Myths of the Norsemen: From the Eddas and Sagas

As the Valkyrs’ steeds were personifications of the clouds, it was natural to fancy that the hoar frost and dew dropped down upon earth from their glittering manes as they rapidly dashed to and fro through the air. They were therefore held in high honour and regard, for the people ascribed to their beneficent influence much of the fruitfulness of the earth, the sweetness of dale and mountain-slope, the glory of the pines, and the nourishment of the meadow-land.
