This work by Vinogradov, carried out on the order of the State Academy of Material Culture, laid the foundation for the studying stone labyrinths on the Solovetsky Islands. The author was the first to formulate the main questions that have not yet received a final explanation: who had built those stone structures, why they had been built, and when. In the summer season of 1926, the author examined the Anzersky and Bolshoi Zayatsky Islands; the work was written on the base of those field studies. In the first part of the book, V. provides general information about the labyrinths in Europe, focusing on those of northwestern Europe; he dwells on the topography and geography of the northwestern labyrinths, their form and appearance, and the local names of the labyrinths. The second part is a scrupulous description of the labyrinths of Solovki. In the third part, the author made an attempt to systematize the labyrinths in their shape, orientation to the cardinal points, and so on. He gave different versions of the appearance (ecclesiastic labyrinths, labyrinths of the Bronze Age, ‘pagan structures’, constructions of Peter I). Having examined the connection of labyrinths with other megalithic structures, he came to the conclusion that the labyrinths of Solovki were closest to megalithic structures, and, most likely, they should be associated with the cult of ancestors.
