And as Iphigenia was led into the camp she marveled greatly, for all who looked upon her were filled with pity, and cold fear touched the heart of the maiden as she passed through the silent and sorrowful host. The warriors were moved at the sight of her youth and innocence; but no man strove to save her from her fate, for without her death all their gathering together would be for naught. Within the tent of Agamemnon the stern seer Calchas awaited the destined victim. All was prepared for the sacrifice, and Agamemnon and Menelaus already stood by the altar. In haste was the maiden decked out--not for her bridal, but for her death. Then they led her forth into the sunshine again, and she looked round upon the hillside and the blue sea where lay the idle ships; and when she saw her father standing by the altar she would have cried out to him and begged for mercy, but those who led her laid their hands upon her mouth. The poor child tried to win from her father one pitying glance, but Agamemnon hid his face in his mantle; he could not look upon the face of the child who was to be slain to expiate his sin. So there was no help for the beautiful and innocent maiden, and she was led to her death. But so great was the ruth of the Greeks that no man save the stern Calchas dared witness the terrible deed; and because they could not bear to believe afterwards that the maiden had indeed been slain there upon the altar, the tale went forth that at the last moment Diana had laid a hart upon the altar and had borne the maiden safely away to Tauris. But in truth the cruel sacrifice was completed, and even as the flame leapt up on the altar the tree-tops swung and swayed, and ripples coursed over the glassy surface of the sea; the breeze for which the host had waited so long had been set free, and the warriors joyfully hoisted their sails and stood out of the harbor of Aulis on their way to the siege of Troy. But now was Diana well avenged for Agamemnon's profanation of her grove. For, from the innocent blood of Iphigenia, uprose an avenger, destined to follow King Agamemnon and all his family till the dark deed had been expiated. Long and grievous was the warfare before the walls of Troy; and it was not till the tenth year after his setting forth that tidings came that King Agamemnon was on his way home. All through those years his wife had nourished the hope of vengeance in her heart, both for the death of Iphigenia and for the falsehood that had made her send the maiden to the camp. So the king came home only to his grave. His wife received him with gracious words and with every sign of rejoicing; but ere night fell Agamemnon lay slain in his bath, where the dagger of Clytemnestra had smitten him down.
