John Ruskin wrote: “The noblest scenes of the earth can be seen and known but by few… The sky is for all……It is fitted in all its functions for the perpetual comfort and exalting of the heart, for soothing it and purifying it from its dross and dust. Sometimes gentle, sometimes capricious, sometimes awful, never the same for two moments together; almost human in its passions, almost spiritual in its tenderness, almost divine in its infinity…….And yet we never tend to it, or make it a subject of thought.” (‘Modern Painters I: Of Truth of Skies’, 1843).
