Hernin

Saint Hernin was a hermit from Britain who lived in Brittany and is honoured as the patron of the village of Locarn. Western books also call him Heman.

By tradition he crossed the sea in 528, in the time of the Breton emigration to Armorica, and settled in the parish of Duault, in the place where Locarn would later rise. The local lord, the lord of Quélen, received him on his land and asked him to mark out his hermitage with a ditch, within a single day. Hernin traced a ditch half a league around, dragging his staff along the ground.

He spent his whole life there and reposed around 535. The people buried him in his hermitage, and a large stone marked his tomb. Breton tradition tells of miracles after his death, and a church was built on the site of the hermitage. At Locarn two of his relics are kept, an arm reliquary and a medieval bust reliquary, and on the Sunday after 1 May a pilgrimage called a "pardon" is held.

He is commemorated on 15 September, as a saint of the undivided Church, by the New Calendar.
