Olympias, the mother of Alexander the Great and a princess of the primitive land of Epirus, had the reputation of a snake-handler, and it was in serpent form that Zeus was said to have fathered Alexander upon her. Aeëtes, the king of Colchis and father of the sorceress Medea, possessed the Golden Fleece. He guarded it with a massive serpent that never slept. Medea, who had fallen in love with Jason of the Argonauts, enchanted it to sleep so Jason could seize the Fleece. (See Lamia).
