We forbid on pain of excommunication any nun or sister to go outside the bounds of the monastery until we have made some ordinance concerning enclosure. Item let no one be received as nun or sister until we have enquired more fully into the resources of the house. Item we order the abbess to remove all secular women and to receive none henceforth as boarders in their house. Item let her permit no secular clerk or layman to enter the cloister to speak with the nuns[1091].

But the most detailed information as to the efforts of a conscientious bishop to enforce Boniface VIII’s decree in England is contained in the Register of Bishop Dalderby of Lincoln. Dalderby was a new broom in the diocese and he determined to sweep clean. On June 17th, 1300, he directed a mandate to the archdeacons of his diocese ordering each to associate with himself some other mature and honest man and to visit the religious houses in his own archdeaconry, explaining the terms of the new bull intelligibly to the nuns and ordering them to remain within their nunneries and to permit no one to enter the precincts contrary to the tenour of the decree, until the Bishop should be able to visit them in person; the heads of the houses were to be specially warned to carry out the decree and for better security a sealed copy of it was to be deposited in each house by the commissioners[1092].

In the course of the next two months Dalderby visited, either in person or by commissioners, Marlow, Burnham, Flamstead, Markyate, Elstow, Goring, Studley, Godstow, Delapré (Northampton) and Sewardsley[1093]. At each house the bull was carefully explained to the nuns in the vulgar tongue, they were ordered to obey it and a copy was left with them. But this campaign was not unattended with difficulties. The nuns were bitterly opposed to the restriction of a freedom to which they were accustomed and which they heartily enjoyed, and an entry in Dalderby’s Register, describing his visitation of Markyate, shows that even in the middle ages a bishop’s lot was not a happy one:

On July 3rd, in the first year [of his consecration], the Bishop visited the house of nuns of Markyate and on the following day he caused to be recited before the nuns of the same [house] in chapter the statute put forth by the lord Pope Boniface VIII concerning the enclosure of nuns, explained it in the vulgar tongue and giving them a copy of the same statute under his seal, ordered them in virtue of obedience henceforth to observe it in the matter of enclosure and of all things contained in it, and especially to close all doors by which entrance is had into the inner places of their house and to permit no person, whether dishonest or honest, to enter in to them, without reasonable and manifest cause and licence from the person to whom [the granting of such a licence] pertains. Furthermore he specially enjoined the Prioress to observe the said statute in all its articles and to cause it to be observed by the others. But when the Bishop was going away, certain of the nuns, disobedient to these injunctions, hurled the said statute at his back and over his head, and as well the Prioress as the convent appeared to consent to those who threw it, following the bishop to the outer gate of the house and declaring unanimously that they were not content in any way to observe such a statute. On account of which, the Bishop, who was then directing his steps to Dunstable, returned the next day and having made inquisition as to the matters concerned in the said statute, imposed a penance on four nuns, whom he found guilty and on the whole convent for their consent, as is more fully contained in his letters of correction sent to the aforesaid house.

Afterwards he sent letters to the recalcitrant convent warning them for the third time (they had already been warned once by the Official of the Archdeacon of Bedford and a second time at the visitation which has just been described) to keep the new decree, on pain of the major excommunication, from which only the Pope could absolve them[1094].

There was opposition at other convents, too, though we hear of no more attacks on the episcopal shoulders. On August 19th Dalderby wrote as follows to Master Benedict de Feriby, rector of Broughton, Northants (a church in the presentation of the Abbess and Convent of Delapré):

It has come to our ears, by clamorous rumour, that some of the nuns of our diocese, spurning good obedience, slackening the reins of honesty and shamelessly casting aside the modesty of their sex, despise the papal statute concerning enclosure directed to them, as well as our injunctions made to them upon the subject, and frequent cities and other public places outside their monasteries, and mingle in the haunts of men;

he proceeded to order Feriby to visit nunneries wherever he considered it expedient to do so, and to punish those who were guilty of breaking the statute, signifying to the Bishop, by a certain date, the names of all who had been accused of doing so, whether they had been found guilty or not[1095]. This mandate is no doubt in part explained by two other letters which he dispatched on the same day; one of them was directed to the Archdeacon of Northampton and set forth (in language which often repeats verbatim the phrases of the papal bull) that at the Bishop’s recent visitation of Delapré (Northampton) he had found three nuns in apostasy, having cast off their habits after being a long time professed, and left their house to live a secular life in the world[1096]. The other letter contains a sentence of the greater excommunication against a nun of Sewardsley, for similar conduct[1097]. These cases of apostasy were less rare than might be imagined; Dalderby had to deal with two others during his episcopate, one at St Michael’s, Stamford[1098], and the other at Goring[1099]; and during the rule of his predecessor Sutton three nuns had escaped from Godstow and one from Wothorpe[1100]. They illustrate the undoubted truth that it was only the existence (already in the thirteenth century) of very grave disorders, which led reformers like Ottobon, Peckham and Boniface VIII to “beat the air” with such severe restrictions.

These three documents, the Constitutions of Ottobon and of Peckham and the Bull Periculoso, were the standard decrees on the subject of the claustration of nuns in England and were used as a model by visitors in the thirteenth and fourteenth centuries. William of Wykeham, for example, in the exceptionally full and formal injunctions which he sent to Romsey and to Wherwell in 1387 continually refers by name to Ottobon and to Peckham, and the wording of the Bull Periculoso is followed verbatim in the mandate directed by Bishop Grandisson of Exeter to Canonsleigh in 1329 and in the commission sent by his successor Bishop Brantyngham to two canons of Exeter in 1376, concerning the wanderings of the nuns of Polsloe. But a study of the visitation documents of the thirteenth and fourteenth centuries makes it clear that the nuns never really made any attempt to obey the regulations which imposed a strict enclosure upon them; and that the bishops upon whom fell the brunt of administering Periculoso themselves allowed a considerable latitude, directing their efforts towards regulating the conditions under which nuns left their convents, rather than to keeping them within the precincts. Le mieux est l’ennemi du bien and the steady opposition of the nuns forced a compromise upon their visitors. The canonist John of Ayton, reciting the decrees of Ottobon and of Boniface, with their injunction that bishops shall “cause them to be observed,” exclaims

Cause to be observed! But surely there is scarce any mortal man who could do this: we must therefore here understand “so far as lieth in the prelate’s power.” For the nuns answer roundly to these statutes or to any others promulgated against their wantonness, saying “In truth the men who made these laws sat well at their ease, while they laid such burdens upon us by these hard and intolerable restrictions!” Wherefore we see in fact that these statutes are a dead letter or are ill-kept at the best. Why, then, did the holy fathers thus labour to beat the air? Yet indeed their toil is none the less to their own merit; for we look not to that which is but to that which of justice should be[1101].
