Rosettes as a ... magic altar

[Rafal]

But the six central "onion-roof towers" nonono "cosmic drug jars" in the central Rosette could perhaps be the Scribe's attempt to draw a circle of censers...

I haven't thought about it but it is a nice idea which could be followed.

The Rosettes have a lot of these "bubbles". I guess most people would agree that they are clouds. I attach a picture from nearby page with rain falling from the clouds:
   

These clouds could surround heavenly Jerusalem but could be also the smoke from the censers.
And if you think that they are not censers but apothecary jars then clouds are hard to explain.

Notice also how central rosette is connected to other rosettes. There is some flow from it to the other rosettes, not the other way around. I marked it with an arrow.

Maybe it's the smoke from the censers going to other rosettes and maybe it's some magic energy???
