The _Abbordoboir_ here spoken of is Aberdour on the north coast of Aberdeenshire, and _Dear_ probably occupied the site of what is now Old Deer, about twelve miles inland from Aberdour. There is every reason for believing in the substantial truth of the narrative. The two saints, probably from the banks of the Ness, came to Aberdour and “tarried there for a time and founded a monastery on the land which had been granted them. In later times the parish church of Aberdour was dedicated to St. Drostan.” One would almost be inclined to suppose, from the manner in which the missionaries were apparently received, that Christianity had been heard of there before; possibly Bede the Pictish mormaer had been converted at the court of King Brude, and had invited Columba to pay him a visit in Buchan and plant the gospel among the inhabitants. Possibly St. Ninian, the apostle of the southern Picts, may, during his mission among them, have penetrated as far north as Buchan. On the side of the choir of the old parish church of Turriff, a few miles west of Deer, was found painted the figure of St. Ninian, which was probably as old as the 16th century. At all events, Columba and his companion appear to have been made most welcome in Buchan, and were afforded every facility for prosecuting their sacred work. The above record doubtless gives us a fair notion of Columba’s mode of procedure in prosecuting his self-imposed task of converting the inhabitants of Alba. As was the case in Buchan, he appears to have gone from district to district along with his missionary companions, seen the work of conversion fairly begun, planted a monastery in a suitable place, and left one or more of his disciples as resident missionaries to pursue the work of conversion and keep Christianity alive in the district.[93] Columba soon had the happiness of seeing the blessings of Christianity diffusing themselves among a people who had hitherto sat in the darkness of paganism. Attended by his disciples he traversed the whole of the Pictish territories, spreading everywhere the light of faith by instructing the people in the truths of the Gospel. To keep up a succession of the teachers of religion, he established, as we have seen, monasteries in every district, and from these issued, for many ages, men of apostolic earnestness, who watered and tended the good seed planted by Columba, and carried it to the remotest parts of the north of Scotland and its islands, so that, in a generation or two after Columba, Christianity became the universal religion. These monasteries or cells were long subject to the Abbey of Iona, and the system of church government which proceeded from that centre was in many respects peculiar, and has given rise to much controversy between presbyterians and episcopalians.
