Going through Radi’s book we can see that apart from page 10 none of them are filled with text. My guess is that on page 10 he added a short preface explains the doorway designed he exhibited throughout the book. What follows are a series chalcographic drawings of door designs. However he leaves one page empty after every drawing. The pages I chose sparked my interest as the exhibit his taste and interest for manneristic designers as seen in the works of Michelangelo and the elaborate decorations throughout. An example of that is the drawing on page 116, with the direction of the pediment. Page 55 exhibits different types of decorative elements around the door.
