The book Architecture by Wendel Dietterlin is mainly composed of drawings, showing the different orders and how they can be applied in a variety of architectural settings.
Some text can be found at the beginning as an introduction to the book, as well as at the start of each of the five chapters.
The introduction, starting with a letter to Diettlerins “Herren” (engl. Master), is headed by a large title and subtitle. It starts with a calligraphy of the first letter, as can be found in many older books. Interestingly, the first line of the text is written in a slightly larger font compared to the rest of the body. After said exception, the text is then structured in quite regular paragraphs, of which five can be found.
The body is printed in a single column, more or less centered on the first page, but clearly misplaced on the second. While one can figure that it was supposed to be laid out as its predecessor, it is tilted to the right.
The second part is directed towards the reader of the book, who Dietterlin mainly determines as students of architecture. Said text spreads over a little less than a page and is divided into three paragraphs. Just as the letter to his master, it is headed by a large title and starts with a calligraphy and a larger font used for the first line.
Following those passages, and index can be found (also headed by a – rather complicated – title), which is divided into two parts: geometrical shapes and elements or ornamentation. That index relates to drawings found on the next page, and explains the letters used to name the displayed objects.
The rest of the text found in Architectura is distributed as beginnings of each of the five chapters. Keeping in line with the same formation as the introduction, details of the five depicted orders are described in more or less detail, varying from chapter to chapter.
