A lesson from the classics

Hector was first to speak. "I will-no longer fly you, son of Peleus," said he, "as I have been doing hitherto. Three times have I fled round the mighty city of Priam, without daring to withstand you, but now, let me either slay or be slain, for I am in the mind to face you. Let us, then, give pledges to one another by our gods, who are the fittest witnesses and guardians of all covenants; let it be agreed between us that if Jove vouchsafes me the longer stay and I take your life, I am not to treat your dead body in any unseemly fashion, but when I have stripped you of your armour, I am to give up your body to the Achaeans. And do you likewise."

Achilles glared at him and answered, "Fool, prate not to me about covenants. There can be no covenants between men and lions, wolves and lambs can never be of one mind, but hate each other out and out an through. Therefore there can be no understanding between you and me, nor may there be any covenants between us, till one or other shall fall and glut grim Mars with his life's blood."
