Helen (Ἑλένη, Helenē) is a drama by Euripides about Helen, first produced in 412 BC for the Dionysia in a trilogy that also contained Euripides' lost Andromeda. The play has much in common with Iphigenia in Tauris, which is believed to have been performed around the same time period. Helen was written soon after the Sicilian Expedition, in which Athens had suffered a massive defeat. Concurrently, the sophists – a movement of teachers who incorporated philosophy and rhetoric into their occupation – were beginning to question traditional values and religious beliefs. Within the play's framework, Euripides starkly condemns war, deeming it to be the root of all evil. About thirty years before this play, Herodotus argued in his Histories that Helen had never in fact arrived at Troy, but was in Egypt during the entire Trojan War. The Archaic lyric poet Stesichorus had made the same assertion in his "Palinode" (itself a correction to an earlier poem corroborating the traditional characterization that made Helen out to be a woman of ill repute). The play Helen tells a variant of this story, beginning under the premise that rather than running off to Troy with Paris, Helen was actually whisked away to Egypt by the gods. The Helen who escaped with Paris, betraying her husband and her country and initiating the ten-year conflict, was actually an eidolon, a phantom look-alike. After Paris was promised the most beautiful woman in the world by Aphrodite and he judged her fairer than her fellow goddesses Athena and Hera, Hera ordered Hermes to replace Helen, Paris' assumed prize, with a fake. Thus, the real Helen has been languishing in Egypt for years, while the Greeks and Trojans alike curse her for her supposed infidelity. In Egypt, king Proteus, who had protected Helen, has died. His son Theoclymenus, the new king with a penchant for killing Greeks, intends to marry Helen, who after all these years remains loyal to her husband Menelaus.
