The book by Doctor of Philosophy V. N. Demin (1942–2006) is dedicated to one of the iconic figures of the Silver Age - Andrei Bely (1880–1934). An original poet, prose writer, critic, memoirist, he entered the cohort of outstanding figures of Russian culture and literature of the twentieth century. Andrei Bely left a noticeable mark in the history of Russian philosophy as a propagandist of the cosmist worldview, a theorist of symbolism and an adherent of anthroposophical teaching. His life was full of dramatic collisions. He experienced universal worship and targeted persecution, dizzying cosmic visions and sublime love for the five Muses, who inspired him to creative achievements. The author focuses on the chivalrous friendship of Andrei Bely with Alexander Blok, his relationships with Valery Bryusov, Dmitry Merezhkovsky, Zinaida Gippius, Maximilian Voloshin, Vyacheslav Ivanov, Maxim Gorky, Marina Tsvetaeva, Vsevolod Meyerhold and other leaders of the thoughts of the Russian intelligentsia.
