In my label work I have found there are three sets of values for the labels, but none work on the regular text.
Below are the values for what I have designated as Set 1. These were the first I had luck with on f68r3, and as can be seen, are not complete. Set 2 is completed, but Set 3 still has 5 values missing.
Note that “4o” can have a value of “AL”, the beginning of many star names, and that EVA iiin is “IUM”, a common Latin ending.
As has been determined by others, it is not a simple substitution. The multiple values for some letters follows Philip Neal’s work. My reasoning is: if the Voynich letters are interchangeable, the plaintext values should be as well. This raises the “degrees of freedom”, but I will address that later.
I have, at this writing, nearly 100 labels cracked. So far, star labels are star names, many archaic (as might be expected). On f67r2 the twelve words under the moons are country names, eight of which no longer exist.
