Sisley's student works are lost.
His first landscape paintings are sombre, coloured with dark browns, greens, and pale blues.
They were often executed at Marly and Saint-Cloud. Little is known about Sisley's relationship with the paintings of J. M. W. Turner and John Constable, which he may have seen in London, but some have suggested that these artists may have influenced his development as an Impressionist painter, as may have Gustave Courbet and Jean-Baptiste-Camille Corot.
