Francesco Maria now interposed all his influence, backed by the imperial and the Venetian ambassadors, to induce Paul to a recognition of Giulia as heiress under the investiture given to her father, with remainder apparently to heirs general. Having vainly exhausted the expedients of diplomacy in this cause, he protested that the blame should not rest upon him of hostilities rendered necessary in his son's defence, and, sending provisions to Camerino, he marched at the head of ten thousand men to his support. At Sassoferrata he was met by a deputation of the citizens, laden with presents, who declared that though their walls were the Pope's, their hearts and substance were at his disposal. At Matelica he found his son and the ladies, before whom he passed his army in review, and marched home again without once encountering the papal troops under Gian Battista Savello. In fact, it was a war of the pen rather than the sword, for at every step he renewed notarial protests of duty and obedience to the Church, and regularly paid the excise, as well as the price of all the stores which he took up for the use of the Varana party. Apprehending that, if too far provoked, he would be supported by the Venetian arms and by the Emperor, the Pontiff now suspended martial measures, and pressed the point of law on the Roman courts. Thus relieved from immediate anxiety in this matter, the Duke of Urbino resolved to pay a visit of compliment to Charles V. at Naples. After reaching the Adriatic frontier of that kingdom, he dismissed the strong escort which had guarded him through the ecclesiastical state, and proceeded with a small suite. The Emperor received him with much courtesy, and sought his counsel in the invasion of Provence, which he was preparing. Francesco Maria would gladly have referred the Camerino affair to his arbitration, but this being rejected by the Nuncio, he obtained simply the imperial mediation, which proved unavailing. He on this occasion presented Charles with two swords of tried temper, and a finger-ring containing a repeating watch, the latter made at Pesaro. In returning he took the route by Benevento to the Adriatic, and halting for the night at the convent of Sta. Maria degl'Eremiti, near Troia, he allowed some of his attendants to examine into a curious tradition which then obtained general credit. It was said that Diomed arriving here with a company of attendants, he and most of them died within a few days, and were duly interred; but that their souls were transmigrated into a species of bird elsewhere unknown, which ever since had haunted the marshy grounds. These were seen but rarely of an evening, and towards morning uttered sounds like human lamentations. They flew on the approach of any one not of Greek birth, but allowed persons of that nation to visit their haunts familiarly. Three of the Duke's suite having volunteered to watch, they all heard mournful voices
