Przybysław Dyjamentowski
Przybysław Dyjamentowski (1694–1774) was a notable Polish documents forger and writer. In his lifetime he prepared several "ancient" chronicles, diplomas and genealogies for sale.
Dyjamentowski's forgeries were not always recognised as such, although they are now regarded as entirely pseudohistorical, and have at times been influential, even in the twenty-first century among a minority of Polish nationalists.
