Chiron, in Greek mythology, the wisest of all the centaurs, reputed to be the son of Cronus (Saturn) and Philyra, born before the Ar-gonautic expedition. He was taught by Apollo and Diana, and was skilled in hunting, gymnastics, botany, medicine, music, and the art of divining future events. He lived at the foot of Mt. Pelion, in Thessaly, and such was his fame for wisdom that almost all the noble youths of Greece resorted to his cave for instruction. Among his pupils were Hercules, Peleus, who was also his grandson, Nestor, Castor and Pollux, Ajax, Achilles, Ulysses, and Diomedes. When the other centaurs were about to kill his grandson Peleus, Chiron saved his life, and it was only by means of Chiron that Peleus was enabled to obtain his beloved Thetis for his wife. The Argonauts, on their expedition in quest of the golden fleece, stopped at the abode of Chiron, were kindly entertained by him, and received from him a chart of the constellations, which he made to assist them in their navigation. Hercules was one of his favorite pupils, but an arrow from his bow shot at another centaur unfortunately killed his beloved preceptor.

Chiron was immortal; but when pierced by the arrow of Hercules, he gave up his immortality to Prometheus, and died.
