Maria Shvarnovna, the first wife of the Grand Duke of Vladimir Vsevolod the Big Nest. The burial contained the remains of four people. This amazing discovery led to a whole investigation to find out: who were these people and what relationship did they have with each other? Step by step, the historian still manages to unravel this mystery. Along the way, other questions are also being resolved: who was Mary’s ethnic origin - “Asynya”, that is, who came from the Yas people - the ancestors of modern Ossetians (as the ancient Ipatiev Chronicle believes), or whether she came from the Czechs, as the chroniclers of the XV-XVII claim centuries?
