(5th century (?),
bishop. Cornish tradition makes him the founder and patron of the fishing village near Falmouth which bears his name; Leland said he was a bishop in Brittany and is ‘painted as a schoolmaster’. Topographical evidence points to a close association with Budoc; Doble thinks that both of them were monks and missionaries from Wales who founded monasteries in Cornwall and Brittany, perhaps at Dol. The cult of Mawes in Brittany has always been much more notable than in England or Wales. He settled with some disciples on an island, Cle Modez, near the coast of Léon and had the reputation of being a famous teacher, who was also popularly invoked against headaches, worms, and snake-bite. About sixty churches and chapels in Brittany are or were dedicated to him; his relics were venerated at Quimper, Treguier, Lesneven, and other places, especially Bourges, which claimed that his body had been translated there during the Viking invasions of the 10th century. Feast: 18 November.
