The pages of the book “les fortifications de chevalier Antoine de Ville” have a clear structure. Each page has a text column consisting of about 43 lines.
On the side of the text column there are single words or single phrases written. I think their function is to explain what the respective paragraph next to it is about. This helps the reader to not get lost or confused when reading the book and it makes it clear what the main topics of each page/paragraphs are.
There are many different typefaces used in this book. The index is for example written with an italic type font. The chapters are written with several styles of lettering. The font size also varies a lot throughout the book.
There are several types of illustrations in the book: architectural drawing and also perspective views. When looking at the illustrations, one recognises that some drawing are very similar. I think that the author is developing a drawing further and further and thus some illustrations seem to be representing the same things.
There are some illustrations in this book that don’t really have a purpose other than “decoration”. For example at the end of every chapter there is a small drawing. Very often it’s a flower.
The images are scattered throughout the book. Most of the images are as large as a single page, some even take up two pages. The images are all numbered. But there isn’t an image index. In comparison with the amount of text in this book, there are very few images.
In the end of the book there is an alphabetic index containing all the main topics of this book. It is my conclusion that this book is to be used as a handbook
