Nevertheless, the position of the philologists, as such, even where the salary was large, and did not exclude other sources of income, was on the whole uncertain and temporary, so that one and the same teacher could be connected with a great variety of institutions. It is evident that change was desired for its own sake, and something fresh expected from each newcomer, as was natural at a time when science was in the making, and consequently depended to no small degree on the personal influence of the teacher. Nor was it always the case that a lecturer on classical authors really belonged to the university of the town where he taught. Communication was so easy, and the supply of suitable accommodation, in monasteries and elsewhere, was so abundant, that a private appointment was often practicable. In the first decades of the fifteenth century, when the University of Florence was at its greatest brilliance, when the courtiers of Eugenius IV, and perhaps even of Martin V thronged the lecture-room, when Carlo Aretino and Filelfo were competing for the largest audience, there existed, not only an almost complete university among the Augustinians of Santo Spirito, not only an association of scholars among the Camaldolesi of the Angeli, but individuals of mark, either singly or in common, arranged to provide philosophical and philological teaching for themselves and others. Linguistic and antiquarian studies in Rome had next to no connection with the university (Sapienza), and depended almost exclusively either on the favour of individual popes and prelates, or on the appointments made in the Papal chancery. It was not till Leo X (1513) that the great reorganization of the Sapienza took place, which now had eighty-eight lecturers, among whom there were the most able men of Italy, reading and interpreting the class;cs. But this new brilliancy was of short duration. We have already spoken briefly of the Greek professorships in Italy.
