Matters were brought to a crisis by the offer of the crown of Sicily to Henry for his younger son, Edmund, first made by Innocent IV., and confirmed by his successor, Alexander IV., in the hope of using the wealth of England to crush Conrad, and afterwards Manfred, the sons of Frederic II. Henry greedily swallowed the bait, and incurred an enormous debt to the Pope for the war in Apulia. By the advice of Peter, the Provencal bishop of Hereford, he tried to satisfy the Pope by the shameful trick of attaching the seals of the bishops, without their knowledge, to blank bonds, to be filled up as the Pope chose. Alexander IV. treated the English Church as insolently as his predecessor. Soon after the appointment of an Englishman to the deanery of York in 1256, an Italian cardinal appeared in the church, and was installed as dean by his companions; he had been "provided" by the Pope. The archbishop, Sewal de Bovil, had been a pupil of Edmund of Canterbury, by that time canonized, and was a friend of the famous Oxford Franciscan, Adam Marsh. He successfully resisted the intrusion. His courage brought excommunication on him and an interdict on his church, and he died broken-hearted, after sending a letter to the Pope bidding him remember that the Lord's charge to Peter was to "feed His sheep, not shear them or devour them." In 1256, Alexander's envoy, Rustand, pressed the bishops for a tenth for three years for the Sicilian scheme. Fulk, bishop of London, declared that he would sooner lose his head; and Walter of Cantelupe, bishop of Worcester, that he would sooner be hanged. Henry, as his wont was, abused Fulk, and threatened that the Pope should deprive him. "Let them take away my mitre, I shall still keep my helmet," was the bishop's answer. The clergy remonstrated against the envoy's proposal in their diocesan synods, and, thanks to the opposition offered by the lay barons, the Pope and the king were defeated. The reverence which Englishmen formerly had for the Roman Church had now disappeared, and bitter and contemptuous feelings had taken its place. The venality of the papal court and the wrongs of the Church were the favourite themes of the ballad-singer; and English monks loved to tell of visions which represented Innocent as dying struck by the spear of the glorified bishop of Lincoln, and of the sentence pronounced against him by the Eternal Judge on the accusation of the Church he had persecuted and degraded.
