Aeson, king of Iolcus, was forced to fly from his dominions, which had been usurped by his younger brother, Pelias, and with difficulty succeeded in saving the life of his young son, Jason, who was at that time only ten years of age. He intrusted him to the care of the Centaur Chiron, by whom he was carefully trained in company with other noble youths, who, like himself, afterwards signalized themselves by their bravery and heroic exploits. For ten years Jason remained in the cave of the Centaur, by whom he was instructed in all useful and warlike arts. But as he approached manhood he became filled with an unconquerable desire to regain his paternal inheritance. He therefore took leave of his kind friend and preceptor, and set out for Iolcus to demand from his uncle Pelias the kingdom which he had so unjustly usurped.
