In fact, #Asklepios learned the art of medicine from #Chiron, a centaur raised and educated by #Apollon. Chiron in turn raised and educated many famous heroes in their youth, among them #Achilles, Apollon's son Aristaios, and Kokytos, whom Chiron had taught medicine and who cared for #Adonis when he was wounded by the wild boar.
Chiron was wounded by an arrow dipped in the blood of the hydra, giving up is immortality to end his agony. The healer could not heal himself. 😔
