This is a remarkable work by Vitruvius Pollio that was created during the classical period and that influenced greatly the further development of the architecture. A number of outstanding sciences of Renaissance referred in their works to this book. The book includes not only data on architecture but also a great number of digressions from this topic. For example, here it is possible to find the paragraphs about different kinds of contemporary art which are also as valuable as the information about architecture ingenuously. When talking about the architecture itself, the author pays great attention to the construction of siege and defend devices, for instance, catapults and tortoises. The book also contains information about divining water and using building materials.
