Once upon a time, Medea and her husband Jason, had settled in Corinth, and lived a happy marital life along with their children. But after ten years, Jason became weary of being married to a sorceress and decided, to gain a more representative wife. Hence, he shifted his attention to Glauce, daughter of King Creon of Corinth.
This unfaithful behavior of Jason, tormented Medea, as she had never wronged him. She recollected how she had aided Jason to carry away the Golden Fleece, how she had murdered her own brother Apsyrtus, how she had destroyed Talos, how she married Jason in the cave of Macris, how she made old Aeson gain his youth, and how she had become the curse of King Pelias of Iolcus.
She thought that after all her aid, now, the ungrateful Jason had abandoned her for Glauce, and she seethed in this fire of Jason’s betrayal. With passing time, the ongoing frequent social meetings of Jason and Glauce, publicly compounded the humiliation of the already humiliated Medea. With a fake show of false joy, Medea, who was incensed wild with fury beyond endurance, pretended that she welcomed Glauce as the bride of Jason. To strengthen her forged display of love for Glauce, she sent her children to present Glauce, an expensive wedding gown as a gift.
But the heart of Medea was soaked in revenge, and the wedding gown was likewise, drenched in poison. As soon as Glauce wore it, her skin burned, and her body caught fire. Creon, the father of Glauce, attempted to rescue her, but he also burned. Both Glauce and Creon died, while the fire burned the palace. The extremely anguished Medea, with the aim of punishing Jason, discarded her motherly affection, and killed her own children, Mermerus and Pheres, whom Jason loved more than his own life. Then, Medea fled in her chariot of dragons, leaving behind Jason bereft of his wife, his children, and Glauce. Unable to bear the grief of his dead children, Jason killed himself.
