Here it becomes clear how the “inventor” imagines the function: However, it is upside down here.
There appear to be two different devices, those that are permeable and those that are closed on one side.
And here you can see that he basically wants to build a plant's vascular system from root to flower using these tubes.
From the root to the flower.
I think some pages are missing, because on one page you can see a device that only corresponds to leaves. There should also be some that imitate flowers. You can see these flower parts on the pages with the women, usually above their heads. There is only one thing about flowers that I have noticed so far.
These flowers, once “real,” once a functional unit. The more you delve into it, the more evidence you find for the theory, especially since it actually makes sense in the context of the Middle Ages.
I know you think this is complete nonsense. But I would be careful, because it could explain everything.
Let's imagine that the author had the idea of condensing and replicating the healing powers of plants (as crazy as the idea may have been, people have always had crazy ideas).
What would he have to do? First, he would look for plants that were known to be medicinal. Then he would examine their vascular system. That's what he does in the Herba section.
In a second step, he would try to find out when the plants have the most “energy.” In other words, when which plants have the best effect as medicine. There are plants that should be harvested in the spring and others that should be harvested just before winter in order to obtain the highest concentration of active ingredients. This requires an astrological section.
He then describes the plant's vascular system as a generalized concept (this is the part about the nymphs, which I imagine represent the “amount” of healing energy).
Finally, he designs a system of tubes onto which he magically projects the properties of the plant parts (as I said, people at that time believed that this worked).
And then he writes a construction plan, specifying which tubes he wants to connect to which ones and how.
And there you have the entire Vonich manuscript.
