Deianeira

Deianeira, daughter of Ænens and Æthea, and sister of Meleager. She became the wife of Hercules, but unwittingly caused his death by sending him the mantle of the centaur Nessus, which was said to have the property of preserving love, but was really steeped in fatal poison. The poison entering his frame, the hero suffered such agony that he ordered a funeral pyre to be erected in Mount Æta, and cast himself into the flames, whereupon Deianeira hanged herself from grief.
