same scenes, and are derived from the same source, as many of those carved on the tympana and fonts of Norman churches. Such sculptures are found on churches dating from 1135 to 1190, and almost no figure sculpture is found on churches of an earlier date. The subjects carved on the churches are similar to those on the crosses, such as Adam and Eve, David and the lion, Daniel and the lions, hunting scenes, animals, monsters, and symbolic figures derived from the bestiaries. (See Dalmeny below.) The latter figures continued to be used on Gothic structures till a comparatively late date. [Illustration: FIG. 9A.--Island of Oronsay. (From _Scotland in Early Christian Times_.)] [Illustration: FIG. 10.--Kilchoman Cross, Islay.] The sculptured crosses of the East of Scotland thus naturally connect themselves with the current design of the period in other countries. They are no longer the mysterious and unintelligible monuments they [Illustration: FIG. 11.--From Iona.] were once supposed to be. By the able investigations and expositions of the writers above referred to, they are brought into harmony with the general art of Europe prior to the twelfth century, and are shown to hold a prominent place in the artistic history of the country. It is remarkable, notwithstanding the abundance of sculpture on the early monuments, that, until the advent of the Norman influence, scarcely any indication of architectural details or sculpture occurs on the churches of either Ireland or Scotland. The earliest sign of decoration on buildings in Ireland is seen in the form of a cross, composed of five white pebbles, inserted over the doorway, in the dark stone of which the beehive cells of Ardoilean are built. Some of the round towers contain very early instances of symbolism in the Celtic cross carved on the lintel, while late examples (such as Brechin) show a further advance in the introduction of a Crucifixion on the lintel, and other figures on other parts of the doorway. The carving of the cross on the above and other lintels is probably symbolic of the blood of the lamb which was struck on the doorposts of the Israelites in Egypt at the Passover.[42] EARLY ECCLESIASTICAL STRUCTURES IN SCOTLAND. The ecclesiastical structures of the early centuries which still survive in Scotland are of the type of the stone erections above described in the monasteries of Ireland. The beehive huts and oratories of the parent eremitical establishments in the latter country are represented by a few similar collections of structures which yet remain in the remote islands and distant parts of Scotland. Groups of dry-built beehive huts (or the remains of them), surrounding one or more primitive churches, can still be pointed to in several localities. These are surrounded with the wall or cashel which was always present around the Irish monasteries.
