‘Proun’ was essentially El Lissitzky’s exploration of the visual language of suprematism with spatial elements, utilizing shifting axes and multiple perspectives; both uncommon ideas in suprematism. Suprematism at the time was conducted almost exclusively in flat, 2D forms and shapes, and El Lissitzky, with a taste for architecture and other 3D concepts, tried to expand suprematism beyond this. His Proun works spanned over a half a decade and evolved from straightforward paintings and lithographs into fully three-dimensional installations. They would also lay the foundation for his later experiments in architecture and exhibition design. While the paintings were artistic in their own right, their use as a staging ground for his early architectonic ideas was significant. In these works, the basic elements of architecture – volume, mass, color, space and rhythm – were subjected to a fresh formulation in relation to the new suprematist ideals. Through his Prouns, utopian models for a new world were developed.
