The book «L’architecture militaire moderne, ou fortification» by Matthias Dögen is organized in different chapters which are about certain aspects of military architecture and the specific military architecture in different cities, mostly located in the Netherlands.
To demonstrate how those military sites (should) look there are many images scattered throughout the book. Some are rather small, some are full pages or even on foldout spreads.
The pictures are drawn very accurately, so that they can be taken as some sort of ideal for future military constructions. They sometimes have clear information about how the constructions. How long, high, in what angles and how thick, everything is written down precisely.
Besides those very accurate drawings there are also some a little bit less precise drawings. Those are most often the illustrations of a city and their military architecture. On those you can see not only the fortification a city has but also some part of the city and its surrounding.
The images play an important role inside the book because they help understand the written knowledge.
The text is mostly written in font size 10, although not all the time. They used italics to highlight certain parts of the text and it even has some side notes which are written even smaller. There is only one column and plenty of space on both sides of the column.
The text is formatted so that it always using the whole rectangle it was attributed (As if it would have multiple columns).
Besides the italics and the side notes there are also letters in brackets. Those letters are explained in the footer.
This book is most certainly a book for academic study of architecture and especially military architecture and fortification. You would not read this book “just for fun“ although the illustrations are nice to look at by themselves.
