Russian art movement founded by Mikhail F. Larionov (Larionov, Mikhail Fyodorovich), representing one of the first steps toward the development of abstract art in Russia. Larionov exhibited one of the first Rayonist works, Glass, in 1912 and wrote the movement's manifesto that same year (though it was not published until 1913). Explaining the new style, which was a synthesis of Cubism, Futurism, and Orphism, Larionov said that it “is concerned with spatial forms which are obtained through the crossing of reflected rays from various objects.”

The raylike lines appearing in the works of Larionov and Natalya Goncharova (Goncharova, Natalya) bear strong similarities to the lines of force in Futurist paintings. Rayonism apparently ended after 1914, when Larionov and Goncharova departed for Paris.
