Sorry I should have posted on the 'nomenclateur' that Speziali
shows in his article. This is a list of trigrams found in the coded 
message with their meanings. I  have scanned it as a jpg and 
attach it to this message.

It appear that this was a list or dictionary necessary for the
decipherment of the message. Perhaps codes like these were
developed in which special identified words in the text were 
treated differently. Some words decoded using some sort of
substitution common in the period but others needed to be looked
up in a dictionary. Here it was trigrams. Perhaps it is some similar 
kind of mixed-method code that lies behind the Voynich, and that 
is why it seems impervious to the decoding methods tried so far. 
Without access  to the dictionary it will probably be almost 
impossible to decode it.  However, it may be that codes like the 
one found by Speziali are quite common and that their dictionary 
structures had sufficient similarities for someone to try to 
reconstruct the Voynich look-up table. It would need someone
to try and find examples of such dimplomatic codes of the early 
16th century. Surely someone, somewhere has done a Ph.D. on 
this.
