The phrase analytic cubism describes the early period of cubism, commonly considered to range from 1908 to 1912, characterised by a fragmentary appearance of multiple viewpoints and overlapping planes. Historians have tended to break cubism into two phases in an effort to distinguish the groundbreaking experiments made by Pablo Picasso, Georges Braque and Juan Gris when they were exponents of cubism. The early phase, usually considered to run from 1908-12, is called analytical cubism, and synthetic cubism is the second. Due to its systematic dissection of the subject, viewpoint bu viewpoint, it is called analytical cubism, resulting in a fragmentary picture of multiple perspectives and overlapping planes. A condensed palette of colours was another defining characteristic of analytical cubism, so the viewer was not distracted from the structure of the shape and the density of the image at the centre of the canvas.
