John Constable, an English landscape painter, painted many well-known works (A Cottage in a Cornfield, The Loch). He is the first landscape painter who considered that every painter should make his sketches directly from nature working in the open air. His technique and colouring are very close to the painting. Constable ignored the rules established by Reynolds. He insisted that art should be based on observation of nature and feeling. He was the herald of romanticism. But the realistic qualities of his art are sensed very strongly.
