The French book, La perspective curieuse, ou magie artificielle des effets merveilleux, was created by Pierre Daret, written by Jean François Nicéron and published by Chez Pierre Billiane. It is dated 1638. Its medium is engraving on paper and it is part of the Smithsonian Libraries Department.
The Text is placed in the middle of the page and written in a simple, medium sized typeface. The book is divided into several short and long chapters. Every paragraph has its own headline, wich gives the book an overall structure and organization. When beginning a new topic, the author is using complex and illustrated headlines to underline the start of a new chapter. They are always written in capital letters. Only for some letters, starting a new paragraph, Nicéron is using an over average size. The number of each page is located at the top left or right, next to the headline or topic. Until the end, the whole book does not contain any illustration to content.
All important and content relevant illustrations are located at the end. The book although contains much more text than illustrations. There is no text next to any illustration and they are not numbered. They show different perspectives on different objects and seem to be examples on content of previous texts. The purpose of the drawings is that it gives the reader a visual picture of the written topics. The scale of every illustration is just a bit smaller than page size and framed.
The mathematical and constructed drawings of different perspectives, as well as very long and rarely illustrated paragraphs, suggest that the book is used for research and academic study.
