Could there be more documents written in voynichese ?

[Mark Knowles]

To be precise, this cannot be completely excluded, but I am indeed confident that it is correct.

This is based on many years of study. It cannot be explained in the frame of a forum post.

You say that you can't explain this within a forum post. Have you documented or explained this argument elsewhere?

Without even studying the material in the Vatican archives it seems a very bold claim that there can be nothing there linked to the origins of the Voynich manuscript. I certainly accept that it is possible that there is nothing there that can be connected to the origins of the Voynich manuscript, but I am very doubtful that you can say that with any degree of certainty.
