The subject of this research is the concept of heroism (bogatyrs) as an element of Russian epic mentality. The focus of attention is the peculiarities of epic understanding of bogatyr power that excludes the interpretation by an epic bard of “his” character as a giant. Meanwhile, the popular in science representation of particular characters of the Russian Epos (Svyatogor, Mikula Selyaninovich, Ilya Muromets) as giants is caused by their idealization, convergence of an epic with a tale or myth, as well as readiness to proliferate upon epics such laws of poetics that are considered universal from the perspective of ethnographic theory and strive of the scholars of mythological school to distinguish in epic heroes the characters of the ancient religious systems. Based on the analysis of epic records, the author demonstrates that the bogatyrs are not giant, but rather look as regular people. Special attention is given to the adjustment of a receptive stereotype, associated with perception of the epic image of Svyatogor, caused by a distorted interpretation of this image by illustrators of the epics in the XIX century.
