When Jason, the son of the dethroned King of Iolchos, was a little boy, he was sent away from his parents, and placed under the queerest schoolmaster that ever you heard of. This learned person was one of the people, or quadrupeds, called Centaurs. He lived in a cavern, and had the body and legs of a white horse, with the head and shoulders of a man. His name was Chiron; and, in spite of his odd appearance, he was a very excellent teacher, and had several scholars, who afterwards did him credit by making a great figure in the world. The famous Hercules was one, and so was Achilles, and Philoctetes likewise, and Aesculapius, who acquired immense repute as a doctor.
