Esemplare del'disegno in gratia Dei : principianti nell'arte della pitura et scultura posto in luce nouamente
An illustrated drawing manual printed in Rome in 1650 by an unnamed publisher, teaching beginning painters and sculptors how to draw the features of the face. Its engraved plates break down eyes, noses, mouths and profile heads into separate studies for students to copy. For a designer the pages offer a clear, systematic model for rendering features with fine parallel hatching and crisp contour lines.
