 Scholars have proposed different hypotheses regarding Grosseteste’s life between about 1200 and 1230.  According to Daniel Callus (Callus 1945, 1955, with Crombie 1953 and McEvoy 1982, 2000 in substantial agreement), from about 1200 Grosseteste probably taught the arts at Oxford, only to leave Oxford in 1209 to study theology in France when the Oxford schools closed after some clerics were hanged by Oxford’s mayor and officers. The resolution of the resulting town-and-gown dispute was delayed by the papal interdict of England but finally achieved in 1214, when the papal legate sent to England to negotiate a settlement between the king and pope visited Oxford.  The legate’s resolution, known as the Legatine Award, placed the Oxford masters under the jurisdiction of the Bishop of Lincoln, who was to appoint as his representative a chancellor of the university. Remarks by Hugh Sutton, Grosseteste’s successor as Bishop of Lincoln, indicate that Grosseteste had at one time occupied the position of chancellor at Oxford but had been allowed only to use the title “master of the schools” and not “chancellor.” According to Callus, Grosseteste probably returned from France in 1214 to become, in function if not title, Oxford’s first chancellor, and lectured on theology in Oxford’s secular schools from this year until 1229/30.
