Alcmaeon

Alcmaeon, the legendary son of Amphiaraus and Eriphyle, who killed his mother because she betrayed her husband into the fatal expedition against Thebes. Pursued by the Furies, he obtained purification at the hands of Phegeus of Arcadia, and married Alphesiboea, his preserver's daughter. He abandoned her for Callirrhoe, daughter of Achelous; but his first wife's brethren punished his fickleness with death, being themselves killed subsequently by Callirrhoe's sons. - This personage must not be confounded with Alcmaeon, the descendant of Nestor, and founder of the family of the Alcmaeonidae - at Athens; nor with Alcmaeon, the Pythagorean philosopher of Crotona (500 B.C.), who was the first dissector of animals for scientific purposes.
