No text, but a visual code

[Aga Tentakulus]

To put it simply.
A collection of different books, possibly also libraries. Compiled for use with your own experience.
Plants of the region and their uses.
The signs of the zodiac, a kind of farmer's calendar.
Astronomy, I don't know. An area where I have zero knowledge.
Pharmaceutical part. Different types of processing. Already known by the Greeks and taught in Europe (Italy) from 1250. But the results in application with little success.
See the history of medicine.
There is also something about nutrition. About 2 pages.
Recipe section. Whether these are really recipes is unclear. They could (as an example) also be descriptions of diseases.
On the last page it seems as if they wanted to continue with the animal ingredients. But it doesn't seem to have got that far.
The text doesn't really have anything to do with the pictures.
The rosette page. I don't see it as a map in that way, rather as a kind of cycle between different diseases in terms of species and occurrence.
As an example: What doesn't exist in the country, you can't catch. But you can in the city. And vice versa. What doesn't hurt the farmer can hurt the city dweller.
