Another form of woman's work that came to prominence during the century was the service in hospitals. While the records of the hospitals of the Holy Ghost, which under Innocent Third's fostering care spread so widely throughout Europe in this century, are mainly occupied with the institutions of {330} the Brothers of the Holy Ghost, there were many hospitals under the care of women, and indeed there was an almost universally accepted idea, that women patients and obstetrical cases should be cared for by women rather than men. It is easy to make little of the hospitals of this time but any such thought will be the result of ignorance rather than of any serious attempt to know what was actually accomplished. The sisters' hospitals soon usurped the most prominent place in the life of the time and during succeeding centuries gradually replaced those which had been originally under the control of men. It was recognized that nursing was a much more suitable occupation for the gentler sex and that there were many less abuses than when men were employed. The success of these hospitals in gradually eradicating leprosy and in keeping down the death-rate from St. Anthony's fire, or erysipelas, shows how capable they were of accomplishing great humanitarian work. Perhaps the most interesting feature of the story of woman's position during the Thirteenth Century is that at the Italian universities at least, co-education was not only admitted in principle but also in practice, and many women were in attendance at the universities. In the West of Europe this feature did not exist. It is a startling comment on how comparatively trivial a thing may change the course of history, that the lamentable Heloise and Abelard incident at the University of Paris during the Twelfth Century, precluded all subsequent possibility of the admission of women students to the University of Paris. Oxford, it will be remembered, was formed by the withdrawal of students from the University of Paris, and the same tradition was maintained. Cambridge was a grand-daughter of the University of Paris and the French and Spanish universities must all be considered as standing in the relation of its direct descendants. The unfortunate experience at Paris shaped the policy as to the co-education of the sexes for all these. It would have been too much to expect that university authorities would take the risks which had been so clearly demonstrated even with regard to a distinguished professor, and so co-education was excluded.
