The earliest examples of anything like ornament in Scottish churches within the historic period are undoubtedly the outcome of the Roman influence introduced under the Normans. We have already referred to the effects of early Roman influence at St. Regulus; and the next earliest building, the date of which is thought to be recorded, is the Reilig Oran at Iona (_q.v._), a simple single-chambered structure, with a west doorway containing Norman ornament. This is said to have been erected by Queen Margaret before 1093.[50] The chapel in Edinburgh Castle bearing St. Margaret’s name is also attributed to her, and is supposed to have been erected during her lifetime, or shortly afterwards. It would, in that case, be the first example in Scotland of a church terminating with an eastern apse (which, however, is square on the exterior). Whether these buildings were actually erected in Queen Margaret’s lifetime or not, they certainly belong to a period not long subsequent. The life of that Queen and Saint marks the period of transition in Scotland from the old system to the new, not only in building, but in every other department. Edgar Aetheling, the heir of the old Saxon kings, having been driven out by the Conqueror, found refuge, along with his mother and sisters, in the Court of his relative, Malcolm Canmore. There Margaret, having become Malcolm’s wife, soon introduced many of the reforms and ameliorations she had learned in England. Particularly, she gave a distinct impetus to the Roman influence, then very strong in the South, and encouraged the hosts of Saxon refugees who now crowded to Scotland, bringing their advanced notions with them. The same tendency was manifested by Margaret’s sons, Edgar and Alexander, who followed her footsteps in endeavouring to assimilate the Scottish Church to that of England. It was King Alexander who, being driven by a storm on the Island of Inchcolm, in the Frith of Forth, was rescued and sustained by a hermit, who then occupied a primitive cell, built on the island, similar to those of the Columbans above referred to. The king vowed, in thankfulness for his deliverance, to found a monastery on the spot, and in 1123 he here introduced a colony of Canons Regular. He also endeavoured to bring the Episcopacy of St. Andrews into conformity with the Roman model. Under Alexander,[51] Turgot, the Prior of Durham, and biographer of St. Margaret, was appointed to the long vacant See of St. Andrews. This king also founded the Bishopric of Moray, and restored that of Dunkeld. In the former wild Diocese the churches of Birnie, Spynie, and Kinedor appear to have existed, but it was not till 1203 that Bricius, the sixth bishop, was able to fix his cathedral at Spynie.
