The Satyricon
Satyricon (or Satyrica) is a Latin work of fiction in a mixture of prose & poetry (prosimetrum). It's thought to have been written by Gaius Petronius Arbiter, tho the manuscript tradition identifies the author as a certain Titus Petronius. As with the Metamorphoses of Apuleius, classicists often describe it as a Roman novel, without necessarily implying continuity with the modern literary form. Surviving portions of the text detail the misadventures of the narrator, Encolpius, & his lover, a handsome 16-year-old boy, Giton. Throughout the novel, Encolpius has a hard time keeping his lover faithful to him as he's constantly being enticed away by others. Encolpius's friend Ascyltus (who seems to have previously been in a relationship with Encolpius) is another major character.
