The canonical St. Gereon was a martyred soldier who had his head chopped off. In the usual perverse way of saints, this makes him the patron in charge of migraine headaches (you invoke him to ward them off.)
I still don't know what this thing is, but I think its head hurts.
Another of the uber mixed media, digital/traditional pieces. (They start digitally, get printed, sealed to board, and worked over with a variety of other media.) The original is 12 x 16 and for sale, prints can be ordered directly from Red Wombat Studio at [link]
