116v: the "plummeting stone"

[VViews]

Hi all,
recently Anton made a remark about the length of the 116v thread, and this inspired me to create a spin-off thread here about a specific element of that folio:


Reading up the thread, I note that Searcher suggested that it may be related to similar shapes in the You are not allowed to view links. Register or Login to view. marginalia:
"And, finally, the last letter "o" with the four points above it may be not a letter at all. It could be some kind of a pictogram which means a stone (maybe, tartar) which left a body."

Later in the thread it was mentioned by Anton that davidjackson had suggested this could be a kidney stone a few years ago, however I was not able to find that reference ( davidjackson.info/voynich/ appears to be abandoned and all links to articles bring up a "page not found" message... has it moved?).

I am sure there must have been more suggestions about this element, but I can't track them down... So  I am hoping other forum members with better memory than me will be able to remember where this feature was discussed in the past.


Can we try and put together the various ideas about the "plummeting stone" that have been made over the years?
Does this motif appear elsewhere in medieval manuscripts, especially at the end of a text or near charms/spells/prayers/recipes?
