The whole of Ireland is covered with the traces of this great national revival. We may still see on islands, along river-valleys, in lonely fields, innumerable ruins of churches built of stone chiselled as finely as man's hand can cut it; and of the lofty round towers and sculptured high crosses that were multiplied over the land after the day of Clontarf. The number of the churches has not been counted. It must be astonishing. At first they were built in the "Romanesque" style brought from the continent, with plain round arches, as Brian Boru made them about A.D. 1000; presently chancels were added, and doors and windows and arches richly carved. These churches were still small, intimate, suited to the worship of the tribal communities; as time went on they were larger and more richly decorated, but always marked with the remembrance of Irish tradition and ornament, and signed by Irish masons on the stones. There was a wealth of metal work of great splendour, decorated with freedom and boldness of design, with inlaid work and filigree, and settings of stones and enamels and crystal; as we may see in book-shrines, in the crosiers of Lismore and Cachel and Clonmacnois and many others, in the matchless processional cross of Cong, in the great shrine of St. Manchan with twenty-four figures highly raised on each side in a variety of postures remarkable for the time. It was covered with an embroidery of gold in as good style, say the Annals, as a reliquary was ever covered in Ireland. Irish skill was known abroad. A French hero of romance wore a fine belt of Irish leather-work, and a knight of Bavaria had from Ireland ribbon of gold-lace embroidered with animals in red gold.
