A bird's eye view of the celestial city, encircled by a cosmic boundary, why not? And the other rosettes are other cities, countries, or planets. It's the sort of situation where one would like to make a decision based of the accumulated weight of evidence. Unfortunately, while there is plenty of data, there's not a lot that can be called unambiguous. That is why the fancy version of the wolkenband in the Central Rosette may be significant. The elaborated pattern on each of the individual bulbs in the nebuly line has very few structural equivalents besides the illustrations of d' Oresme and de Pizan.
