You can do an image search in google by hitting the camera and uploading the image. My results lead me to the name being, "Mystic Marriage" and that the picture is tied to Christian Mysticism and Thomas Merton. http://en.wikipedia.org/wiki/Thomas_MertonSee if you or your readers can take it from there.
thanks, yeah the wiki page doesn't say much about the image.
You might try getting in touch with Mikeal Parsons at Baylor. I know he has a passion for art. Actually, his wife, Dr. Heidi J. Hornik, teaches Italian Renaissance Art History at Baylor, too.
I believe this was from when Jesus claimed Switzerland.
