Experience of death is an event that by its own nature is beyond the human understanding of physical reality, and it is seen as a supernatural one, which cannot be fully explained by rational thought. In this article, I will investigate the figure of Marzanna/Mara/Morena, in Slavic folklore and popular mythology. Her figure it is associated with forces of the death and seasons chancing rituals. This complex of rites and supernatural spirits is discussed by Afanasyev, and it has as a relevant position in the ethnolinguistics. The investigation of Marzanna is seen as a theoretical tool in order to better understand phraseology of Slavic languages and his relationship with pan-European folklore’s depiction of death.
