or Alcmeon
In Greek mythology , the son of the seer Amphiaraus.
The seer had been persuaded by his wife to join the expedition of the Seven Against Thebes . On realizing that he would die, he charged Alcmaeon and his other sons with avenging his death. Alcmaeon led the sons of the seven in the destruction of Thebes and then obeyed his father's injunction to kill his mother, a crime for which the Furies drove him mad. He was purified by King Phegeus of Psophis, whose daughter he married but subsequently killed. Following the advice of an oracle, he settled on an island at the mouth of the Achelous River, where he married again, but was killed by Phegeus and his sons.
