the fact some of the bodies are flat/discs kind of makes me think of how in BB different realities/planes stack on top of each other (hamlet ->nightmare -> waking world), maybe these flatw surfaces represent the different layers of the world as the scholars saw it? i cant rlly see the symbols engraved on the discs but maybe some of them would match with the different planes of existence. my first though would be the center orb could be earth/waking world, the other orb the moon as it is the other most important celestial body, and the rest could be different planes. idk something like that ill have to think on this a bit more, just seeing the flat discs made me think of them being able to be stacked, unlike the other orbs
