The article presents an analysis of the poem «Shaman’s Dream» (1910) by A. E. Kulakovsky (1877–1926). It is proved that ethnogenetic contexts are present not only in the images, actualizing issues and national ideas, but also in parts and components of the structure. The artistic function names (genre product code) and the plot composition (mythopoetics as the basis of imagery) are considered. The importance of the classic works in the history of the Yakut
literature is revealed in the comparative analysis of the main text and the poem list that was made before the poem was published. In the analysis of the epic poem special attention is paid to understanding the author's beginning which is important for the problem statement, the taxonomy of motives like the plot’s basis, identifying the protagonist’s functions. The genre beginning of the poem is based on the artistic unity of the big time and real space.
