Amphion became a great singer and musician after Hermes taught him to play and gave him a golden lyre, Zethus a hunter and herdsman. They punished King Lycus and Queen Dirce for cruel treatment of Antiope, their mother, who was treated as a slave. Dirce was tied to the horns of a bull as revenge. They built and fortified Thebes, huge blocks of stone forming themselves into walls at the sound of Amphion's lyre. Amphion married Niobe, and killed himself after the loss of his wife and children. Zethus married Aedon, or sometimes Thebe. The brothers were buried in one grave.
