Meantime Achilles, having rushed forth to the field, plunged into the thick of the fight, eagerly seeking for Hector. But first he met Æneas, whom Apollo had urged to encounter him. Achilles warned the Trojan hero to withdraw from the battle.
"Once already," said he, "I forced you to flee before my spear, running fast down Ida's slopes. I counsel you now to retire, lest evil happen to you."
Æneas answered that he was not to be thus frightened, as if he were a beardless boy. "I am the son of the goddess Venus," said he, "and my father, Anchises, was descended from Jove himself. We are not here, however, to talk, but to fight, and words will not turn me from my purpose."
So saying, Æneas hurled his spear. It struck the shield of Achilles with a ringing sound, and passed through two of its folds.
Vulcan's skill
Fenced with five folds the disk,—the outer two
Of brass, the inner two of tin; between
Was one of gold, and there the brazen spear
Was stayed.
Bryant, Iliad, Book XX.
Achilles now cast his heavy javelin. Through the shield of Æneas it crashed, but, as the hero stooped to avoid it, the spear passed over his shoulder, and plunged deep into the earth. Then with sword in hand, the Myrmidonian chief rushed furiously upon Æneas. He would probably have slain him, had not Neptune interfered. But the ocean god spread a mist over the eyes of the Greek warrior, and carried Æneas away in safety to the rear of the battlefield. The Trojan prince was thus preserved because the Dardan race, to which he belonged, was beloved by Jupiter. Moreover it was decreed by the Fates that the son of Anchises should, in later times, rule over a Trojan people, and that his sons' sons should rule after him.
Having placed Æneas out of danger, Neptune removed the mist from the eyes of Achilles. The hero, on looking about him, was amazed at not seeing the foe with whom, only an instant before, he had been in fierce conflict. But he did not wait to think over this strange occurrence. Rushing into the midst of the Trojans, he smote down warrior after warrior, as they came within reach of his spear. Amongst them was Pol-y-doʹrus, the youngest son of Priam. His father had forbidden him to go into the battle, because he loved him most of all his sons. But Polydorus was a brave youth, and he wished to show his swiftness, for in speed of foot he excelled all the young men of Troy.
He ranged the field, until he lost his life.
Him with a javelin the swift-footed son
Of Peleus smote as he was hurrying by.
Bryant, Iliad, Book XX.
