monastic life." Piece by piece the sacred story was thus thrown into Caedmon's poem. "He sang of the creation of the world, of the origin of man, and of all the history of Israel; of their departure from Egypt and entering into the Promised Land; of the incarnation, passion, and resurrection of Christ, and of His ascension; of the terror of future judgement, the horror of hell-pangs, and the joys of heaven." [Sidenote: Synod of Whitby] But even while Caedmon was singing the glories of Northumbria and of the Irish Church were passing away. The revival of Mercia was as rapid as its fall. Only a few years after Penda's defeat the Mercians threw off Oswin's yoke and set Wulfhere, a son of Penda, on their throne. They were aided in their revolt, no doubt, by a religious strife which was now rending the Northumbrian realm. The labour of Aidan, the victories of Oswald and Oswin, seemed to have annexed the north to the Irish Church. The monks of Lindisfarne, or of the new religious houses whose foundation followed that of Lindisfarne, looked for their ecclesiastical tradition, not to Rome but to Ireland; and quoted for their guidance the instructions, not of Gregory, but of Columba. Whatever claims of supremacy over the whole English Church might be pressed by the see of Canterbury, the real metropolitan of the Church as it existed in the North of England was the Abbot of Iona. But Oswiu's queen brought with her from Kent the loyalty of the Kentish Church to the Roman See; and the visit of two young thegns to the Imperial City raised their love of Rome into a passionate fanaticism. The elder of these, Benedict Biscop, returned to denounce the usages in which the Irish Church differed from the Roman as schismatic; and the vigour of his comrade Wilfrid stirred so hot a strife that Oswiu was prevailed upon to summon in 664 a great council at Whitby, where the future ecclesiastical allegiance of his realm should be decided. The points actually contested were trivial enough. Colman, Aidan's successor at Holy Island, pleaded for the Irish fashion of the tonsure, and for the Irish time of keeping Easter: Wilfrid pleaded for the Roman. The one disputant appealed to the authority of Columba, the other to that of St. Peter. "You own," cried the king at last to Colman, "that Christ gave to Peter the keys of the kingdom of heaven--has He given such power to Columba?" The bishop could but answer "No." "Then will I rather obey the porter of heaven," said Oswiu, "lest when I reach its gates he who has the keys in his keeping turn his back on me, and there be none to open." The humorous tone of Oswiu's decision could not hide its importance, and the synod had no sooner broken up than Colman, followed by the whole of the Irish-born brethren and thirty of their English fellows, forsook the see of St. Aidan and sailed away to Iona. Trivial in fact as were the actual points of difference which severed the Roman Church from the Irish, the question to which communion
