Jean du Breuil, l’art universel des fortifications , Paris, 1674
I chose the following image because it is the first illustration of the book, it has some kind of introductory role.

I chose the second image below due to its link with the first image, it is essentially the same drawing which Mars is holding in the first illustration.
