. +If care of our descent perplex us most, +Which must be born to certain woe, devoured +By Death at last; and miserable it is +To be to others cause of misery, +Our own begotten, and of our loins to bring +Into this cursed world a woeful race, +That after wretched life must be at last +Food for so foul a monster; in thy power +It lies, yet ere conception to prevent +The race unblest, to being yet unbegot. +Childless thou art, childless remain: so Death +Shall be deceived his glut, and with us two +Be forced to satisfy his ravenous maw. +But if thou judge it hard and difficult, +Conversing, looking, loving, to abstain +From love's due rights, nuptial embraces sweet; +And with desire to languish without hope, +Before the present object languishing +With like desire; which would be misery +And torment less than none of what we dread; +Then, both ourselves and seed at once to free +From what we fear for both, let us make short, -- +Let us seek Death; -- or, he not found, supply +With our own hands his office on ourselves: +Why stand we longer shivering under fears, +That show no end but death, and have the power, +Of many ways to die the shortest choosing, +Destruction with destruction to destroy? -- +She ended here, or vehement despair +Broke off the rest: so much of death her thoughts +Had entertained, as dyed her cheeks with pale. +But Adam, with such counsel nothing swayed, +To better hopes his more attentive mind +Labouring had raised; and thus to Eve replied. +Eve, thy contempt of life and pleasure seems +To argue in thee something more sublime +And excellent, than what thy mind contemns; +But self-destruction therefore sought, refutes +That excellence thought in thee; and implies, +Not thy contempt, but anguish and regret +For loss of life and pleasure overloved. +Or if thou covet death, as utmost end +Of misery, so thinking to evade +The penalty pronounced; doubt not but God +Hath wiselier armed his vengeful ire, than so +To be forestalled; much more I fear lest death, +So snatched, will not exempt us from the pain +We are by doom to pay; rather, such acts +Of contumacy will provoke the Highest +To make death in us live: Then let us seek +Some safer resolution, which methinks +I have in view, calling to mind with heed +Part of our sentence, that thy seed shall bruise +The Serpent's head; piteous amends! unless +Be meant, whom I conjecture, our grand foe, +Satan; who, in the serpent, hath contrived +Against us this deceit: To crush his head +Would be revenge indeed! which will be lost +By death brought on ourselves, or childless days +Resolved, as thou proposest; so our foe +Shal 'scape his punishment ordained, and we +Instead shall double ours upon our heads. +No more be mentioned then of violence +Against ourselves; and wilful barrenness, +That cuts us off from hope; and savours only +Rancour and pride, impatience and despite, +Reluctance against God and his just yoke +Laid on our necks. Remember with what mild +And gracious temper he both heard, and judged, +Without wrath or reviling; we expected +Immediate dissolution, which we thought +Was meant by death that day; when lo!to thee +Pains only in child-bearing were foretold, +And bringing forth; soon recompensed with joy, +Fruit of thy womb: On me the curse aslope +Glanced on the ground; with labour I must earn +My bread; what harm? Idleness had been worse; +My labour will sustain me; and, lest cold +Or heat should injure us, his timely care +Hath, unbesought, provided; and his hands +Clothed us unworthy, pitying while he judged; +How much more, if we pray him, will his ear +Be open, and his heart to pity incline, +And teach us further by what means to shun +The inclement seasons, rain, ice, hail, and snow! +Which now the sky, with various face, begins +To show us in this mountain; while the winds +Blow moist and keen, shattering the graceful locks +Of these fair spreading trees; which bids us seek +Some better shroud, some better warmth to cherish +Our limbs benummed, ere this diurnal star +Leave cold the night, how we his gathered beams +Reflected may with matter sere foment; +Or, by collision of two bodies, grind +The air attrite to fire; as late the clouds +Justling, or pushed with winds, rude in their shock, +Tine the slant lightning; whose thwart flame, driven down +Kindles the gummy bark of fir or pine; +And sends a comfortable heat from far, +Which might supply the sun: Such fire to use, +And what may else be remedy or cure +To evils which our own misdeeds have wrought, +He will instruct us praying, and of grace +Beseeching him; so as we need not fear +To pass commodiously this life, sustained +By him with many comforts, till we end +In dust, our final rest and native home. +What better can we do, than, to the place +Repairing where he judged us, prostrate fall +Before him reverent; and there confess +Humbly our faults, and pardon beg; with tears +Watering the ground, and with our sighs the air +Frequenting, sent from hearts contrite, in sign +Of sorrow unfeigned, and humiliation meek + + + +Book XI + + +Undoubtedly he will relent, and turn +From his displeasure; in whose look serene, +When angry most he seemed and most severe, +What else but favour, grace, and mercy, shone? +So spake our father penitent; nor Eve +Felt less remorse: they, forthwith to the place +Repairing where he judged them, prostrate fell +Before him reverent; and both confessed +Humbly their faults, and pardon begged; with tears +Watering the ground, and with their sighs the air +Frequenting, sent from hearts contrite, in sign +Of sorrow unfeigned, and humiliation meek. +Thus they, in lowliest plight, repentant stood +Praying; for from the mercy-seat above +Prevenient grace descending had removed +The stony from their hearts, and made new flesh +Regenerate grow instead; that sighs now breathed +Unutterable; which the Spirit of prayer +Inspired, and winged for Heaven with speedier flight +Than loudest oratory: Yet their port +Not of mean suitors; nor important less +Seemed their petition, than when the ancient pair +In fables old, less ancient yet than these, +Deucalion and chaste Pyrrha, to restore +The race of mankind drowned, before the shrine +Of Themis stood devout. To Heaven their prayers +Flew up, nor missed the way, by envious winds +Blown vagabond or frustrate: in they passed +Dimensionless through heavenly doors; then clad +With incense, where the golden altar fumed, +By their great intercessour, came in sight +Before the Father's throne: them the glad Son +Presenting, thus to intercede began. +See$ Father, what first-fruits on earth are sprung +From thy implanted grace in Man; these sighs +And prayers, which in this golden censer mixed +With incense, I thy priest before thee bring; +Fruits of more pleasing savour, from thy seed +Sown with contrition in his heart, than those +Which, his own hand manuring, all the trees +Of Paradise could have produced, ere fallen +From innocence. Now therefore, bend thine ear +To supplication; hear his sighs, though mute; +Unskilful with what words to pray, let me +Interpret for him; me, his advocate +And propitiation; all his works on me, +Good, or not good, ingraft; my merit those +Shall perfect, and for these my death shall pay. +Accept me; and, in me, from these receive +The smell of peace toward mankind: let him live +Before thee reconciled, at least his days +Numbered, though sad; till death, his doom, (which I +To mitigate thus plead, not to reverse,) +To better life shall yield him: where with me +All my redeemed may dwell in joy and bliss; +Made one with me, as I with thee am one. +To whom the Father, without cloud, serene. +All thy request for Man, accepted Son, +Obtain; all thy request was my decree: +But, longer in that Paradise to dwell, +The law I gave to Nature him forbids: +Those pure immortal elements, that know, +No gross, no unharmonious mixture foul, +Eject him, tainted now; and purge him off, +As a distemper, gross, to air as gross, +And mortal food; as may dispose him best +For dissolution wrought by sin, that first +Distempered all things, and of incorrupt +Corrupted. I, at first, with two fair gifts +Created him endowed; with happiness, +And immortality: that fondly lost, +This other served but to eternize woe; +Till I provided death: so death becomes +His final remedy; and, after life, +Tried in sharp tribulation, and refined +By faith and faithful works, to second life, +Waked in the renovation of the just, +Resigns him up with Heaven and Earth renewed. +But let us call to synod all the Blest, +Through Heaven's wide bounds: from them I will not hide +My judgements; how with mankind I proceed, +As how with peccant Angels late they saw, +And in their state, though firm, stood more confirmed. +He ended, and the Son gave signal high +To the bright minister that watched; he blew +His trumpet, heard in Oreb since perhaps +When God descended, and perhaps once more +To sound at general doom. The angelick blast +Filled all the regions: from their blisful bowers +Of amarantine shade, fountain or spring, +By the waters of life, where'er they sat +In fellowships of joy, the sons of light +Hasted, resorting to the summons high; +And took their seats; till from his throne supreme +The Almighty thus pronounced his sovran will. +O Sons, like one of us Man is become +To know both good