Cubism  The most influential style of the twentieth century, developed in Paris by Picasso and Braque, beginning in 1907. The early mature phase of the style, called Analytical Cubism, lasted from 1909 through 1911. Cubism is based on the simultaneous presentation of multiple views, disintegration, and the geometric reconstruction of objects in flattened, ambiguous pictorial so space; figure and ground merge into one interwoven surface of shifting planes. Color is limited to neutrals. By 1912 the more decorative phase called Synthetic (or Collage) Cubism, began to appear; it was characterized by fewer, more solid forms, conceptual rather than observed subject matter, and richer color and texture.
