[…]As it turns out, Nicolas de Lyre (1270-1349) used the word “anchiton” instead of “amianton”[…]

[…]To the note – from the commentaries to the “Historia de praeliis”:
[the fabric, which resists fire and iron, which he (Alexander the Great) overmold the iron gates : antichiton and anchiton. The true spelling of this word is uncertain . Muller believes that asbestos is meant.] […]

In German manuscripts, the “c” would often be written like a ligature and would almost disappear into the following letter (very close and tight)—unlike the “ch” above.

In Spanish manuscripts, the “c” is given more space but isn’t usually quite so straight across the top (which is a particular style that I sometimes sample separately from the more rounded “c” if the scribe used both).

Benching is something that tends to show up in Greek (this is part of the reason I always mention Greek in addition to Latin when I am talking about the possible origins of the Voynichese glyphs) and, for the record, some of the very rare loop-m characters that I located that almost don’t have a tail were in a Latin manuscript that included a chart of Greek letters and number systems.

I will post examples of “ch” with a long cee if I find I have enough to reveal interesting patterns.

Anyway, I think you present a good case for “an”. I don’t feel so confident about “chi” though. The H is almost benched. Do you happen to have collected examples of the way “ch” is written in words?
