In 1296 he was charged by Boniface VIII

Guillaume composed, about 1300, the Summa Libelli Electionum, avery peculiar work, which contains some interesting details on the Church of Toulouse. Some time afterwards it was revised by John Andreae, and dedicated to Berenger (Cologne, 1573). Guillame died at Avignon in November 1321. See Hoefer, Nouv. Biog. Generale, s.v.
