"Ancient Rus' and the Great Steppe" is a significant work. But to better understand it, I recommend reading "Ethnogensis and the Biosphere of the Earth" or "The End and the Beginning" first. They reveal the foundations of Lev Nikolaevich's concept.
Thank you:)
The thing is, I have "Ancient Rus'," but I don't have "Ethnogensis and the Biosphere of the Earth" or "The End and the Beginning":(.
