[split] Diplomatic ciphers

[Mark Knowles]

JKP: I am keen not to reinvent the wheel. So using the term "diplomatic cipher" (early 15th century) describes a whole set of properties. Then what I am interested in is a development or modification of that style of cipher which more closely fits what we see in the Voynich. This could be by adding new features to the cipher or modifying existing features of the cipher. or both. Also the term "diplomatic cipher" points to what I see as the point of origin or source of the cipher, which in my research is relevant.
