Abstract: This scientific article is devoted to the study of the influence of mystical motifs and images of the Middle Ages on the work of the Russian poet Nikolai Gumilev. The central task of the study is to analyze the specific works of the poet, in which the influence of mystical themes is most clearly traced. The article draws attention to various aspects of the interaction of mysticism and creativity, including structure, rhythm, language and images in Gumilev's works. The article uses methods of comparative analysis, textual interpretation and cultural and historical contextualization. Particular attention is paid to the reception of mystical elements in Gumilev's work among his contemporaries and critics, such as Marina Tsvetaeva and Anna Akhmatova. One of the conclusions of the study is that mystical motifs and images not only enrich Gumilev's creative world, but also serve as a key factor in the formation of his unique style. This, in turn, allows us to consider him one of the most significant and interesting authors of Russian literature of the early XX century. The novelty of the study is a detailed analysis of mystical elements in the context of Gumilev's general style and aesthetic principles, which was not previously considered in such completeness. These results may be useful for further study of the influence of mystical themes on Russian literature in general and on Gumilev's work in particular.
