On the Banks of a River by Paul Cezanne. In this late, unfinished painting, Cézanne used blocks of color to construct the armature of a landscape. Likely working outdoors, he mapped the riverside village with squares and triangles and used parallel strokes of orange and brown to indicate a cargo-laden barge. A solid, curved structure at right marks a bend in the river, whose overlapping blue patches form a ribbon between the opposing banks. Lighter tones of blues and greens create mutual reflections in the water and the loosely drawn clouds. Cézanne’s working process is also evident in the roughly conceived foreground, where broad, multicolored patches indicate forms that he had not yet defined.
