This is one of those remarkable plays that feels like it was written just last week. Medea is the daughter of the evil King Aeetes in Colchis -- on the remote, eastern side of the Black Sea. She assists Jason in slaying the serpent that guarded the golden fleece, and fell deeply in love with him. (See Apollonius Rhodius' Argonautica for a fuller treatment of the love episode at Colchis). She even killed her brother, Absrytus, on their way back to Greece.
Medea has one problem, however. Aside from the fact she is a witch, she is a barbarian, a non-Greek. The Greeks used the word "barbaros" to refer to all people who weren't Greek, because if they didn't speak Greek, it just sounded like "bar bar bar" to the Greeks.
So after Jason and Medea settle in together back in Greece, his homeland, he decides that his interests (and Medea's) are better served if he marries the daughter of King Creon of Corinth. Medea gets jealous, poisons the woman, and then kills her two children in revenge.
Medea is an absolutely riveting character, whose tragic problems are those of all woman who have left their homes and families to follow men to foreign lands, only to be scorned by them in the end. The speeches of Jason and Medea are remarkable point-counterpoint presentations which reflect the deep influence of the sophists of Euripides' day. Medea sounds, at times, like a proto-feminist. She is one of the most enduring dramatic creations of all times, revealing with each line the remarkable genius of Euripides, the most modern of the three great Greek tragedians
