When I sit down to make a sketch from nature, the first thing I try to do is to forget that I have ever seen a picture. - John Constable

We must bear in recollection that the sentiment of the picture is that of solemnity, not gaiety & nothing garish, but the contrary — yet it must be bright, clear, alive fresh, and all the front seen.

My picture [A Boat Passing a Lock, 1823-6] is liked at the [Royal] Academy, indeed it forms a decided feature and its light can not be put out. Because it is the light of nature — the Mother of all that is valuable in poetry — painting or anything else... my execution annoys most of them and all the scholastic ones – perhaps the scarifies I make for 'lightness' and 'brightness' is too much but these things are the essence of Landscape.

The landscapes of Ruysdael present the greatest possible contrast to those of Claude, showing how powerfully, from the most opposite directions, genius may command our homage. In Claude's pictures, with scarcely an exception, the sun ever shines. Ruysdael, on the contrary, delighted in, and has made delightful to our eyes, those solemn days, peculiar to his country and to ours, when without storm, large rolling clouds scarcely permit a ray of sunlight to break the shades of the forest.
