Brother Bonaventura of Bagnoreggio said of Brother Giles, that God had given him special graces, not only for himself, but for all those also who should recommend themselves to him with a devout intention in any spiritual need. He wrought many miracles, both in his lifetime and after his death, as appeareth by his legend, and he passed from this life on the Feast of St George, in the year 1252. He is buried at Perugia in the convent of the Friars Minor.
