John Canon is said to have flourished c. 1320, and to have attended the lectures of Duns Scotus at Oxford and Paris[1441]. Wood, referring to the regestrum Oriell, says that his
‘philosophicall treatises were soe much esteemed among the students of this University that they were read to them by their tutors and by logick lecturers in each society[1442].’

‘Philippus a Castellione Aretino’ (Castello near Arezzo) in the Tuscan province, is described by Wadding as, ‘in theologia magister insignis apud Oxonienses.’ He flourished 1316, and wrote treatises on the poverty of Christ[1445].
William of Ockham, ‘Auctor nominalium,’ ‘Doctor singularis,’ ‘Doctor invincibilis[1446],’ was born probably towards the end of the thirteenth century. Whether he was a pupil of Duns Scotus is doubtful. He studied at Oxford in the early years of the fourteenth century, and became B.D. there[1447]. After this he was called to Paris, where he incepted as D.D. Here he became acquainted with Marsiglio of Padua, over whom, according to Pope Clement VI, he exercised a powerful influence[1448]. It is probable that he was present at the famous Chapter of Perugia (1322), though he was not (as is usually asserted) Provincial of England[1449]. From the first he took a prominent part in the struggle against the Pope[1450]. He was imprisoned at Avignon about the end of 1327, and a process was instituted against him in the Curia
‘because of many erroneous and heretical opinions which he had written[1451].’
