On this Iris fleet as the wind went forth to carry his message. Down she plunged into the dark sea midway between Samos and rocky Imbrus; the waters hissed as they closed over her, and she sank into the bottom as the lead at the end of an ox-horn, that is sped to carry death to fishes. She found Thetis sitting in a great cave with the other sea-goddesses gathered round her; there she sat in the midst of them weeping for her noble son who was to fall far from his own land, on the rich plains of Troy. Iris went up to her and said, "Rise Thetis; Jove, whose counsels fail not, bids you come to him." And Thetis answered, "Why does the mighty god so bid me? I am in great grief, and shrink from going in and out among the immortals. Still, I will go, and the word that he may speak shall not be spoken in vain."
The goddess took her dark veil, than which there can be no robe more sombre, and went forth with fleet Iris leading the way before her. The waves of the sea opened them a path, and when they reached the shore they flew up into the heavens, where they found the all-seeing son of Saturn with the blessed gods that live for ever assembled near him. Minerva gave up her seat to her, and she sat down by the side of father Jove. Juno then placed a fair golden cup in her hand, and spoke to her in words of comfort, whereon Thetis drank and gave her back the cup; and the sire of gods and men was the first to speak.
"So, goddess," said he, "for all your sorrow, and the grief that I well know reigns ever in your heart, you have come hither to Olympus, and I will tell you why I have sent for you. This nine days past the immortals have been quarrelling about Achilles waster of cities and the body of Hector. The gods would have Mercury slayer of Argus steal the body, but in furtherance of our peace and amity henceforward, I will concede such honour to your son as I will now tell you. Go, then, to the host and lay these commands upon him; say that the gods are angry with him, and that I am myself more angry than them all, in that he keeps Hector at the ships and will not give him up. He may thus fear me and let the body go. At the same time I will send Iris to great Priam to bid him go to the ships of the Achaeans, and ransom his son, taking with him such gifts for Achilles as may give him satisfaction."
Silver-footed Thetis did as the god had told her, and forthwith down she darted from the topmost summits of Olympus. She went to her son's tents where she found him grieving bitterly, while his trusty comrades round him were busy preparing their morning meal, for which they had killed a great woolly sheep. His mother sat down beside him and caressed him with her hand saying, "My son, how long will you keep on thus grieving and making moan? You are gnawing at your own heart, and think neither of food nor of woman's embraces; and yet these too were well, for you have no long time to live, and death with the strong hand of fate are already close beside you. Now, therefore, heed what I say, for I come as a messenger from Jove; he says that the gods are angry with you, and himself more angry than them all, in that you keep Hector at the ships and will not give him up. Therefore let him go, and accept a ransom for his body."
And Achilles answered, "So be it. If Olympian Jove of his own motion thus commands me, let him that brings the ransom bear the body away."
