Iphigenia at Delphi.

    After escaping from Tauris, Iphigenia, her brother Orestes, and his friend Pylades went to Delphi. There, Iphigenia was mistaken for a Taurian by her long-lost sister, Electra. Thinking that Orestes had been murdered in Tauris, Electra tried to kill (or blind) Iphigenia, who was saved only by Orestes’ last-minute intercession. Iphigenia then became a priestess at Delphi and Electra married Pylades.
