I'm sure you'll agree that nothing says "Lent" better than a prolonged investigation of a magnificent 12th Century Altarpiece - one of, perhaps the best one in existence:
Using this fantastic link, I highly recommend you give some of the panels a few clicks. As explained in the dedication, it arranges the entire Bible typologically - top row is "before the law" (Adam-Moses), bottom row is "under the law" (Moses-Christ) and the middle row which illuminates the top and bottom is "under grace" (Jesus, etc.). You'll get the hang of it. And next time you're in Klosterneuburg, Austria you can check it out in person.
