If it feels like an Alberti Cipher it is one!

[-JKP-]

Ok I'm 100% sure the VMS is written in Latin and I have tweaked the Alberti cipher so that you can put in your own cipher text words which produce Latin words.  I need more time before I post the cipher, because the picture of the wheel is time consuming.

I was wrong about (Daiin):  Daiin is defined as Autem: meaning, "however or on the constrary".

You were just as certain it was gematria, but I'll wait to see the posted cipher before posting any critique of this new idea.
