I came across this post as I was searching for ‘fortification’, as well as the term ‘defense’. The book is called: ‘Neü-herfürgegebene Kriegsarchitektur’.
Its main focus is very similar to mine, which is about warfare architecture: defense, attack and fortification. In the Xenotheka search the publisher of this post seems to have come upon the same book as an other Student from my Group, who reverenced to ‘Frederick the Great, on the Art of War’ as well.
I looked at other posts about Book_39 and its physical as well as its editorial characteristics are very similar as well; lots of pictures, almost artworks as I could find in my own book.
As i searched the blog with the term ‘fortification’ I also came across a post about the book ‘Architectura militaris’. Before I even noticed the title, the publishing year caught my eye: 1645. About the same time as my own book was published. And then with the title I choose this post as my second comment.
The topic overlaps with that of my own book. With the difference, that this book concentrates on Europe especially. And it also seems to be a bit more mathematical than mine. But still the topic of warfare stays the same. It also is split up into large chapters with each one main focus.
