Anton,
I agree that its placement sets it apart from the other illustrations on the page.
Like the crosses in the line above it, it seems really embedded into the text, and seems to mark it or punctuate it rather than illustrate it.
Its location as the final sign on the page and in fact, as the final sign in the entire MS makes it particularly interesting to me: much like the big red weirdos which initiate the text, this is the sign that ends it.
I know this is completely anachronistic (and probably something I should rather post in the Voynich humor section) but it behaves almost like of some sort of a Voynichese version of a mic drop
bi3mW,
Interesting, if it is an illustration, then the "urinary gravel" is definitely a great candidate considering the nearby goat. The thing that makes me doubt this interpretation is that medical manuscripts tend to place illustrations in the margins, not right in the middle of the text zone... or are there such examples?
Koen Gh,
Yes! I too recall seeing something similar in Hebrew manuscripts, but I really can't remember what or where it was... for some reason I am remembering this motif as a decorative feature only... hopefully references to this will surface again.
It is tempting to read this as a downward moving object, but what else could the small dots above the "stone" be?
Going back to Anton's idea of the drawing as a sign, I wonder if it could stand for something like "precipitate"?
