Venedikt Yerofeyev is a vivid and ambiguous phenomenon in Russian literature. His famous poem "Moscow — Petushki", written back in 1970, is a kind of philosophical parable, a work beyond time, because Yerofeyev created his own world in the book, his universe, in the center of which is "man as a meeting place for all planes of existence." First published on the pages of Sobriety and Culture magazine in 1988, the poem "Moscow — Petushki" became a true revelation for readers and was later translated into many languages of the world.In this edition, this masterpiece by Yerofeyev is published accompanied by detailed comments by Eduard Vlasov, which, like the poem itself, can rightfully be called the "encyclopedia of Soviet life." First published in 1998, Vlasov's comments have been republished several times since then. In them, readers will find not only explanations of many realities of the Soviet past, but also deciphers of hints, allusions and reminiscences, which are filled with the poem "Moscow — Petushki".
