Hi Dennis,

        A brief comment here about transposition ciphers.
Transposition ciphers seem very unlikely to me due to
the low second-order character entropy of VMs text and
the highly structured nature of Voynichese words.

Certainly, "Rail Fence" transposition ciphers (as described in most history of cryptography works - and Wikipedia's account is no exception) seem unrelated to what we see in the VMs:-

However, this whole model would seem to rely on a very "serialistic" print-centric mindset (ie one character at a time, along a regular line), which one might date to after 1500. But remember that I recently described Neal keys as possibly being a quite different type of transposition cipher (extracting rare letters from a stream and placing them elsewhere on the page): and there are, again, yet other types of early modern transposition cipher which might be in evidence here.

Cheers, .....Nick Pelling.....
