Passage: In addition to Seurat, the roots of cubism are to be found in the two distinct tendencies of Cezanne's later work: first his breaking of the painted surface into small multifaceted areas of paint, thereby emphasizing the plural viewpoint given by binocular vision, and second his interest in the simplification of natural forms into cylinders, spheres, and cones. However, the cubists explored this concept further than Cezanne. They represented all the surfaces of depicted objects in a single picture plane, as if the objects had all their faces visible at the same time. This new kind of depiction revolutionized the way objects could be visualized in painting and art.
Output:
Besides Seurat where else are the end of Cubism found?
