The organization of the department of women's diseases at Salerno, under the care of women professors, and the granting of licenses to women to practise medicine, is not so surprising in the light of this tradition among Greeks and Romans, taken up with some enthusiasm by the Christians. We are not sure just when this development took place. The first definite evidence with regard to it comes in the life of Trotula, who seems to have been the head of the department. Some of her books are well known, and often quoted from, and she contributed to a symposium on the treatment of disease, in which there are contributions, also, from men professors of Salerno at the time. She seems to have flourished about the middle of the eleventh century. Ordericus Vitalis, a monk of Utica, who wrote an ecclesiastical history, tells of one Rudolph Malcorona, who, in 1059, came to Utica and remained there for a long time with Father Robert, his nephew. "This Rudolph had been a student all his life, devoting himself with great zeal to letters, and had become famous for his visits to the schools of France and Italy, in order to gather there the secrets of learning. As a consequence he was well informed not only in grammar and dialectics, but also in astronomy and in music. He also possessed such an extensive knowledge of the natural sciences that in the town of Salerno, where, since ancient times, the best schools of medicine had existed, there was no one to equal him with the exception of a very wise matron." This wise matron has been identified with Trotula, many of the details of whose life have been brought to light by De Renzi, in his "Story of the School of Salerno."[11] According to very old tradition, Trotula belonged to the family of Ruggiero. This was a noble family of Salerno, many of the members of which were distinguished in their native town at least, but the name is not unusual in Italy, as readers of Dante and Boccaccio are likely to know. It was, indeed, as common as our own Rogers, of which it is the Italian equivalent. De Renzi has made out a rather good case for the tradition that Trotula was the wife of John Platearius I--so called because there were probably three professors of that name. Trotula was, according to this, the mother of the second Platearius, and the grandmother of the third, all of them distinguished members of the faculty at Salerno.
