Impression of a landscape.

"A mass of mountain seen against the light, may, at first, appear all of one blue; and so it is, blue as a whole, by comparison with other parts of the landscape. But look how that blue is made up. There are black shadows in it under the crags, there are green shadows along the turf, there are gray half-lights upon the rocks, there are faint touches of stealthy warmth and cautious light along their edges; every bush, every stone, every tuft of moss has its voice in the matter, and joins with individual character in the universal will."

Ruskin speaking of Turner in Modern Painters, Vol 1. We always had a copy floating round the house, I remember dipping into it, ever fascinated by what Ruskin had to say.
