Voynich Authorship

[Mark Knowles]

Anyway, the crux of your theory is how well you can produce statistically credible voynichese using  a multi-crypt medieval Milanese "diplomatic" cipher.

I don't know what you mean by "multi-crypt". I assume you mean "multiple encryption". I am not sure what you are implying by that term.

As an extant "Diplomatic cipher" is unlikely to be able to create voynichese
then it follows you would have to modify the cipher for it to do the job,
this modification would render any copyright issues moot therefore you could post it here with impunity.

I am not suggesting a theory of how Voynichese might work would be subject to archival restrictions. However historical examples of related ciphers probably would unless manually transcribed.

I am very familiar with comments like these. Through hard work and focus over a number of years I have developed quite a lot of knowledge on this subject. Most Voynich researchers have been relatively uninterested in historical cryptography at the time from which the Voynich dates; exceptions being David Scheers, Nick Pelling and Michelle Lewis. From my experiences all other Voynich researchers are fairly ignorant on the subject, which is fine, especially if you don't think the Voynich is written in cipher. Some researchers think the Voynich might be written in cipher, but has no historical basis or context and therefore efforts to locate ciphers from this time is pointless. Anyway, truth be told I have devoted a lot more time than any Voynich researchers to the topic of cryptography from the early 15th century and late 14th century, so much so that I normally find it much more profitable to engage with academics working in this area or related areas on the subject when trying to expand by knowledge of cryptography of this time, though even then in this very narrow specific area overall I think it is accurate to say I know more than anybody, if not I would be extremely happy to get in contact with someone who knows more than I do. I can't publicly share my collection of ciphers, for reasons I explained, so it is difficult to convey to you how far I have explored the subject of early 15th century cryptography; that is not to say that I cannot learn more, but probably not so much from other Voynich researchers, although I was assisted recently in identifying a letter incorrectly marked in an inventory as a Milanese cipher as being in fact written in Greek minuscule, something I have no familiarity with.
