The daughter of king Nycteus of Thebes, or, according to others, of the river-god Asopus. She was seduced by Zeus and fled of shame to Epopeus, king of Sicyon, who married her. Nycteus' attempts to get her back were unsuccessful, and upon his deathbed he charged his brother Lycus to fulfil that task. Lycus and his army marched towards Sicyon, destroyed the city and killed Epopeus. He took Antiope with him to Thebes and gave her as a slave to his own wife Dirce. Dirce mistreated Antiope severely, but she managed to escape and was finally reunited with her sons Amphion and Zethus, her children with Zeus. Her twins exacted a terrible vengeance upon Dirce. Later Antiope married Phocus.
