Hi, I think your first illustration has many similarities with the first page of my book „Neü-herfürgegebene Kriegsarchitektur“ written by Christoph Heidemann. You see on both illustrations a person with an helmet and a book in their hand where they show a drawing that is in the book. In both cases the drawing in the open book shows a fortification structure. It looks like the author is showing his book to a ruler that wants to use the knowledge for his town.

Hi, the technic to fold up pages to show bigger drawings is the same as in my book „Neü-herfürgegebene Kriegsarchitektur“ written by Christoph Heidemann. I find it very interesting to see how the limited space of the book page was used to fit in such big drawings. It is nice how different architecture can be displayed whether it is fortification for cities in my case or beautiful sections and measured drawing in the case of your book.
