Sisley's first works are lost. His earliest known work is "Lane near a Small Town". This is believed to have been painted around 1864. His first landscape paintings are sad and gloomy, coloured with dark browns, greens, and pale blues. They were often painted at Marly and Saint-Cloud. No one knows if Sisley's knew the paintings of J. M. W. Turner and John Constable, which he may have seen in London. These artists have been suggested as an influence on his development as an Impressionist painter, as well as Gustave Courbet and Jean-Baptiste-Camille Corot.
