Sergei Esenin (yihs-YAYN-yihn) wrote little besides poetry. Some autobiographical introductions and a few revealing letters are helpful in analyzing his poetry. The short story “Bobyl i druzhok” and the tale “Yar” are rarely mentioned in critical discussion of Esenin’s work, but his theoretical treatise “Kliuchi Marii” (1918; the keys of Mary) helps to explain his early revolutionary lyrics. This economically written, perceptive study traces the religious origins of various aspects of ancient Russian culture and art.
