Six onion-roof towers supporting heavens

[JoJo_Jost]

Indeed, the breadth of topics and this apparent absence of shared contents tells me that the contents does not come from the Author's own experience  or elucubrations.  Rather, each section seems to have been copied or abstracted from a separate book.   Except that the plant sketches in Pharma may be based on the Author's first-hand observations.

That's nothing more than a theory, your theory.

The fact that certain things on different pages can be found on others. The vessels in the middle of the large map, the roots of the plants on the pages with the vessels,  vessels from these pages in the Balneological Section, even circles from the pages before the Balneological Section can be found in the  Balneological Section, the distortions in astrology. Nymphs in astrology. All of this indicates that something belongs together here.

Sorry, but it's just striking, everything seems to be interwoven, and why not, it's one ‘manuscript’ in one (or two) ciphers.
