Later career in Avignon, and death (1332 to 1343/4). Chatton is known to have been in Avignon on 17 January, 1333. He was summoned there in order to participate in hearings against Thomas Waleys, and eventually he served as an advisor to Pope Benedict XII. His career took an excellent upward turn in 1343 when he was appointed bishop of the Welsh See of Asaph, but this good fortune reversed itself when it turned out the position was not really vacant. That winter, earthly good fortune gave up on Chatton completely, and he died in Avignon, late in 1343 or perhaps early 1344.[5]
