The subject of the author's considerations is the content of religious beliefs and ideas about the world in the early Piast state until the adoption of Christianity, hypothetically reconstructed on the basis of analyses from the field of contrastive and corpus folkloristics. The author focuses on the process of transition from the pagan mythological image of the world to the Christian religious image of the world and attempts to answer the question: how could the bearers of traditional beliefs react to the content proclaimed by the clergy of the new religion and what changes did they force in their axiology, image of the world and worldview. The analysis is based on selected types of folkloristic mofifs (reconstructed Slavic mythology and the Bible were compared). The presentation refers to the term ultrahistory (formulated by G. Dumezil).
