Three schools were especially famous in Paris: the "palatine or palace school", the "school of Notre-Dame", and that of Sainte-Geneviève Abbey. The decline of royalty brought about the decline of the first. The other two were ancient but did not have much visibility in the early centuries. The glory of the palatine school doubtless eclipsed theirs, until it completely gave way to them. These two centres were much frequented and many of their masters were esteemed for their learning. The first renowned professor at the school of Ste-Geneviève was Hubold, who lived in the tenth century. Not content with the courses at Liège, he continued his studies at Paris, entered or allied himself with the chapter of Ste-Geneviève, and attracted many pupils via his teaching. Distinguished professors from the school of Notre-Dame in the eleventh century include Lambert, disciple of Fulbert of Chartres; Drogo of Paris; Manegold of Germany; and Anselm of Laon. These two schools attracted scholars from every country and produced many illustrious men, among whom were: St. Stanislaus of Szczepanów, Bishop of Kraków; Gebbard, Archbishop of Salzburg; St. Stephen, third Abbot of Cîteaux; Robert d'Arbrissel, founder of the Abbey of Fontevrault etc. Three other men who added prestige to the schools of Notre-Dame and Ste-Geneviève were William of Champeaux, Abélard, and Peter Lombard.
