But when they had put to sea from Argos and arrived for the second time at Aulis, the fleet was windbound, and Calchas said that they could not sail unless the fairest of Agamemnon's daughters were presented as a sacrifice to Artemis; for the goddess was angry with Agamemnon, both because, on shooting a deer, he had said, Artemis herself could not (do it better), and because Atreus had not sacrificed to her the golden lamb.
On receipt of this oracle, Agamemnon sent Ulysses and Talthybius to Clytaemnestra and asked for Iphigenia, alleging a promise of his to give her to Achilles to wife in reward for his military service. So Clytaemnestra sent her, and Agamemnon set her beside the altar, and was about to slaughter her, when Artemis carried her off to the Taurians and appointed her to be her priestess, substituting a deer for her at the altar; but some say that Artemis made her immortal.
