Much information about the conduct of abbesses and prioresses may be obtained from a study of episcopal registers, and in particular of visitation documents. An analysis of Bishop Alnwick's visitations of the diocese of Lincoln (1436-49) gives interesting results. In all but four houses there were few or no complaints against the head. Sometimes it was said that she failed to dine in the frater or to sleep in the dorter, sometimes that she was a poor financier, and in two cases the charge of favouritism was made; but the complaints at these sixteen houses were, on the whole, insignificant. The four remaining heads were unsatisfactory. The Prioress of St Michael's Stamford was so incompetent (owing to bodily weakness) that she took little part in the common life of the house and regularly stayed away from the choir, dined and slept by herself, though the Bishop refused to give her a dispensation to do so. The administration of the temporalities of the house was committed by Alnwick to two of the nuns, but when he came back two years later one of these had had a child and the other was unpopular on account of her autocratic behaviour. The moral condition of the house (one nun was in apostasy with a man in 1440, and in 1442 and 1445 two nuns were found to have borne children) must in part be set down to the lack of a competent head[245]. The Prioress of Gracedieu was also old and incompetent; her subprioress deposed that by reason of old age and incapacity the prioress has renounced for herself all governance of matters temporal, nor does she take part in divine service, so that she is of no use; but if she makes any corrections, she makes them with words of chiding and abuse.... She makes the secrets of their religious life common among the secular folk that sit at table with her ... and under her religious discipline almost altogether is at an end.
