Cubism is a style of art developed in France in 1908 by Georges Braque and Pablo Picasso. It was one of the most important and influential movements of the twentieth century: many later modernist styles, such as futurism and orphism, derived from cubist principles. Early cubist works (c. 1908-12) combined multiple viewpoints of a subject in a single image. This "analytic cubism" was based on the artists' direct observation of a model from various angles. Later cubist works relied less on observation, resulting in a more directly inventive style called "synthetic cubism."
