The vexed question, however, does not concern these schools for novices. It has been the custom, not only of writers on monasticism but also of the man in the street, to assume that the nunneries were almost solely responsible for the education of girls in the middle ages. There was little evidence for the assumption, but it was always made, and until the combined attack made upon it in 1910 by Mr Coulton and Mr Leach it was unchallenged[877]. With the publication of bishops' registers, however, we have something more definite to go upon and it is now possible to come to some sort of conclusion, based on the evidence of visitation injunctions, account rolls and other miscellaneous sources. This conclusion may be summarised as follows. It was a fairly general custom among the English nuns, in the two and a half centuries before the Dissolution, to receive children for education. But there are four limitations, within which and only within which, this conclusion is true. _First_, that by no means all nunneries took children and those which did take them seldom had large schools; _secondly_, that the children who thus received a convent education were drawn exclusively from the upper and the wealthy middle classes, from people, that is to say, of birth and wealth; _thirdly_, that the practice was a purely financial expedient on the part of the nuns, at first forbidden, afterwards restricted and always frowned upon by the bishops, who regarded it as subversive of discipline; and _fourthly_, that the education which the children received from the nuns, so far as book-learning as distinct from nurture is concerned, was extremely exiguous. In fine, though nunneries did act as girls' schools, they certainly did not educate more than a small proportion even of the children of the upper classes, and the education which they gave them was limited by their own limitations[878].
