Deianira
Deianira In Greek mythology, second wife of Heracles; daughter of Dionysus (or Oeneus) and Althaea; half sister of Gorge, Meleager, and Toxeus; mother of Ctesippus, Hyllus, and Macaria. She accidentally killed Heracles when she sent him, by the centaur Nessus, a garment soaked in poisoned blood, which she believed would renew Heracles’ love for her. Ovid’s Metamorphoses (book 9) and Chaucer’s “The Monk’s Tale,” part of The Canterbury Tales, all refer to the myth.
