The Iliad 12.16–30

Rhesus and Heptaporus and Caresus and Rhodius, and Granicus and Aesepus, and goodly Scamander, and Simois, by the banks whereof many shields of bull's-hide and many helms fell in the dust, and the race of men half-divine—of all these did Phoebus Apollo turn the mouths together, and for nine days' space he drave their flood against the wall; and Zeus rained ever continually, that the sooner he might whelm the wall in the salt sea. And the Shaker of Earth, bearing his trident in his hands, was himself the leader, and swept forth upon the waves all the foundations of beams and stones, that the Achaeans had laid with toil, and made all smooth along the strong stream of the Hellespont, and again covered the great beach with sand, when he had swept away the wall; and the rivers he turned back to flow in the channel, where aforetime they had been wont to pour their fair streams of water.
