Among these were Christine de Pisan, who was a prolific writer on many subjects in both prose and verse, and who, it is said, was the first woman to earn a livelihood by her pen.[50] There were also some of those remarkable women who lectured on law in the University of Bologna, among whom were Bettina Gozzadini,[51] who, some writers will have it, occupied the chairs of law in her _alma mater_ as early as 1236, and the celebrated Novella d'Andrea, of the following century, who frequently acted as a substitute for her father, a professor of canon law in the university, and who, by reason of her varied and profound knowledge, held a prominent place among the most learned men of her time. Both of these noted women were worthy prototypes of that long list of learned Italian women who, during the Renaissance, won such honor for themselves and such undying glory for their country. Not less remarkable were several women of the school of Salerno, who, during its palmiest days, distinguished themselves as teachers, writers and medical practitioners,[52] and the still more remarkable daughters of one Mangord, a professor of Paris, whose daughters taught Sacred Scripture.[53] There were few in number, it is true, but they were the worthy prototypes of those learned and brilliant women who achieved such distinction and glory for their sex during that most interesting period of history known as the Renaissance. WOMAN AND EDUCATION DURING THE RENAISSANCE By the Renaissance we understand not only a phase in the development of the nations of Europe but also that period of transition between the mediaeval and the modern world during which the latent spiritual energies of the Middle Ages developed into the intellectual forces and moral habits of thought which now pervade the civilized world. Various dates are assigned for its starting point. Among them is the fall of Constantinople in 1453, when there was a great influx of scholars from the famed metropolis on the Bosphorus to the Italian peninsula, who brought with them those forgotten treasures of science and literature which were so instrumental in producing that interesting phenomenon known in history as the Revival of Learning. But whatever date be assigned for the beginning of the Renaissance, whether it be the year when Constantinople fell into the hands of the Turk or the fateful millennial year which was to witness the termination of all things, there certainly was never at any period a distinct breach of historical continuity between the old order and the new.
