Medea, one of Euripides' masterpieces, was put on in 431 BC, together with his Philoctetes, Dictys and The Reapers, but won only third prize, losing out to work by Euphorion and Sophocles. The Medea legend was well known to Greek audiences. After the voyage of the Argonaughts, and the dangers which love-smitten princess helped him escape, Jason married Medea and brought her to Iolchus and then Corinth. Here, though she had borne him two sons, Jason threw Medea over for Glauce, the daughter of Creon, King of Corinth. The repudiated wife plotted revenge, and, as the play opens, faces exile for speaking against the royal house.
