If you made the VMs, ...

Nevertheless, it's an interesting combination of structural similarity and visual diversity.

Yes, but as far as a I know yellow stars over blue background (to represent cosmos) are not uncommon (see You are not allowed to view links. Register or Login to view.), the t-o map orientation on the other hand...

I wonder, if the VMs is a draft or copy, what would the words in the t-o map represent? are these just labels or placeholders for a detalied drawing like in the book by Oresme? If that's the case, thats a lot of text for just "water"

It could say "Some believe there exist antipodes but the equator is thought impassable due to the heat." The Oresme inverted TO map is not the Isadore de Seville version of Africa Europe and Asia turned upside down, it is a more advanced version, where the top right hand quarter is the inhabited side (basically this is the old ecumene, the one in the TO map), the other top side is unknown, incognito (ie america in waiting) and the bottom half is water. There had for millennia persisted discussion of whether there could be land, and heaven forbid, people, on the other side of the equator.
Oresme thought that if there were antipodes , that they would occur only along the equator.
