A rare discovery was announced this week at St Cadoc’s church in Llancarfan, Vale of Glamorgan — 15th century murals were found under 20 coats of white wash inside the church. This church was built on the site of the original 6th century church of St Cadoc, one of the best known early medieval saints of Wales. The 11th century Life of Cadog gives us a rare glance at pre-Geoffrey of Monmouth legends of King Arthur. Cadog/Cadoc was also reputed to been an associate of St Gildas, St Illtud, St David and several Welsh kings. It is believed that the inside of the church is covered with high quality murals including perhaps one of the oldest depictions of the story of St George and the Dragon.

Lovely to see your interest in the rediscovery of the paintings, Michelle. I interviewed one of the conservators at the unveiling celebrations: http://ladychatandtea.wordpress.com/2011/12/13/fifteenth-century-paintings-uncovered-in-south-wales-church/
All the best, Rachel.
