In the West of Scotland, on the other hand, the principal form of cross is the free standing one. In consequence of the invasions of the Northmen, this part of the country was in a great state of disturbance for a long period after the expulsion of the Columbans from the East, and little monumental work seems to have been done.[40] There are, however, a few fragments of free standing crosses at Iona, and one fine specimen at Kildalton, in Islay, which exhibit the same characteristics in their sculpture as the pure Celtic upright slabs of the East. (Fig. 8.) When monumental sculpture was revived in the West, at a considerably later date, its style indicates connection with Ireland rather than with the East of Scotland. Free standing crosses abound, and the upright slabs carved on both sides are rare; the grave slabs being recumbent, like those of Ireland. The symbols peculiar to the East are also entirely wanting. It seems also that the monuments of Argyllshire and the Western Islands (as at Iona, &c.) were influenced by a style of sculpture imported from the Continent, of which examples exist at Durham and Hexham. These “are not Celtic, but a debased local survival of Romanesque forms.”[41] The late Western crosses have, further, this peculiarity, that the circular band round the head of the cross is not cut free, so as to present an independent ring of stone, but forms a solid disc, from which the ends of the arms and top project. (Figs. 9 and 9A.) These crosses generally contain a representation of the Crucifixion, which is almost unknown in pure Celtic work. The carving also ceases by degrees to be distinctively Celtic, and consists generally of scroll work and foliage. (Fig. 10.) These features were adhered to in this region for centuries after the Celtic work of the East had entirely given place to the general Gothic art of the rest of Europe. (Fig. 11.) The monuments of the West thus retain a very special character, the foliage of the designs being unique and original, and in many cases of much beauty. This peculiar design continued as late as the sixteenth century, several good dated examples of that period being still preserved, mixed with debased Gothic features. The architecture of the locality is naturally much influenced by this style, as will be pointed out when Iona is described. It can scarcely be doubted that many of the Scottish sculptured stones are of about twelfth century date. The sculptures on them represent the [Illustration: FIG. 8.--St. Martin’s Cross, Iona.] [Illustration: FIG. 9.--M‘Lean’s Cross, Iona.]
