Petrarch then lived, and though he was a citizen of Avignon, he prayed night and morning for the rebuilding of the Roman pontificate. Listening to him, Urban went to Italy to recover if possible the patrimony of Saint Peter, or, if you insist, that of the Countess Matilda. He was confronted by that chronic enemy of the papacy, the Visconti. At that time the head of that house was one Bernabo who was if anything a little less bland in his way than his predecessors. After many high words, Urban lost his temper and let fly at Bernabo a major excommunication cursing him in eating and drinking and sleeping and in all the functions of life, and redoubling the anathema upon him wherever he might fetch up in the life to come. Bernabo seized the legate who brought the bull, and made him eat it--parchment, ribbon, leaden seal and all. What sauce was allowed him with this strange victual, and how he felt after supper, have not been handed down to us. Not content with that, the impious ruffian sent Urban word that it was he, Bernabo, who was pope in Italy, and emperor to boot; and that the Almighty himself dared do nothing there without his consent. On Urban’s return to Avignon, a fresh humiliation awaited him. Peter-the-cruel king of Castile had an illegitimate brother, Henry of Trastamara who undertook to dethrone him. Henry obtained the aid of the famous French knight, Bertrand du Guesclin, and also of a band of mercenary soldiers called Free Companions who were not always distinguishable from free-booters. In their march toward Spain, they encamped one night on the bank of the Rhone opposite Avignon, and sent to the Holy Father praying that he would pardon their sins, bless their enterprise and give them some money. Urban granted them absolution and benediction; but he told them he had no money for them, and bid them be gone. They demanded forty thousand crowns in gold as the price of their departure. Urban launched at them a thunder-bolt as pregnant with disaster as the one he had discharged at Bernabo. Du Guesclin himself then sought an interview with his Holiness, and told him that he had no control over those marauders except on the field of battle, and that they were threatening to sack the papal palace. Urban, thoroughly frightened, recalled his curses and renewed his benedictions; but as his conscience would not allow him to take money out of the sacred treasury to give to such miscreants, he laid a tax on the citizens of Avignon, and they had to pay the sum demanded. Gregory XI., nephew of Clement VI. was the next pope, and the last of the Captivity. He secured Avignon from being again put to ransom by the Free Companions by taking into his service a troop of them commanded by an Englishman named Sir John Hawkwood.
