La militare architettura overo moderna fortificatione del capitan pietro ruggiero dedicata all`altezza Serenissima di d’gio d’ austria. The book is a piece of technical literature on modern military fortresses, the modern in question being the 17thcentury when the book was written. The book is written in Italian by a certain Capitan Pietro Ruggiero, his title suggesting that he is writing from personal experience, being a member of the military himself, no doubt having intimate knowledge of fortresses. The book is dedicated to his highness Giovanni d’Austria (John of Austria) a noble and military leader himself. Dedicating books to important personalities was common at the time and doing so to a famous admiral was surely fitting.
The book contains many technical details on the arithmetic rules fortifications are based upon. The only illustrations in the book are technical diagrams showing the proper geometric construction of fortresses. This is fitting with the educational nature of this book.
Captitan Ruggieros goal with this book was no doubt to preserve his knowledge of fortresses, both furthering their future development as well as preserving his own legacy as a true military expert.
There is a table of contents in the back of the book which alphabetically lists the topics touched on in the book. For a technical book such as this this type of table of contents is better than simply listing the different chapters as it allows the readers to look up different topics without needing to know the chapter they are in.
