Rainalducci was born at Corvaro, an ancient stronghold near Rieti in Lazio. He joined the Franciscan order after separating from his wife in 1310, and became famous as a preacher.[2]
After spending four months in Rome, he withdrew with Louis IV to Viterbo,[2] but in December 1328 the papal legateCardinal Orsini began a campaign against Viterbo and Corneto.[3] Nicholas moved on to Grosseto and then to Pisa, where he was guarded by the imperial vicar. On 19 February 1329, Nicholas V presided at a ceremony in the Duomo of Pisa, at which a straw puppet representing Pope John XXII and dressed in pontifical robes was formally condemned, degraded, and handed over to the secular arm (to be "executed").
Nicholas V was excommunicated by Pope John XXII in April 1329, and sought refuge with Count Boniface of Donoratico near Piombino. Having obtained assurance of pardon, he presented a confession of his sins first to the archbishop of Pisa, and then at Avignon on 25 August 1330, to John XXII, who absolved him.[2]
He remained in honourable imprisonment in the papal palace, Avignon until his death in October 1333.[2] Despite this reconciliation, memories of him were highly negative in the later 1330s. In a monumental fresco by Buonamico Buffalmacco in the Camposanto Monumentale di Pisa, Nicholas V is depicted in Hell being dismembered and eaten by demons. The inscription describes him as a "friend of Muhammad", who is shown being tortured at his feet.[4]
