A friar of Appignano in the Marches region of Italy, he probably studied at Paris ca. 1310, returning to lecture on the Sentences in Paris in 1319-20. Teaching at Avignon (1324-28), he supported the Minister General, Michael of Cesena, in his dispute with John XXII on Franciscan poverty, he went to Pisa, and to Munich (1330); tried by the Inquisition, he recanted and was reconciled in 1343. We have his Improbatio against John XXII, a commentary on the Sentences and on the Metaphysics of Aristotle.
