The Book is all about the perspective drawing. It explains the topic in a very uniform and repetitive schematic. The main part is always a written description on the left and a visualisation on the right page. It is quite remarkable that you can understand the concepts only looking at the drawings. At the end of the Book is a collection of different perspectives. They show all kinds of objectes, from ancient temples to abstract composition. In my opinion they can be understood as a summary and an overview of the possibilities of these technics.
