Over a decade ago, conservationists working in the early-medieval St Cadoc’s Church at Llancarfan in South Wales painstakingly chipped away 27 layers of paint and whitewash to uncover extraordinary vivid images of the Seven Deadly Sins. First to be unveiled was “Gula”: Gluttony or Greed, showing a devil indulgently pouring ale over the head of a corpulent figure with a monastic hairdo who is guzzling from a bowl. It is thought that the images gave moral guidance to illiterate parishioners from the 15th century, until they were whitewashed by Protestants, keen to hide Catholic decoration and ideas.