and evil, since his taste +Of that defended fruit; but let him boast +His knowledge of good lost, and evil got; +Happier! had it sufficed him to have known +Good by itself, and evil not at all. +He sorrows now, repents, and prays contrite, +My motions in him; longer than they move, +His heart I know, how variable and vain, +Self-left. Lest therefore his now bolder hand +Reach also of the tree of life, and eat, +And live for ever, dream at least to live +For ever, to remove him I decree, +And send him from the garden forth to till +The ground whence he was taken, fitter soil. +Michael, this my behest have thou in charge; +Take to thee from among the Cherubim +Thy choice of flaming warriours, lest the Fiend, +Or in behalf of Man, or to invade +Vacant possession, some new trouble raise: +Haste thee, and from the Paradise of God +Without remorse drive out the sinful pair; +From hallowed ground the unholy; and denounce +To them, and to their progeny, from thence +Perpetual banishment. Yet, lest they faint +At the sad sentence rigorously urged, +(For I behold them softened, and with tears +Bewailing their excess,) all terrour hide. +If patiently thy bidding they obey, +Dismiss them not disconsolate; reveal +To Adam what shall come in future days, +As I shall thee enlighten; intermix +My covenant in the Woman's seed renewed; +So send them forth, though sorrowing, yet in peace: +And on the east side of the garden place, +Where entrance up from Eden easiest climbs, +Cherubick watch; and of a sword the flame +Wide-waving; all approach far off to fright, +And guard all passage to the tree of life: +Lest Paradise a receptacle prove +To Spirits foul, and all my trees their prey; +With whose stolen fruit Man once more to delude. +He ceased; and the arch-angelick Power prepared +For swift descent; with him the cohort bright +Of watchful Cherubim: four faces each +Had, like a double Janus; all their shape +Spangled with eyes more numerous than those +Of Argus, and more wakeful than to drouse, +Charmed with Arcadian pipe, the pastoral reed +Of Hermes, or his opiate rod. Mean while, +To re-salute the world with sacred light, +Leucothea waked; and with fresh dews imbalmed +The earth; when Adam and first matron Eve +Had ended now their orisons, and found +Strength added from above; new hope to spring +Out of despair; joy, but with fear yet linked; +Which thus to Eve his welcome words renewed. +Eve, easily my faith admit, that all +The good which we enjoy from Heaven descends; +But, that from us aught should ascend to Heaven +So prevalent as to concern the mind +Of God high-blest, or to incline his will, +Hard to belief may seem; yet this will prayer +Or one short sigh of human breath, upborne +Even to the seat of God. For since I sought +By prayer the offended Deity to appease; +Kneeled, and before him humbled all my heart; +Methought I saw him placable and mild, +Bending his ear; persuasion in me grew +That I was heard with favour; peace returned +Home to my breast, and to my memory +His promise, that thy seed shall bruise our foe; +Which, then not minded in dismay, yet now +Assures me that the bitterness of death +Is past, and we shall live. Whence hail to thee, +Eve rightly called, mother of all mankind, +Mother of all things living, since by thee +Man is to live; and all things live for Man. +To whom thus Eve with sad demeanour meek. +Ill-worthy I such title should belong +To me transgressour; who, for thee ordained +A help, became thy snare; to me reproach +Rather belongs, distrust, and all dispraise: +But infinite in pardon was my Judge, +That I, who first brought death on all, am graced +The source of life; next favourable thou, +Who highly thus to entitle me vouchsaf'st, +Far other name deserving. But the field +To labour calls us, now with sweat imposed, +Though after sleepless night; for see!the morn, +All unconcerned with our unrest, begins +Her rosy progress smiling: let us forth; +I never from thy side henceforth to stray, +Where'er our day's work lies, though now enjoined +Laborious, till day droop; while here we dwell, +What can be toilsome in these pleasant walks? +Here let us live, though in fallen state, content. +So spake, so wished much humbled Eve; but Fate +Subscribed not: Nature first gave signs, impressed +On bird, beast, air; air suddenly eclipsed, +After short blush of morn; nigh in her sight +The bird of Jove, stooped from his aery tour, +Two birds of gayest plume before him drove; +Down from a hill the beast that reigns in woods, +First hunter then, pursued a gentle brace, +Goodliest of all the forest, hart and hind; +Direct to the eastern gate was bent their flight. +Adam observed, and with his eye the chase +Pursuing, not unmoved, to Eve thus spake. +O Eve, some further change awaits us nigh, +Which Heaven, by these mute signs in Nature, shows +Forerunners of his purpose; or to warn +Us, haply too secure, of our discharge +From penalty, because from death released +Some days: how long, and what till then our life, +Who knows? or more than this, that we are dust, +And thither must return, and be no more? +Why else this double object in our sight +Of flight pursued in the air, and o'er the ground, +One way the self-same hour? why in the east +Darkness ere day's mid-course, and morning-light +More orient in yon western cloud, that draws +O'er the blue firmament a radiant white, +And slow descends with something heavenly fraught? +He erred not; for by this the heavenly bands +Down from a sky of jasper lighted now +In Paradise, and on a hill made halt; +A glorious apparition, had not doubt +And carnal fear that day dimmed Adam's eye. +Not that more glorious, when the Angels met +Jacob in Mahanaim, where he saw +The field pavilioned with his guardians bright; +Nor that, which on the flaming mount appeared +In Dothan, covered with a camp of fire, +Against the Syrian king, who to surprise +One man, assassin-like, had levied war, +War unproclaimed. The princely Hierarch +In their bright stand there left his Powers, to seise +Possession of the garden; he alone, +To find where Adam sheltered, took his way, +Not unperceived of Adam; who to Eve, +While the great visitant approached, thus spake. +Eve$ now expect great tidings, which perhaps +Of us will soon determine, or impose +New laws to be observed; for I descry, +From yonder blazing cloud that veils the hill, +One of the heavenly host; and, by his gait, +None of the meanest; some great Potentate +Or of the Thrones above; such majesty +Invests him coming! yet not terrible, +That I should fear; nor sociably mild, +As Raphael, that I should much confide; +But solemn and sublime; whom not to offend, +With reverence I must meet, and thou retire. +He ended: and the Arch-Angel soon drew nigh, +Not in his shape celestial, but as man +Clad to meet man; over his lucid arms +A military vest of purple flowed, +Livelier than Meliboean, or the grain +Of Sarra, worn by kings and heroes old +In time of truce; Iris had dipt the woof; +His starry helm unbuckled showed him prime +In manhood where youth ended; by his side, +As in a glistering zodiack, hung the sword, +Satan's dire dread; and in his hand the spear. +Adam bowed low; he, kingly, from his state +Inclined not, but his coming thus declared. +Adam, Heaven's high behest no preface needs: +Sufficient that thy prayers are heard; and Death, +Then due by sentence when thou didst transgress, +Defeated of his seisure many days +Given thee of grace; wherein thou mayest repent, +And one bad act with many deeds well done +Mayest cover: Well may then thy Lord, appeased, +Redeem thee quite from Death's rapacious claim; +But longer in this Paradise to dwell +Permits not: to remove thee I am come, +And send thee from the garden forth to till +The ground whence thou wast taken, fitter soil. +He added not; for Adam at the news +Heart-struck with chilling gripe of sorrow stood, +That all his senses bound; Eve, who unseen +Yet all had heard, with audible lament +Discovered soon the place of her retire. +O unexpected stroke, worse than of Death! +Must I thus leave thee$ Paradise? thus leave +Thee, native soil! these happy walks and shades, +Fit haunt of Gods? where I had hope to spend, +Quiet though sad, the respite of that day +That must be mortal to us both. O flowers, +That never will in other climate grow, +My early visitation, and my last + ;t even, which I bred up with tender hand +From the first opening bud, and gave ye names! +Who now shall rear ye to the sun, or rank +Your tribes, and water from the ambrosial fount? +Thee lastly, nuptial bower! by me adorned +With what to sight or smell was sweet! from thee +How shall I part, and whither wander down +Into a lower world; to this obscure +And wild? how shall we breathe in other air +Less pure, accustomed to immortal fruits? +Whom thus the Angel interrupted mild. +Lament not, Eve, but patiently resign +What justly thou hast lost, nor set thy heart, +Thus over-fond, on that which is not thine: +Thy going is not lonely; with thee goes +Thy husband; whom to follow thou art bound; +Where he abides, think there thy native soil. +Adam, by this from the cold sudden damp +Recovering, and his scattered spirits returned, +To Michael thus his humble words addressed. +Celestial, whether among the Thrones, or named +Of them the highest; for such of shape