The son of Zeus and Antiope, brought up with his twin-brother Zethus on Mount Cithaeron, where he practiced singing to the lyre. When the brothers grew up and discovered their descent, they marched against Thebes, and put to death its king Lycus and his wife Dirce for having treated their mother with cruelty. They then fortified Thebes by a wall, to make which the stones moved of their own accord to the music of Amphion's lyre. He married Niobe, and killed himself from grief when all his children were destroyed by Apollo.
