Constable, John (1776-1837), ranks with J. M. W. Turner as the leading English landscape painter of the 1800's. Constable is known mainly for his paintings of the rural areas near his birthplace and in other parts of eastern England. Constable sketched outdoors during the warmer months. During the winter, he worked in his studio and developed the sketches into paintings. Constable emphasized such environmental features as the appearance of the sky and clouds, and the effects of light and shadow on the landscape. He believed such features in a painting reflected nature accurately. Constable's fresh style influenced the Impressionist painters of the late 1800's.
