Cubism Cubism", (from 1909 to 1914) during which time Juan Gris emerged as an important exponent (after 1911); and finally Cooper referred to "Late Cubism" (from 1914 to 1921) 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 (from 1911) and Léger (to a lesser extent) 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. Georges Braque's 1908 "Houses at L’Estaque" (and related works) prompted the critic Louis

In the novel, André Gide's early works, especially "L'Immoraliste" (1902), pursue the problems of freedom and sensuality that symbolism had posed; Alain-Fournier's novel "Le Grand Meaulnes" is a deeply felt portrait of a nostalgic past. But radical experimentation was not appreciated by all literary and artistic circles in the early 20th century. Popular and bourgeois tastes were relatively conservative.
