Renaissance women were, of course, profoundly educated. In a word, we have many phases of feminine education, though with intervals of absolutely negative interest, down the centuries. There had evidently been quite a considerable amount of opportunity, if not of actual encouragement, for women in medicine, both among the Greeks and the Romans, in the early centuries of the Christian era. Galen, for instance, quotes certain prescriptions from women physicians. One Cleopatra is said to have written a book on cosmetics. This name came afterwards to be confounded with that of Queen Cleopatra, giving new prestige to the book, but neither Galen nor Aetius, the early Christian physician, both of whom quote from her work, speak of her as anything except a medical writer. Some monuments to women physicians from these old times have escaped the tooth of time. There was the tomb of one Basila, and also of a Thecla, both of whom are said to have been physicians. Two other names of Greek women physicians we have, Origenia and Aspasia, the former mentioned by Galen, the latter by Aetius in his "Tetrabiblion." Daremberg, the medical historian, announced in 1851 that he had found a Greek manuscript with the title, "On Women's Diseases," written by one Metrodora, a woman physician. He promised to publish it. It was unpublished at the time of his death, but could not be found among his papers. There is a manuscript on medical subjects, bearing this name, mentioned in the catalogue of the Greek Codices of the Laurentian Library at Florence, but this is said to give no indication of the time when its author lived. We have evidence enough, however, to show that Greek women physicians were not very rare.
