knew most of the Parisian avant-garde, including Jean Metzinger, Albert Gleizes, Juan Gris, Pablo Picasso, Lugné-Poe and his theatrical circle, the poets Guillaume Apollinaire, Paul Fort, Max Jacob, and author Jules Romains. The sale of his work did not provide enough to live on and he depended on the generosity of patrons. Futurism He was invited by Filippo Tommaso Marinetti and Boccioni to join the Futurist movement and was a co-signatory, with Balla, Boccioni, Carlo Carrà, and Luigi Russolo, of the Manifesto of the Futurist Painters in February 1910 and the Technical Manifesto of Futurist Painting in April the same year. He was an important link between artists in France and Italy and came into contact with Cubism before his Futurist colleagues. Following a visit to Paris in 1911, the Italian Futurists adopted a sort of Cubism, which gave them a means of analysing energy in paintings and expressing dynamism. Severini helped to organize the first Futurist exhibition outside Italy at Galerie Bernheim-Jeune, Paris, in February 1912 and participated in subsequent Futurist shows in Europe and the United States. In 1913, he had solo exhibitions at the Marlborough Gallery, London, and Der Sturm, Berlin; it was during the show in London when he met and befriended British artist C. R. W. Nevinson, ultimately leading to the latter's decision to become a fellow Futurist. In his autobiography, written many years later, he records that the Futurists were pleased with the response to the exhibition at Galerie Bernheim-Jeune, but that influential critics, notably Apollinaire, mocked them for their pretensions, their ignorance of the main currents of modern art and their provincialism. Severini later came to agree with Apollinaire. Severini was less attracted to the subject of the machine than his fellow Futurists and frequently chose the form of the dancer to express Futurist theories of dynamism in art. He was particularly adept at rendering lively urban scenes, for example in Dynamic Hieroglyph of the Bal Tabarin (1912) and The Boulevard (1913). During the First World War he produced some of the finest Futurist war art, notably his Italian Lancers at a Gallop (1915) and Armoured Train (1915). He spent part of the war in Barcelona, but returned to Paris by July 1915. Crystal Cubism and Neo-classicism In 1916 Severini departed from Futurism and painted several works in a naturalistic style inspired by his interest in early Renaissance art. After the First World
