Seneca's Medea is a Roman rewriting of Euripides' play, the same story with the same title, and the Greek version is the one every later Medea descends from. The plot is unchanged: Jason abandons Medea for a royal marriage, she destroys the bride and then kills their children. What Seneca changes is the register. Euripides gives Medea long arguments with a chorus that is asked to judge her; Seneca gives her rhetoric, incantation and violence described in detail, and has the children killed on stage rather than reported from off it. The Roman version is the one Renaissance Europe read first, which is how the Greek play reached later drama.
