Cubism began in 1907 in Paris and was pioneered by Picasso and Braque. They developed analytic, synthetic, and hermetic phases of Cubism over time. Cubist works depicted objects from multiple perspectives and planes at once rather than a single viewpoint. Key characteristics included geometrization of forms, using color as local tones rather than realistically, and dissolving volumes. Later synthetic Cubism incorporated collage and real materials into paintings, influencing Dada and Futurism. Other major Cubists included Juan Gris, Robert Delaunay, Sonia Delaunay, and Fernand Léger.
