The Naibbe cipher

[hermesj]

An excellent and thought-provoking approach! I am pleased to see that my own work on the manuscript’s text appears to have contributed, in part, to the inspiration behind it – my sincere thanks for the kind acknowledgement. 
Although I have so far only been able to engage with the paper on a preliminary level, it strikes me as a promising contribution to the field.
At first glance, the chronological placement of the proposed method seems more plausible than that of my own PIII hypothesis. At the same time, however, the encryption mechanism appears significantly more complex.
I would expect that any attempt at decipherment using the complex codebooks will be extremely demanding. I nevertheless hope to explore the idea further during the upcoming days. 

Hi everyone, thank you to everyone for your questions on the Naibbe cipher. A huge thank-you to the community and to Koen for letting me present at this year's Voynich Manuscript Day.

For reference, the preprint contains everything except my replication of Bowern and Gaskell (2022) and Gaskell and Bowern (2022), which I just got working a few days ago.
