taught them to perform the principal solemnity after the Catholic and apostolic manner;’ and Bede adds, ‘The monks of Hii, by the instruction of Ecgberct, adopted the Catholic rites, under Abbot Dunchad, about eighty years after they had sent Bishop Aidan to preach to the nation of the Angles.’[351] It is rarely, however, that, when a change is proposed in matters of faith or practice, a Christian community is unanimous, and there is always an opposing minority who refuse their assent to it. So it must have been here, for in the same passage in which Tighernac notices the adoption of the Catholic Easter in 716 he adds that Faelchu mac Dorbeni takes the chair of Columba in the eighty-seventh year of his age, and on Saturday the 29th of August; while he records the death of Abbot Duncadh in the following year.[352] We have here again a schism in the community; and no sooner does Abbot Duncadh with his adherents go over to the Roman party, than the opposing section adopt a new abbot. [Sidenote: A.D. 717 Expulsion of the Columban monks from the kingdom of the Picts.] The greater part, if not the whole, of the dependent monasteries among the Picts seem to have resisted the change, and to have refused obedience to the decree which Bede tells us King Naiton had issued, when ‘the cycles of nineteen years were forthwith by public command sent throughout all the provinces of the Picts to be transcribed, learned and observed;’ for we are told by Tighernac that in 717, when Abbot Duncadh had died and Faelchu remained alone in possession of the abbacy, the family of Iona were driven across Drumalban by King Naiton. In other words, the whole of the Columban monks were expelled from his kingdom;[353] and there is reason to think that Faelchu had been at the head of one of these dependent monasteries in the territories of the northern Picts.[354] It is possible that the monks of the monasteries recently established among the southern Picts by Adamnan may have conformed; but those of the older foundations, such as Abernethy and _Cillrigmonadh_, or St. Andrews, were probably driven out; and thus with the expulsion of the family of Iona terminated the primacy of its monastery over the monasteries and churches in the extensive districts of the east and north of Scotland which formed at that time the kingdom of the Picts. ----- Footnote 252: Exceptis duobus populis, hoc est, Pictorum plebs et Scotorum Britanniæ, inter quos utrosque Dorsi montes Britannici disterminant....
