This publication presents Kazimir Malevich’s theoretical legacy, which is first and foremost connected to the time he spent in Kyiv and in Ukraine. When he lived in Kyiv, he taught at the Kyiv Art Institute and published in the journals Nova Generatsiia [New Generation] and Avanhard [Avant-Garde]. In addition to these topics, the book also covers his letters, memoirs, and various publications related to his exhibition at the Kyiv Art Gallery in the 1930. Kazimir Malevich: The Kyiv Period is unique in that it includes not only the artist’s well-known publications, but also texts of his that were only discovered in 2015, when they were found in Kyiv in the archive of artist Marian Kropyvnytsky. In the late 1920s, Kropyvnytsky was Malevich’s personal assistant at the Kyiv Art Institute.
