Iphigenia in Tauris

"The Iphigenia in Tauris is not in the modern sense a tragedy; it is a romantic play, beginning in a tragic atmosphere and moving through perils and escapes to a happy end. To the archaeologist the cause of this lies in the ritual on which the play is based. All Greek tragedies that we know have as their nucleus something which the Greeks called an Aition-a cause or origin. They all explain some ritual or observance or commemorate some great event." So begins the preface to «Iphigenia in Tauris» by Euripides as translated and prefaced by Gilbert Murray.