may seem +Prince above princes! gently hast thou told +Thy message, which might else in telling wound, +And in performing end us; what besides +Of sorrow, and dejection, and despair, +Our frailty can sustain, thy tidings bring, +Departure from this happy place, our sweet +Recess, and only consolation left +Familiar to our eyes! all places else +Inhospitable appear, and desolate; +Nor knowing us, nor known: And, if by prayer +Incessant I could hope to change the will +Of Him who all things can, I would not cease +To weary him with my assiduous cries: +But prayer against his absolute decree +No more avails than breath against the wind, +Blown stifling back on him that breathes it forth: +Therefore to his great bidding I submit. +This most afflicts me, that, departing hence, +As from his face I shall be hid, deprived +His blessed countenance: Here I could frequent +With worship place by place where he vouchsafed +Presence Divine; and to my sons relate, +'On this mount he appeared; under this tree +'Stood visible; among these pines his voice +'I heard; here with him at this fountain talked: +So many grateful altars I would rear +Of grassy turf, and pile up every stone +Of lustre from the brook, in memory, +Or monument to ages; and theron +Offer sweet-smelling gums, and fruits, and flowers: +In yonder nether world where shall I seek +His bright appearances, or foot-step trace? +For though I fled him angry, yet recalled +To life prolonged and promised race, I now +Gladly behold though but his utmost skirts +Of glory; and far off his steps adore. +To whom thus Michael with regard benign. +Adam, thou knowest Heaven his, and all the Earth; +Not this rock only; his Omnipresence fills +Land, sea, and air, and every kind that lives, +Fomented by his virtual power and warmed: +All the earth he gave thee to possess and rule, +No despicable gift; surmise not then +His presence to these narrow bounds confined +Of Paradise, or Eden: this had been +Perhaps thy capital seat, from whence had spread +All generations; and had hither come +From all the ends of the earth, to celebrate +And reverence thee, their great progenitor. +But this pre-eminence thou hast lost, brought down +To dwell on even ground now with thy sons: +Yet doubt not but in valley, and in plain, +God is, as here; and will be found alike +Present; and of his presence many a sign +Still following thee, still compassing thee round +With goodness and paternal love, his face +Express, and of his steps the track divine. +Which that thou mayest believe, and be confirmed +Ere thou from hence depart; know, I am sent +To show thee what shall come in future days +To thee, and to thy offspring: good with bad +Expect to hear; supernal grace contending +With sinfulness of men; thereby to learn +True patience, and to temper joy with fear +And pious sorrow; equally inured +By moderation either state to bear, +Prosperous or adverse: so shalt thou lead +Safest thy life, and best prepared endure +Thy mortal passage when it comes.--Ascend +This hill; let Eve (for I have drenched her eyes) +Here sleep below; while thou to foresight wakest; +As once thou sleptst, while she to life was formed. +To whom thus Adam gratefully replied. +Ascend, I follow thee, safe Guide, the path +Thou leadest me; and to the hand of Heaven submit, +However chastening; to the evil turn +My obvious breast; arming to overcome +By suffering, and earn rest from labour won, +If so I may attain. -- So both ascend +In the visions of God. It was a hill, +Of Paradise the highest; from whose top +The hemisphere of earth, in clearest ken, +Stretched out to the amplest reach of prospect lay. +Not higher that hill, nor wider looking round, +Whereon, for different cause, the Tempter set +Our second Adam, in the wilderness; +To show him all Earth's kingdoms, and their glory. +His eye might there command wherever stood +City of old or modern fame, the seat +Of mightiest empire, from the destined walls +Of Cambalu, seat of Cathaian Can, +And Samarchand by Oxus, Temir's throne, +To Paquin of Sinaean kings; and thence +To Agra and Lahor of great Mogul, +Down to the golden Chersonese; or where +The Persian in Ecbatan sat, or since +In Hispahan; or where the Russian Ksar +In Mosco; or the Sultan in Bizance, +Turchestan-born; nor could his eye not ken +The empire of Negus to his utmost port +Ercoco, and the less maritim kings +Mombaza, and Quiloa, and Melind, +And Sofala, thought Ophir, to the realm +Of Congo, and Angola farthest south; +Or thence from Niger flood to Atlas mount +The kingdoms of Almansor, Fez and Sus, +Morocco, and Algiers, and Tremisen; +On Europe thence, and where Rome was to sway +The world: in spirit perhaps he also saw +Rich Mexico, the seat of Montezume, +And Cusco in Peru, the richer seat +Of Atabalipa; and yet unspoiled +Guiana, whose great city Geryon's sons +Call El Dorado. But to nobler sights +Michael from Adam's eyes the film removed, +Which that false fruit that promised clearer sight +Had bred; then purged with euphrasy and rue +The visual nerve, for he had much to see; +And from the well of life three drops instilled. +So deep the power of these ingredients pierced, +Even to the inmost seat of mental sight, +That Adam, now enforced to close his eyes, +Sunk down, and all his spirits became entranced; +But him the gentle Angel by the hand +Soon raised, and his attention thus recalled. +Adam, now ope thine eyes; and first behold +The effects, which thy original crime hath wrought +In some to spring from thee; who never touched +The excepted tree; nor with the snake conspired; +Nor sinned thy sin; yet from that sin derive +Corruption, to bring forth more violent deeds. +His eyes he opened, and beheld a field, +Part arable and tilth, whereon were sheaves +New reaped; the other part sheep-walks and folds; +I' the midst an altar as the land-mark stood, +Rustick, of grassy sord; thither anon +A sweaty reaper from his tillage brought +First fruits, the green ear, and the yellow sheaf, +Unculled, as came to hand; a shepherd next, +More meek, came with the firstlings of his flock, +Choicest and best; then, sacrificing, laid +The inwards and their fat, with incense strowed, +On the cleft wood, and all due rights performed: +His offering soon propitious fire from Heaven +Consumed with nimble glance, and grateful steam; +The other's not, for his was not sincere; +Whereat he inly raged, and, as they talked, +Smote him into the midriff with a stone +That beat out life; he fell;and, deadly pale, +Groaned out his soul with gushing blood effused. +Much at that sight was Adam in his heart +Dismayed, and thus in haste to the Angel cried. +O Teacher, some great mischief hath befallen +To that meek man, who well had sacrificed; +Is piety thus and pure devotion paid? +To whom Michael thus, he also moved, replied. +These two are brethren, Adam, and to come +Out of thy loins; the unjust the just hath slain, +For envy that his brother's offering found +From Heaven acceptance; but the bloody fact +Will be avenged; and the other's faith, approved, +Lose no reward; though here thou see him die, +Rolling in dust and gore. To which our sire. +Alas! both for the deed, and for the cause! +But have I now seen Death? Is this the way +I must return to native dust? O sight +Of terrour, foul and ugly to behold, +Horrid to think, how horrible to feel! +To whom thus Michael. Death thou hast seen +In his first shape on Man; but many shapes +Of Death, and many are the ways that lead +To his grim cave, all dismal; yet to sense +More terrible at the entrance, than within. +Some, as thou sawest, by violent stroke shall die; +By fire, flood, famine, by intemperance more +In meats and drinks, which on the earth shall bring +Diseases dire, of which a monstrous crew +Before thee shall appear; that thou mayest know +What misery the inabstinence of Eve +Shall bring on Men. Immediately a place +Before his eyes appeared, sad, noisome, dark; +A lazar-house it seemed; wherein were laid +Numbers of all diseased; all maladies +Of ghastly spasm, or racking torture, qualms +Of heart-sick agony, all feverous kinds, +Convulsions, epilepsies, fierce catarrhs, +Intestine stone and ulcer, colick-pangs, +Demoniack phrenzy, moaping melancholy, +And moon-struck madness, pining atrophy, +Marasmus, and wide-wasting pestilence, +Dropsies, and asthmas, and joint-racking rheums. +Dire was the tossing, deep the groans; Despair +Tended the sick busiest from couch to couch; +And over them triumphant Death his dart +Shook, but delayed to strike, though oft invoked +With vows, as their chief good, and final hope. +Sight so deform what heart of rock could long +Dry-eyed behold? Adam could not, but wept, +Though not of woman born; compassion quelled +His best of man, and gave him up to tears +A space, till firmer thoughts restrained excess; +And, scarce recovering words, his plaint renewed. +O miserable mankind, to what fall +Degraded, to what wretched state reserved! +Better end here unborn. Why is life given +To be thus wrested from us? rather, why +Obtruded on us thus? who, if we knew +What we receive, would either no accept +Life offered, or soon beg to lay it down; +Glad to be so dismissed in peace. Can thus +The image of God in Man, created once +So goodly and erect, though faulty since, +To such unsightly sufferings be debased +Under inhuman pains? Why should not Man, +Retaining still divine similitude +In part, from such deformities be free, +And, for his Maker's image sake, exempt? +Their Maker's image, answered Michael, then +Forsook them, when themselves they vilified +To serve ungoverned Appetite; and took +His image whom they served, a brutish vice, +Inductive mainly to the sin of Eve. +Therefore so abject is their punishment, +Disfiguring not God's likeness, but their own; +Or if his likeness, by themselves defaced; +While they pervert pure Nature's healthful rules +To loathsome sickness; worthily, since they +God's image did not reverence in themselves. +I yield it just, said Adam, and submit. +But is there yet no other way, besides +These painful passages, how we may come +To death, and mix with our connatural dust? +There is, said Michael, if thou well observe +The rule of Not too much; by temperance taught, +In what thou eatest and drinkest; seeking from thence +Due nourishment, not gluttonous delight, +Till many years over thy head return: +So mayest thou live; till, like ripe fruit, thou drop +Into thy mother's lap; or be with ease +Gathered, nor harshly plucked; for death mature: +This is Old Age; but then, thou must outlive +Thy youth, thy strength, thy beauty; which will change +To withered, weak, and gray; thy senses then, +Obtuse, all taste of pleasure must forego, +To what thou hast; and, for the air of youth, +Hopeful and cheerful, in thy blood will reign +A melancholy damp of cold and dry +To weigh thy spirits down, and last consume +The balm of life. To whom our ancestor. +Henceforth I fly not death, nor would prolong +Life much; bent rather, how I may be quit, +Fairest and easiest, of this cumbrous charge; +Which I must keep till my appointed day +Of rendering up, and patiently attend +My dissolution. Michael replied. +Nor love thy life, nor hate; but what thou livest +Live well; how long, or short, permit to Heaven: +And now prepare thee for another sight. +He looked, and saw a spacious plain, whereon +Were tents of various hue; by some, were herds +Of cattle grazing; others, whence the sound +Of instruments, that made melodious chime, +Was heard, of harp and organ; and, who moved +Their stops and chords, was seen; his volant touch, +Instinct through all proportions, low and high, +Fled and pursued transverse the resonant fugue. +In other part stood one who, at the forge +Labouring, two massy clods of iron and brass +Had melted, (whether found where casual fire +Had wasted woods on mountain or in vale, +Down to the veins of earth; thence gliding hot +To some cave's mouth; or whether washed by stream +From underground;) the liquid ore he drained +Into fit moulds prepared; from which he formed +First his own tools; then, what might else be wrought +Fusil or graven in metal. After these, +But on the hither side, a different sort +From the high neighbouring hills, which was their seat, +Down to the plain descended; by their guise +Just men they seemed, and all their study bent +To worship God aright, and know his works +Not hid; nor those things last, which might preserve +Freedom and peace to Men; they on the plain +Long had not walked, when from the tents, behold! +A bevy of fair women, richly gay +In gems and wanton dress; to the harp they sung +Soft amorous ditties, and in dance came on: +The men, though grave, eyed them; and let their eyes +Rove without rein; till, in the amorous net +Fast caught, they liked; and each his liking chose; +And now of love they treat, till the evening-star, +Love's harbinger, appeared; then, all in heat +They light the nuptial torch, and bid invoke +Hymen, then first to marriage rites invoked: +With feast and musick all the tents resound. +Such happy interview, and fair event +Of love and youth not lost, songs, garlands, flowers, +And charming symphonies, attached the heart +Of Adam, soon inclined to admit delight, +The bent of nature; which he thus expressed. +True opener of mine eyes, prime Angel blest; +Much better seems this vision, and more hope +Of peaceful days portends, than those two past; +Those were of hate and death, or pain much worse; +Here Nature seems fulfilled in all her ends. +To whom thus Michael. Judge not what is best +By pleasure, though to nature seeming meet; +Created, as thou art, to nobler end +Holy and pure, conformity divine. +Those tents thou sawest so pleasant, were the tents +Of wickedness, wherein shall dwell his race +Who slew his brother; studious they appear +Of arts that polish life, inventers rare; +Unmindful of their Maker, though his Spirit +Taught them; but they his gifts acknowledged none. +Yet they a beauteous offspring shall beget; +For that fair female troop thou sawest, that seemed +Of Goddesses, so blithe, so smooth, so gay, +Yet empty of all good wherein consists +Woman's domestick honour and chief praise; +Bred only and completed to the taste +Of lustful appetence, to sing, to dance, +To dress, and troll the tongue, and roll the eye: +To these that sober race of men, whose lives +Religious titled them the sons of God, +Shall yield up all their virtue, all their fame +Ignobly, to the trains and to the smiles +Of these fair atheists; and now swim in joy, +Erelong to swim at large; and laugh, for which +The world erelong a world of tears must weep. +To whom thus Adam, of short joy bereft. +O pity and shame, that they, who to live well +Entered so fair, should turn aside to tread +Paths indirect, or in the mid way faint! +But still I see the tenour of Man's woe +Holds on the same, from Woman to begin. +From Man's effeminate slackness it begins, +Said the Angel, who should better hold his place +By wisdom, and superiour gifts received. +But now prepare thee for another scene. +He looked, and saw wide territory spread +Before him, towns, and rural works between; +Cities of men with lofty gates and towers, +Concourse in arms, fierce faces threatening war, +Giants of mighty bone and bold emprise; +Part wield their arms, part curb the foaming steed, +Single or in array of battle ranged +Both horse and foot, nor idly mustering stood; +One way a band select from forage drives +A herd of beeves, fair oxen and fair kine, +From a fat meadow ground; or fleecy flock, +Ewes and their bleating lambs over the plain, +Their booty; scarce with life the shepherds fly, +But call in aid, which makes a bloody fray; +With cruel tournament the squadrons join; +Where cattle pastured late, now scattered lies +With carcasses and arms the ensanguined field, +Deserted: Others to a city strong +Lay siege, encamped; by battery, scale, and mine, +Assaulting; others from the wall defend +With dart and javelin, stones, and sulphurous fire; +On each hand slaughter, and gigantick deeds. +In other part the sceptered heralds call +To council, in the city-gates; anon +Gray-headed men and grave, with warriours mixed, +Assemble, and harangues are heard; but soon, +In factious opposition; till at last, +Of middle age one rising, eminent +In wise deport, spake much of right and wrong, +Of justice, or religion, truth, and peace, +And judgement from above: him old and young +Exploded, and had seized with violent hands, +Had not a cloud descending snatched him thence +Unseen amid the throng: so violence +Proceeded, and oppression, and sword-law, +Through all the plain, and refuge none was found. +Adam was all in tears, and to his guide +Lamenting turned full sad; O!what are these, +Death's ministers, not men? who thus deal death +Inhumanly to men, and multiply +Ten thousandfold the sin of him who slew +His brother: for of whom such massacre +Make they, but of their brethren; men of men +But who was that just man, whom had not Heaven +Rescued, had in his righteousness been lost? +To whom thus Michael. These are the product +Of those ill-mated marriages thou sawest; +Where good with bad were matched, who of themselves +Abhor to join; and, by imprudence mixed, +Produce prodigious births of body or mind. +Such were these giants, men of high renown; +For in those days might only shall be admired, +And valour and heroick virtue called; +To overcome in battle, and subdue +Nations, and bring home spoils with infinite +Man-slaughter, shall be held the highest pitch +Of human glory; and for glory done +Of triumph, to be styled great conquerours +Patrons of mankind, Gods, and sons of Gods; +Destroyers rightlier called, and plagues of men. +Thus fame shall be achieved, renown on earth; +And what most merits fame, in silence hid. +But he, the seventh from thee, whom thou beheldst +The only righteous in a world preverse, +And therefore hated, therefore so beset +With foes, for daring single to be just, +And utter odious truth, that God would come +To judge them with his Saints; him the Most High +Rapt in a balmy cloud with winged steeds +Did, as thou sawest, receive, to walk with God +High in salvation and the climes of bliss, +Exempt from death; to show thee what reward +Awaits the good; the rest what punishment; +Which now direct thine eyes and soon behold. +He looked, and saw the face of things quite changed; +The brazen throat of war had ceased to roar; +All now was turned to jollity and game, +To luxury and riot, feast and dance; +Marrying or prostituting, as befel, +Rape or adultery, where passing fair +Allured them; thence from cups to civil broils. +At