A study of clouds and trees, c1821, Constable, watercolour sketchbook study with pencilled under drawing, 168 x 253 mm., UK. " It becomes obvious that it was the days of rough or stormy weather that Constable preferred. Most of these studies are painted in oil on paper; this watercolour is perhaps an experiment, to try and introduce an even greater luminosity to the sky ...a kind of weather diary. More importantly, they aided Constable's main objective, to express emotion through landscape."
