Helical structure of rosettes page

[Koen G]

This is an interesting manuscript indeed, it also defaults to green for water and has several scenes of people being baptized or otherwise submerged. Searcher's image is about Wetti of Reichenau, who had several visions of hell, purgatory and heaven. I assume the buildings on a hill may represent heaven in this case.

(It's an interesting genre, an evolution of biblical visions like Daniel, Ezekiel and especially Revelation. And clearly preparing the way for Dante).
