The book “Recueil de plusieurs machines, de nouvelle invention” published in 1720 and written by Claude Perrault is a brief compilation of several newly invented machines which are intended to contribute to the scientific community of the time. All machines explained in the book were invented by Perrault himself and try to either optimize or solve common problems of that era. It has a dedicatory (The Royal Academy of Sciences), a preface, an index and is not divided into chapters but into the 8 machines and a bridge. Apart from two illustrations, one in the beginning and one in the explanation of the first machine, all illustrations are at the end and are referenced during the book with roman numerals. The illustrations are all explanatory drawings of the different machines that fill the whole page (except for one bridge which is the biggest drawing at the end and needs to be unfolded) and have no text apart from the name of the machine and different letters that indicate the parts that are named in the text. The dimensions of the book are 250x200x15mm which would categorize it as a Quarto. It consists of 8 not counted pages and 22 counted ones with a total of 13 illustrations.
