Three other witnesses also swore to the tale[134]. Even cases of violent and dangerous madness seem at times to have occurred, judging from a note at Alnwick's visitation of Stainfield in 1440, in which it is said that all the nuns appeared separately before the Bishop, "with the exception of Alicia Benyntone, who is out of her mind and confined in chains"[135]. Lay and ecclesiastical opinion alike condemned another practice, which seems to have been fairly widespread in medieval England, that of forcing into convents children too young to realise their fate, or even girls old enough to resist, of whom unscrupulous relatives desired to be rid, generally in order to gain possession of their inheritance; for a nun, dead in the eyes of the law which governed the world, could claim no share in her father's estate[136]. It is true that influential people, who could succeed in proving that a nun was unwillingly professed, might obtain her release[137]; but many little heiresses and unwanted children must have remained for ever, without hope of escape, in the convents to which they had been hurried, for it is evident that the religious houses themselves did all they could to discourage the presentation of such petitions, or the escape of unwilling members. The _chanson de nonne_, the song of the nun unwillingly professed, is a favourite theme in medieval popular poetry[138]; and dry documents show that it had its foundation in fact. It is possible to collect from various sources a remarkable series of legal documents which illustrate the practice of putting girls into nunneries, so as to secure their inheritance.
