Baring-Gould’s sources: Dempster's Scottish Menology, Adam King's Kalendar, and that of David Camerarius. Aberdeen Breviary.] The Aberdeen Breviary says: “When the blessed fathers, Columba and Mauricius (Machar), were preaching in Scotland, a very old man named Devinicus also flourished there. He divided the work of the ministry between himself and Mauricius, going to the province of Caithness while Mauricius went to the Piets. S. Mauricius said, * Now again we shall be joined. In life celestial we shall unite for ever and rejoice with Christ. But there is one thing that I desire, that when death comes, my body may be brought hither to be buried.’ The saint agreed, and Devinic went to the people of Caithness preaching the Word. At length Devinic came to die, and told them to take his body to one of the churches of Mauricius, mindful of his old engagement. And this was done. The following night S. Mauricius saw angels descending on the church where the holy body lay, and said, * A guest cometh, to whom we must pay honour but on coming they found not his body, for they who carried it, wishing to rest, had borne it to a place called Crostan. There they held vigil, and then brought it to a place called Banqukory Devynik, where a church was raised in his honour.”

Criech was probably dedicated to this saint, but his name has suffered corruption into S. Teavneck. At Methlich is S. Denick's fair, on the second Tuesday in November. S. Devinick's well is on the opposite side of the Ythan. Bishop Forbes suggests that S. Devinic may be the saint to whom Landevedneck, near the Lizard Point, in Cornwall, is dedicated. But this can scarcely be. The knowledge of the apostle of Caithness could not well have reached Cornwall and Brittany, in which province is also a church with the same dedication, Lan Devenach. The saint commemorated in Cornwall and Brittany is probably S. Dyfynog, son of Medrod ab Cawrdaf ab Caradog, whose church was in Brecknockshire, and his festival February 13.
