In my post above, the link to the painting/drawing/whatever of Celestine V has geometric figure (pentagram?) superimposed on it to show angle relationships in image. Also - it has a different title than the one you know of! Maybe inquireing of the Louvre with that title will yeild results? That site has many of the images assciated with this mystery.
