Post-Impressionist painter Paul Signac left his architectural career for a vocation as an artist, befriending Georges Seurat and Claude Monet, and becoming an enthusiastic adherent of Pointillism and Divisionism, the application of pure color points to the canvas intended to merge in the viewer’s eye into a different hue. Signac’s “Venice” is a pointillist piece par excellence, abstract and sparse. A Mixed-Media Painting.
