abbot. Born in South Wales, he was a disciple of Samson and a companion of Austell, who migrated from Wales to Brittany through Cornwall, where they founded churches in the same neighbourhood. Mewan founded one monastery in the forest of Broceliande and another in the place now called Saint-Méen, where his Life was written about 500 years after his death. The cult of Mewan spread all over France and pilgrimages to his shrine at Saint-Méen were formerly numerous. In England he is the patron of St Mewan and perhaps Mevagissey (Cornwall). Glastonbury claimed some of his relics; his feast was kept at Exeter, as well as in Cornwall, on 21 June.
