Who is the author of VM?

[BessAgritianin]

Providing an author's name should by no means be expected of proposed solutions. Most medieval scribes were anonymous, and most named authors were older sources or pseudepigraphal.

I tend to be slightly more cautious when a solver has an author in mind, because it usually means the work is driven by confirmation bias.

If the name is written on the firs foil, no matter a real name or a pseudonym, one who believes to understand the text and provides solutions, should had read it. Also the author is not the scribe, or the writer (methinks).
 The author's origin will rise questions and maybe provide more answers explaining some of the foils...
