Kazimir Malevich (1878-1935) is famous for Suprematism, an artistic movement introduced by the artist, and Black Square.

Malevich painted at least four Squares in the same technique (oil on canvas) between 1915 and the early 1930’s. They differ from each other not only in date of creation, but also in colour, the way they are drawn, and texture.

He painted his first Black Square in 1915. The artist reported that he could not sleep, eat, or drink for an entire week after he finished the painting, because he felt that Black Square was a breakthrough and a milestone in his artistic career as well as in the history of art in general.

Malevich first showed his painting in the 1915 show 0.10. The Last Futurist Exhibition of Paintings. Black Square was mounted in an upper corner of the gallery, diagonally connecting two walls. This was the position occupied by an icon in Russia: not hung on a wall or propped on a shelf, but in an upper corner.
