Modern scholarship suggests that the principium in aula was one part of a series of required steps in a master’s inception. There were disputed questions at or around the hour of vespers the day before the principium and others on the day of the official inception before the assembled masters, four in all. Although the possibility exists that what I have been calling resumptio addresses were the inception addresses given when a young baccalarius incepted as a biblicus, for the present, we will continue to accept the thesis that, in the thirteenth century, the principium in aula and the resumptio were two parts of a multistage ceremony. We have special reason to believe that Thomas’s second “commendation of Sacred Scripture” entitled Hic est liber came from his inception as a master, since he never incepted as a biblicus at Paris. As both Fr. Weiheipl and Fr. Torrell indicate, it is likely that Thomas delivered Hic est liber – an address that contained a continuation of his praise of Sacred Scripture and a divisio textus or partitio of all the books of the Bible – on the first day of classes after his inception.
