It's not that Gemini created this solely from the image; that doesn't work. I had to give it very specific instructions, and it's very difficult to get Gemini to change small things. So please understand this as an approximation, not perfection. In addition, I only focused on the circle in the middle of the nine circlesand, as already mentioned, created it in the context of a possible cross-section of a plant.
But here's something else:
Here is a schematic representation of the structure of a flax fibre:
You can see the different circles. The bast fibre bundles are also not round. There are different shapes in the outer areas of a stem, where water is usually transported: round, angular, oval. Especially when you ‘stamp’ to see them, the proportions change again.
Then there is this picture of flax fibres. Here you can see such ‘tube bundles’. And also differently shaped circles.

"In herbaceous plant parts, they are often grouped together in vascular bundles, the strands of which can be seen with the naked eye when a stem is cut open."

The impression of a curve in the circle is created by the fact that the tubes cannot be shown from above, as they would then only be circles.
There are so many different plants. And very few plant cross-sections on the internet. Finding the exact plant that is possibly depicted here is almost impossible. But you can make out the different areas, as they repeat themselves. And strangely enough, these circles and structures fit in almost perfectly, as i have shown.

I find it much more plausible that a book that is almost entirely about plants would not suddenly describe something that has nothing to do with plants.
It is understandable that a section on
astrology would appear in such a book. Astrology itself is important for plants. The course of the sun, moon and stars has always been observed to determine planting and harvesting times. And the (healing) powers of plants have been associated with astrology.
The
nymphs with their tubes fit perfectly into the idea of harnessing the power of plants. The consistent similarities between the vessels in all these images show that something belongs together here.
But why should a
world map, castles or even cannons appear in such a book???? That is actually much more far-fetched.
This does not mean that the theory presented here is better, but in my opinion it is definitely closer to the context.
