Rosettes foldout: cardinal directions?

[Searcher]

Just a general question about the rosette side.
If I assume that it was drawn before it was bound. Should I then assume that the reverse is possibly connected to the front?

I think the Rosettes foldout is a part of the cosmological section, as much as f86v3. In occult cosmological context, the two rocks usually represent the Sun and the Moon, so the Moon here is likely the left rock, the Sun - the right one.
