Inventioni di Gio. Battista Isacchi da Reggio, nelle quali si manifestano varij secreti, & vtili auisi a persone di gverra, e per i tempi di piacere
Inventioni is a 1579 Italian military and recreational treatise by Giovanni Battista Isacchi of Reggio, printed in Parma by Seth Viotto for soldiers and men of leisure. Its woodcut plates show a rotated emblem, a fortress with bastions and cannon, a waterwheel-driven machine, and a turreted wooden structure, drawn in plain outline with dense, unornamented line work that a designer could borrow for schematic or period-style diagrams.
