La sfera di Proclo Liceo
This is a 1573 Italian edition of Proclus's treatise on the sphere, printed in Florence by the Giunti press for astronomy students and scholars. The four pictures are woodcut diagrams of armillary-style spheres on ornate stands, with lettered circles, great-circle lines and shaded bands marking geometric relationships. A designer could take their clean radiating lines, fine linework and decorative scroll bases as models for technical or scientific graphics.
