In 1265 and 1266 Clement IV. is found issuing instructions as to the duties and appointment of inquisitors as vigorously as though there were no impediments to their functions. It seemed only a question of time, however, when the districts yet open should be closed to them.[257] There have been few revolutions more pregnant with results than that which occurred when the popes, renouncing the hope of acquiring for themselves the kingdom of Sicily, and vainly tempting Edmond, son of Henry III. of England, succeeded in arousing the ambition of Charles of Anjou, and caused a crusade to be preached everywhere in his behalf. The papacy fully recognized the supreme importance of the issue, and staked everything upon it. The treasures of salvation were poured forth with unstinted hand, and plenary indulgences were given to all who would contribute a fourth of their income or a tenth of their property. The temporal treasury of the Church was drawn upon with equal liberality. Three years’ tithe of all ecclesiastical revenues in France and Flanders were granted to Charles, and when all this proved insufficient, Clement IV. sacrificed the property of the Roman churches without hesitation. An effort to raise one hundred thousand livres by pledging it brought in only thirty thousand, and then he pawned for fifty thousand more the plate and jewels of the Holy See. He could truly answer Charles’s increasing demands for money to support his naked and starving crusaders by declaring that he had done all he could, and that he was completely exhausted--he had no mountains and rivers of gold, and could not turn earth and stones into coin. So utter was his penury that the cardinals were reduced to living at the expense of the monasteries; and when the Abbot of Casa Dei complained of the number quartered on him, he was told that he would be relieved of the Cardinal of Ostia, but that he must support the rest. More permanent relief, however, was found at the expense of the foreigner by assigning to them revenues on churches abroad on the liberal scale of three hundred marks a year apiece.[258]
