JF Ptak Science Books Quick Post
The fantastic Jesuit Andrea Pozzo published results of his researches on perspective in his Perspectiva pictorum et architectoru (1693),
explaining how he was able to compellingly, unbelievably represent
three-dimensional images on two-dimensional spaces, this image showing
plan and projection and profile, effectively giving you a
three-dimensional cross section of the architectural element…and having them seemingly float in space. His work is just absolutely gorgeous.
