But to return to the point from which we deviated. The Emperor Louis, to add to the importance of his party and to receive the crown, came into Italy; and being at Milan, as an excuse for taking money of the Milanese, he pretended to make them free and to put the Visconti in prison; but shortly afterwards he released them, and, having gone to Rome, in order to disturb Italy with less difficulty, he made Piero della Corvara anti–pope, by whose influence, and the power of the Visconti, he designed to weaken the opposite faction in Tuscany and Lombardy. But Castruccio died, and his death caused the failure of the emperor's purpose; for Pisa and Lucca rebelled. The Pisans sent Piero della Corvara a prisoner to the pope in France, and the emperor, despairing of the affairs of Italy, returned to Germany. He had scarcely left, before John king of Bohemia came into the country, at the request of the Ghibellines of Brescia, and made himself lord of that city and of Bergamo. And as his entry was with the consent of the pope, although he feigned the contrary, the legate of Bologna favored him, thinking by this means to prevent the return of the emperor. This caused a change in the parties of Italy; for the Florentines and King Robert, finding the legate was favorable to the enterprises of the Ghibellines, became foes of all those to whom the legate and the king of Bohemia were friendly. Without having regard for either faction, whether Guelph or Ghibelline, many princes joined them, of whom, among others, were the Visconti, the Della Scala, Filippo Gonzao of Mantua, the Carrara, and those of Este. Upon this the pope excommunicated them all. The king, in fear of the league, went to collect forces in his own country, and having returned with a large army, still found his undertaking a difficult one; so, seeing his error, he withdrew to Bohemia, to the great displeasure of the legate, leaving only Reggio and Modena guarded, and Parma in the care of Marsilio and Piero de' Rossi, who were the most powerful men in the city. The king of Bohemia being gone, Bologna joined the league; and the leaguers divided among themselves the four cities which remained of the church faction. They agreed that Parma should pertain to the Della Scalla; Reggio to the Gonzaga; Modena to the family of Este, and Lucca to the Florentines. But in taking possession of these cities, many disputes arose which were afterward in a great measure settled by the Venetians. Some, perhaps, will think it a species of impropriety that we have so long deferred speaking of the Venetians, theirs being a republic, which, both on account of its power and internal regulations, deserves to be celebrated above any principality of Italy. But that this surprise may cease when the cause is known, I shall speak of their city from a more remote period; that everyone may understand what were their beginnings, and the causes which so long withheld them from interfering in the affairs of Italy.
When Attila, king of the Huns, besieged Aquileia, the inhabitants, after defending themselves a long time, began to despair of effecting their safety, and fled for refuge to several uninhabited rocks, situated at the point of the Adriatic Sea, now called the Gulf of Venice, carrying with them whatever movable property they possessed. The people of Padua, finding themselves in equal danger, and knowing that, having became master of Aquileia, Attila would next attack themselves, also removed with their most valuable property to a place on the same sea, called Rivo Alto, to which they brought their women, children, and aged persons, leaving the youth in Padua to assist in her defense. Besides these, the people of Monselice, with the inhabitants of the surrounding hills, driven by similar fears, fled to the same rocks. But after Attila had taken Aquileia, and destroyed Padua, Monselice, Vicenza, and Verona, the people of Padua and others who were powerful, continued to inhabit the marshes about Rivo Alto; and, in like manner, all the people of the province anciently called Venetia, driven by the same events, became collected in these marshes. Thus, under the pressure of necessity, they left an agreeable and fertile country to occupy one sterile and unwholesome. However, in consequence of a great number of people being drawn together into a comparatively small space, in a short time they made those places not only habitable, but delightful; and having established among themselves laws and useful regulations, enjoyed themselves in security amid the devastations of Italy, and soon increased both in reputation and strength. For, besides the inhabitants already mentioned, many fled to these places from the cities of Lombardy, principally to escape from the cruelties of Clefis king of the Lombards, which greatly tended to increase the numbers of the new city; and in the conventions which were made between Pepin, king of France, and the emperor of Greece, when the former, at the entreaty of the pope, came to drive the Lombards out of Italy, the duke of Benevento and the Venetians did not render obedience to either the one or the other, but alone enjoyed their liberty. As necessity had led them to dwell on sterile rocks, they were compelled to seek the means of subsistence elsewhere; and voyaging with their ships to every port of the ocean, their city became a depository for the various products of the world, and was itself filled with men of every nation.
For many years the Venetians sought no other dominion than that which tended to facilitate their commercial enterprises, and thus acquired many ports in Greece and Syria; and as the French had made frequent use of their ships in voyages to Asia, the island of Candia was assigned to them in recompense for these services. While they lived in this manner, their name spread terror over the seas, and was held in veneration throughout Italy. This was so completely the case, that they were generally chosen to arbitrate in controversies between the states, as occurred in the difference between the Colleagues, on account of the cities they had divided among themselves; which being referred to the Venetians, they awarded Brescia and Bergamo to the Visconti. But when, in the course of time, urged by their eagerness for dominion, they had made themselves masters of Padua, Vicenza, Trevisa, and afterward of Verona, Bergamo, and Brescia, with many cities in Romagna and the kingdom of Naples, other nations were impressed with such an opinion of their power, that they were a terror, not only to the princes of Italy, but to the ultramontane kings. These states entered into an alliance against them, and in one day wrested from them the provinces they had obtained with so much labor and expense; and although they have in latter times reacquired some portions, still possessing neither power nor reputation, like all the other Italian powers, they live at the mercy of others.
