The memoirs of A. B. Mariengof, V. G. Shershenevich and I. V. Gruzinov tell about the era of the 1910-1920s, when new literary movements and schools were born in polemical battles, in particular Imagism, whose representatives were authors. Among other things, "My Century, My Friends and Girlfriends" and "Roman Without Lies" by Mariengof, "Magnificent Eyewitness" by Shershenevich and "Mayakovsky and Literary Moscow" by Gruzinov are valuable in vivid portraits of V. Bryusov, S. Yesenin, V. Khlebnikov, V.Meyerhold, V. Mayakovsky and others.
