A random rant about the VMS

[Rafal]

BNF Fr. 565, Harley 334, and the VMs share an uncommon, rather simplified, cosmic structure: a central, inverted T-O Earth surrounded by a field of stars, enclosed in a cosmic boundary. The typical medieval cosmos, in contrast is built upon multiple concentric spheres for the basic elements, for the planetary orbits, and for the various heavens.

You need to remember that the picture in Nicole Oresme isn't scientific but mostly artistic.
It is actually bigger that what you are usually shown as people often cut out "unnecessary" part.

Now I'll give you a rare chance to see it complete 
   

This picture isn't supposed to show and explain the structure of Universe. It shows an astronomer giving his book to a king.
The Universe is simplified and doesn't have any text because its only goal is letting you know that the book in the picture is about astronomy.
The details are explained elsewhere.

The picture in VM on the other hand doesn't have any kings and seems to be more information loaded. But as we cannot read the text, we cannot be sure.
