Iphigenia auf Tauris (Iphigenia in Tauris) is a reworking by Johann Wolfgang von Goethe of the ancient Greek tragedy by Euripides. Goethe wrote the first version of his play in six weeks, and it was first performed on April 6, 1779, in prose form. He rewrote the final version in verse in 1786.
Goethe has rewritten Euripides's Iphigenia in Tauris into a rather amazing celebration of how one woman could heal the insanity and evils of the past, symbolized by the dysfunctional House of Atreus as well as by King Thoas. The kingdom was so inhospitable to strangers that they were in fact sacrificed on the altar.
In the tragedy, Iphigenia, daughter of Agamemnon, King of Mycenae, having for many years been kept against her will as Priestess in Diana's Temple at Tauris, is finally delivered and brought back to Greece by her brother Orestes and his friend, Pylades, chiefly by means of her own truthfulness.
