The Iliad 3.292–297

Then they drew wine from the bowl into the cups, and poured it forth, and made prayer to the gods that are for ever. And thus would one of the Achaeans and Trojans say: Zeus, most glorious, most great, and ye other immortal gods, which host soever of the twain shall be first to work harm in defiance of the oaths,may their brains be thus poured forth upon the ground even as this wine, theirs and their children's; and may their wives be made slaves to others.
