Iphigenia is best known as the daughter Agamemnon, leader of the Greek forces at Troy, had to sacrifice in order to appease Artemis. Agamemnon ... offended Artemis, the virgin goddess of the hunt either by killing one of her sacred animals and/or by boasting immoderately that his hunting skill exceeded even that of Artemis. Artemis sent a contrary wind, which held the Greek fleet in the bay of Aulis, where it had assembled before sailing to Troy. The prophet Calchas divined that the daughter of Agamemnon would have to be sacrificed to atone for the offence. Agamemnon then summoned Iphigenia from home under the ruse that she was to be married to Achilles.
