Very interesting, thanks. But, unfortunately, there is not so clear with the definition of the time period. In the case of the definition time of the burial ground, the author refers to his own articles, and radiocarbon analysis shows only delirium.
I'm sure this is an absolutely reliable study, but in some questions we need to be careful.
