my suggestion about the author of MV

[rasiratros]

I also do not think this is a palimpsest. but it is obvious that there is another text on some pages, for example, on the first. Most likely the parchment was with a couple of filled pages. The text from which was mechanically and chemically removed.

maby he didn't buy. maby he took from monks a parchment which was meant as a hymnal

When you buy a pack of parchment with a couple of filled pages, you won't use a filled page for the very first page of your manuscript  

This has been discussed many times before, there are several rows of Latin and Voynichese characters in the right margin of You are not allowed to view links.

You are correct that there appear to be some extraneous writings here and there, most of them are well-discussed marginalia such as those in You are not allowed to view links.

I don't think the first page was completely filled. I think this is the beginning of the table of contents of the hymnal, which was never written. Author VM took the parchment (not the fact that he bought it), he needed to scrape off only the right side of the announcement. If you look at the Psalter by link (for example), you can see exactly the same table of contents and also find a few glifs that were used in the VM. This may be directly related to the place of writing the VM, its origin and explain many of the drawings in the VM. You are not allowed to view links. Register or Login to view.
