Russian abstract-art movement developed about
1913 by Malevich. The Suprematist paintings
gradually became more severe, until in 1918
they reached a climax with the White on White
series showing white geometrical shapes on a
white ground. Suprematism was inspired in
part by Futurist and Cubist ideas. Early
paintings such as Black Square 1915 (Russian
Museum, Leningrad) used purely geometrical
shapes in bold dynamic compositions. The aims
of the movement were expressed by Malevich as
`the supremacy of pure feeling or perception
in the pictorial arts - the expression of
non-objectivity'.
