 In Euripides "Iphigenia in Aulis", Clytemnestra, Iphigenia's mother and Helen's sister, begs her husband to reconsider his decision, calling Helen a ""wicked woman"".Clytemnestra tries to warn Agamemnon that sacrificing Iphigenia for Helen's sake is, ""buying what we most detest with what we hold most dear"".Before the opening of hostilities, the Greeks dispatched a delegation to the Trojans under Odysseus and Menelaus; they endeavored without success to persuade Priam to hand Helen back.
