Tell tale signs Marci letter forged by Wilfrid V.

[ReneZ]

The most interesting argument (I find) that the Marci letter isn't a modern forgery is that it is logically impossible.
This is a bit of a thought experiment, and requires one to forget certain things that are 'known'.

We know that the Voynich MS was sent by Marci to Kircher in 1665.
How do we know?  We know from the Marci letter.

Now go back to the time that Voynich supposedly started his forgery of the MS.
So we need to take away the Voynich MS. It doesn't exist. It was the product of W.Voynich's imagination.
Now also take away the Marci letter. It's not there, but again, it is a product of Voynich's imagination.

So, where do the roles of Marci and Kircher in the history of the MS come from? What is the source for all information contained in the Marci letter?

Some of that is *only* contained in the Kircher correspondence:
- the fact that the previous owner of a mysterious book wrote to Kircher
- the fact that Marci had sent a mysterious book to Kircher.

Note also, that several other things cannot be found in the Kircher correspondence:
- Marci's inheritance of Barschius' books
- The name and identity of Dr. Raphael

The most important thing is: to find out about the roles of Marci and Kircher, and the fact that they had anything to do with the transmission of an undecipherable manuscript, one would have to search in the correspondence of Marci and Kircher.

It's a vicious circle.

In short, in order to forge the Marci letter, one would have needed this letter in the first place in order to know what to write in it.

Let me add a picture of the manuscript collection in the archives of the Gregorian University. As a very rough guess, it is at most a quarter of the collection that was still hidden when they sold their old manuscripts to the Vatican. The Kircher correspondence (14 volumes) is somewhere among these. I don't think they are visible in this picture. I also think that all of these manuscripts were still packed in cases in 1912.
Just 'bumping into' the various letters that are in three different volumes among these >2000 is certainly not realistic.
