on the same subject are taken two of the hymns used by the Church on the festivals of Christmas and the Epiphany.[39] St. Servanus, the first bishop of Orkney, is represented by some as a disciple of St. Palladius, but it is probable that he lived some years later. He was the founder of the monastery of Culross, where he brought up many youths from childhood, and educated them for the sacred ministry. Among these was one named Kentigern, so beautiful in person, and so innocent in manners, that his companions bestowed on him the title of _Mungo_, or the dearly beloved, by which name he is still best known in Scotland. When only twenty-five years of age the people demanded him for their bishop; he was accordingly consecrated by an Irish prelate, and chose for his residence a certain solitary place at the mouth of the river Clyde, the site of the present city of Glasgow. Here he erected a church and monastery, where he lived with his clergy according to the apostolic rule, his diocese extending from the Atlantic to the shores of the German Ocean; and over its vast extent he constantly journeyed on foot, preaching and administering baptism. The throne of the Scottish prince Rydderch the Liberal having been seized by one of his rebellious nobles, St. Kentigern was forced by the usurper to quit the country, and took refuge in Wales, where, after visiting St. David at Menevia, he received from one of the Welsh princes a grant of the tract of land lying between the rivers Elwy and Clywd, where he erected the monastery and school of Llan-Elwy. Local tradition affirms that the name of Clywd was bestowed by him on the stream that bounded his domain, in memory of his old home on the banks of the Clyde. Here he was joined by a great number of followers, among whom he established regular monastic discipline. His rule, however, had some peculiarities in it. He divided his community into three companies, two of them, who were unlearned, were employed in agriculture and the domestic offices, the third, which was formed of the learned, devoted their time to study and apostolic labours; and this last class numbered upwards of three hundred. These again were divided into two choirs, one of whom entered the church as the others left, so that the praises of God at all hours resounded in their mouths. From this college a great number of apostolic missionaries went forth, not only into different parts of Britain, but also to Norway, Iceland, and the Orkney Islands St. Kentigern himself continued to journey about, preaching the faith, silencing the Pelagian heretics, and founding churches. On the restoration of Rydderch, in 544, St. Kentigern was recalled to his see, and left the government of his monastery and school at Llan-Elwy to St. Asaph, his favourite scholar, whose name was afterwards conferred upon the church and diocese.
