The first book I found is “La militare architettura” by Pietro Ruggiero. The book also deals with military architecture, like “Architectura militaris”. It has illustrations of the technical and geometrical aspects of this architecture. Moreover, the book is also divided into four chapters and shows the pictures only at the end.
The two books are from the same year, approximately the 17th century. Maybe that’s why they are so similar in their content about this architecture because they are from the same time.
As a final note, the book is written in Italian. In addition, the author gives his personal experience, having been a member of the military himself.
The second book I chose is called “nouvelle manière de fortifier les places”. Like my book, it is about how to build fortifications. It is written in French and also dates from the 17th century. It also has many illustrations that can be found at the end and in between. The book is not as thick as “architectura militaris” and does not have as many pages. Like a manual, the book can be read. The author M. Blondel was himself an architect and so he could reflect his knowledge about military architecture in his book, unlike in my book.
