1812-1867 French Theodore Rousseau Galleries Rousseau's pictures are always grave in character, with an air of exquisite melancholy which is powerfully attractive to the lover of landscapes. They are well finished when they profess to be completed pictures, but Rousseau spent so long a time in working up his subjects that his absolutely completed works are comparatively few. He left many canvases with parts of the picture realized in. detail and with the remainder somewhat vague; and also a good number of sketches and water-color drawings. His pen work in monochrome on paper is rare; it is particularly searching in quality. There are a number of fine pictures by him in the Louvre, and the Wallace collection. contains one of his most important Barbizon pictures. There is also an example in the Ionides collection at the Victoria and Albert Museum.
