GUALTIERO of CHATTON. – English Franciscan theologian, born in Chatton (Norwich) in the second half of the 13th century, died at Avignon probably in 1343.
From the Franciscan school of Oxford, of which he was the 53rd regent, he moved in 1333 to Avignon, where his learning earned him the favour of John XXII, Benedict XII and Clement VI, who appointed him papal penitentiary and entrusted him with the bishopric of St-Aspah; though GUALTIERO did not take possession of it, since the bishop who held it had not died, contrary to the rumour that had spread. He also collaborated on the bull *Redemptor noster* of 28 November 1336, by which the new Franciscan Constitutions were promulgated.
Two works remain from him: a *Commentarius Sententiarum*, more extensive in the first part and more summary in the other three, which are therefore considered rather a reportatio by some pupil, and *De paupertate evangelica*.
It is difficult to say with certainty to which philosophical and theological school he belonged; scholars’ opinions vary; yet GUALTIERO clearly emerges as a strong and subtle critic of Ockham and his school.
