The Channel at Gravelines, Petit-Fort-Philippe

Painted in 1890 and now at the Nelson-Atkins Museum of Art in Kansas City, this small panel study of the Gravelines channel near the Belgium-France border belongs to Seurat's final summer campaign. The Gravelines paintings of 1890 are among his most serene and geometrically resolved works, and the multiple panels and canvases from this campaign constitute a systematic investigation of the same flat, luminous coastal landscape under varying light conditions. The Nelson-Atkins panel captures the essential character of the subject with the efficiency of direct study, preparatory to the more fully developed final canvases.

The panel applies Seurat's divisionist system in the compact format of a field study: dots of colour are placed more rapidly and less uniformly than in the finished works, but the same systematic colour temperature logic governs the choice of adjacent hues across water, sky, and land zones.
