“Unknown Yesenin” is the third, revised and expanded edition of Valentina Pashinina’s book. We really did not know Yesenin as he appears on its pages. Many facts of the life of the great Russian poet were comprehended in a new way, the authorship of the “Message to the Evangelist Demyan” was proven, which was saved and preserved by the political prisoners of UkhtPechLag, among whom was Vasily Petrovich Nadezhdin, who gave the poem to the author of this book, for which he is given special thanks. Based on a wealth of factual material, both published and virtually unknown to a wide range of readers, B.C. Pashinina offers her view on many events in the poet’s life, as well as the circumstances of his tragic death. For the first time, the biography of Sergei Yesenin is unfolded against the dynamic background of Russian history, and is not limited to the cramped walls of the scandalous cafe “Pegasus Stable”. The book is intended for a wide range of readers, it represents an undoubted interest for those who are deeply interested in the work and fate of Russia’s favorite poet.
