While Lucrezia was on her way to Ferrara to meet her fourth husband, Alexander and the Duke of Valentinois resolved to make a progress in the region of their last conquest, the duchy of Piombino.  The apparent object of this journey was that the new subjects might take their oath to Caesar, and the real object was to form an arsenal in Jacopo d’Appiano’s capital within reach of Tuscany, a plan which neither the pope nor his son had ever seriously abandoned.  The two accordingly started from the port of Corneto with six ships, accompanied by a great number of cardinals and prelates, and arrived the same evening at Piombina.  The pontifical court made a stay there of several days, partly with a view of making the duke known to the inhabitants, and also in order to be present at certain ecclesiastical functions, of which the most important was a service held on the third Sunday in Lent, in which the Cardinal of Cosenza sang a mass and the pope officiated in state with the duke and the cardinals.  After these solemn functions the customary pleasures followed, and the pope summoned the prettiest girls of the country and ordered them to dance their national dances before him.

Following on these dances came feasts of unheard of magnificence, during which the pope in the sight of all men completely ignored Lent and did not fast.  The abject of all these fetes was to scatter abroad a great deal of money, and so to make the Duke of Valentinois popular, while poor Jacopo d’Appiano was forgotten.

When they left Piombino, the pope and his son visited the island of Elba, where they only stayed long enough to visit the old fortifications and issue orders for the building of new ones.

Then the illustrious travellers embarked on their return journey to Rome; but scarcely had they put out to sea when the weather became adverse, and the pope not wishing to put in at Porto Ferrajo, they remained five days on board, though they had only two days’ provisions.  During the last three days the pope lived on fried fish that were caught under great difficulties because of the heavy weather.  At last they arrived in sight of Corneto, and there the duke, who was not on the same vessel as the pope, seeing that his ship could not get in, had a boat put out, and so was taken ashore.  The pope was obliged to continue on his way towards Pontercole, where at last he arrived, after encountering so violent a tempest that all who were with him were utterly subdued either by sickness or by the terror of death.  The pope alone did not show one instant’s fear, but remained on the bridge during the storm, sitting on his arm-chair, invoking the name of Jesus and making the sign of the cross.  At last his ship entered the roads of Pontercole, where he landed, and after sending to Corneto to fetch horses, he rejoined the duke, who was there awaiting him.  They then returned by slow stages, by way of Civita Vecchia and Palo, and reached Rome after an absence of a month.  Almost at the same time d’Albret arrived in quest of his cardinal’s hat.  He was accompanied by two princes of the house of Navarre, who were received with not only those honours which beseemed their rank, but also as brothers-in-law to whom the, duke was eager to show in what spirit he was contracting this alliance.
