The Medea of Euripides
All through the voyage home, a world-wide baffled voyage by the Ister and the Eridanus and the African Syrtes, Medea was Still in her element, and proved a constant help and counsellor to the Argonauts. When they reached Jason's home, where Pelias was Still king, things began to be different. An ordered and law-abiding Greek state was scarcely the place for the untamed Colchian. We only know the catastrophe. She saw with smothered rage how Pelias hated Jason and was bent on keeping the kingdom from him, and she determined to do her lover another act of splendid service. Making the most of her fame as an enchantress, she persuaded Pelias that he could, by a certain process, regain his youth. He eagerly caught at the hope. His daughters tried the process upon him, and Pelias died in agony. Surely Jason would be grateful now!
