An abstract art movement that developed in Russia between 1910 and 1914. Founded and named by Mikhail Larionov and Natalia Goncharova, it was one of Russia’s first avant-garde art movements. Larionov and Goncharova published a Rayonist manifesto in 1913. As Larionov described it, Rayonism was “the painting of space revealed not by the contours of objects, not even by their formal colorings, but by the ceaseless and intense drama of the rays that constitute the unity of all things.” Rayonism ended with the start of the World War I.
