Chiron
Appearance
In Greek mythology, Chiron ("hand") was a centaur who was unlike most centaurs in that he was kind, intelligent and civilized. He was a son of Cronus and Philyra.
He was probably a Thessalonian god, later subsumed into the Greek pantheon as a centaur.
He tutored Asclepius, Theseus, Achilles and Jason.
Heracles accidentally shot him with a poisonous arrow and Chiron willingly gave up his immortality to escape the pain. He was placed in the sky as the constellation Sagittarius.
