Any ideas about this detail? (Middle right rosette).

But there is a way to interpret this Rosette that may be you and Cary see as fitting in to your approach.

However, I do want to be careful not to run away with the Revelation approach and start trying to link all parts of the Rosettes to Revelation imagery-- because even if it is the case that parts of Revelation are referenced, the intention may not be to include all parts.

I completely agree.  And Revelations has so much bizarre imagery it's like a gold mine for strange visual stuff.  It's hard to know when it's not justified and is just "possible."

I am not convinced about any of it yet -- but those blue circles -- hundred pound balls of ice.  That one is pretty good to my mind.  Especially given how few literal "very large circular blue things in large groupings" a medieval person would have seen or have referenced in literature.  But, of course, it could represent something else entirely.  Have you and Koen found circles used representatively in this way elsewhere?  

On the flip side, maybe there are examples of medieval illustrations of the hail that could be compared.  I'll take some time this weekend to poke around and see what I can find.  But I guess it could be the only example of where anyone decided to illustrate that part -- there's so much crazy to pick from.
