The Satyricon (1st c. AD) by Petronius
"The Satyricon is a classic of comedy, a superbly funny picture of Nero's Rome as seen through the eyes of Petronius, its most amorous and elegant courtier. William Arrowsmith's translation—a lively, modern, unexpurgated text—recaptures all the ribald humor of Petronius's picaresque satire. It tells the hilarious story of the pleasure-seeking adventures of an educated rogue, Encolpius, his handsome serving boy, Giton, and Ascyltus, who lusts after Giton—three impure pilgrims who live by their wits and other men's purses. The Satyricon unfailingly turns every weakness of the flesh, every foible of the mind, to laughter."
