When bathes the sun his burning crown, Within old Ostia's main, He sends transforming angels down Upon the Roman plain. Bright threads they fling of iris hue, And scatter crimson plumes, As if all nature to renew With showers of fiery blooms. See flashing out in golden grace A thousand arches rise, And bridge the violet depths of space To mountains of surprise. To mountain waves of amethyst, All flaming up carmine; Upon each crest the angels rest Who tend the sun's decline. But soon the subtle pomps of light Evade us like a dream, And with a breath the greys of night Envelop every gleam. The fires are dead, the gold is stone, The mountains, shadowy ghosts: Ah, whither are the angels gone With all their radiant hosts? They travel on from height to height, In splendour to diffuse The truth that earth's divinest light Hath no abiding hues. |
