Amphion and Zethus. These founded Thebes with its seven gates, and built a wall all round it; for strong though they were they could not hold Thebes till they had walled it.
Notable among these children were Dionysus, son of Cadmus ' daughter Semele; Heracles, son of Alcmena; Perseus, son of Danae ;
Amphion and Zethus, sons of Antiope; Helen, Clytemnestra, and the Dioscuri (or some combination of them), children of Leda.
