The Book „De Architectura Chivilis“ by Justus Danckerts has a rather conventional text layout. The text lays in the middle of the page with an approximate offset of 1.5 centimeters from both margins (left and right). The offset to the bottom and the top of the pages varies depending on how much text there is and wether there is a headline or not. The headline is at least five times the size of the normal text in the following paragraphs, while the first letter of the paragraph is equally big as the other letters of the headline and capitalized. The font itself has serifs and is easy to read.
The text is accompanied by numbered architectural drawings that were likely printed with engraved copperplates onto the book. Sometimes these drawings are not quite aligned with the edges of the page, while the printing itself always appears to be well done and clean. The drawings and sections of different sizes and rotation are proposed in a frontal perspective or in the cavalier perspective. Overall, they were kept simple and only one comes in form of a fold out spread.
Compared to the text, the images occupy much more space because the book is composed of a numbered index with few comments followed by 40 illustrations. So I suppose that it is a handbook for specific architectonical constructions/problems that offers illustrations of how one may builds or solves them. Also because it is very thin.
