There is one column of text per page, the font type is old and calligraphic and the size of the headings varies between 11 and 20 points, but most of them are 12 points and they are written in capital letters (except for the brief descriptions following the title of each chapter). Those descriptions are cursive and the same size as the text, which is 11 points. The text is left-aligned with a margin of about 1/8 of the width of one page towards the middle and the top, and about 2/8 towards the edge and the bottom.
Throughout the text, there are a couple of Latin sections, that are either cursive and part of the text or in a separate segment, written in capital letters and slightly moved to the right.
There is a description of Teofilo Gallaccini’s life by Antonio Cone Pecci and a few pages dedicated to the pope (Urbano VIII), which do not contain any images. They are followed by the text about the mistakes of the architects, which consist of a preface and three main parts, which are divided into chapters. The preface and the first part do not contain any images either, whereas the second and third part do. The second part consists of layout plans, sectional drawings and sketches in the first few chapters, of drawings of proportions in historical buildings and mathematical sketches in the other chapters and text. The third part does barely contain any images and those are perspective drawings and the rest is text. There is a brief description to every image in a cursive font. The images are scattered throughout the text and take up the entire width of the text column. They might fill an entire page and be combined with other images.
The organization of text and images and suggests and academic study.
