You have said this before, about 5 years ago. I believe there is a tradition for this design in cartography, and in fact that is how i see it, standing for, as you say, slabs, in my case, of rock. May I ask how you equate slabs to astronomical items? What are they slabs of? I don't think I have seen this particular usage elsewhere, it may well exist, but i don't think anyone discussing it at the time could support the argument.
JKP said in this thread around that time:
Quote:Ideas are important. Ideas can sometimes lead to solutions. But proving an idea is still paramount. Without proof, it's simply an idea, one that might have been considered by many people but which is an empty vessel until you fill it with evidence.
Please provide evidence. Your vessel requires a refill of substance, not a simple restatement of something that didn't seem to go anywhere the first time.
There is a six towered round building in a quarter of the circle. Do we know yet what this is all about? I think I asked then, but I don't recall if anyone knew. Can you explain what you think is going on here? What is this meant to symbolize and what does it stand for in relation to that quarter and with the scale numbers? I tend to doubt it has anything to do with any of the architecture in the rosettes, but i would need to understand the page better to be able to speak directly to that. The drawing style is certainly different.
I found another one with similar architecture, this time it is easier to understand.
I assume you are attempting to equate the 6 towered one with the rosettes central towers, i can understand that. But I do not see any interaction between the architecture and the embellishments that would somehow equate them to the superficially similar icons in the rosettes, other than whatever resemblance there is visually with semicircle topped slabs with dots or smaller circles inside.
I went to find an image I could post, (I since added the one above too) in case someone did not look at the example you gave, as it loads very slowly for me. This one is from a page discussing the darkening of the sky at the crucifixion, so don't worry about the attached images, it came that way. I am posting to show the decorative corners with your description of dotted slabs, albeit this one is even more decorative than your presented example.
And this is what you are equating these embellishments with (except it was page 108 I think)
Are you saying that Enrique de Villena meant these decorative corners to represent the sphere of fixed stars? Has this been mentioned by anyone else before you? Evidence, please.
I still think it is fanciful embellishment, as it is also used in the decorative initial letter as well. Filling in the void, not with stars, but with intricate doodles. In this one he adds another icon, kind of a floral x. What would these be in an astrological sense? Perhaps a heavenly boundary. Or, again, decoration.
Here is some evidence that it is common to fill the corners of circular astrological drawings with random designs.

I agree Enrique's treatise on Astrology is scientific looking and beautiful, although i couldn't get more than a few glipses due to the pages taking forever to load on my device. However I did read that he had a reputation as a necromancer and that another of his works was A Treatise on the Evil Eye. I wonder if this colours his decorations in another light. Some of them seem to have diamonds and spades, diamonds could be argued as stars but with the spades it seems more like designs on the backs of cards. Also although I see the shapes and the dots, (which are a bit different too), they are also laid out quite differently from those in the vms, it appears to be from a different universe if we are comparing them against each other as such, even if we take them for what you say they are.