length a reverend sire among them came, +And of their doings great dislike declared, +And testified against their ways; he oft +Frequented their assemblies, whereso met, +Triumphs or festivals; and to them preached +Conversion and repentance, as to souls +In prison, under judgements imminent: +But all in vain: which when he saw, he ceased +Contending, and removed his tents far off; +Then, from the mountain hewing timber tall, +Began to build a vessel of huge bulk; +Measured by cubit, length, and breadth, and highth; +Smeared round with pitch; and in the side a door +Contrived; and of provisions laid in large, +For man and beast: when lo, a wonder strange! +Of every beast, and bird, and insect small, +Came sevens, and pairs; and entered in as taught +Their order: last the sire and his three sons, +With their four wives; and God made fast the door. +Mean while the south-wind rose, and, with black wings +Wide-hovering, all the clouds together drove +From under Heaven; the hills to their supply +Vapour, and exhalation dusk and moist, +Sent up amain; and now the thickened sky +Like a dark cieling stood; down rushed the rain +Impetuous; and continued, till the earth +No more was seen: the floating vessel swum +Uplifted, and secure with beaked prow +Rode tilting o'er the waves; all dwellings else +Flood overwhelmed, and them with all their pomp +Deep under water rolled; sea covered sea, +Sea without shore; and in their palaces, +Where luxury late reigned, sea-monsters whelped +And stabled; of mankind, so numerous late, +All left, in one small bottom swum imbarked. +How didst thou grieve then, Adam, to behold +The end of all thy offspring, end so sad, +Depopulation! Thee another flood, +Of tears and sorrow a flood, thee also drowned, +And sunk thee as thy sons; till, gently reared +By the Angel, on thy feet thou stoodest at last, +Though comfortless; as when a father mourns +His children, all in view destroyed at once; +And scarce to the Angel utter'dst thus thy plaint. +O visions ill foreseen! Better had I +Lived ignorant of future! so had borne +My part of evil only, each day's lot +Enough to bear; those now, that were dispensed +The burden of many ages, on me light +At once, by my foreknowledge gaining birth +Abortive, to torment me ere their being, +With thought that they must be. Let no man seek +Henceforth to be foretold, what shall befall +Him or his children; evil he may be sure, +Which neither his foreknowing can prevent; +And he the future evil shall no less +In apprehension than in substance feel, +Grievous to bear: but that care now is past, +Man is not whom to warn: those few escaped +Famine and anguish will at last consume, +Wandering that watery desart: I had hope, +When violence was ceased, and war on earth, +All would have then gone well; peace would have crowned +With length of happy days the race of Man; +But I was far deceived; for now I see +Peace to corrupt no less than war to waste. +How comes it thus? unfold, celestial Guide, +And whether here the race of Man will end. +To whom thus Michael. Those, whom last thou sawest +In triumph and luxurious wealth, are they +First seen in acts of prowess eminent +And great exploits, but of true virtue void; +Who, having spilt much blood, and done much wast +Subduing nations, and achieved thereby +Fame in the world, high titles, and rich prey; +Shall change their course to pleasure, ease, and sloth, +Surfeit, and lust; till wantonness and pride +Raise out of friendship hostile deeds in peace. +The conquered also, and enslaved by war, +Shall, with their freedom lost, all virtue lose +And fear of God; from whom their piety feigned +In sharp contest of battle found no aid +Against invaders; therefore, cooled in zeal, +Thenceforth shall practice how to live secure, +Worldly or dissolute, on what their lords +Shall leave them to enjoy; for the earth shall bear +More than enough, that temperance may be tried: +So all shall turn degenerate, all depraved; +Justice and temperance, truth and faith, forgot; +One man except, the only son of light +In a dark age, against example good, +Against allurement, custom, and a world +Offended: fearless of reproach and scorn, +The grand-child, with twelve sons encreased, departs +From Canaan, to a land hereafter called +Egypt, divided by the river Nile; +See where it flows, disgorging at seven mouths +Into the sea: To sojourn in that land +He comes, invited by a younger son +In time of dearth; a son, whose worthy deeds +Raise him to be the second in that realm +Of Pharaoh: There he dies, and leaves his race +Growing into a nation, and now grown +Suspected to a sequent king, who seeks +To stop their overgrowth, as inmate guests +Or violence, he of their wicked ways +Shall them admonish; and before them set +The paths of righteousness, how much more safe +And full of peace; denouncing wrath to come +On their impenitence; and shall return +Of them derided, but of God observed +The one just man alive; by his command +Shall build a wonderous ark, as thou beheldst, +To save himself, and houshold, from amidst +A world devote to universal wrack. +No sooner he, with them of man and beast +Select for life, shall in the ark be lodged, +And sheltered round; but all the cataracts +Of Heaven set open on the Earth shall pour +Rain, day and night; all fountains of the deep, +Broke up, shall heave the ocean to usurp +Beyond all bounds; till inundation rise +Above the highest hills: Then shall this mount +Of Paradise by might of waves be moved +Out of his place, pushed by the horned flood, +With all his verdure spoiled, and trees adrift, +Down the great river to the opening gulf, +And there take root an island salt and bare, +The haunt of seals, and orcs, and sea-mews' clang: +To teach thee that God attributes to place +No sanctity, if none be thither brought +By men who there frequent, or therein dwell. +And now, what further shall ensue, behold. +He looked, and saw the ark hull on the flood, +Which now abated; for the clouds were fled, +Driven by a keen north-wind, that, blowing dry, +Wrinkled the face of deluge, as decayed; +And the clear sun on his wide watery glass +Gazed hot, and of the fresh wave largely drew, +As after thirst; which made their flowing shrink +From standing lake to tripping ebb, that stole +With soft foot towards the deep; who now had stopt +His sluces, as the Heaven his windows shut. +The ark no more now floats, but seems on ground, +Fast on the top of some high mountain fixed. +And now the tops of hills, as rocks, appear; +With clamour thence the rapid currents drive, +Towards the retreating sea, their furious tide. +Forthwith from out the ark a raven flies, +And after him, the surer messenger, +A dove sent forth once and again to spy +Green tree or ground, whereon his foot may light: +The second time returning, in his bill +An olive-leaf he brings, pacifick sign: +Anon dry ground appears, and from his ark +The ancient sire descends, with all his train; +Then with uplifted hands, and eyes devout, +Grateful to Heaven, over his head beholds +A dewy cloud, and in the cloud a bow +Conspicuous with three lifted colours gay, +Betokening peace from God, and covenant new. +Whereat the heart of Adam, erst so sad, +Greatly rejoiced; and thus his joy broke forth. +O thou, who future things canst represent +As present, heavenly Instructer! I revive +At this last sight; assured that Man shall live, +With all the creatures, and their seed preserve. +Far less I now lament for one whole world +Of wicked sons destroyed, than I rejoice +For one man found so perfect, and so just, +That God vouchsafes to raise another world +From him, and all his anger to forget. +But say, what mean those coloured streaks in Heaven +Distended, as the brow of God appeased? +Or serve they, as a flowery verge, to bind +The fluid skirts of that same watery cloud, +Lest it again dissolve, and shower the earth? +To whom the Arch-Angel. Dextrously thou aimest; +So willingly doth God remit his ire, +Though late repenting him of Man depraved; +Grieved at his heart, when looking down he saw +The whole earth filled with violence, and all flesh +Corrupting each their way; yet, those removed, +Such grace shall one just man find in his sight, +That he relents, not to blot out mankind; +And makes a covenant never to destroy +The earth again by flood; nor let the sea +Surpass his bounds; nor rain to drown the world, +With man therein or beast; but, when he brings +Over the earth a cloud, will therein set +His triple-coloured bow, whereon to look, +And call to mind his covenant: Day and night, +Seed-time and harvest, heat and hoary frost, +Shall hold their course; till fire purge all things new, +Both Heaven and Earth, wherein the just shall dwell. + + + +Book XII + + +As one who in his journey bates at noon, +Though bent on speed; so here the Arch-Angel paused +Betwixt the world destroyed and world restored, +If Adam aught perhaps might interpose; +Then, with transition sweet, new speech resumes. +Thus thou hast seen one world begin, and end; +And Man, as from a second stock, proceed. +Much thou hast yet to see; but I perceive +Thy mortal sight to fail; objects divine +Must needs impair and weary human sense: +Henceforth what is to come I will relate; +Thou therefore give due audience, and attend. +This second source of Men, while