The content of the book represents “the five orders” from celebrated architects. The five orders contain descriptions of columns, doors and windows. In addition to a very precise illustration there is always a text or most of the time a table with the proportions of all the details. Every second double page is blank and they are not numbered unlike the others. The exact dimensions of the book are a height of 17.2 cm, a breadth of 11.1 cm and a width of 1.8cm. This format can’t be clearly assigned to any of the traditional standard book sizes, it is something between a “octodecimo” and a “sextodecimo”.
The book has 102 pages which contain 24 illustrations. The pages are not devided in chapters but there is a preface at the beginning.
