Cubism
Cubism is an expression that used to designate a well known, distinguished and foundational artistic stream with respect to many other currents and movements that would subsequently be developed. However, Cubism is not a movement headed by a founder and does not have a unitary direction. The term "cubism" is occasional: in 1908, Matisse observed some Braque compositions of "small cubes" judged them negatively, and Louis Vauxcelles called them "cubist bizarre" the following year. Since then Picasso, Braque and others have been called Cubist. However, one can find in Paul Cézanne, a painter who in his solitary experiments was able to prefigure those that will be the style, vision and Cubist themes. In addition to them, Guillaume Apollinaire, Robert Delaunay, Marcel Duchamp, his brother Raymond Duchamp-Villon, Jacques Villon, Francis Picabia, Gino Severini. Other important authors of the period were Albert Gleizes, Jean Metzinger, Marie Laurencin, Max Weber, Louis Marcoussis, Roger de la Fresnaye, František Kupka, Léopold Survage and Félix Tobeen.
