The god Hermes taught Amphion music and gave him a beautiful golden lyre. Both brothers were supposed to have build the walls of Thebes, while Amphion played his lyre. The magic of his music caused the stones to move into place on their own accord.
Amphion is the son of Zeus and the nymph Antiope, the queen of Thebes. His twin brother is Zethus. When they reached maturity, the two brothers exacted a terrible revenge upon king Lycus of Thebes and his wife Dirce, for she had been treating their mother Antiope as a slave. They punished Dirce by tying her to the horns of a wild bull. He later married Niobe, and they had six sons and six daughters, called the Niobids.
