Vistilia was an ancient Roman woman who registered herself as a prostitute, possibly to avoid charges of adultery.
[1][9][10] Instead, many scholars suggest that she registered herself as a prostitute in order to take advantage of a legal loophole in Roman law, to avoid prosecution for adultery.
[11][1] Suetonius described this practice of registering as a prostitute despite not being one, in order to avoid prosecution, though he did not mention Vistilia specifically.
[13] Her husband, Titidius Labeo, when asked why he had not tried to enforce the statutory penalty, stated the consultation period (which was sixty days) had not yet expired.
[14] The senate decided to prosecute only Vistilia (under Roman law, husbands who did not immediately punish adulterous wives could be tried as pimps).
