  Although Tempier’s action of March 7, 1277 is best known in the historiography of philosophy, mention should also be made of two additional doctrinal investigations of 1277 that are attributed to Bishop Tempier. The first one concerned the theologian Giles of Rome, and was concluded before March 28, 1277 with the censure of fifty-one propositions taken from Giles’s commentary on the Sentences. The second doctrinal inquiry was aimed against Thomas Aquinas. It was begun after Giles’s censure, but still before March 28, 1277. According to Robert Wielockx, the inquiry against Thomas Aquinas was never completed. Basing his conclusions on evidence provided in a letter by John Pecham, Wielockx claimed that during the vacancy of the Apostolic See, sometime between May 20 and November 25, 1277, Tempier received orders from the curia to stop his investigation.
