The book is divided into five parts. The first part is divided into eight sections, while the other four parts do not contain sections. The text on the pages of the sections is organized into problems, plates, and numbers in the first part. Each problem block contains a subtitle that gives more information about what the problem is about, a text that explains the solution, and a character that is on one of the disks that illustrates the problem. A plate contains many different figures from sometimes more than one section. The text is organized in a column. Each block of text starts with a large letter and the first word is always capitalized.
In the first part, many different geometric illustrations (also known as the figures) are arranged on a plate. The other four parts contain architectural drawings, facades, illustrations about proportions or details.
The images are always on a different page than the text. The plates are scattered throughout the book, because the images refer to the text, and the images always come after the explanatory text.
Each page with images represents a plate. A panel can contain different figures, architectural drawings, facades, or details. The plates are numbered sequentially in the book, regardless of the parts or sections.
The pictures take nearly as much space as the text. The are important for a better understanding of the text and illustrate the meanings of the text.
If you read this book you start with the text. Because the text refers to the plates and the figures you will automatically search those for a better understanding. The book is kind of a handbook. It contains of many different information’s about geometrical problems and their solutions, the five order of architecture, the proportions of the human body, staircases, practical uses, etc.
