The book mostly consists of illustrations. They are all printed one-sided, so the left-hand side of the book is always empty and the illustrations are on the right-hand side.
They show mainly individual buildings or monuments but sometimes there is a comparison between the two. They are illustrated as a sectional view combined with a spatial shading and sometimes a perspective drawing as well. Furthermore, the page contains a ground plan if it is a building and in some cases, details of ornaments and/or other parts of the object. In general, a short description is added to the illustrations.
At the beginning of each book, there is a title and a little text describing the following part. Each of these texts is also integrated in an illustration which indicates the beginning of a new book.
The amount of text on the regular pages varies from page to page. It can be a little paragraph, one or two sentences, just key words resp. names or even no text at all. The font in the title pages is bigger and written all in capital letters whereas the descriptive texts that accompany the illustrations have more of a handwritten style and are written in italic.
All images are numbered within a book and the style of numbers alternate between Arabic and Roman numerals, but none of them are listed in any sort of an index.
In comparison to the text, the illustrations take up most of the space on the print plate. The describing texts seem to be squeezed into the template at times and are quite small in contrast to the rather big images.
I think the book should be regarded as a reference work taking into account the big format and the little amount of written content.
