First edition. Fiammelli's work on the usefulness or otherwise of fortification stemmed from Machiavelli's debate that their construction showed a ruler's lack of trust in his subjects. Fiammelli, a Florentine mathematician and engineer who worked for the Duke of Parma in the Low Countries, examines all the ramifications of fortifications, showing that good ones are useful but that they have to be used competently to be effective. This is one of several military works that Fiammelli wrote while resident in Rome at the end of his life.
