Roman Vice
On the theme of prostitution, there is no single detailed description by a classic Roman author. The numerous sources of Roman antiquity about prostitution vary widely in character. Mostly they are in parenthetical remarks in texts about other themes, both historical and literary. The value of many of the comments are difficult to interpret today. In particular, the literary sources are mainly related to ancient Rome, and not to later periods of the Roman Empire. The main authors relied upon are Catullus, Ovid, Martial and Petronius.
Another source comes from parts of Roman law that regulate prostitution, and describe their provisions in some detail. Epigraphic texts are also available, especially the graffiti and murals from Pompeii. Finally, there are, especially from Egypt, texts on papyri that refer to the economic dimensions of prostitution.
