A painter, in 1908 he was with Boccioni in Paris and in Germany. In Milan after the war, he turned to Futurism and then to Metaphysics. He was one of those who promoted a return to an elementary, archaising form of art with geometric impact, and he applied this to the theme of suburbs ("Urban Landscape", Jesi Collection). In 1922 he was one of the "Sette Pittori del Novecento", promoting a return to classicality and Italian art. In the 1930s he turned to murals, mosaics, decoration and architectural design. Shunned for his Fascist past, he returned to painting after the war, creating abstract works.
