Elementarism
Elementarism (also referred to as Counter-Composition) was an art theory formulated by Theo van Doesburg after 1923 as an extension and evolution of the De Stijl movement. De Stijl, co-founded by Van Doesburg, Piet Mondrian, and other artists, initially adopted Neoplasticism — a strict artistic framework characterized by geometric abstraction and equilibrium achieved through the use of horizontal and vertical lines. Elementarism was a loosening of the strictures of Neoplasticism by incorporating additional elements into the established aesthetic framework, thereby advancing the development of De Stijl by extending the means of expression.
