The first page of the book has it’s title and an illustration under which it says “IN MILANO”. After the title page there if a brief text about lord Carlo di Firmian with an illustration of a coat of arms. The text is written in a more “flourish” type. The rest of the book seems to have a same font type.
After that part we get to the introduction which has either one or two columns. In the introduction and throughout the book we can see one big heading at the beginning and on every page within the topic there is a heading on top of the text in the same font size as the text. Every text of a topic starts with the first letter being in a way bigger font size than the rest. Throughout the introduction there are smaller texts on the side or way below on the page. The page number is always typed at the top of the page, either on the left or right side.
Every chapter has a heading with it’s number (example: “Capo Primo”) and it’s topic beneath the number. From here on there are either two columns, one text or both in one page. Most of the text is in the form of one big text per page. The font size does not vary much.
A bit more than half of the book consists of images. On some of them there are geometrical forms and possibly calculations. Then we get to the columns. Some of the drawings are very precise while others are kept simple. Besides the drawing there is little to no text. One image takes up a whole page and all of the them have a black frame. Above it there is a heading most of the time.
Since the book is divided in half with one being in text form and the other one exclusively consisting of images, the use and reading can depend on the reader but in my opinion the text and images suggests a reading and use for academic studies.
