No text, but a visual code

We already went through this.

Yes, I know, Stolfi.
But now I’m not imposing my point of view; I proposed this particular interpretation to Antonio so that he could analyze it and tell me why it couldn’t be a celestial sphere.

I did not see any version of Oresme's diagram with anything like these spirals.

I don’t really like this approach — “it’s somewhat similar to an Orem map,” but the diagram in VMS and the Orem map are similar ONLY IN FORM.
Of course, the situation is similar to my anatomical interpretation of balneology, but there I’m not trying to force a square peg into a round hole. I’m not trying to fit absolutely EVERYTHING into this explanation. I’m saying that in some places I don’t understand, and in some places it’s ambiguous.
You apparently really want to believe that the VMS depicts the Orem map.

Comparing this illustration with the Oresme diagram above we can see that the squiggly border of the starry area is a mangled reproduction of a cloudband that separated the Earth (the "inverted T-O map") and the heavenly bodies from the Biblical "waters above" -- the vast ocean that lies beyond the 
sky, whose drips are the rain, and, when God "opened the gates", came down as the Flood.

Find at least an image of water within this T‑O map on the VMS diagram.

But the most banal explanation is that the fold-out is a map of an imaginary place. Like the maps that I liked to draw when I was a kid...

The most banal and provable one was meant.
