extensive participation in the Parisian scene. Gleizes realized that his evolution towards 'purity' carried with it the risk of alienation from the 'mentality of the milieu', but he saw it as the sole means of arriving at a new type of art that could reach a mass audience (just as the French murals of the 11th and 12th centuries). In Du Cubisme et les moyens de comprendre (1920), Gleizes went so far as to envisage the mass-production of painting; as a means of undermining the market system and thus the status of artworks as commodities. 'The multiplication of pictures,' Gleizes wrote, 'strikes at the heart of the understanding and the economic notions of the bourgeois.' 1920s–1930s After World War I, with the support given by the dealer Léonce Rosenberg, Cubism returned as a central issue for artists. With the Salons dominated by a return to classicism, Gleizes attempted to resuscitate the spirit of the Section d'Or in 1920 but was met with great difficulty, despite support by Fernand Léger, Alexander Archipenko, Georges Braque, Constantin Brâncuși, Henri Laurens, Jacques Villon, Raymond Duchamp-Villon, Louis Marcoussis and Léopold Survage. Gleizes' organizational efforts were directed towards the establishment of a European-wide movement of Cubist and abstract art in the form of a large traveling exhibition; the Exposition de la Section d’Or. The idea was to bring together a collection of works that revealed the complete process of transformation and renewal that had taken place. It was not the success he had hoped for. Cubism was seen as passé for emerging artists and other established artists such as Marcel Duchamp and Picabia, although Gleizes, on the contrary, felt that only its preliminary phase had been investigated. In addition to Cubists works (which already represented a wide variety of styles), the second edition of the Section d'Or held at the Galerie La Boétie from 5 March 1920 included De Stijl, Bauhaus, Constructivism and Futurism. It was the revival of the Section d'Or which ensured that Cubism in general would become Dada's preferred target. The new polemic resulted in the publication of Du cubisme et des moyens de le comprendre by Gleizes, followed in 1922 by La Peinture et ses lois. Following the death of Jules Roche, the Gleizes' had enough independent income and real estate to pursue their goals without bowing to material considerations, unlike many other artists. The Gleizes' spent more and more time at
