A son of Icarius and Periboea, and a brother of Penelope. Historians of Peloponnesian antiquities said that what Clytemnestra's Erinyes did to Orestes in Arcadia took place before the trial at the Areopagus; that his accuser was not Tyndareus, who no longer lived, but Perilaus, who asked for vengeance for the mother's murder in that he was a cousin of Clytemnestra.
