Which other manuscript contain the most Voynichese glyphs?

[-JKP-]

...

While I have your ear: you say there are 3 variations of EVA-m type characters resembling -cis, -tis, and -ris.
Are these covered by Extended EVA characters 166 and 174 or are they something else again?

Don, the truth is, I don't even use EVA, I developed my own fonts. I have glanced through enough versions of "EVA" to understand that there are MANY different opinions about how to interpret the glyphs, and no real consensus on some of the variations. I noticed some versions of EVA recognize ris and cis but left out tis (ris and tis often look very similar in medieval manuscripts, as do cis and tis in early medieval manuscripts, so perhaps not everyone notices that there are three variations).

There are actually more than 3 variations in the VMS. There is also a character that looks like EVA-d with a straight back. It resembles the short-cis sometimes found in Latin-alphabet documents. It has to be figured out whether this allies more closely to EVA-d or to EVA-m. I probably have some statistics on this, but I have run so many statistical tests I can't hold them all in my head any more. When a question comes up, I have to look them up.

What do you think of these as possible precursors to EVA T?

I just cannot come to terms with our elegant tall gallows arising from a little squashed fly like tis etc!
I'd rather go with Pi actually.

When the abbreviation symbol for "-is" is added to capital-I (rhymes with eye) to create "Item" (in German, French, Latin, or Italian), it looks exactly like EVA-k. In certain hands, the French word "Il" also looks like EVA-k. It's really not much of a stretch to base EVA-t on EVA-k as a variant if one is designing an alphabet (or scribal system) for one's own purposes.

But, to be honest, I am also inclined to keep Pi high on the list because there is a great deal of overlap between Greek and Latin scribal abbreviations and quite a few philosophy, theology, language, and science scholars learned Greek in the Middle Ages.
