As early as 791 a council had forbidden the practice and in 1195 another at York decreed, 'In order that the opportunity of wandering may be taken from nuns we forbid them to take the path of pilgrimage.' In 1318 an archbishop of York strictly forbade the nuns of one convent to leave their house 'by reason of any vow of pilgrimage which they might have taken.

If any had taken such vows she was to say as many psalters as it would have taken days to perform the pilgrimage so rashly vowed.'[22] One has a melancholy vision of poor Madame Eglentyne saying psalters interminably through her tretys nose, instead of jogging along so gaily with her motley companions and telling so prettily her tale of little St Hugh.

Such prohibitions might be multiplied from medieval records; and indeed it is unnecessary to go further than Chaucer to understand why it was that bishops offered such strenuous opposition to pilgrimages for nuns; one has only to remember some of the folk, in whose company the prioress travelled and some of the tales they told.

If one could only be certain, for instance, that she rode all the time with her nun and her priests, or at least between the Knight and the poor Parson of a town! But there were also the Miller and the Summoner and (worst of all) that cheerful and engaging sinner, the Wife of Bath.

It is really quite disturbing to think what additional details the Wife of Bath may have given the prioress about her five husbands.
This then was Chaucer's prioress in real life, for the poet who drew her was one of the most wonderful observers in the whole of English literature.
