The Iliad 11.823–836

For verily all they that aforetime were bravest, lie among the ships smitten by darts or wounded with spear-thrusts at the hands of the Trojans, whose strength ever waxeth. But me do thou succour, and lead me to my black ship, and cut the arrow from my thigh, and wash the black blood from it with warm water, and sprinkle thereon kindly simples of healing power, whereof men say that thou hast learned from Achilles, whom Cheiron taught, the most righteous of the Centaurs. For the leeches, Podaleirius and Machaon, the one methinks lieth wounded amid the huts, having need himself of a goodly leech, and the other in the plain abideth the sharp battle of the Trojans.
