Osservazioni intorno alle torpedini
A 1678 Florentine natural history treatise by Stefano Lorenzini on electric rays, published in Florence by Onofri and written for naturalists and anatomists. Its copper-engraved plates show dissections and organs of the torpedo fish, drawn in fine parallel hatching with lettered keys. A designer might take from them the dense crosshatch shading and the diagrammatic labelling typical of early scientific engraving.
