Abstract: The purpose of this study is to identify the features of the poetics of G.D. Grebenshchikov's novel "The Epic of Mikul Buyanovich", written during the years of emigration. The first edition of the novel took place in 1924. The article reflects the reception of critics of the Russian diaspora to this publication and to the authorized translation of 1940, which was published in the USA. The main hypothesis is that this novel can be correlated with Russian ornamental prose at the genre-style level, they are brought together by epic stylization, plot fragmentation, a large role of individual motifs when the text unfolds in the system of intertextual relations reflecting the mythologized worldview of the author.    Ornamental prose is an artistic and stylistic kind of verbal skill that combines the features of prose and poetry, therefore, linguopoetic and contextual analysis is used in the work. Taking into account that ornamental prose is a concept that is not correlated with a specific style, and ornamental fields are constantly modified depending on the author's artistic method, conclusions are drawn about the main stylistic "keys" and genre transformations of G.D. Grebenshchikov's novel "The Epic of Mikul Buyanovich". The renewal of the artistic language in the first half of the XX century was a characteristic phenomenon not only for modernist literary trends, but also for traditionalism, with which the aesthetic attitudes and artistic practice of G.D. Grebenshchikov can be correlated.
