La metoposcopia, ouero, Commensuratione delle linee della fronte
A 1629 Venetian treatise on metoposcopy, the reading of character from lines on the forehead, by Ciro Spontone, printed by Evangelista Deuchino. Its pictures are small woodcut heads of bearded and balding men in profile and three-quarter view, with the forehead lines drawn as hatched strokes. A designer could take from them a compact vocabulary of engraved character types, with the hatching used to model faces and to mark the brow.
