Abstract: The subject of the study is the analysis of the grotesque and fiction as artistic methods by which Konstantin Konstantinovich Sluchevsky transforms real loci in his early poetic works. Special attention is paid to the study of how Sluchevsky uses grotesque images and fantastic elements to create a unique poetic space that combines elements of reality and an imaginary world. The study analyzes key motifs such as life and death, eternity and the moment, as well as their intertwining in the spatial and temporal structures of poems. The research is aimed at revealing how the poet expresses his existential reflections through the grotesque and fiction, creating complex, multidimensional images and transforming everyday spaces into philosophical categories. The work uses an integrated approach that includes elements of structural and semiotic analysis of a literary text. The methodological basis of the research is the theory of the grotesque and fiction, as well as research in the field of space poetics. The novelty of the research lies in the fact that for the first time a detailed analysis of the use of the grotesque and fiction as key artistic methods in the poetic work of Konstantin Konstantinovich Sluchevsky is carried out. Unlike previous studies, where attention was paid to the general themes of his poetry, this study focuses on specific means of transforming real loci through which the poet creates a philosophically saturated and multi-layered poetic space. The author demonstrates that Sluchevsky's grotesque and fantasy are not just stylistic techniques, but full-fledged tools for rethinking such fundamental categories as life and death, being and non-being, eternity and transience. This study deepens the understanding of how Sluchevsky, through artistic means, forms a special poetic reality where the boundaries between the real and the fantastic are blurred, which allows the reader to immerse himself in existential reflections on the nature of human existence. This approach opens up new horizons for the study of his work and emphasizes the importance of these methods for understanding the deep philosophical aspects of the poet's lyrics.
