There are three possibilities. Either :
- both illustrations have the same origin or template, that we haven't found yet, either symbolic or graphic
or
- one is derived from the other. The illustration is more recent than the rest of the book, dated ca. 1410 in the BNF description, just barely inside the 2 sigma range for the VMs C14 dating
or
- the two are unrelated, just a coincidence.
I don't know which option is more likely. I would like to believe that there is some meaning there, a subtle nod to Oresme's work maybe...
