Mnemosyne — Classical Greek Myth Library

Chiron (Cheiron), son of Cronus and the nymph Philyra, was the wise centaur of Mount Pelion—unlike the violent breed born of Ixion’s cloud. Immortal and just, he taught hunting, medicine, music, and righteousness to a roll of heroes: Asclepius, Jason, Achilles, Actaeon, and others named in Pindar and the handbooks. His cave was the school of the heroic age. During Heracles’ fourth labor the centaurs of Pholoë, maddened by the scent of open wine, fled to Malea where Chiron then dwelt. An arrow of Heracles, tipped with the Lernaean Hydra’s poison, passed through another centaur and lodged in Chiron’s knee. The wound would not heal. Immortal yet in endless agony, Chiron withdrew into his cave. Later, when Heracles needed to free Prometheus—bound for the theft of fire—Zeus permitted a bargain: Chiron could surrender his immortality to the Titan (or die in his stead, in the Apollodorean phrasing) and so escape the pain. Thus the teacher of heroes ends not in battle glory but in a gift of death: immortality traded so that Prometheus might live unbound and Chiron’s torment cease. The myth fixes Chiron as both the civilizing tutor of the next generation and the unintended victim of Heracles’ poisoned shafts—the same Hydra venom that will later kill the hero himself through Nessus’s blood.
