THE PROBLEM OF GENESIS OF THE YAKUT HEROIC EPOS OLONKHO IN THE WORKS OF RESEARCHERS

. The work is devoted to the problem of the origin of the Yakut olonkho in the works of researchers. The relevance of the study lies in the systematization and periodization of various scientific hypotheses on this topic, not previously carried out. The author identifies the pre-revolutionary, Soviet, modern (post-Soviet) periods of the study of the genesis of the Yakut epic. The works of the Yakutologists V. L. Seroshevsky, P. A. Oyunsky, G. A. P. I. V. Pukhov, G. U. Ergis, N. V. V. M. E. S. V. N. Ivanov, well-known Russian folklorists V. Y. Propp, E. M. Meletinsky, V. M. Zhirmunsky are considered. We came to the conclusion that all scholars of the olonkho belong to the early types of the epic, reveal its connection with the epic of the Turkic-Mongolian peoples of Siberia, and connect the time of its occurrence with the ethnogenesis of the Yakuts. Given the uncertainty of the ethnogenesis of the Sakha people, it seems difficult to establish the dating, the stages of the formation of olonkho.
