It is commonly believed that Abelard's school on Mont St. Genevieve was the origin of the Latin Quarter in Paris, but the migration to the south had probably begun before Abelard came, and was rather due to the overcrowding of the episcopal schools. Teachers and scholars began to swarm to the new quarter over the bridge where quiet, purer air and better accommodation were found. Ordinances of Bishop Gilbert, 1116, and Stephen, 1124, transcribed by Felibien, make this clear. So disturbed were the canons by the numbers of students in the cloister, that _externes_ were to be no longer admitted, nor other schools allowed on the north side where the canons lodged. The growing importance of the new schools, which tended to the advantage of the abbey of St. Genevieve, soon alarmed the bishops, and the theologians were ordered to lecture only between the two bridges (the Petit and Grand Ponts.) But it was Abelard's brilliant career that attracted like a lodestar the youth of Europe to Paris, and made that city the "oven where the intellectual bread of the world was baked." Providence, it was said, had given Empire to Germany, Priestcraft to Italy, Learning to France. What a constellation of great names glows in the spiritual firmament of mediaeval Paris: William of Champeaux, Peter Lombard, Maurice de Sully, Pierre de Chartreux, Abelard, Gilbert[66] l'Universel, Adrian IV., St. Thomas of Canterbury, and his biographer John of Salisbury. Small wonder that the youth of the twelfth century sought the springs of learning at Paris! [Footnote 66: Afterwards bishop of London.] [Illustration: NOTRE DAME AND PETIT PONT.]
