Cubism Painting. Cubism is an early-20th-century avant-garde art movement that revolutionized European painting and sculpture, and inspired related movements in music, literature and architecture. Cubism has been considered the most influential art movement of the 20th century. The term is broadly used in association with a wide variety of art produced in Paris or near Paris during the 1910s and throughout the 1920s. The movement was pioneered by Pablo Picasso and Georges Braque, joined by Jean Metzinger, Albert Gleizes, Robert Delaunay, Henri Le Fauconnier, and Fernand Léger. One primary influence that led to Cubism was the representation of three-dimensional form in the late works of Paul Cézanne. A retrospective of Cézanne's paintings had been held at the Salon d'Automne of 1904, current works were displayed at the 1905 and 1906 Salon d'Automne, followed by two commemorative retrospectives after his death in 1907. In Cubist artwork, objects are analyzed, broken up and reassembled in an abstracted form, instead of depicting objects from a single viewpoint, the artist depicts the subject from a multitude of viewpoints to represent the subject in a greater context. In France, offshoots of Cubism developed, including Orphism, Abstract art and later Purism. The impact of Cubism was far-reaching and wide-ranging. In other countries Futurism, Suprematism, Dada, Constructivism, De Stijl and Art Deco developed in response to Cubism. Early Futurist paintings hold in common with Cubism the fusing of the past and the present, the representation of different views of the subject pictured at the same time, also called multiple perspective, simultaneity or multiplicity, while Constructivism was influenced by Picasso's technique of constructing sculpture from separate elements. Other common threads between these disparate movements include the faceting or simplification of geometric forms, and the association of mechanization and modern life. Historians have divided the history of Cubism into phases. In one scheme, the first phase of Cubism, known as Analytic Cubism, a phrase coined by Juan Gris a posteriori, was both radical and influential as a short but highly significant art movement between 1910 and 1912 in France. A second phase, Synthetic Cubism, remained vital until around 1919, when the Surrealist movement gained popularity. English art historian Douglas Cooper proposed another scheme, describing three phases of Cubism in his book, The Cubist Epoch. According to Cooper there was Early Cubism, when the movement was initially developed in the studios of Picasso and Braque; the second phase being called High Cubism, during which time Juan Gris emerged as an important exponent; and finally Cooper referred to Late Cubism as the last phase of Cubism as a radical avant-garde movement. Douglas Cooper's restrictive use of these terms to distinguish the work of Braque, Picasso, Gris and Léger implied an intentional value judgement. Cubism burgeoned between 1907 and 1911. Pablo Picasso's 1907 painting Les Demoiselles d'Avignon has often been considered a proto-Cubist work. In 1908, in his review of Georges Braque's exhibition at Kahnweiler's gallery, the critic Louis Vauxcelles called Braque a daring man who despises form, reducing everything, places and a figures and houses, to geometric schemas, to cubes. Vauxcelles recounted how Matisse told him at the time, Braque has just sent in a painting made of little cubes. The critic Charles Morice relayed Matisse's words and spoke of Braque's little cubes. The motif of the viaduct at l'Estaque had inspired Braque to produce three paintings marked by the simplification of form and deconstruction of perspective. Georges Braque's 1908 Houses at L'Estaque prompted Vauxcelles, in Gil Blas, 25 March 1909, to refer to bizarreries cubiques. Gertrude Stein referred to landscapes made by Picasso in 1909, such as Reservoir at Horta de Ebro, as the first Cubist paintings. The first organized group exhibition by Cubists took place at the Salon des Indépendants in Paris during the spring of 1911 in a room called 'Salle 41'; it included works by Jean Metzinger, Albert Gleizes, Fernand Léger, Robert Delaunay and Henri Le Fauconnier, yet no works by Picasso or Braque were exhibited. By 1911 Picasso was recognized as the inventor of Cubism, while Braque's importance and precedence was argued later, with respect to his treatment of space, volume and mass in the L'Estaque landscapes.
