I was wondering if anyone might be able to help me locate a rather difficult to find 12th century illustration of a battle. I've only seen it in one book, which was part of a twin volume set, in German, about history in the era of the Welfs. The twin volumes have a number of different articles by different authors, and most have numerous illustrations or photographs. Unfortunately, that's the best I have regarding the books.

I remember more about the image in question. It's from a copy of Peter the Lombard's commentary on the Psalms. I believe the illustration is from circa 1160. It's a depiction of knights fighting on foot with sword and shield, an illustration of a battle between the Israelites and the Philistines.

If anyone knows where I can track down this image, I'd appreciate it.
