When Constantinople fell into the hands of the Turks in 1453, many of its Greek inhabitants, and particularly those belonging to the more highly educated classes, fled to Western Europe in order to escape from the tyranny of the invaders. Not a few of these refugees brought with them to Italy and France copies of the works of the classical Greek authors, and on this account, as well as because of their willingness to give instruction in their native tongue, they met with a cordial welcome wherever they took up their new abodes. Their arrival in Italy happened at a most propitious time, for the interest in Greek literature was at that period just beginning to develop among Italian scholars. Previously, Greek had been an almost unknown tongue in Italy. Petrarch, for example, is reported to have said in 1360 that he did not know of ten educated men in that country who understood Greek; and there is no evidence to show that the number of such men increased between 1360 and the time when the refugees from Constantinople arrived. Many of the works of greatest importance to physicians--such, for example, as the writings of Hippocrates, of Galen, of Rufus of Ephesus, of Oribasius, of Alexander of Tralles, and of several other classical medical authors of antiquity--were accessible (in the original) only to those who were familiar with the Greek tongue. Consequently the arrival of these refugees from Constantinople constituted a most important event in the history of European medicine.
