Mark Knowles' theories of pharma and other labels

[MarcoP]

You seem to believe that Voynichese cannot be related to diplomatic ciphers of the period as you seem to be saying that the Voynichese cannot have features connected to or related to that of homophones. Is this a correct assessment of your position?

Everything is possible, but some possibilities explain more of the evidence than others. Here is a comparison between a few observable systems:

• The VMS
  
• Fontana's cipher manuscripts (e.g. You are not allowed to view links. Register or Login to view.)
  
• The XV Century diplomatic cipher You are not allowed to view links. Register or Login to view. you mentioned a while ago 
  
• Trithemius' steganography system "padiel aporsy" (see You are not allowed to view links. Register or Login to view., or You are not allowed to view links. Register or Login to view.)
  
• You are not allowed to view links. Register or Login to view. (XVIII Century) 
  
• You are not allowed to view links. Register or Login to view.
  
• You are not allowed to view links. Register or Login to view.
  

   

These are features I find significant, others might make different choices.
Among the historical systems, Fontana and steganography appear to be closer to the VMS (though with considerable differences). 
Both Timm and Schinner's and Rene's systems are good matches for some of the features of the VMS: T&S match more features, but mod2 has the advantage of being a cipher system that can encode any meaningful text.
The homophonic cipher in the Copiale ms and the Diplomatic cipher produce something that is completely different from Voynichese: these systems do not fit with the observations.
