Death of Heracles.
    When [late in his career] Heracles (Hercules) had routed Oechalia and gained the princess Iole, he sent his companion Lichas to bring back from his wife Deianeira a white garment to wear for a thanksgiving sacrifice. Deianeira, fearful that Heracles would put her aside in favor of the much younger Iole, remembered the dying words of the centaur Nessus: a garment dipped in his blood would win back her husband's love. Deianeira sent the blood-soaked shirt to Heracles, not realizing that Nessus had played a fatal trick on her.
    As the hero approached the sacrificial flame, the poisoned shirt caught fire and clung to his flesh. Ravaged by pain, he threw Lichas into the sea and had himself brought back to Mount Oeta in Trachis, where he was placed on a huge funeral pyre. He then instructed his son, Hyllus, to marry Iole when he came of age and gave his bow to the shepherd Peoas (or to Peoas's son, Philoctetes) in exchange for lighting the pyre. Meanwhile, Deianeira, devasted at what she had done, committed suicide.
