Could there be more documents written in voynichese ?

[Pepper]

Even if there were other documents written in Voynichese, and if any survived, and if they were discovered, and if the discoverer were sufficiently familiar with the VMS or sufficiently curious to bring them to wider attention, and if they were then digitised and made available to Voynich scholars (a lot of ifs) the likelihood is they wouldn't bring us any closer to solving the VMS. We already have a huge corpus - much larger than most ciphers or untranslated writing systems - along with labels and pictures. More of the same is unlikely to help.

Probably the only things that would really help would be a Rosetta stone, containing a translation of Voynichese to a language we know, or some kind of crib telling us how to translate/decode Voynichese.
