Saint Josse (traditionally 600–668), to give him the French name by which he is most recognizable, or Saint Judoc in Breton, was a seventh-century Breton noble who sought the protection of Aymon, a predecessor of the counts of Ponthieu, to live as a hermit and renounce the crown of Brittany, in a place then called either Sidraga or Schaderias or Runiacum, located in the coastal forest near the mouth of the River Canche. He travelled to Rome along the via Francigena, returning safely shortly before his death. Saint Josse has his feast-day on 13 December.
