Education
From Berwick he seems to have removed to the Franciscan schools at Oxford, at which university he became a Doctor of Theology, and is enumerated as the twenty-second reader of divinity belonging to that order in the early years of the fourteenth century.
Career
Barwick took his name from Berwick, where he appears to have been born or brought up. Leland also calls him the contemporary of William of Ockham, of whose doctrines, he adds, Barwick was a strenuous adherent. Bale states that he flourished about 1340.
And he appears to have read divinity lectures at Oxford about the beginning of the fourteenth century.
He was buried at Stamford.