yet but few, +And while the dread of judgement past remains +Fresh in their minds, fearing the Deity, +With some regard to what is just and right +Shall lead their lives, and multiply apace; +Labouring the soil, and reaping plenteous crop, +Corn, wine, and oil; and, from the herd or flock, +Oft sacrificing bullock, lamb, or kid, +With large wine-offerings poured, and sacred feast, +Shall spend their days in joy unblamed; and dwell +Long time in peace, by families and tribes, +Under paternal rule: till one shall rise +Of proud ambitious heart; who, not content +With fair equality, fraternal state, +Will arrogate dominion undeserved +Over his brethren, and quite dispossess +Concord and law of nature from the earth; +Hunting (and men not beasts shall be his game) +With war, and hostile snare, such as refuse +Subjection to his empire tyrannous: +A mighty hunter thence he shall be styled +Before the Lord; as in despite of Heaven, +Or from Heaven, claiming second sovranty; +And from rebellion shall derive his name, +Though of rebellion others he accuse. +He with a crew, whom like ambition joins +With him or under him to tyrannize, +Marching from Eden towards the west, shall find +The plain, wherein a black bituminous gurge +Boils out from under ground, the mouth of Hell: +Of brick, and of that stuff, they cast to build +A city and tower, whose top may reach to Heaven; +And get themselves a name; lest, far dispersed +In foreign lands, their memory be lost; +Regardless whether good or evil fame. +But God, who oft descends to visit men +Unseen, and through their habitations walks +To mark their doings, them beholding soon, +Comes down to see their city, ere the tower +Obstruct Heaven-towers, and in derision sets +Upon their tongues a various spirit, to rase +Quite out their native language; and, instead, +To sow a jangling noise of words unknown: +Forthwith a hideous gabble rises loud, +Among the builders; each to other calls +Not understood; till hoarse, and all in rage, +As mocked they storm: great laughter was in Heaven, +And looking down, to see the hubbub strange, +And hear the din: Thus was the building left +Ridiculous, and the work Confusion named. +Whereto thus Adam, fatherly displeased. +O execrable son! so to aspire +Above his brethren; to himself assuming +Authority usurped, from God not given: +He gave us only over beast, fish, fowl, +Dominion absolute; that right we hold +By his donation; but man over men +He made not lord; such title to himself +Reserving, human left from human free. +But this usurper his encroachment proud +Stays not on Man; to God his tower intends +Siege and defiance: Wretched man!what food +Will he convey up thither, to sustain +Himself and his rash army; where thin air +Above the clouds will pine his entrails gross, +And famish him of breath, if not of bread? +To whom thus Michael. Justly thou abhorrest +That son, who on the quiet state of men +Such trouble brought, affecting to subdue +Rational liberty; yet know withal, +Since thy original lapse, true liberty +Is lost, which always with right reason dwells +Twinned, and from her hath no dividual being: +Reason in man obscured, or not obeyed, +Immediately inordinate desires, +And upstart passions, catch the government +From reason; and to servitude reduce +Man, till then free. Therefore, since he permits +Within himself unworthy powers to reign +Over free reason, God, in judgement just, +Subjects him from without to violent lords; +Who oft as undeservedly enthrall +His outward freedom: Tyranny must be; +Though to the tyrant thereby no excuse. +Yet sometimes nations will decline so low +From virtue, which is reason, that no wrong, +But justice, and some fatal curse annexed, +Deprives them of their outward liberty; +Their inward lost: Witness the irreverent son +Of him who built the ark; who, for the shame +Done to his father, heard this heavy curse, +Servant of servants, on his vicious race. +Thus will this latter, as the former world, +Still tend from bad to worse; till God at last, +Wearied with their iniquities, withdraw +His presence from among them, and avert +His holy eyes; resolving from thenceforth +To leave them to their own polluted ways; +And one peculiar nation to select +From all the rest, of whom to be invoked, +A nation from one faithful man to spring: +Him on this side Euphrates yet residing, +Bred up in idol-worship: O, that men +(Canst thou believe?) should be so stupid grown, +While yet the patriarch lived, who 'scaped the flood, +As to forsake the living God, and fall +To worship their own work in wood and stone +For Gods! Yet him God the Most High vouchsafes +To call by vision, from his father's house, +His kindred, and false Gods, into a land +Which he will show him; and from him will raise +A mighty nation; and upon him shower +His benediction so, that in his seed +All nations shall be blest: he straight obeys; +Not knowing to what land, yet firm believes: +I see him, but thou canst not, with what faith +He leaves his Gods, his friends, and native soil, +Ur of Chaldaea, passing now the ford +To Haran; after him a cumbrous train +Of herds and flocks, and numerous servitude; +Not wandering poor, but trusting all his wealth +With God, who called him, in a land unknown. +Canaan he now attains; I see his tents +Pitched about Sechem, and the neighbouring plain +Of Moreh; there by promise he receives +Gift to his progeny of all that land, +From Hameth northward to the Desart south; +(Things by their names I call, though yet unnamed;) +From Hermon east to the great western Sea; +Mount Hermon, yonder sea; each place behold +In prospect, as I point them; on the shore +Mount Carmel; here, the double-founted stream, +Jordan, true limit eastward; but his sons +Shall dwell to Senir, that long ridge of hills. +This ponder, that all nations of the earth +Shall in his seed be blessed: By that seed +Is meant thy great Deliverer, who shall bruise +The Serpent's head; whereof to thee anon +Plainlier shall be revealed. This patriarch blest, +Whom faithful Abraham due time shall call, +A son, and of his son a grand-child, leaves; +Like him in faith, in wisdom, and renown: +The grandchild, with twelve sons increased, departs +From Canaan to a land hereafter called +Egypt, divided by the river Nile +See where it flows, disgorging at seven mouths +Into the sea. To sojourn in that land +He comes, invited by a younger son +In time of dearth, a son whose worthy deeds +Raise him to be the second in that realm +Of Pharaoh. There he dies, and leaves his race +Growing into a nation, and now grown +Suspected to a sequent king, who seeks +To stop their overgrowth, as inmate guests +Too numerous; whence of guests he makes them slaves +Inhospitably, and kills their infant males: +Till by two brethren (these two brethren call +Moses and Aaron) sent from God to claim +His people from enthralment, they return, +With glory and spoil, back to their promised land. +But first, the lawless tyrant, who denies +To know their God, or message to regard, +Must be compelled by signs and judgements dire; +To blood unshed the rivers must be turned; +Frogs, lice, and flies, must all his palace fill +With loathed intrusion, and fill all the land; +His cattle must of rot and murren die; +Botches and blains must all his flesh emboss, +And all his people; thunder mixed with hail, +Hail mixed with fire, must rend the Egyptians sky, +And wheel on the earth, devouring where it rolls; +What it devours not, herb, or fruit, or grain, +A darksome cloud of locusts swarming down +Must eat, and on the ground leave nothing green; +Darkness must overshadow all his bounds, +Palpable darkness, and blot out three days; +Last, with one midnight stroke, all the first-born +Of Egypt must lie dead. Thus with ten wounds +The river-dragon tamed at length submits +To let his sojourners depart, and oft +Humbles his stubborn heart; but still, as ice +More hardened after thaw; till, in his rage +Pursuing whom he late dismissed, the sea +Swallows him with his host; but them lets pass, +As on dry land, between two crystal walls; +Awed by the rod of Moses so to stand +Divided, till his rescued gain their shore: +Such wondrous power God to his saint will lend, +Though present in his Angel; who shall go +Before them in a cloud, and pillar of fire; +By day a cloud, by night a pillar of fire; +To guide them in their journey, and remove +Behind them, while the obdurate king pursues: +All night he will pursue; but his approach +Darkness defends between till morning watch; +Then through the fiery pillar, and the cloud, +God looking forth will trouble all his host, +And craze their chariot-wheels: when by command +Moses once more his potent rod extends +Over the sea; the sea his rod obeys; +On their embattled ranks the waves return, +And overwhelm their war: The race elect +Safe toward Canaan from the shore advance +Through the wild Desart, not the readiest way; +Lest, entering on the Canaanite alarmed, +War terrify them inexpert, and fear +Return them back to Egypt, choosing rather +Inglorious life with servitude; for life +To noble and ignoble is more sweet +Untrained in arms, where rashness leads not on. +This also shall they gain by their delay +In the wide wilderness; there they shall found +Their government, and their great senate choose +Through the twelve