Когда я как-то упрекнул его за бесполезные бессонные ночи, после которых он впадал в болезненное уныние, он взглянул на меня с горькой улыбкой и раскрыл передо мною историю города Рима. В этой книге, в двадцатой главе жизнеописания папы Александра Шестого, я прочел следующие строки, навсегда оставшиеся в моей памяти",

Цезарь считал, что достаточно применить одно из тех средств, которые он всегда держал наготове для своих ближайших друзей, а именно: пресловутый ключ, которым то одного, то другого просили отпереть некий шкаф. На ключе был крохотный железный шип – недосмотр слесаря. Каждый, кто трудился над тугим замком, накалывал себе палец и на другой день умирал. Был еще перстень с львиной головой, который Цезарь надевал, когда хотел пожать руку той или иной особе. Лев впивался в кожу этих избранных рук, и через сутки наступала смерть.",

Роспильози, в восторге от своего нового звания и предвкушая пир, явился с самым веселым лицом. Спада, человек осторожный и очень любивший своего племянника, молодого офицера, подававшего блистательные надежды, взял лист бумаги, перо и написал свое завещание. Потом он послал сказать племяннику, чтобы тот ждал его у виноградников; но посланный, по-видимому, не застал того дома.",

С тех пор как христианство – глубоко цивилизующая сила – восторжествовало в Риме, уже не центурион являлся объявить от имени тирана: «Цезарь желает, чтобы ты умер», а любезный легат с улыбкой говорил от имени папы: «Его святейшество желает, чтобы вы с ним отобедали»"
