So when these twain had harnessed them in their dread armour, they set forth to go, and left there all the best of the host. And to them did Pallas Athene send forth an omen on the right, a heron hard by the way, and they beheld it not with their eyes, through the dark night, but they heard its shrill cry. And Odysseus was glad in the omen of the bird, and prayed to Athene: “Listen to me, thou child of aegis-bearing Zeus, that ever in all toils dost stand by me, nor doth any motion of mine escape thee: but now again above all be thou friendly to me, Athene, and grant that we come back with renown to the ships, having wrought a great work, that shall be sorrow to the Trojans.” Next again prayed Diomedes of the loud war-cry: “Listen now likewise to me, thou child of Zeus, unwearied maiden, and follow with me as when with my father thou didst follow, even noble Tydeus, into Thebes, when he went forth as a messenger from the Achaians. And them he left by the Asopos, the mail-clad Achaians, and a honeyed word he bare to the Kadmeians in that place; but on his backward way he devised right terrible deeds, with thee, fair goddess, for eager didst thou stand by him. Even so now stand thou by me willingly, and protect me. And to thee will I sacrifice a yearling heifer, broad of brow, unbroken, that never yet hath man led below the yoke. Her will I sacrifice to thee, and gild her horns with gold.” So spake they in their prayer, and Pallas Athene heard them. And when they had prayed to the daughter of mighty Zeus, they went forth on their way, like two lions, through the dark night, amid the slaughter, amid the slain men, through the arms and the black blood. Nay, nor the stout-hearted Trojans did Hector suffer to sleep, but he called together all the best of them, all that were chiefs and leaders of the Trojans, them did he call together, and contrived a crafty counsel: “Who is there that would promise and perform for me this deed, for a great gift? yea his reward shall be sufficient. For I will give him a chariot, and two horses of arching neck, the best that be at the swift ships of the Achaians, to whosoever shall dare the deed, and for himself shall win glory. And the deed is this; to go near the swift-faring ships, and seek out whether the swift ships are guarded, as of old, or whether already, being subdued beneath our hands, the foes are devising of flight among themselves, and have no care to watch through the night, being fordone with dread weariness.”
