Classical Athens
In Classical Athens, there was no exact equivalent of the English term "adultery", but the similar "moicheia" () was a criminal offence often translated as adultery by scholars. Athenian "moicheia" was restricted to illicit sex with free women, and so men could legally have extra-marital sex with slaves and prostitutes. Famously, Athenian culture and adultery laws considered seduction of a citizen woman a worse crime than rape.
