CHAPTER XV.
INFLUENCE OF THE DANISH INVASIONS ON THE CHURCH.
We have seen that in the eighth century there was a decrease of influence in the Columban order, and a corresponding increase in the power of Armagh. The ninth century and the Danish invasions did still more for the diminution of the one and the advancement of the other. The repeated attacks made on Iona itself, and the transference from thence of the leading members of the community with all their most precious possessions was in itself a terrible blow. Kells, the 'new Iona,' never obtained the prestige of the old, and ceased after a time to be considered the mother church of the order. Derry afterwards obtained the pre-eminence: but this shifting of the central authority, accompanied as it was with frequent attacks from the barbarians, could only weaken the influence of the order, and quickly bring to an end that supremacy which it once enjoyed.
A serious dispute arose about this time between the followers of Columba and one of the most powerful of the Irish kings of the ninth century. We are quite in the dark as to how the controversy arose, or what were the questions on either side. We only know that in 814 'the families of Columkill went to Tara and solemnly cursed and excommunicated the king.' There was a time when such a ceremony would probably have cost the monarch his throne.
