Caidocus, Saint apostle of the Morini, was a disciple and companion in travel of St. Columban. He and an associate, Fricoreus, seem first to have gone to Lower Germany to teach the Gospel; but, being driven from that country, they came into Ponthieu, in Picardy.. Being roughly treated there, they were about to give up their mission, when, a young nobleman, Richarius, received them into his house. Under their direction he retired from the world, and built the monastery of Centula, where St. Caidocus remained until his death, about A.D. 640, and was buried within its precincts. He is commemorated on Jan. 24. SEE CAMTI.
