Geometry & Perspective

When scanning in the images for the entry below, I noticed a couple of small geometrical illustrations in Mauriès’ book that I had previously overlooked. These were taken, I read, from a work entitled Geometria et Perspectiva, by one Lorenz Stoer (also spelt Stöer, and Stör), which was published in Augsburg, in 1567, the year before the appearance of Jamnitzer’s Perspectiva Corporum Regularium in the rival Bavarian city of Nuremburg.
