Medardus

Medardus or Medard (ca. 456–545) was the Bishop of Noyon. He moved the seat of the diocese from Vermand to Noviomagus Veromanduorum in northern France. Medardus was one of the most honored bishops of his time, often depicted laughing, with his mouth wide open, and therefore he was invoked against toothache.
