Protagonist of the play, Medea's homeland is Colchis, an island in the Black Sea, which the Greeks considered the edge of the earth--a territory of barbarians. A sorceress and a princess, she used her powers and influence to help Jason secure the Golden Fleece; then, having fallen in love with him, she fled her country and family to live with Jason in Iolcus, his own home. During the escape across the Mediterranean, she killed her brother and dumped him overboard, so that her pursuers would have to slow down and bury him. While in Iolcus, she again used her devilish cleverness to manipulate the daughters of the local king and rival, Pelias, into murdering their own father. Exiled as murderers, Jason and Medea settled in Corinth, the setting of Euripides' play, where they established a family of two children and gained a favorable reputation. All this precedes the action of the play, which opens with Jason having divorced Medea and taken up with a new family. The play charts Medea's emotional transformation, a progression from suicidal despair to sadistic fury. She eventually avenges Jason's betrayal with a series of murders, concluding with the deaths of her own children. Famously, the pleasure of watching Jason suffer their loss outweighed her own remorse at killing them.Jason can be considered the play's villain, though his evil stems more from weakness than strength. A former adventurer, he abandons his wife, Medea, in order to marry Glauce, the beautiful young daughter of Creon, King of Corinth. Hoping to advance his station through this second marriage, he only fuels Medea to a revenge that includes the deaths of his new bride, her father, and his children. Jason's tactless self-interest and whiny rationalizations of his own actions make him a weak, unsympathetic character.
