In Italy the study of grammar, with all that it included, was established in tradition, and also was regarded as a necessary preparation for the study both of law and medicine. Even in the eleventh century these professions were followed by men who were “grammarians,” a term to be taken to mean for the early Middle Ages the profession of letters. In the eleventh century, a lawyer or notary in Italy (where there were always such, and some study of law and legal forms) needed education in a Latinity different from the vulgar Latin which was turning into Italian. A little later, Irnerius, the founder of the Bologna school, was a teacher of “grammar” before he became a teacher of law.[299] As for medicine, that appears always to have been cultivated at least in southern Italy; and a knowledge of grammar, even of logic, was required for its study.[300] The survival of medical knowledge in Italy did not, in means and manner, differ from the survival of the rest of the antique culture. Some acquaintance had continued with the works of Galen and other ancient physicians; but more use was made of compendia, the matter of which may have been taken from Galen, but was larded with current superstitions regarding disease. Such compendia began to appear in the fifth century, and through these and other channels a considerable medical knowledge found its way to a congenial home in Salerno. There are references to this town as a medical community as early as the ninth century. By the eleventh, it was famous for its medicine. About the year 1060 a certain Constantine seems to have brought there novel and stimulating medical knowledge which he had gained in Africa from Arabian (ultimately Greek) sources. Nevertheless, translations from the Arabic seem scarcely to have exerted much influence upon medicine for yet another hundred years.[301]
