By the XIII century over thirty thousand students thronged the colleges in Paris. Aquinas taught in the Dominicans' branch of the university, in which same convent, called the Jacobins, lived the reader of Louis IX, Vincent de Beauvais, whose four _Mirrors_ were depicted in the imagery of the great cathedrals. No age was ever more enamored of encyclopædias. To overclassify was a characteristic of the times which even the great Aquinas could not escape. They say that over five hundred monks, under the guidance of the Dominican cardinal, Hugues de Saint-Cher, were busy in the rue St. Jacques preparing the first concordance of Scriptures. The entire Bible was translated into French in the XIII century. In the Franciscans' branch of the University St. Bonaventure taught. The king's chaplain, Robert de Sorbon, founded a house where poor students could live in common. Canterbury's archbishop, St. Edmund Rich, was a pupil in Paris, then a teacher. Roger Bacon, first to grasp the importance of experimental science, studied there, and so did Robert Grosseteste, builder of Lincoln Cathedral, whom Bacon said excelled all other masters in his range of useful knowledge.
The smelting pot of modern society those fecund formative years of the XII and XIII centuries have been called. A life-time's study it would be to draw adequately the picture of the one city of Paris then, when Philippe-Auguste and his grandson, St. Louis, were busy raising their Louvre and their Cité palaces, their Notre Dame, and their Sainte-Chapelle, busy cleaning the city streets and the city laws; when one scholarly bishop succeeded another as slowly rose the capital's cathedral, when lovely Latin hymns poured from St. Victor's abbey, while in the street the students sang the new lays of trouvère and troubadour, telling of "love that is a thing so high," of Roland and the _gestes_ of paladins, of the Celtic heroes, Tristan, Lancelot, and Percival; when all the newly awakened intellectual and art life was astir welding old blood and new, making Frenchmen, at last, of Celt and Latin and Frank, making a kind of commonwealth of the nations that met in universities whose common speech still was Latin.[80]
That there were black shadows in the picture, none deny. There were pillages and massacres. It was an agitated day full of tumults and heresies and terrible reprisals. One has only to read the censures of St. Bernard and of Innocent III to learn of the cupidity and the lust. Joinville has told of a sink of corruption lying within a stone's throw of the saint-king's crusading camp. But, above all the lawlessness, the men of those ages of faith aspired. Their acts might fall short; their principles remained sound. "No easy-going doctrines, then, to legitimize vice," says Ozanam. Man knew how to beat his breast in humble repentance. He lifted his eyes toward an ideal so far above himself that it was given his human weakness to build cathedrals such as Notre Dame of the capital. Not so does he build when as superman he sits on a self-raised altar.
