There is evidence of Yesenin’s acquaintance with What is to be done? by Chernyshevsky, which happened during the adolescent years of the future poet, while he was studying at the Spas-Klepikovskaya second-class teacher’s school in 1909–1912. From the novel by a 19th century writer individual plot twists (the “living corpse” line), some stylistic fi ndings and the author’s judgments (about the mystery, the liar, Hamlet) seem to have migrated to the story of the 20th century poet, of course, in a veiled and transformed form.
