If it feels like an Alberti Cipher it is one!

An Alberti cipher is one of the things we can be sure Voynichese is not. In fact, the two are close to opposites in all useful senses.

Hi Nick,

Are you suggesting this statement, because of the carbon dating?  This cipher does in fact eliminate a frequency analysis which would indicate this mechanism.  Why are they opposites can you explain the vague statement?

Using a cipher disk to encipher a plaintext will inevitably produce ciphertext where (a) the letter frequencies are very much the same as each other ("flat"), and (b) where there are no obvious letter-to-letter structures ("unstructured"). Voynichese, by way of comparison, is not flat at all and is also highly structured (and in many different and unexpected ways).

So... no. I'm making this simple and direct statement (a) because it's true, and (b) because you're wasting everyone's time here by posting these claims here.
