Amphion and Zethus
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. At Thebes Antiope now suffered from the persecution of Dirce, the wife of Lycus, but at last escaped towards Eleutherae, and there found shelter, unknowingly, in the house where her two sons were living as herdsmen. This is the situation in Euripides' "Antiope", which turns upon the recognition of mother and sons and their rescue of her.
