These are some remarkably beautiful and illuminating works. It’s not your standard “Kilroy wuz here” stuff, although names found have found, and it’s definitely not the bawdy libels of Roman Pompeii. They are line drawings, some abstract, some of people, demons, ships and crosses. Circles are also a popular theme. It’s social history, contributions of the regular parishioners who attended church but couldn’t afford to leave their mark by sponsoring rich vestments, dazzling stained glass or soaring bell towers."
