The history of Ancient Rus' is full of mysteries. No more than one percent of the richest literature of Ancient Rus' has reached us. Of the many thousands of masterpieces of ancient Russian wooden architecture, only a few and very late examples have survived, created already in the era of well-developed stone construction, which led to the decline and significant degradation of wooden architecture. Only ruins, garbage pits, the remains of foundations, a few texts and old, very old things, most of which have reached us only because they were either thrown out, having become unusable, or accompanied the owners to another world (and what can they find out about us? our distant descendants in our graves?) - that’s all that in most cases we have to be content with when reconstructing the spiritual and intellectual world of bygone civilizations.
