Another direction to find the answer to the question where Mnišovský obtained his information about the VMS is the idea that it has been reported to him by the person who actually introduced the book to the court - the receiver of 600 ducats. In such case, Mnišovský knew about the matter not as an informed member of the court, but as the member of the circle of scholars (remember that he was interested in alchemy and secret writing). So suppose it was Sendivogius or someone else who once sold the book to Rudopf, and later (when Mnišovský returned to Prague after his wanderings abroad and became acquainted with the person in question) that person just told him this curious page of that person's biography).
