Featured on PDR in the collection Solid Objects: 16th-Century Geometric and Perspective Drawings

This sequence of increasingly complex geometrical figures and perspective drawings — collected in a sixteenth-century watercolor manuscript and preserved at the Herzog August Bibliothek in Wolfenbüttel — comes with no author's note, editor's preface, or running commentary. We know very little about its origins. All we have are shapes and color, with the occasional totem (eagle, rooster, and even a putto holding something like a pinwheel) dwarfed by the immensity of lines and angles.
