Zeus had not forgotten his promise to Thetis, and on the morning of the third day he summoned all the gods to council, and thus declared his will: "Hear me, all ye gods and goddesses, and let none dare to cross my purpose. I forbid any among you to take part in the battle to-day, and if any disobey me I will take him and fling him into Tartarus, the black and gloomy pit, as far beneath Hades as heaven is above the earth. Then shall ye learn how much mightier am I than ye all together." Without waiting for question or reply, the lord of Olympus mounted his car, and swept along his airy road until he came to the mountain-range of Ida, overlooking the Trojan plain. There he halted and took his station on Mount Gargarus, the highest peak of Ida, from which he had a complete view of Troy and the Grecian camp. Forth sallied the rival hosts, and soon the clash of arms rang through the cool morning air, as Greek grappled with Trojan in deadly conflict. All through the long hours, until noon, the issue remained doubtful; but when the sun stood at the zenith Zeus lifted a pair of golden scales, and weighed the fates of Greeks and Trojans; and the scale which held the fate of the Greeks sank down, heavy with defeat and disaster. Then Zeus thundered with a mighty peal from Ida, and hurled his bolt among the thronging ranks of the Greeks; and they were sore amazed, and pale Fear gat hold of them. Not one among them dared to stand his ground, neither Ajax, nor Idomeneus, nor Agamemnon himself. Only Nestor lagged behind, for he was hindered by the fall of one of his horses, which had been pierced through the brain by Paris with an arrow. Nestor sprang down, and began cutting through the traces with his sword; and while he was thus engaged, Hector came thundering past in hot pursuit of the Greeks, and seeing Nestor's plight turned aside to slay him. Diomede saw the old man's danger, and lashing his horses to a gallop drove instantly to his aid. "Mount, mount," he cried, "with me, and leave to my squires these sorry steeds of thine. Take thou the reins, and we will see if we can check the onset of the Trojans, and arrest Hector's destroying arm."
