The Iliad 23.651–657

a mule of six years, unbroken, the which is hardest of all to break; and for him that should be worsted he appointed a two-handled cup. Then he stood up, and spake among the Argives, saying: Son of Atreus, and ye other well-greaved Achaeans, for these prizes we invite warriors twain, the best there are, to lift up their hands and box amain.Let him to whom Apollo shall grant strength to endure, and all the Achaeans have knowledge thereof, go his way to his hut leading the sturdy muIe; but he that is worsted shall bear as his prize the two-handled cup.
