Was There Reading of Blok’s “Unknown Lady” in Vyacheslav Ivanov’s Tower?

The article is devoted to the history of creation of the poem “Unknown Lady,” written in by A. Blok April 1906 during the preparation for state exams at St. Petersburg University. Some parts of Vl. Piast’s memoirs and the correspondence of contemporaries reveal the first impressions of the poem in a narrow circle of friends. The article examines in detail Blok's reading of “Unknown Lady” in January 1907 at Blok's apartment with the presence of Vyach. Ivanov and his wife L.D. Zinovieva-Annibal, and the echo that the poem received in their work. The author of the article questions the version of Korney Chukovsky that this reading took place at the Ivanov’s Tower and that Chukovsky was personally present.
