Of rivers, all that from the Idaean heights Flow to the ocean⁠—Rhesus, Granicus, Heptaporus, Caresus, Rhodius, Aesepus, and Scamander’s hallowed stream, And Simoïs, in whose bed lay many shields And helms and bodies of slain demigods. Phoebus Apollo turned the mouths of these All toward one spot; nine days against the wall He bade their currents rush, while Jupiter Poured constant rain, that floods might overwhelm The rampart; and the god who shakes the earth, Wielding his trident, led the rivers on. He flung among the billows the huge beams And stones which, with hard toil, the Greeks had laid For the foundations. Thus he levelled all Beside the hurrying Hellespont, destroyed The bulwarks utterly, and overspread The long broad shore with sand; and then he brought Again the rivers to the ancient beds In which their gently flowing waters ran.