tribes, to rule by laws ordained: +God from the mount of Sinai, whose gray top +Shall tremble, he descending, will himself +In thunder, lightning, and loud trumpets' sound, +Ordain them laws; part, such as appertain +To civil justice; part, religious rites +Of sacrifice; informing them, by types +And shadows, of that destined Seed to bruise +The Serpent, by what means he shall achieve +Mankind's deliverance. But the voice of God +To mortal ear is dreadful: They beseech +That Moses might report to them his will, +And terrour cease; he grants what they besought, +Instructed that to God is no access +Without Mediator, whose high office now +Moses in figure bears; to introduce +One greater, of whose day he shall foretel, +And all the Prophets in their age the times +Of great Messiah shall sing. Thus, laws and rites +Established, such delight hath God in Men +Obedient to his will, that he vouchsafes +Among them to set up his tabernacle; +The Holy One with mortal Men to dwell: +By his prescript a sanctuary is framed +Of cedar, overlaid with gold; therein +An ark, and in the ark his testimony, +The records of his covenant; over these +A mercy-seat of gold, between the wings +Of two bright Cherubim; before him burn +Seven lamps as in a zodiack representing +The heavenly fires; over the tent a cloud +Shall rest by day, a fiery gleam by night; +Save when they journey, and at length they come, +Conducted by his Angel, to the land +Promised to Abraham and his seed:--The rest +Were long to tell; how many battles fought +How many kings destroyed; and kingdoms won; +Or how the sun shall in mid Heaven stand still +A day entire, and night's due course adjourn, +Man's voice commanding, 'Sun, in Gibeon stand, +'And thou moon in the vale of Aialon, +'Till Israel overcome! so call the third +From Abraham, son of Isaac; and from him +His whole descent, who thus shall Canaan win. +Here Adam interposed. O sent from Heaven, +Enlightener of my darkness, gracious things +Thou hast revealed; those chiefly, which concern +Just Abraham and his seed: now first I find +Mine eyes true-opening, and my heart much eased; +Erewhile perplexed with thoughts, what would become +Of me and all mankind: But now I see +His day, in whom all nations shall be blest; +Favour unmerited by me, who sought +Forbidden knowledge by forbidden means. +This yet I apprehend not, why to those +Among whom God will deign to dwell on earth +So many and so various laws are given; +So many laws argue so many sins +Among them; how can God with such reside? +To whom thus Michael. Doubt not but that sin +Will reign among them, as of thee begot; +And therefore was law given them, to evince +Their natural pravity, by stirring up +Sin against law to fight: that when they see +Law can discover sin, but not remove, +Save by those shadowy expiations weak, +The blood of bulls and goats, they may conclude +Some blood more precious must be paid for Man; +Just for unjust; that, in such righteousness +To them by faith imputed, they may find +Justification towards God, and peace +Of conscience; which the law by ceremonies +Cannot appease; nor Man the mortal part +Perform; and, not performing, cannot live. +So law appears imperfect; and but given +With purpose to resign them, in full time, +Up to a better covenant; disciplined +From shadowy types to truth; from flesh to spirit; +From imposition of strict laws to free +Acceptance of large grace; from servile fear +To filial; works of law to works of faith. +And therefore shall not Moses, though of God +Highly beloved, being but the minister +Of law, his people into Canaan lead; +But Joshua, whom the Gentiles Jesus call, +His name and office bearing, who shall quell +The adversary-Serpent, and bring back +Through the world's wilderness long-wandered Man +Safe to eternal Paradise of rest. +Mean while they, in their earthly Canaan placed, +Long time shall dwell and prosper, but when sins +National interrupt their publick peace, +Provoking God to raise them enemies; +From whom as oft he saves them penitent +By Judges first, then under Kings; of whom +The second, both for piety renowned +And puissant deeds, a promise shall receive +Irrevocable, that his regal throne +For ever shall endure; the like shall sing +All Prophecy, that of the royal stock +Of David (so I name this king) shall rise +A Son, the Woman's seed to thee foretold, +Foretold to Abraham, as in whom shall trust +All nations; and to kings foretold, of kings +The last; for of his reign shall be no end. +But first, a long succession must ensue; +And his next son, for wealth and wisdom famed, +The clouded ark of God, till then in tents +Wandering, shall in a glorious temple enshrine. +Such follow him, as shall be registered +Part good, part bad; of bad the longer scroll; +Whose foul idolatries, and other faults +Heaped to the popular sum, will so incense +God, as to leave them, and expose their land, +Their city, his temple, and his holy ark, +With all his sacred things, a scorn and prey +To that proud city, whose high walls thou sawest +Left in confusion; Babylon thence called. +There in captivity he lets them dwell +The space of seventy years; then brings them back, +Remembering mercy, and his covenant sworn +To David, stablished as the days of Heaven. +Returned from Babylon by leave of kings +Their lords, whom God disposed, the house of God +They first re-edify; and for a while +In mean estate live moderate; till, grown +In wealth and multitude, factious they grow; +But first among the priests dissention springs, +Men who attend the altar, and should most +Endeavour peace: their strife pollution brings +Upon the temple itself: at last they seise +The scepter, and regard not David's sons; +Then lose it to a stranger, that the true +Anointed King Messiah might be born +Barred of his right; yet at his birth a star, +Unseen before in Heaven, proclaims him come; +And guides the eastern sages, who inquire +His place, to offer incense, myrrh, and gold: +His place of birth a solemn Angel tells +To simple shepherds, keeping watch by night; +They gladly thither haste, and by a quire +Of squadroned Angels hear his carol sung. +A virgin is his mother, but his sire +The power of the Most High: He shall ascend +The throne hereditary, and bound his reign +With Earth's wide bounds, his glory with the Heavens. +He ceased, discerning Adam with such joy +Surcharged, as had like grief been dewed in tears, +Without the vent of words; which these he breathed. +O prophet of glad tidings, finisher +Of utmost hope! now clear I understand +What oft my steadiest thoughts have searched in vain; +Why our great Expectation should be called +The seed of Woman: Virgin Mother, hail, +High in the love of Heaven; yet from my loins +Thou shalt proceed, and from thy womb the Son +Of God Most High: so God with Man unites! +Needs must the Serpent now his capital bruise +Expect with mortal pain: Say where and when +Their fight, what stroke shall bruise the victor's heel. +To whom thus Michael. Dream not of their fight, +As of a duel, or the local wounds +Of head or heel: Not therefore joins the Son +Manhood to Godhead, with more strength to foil +Thy enemy; nor so is overcome +Satan, whose fall from Heaven, a deadlier bruise, +Disabled, not to give thee thy death's wound: +Which he, who comes thy Saviour, shall recure, +Not by destroying Satan, but his works +In thee, and in thy seed: Nor can this be, +But by fulfilling that which thou didst want, +Obedience to the law of God, imposed +On penalty of death, and suffering death; +The penalty to thy transgression due, +And due to theirs which out of thine will grow: +So only can high Justice rest appaid. +The law of God exact he shall fulfil +Both by obedience and by love, though love +Alone fulfil the law; thy punishment +He shall endure, by coming in the flesh +To a reproachful life, and cursed death; +Proclaiming life to all who shall believe +In his redemption; and that his obedience, +Imputed, becomes theirs by faith; his merits +To save them, not their own, though legal, works. +For this he shall live hated, be blasphemed, +Seised on by force, judged, and to death condemned +A shameful and accursed, nailed to the cross +By his own nation; slain for bringing life: +But to the cross he nails thy enemies, +The law that is against thee, and the sins +Of all mankind, with him there crucified, +Never to hurt them more who rightly trust +In this his satisfaction; so he dies, +But soon revives; Death over him no power +Shall long usurp; ere the third dawning light +Return, the stars of morn shall see him rise +Out of his grave, fresh as the dawning light, +Thy ransom paid, which Man from death redeems, +His death for Man, as many as offered life +Neglect not, and the benefit embrace +By faith not void of works: This God-like act +Annuls thy doom, the death thou shouldest have died, +In sin for ever lost from life; this act +Shall bruise the head of Satan, crush his strength, +Defeating Sin and Death, his two main arms; +And fix far deeper in his head their stings +Than temporal death shall bruise the victor's heel, +Or theirs whom he redeems; a death, like sleep, +A gentle wafting to immortal life. +Nor after resurrection shall he stay +Longer on earth, than certain times to appear +To his disciples, men who in his life +Still followed