Tractatus perutilis et completus de fractura cranei
A 1535 Venetian medical treatise by Jacopo Berengario da Carpi on skull fractures, printed by Giovanni Antonio de Nicolinis da Sabbio for the publisher Giovanni Battista Pederzano, written for surgeons and physicians. Its woodcut pictures show surgical instruments in plain outline, a rod-like handle with a knob or disc at one end and a flattened, serrated or spoon-shaped blade at the other, drawn without shading or background so the shapes read clearly for designers studying early tool form.
