Vistilia is a conundrum. Daughter of a noble family, her brother is generally thought to be the Praetor Sextus Vistilius, who was a close friend of Drusus, the younger brother of the Emperor Tiberius. Tacitus reports that, high-born and socially prominent matrona though she was, she entered her name on the public list of prostitutes, blatantly flaunting the strict matronal code advocated by Augustus for the upper classes (see Social Class). While prostitution as a means of survival for a lower-class Roman woman, single or with family, was understandable, it is hard to explain why an aristocratic woman would resort to advertising her countercultural sexual behavior in that climate, especially in the knowledge that the two Julias, daughter and granddaughter of Augustus, had earlier been exiled for much less visible public immorality under the Lex Iulia de Maritandis. Perhaps Vistilia was testing the temper of the times under Tiberius, or was emulating the freedoms claimed by the "new women" of love elegy. Married six times, she had at least two children by the time of her conviction and exile in 19 CE. Her daughter, Milonia Caesonia, later also identified as a public prostitute, became the fourth wife of the Emperor Caligula. Vistilia's son, Gnaeus Domitius Corbulo, became a successful general and father to Domitia Longina, who married the Emperor Domitian.
