But it was in the earlier part of his career, before he received the bishopric of Durham in 1099, that he probably began the work at Christchurch with which we are at present concerned.[4] He was succeeded there by Godric, who is called Senior and Patron and afterwards Dean; but Flambard seems still to have exercised some authority over him, illegal probably, but none the less real. We find him granting to Godric, for the work of building, all the offerings made by strangers and pilgrims, and when a canon died his share of the revenues of the college was devoted to the same object, the vacancy not being filled up by the appointment of any new canon. [4] Sir Gilbert Scott, however, thought that the Norman nave of the Cathedral Church at Durham was commenced before Flambard became bishop, and that the new church at Christchurch was begun after that date, so that the work at Christchurch was copied by him from what he found already commenced at Durham when he went there. The length of Godric's tenure of office is uncertain. On his death Henry I. appointed Gilbert de Dousgunels dean, having appropriated to himself the accumulated fabric fund. Henry I. granted the patronage of the church to Richard de Redvers, Earl of Devon, who appointed his chaplain, Peter, a Norman of Caen, dean. This dean seems to have diverted the funds from the work of completing the church, but his successor, Randulphus, carried on the work again, so that in his time the church and the conventual buildings were roofed in. In the time of Hilary, in the year 1150, the secular college of canons was converted into a Priory of Augustinian Canons. This change was made with the consent of Baldwin de Redvers, in accordance with the wishes of Henry of Blois, brother of King Stephen, and at that time Bishop of Winchester, who is well known from the fact of his founding the Hospital of St Cross, near Winchester. Hilary, two years before this change was made, had been consecrated Bishop of Chichester, and subsequently became one of the episcopal opponents of Thomas Becket. Henceforth, until the dissolution in the reign of Henry VIII., the head of the religious community at Christchurch was a prior, who was, according to a charter granted by Richard de Redvers in 1160, elected by the canons. There were, in all, twenty-six priors, and their names have come down to us, but with only the most meagre notices of the architectural work which was carried on by each of them. Extensive, however, it must have been; and from what we see of the church itself, it would seem as if building operations must have been almost constantly in progress.
