Of the chairs which have been mentioned, that of rhetoric was especially sought by the humanist; yet it depended only on his familiarity with the matter of ancient learning whether or no be could aspire to those of law, medicine, philosophy, or astronomy. The inward conditions of the science of the day were as variable as the outward conditions of the teacher. Certain jurists and physicians received by far the largest salaries of all, the former chiefly as consulting lawyers for the suits and claims of the State which employed them. In Padua a lawyer of the fifteenth century received a salary of 1,000 ducats, and it was proposed to appoint a celebrated physician with a yearly payment of 2,000 ducats, and the right of private practice, the same man having previously received 700 gold florins at Pisa. When the jurist Bartolommeo Socini, professor at Pisa, accepted a Venetian appointment at Padua, and was on the point of starting on his journey, he was arrested by the Florentine government and only released on payment of bail to the amount of 18,000 gold florins. The high estimation in which these branches of science were held makes it intelligible why distinguished philologists turned their attention to law and medicine, while on the other hand specialists were more and more compelled to acquire something of a wide literary culture. We shall presently have occasion to speak of the work of the humanists in other departments of practical life.
