The three schools: Notre-Dame, Sainte-Geneviève, and Saint-Victor, may be regarded as the triple cradle of the "Universitas scholarium", which included masters and students; hence the name "University". Henry Denifle and some others hold that this honour is exclusive to the school of Notre-Dame (Chartularium Universitatis Parisiensis), but the reasons do not seem convincing. He excludes Saint-Victor because, at the request of the abbot and the religious of Saint-Victor, Gregory IX in 1237 authorized them to resume the interrupted teaching of theology. But the university was largely founded about 1208, as is shown by a Bull of Innocent III. Consequently, the schools of Saint-Victor might well have contributed to its formation. Secondly, Denifle excludes the schools of Ste-Geneviève because there had been no interruption in the teaching of the liberal arts. This is debatable and through the period, theology was taught. The chancellor of Ste-Geneviève continued to give degrees in arts, something he would have ceased if his abbey had no part in the university organization.
