'Ambroise Vollard', 1915 (oil on canvas)

Cubism was invented around 1907 in Paris by Pablo Picasso and Georges Braque. It was the first abstract style of modern art. Cubist paintings ignore the traditions of perspective drawing and show you many views of a subject at one time. The Cubists believed that the traditions of Western art had become exhausted and to revitalize their work, they drew on the expressive energy of art from other cultures, particularly African art.
There are two distinct phases of the Cubist style: Analytical Cubism (pre 1912) and Synthetic Cubism (post 1912). Cubism influenced many other styles of modern art including Expressionism, Futurism, Orphism, Vorticism, Suprematism, Constructivism and De Stijl. Other notable artists associated with Cubism were Juan Gris, Fernand Leger, Robert Delaunay, Albert Gleizes, Jean Metzinger, Louis Marcoussis and Marie Laurencin.
