It is perhaps difficult to conceive how it could have been otherwise, considering the examples set by the emperors. It requires no small research to discover a single character in the long list that was not stained by the grossest habits. Julius Cæsar, "the bald adulterer," was commonly said to be "husband of all men's wives."[135] Augustus, whose youth had been so dissolute as to suggest a most contemptuous epigram, employed men in his old age to procure matrons and maidens, whom these purveyors of imperial lust examined as though they had been horses at a public sale.[136] The amours of Tiberius in his retreat at Capreæ can not be described. It will suffice to say there was no invention of infamy which he did not patronise; that no young person of any charms was safe from his lust. More than one senator felt that safety required he should remove his handsome wife or pretty daughter from Rome, for Tiberius was ever ready to avenge obstacles with death. The sad fate of the beautiful Mallonia, who stabbed herself during a lawsuit which the emperor had instituted against her because she refused to comply with his beastly demands, gives a picture of the age.[137] Caligula, who made some changes in the tax levied on prostitutes, and established a brothel in the palace, commenced life by debauching his sisters, and ended it by giving grand dinners, during which he would remove from the room any lady he pleased, and, after spending a few minutes with her in private, return and give an account of the interview for the amusement of the company.[138] Messalina so far eclipsed Claudius in depravity that the "profuse debauches" of the former appear, by contrast, almost moderate and virtuous.[139] Nero surpassed his predecessors in cynic recklessness. He was an habitual frequenter of houses of prostitution. He dined in public at the great circus among a crowd of prostitutes. He founded, on the shore of the Gulf of Naples, houses of prostitution, and filled them with females, whose dissolute habits were their recommendation to his notice. The brief sketch of his journeys given by Tacitus, and the allusions to his minister of pleasures, Tigellinus, leave no room for doubting that he was a monster of depravity.[140]
