Abstract: The subject of the research is the analysis of the biographical myth in the creative writing of Vladimir Mayakovsky. The analysis of the biographical myth is one of the most important and least studied problems in contemporary literary studies. This article is also devoted to the theoretical analysis of this phenomenon. It is aimed at analysing the genesis and development of the biographical myth of Tolstoy in the creative writing of Vladimir Mayakovsky. The biographical myth of Tolstoy is a complex phenomenon of the Russian literature and culture of the XXth century represented differently by writers. In this research Kurianova applies methodological principles that were developed in the works devoted to supertext and its mythological basis. Lev Tolstoy is one of the most mythogenic personalities that was a legend when he was alive and after his death. The 'Tolstoy' myth was mythologized by many poets and writers of the XXth - XXIst centuries. In his creative writing Vladimir Mayakovsky mythologized Lev Tolstoy, his personality and his teaching but not his works or heroes.
