Correspondence of Andrei Bely (Boris Nikolaevich Bugaev, 1880-1934) and Alexander Blok (1880-1921), covering 1903-1919, reflected not only the history of the relationship between luminaries of Russian symbolism, but also the main stages of the sovereign and intertwining paths of writers. It's a genuine novel in letters - confessional, intellectual and dramatic. Poets corresponded before they saw each other. Brought together the romance of Dawn, the cult of Eternal Femininity, inherited from Vladimir Solovyov. Faith, poetry, creative self-determination - everything was discussed in the epistolary dialogue. The confidential exchange of poems, the course of philosophical reflections, literary intentions and publications, the "malice of the day," the story of travel, all form an unintentional plot of the Correspondence. At the epicenter - an explosion of passions: unheard of drama overflows letters in the midst of the Mystery of love experienced by the poets in reality. The heroine is the wife of Alexander Blok - Lyubov Dmitrievna Blok (nee Mendeleeva, 1881-1939). Psychological collision almost incinerated spiritual intimacy. But Alexander Blok and Andrei Bely - "children of the terrible years of Russia," "brothers," and neither personal strife, nor war and revolution - could separate the poets. Evidence - long-term Correspondence.
