Corona imperiale dell' architettura militare
Corona imperiale dell'architettura militare is a 1618 Venetian treatise on fortification, written by Pietro Sardi and Gaspare Grispoldi and published at the author's own expense for military engineers and patrons. Its pictures are plain line plans of star-shaped bastioned forts, with ground plans labelled by letters and scale bars in feet, offering a designer clear geometric diagrams of star and polygon layouts.
