Creature(?) in Rosettes page

[Linda]

I think this is the challenge of this manuscript in both the words and pictures. It has a strange mirror property where anything anyone wants to apply to it can be true...

I agree with that assessment. The variety of coexisting possibilities presented is amazing. Many times I can see them too, if I let go of my own view for a while.

For me, it's obvious that the central rosette is a view of San Marco (and I know I'm not the first to say this), the top right is clearly a walled city like Padua or Citadella, or Monselice or Este, and the middle top and bottom looks very much like abstractions from the inside domes of San Marco .. 

But that's only because I'm convinced it's a Venetian/Paduan production.. If I were convinced of it being Chinese, I'd pick other things .

I am curious, what in particular is the bit that is shown to be a creature here, in your Venetian/Paduan view? Are there other parts of the manuscript that convince you of these aspects, or just the Rosettes?
