There is nothing more invisible, nobler, and more beautiful in the vast world than the high mountain sun in winter. Reflected by snow, ice, and stone, light and warmth play indulgently in the indescribably clear winter air - a light and a radiance of fine, delicate, dry warmth that the lowlands have no idea about, even on the brightest days. The beauty of the crystal-clear winter has been captured by Hermann Hesse in a multitude of poems and thoughts that tell of the silence of a snowy landscape and the sunlit air in February.
