Cantilupe died at Ferento, near Orvieto, in Italy, on 25 August 1282. He is buried in Hereford Cathedral. Part of the evidence used in his cause of canonization was the supposed raising from the dead of William Cragh, a Welsh rebel who was hanged in 1290, eight years after Cantilupe's death. A papal inquiry was convened in London on 20 April 1307 to determine whether or not Cantilupe had died excommunicate, since this would have precluded his being canonized. Forty-four witnesses were called and various letters produced, before the commissioners of the inquiry concluded that Cantilupe had been absolved in Rome before his death. It was difficult for his cause of death to be determined as much of his body had disintegrated.
