Is the VM an autograph or copy?

[Koen G]

I think it's hard to determine because copies were rarely exact. So a MS can be a version of another MS without "photocopying" it completely.

A problem with the arguments against copying is of course that so many MSS have been destroyed, due to re-use if the materials, neglect or disaster. With a MS like the VM, I guess that the chance of deliberate destruction is also a bit greater than in general, be it for its occult text or liberal nudity.

Taking everything we know about the imagery into consideration, I would personally think that it is a unique work adapting numerous sources. 

About the text, we simply don't know. The difficulty here is that all arguments against or in favor can be easily countered. Any copying effect might be the result of planning on a scrap medium. Other works in this script might be lost.
