Medea is an ancient Greek tragedy written by Euripides, based upon the myth of Jason and Medea and first produced in 431 BC. The plot centers on the actions of Medea, a former princess of the "barbarian" kingdom of Colchis, and the wife of Jason; she finds her position in the Greek world threatened as Jason leaves her for a Greek princess of Corinth. Medea takes vengeance on Jason by murdering Jason’s new wife as well as her own children (two sons), after which she escapes to Athens to start a new life.
