Eriphyle

In Greek mythology, Eriphyle (Ancient Greek: Ἐριφύλη), daughter of Talaus, was the mother of Alcmaeon and the wife of Amphiaraus. Eriphyle persuaded Amphiaraus to take part in the raid that initiated the mythic tale of the Seven Against Thebes, though she knew he would die. She had been persuaded by Polynices, who offered her the necklace of Harmonia for her assistance.
