The Blue Stone, Alexandrova Mountain and Lake Pleshcheyevo have been surrounded by legends and traditions since at least the Middle Ages. Some of them are quite understandable. Since pagan times, the Slavs had a special perception of the ancient population of Eastern Europe. Legends about “Finnish” sorcerers are still alive in the Russian North. The cult of stones is generally characteristic of the ancient tradition of the population of Eurasia, but perhaps it was among the Finno-Ugric peoples that it fully developed, and it was from them that our Slavic ancestors adopted a particularly reverent attitude towards noticeable and unusual boulders. How and why were sacred stones revered? Where can you see them in Russia today and what beliefs and legends are associated with them? The next book in the series talks about this and much more.
