The plan of studies expanded in the schools of Paris, as it did elsewhere. A Bolognese compendium of canon law called the "Decretum Gratiani" brought about a division of the theology department. Hitherto the discipline of the Church had not been separate from so-called theology; they were studied together under the same professor. But this vast collection necessitated a special course, which was undertaken first at Bologna, where Roman law was taught. In France, first Orléans and then Paris erected chairs of canon law. Before the end of the twelfth century, the Decretals of Gerard La Pucelle, Mathieu d'Angers, and Anselm (or Anselle) of Paris, were added to the Decretum Gratiani. However, civil law was not included at Paris. In the twelfth century, medicine began to be publicly taught at Paris: the first professor of medicine in Paris records is Hugo, "physicus excellens qui quadrivium docuit".
