... Judicael, commonly called Giguel, eldest son of Juthael, became king of Britany about the year 630.  This prince soon after renounced this perishable crown to labour more securely for the acquisition of an incorruptible one, and retired into the monastery of St. Meen, in the diocess of St. Malo, where he lived in so great sanctity as to be honoured after his death with the title of the Blessed Judicael.  When he resigned the crown he offered it to his younger brother Jodoc, called by the French Josse.  But Jodoc had the same inclinations with his elder brother. However, to consult the divine will, he shut himself up for eight days in the monastery of Lanmamiont, in which he had been brought up, and prayed night and day with many tears that God would direct him to undertake what was most agreeable to him, and most conducive to his divine honour and his own sanctification.  He put an end to his deliberation by receiving the clerical tonsure at the hands of the bishop of Avranches, and joined a company of eleven pilgrims who purposed to go to Rome...
