The symbolism of fire and its cult results from its connection with the sun, the similarity of energy, and the use of both the element and star. Fire and sun are important elements in Slavic mythology and are central figures in myths. They could be symbols and components of a rituals. In traditional communities, they formed the basis for constructing an understanding of the world, particularly the magical world, where daily and sacred life revolves around certain constants and unchanging values. Fire and sun can be examples of such archetypes, which, when utilized "in practice," acquire the status of ritual actions. Despite changes in age, ideology and religion, fire and sun are still present in rituals and magical practices. In this presentation, I wanted to raise the issue of perceiving fire and sun through their use as attributes of deities and in ritual and magical activities in the ancient Slavic lands based on written, archaeological and linguistic sources.
