First is a 1549 representation of the five Platonic solids by the German graphic artist Augustin Herschvogel (1503-1553). The solid-edge form imitates Leonardo's drawings in Pacioli's Divine Proportion. It is interesting because it appears to associate the Platonic solids with the four ancient elements of Earth, Air, Fire, and Water in a different manner than Plato.
