(fab. hist.), a sister of Adrastus king of Argos, who married Amphiarau. She was daughter of Talaus and Lisimache. When her husband concealed himself that he might not accompany the Argives in their expedition against Thebes, where he knew he was to perish, Eriphyle suffered herself to be bribed by Polynices with a golden necklace which had been formerly given to Hermione by the goddes Venus, and she discovered where Amphiarau was. This treachery of Eriphyle compelled him to go to the war; but before he departed, he charged his son Alcmeon to murder his mother as soon as he was informed of his death. Amphiarau perished in the expedition; and his death was no sooner known than his last injunctions were obeyed, and Eriphyle was murdered by the hands of her son.
