Hailed as a brilliant theoretician, Voldemars Matvejs (best known by his pen name Vladimir Markov) was a Latvian artist who spearheaded the Union of Youth, a dynamic group championing artistic change in Russia, 1910-14. His work had a formative impact on Malevich, Tatlin, and the Constructivists before it was censored during the era of Soviet realism. This volume introduces Markov as an innovative and pioneering art photographer and assembles for the first time five of his most important essays. The translations of these hard-to-find texts are fresh, unabridged, and authentically poetic.
