As through deep glens rageth fierce fire on some parched mountain-side, and the deep forest burneth, and the wind driving it whirleth every way the flame, so raged he every way with his spear, as it had been a god, pressing hard on the men he slew; and the black earth ran with blood. For even as when one yoketh wide-browed bulls to tread white barley in a stablished threshing-floor, and quickly is it trodden out beneath the feet of the loud-lowing bulls, thus beneath great-hearted Achilles his whole-hooved horses trampled corpses and shields together; and with blood all the axletree below was sprinkled and the rims that ran around the car, for blood-drops from the horses’ hooves splashed them, and blood-drops from the tires of the wheels. But the son of Peleus pressed on to win him glory, flecking with gore his irresistible hands. BOOK XXI. How Achilles fought with the River, and chased the men of Troy within their gates. But when now they came unto the ford of the fair-flowing river, even eddying Xanthos, whom immortal Zeus begat, there sundering them he chased the one part to the plain toward the city, even where the Achaians were flying in affright the day before, when glorious Hector was in his fury—thither poured some in flight, and Hera spread before them thick mist to hinder them:—but half were pent into the deep-flowing silver eddied river, and fell therein with a mighty noise, and the steep channel sounded, and the banks around rang loudly; for with shouting they swam therein hither and thither whirled round the eddies. And as when at the rush of fire locusts take wing to fly unto a river, and the unwearying fire flameth forth on them with sudden onset, and they huddle in the water; so before Achilles was the stream of deep-eddying Xanthos filled with the roar and the throng of horses and men. Then the seed of Zeus left behind him his spear upon the bank, leant against tamarisk bushes, and leapt in, as it were a god, keeping his sword alone, and devised grim work at heart, and smote as he turned him every way about: and their groaning went up ghastly as they were stricken by the sword, and the water reddened with blood. As before a dolphin of huge maw fly other fish and fill the nooks of some fair-havened bay, in terror, for he devoureth amain whichsoever of them he may catch; so along the channels of that dread stream the Trojans crouched beneath the precipitous sides. And when his hands were weary of slaughter he chose twelve young men alive out of the river, an atonement for Patroklos, Menoitios’ son that was dead. These brought he forth amazed like fawns, and bound behind them their hands with well-cut thongs, which they themselves wore on their pliant doublets, and gave them to his comrades to lead down to the hollow ships. Then again he made his onset, athirst for slaying.
