John Constable (1776–1837) was an English Romantic painter, who is best known for his depictions of Dedham Vale, the area around his home. This sketch, titled Flatford Mill on the River Stour, is housed in London's National Gallery. It was painted in 1817 when Constable was 41—what some said was a mature age for a man to produce what may be called his first important work. It is a picture of England—ripe, lush, carefully composed, carefully executed, but fresh as are the meadows on the banks of the Stour. And the sky, across which the large clouds are drifting is sunny.
