Voynichese is a numeric cipher?

This is an interesting thread! You might enjoy looking at keys to diplomatic ciphers. This folio for example is a ciphered letter of Francisco Despats which features some familiar looking glyphs like 4 and the H gallows (e.g., You are not allowed to view links.

Thank you very much! Well, Occitan ciphers are very close to the topic of the cipher, because there is a good chance that the author or one of the early owners was a person who knew Occitan or lived in Occitania (Nick Pelling translated the notes on You are not allowed to view links.

I'm not claiming, but it seems that the Voynich cipher, being based on a nomenclature, doesn't require any key. However, no one knows for sure...
In any case, it is worth comparing the Voynich manuscript with the examples you have provided. There is still a possibility that the author of the manuscript borrowed from other cryptologists of his time.
