1923
El Lissitzky called his mind-bending geometric works 'Prouns,' essentially blueprints for a new reality. In this 1923 piece titled Sentry, floating cubes, sharp triangles, and rectangles assemble into a watchful, almost robotic figure with a single unblinking eye perched on top. It’s a fantastic example of the Constructivist movement, where artists believed art should be as functional and industrial as a machine. The composition feels like it’s defying gravity, balancing precariously on thin lines as if ready to march right off the page into a futuristic city.
