Theophany is the manifestation of a deity, an act of revelation to the world. Traces of theophany (a visit or activity of the gods) are left in stone and dendromorphic features. Therefore, theophany is possible at any time, or at least at some point, for example, in the event of an accident or illness. Sites of theophany are visited in the hope of recovering or preserving health, to carry out therapeutic procedures, or perform ritual actions. This paper analyses data on stone and dendromorphic theophany in 15th to 18th-century written sources, and identifies reflections of it in 19th to 21st-century therapeutic methods of folk medicine, on the basis of archival records and the author’s records of healing beliefs.
