The first building remained until after the Norman Conquest, a great change having taken place in the meantime. The monks who, with the Bishop, had originally constituted the congregation of St. Cuthbert, had fallen from the rule which was first observed. There was in those days a great tendency among the regular clergy in the Saxon Church to degenerate into a kind of secular clergy. Symeon says those at Durham were neither monks nor regular canons. At Durham, as at Hexham, some members of the congregation were married and had families, and there was springing up at Durham possibly, as there certainly was at Hexham, an hereditary system, son succeeding father; and had the system gone on, there would have arisen a sacerdotal caste, with all the evils attending such a body. The Norman Conquest happily did away with that, as it did with other abuses. It is probable that some remains connected with these married members of the congregation were discovered in 1874, when the foundations of the east end of the old chapter-house, which was so ruthlessly destroyed in 1796, were laid bare. The graves of Bishops Ranulph Flambard, Galfrid Rufus, and William de St. Barbara were met with, each covered with a slab bearing his name--probably not quite contemporary--and in them were found three episcopal rings of gold, set with sapphires, and in the grave of Flambard, the head, made of iron, plated with silver, and the iron ferrule of a pastoral staff, all of which are now preserved in the cathedral library. Below the level of the Bishops’ graves there were found a considerable number of skeletons of men, women, and children, with one of which was deposited the iron head of a spear, having the socket plated with gold. There can be little doubt that these bodies belonged to the married portion of the congregation and their families, who occupied the monastery at Durham from the time of Aldhun to their being dispossessed by Bishop William of St. Carileph.
