Ovid lists a number of writers known for salacious material whose works are now lost. Greek sex manuals and "straightforward pornography" were published under the name of famous "heterai" (courtesans), and circulated in Rome. The robustly sexual "Milesiaca" of Aristides was translated by Sisenna, one of the praetors of 78 BC. Ovid calls the book a collection of misdeeds "(crimina)", and says the narrative was laced with dirty jokes. After the Battle of Carrhae, the Parthians were reportedly shocked to find the "Milesiaca" in the baggage of Marcus Crassus's officers.
