The "Naibbe Cipher"
Another take on the world's most mysterious 15th-century codex: The Voynich Manuscript.
Michael A. Greshko in a research paper proposes that the bizarre text may have been created with a cipher. He called it in his experiment the "Naibbe cipher".
Note: "Naibi" meant playing cards in 14th-century Italian. The word was born in Florence and comes from the Arabic nā’ib. "Naibe" was an alternative medieval spelling. Doubling consonants - like bb - was common to indicate a short, closed vowel before it.
Research is shifting from "reading" the text to focusing on how it was made. By identifying the possible tools (like the Naibi-style cipher) we can build a map of the lock. Perhaps soon, AI will help us find the key.
Reasoning draws a conclusion... but does not make the conclusion certain, nor does it remove doubt so that the mind may rest.
