Abstract: Fragments of the text that represent the category of space in the Old Russian hagiographies from the Uspensky Collection became the sources for this research. The object this article is the contexts that depict spatial images in dynamics. The subject is the semantics of the analyzed contexts. The relevance of the selected topic is substantiated by undiminishing interest to the interpretation of the category of space in the Old Russian texts, as by elaboration of the concept of sanctity in studying the hagiographic literature. The goal of this research lies in determination and description of the semantics of spatial transformations in the analyzed hagiographic texts. Research methodology leans on the descriptive method, which includes observation, interpretation and classification; as well as hermeneutical analysis with consideration of anthropological and axiological approaches. The scientific novelty consists in revealing the new aspect of the category of space in the hagiographic texts – spatial transformations. The author highlights several groups that characterize space transformations in the hagiographies: semantics of construction, semantics of destruction, semantics of expansion, semantics of transfiguration, and semantics of the miraculous. The keynote in the hagiographies is the idea of sanctity, which is important for the interpretation of the transforming space. All changes in the physical world take place under the influence of divine intervention for asserting sanctity of the hero or sanctity of the place. The depicted in the hagiographies spiritual reality impact the state of visible spatial images. In addition to the idea of sanctity, the perception of space transformations is affected by pragmatics of the text – the edifying focus of the genre. The acquired results can be valuable in studying the corpus of hagiographic texts from perspective of the category of space.
