The church which now is Montpellier's cathedral consists of a modern choir of the meridional type, without ambulatory or flying buttresses, and a nave built as an abbatial by Guillaume de Grimoard, the best of the Avignon popes, Urban V. The nave is a wide, unaisled hall, with small clearstory windows. Even when the Midi used diagonals, says M. Enlart, it remained faithful to Romanesque traditions. At the west façade is an ungainly canopy held up by two round turrets of solid stone, the sort of thing which is a builder's notion, not the design of an architect. Urban was disappointed when he found that his architect from Avignon had erected a big chapel rather than a church. When he came to Montpellier in 1367 the new edifice was almost finished. He was honored as never man was before by any city. The townspeople marched out to meet him, every guild and corporation in the ranks, the lawyers carrying the image of the newly canonized St. Yves of Brittany. When the pope's visit ended, half the population walked for miles with him into the country, and the town authorities escorted him all the way back to Avignon. Urban V had been educated in Montpellier and he loved its university, in which for years he had taught law in the school where Petrarch studied. He renewed the departments of law and art, put new life into the famed medical school (which to-day is housed in the former bishop's palace, fortified with propped machicolations), and founded a college for the free maintenance of a certain number of students. To this day Montpellier reveres him. All over Christendom this energetic Midi baron endowed institutions of learning, supported hundreds of students, and built monuments. He founded the universities of Prague, Cracow, and Vienna, re-established that of Orvieto, made a school of music at Toulouse, began the cathedral of Mende,[246] near his birthplace, and in Marseilles rebuilt St. Victor's, where he had been abbot,[247] and where remains his towering tomb. At Avignon he continued the making of its walls of defense, for it was a day when the lawless _Grandes Compagnies_ roved over France. Urban was too wise a man not to perceive that his continued residence at Avignon was a detriment to the papacy, and he made a valiant effort to return to Rome. There, too, he was no sooner established than he initiated works of art.[248] Broken by the disorders round him with which he had not strength to cope, he returned to his beloved southern France, where he died almost immediately, in 1370. His successor, Gregory XI, inspired by St. Catherine of Siena, who journeyed to Avignon in 1376, was to be the pontiff who ended what Italy, sick to death, called "the Babylonian captivity."
