Vicar of Winkfield, Berkshire (1314–1332), Guilelmus studied and taught at Oxford from 1314, leaving a number of pastoral treatises. He summed up his work in an elaborate Summa summarum (1319–22), which was intended to offer a solution to any question of pastoral or legal concern. Largely influenced by the Repertorium of Guilelmus Durantis and the penitential Summa of Johannes of Friburgensis, its scope of legal and theological references was nevertheless much wider. The work circulated in England throughout the later Middle Ages.