him; to them shall leave in charge +To teach all nations what of him they learned +And his salvation; them who shall believe +Baptizing in the profluent stream, the sign +Of washing them from guilt of sin to life +Pure, and in mind prepared, if so befall, +For death, like that which the Redeemer died. +All nations they shall teach; for, from that day, +Not only to the sons of Abraham's loins +Salvation shall be preached, but to the sons +Of Abraham's faith wherever through the world; +So in his seed all nations shall be blest. +Then to the Heaven of Heavens he shall ascend +With victory, triumphing through the air +Over his foes and thine; there shall surprise +The Serpent, prince of air, and drag in chains +Through all his realm, and there confounded leave; +Then enter into glory, and resume +His seat at God's right hand, exalted high +Above all names in Heaven; and thence shall come, +When this world's dissolution shall be ripe, +With glory and power to judge both quick and dead; +To judge the unfaithful dead, but to reward +His faithful, and receive them into bliss, +Whether in Heaven or Earth; for then the Earth +Shall all be Paradise, far happier place +Than this of Eden, and far happier days. +So spake the Arch-Angel Michael; then paused, +As at the world's great period; and our sire, +Replete with joy and wonder, thus replied. +O Goodness infinite, Goodness immense! +That all this good of evil shall produce, +And evil turn to good; more wonderful +Than that which by creation first brought forth +Light out of darkness! Full of doubt I stand, +Whether I should repent me now of sin +By me done, and occasioned; or rejoice +Much more, that much more good thereof shall spring; +To God more glory, more good-will to Men +From God, and over wrath grace shall abound. +But say, if our Deliverer up to Heaven +Must re-ascend, what will betide the few +His faithful, left among the unfaithful herd, +The enemies of truth? Who then shall guide +His people, who defend? Will they not deal +Worse with his followers than with him they dealt? +Be sure they will, said the Angel; but from Heaven +He to his own a Comforter will send, +The promise of the Father, who shall dwell +His Spirit within them; and the law of faith, +Working through love, upon their hearts shall write, +To guide them in all truth; and also arm +With spiritual armour, able to resist +Satan's assaults, and quench his fiery darts; +What man can do against them, not afraid, +Though to the death; against such cruelties +With inward consolations recompensed, +And oft supported so as shall amaze +Their proudest persecutors: For the Spirit, +Poured first on his Apostles, whom he sends +To evangelize the nations, then on all +Baptized, shall them with wonderous gifts endue +To speak all tongues, and do all miracles, +As did their Lord before them. Thus they win +Great numbers of each nation to receive +With joy the tidings brought from Heaven: At length +Their ministry performed, and race well run, +Their doctrine and their story written left, +They die; but in their room, as they forewarn, +Wolves shall succeed for teachers, grievous wolves, +Who all the sacred mysteries of Heaven +To their own vile advantages shall turn +Of lucre and ambition; and the truth +With superstitions and traditions taint, +Left only in those written records pure, +Though not but by the Spirit understood. +Then shall they seek to avail themselves of names, +Places, and titles, and with these to join +Secular power; though feigning still to act +By spiritual, to themselves appropriating +The Spirit of God, promised alike and given +To all believers; and, from that pretence, +Spiritual laws by carnal power shall force +On every conscience; laws which none shall find +Left them inrolled, or what the Spirit within +Shall on the heart engrave. What will they then +But force the Spirit of Grace itself, and bind +His consort Liberty? what, but unbuild +His living temples, built by faith to stand, +Their own faith, not another's? for, on earth, +Who against faith and conscience can be heard +Infallible? yet many will presume: +Whence heavy persecution shall arise +On all, who in the worship persevere +Of spirit and truth; the rest, far greater part, +Will deem in outward rites and specious forms +Religion satisfied; Truth shall retire +Bestuck with slanderous darts, and works of faith +Rarely be found: So shall the world go on, +To good malignant, to bad men benign; +Under her own weight groaning; till the day +Appear of respiration to the just, +And vengeance to the wicked, at return +Of him so lately promised to thy aid, +The Woman's Seed; obscurely then foretold, +Now ampler known thy Saviour and thy Lord; +Last, in the clouds, from Heaven to be revealed +In glory of the Father, to dissolve +Satan with his perverted world; then raise +From the conflagrant mass, purged and refined, +New Heavens, new Earth, ages of endless date, +Founded in righteousness, and peace, and love; +To bring forth fruits, joy and eternal bliss. +He ended; and thus Adam last replied. +How soon hath thy prediction, Seer blest, +Measured this transient world, the race of time, +Till time stand fixed! Beyond is all abyss, +Eternity, whose end no eye can reach. +Greatly-instructed I shall hence depart; +Greatly in peace of thought; and have my fill +Of knowledge, what this vessel can contain; +Beyond which was my folly to aspire. +Henceforth I learn, that to obey is best, +And love with fear the only God; to walk +As in his presence; ever to observe +His providence; and on him sole depend, +Merciful over all his works, with good +Still overcoming evil, and by small +Accomplishing great things, by things deemed weak +Subverting worldly strong, and worldly wise +By simply meek: that suffering for truth's sake +Is fortitude to highest victory, +And, to the faithful, death the gate of life; +Taught this by his example, whom I now +Acknowledge my Redeemer ever blest. +To whom thus also the Angel last replied. +This having learned, thou hast attained the sum +Of wisdom; hope no higher, though all the stars +Thou knewest by name, and all the ethereal powers, +All secrets of the deep, all Nature's works, +Or works of God in Heaven, air, earth, or sea, +And all the riches of this world enjoyedst, +And all the rule, one empire; only add +Deeds to thy knowledge answerable; add faith, +Add virtue, patience, temperance; add love, +By name to come called charity, the soul +Of all the rest: then wilt thou not be loth +To leave this Paradise, but shalt possess +A Paradise within thee, happier far.-- +Let us descend now therefore from this top +Of speculation; for the hour precise +Exacts our parting hence; and see!the guards, +By me encamped on yonder hill, expect +Their motion; at whose front a flaming sword, +In signal of remove, waves fiercely round: +We may no longer stay: go, waken Eve; +Her also I with gentle dreams have calmed +Portending good, and all her spirits composed +To meek submission: thou, at season fit, +Let her with thee partake what thou hast heard; +Chiefly what may concern her faith to know, +The great deliverance by her seed to come +(For by the Woman's seed) on all mankind: +That ye may live, which will be many days, +Both in one faith unanimous, though sad, +With cause, for evils past; yet much more cheered +With meditation on the happy end. +He ended, and they both descend the hill; +Descended, Adam to the bower, where Eve +Lay sleeping, ran before; but found her waked; +And thus with words not sad she him received. +Whence thou returnest, and whither wentest, I know; +For God is also in sleep; and dreams advise, +Which he hath sent propitious, some great good +Presaging, since with sorrow and heart's distress +Wearied I fell asleep: But now lead on; +In me is no delay; with thee to go, +Is to stay here; without thee here to stay, +Is to go hence unwilling; thou to me +Art all things under $Heaven, all places thou, +Who for my wilful crime art banished hence. +This further consolation yet secure +I carry hence; though all by me is lost, +Such favour I unworthy am vouchsafed, +By me the Promised Seed shall all restore. +So spake our mother Eve; and Adam heard +Well pleased, but answered not: For now, too nigh +The Arch-Angel stood; and, from the other hill +To their fixed station, all in bright array +The Cherubim descended; on the ground +Gliding meteorous, as evening-mist +Risen from a river o'er the marish glides, +And gathers ground fast at the labourer's heel +Homeward returning. High in front advanced, +The brandished sword of God before them blazed, +Fierce as a comet; which with torrid heat, +And vapour as the Libyan air adust, +Began to parch that temperate clime; whereat +In either hand the hastening Angel caught +Our lingering parents, and to the eastern gate +Led them direct, and down the cliff as fast +To the subjected plain; then disappeared. +They, looking back, all the eastern side beheld +Of Paradise, so late their happy seat, +Waved over by that flaming brand; the gate +With dreadful faces thronged, and fiery arms: +Some natural tears they dropt, but wiped them soon; +The world was all before them, where to choose +Their place of rest, and Providence their guide: +They, hand in hand, with wandering steps and slow, +Through Eden took their solitary way.
