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 about three hours before dawn, a phenomenon which the narrator makes no attempt to explain.[34] Having crossed to survey the Venetian possessions at Zara, the Duke returned home in 1536, on board two galleys of the Republic. The rest of that year was chiefly spent by him at his post in Lombardy, protecting the Venetian mainland during the passage of some imperial levies; but his charge was no longer an important one, as the long contests for Milan had been finally set at rest in the autumn of 1535, by the death of Duke Francesco Sforza, after naming Charles V. heir of his state.

Apulia and the Venetian possessions in the Levant being menaced in the following year by Sultan Solyman, a general confederation was effected for the defence of Italy and its dependencies, at the head of which were the Pope and the Emperor. The Duke of Urbino as captain-general undertook to raise five thousand men for this armament, but, the danger suddenly passing away, distracted counsels prevailed among the allies. Finally, on the 31st of January, 1538, a new league was patched up, to carry into effect a suggestion of Francesco Maria, by diverting the war into the Infidel's territory. Considering, however, his impending difficulties with Paul III., the Duke obtained a joint guarantee of the contracting powers for maintenance in his state, in confirmation of papal brieves to the same effect dated in the preceding November. About the same time his services to the Republic were acknowledged by the present of a palace in the street of Sta. Fosca, valued at 16,000 ducats.

The views of the allies and their captain-general for this enterprise were vast, comprehending the siege of Constantinople and an invasion of Egypt: and the latter was indefatigable in his endeavours to put the armament upon a footing equal to such extensive designs, both as to its numbers and material. The enterprise was invested with the sacred character of a religious war; but whilst Francesco Maria concentrated upon it the energies of a mind in its prime, and the exertions of a frame renovated by new specifics against his hereditary enemy the gout, the hand of death was upon him. Returned to Venice from a comprehensive survey of her defences in Dalmatia and Istria, he was attacked by sudden illness on the 20th of September. Foreseeing its fatal termination, he had himself taken by sea to Pesaro, which he reached on the 8th of October. Next day he showed himself on horseback to his people, but feeling unequal to the exertion he took to bed, and gradually lost strength. On Monday, the 21st, a fit deprived him of speech, yet he continued sensible until near daybreak of the 22nd, when he expired in religious penitence, after receiving the sacraments.

All authorities agree in attributing his death to poison, but neither Leoni nor Baldi hint at the person whose "envy" dictated that base vengeance.[*35] Giovio speaks positively as to detection having followed upon a searching inquiry, and points at those interested in the Camerino question as authors of the crime. Sardi and Tondini charge it upon Luigi Gonzaga, Count of Sabionetta, surnamed Rodomonte, the nephew of Francesco da Bozzolo, a condottiere who commanded Bourbon's cavalry at the assault of Rome, and who facilitated Clement's flight some months thereafter. This assertion, which is adopted by various writers, receives some confirmation from a story in the gossiping MS. we have already quoted, that Gonzaga, having accused Gian Giacomo Leonardi, a doctor of laws at Pesaro, of instigating the murder, was challenged by the latter, who thereby gained the favour of Duke Guidobaldo II., and with it the countship of Monte l'Abbate, near Pesaro.[36] On the other hand, this Rodomonte is stated in Les Genealogies des Maisons Souveraines to have died in 1528.

Whoever may have been author of the foul deed, it is agreed that the perpetrator was the Duke's Mantuan barber, who is generally said to have dropped a poisoned lotion into his ear. Baldi only mentions that he did it "in a new way," and gives no account of the medical examination of the body which, he asserts, took place. In an old chronicle of Sinigaglia, Guidobaldo is stated to have had the barber torn to pieces with pincers, and quartered in the streets of Pesaro.[37]

After a cast in plaster had been taken from his features, the body was dressed in a quilted doublet and hose of black satin, under his inlaid armour, over which was the ducal tunic, and, above all, the mantle of crimson satin embroidered in gold, which he had worn as Prefect at the coronation of Charles V. Next evening it was borne, with torches, by the principal courtiers, to the great hall, and there placed upon an elevated catafalque of black and gold, on which were arranged his ducal helmet, three magnificent head pieces, and as many silver batons of command; five standards which he had captured being set round with other trophies. It was watched all night, and lay in state till the following evening, when it was coffined in the dress just described. The same night it was taken on a litter to Urbino by torchlight, escorted by a vast following on horseback and on foot, under soaking rain. At the confines of the respective territories it was delivered over to the authorities and clergy of that city, preceded by mutes and mourners of various grades; among whom was led the Duke's favourite jennet, covered with black velvet, his ducal mail and morion being carried by a page in deep weeds. Reaching the city at sunrise, the procession was joined by the chief magistrates, nobility, clergy, and citizens, and so arrived, through tearful crowds, at the church of Sta. Chiara, again to lie in state until evening, when it was stripped of its armour, and there committed to the dust at the left horn of the altar. It was subsequently deposited, by his grandson Francesco Maria II., in a tomb raised over the spot by Bartolomeo Ammanati, from the design of Girolamo Genga, which was eventually removed as inconveniently cumbering the church. The following epitaph, written by desire of the widowed Duchess, and ascribed to the pen of Bembo, is panelled into the wall:—

"To Duke Francesco Maria, endowed with the most comprehensive capacity for war and peace. His hereditary states, thrice lost by violence, he thrice by valour regained, and ruled them, when reconquered, with moderation; he commanded the Ecclesiastical, the Florentine, and the Venetian forces; finally, he was chosen general-in-chief for the Turkish war, but was cut off ere it opened. Leonora, his most devoted wife, placed this to her most meritorious lord, and to herself."

One more ceremonial was wanting to complete the measure of respectful duty to the deceased sovereign. On the 13th [or 22nd] of November, his obsequies were celebrated in the cathedral of Urbino. The church decorations, the catafalque, the vast concourse of clergy, of deputations, and of people of all classes, were such as the mournful solemnity required, and the sincere grief of his subjects dictated. The function was conducted by Federigo Fregoso, Archbishop of Salerno, whom we have formerly known at the court of Duke Guidobaldo I., and the funeral oration was spoken by Maestro Benedetto Milesio. Another, by Lorenzo Contarini, was pronounced at Venice, where the Signory ordered a celebration of his obsequies with unwonted splendour, besides voting him an equestrian statue in bronze. This was never executed, but another statue of him, made by Bandini for his grandson, the last Duke of Urbino, was presented to the Republic under touching circumstances, which we shall detail in the [fifty-fourth chapter] of this work.
