I actually found this poem in a horse book. I was on the  horse breed the Camargue when I saw this poem in the interesting facts.

            ...in a shroud of silence like the dead,
            I heard a sudden harmony of hooves,
            And, turning, saw afar
            A hundred snowy horses unconfined,
            The silver runaways of Neptune's car
            Racing, spray-curled, like waves before the wind.
            Sons of the Mistral, fleet
            As him with whose strong gusts they love to flee,
            Who shod the flying thunders of their feet
            And plumed them with the snortings of
                   the sea.
