Book I
.
Thetis did not forget her promise. On the twelfth day, at the dawn of morning, she emerged from beneath the waves, and went up to Olympus. There she threw herself at the feet of Jupiter, as he sat on the summit of the mount apart from the other gods, and earnestly prayed him to grant victory to the Trojans until the Greeks should make amends to her son for the injury that had been done him.
Now it may seem that it was not just to ask that the whole Greek army should be punished for the act of their general. But the other chiefs and their people were hardly less to blame than Agamemnon, for they did not try to prevent him from doing the wrong. If they had opposed him very much, he would not perhaps have dared to insult their greatest warrior, the man without whose help they knew Troy could not be taken. Therefore Thetis begged Jupiter to punish all the Greeks by giving victory to the Trojans.
"O Jupiter, my father, if among The immortals I have ever given thee aid By word or act, deny not my request. Honor my son whose life is doomed to end So soon; for Agamemnon, king of men, Hath done him shameful wrong: he takes from him And keeps the prize he won in war. But thou, Olympian Jupiter, supremely wise, Honor him thou, and give the Trojan host The victory, until the humbled Greeks Heap large increase of honors on my son."
