Deianira (Δηϊάνειρα) combines the Greek dēïos (slaying) and anēr (man) — "man-destroyer." Heracles's last wife, who unwittingly poisoned him with a tunic dipped in the centaur Nessus's blood, then took her own life in grief.
Featured in Sophocles' Trachiniae and Handel's opera Hercules (1745).
Deianira reduces to five — the number of Greek tragedy.
