What bothered me is that his name is rendered differently in the coin and banknote catalogues in Numista. Some casual reader may not notice immediately both refer to the same person.
N#202700
I think we should stick with one preferred version for the page title and refer to both in the text body (perhaps rendering the alternate name in parenthicals).
He appears on pieces from Ukraine, Russia, Belarus, the Rus of Kyiv/Kiev and perhaps others. Perhaps Numista could have different policies for different issuers.
