There are some really strange drawings in this old book.
The reason we can’t ‘translate’ it is because the author was just writing gibberish around the pictures, to impress the ladies who listened to his fanciful tales about what he had drawn and written in the book. It is very likely none of them could read anyway.

It's just become the rage again...
the notebooks of a doctor/scientist ? who would have had to keep a low profile on his studies in those days - or face the Inquisition? - if in a Catholic ruled country. Otherwise, the above without fear of the powers that be.
Just a research scientist of his day?
