Medea is an ancient Greek tragedy written by Euripides, based upon the myth of Jason and Medea and first produced in 431 BC. One of the most powerful and enduring of Greek tragedies, Medea centers on the myth of Jason, leader of the Argonauts, who has won the dragon-guarded treasure of the Golden Fleece with the help of the sorceress Medea. Having married Medea and fathered her two children, Jason abandons her for a more favorable match, never suspecting the terrible revenge she will take. Euripides makes Medea breach a fundamental taboo: the bond between mother and child, and the assumption of unconditional maternal love.
