Chiron was a centaur-that is to say, half man and half horse-and he had his being in the legends of Old Greece. For all the brutish part of him, Chiron was a truly noble creature, for it was he who trained and fostered the prowess of nearly all the old Greek heroes. He was skilled alike in the arts of war and peace, being the instructor of mighty youths like Jason and Hercules, and the other valiant fellows who sailed in quest of the Golden Fleece, besides teaching medicine to Aesculapius and the enchanting art of the lyre to Orpheus. Never before or since has there been a professor so widely versed in all the arts and sciences as Chiron, whose name to-day is often used to denote universal knowledge and instruction. Chiron was wounded by Hercules in the Battle of the Centaurs, and praying Jupiter to be deprived of his immortality, his plea was granted, and he was placed among the constellations under the name of Sagittarius.
