The Golden Fleece

He had for a friend one who was the wisest of all creatures Chiron the centaur; Chiron who was half man and half horse; Chiron who had lived and was yet to live measureless years. Chiron had fostered Heracles, and it might be that he would not refuse to foster Jason, Aeson's child.

Away in the fastnesses of Mount Pelion Chiron dwelt; once Aeson had been with him and had seen the centaur hunt with his great bow and his great spears. And Aeson knew a way that one might come to him; Chiron himself had told him of the way.
