We frequently receive permission requests for Luca Pacioli's De divina proportione, illustrated by Leonardo da Vinci, of which the Penn State University Libraries hold a facsimile copy.

This book is a facsimile of a work in the public domain, so it is also public domain (i.e., the illustrations are not subject to copyright protection). You are welcome to use them, but we cannot grant you permission under copyright law because we do not hold the copyright (nor does anyone else). When you use them, we would appreciate it if you cited the Pennsylvania State University Libraries as the source of the images, and we suggest also citing where you found them. For an official public statement of our policy on public domain items within our collections, please see the Libraries Copyright Statement.
