In the month of July of the year 1348, between the feasts of St. Benedict and of St. Swithin, a strange thing came upon England, for out of the east there drifted a monstrous cloud, purple and piled, heavy with evil, climbing slowly up the hushed heaven. In the shadow of that strange cloud the leaves drooped in the trees, the birds ceased their calling, and the cattle and the sheep gathered cowering under the hedges. A gloom fell upon all the land, and men stood with their eyes upon the strange cloud and a heaviness upon their hearts. They crept into the churches where the trembling people were blessed and shriven by the trembling priests. Outside no bird flew, and there came no rustling from the woods, nor any of the homely sounds of Nature. All was still, and nothing moved, save only the great cloud which rolled up and onward, with fold on fold from the black horizon. To the west was the light summer sky, to the east this brooding cloud-bank, creeping ever slowly across, until the last thin blue gleam faded away and the whole vast sweep of the heavens was one great leaden arch.
