When taking an art appreciation course years ago there was a particular painting we studied showing a son being "sworn in" as a judge while in the lower portion of the painting the father who was the judge before him was being skinned alive. The point of the painting was to show what happens when someone fails to perform their duties with honesty and integrity. The painting was 13th or 14th century. I have never seen the painting again. I would very much like to know the name of the painting and where to buy a copy. Any help appreciated. Thanks
