The title of the book is: “Architectura militaris”, written by Andreas Cellarius in 1645. It was written in German and has the old style of writing. This book is about military construction in early times in Europe. In other words, about the fortifications and how they are built.
The book is structured in four large chapters. Each chapter starts the same. For example, “the second book of fortification” and ends the same (for example “end of the fourth book “). After these four chapters follow the pictures and illustrations of military construction, as well as many calculations and notes from the authors themselves. One finds very many figures/ tables on various subjects. In the end, one finds various tables with dimensions. The pictures are true to reality and are presented very precisely. For example, the installations and weapons. In different perspectives the drawings are shown, especially in 3D they come out very well. The book seems very detailed. The construction of the facilities is shown to the smallest detail. In addition, a lot of information is given about the subject of the book. That is why it is thick and compact.
The author of the book was a German astronomer/ mathematician. He is known for his astronomical discoveries. Probably he wanted to build an ideal city with his book “Architectura militaris”.
Overall, the book is very mathematical and contains everything about defense. It is very interesting what different variations and forms a military location can be built. For this reason, it is one of the basic books for teaching architectural theory.
