If it feels like an Alberti Cipher it is one!

[coded]

David,

Friedman and Tiltman looked at this one *very* intensively, in the case of W.  Friedman at least four decades.

In any case, it is obvious that the Voynich MS is not the product of an Alberti wheel cipher.
This simply does not generate the word patterns from a text that doesn't have them in the first place.

Worse, like other poly-alphabetic ciphers, it causes the same plain text word type to be translated into different cipher text words, depending on where they occur in the text. It flattens out the Zipf curve.

Its rare when a vord will share two different Latin words and the nightmare about this cipher is not just the rotation but the glyph interwoven keys so that it looks as though the text is meaningless when its not.
