Direction of labels on rosettes foldout

[Anton]

I think it's all pretty simple, and he inscribed the labels as he "followed" this "map" or "chart". Which is the starting point I would not tell at a glance, but surely the default orientation is as it's been scanned by Yale - with the domes of the heavenly Jerusalem facing upwards. Then suppose he started from the section left to Jerusalem and went upwards along the "path" toward the circle with the orarol pipes. And so on, clockwise. In fact, the "paths" may have been drawn in the same pass, after the circles were already in place. E.g. the supposed lighthouse of Alexandria looks rightwards, not leftwards.

There are some labels though that are not in line with this direction.
