The earliest dedications were probably those to St. Ninian and St. Columba, St. Brigid, and St. Tredwell. It may be significant that in the south parish of South Ronaldsay, where in all probability the companions of St. Columba would make their first landing in Orkney, there were no fewer than three chapels dedicated to him.[5] The sculptured monuments furnish us with three collateral lines of inference, tending to the same conclusion. These inferences are derived from the inscriptions, the ornamentation, and the symbols of the monuments. Two of these monuments bear inscriptions in the Ogham character, a style of cryptographic writing characteristic of the early inscribed stone monuments of Ireland, but occurring also in Cornwall, in Wales, and in Scotland. One of these two was found near the ancient church of Culbinsbrugh, in the island of Bressay in Shetland. It is a slab of chlorite slate, 4 feet in length, about 16 inches wide at the top, tapering to a little less than a foot at the bottom, and about 1¾ inch thick. It is sculptured on both sides in low relief, and the inscription is incised on the edges of the stone. On one of its sculptured faces it bears the Christian emblem of the cross, and among the figures sculptured on it are those of two ecclesiastics with pastoral staves (see Plates). The other inscribed stone was found by Dr. William Traill in the Pictish Tower or “Broch” of Burrian, in North Ronaldsay in Orkney. The inscription scratched on it has not yet been deciphered. It also bears the Christian emblem of the cross. The association of the cross with these Ogham inscriptions[6] points to a period anterior to the Norse occupation of the islands.

Showing the other side and Ogham inscription on edge.] In examining the characteristics of the art of these monumental stones, we are guided to similar conclusions. The Bressay stone bears none of the symbols peculiar to the Scottish monuments, and in its artistic features it comes nearer to some of the Irish than to the general style of the Scottish sculptures. It is sculptured in low relief, while all the Orkney examples are merely incised. But some of the forms of their ornamentation are also characteristic of the art of the illuminated Irish manuscripts of the 7th and 8th centuries, and others are equally characteristic of the art of the bronzes of what has been styled the late Celtic period.
