Originally the main source of university authority was the body of active teachers (regents) acting with the concurrence of the chancellor who represented the bishop of Ely; their grouping in faculties was an obvious development, and probably took place early in the thirteenth century. Resident graduates who had ceased to teach (non-regents) were allowed a voice on matters of property, rights, and privileges. The establishment of monasteries and colleges with administrative officers tended to retain in residence graduates who were not lecturing; through them the house of non-regents grew in power, and finally in many questions obtained concurrent jurisdiction with that of the regents--the result was a very complex constitution. At first the University had no buildings of its own; the regent and non-regent houses met in St Benet's or St Mary's church, and lectures were given wherever accommodation could be obtained. After this digression I return to the position of the students in the early University. Numerous monasteries were established in Cambridge during the thirteenth century, and from this I infer that the number of members of the religious Orders studying in the University steadily increased during that century. Of monastic Houses in Cambridge previous to the foundation of the University I have already mentioned those of the Augustin Canons, founded in connection with St Giles' church, about 1092, and moved in 1112 to Barnwell where their priory became in time one of the largest conventual buildings in England, and of the Austin Brethren of Frost's or St John's Hospital, built about 1135 on ground now occupied by St John's College. Shortly after the organization of a studium in the town, five important Orders established Houses here. These were the Franciscan or Grey Friars, who, from their first home situated near the present Divinity Schools and used from 1224 to 1294, removed in 1294 to a site now occupied by Sidney Sussex College, where their church was one of the conspicuous architectural features of medieval Cambridge; the Dominican or Black Friars, who built in 1274 on ground now occupied by Emmanuel College; the Carmelite or White Friars, who, having previously lived in houses at Chesterton and Newnham, removed in 1290 to a site now occupied by Queens' and King's Colleges; the Augustine Friars, who built, about 1290, a home on or near ground now occupied by the university examination halls and lecture rooms, in the basement of which some fragments of the old friary may be found; and the Sempringham or White Canons, who about 1290 obtained possession of St Edmund's Priory which had been built before 1278 near the Trumpington Gate. The Houses of the Bethlehem Friars, opened in 1257, of the Friars of the Sack, opened in 1258, and of the Friars of St Mary, opened in 1273, were suppressed in 1307, and probably were never important foundations. I believe that the presence
