Let me spell out the situation one last time.
The Barschius letter is a genuine letter from the 17th century, from a man known to be a close frend of Marci, and who left his library to Marci in his testament. All this is historical fact, from documents that Voynich had nothing to do with.
The letter describes a book written in unknown characters, with a great many pictures of herbs, stars and things looking like chemical symbolism. The herbs are described as unrecognisable. Let's call this book 'A'.
It really existed and Barschius owned it.
Now Voynich ended up in 1912 with an old manuscript, written in illegible characters, with mostly pictures of herbs but also stars and other things (yes, nymphs). Let's call this book 'B'.
The argument is now, that book 'B' is a modern fake created by Voynich.
Can it be a coincidence, that Voynich created a book written in illegible characters, with mostly pictures of herbs but also stars and other things (yes, nymphs), supposedly from Prague, that so closely matched one that actually existed (our book 'A').
We are not talking about another 'complete works of Cicero' here. This is a very specific and highly unusual book.
So no, also Rich understands that this cannot be a coincidence, and it is therefore proposed that Voynich must have seen the Barschius letter, and created the fake (book 'B') based on it.
Now, the argument is, that Book 'B' must be a fake, because it supposedly does not sufficiently match the description in the Barschius letter.
Think about it.....
The book 'B', created based on the description in the letter, does not really look like the description, and therefore it is the book based on the description in the letter.
I have argued this before, and perhaps I was not explicit enough. This time, I think that I was, and I will leave it at that.
Everybody may form their own opinion about this. I may not hold it against you
