Kazimir Malevich - famous avant-garde artist, art theorist, philosopher. His "Black Square" is one of the most famous and mysterious paintings in Russian painting. Malevich called this creation an icon of his time and for many years sought to put into words the meaning of his main work. The artist's articles and manifestos, written with enthusiasm and pathos, open the veil of secrecy over this and his other works, help to comprehend the basic principles of abstract art. Initially considering the pen as an auxiliary tool of his creative activity, Malevich was so carried away by the element of the word that he gave it no less inspiration than canvas and brush. His original texts, presented in this edition with the preservation of the author's style and usage, demonstrate the sharpness of mind and the depth of the artistic vision of the great painter.
