The school of law was founded by Placentinus, a doctor from Bologna University, who came to Montpellier in 1160, taught there during two different periods, and died there in 1192. The school of medicine was founded perhaps by a graduate of the Muslim Spain medical schools; it is certain that, as early as 1137, there were excellent physicians at Montpellier. The statutes given in 1220 by Cardinal Conrad, legate of Honorius III, which were completed in 1240 by Pierre de Conques, placed this school under the direction of the Bishop of Maguelonne. Pope Nicholas IV issued a Bull in 1289, combining all the schools into a university, which was placed under the direction of the bishop, but which in fact enjoyed a large measure of autonomy. Theology was at first taught in the convents, in which St. Anthony of Padua, Raymond Lullus, and the Dominican Bernard de la Treille lectured. Two letters of King John prove that a faculty of theology existed at Montpellier independently of the convents, in January 1350. By a Bull of 17 December 1421, Martin V granted canonical institution to this faculty and united it closely with the faculty of law. In the 16th century the faculty of theology disappeared for a time, when Calvinism, in the reign of Henry II of France, held complete possession of the city. It resumed its functions after Louis XIII had reestablished the royal power at Montpellier in 1622; but the rivalries of Dominicans and Jesuits interfered seriously with the prosperity of the faculty, which disappeared at the Revolution. The faculty numbered among its illustrious pupils of law Petrarch, who spent four years at Montpellier, and among its lecturers Guillaume de Nogaret, chancellor to Philip the Fair, Guillaume de Grimoard, afterwards pope under the name of Urban V, and Pedro de Luna, antipope as Benedict XIII. But after the 15th century this faculty fell into decay, as did also the faculty of arts, although for a time, under Henry IV of France, the latter faculty had among its lecturers Casaubon. The Montpellier school of medicine owed its success to the ruling of the Guilhems, lords of the town, by which any licensed physician might lecture there; there was no fixed limit to the number of teachers, lectures were multiplied, and there was a great wealth of teaching. Rabelais took his medical degrees at Montpellier.
