The Iliad 11.280–285

So spake he, and the charioteer lashed the fair-maned horses towards the hollow ships, and nothing loath the pair sped onward. With foam were their breasts flecked, and with dust their bellies stained beneath them as they bore the wounded king forth from the battle. But when Hector saw Agamemnon departing, to Trojans and Lycians he called with a loud shout: Ye Trojans and Lycians and Dardanians that fight in close combat, be men, my friends, and bethink you of furious valour. Gone is the best of the men, and to me hath Zeus, son of Cronos granted great glory. Nay, drive your single-hooved horses straight towardsthe valiant Danaans, that ye may win the glory of victory.
