Ethelburga, the Queen, and her two children, escorted by Paulinus, fled into Kent, and Paulinus was afterwards presented to the See of Rochester. He was never Archbishop of York (as by some supposed), although the Pope offered that dignity to him; the letter was addressed to Edwin, who was dead before it was delivered. Paulinus died at Rochester October 10, A.D. 644. Cædwallon ruled over Northumbria for only a few years, and his successor, Oswald, who had probably passed some years in the monastery of Iona very early in his reign, sent over to that community for help towards the revival of Christianity in this kingdom. The first priest who was sent returned reporting that the people were impracticable and refused to be converted, whereupon a priest called Aiden was consecrated Bishop, and despatched to Northumbria in the year 635. Oswald did not, as might have been expected, place Aiden at York, but gave to him a small island on the coast of Durham known as Holy Island, and here was founded the abbey of Lindisfarne, which was destroyed by the Danes in A.D. 795; from this centre the missionary work in the North of England emanated. The basilica at York was finished by Oswald, and by erecting other churches and granting lands for the sites of religious houses this King did much to establish the Christian religion in the North. But after eight years of comparative peace Northumbria again passed into pagan hands (see p. 43), and not until Penda in A.D. 655 was defeated and slain did paganism receive its death-blow. Oswy, on gaining this final victory, fulfilled the vow which he had made--that if he was successful in this war he would give twelve sites for as many monasteries, and give his infant daughter to serve the Lord in holy virginity. The monasteries were founded, but none of them appear to have been on the western or Lancashire side of the Pennine Hills. Early in A.D. 665 the bishopric of York was re-established, when Wilfrid was consecrated as Bishop at Compiègne in France; but having delayed his coming to his see for nearly twelve months, he was not a little astonished to find that in the meantime Chad's consecration had taken place and he was already in possession. For a few years only he held the office, and on his retirement to the monastery of Lastingham, Wilfrid took his place. Of the dispute with Theodore, Archbishop of Canterbury, and the temporary expulsion of Wilfrid from the See of York and his subsequent visit to Rome, where he saw the Pope, and obtained from him a decree which was to reinstate him, little need here be said, except that on his return to York, and a "witan" having been called, the Pope's order was treated with scorn by the assembly, and Wilfrid was cast into prison, where he remained for nine months.
