Medea—the daughter of a king who hopes to prevent Jason and his army of Argonauts from taking a golden ram—is a girl with magical powers. Medea falls in love with Jason and decides to help him win the golden ram, betraying her father. She helps Jason by giving him some magical herbs, then returns to Greece with him as his wife. There, she magically restores some youth to Jason’s elderly father Aeson. After this act of kindness, however, she starts to use her magical powers for evil. Pretending that she and Jason are divorced, she travels to Pelias’s kingdom and, on pretense of reviving his youth, tricks his daughters into helping her kill him. Medea then returns home, kills her children, and flies her chariot to Athens where she marries king Aegeus. When Aegeus’s son Theseus returns from war, Medea tries to murder him, but Aegeus stops her.
