Papercraft Ideas (440 years too late)

I found a gem of a book up in Paley that is a facsimile of the original 1569 copy in Italian. The book is called La Pratica Della Perspettiva and it is by one Daniel Barbaro. While much of the book focuses on perspective there are some fascinating papercraft-like constructions that I scanned to share with you below. Google pales in comparison to some of the gems that are waiting to be found in Paley. If you haven't poked around up there recently, do yourself the favor of exploring. There is a book with similar diagrams written by Albrecht Durer from 1525 entitled, "The Painter's Manual." I could find neither of these books online but they are just collecting dust up in the Library. Great stuff.
