In 1915, Kazimir Malevich (1878-1935) changed the future of modern art when his experiments in painting led the Russian avant-garde into pure abstraction. He called his innovation Suprematism - an art of pure geometric form meant to be universally comprehensible regardless of cultural or ethnic origin. This exhibition catalogue features nearly 120 paintings, drawings and objects, among them several rediscovered masterworks. In addition, the book includes previously unpublished letters, essays and diaries, along with contributions by international scholars who shed new light on this popular figure and his devotion to the spiritual in art.
