For the fact that the book I should have met wasn’t available at the time, I got a comparable book (Li cinque libri. di architettura by Giovanni Battista Montano Milanese) I could explore.
The book cover of this work is made of bleached red canvas and is fortified with leather at the spine. The paper is of high quality and the illustrations are copperplate prints. This particular collection is divided into two volumes, from which I scanned three books: the second, third and fifth. Each of this segments begins with a cover picture and text that states the number of the following book and its subject: antique temples, temples and tombs as well as different tabernacles.
The book consists mostly of illustrations, to which short descriptions are added. This illustrations are largely pictured on the basis of a section in perspective and a ground-plan, from time to time supplemented by details i.e. decorations or entablatures. Apart from that, there is only text in the book titles and a dedication at the beginning of the volume.
The height of the book is 423 mm, the breadth 277 mm and the width 40 mm. Therefore, I’d relate to the traditional book size “Folio”.
It has (or it should have) 124 pages in total and 122 illustrations, of which one page is missing.
