The structure of this book is on every page the same, on the left side is some text, mostly about the five orders and on the right side are some illustrations. The pictures are always framed and informations are given by some words or measures. The illustrations never show a complete building, just details, as an example: a column or a sculpture. There are organic ornaments on specific pages, they might underline the content of the sections of the book. The illustrations are very detailed, shadow is also drawn which is resulting in a three dimensional expression.
