Yes, I think the illustrations are too close not to be derived from the same source, and because of the dating it seems more likely to me that the VMS illustration was based on Oresme’s or some knock-off of his work.
What’s interesting to me, beyond the similarities, is the text BNF Fr 565 is illustrating. Aristotle’s On the Heavens. I think too often we’re presented with similar illustrations as if that’s somehow definitive but the textual context is then under investigated, as if dating is the only thing to be derived. . My own theory regarding the rosettes page and the balneiligical section relies heavily on Aristotelian natural philosophy as one of its foundational pillars. This illustration might not help the dating, but it certainly serves up yet another potential piece of useable evidence for my hypothesis. Moreover, by reading the text - which is what it seems to me was what interested the VMS author(s)- then the the differences between the two illustrations and the choices the VMS authors made in its changes might also be illuminated.
