A survey of the life and work of Alfred Sisley, one of the leading exponents of the Impressionist movement. The text examines how Sisley's painting life was devoted to the landscape. The author examines the tonal balance of such celebrated paintings as the snow-scenes of the Paris suburbs, views of the flooded Seine at Port-Marly and the colourful regattas on the Thames. The author recognizes that full recognition for the artist and his work only began after his relatively early death and argues that even now, his work is unjustifiably neglected. In studying Sisley's artistic development, the artist's English nationality, early career, struggle to earn a living, and secluded later years are examined.
