What is the work by Kazimir Malevich that was a scandalous pivot for abstract art?

The Black Square

"Black Square" by Kazimir Malevich, painted in 1915, is an icon of the Russian avant-garde and a milestone in abstract art. At its first exhibition, this minimalist work shocked audiences and critics, not only for its radical simplicity but also for what it symbolized: the total abandonment of representation in art. Malevich saw his work as the absolute zero of painting, a starting point for a new form of artistic expression freed from the constraints of the visible world. "Black Square" paved the way for the exploration of geometric abstraction and continues to be a source of inspiration and debate about the nature and purpose of art.
