The next question that arises is: What was the point of contact between Ireland and Italy? As in England and Normandy we shall, I believe, find it in the first missions. The first Irish missionary was doubtless St. Patrick, A.D. 373-464, who has been taken as the sign and symbol of Celticism. Yet he was not an Irishman by birth. His father was a Christian named Calphurnius, his mother was niece to St. Martin of Tours; he was consequently of continental origin. His birthplace was Nempthur near Dumbarton, and while yet a boy he was carried a prisoner to Ireland, and the heathendom there appealed so strongly to his feelings, that after his release he was haunted by visions foretelling his future mission to convert Ireland. Pope Celestin I. gave him his mission in about A.D. 430, and he settled in Armagh, where he laboured more than thirty years converting and baptizing both kings and people. He founded schools and built churches. Probably the first worship was conducted in the open air, where a cross was set up, as by the English missionaries. The cross was of the Byzantine form used at that time in Italy; but on its adoption by the northern saint-missionaries it became known in Britain as the Irish cross. The ancient Italian one, once in the Forum at Rome, is of identical style, though of earlier date. St. Patrick's influence remained and spread. Many of his followers in the ministry made the pilgrimage to Rome which he had made, and so great was the fame of sanctity of these Irish preaching brethren, that they were reverenced in Italy even more than in their native land. S. Fredianus became Bishop of Lucca, and Columban was Abbot of Bobbio. It is to these later missionaries rather than to St. Patrick himself that we must look, as having introduced Italian or Comacine architecture into Ireland. That they were addicted to church-building is evident from their at once setting to work wherever they went; S. Fredianus building a church and monastery at Lucca; St. Columban doing the same at Bobbio.
