some pages) that suggests that the VMs is an encoded copy of an existing
document: plus there's evidence (in the alphabet itself) that at least part
of its cipher system involves a verbose cipher (qo, dy, ol, or, etc). So,
if the effective average length of letter-representations is longer, but
the lines are probably the same length, there's good reason to suspect
abbreviation (truncation or contraction).
Mark Perakh's analysis of the differences between the A and B languages
also suggests that abbreviation is likely to be an important factor in the
VMs (though for quite different reasons).
However, we also have a fairly good (though I'll admit it could be
improved) idea of what abbreviated Italian text looked like circa 1450, so
we're far from "lost".
Also: if anyone can definitively prove that numbers of any sort (whether
codebook indices or otherwise, whether Teague numbers, Tiltman Roman
numerals, etc) are involved, then I'd say we're definitely "found". But AFA
I'm concerned, that's not ~quite~ true just yet. :-o
