The see was divided by Theodore, Archbishop of Canterbury, in 669 into those of Elmham and Dunwich; and these again were united under Wildred in 870, and the see fixed at Elmham, and where it remained till 1070, when Herfast, a chaplain of William the Conqueror's, moved his see to Thetford.

Now, about this time, when Herbert was abbot of Ramsey and Sewer to William Rufus, the see of Thetford was vacant, and Herbert gave the king to understand that if he was appointed to the vacant bishopric, and his father made Abbot of Winchester, he was willing and able to pay for such preferment a sum of £1900: a part of his accumulated savings, no doubt, and a very large amount for that time.

William II. made these appointments, and the sum mentioned was paid into the royal treasury; but the bishop found that he had attained his end at a cost other than he had reckoned on; public opinion in those days was quite as powerful a force as it is now, though the channels along which its force could be felt and its strength find expression were limited. Indignation was rife, and monkish versifiers and chroniclers protested in lines more or less uncomplimentary, and more or less forcible, their loathing of such sin of simony.

Now it is probable that, in expiation of this transgression, Herbert came to build Norwich Cathedral. It is certain that he almost at once repented. In after years, in his letters, he says, "I entered on mine office disgracefully, but by the help of God's grace I shall pass out of it with credit."

In Dean Goulburn's admirable monograph on the cathedral many of Herbert's letters are given, and these alone would go to stamp him as a wonderful man. His conscience was awakened by the popular outcry against his sin of simony, he plunged into his new duties at Thetford with ardour in the vain hope of distraction, but failed to find that consolation he had hoped to; and so about 1093 he determined on a visit to Rome to tender his resignation and confess his sin to Pope Urban. He journeyed to Rome and was kindly received, and the absolution he desired readily granted. The Pope was glad to see an English bishop come to him for advice, and in granting him absolution he strengthened considerably his claim to be regarded as head of the English Church.

This lengthy preamble may seem somewhat unjustifiable, but if we are to study any building aright, and if we are to interpret in any measure its meaning and symbolism, it cannot wholly be done on any line of abstract aestheticism or archaeological instinct, however intuitive it may be: we must in some measure think of the builders of old times and of the influences which with them produced its inception and have left it to come down the ages to us.

It is interesting to note that Herbert's early French training influenced him in the planning of the beautiful eastern termination to his cathedral, and the grand sweep of the procession path. Similar apsidal terminations, of slightly later date, once existed at Ely, and still remain in a modified form at Peterborough.

The old tribunal arrangement of presbyters' seats with the central bishop's throne facing west, which was part of Herbert's first plan, no doubt may safely be accredited to the influence of his journey to Rome, and where he may have become familiar with what was the usual basilican arrangement.

Herbert returned to England, penitent and forgiven for his sin, and it is probable that the Pope had laid on him, as a penance, an injunction to build churches and found religious houses, and that with the remainder of his wealth he determined to transfer the see from Thetford to Norwich and to build in the latter place his cathedral church. It would also have been in compliance with the decree of Lanfranc's Synod. The see was transferred on the 9th of April 1094, and Herbert was consecrated on the same day by Thomas, Archbishop of York.

Norwich was then an important town; in the Middle Ages it ranked as the second city in the kingdom. Its prosperity was chiefly due to its large trade in wool. It is a moot point whether the town was ever a settlement of the Romans, no traces of such occupation having ever been discovered. The castle mound, no doubt, formed some part of the earthworks of an earlier stronghold. The word Norwich is probably of Norse origin, meaning the north village or the village on the North Creek ("wic"—i.e. a creek). The city stood on a tidal bay in 1004, in which year the Danes under Sweyn completely devastated and ruined the town in revenge for the massacre of their countrymen by Aethelred the Unready two years before. So that the history of the town of Norwich, as we now know it, may be said to have started directly after this.
