The text of the introduction of the book fills the whole page. After this part it starts with the six main parts, which each one of them is dedicated to a form of fortification. These six parts are divided again in under chapter, which leads to the occasion of nesting of under chapters.
From now on all the texts in the book appear in the dual column system. Above the text is a horizontal line, and above this line is the title of the current chapter, which helps the reader to keep the overview.
We can perceive that they tried their best to save pages (seen physically, as I suppose the paper was not that cheap). We recognize this in the way the text lines are compressed, and they didn’t even take a new page for a bigger new chapter, which makes the organization a bit less clearly laid out.
Decorative elements at the end of chapters appear but not very often.
To support the descriptive texts in the first half of the book, the second part of the book consists only of drawings. The mayor part of the drawing are floor plans, but there are as well some cross-sectional plans. I suppose the book is rather a technical and strategic adviser because of the many architectural drawings and the clear lack of perspective view and detail plans.
These drawn plans are always full-paged and organized as a foldout spread. We can recognize that these drawings were made separately and then glued into the book. Because every drawing belongs to a specific text, they need to be numbered. Every image is labeled with a Greek and a roman number, this signals a strong systematic organization of connecting the text with the belonging images.
Text and image seem to be both equal important and only working in relationship with each other.
After analyzing the system, I would say they used this book as academic study, because the book goes very in the details what single fortifications concerns. Therefore, it may work as well as a reference book.
