In Greek mythology, Antiope (/ænˈtaɪ.əpiː/; Greek: Ἀντιόπη) was the daughter of the Boeotian river god Asopus, according to Homer; in later sources she is called the daughter of the “nocturnal” king Nycteus of Thebes or, in the Cypria, of Lycurgus, but for Homer her site is purely Boeotian. Her beauty attracted Zeus, who, assuming the form of a satyr, took her by force. This is the sole mythic episode in which Zeus is transformed into a satyr. After this she was carried off by Epopeus, who was venerated as a hero in Sicyon; he would not give her up till compelled by her uncle Lycus (brother of Nycteus). On the way home she gave birth, in the neighbourhood of Eleutherae on Mount Cithaeron, to the twins Amphion and Zethus, of whom Amphion was the son of the god, and Zethus the son of Epopeus. Both were left to be brought up by herdsmen.
