El Lissitzky had discovered a new way to look at various spatial systems that were already in place. In his work he also defined new spaces, which he referred to as Imaginary and Irrational. By fusing Suprematist ideas within Russian Constructivist practices of the time, he created his solution to spatial issues that he saw, called Suprematist Space. He explains these through the use of mathematics as a metaphor. An example use of this space is the Proun Room (Lissitzky, 1923). His explanation of his new systems against the previous systems in place was done only to create a legacy for himself and fulfil his ideal of becoming an Avant-Garde artist. His mathematical metaphors helped to logically explain the merit in current and new spatial ideas.
