How fast could a scribe write a Voynich like text?

[dexdex]

My feeling is that the 'committing to paper' part is perhaps not the largest part of the entire creation process.



Also, if the MS is a fair copy, one has to include the time both of creating the draft and creating the copy.

If it contains meaning, that's quite probable, though it could be an encipherment of a plaintext book that no longer exists. Then the author and scribes are technically different, and their motives can be separate and so the time investment may be 'worth it' from each standpoint when it might not be worth writing a book only to encipher it...

Without a decipherment, speculating on the production of the draft is even more uncertain. Scribing we at least can do some guesses. 

Probably having such long text with meaning is a year's worth of labor, I would guess. But poor quality babble with linguistic meaning but full of bullcrap could be done faster or it could be a decade's worth of work by some herbalist, no way to tell.
