At this point, however, agreement ceased. The question of illness was beset with difficulties. It was agreed that a nun might leave her house, if she suffered from some contagious disease which threatened the health of her sisters[1124], but opinions differed as to whether any relaxation was to be allowed in less severe cases, when only her own health was in question. The visitors sometimes issued licences for nuns to leave their houses in order to recruit their health; thus in 1303 Josiana de Anelaby, Prioress of Swine, had licence to absent herself from her house on account of ill-health[1125], in 1314 Archbishop Greenfield licenced a nun of Yedingham, who was suffering from dropsy, to visit friends and relatives with honest company, for the sake of improving her health[1126] and in 1368 Joan Furmage, Abbess of Shaftesbury, actually received a dispensation to leave the abbey for a year, and reside in her manors, for the sake of air and recreation[1127]. It is significant that the _Novellae Definitiones_ of the Cistercian Order in 1350 strictly forbade nuns to go to the public baths outside their houses, which shows that they had been in the habit of doing so[1128]. But strict reformers were always opposed to such licences, and the specific prohibition of exeats for purposes of cures and convalescences was common in the sixteenth and seventeenth centuries, when the practice had become almost universal in France[1129]. Again there was some difference of opinion as to whether a nun might leave her house, in order to enter one professing a stricter rule. Such a desire was in theory laudable and by Innocent III's decretal _Licet_ the principle was laid down that a bishop was bound _de jure_ to grant leave for migration "sub praetextu majoris religionis et ut vitam ducant arctiorem," as long as the motive of the petitioner was love of God and not merely _temeritas_[1130]. But _temeritas_ was often to be suspected; women, as St Francis de Sales complained, were full of whimsies[1131]; ennui, fancy, a craving for change, a friend in another house, might masquerade as a desire to lead a stricter life elsewhere. Moreover a nun who desired to remove herself was not unlikely to encounter opposition from her own convent. An interesting case of such opposition occurred at Gracedieu in 1447-8. Margaret Crosse, a nun of that house, desired to be transferred to the Benedictine Priory of Ivinghoe "of a straiter order of religion and observance, not for a frivolous or empty reason, but that she may lead a life altogether and entirely harder." She obtained letters of admission from the Prioress of Ivinghoe, but when she came to ask for leave to migrate, the Prioress and Convent of Gracedieu refused to release her from her obedience and confiscated the letters. Bishop Alnwick then wrote to Gracedieu, requiring the Prioress either to let her go, or to furnish him with a reason for their refusal. The Prioress and Convent replied with some acerbity.
