As yet the see of Canterbury was the sole archbishopric, and in 678 Archbishop Theodore--already known as an organizer of the episcopate--was invited to the court of Northumbria. With Ecgfrith's approval, but without consulting Wilfrid, he divided the diocese into the three sees of Hexham, York, and Lindsey, answering respectively to the tribal divisions Bernicia, Deira, and the land of the Lindiswaras (Lincolnshire). Wise though this action was, it was naturally resented by Wilfrid, who appealed to the Pope--the first appeal of the kind ever made by an Englishman--and set out himself for Rome. He was destined not to return till 680, and even then to be kept out of his bishopric till 686. Ripon was now in the new diocese of York, but in 681 Theodore constituted yet another diocese, of which he made Ripon the cathedral town. Of =Eadhead, First Bishop of Ripon= (681-686), little is known. Originally a priest at the court of Oswiu, he had accompanied the intruded bishop, Chad, when the latter sought consecration at Canterbury during Wilfrid's absence for consecration in Gaul. Eadhead had afterwards been appointed by Theodore to the see of Lindsey, and was translated thence to Ripon when Lindsey was recovered by the Mercians. His tenure of his new office lasted for five years only, for in 686 Aldfrith, the successor of Ecgfrith, restored Wilfrid--not indeed to his original bishopric of Northumbria, but to a see which combined the lately-formed dioceses of Ripon and York[6]. Eadhead accordingly retired, and there were no more Bishops of Ripon for twelve centuries. To Wilfrid was restored not only his bishopric, but also his monastery of Ripon, which he retained in peace for the next five years. At the end of that time a long dispute arose with Aldfrith, who was veering back to the diocesan partition of Theodore, and Wilfrid, deprived of his see for the third time, crossed over into Mercia. In 703 a synod was held at Austerfield, the King and Berhtwald, Archbishop of Canterbury, being present, when Wilfrid was actually asked to promise that he would cease to act as bishop, that he would accept the partition of Theodore, and that he would retire to Ripon and not leave the monastery without the king's permission. Though he was now a man of seventy, he set out once more for Rome, and this time as before the Pope decided in his favour. Returning to Ripon in 705, he attempted to conciliate Aldfrith's successor Eadwulf, but in vain. In the same year, however, Eadwulf was succeeded by Osred, and presently another synod was held, this time at Nidd, seven miles south of Ripon, when it was decided, in the presence of Osred and the now relenting Berhtwald, that Wilfrid should have the monastery and see of Hexham (resigning York) and the monastery of Ripon, thus restored to him for the second time.
