Suprematism 1916-17, Krasnodar by Kasimir Malevich and the Golden Rectangle

Successive Golden Rectangles dividing a Golden Rectangle into squares (Self Portrait by Kasimir Malevich).

Kazimir Severinovich Malevich (February 23, 1878 - May 15, 1935) was a painter and art theoretician, pioneer of geometric abstract art and the originator of the Avant-garde Suprematist movement.

Geometric abstract art is a form of abstract art based on the use of geometric forms sometimes, though not always, placed in non-illusionistic space and combined into non-objective (non-representational) compositions.

Suprematism is an art movement focused on fundamental geometric forms (in particular the square and circle) which formed in Russia in 1915-1916.

A golden rectangle is a rectangle whose side lengths are in the golden ratio, one-to-phi, that is, approximately 1:1.618. A distinctive feature of this shape is that when a square section is removed, the remainder is another golden rectangle, that is, with the same proportions as the first. Square removal can be repeated infinitely, which leads to an approximation of the golden or Fibonacci spiral.
