affection". Plato's Symposium also includes a creation myth that explains homo- and heterosexuality (Aristophanes speech) and celebrates the pederastic tradition and erotic love between men (Pausanias speech), as does another of his dialogues, Phaedrus. The tradition of pederasty in ancient Greece (as early as 650 BC) and later the acceptance of limited homosexuality in ancient Rome infused an awareness of male-male attraction and sex into ancient poetry. In the second of Virgil's Eclogues (1st century BC), the shepherd Corydon proclaims his love for the boy Alexis. Some of the erotic poetry of Catullus in the same century is directed at other men (Carmen 48, 50, and 99), and in a wedding hymn (Carmen 61) he portrays a male concubine about to be supplanted by his master's future wife. The first line of his infamous invective Carmen 16 — which has been called "one of the filthiest expressions ever written in Latin—or in any other language, for that matter" — contains explicit homosexual sex acts. The Satyricon by Petronius is a Latin work of fiction detailing the misadventures of Encolpius and his lover, a handsome and promiscuous sixteen-year-old servant boy named Giton. Written in the 1st century AD during the reign of Nero, it is the earliest known text of its kind depicting homosexuality. In the celebrated Japanese work The Tale of Genji, written by Murasaki Shikibu in the early 11th century, the title character Hikaru Genji is rejected by the lady Utsusemi in chapter 3 and instead sleeps with her young brother: "Genji pulled the boy down beside him ... Genji, for his part, or so one is informed, found the boy more attractive than his chilly sister." Antonio Rocco's Alcibiades the Schoolboy, published anonymously in 1652, is an Italian dialogue written as a defense of homosexual sodomy. The first such explicit work known to be written since ancient times, its intended purpose as a "Carnivalesque satire", a defense of pederasty, or a work of pornography is unknown, and debated. Several medieval European works contain references to homosexuality, such as in Giovanni Boccaccios Decameron or Lanval, a French lai, in which the knight Lanval is accused by Guinevere of having "no desire for women". Others include homosexual themes, like Yde et Olive. 18th and 19th centuries The era known as the Age of Enlightenment (the 1650s to the 1780s) gave rise to, in part, a general challenge to the traditional
