It is sometimes thought that the word university applied to these institutions after the aggregation of other faculties, was due to the fact that there was a universality of studies, that all branches of knowledge might be followed in them. The word university, however, was not originally applied to the school itself, which, if it had all the faculties of the modern university, was, in the Thirteenth Century, called a _studium generale_. The Latin word universitas had quite a different {21} usage at that time. Whenever letters were formally addressed to the combined faculties of a _studium generale_ by reigning sovereigns, or by the Pope, or by other high ecclesiastical authorities, they always began with the designation, Universitas Vestra, implying that the greeting was to all of the faculty, universally and without exception. Gradually, because of this word constantly occurring at the beginning of letters to the faculty, the term universitas came to be applied to the institution. [Footnote 1] [Footnote 1: Certain other terms that occur in these letters of greeting to university officials have a more than passing interest. The rector of the university, for instance, was always formally addressed as Amplitudo Vestra, that is, Your Ampleness. Considering the fact that not a few of the rectors of the old time universities, all of whom were necessarily ecclesiastics, must have had the ampleness of girth so characteristic of their order under certain circumstances, there is an appropriateness about this formal designation which perhaps appeals more to the risibilities of the modern mind than to those of medieval time.] While the universities, as is typically exemplified by the histories of Bologna and Paris, and even to a noteworthy degree of Oxford, grew up around the cathedrals, they cannot be considered in any sense the deliberate creation, much less the formal invention, of any particular set of men. The idea of a university was not born into the world in full panoply as Minerva from the brain of Jove. No one set about consciously organizing for the establishment of complete institutions of learning. Like everything destined to mean much in the world the universities were a natural growth from the favoring soil in which living seeds were planted. They sprang from the wonderful inquiring spirit of the time and the marvelous desire for knowledge and for the higher intellectual life that came over the people of Europe during the Thirteenth Century. The school at Paris became famous, and attracted pupils during the Twelfth Century, because of the new-born interest in scholastic philosophy. After the pupils had gathered in large numbers their enthusiasm led to the establishment of further courses of study. The same thing was true at Bologna, where the study of Law first attracted a crowd of earnest students, and then the demand for broader education led to the establishment of other faculties. {22}
