The great North Italian Universities of Bologna, Padua, Pisa, and Pavia, were then at the height of their renown as centres of mathematics, law, and medicine. Harvey chose to attach himself to Padua, and many reasons probably influenced him in his choice. The University was specially renowned for its anatomical school, rendered famous by the labours of Vesalius, the first and greatest of modern anatomists, and by the work of his successor, Fabricius, born at Aquapendente in 1537. Caius had lectured on Greek in Padua, and some connection between his college at Cambridge and his old University may still have been maintained, though it was now nearly a quarter of a century since his death. The fame of Fabricius and his school was no doubt the chief reason which led Harvey to Padua, but there was an additional reason which led his friends to concur cheerfully in his resolve. Padua was the University town of Venice, and the tolerance which it enjoyed under the protection of the great commercial republic rendered it a much safer place of residence for a Protestant than any of the German Universities, or even than its fellows in Italy. The matriculation registers which have recently been published show how large a number of its medical and law students were drawn from England and the other Protestant countries of Europe, and the English and Scotch "nation" existed in Padua as late as 1738, when the days of mediæval cosmopolitanism were elsewhere rapidly passing away. The Universities of Europe have always been of two types, the one Magistral, like that of Paris, with which we are best acquainted, for Oxford and Cambridge are modelled on Paris, and the Masters of Arts form the ruling body; the other, the Student Universities, under the control of the undergraduates, of which Bologna was the mother. Hitherto Harvey had been a member of a Magistral University, now he became attached to a University of Students, for Padua was an offshoot of Bologna. Hitherto he had received a general education mainly directed by the Church, now he was to follow a special course of instruction mainly directed by the students themselves, for they had the power of electing their own teachers, and in these points lies the great difference between a University of Masters and a University of Students.
