During a period of two hundred years, Italy was unequally divided between the kingdom of the Lombards and the exarchate of Ravenna. The offices and professions, which the jealousy of Constantine had separated, were united by the indulgence of Justinian; and eighteen successive exarchs were invested, in the decline of the empire, with the full remains of civil, of military, and even of ecclesiastical, power. Their immediate jurisdiction, which was afterwards consecrated as the patrimony of St. Peter, extended over the modern Romagna, the marshes or valleys of Ferrara and Commachio, five maritime cities from Rimini to Ancona, and a second inland Pentapolis, between the Adriatic coast and the hills of the Apennine. Three subordinate provinces, of Rome, of Venice, and of Naples, which were divided by hostile lands from the palace of Ravenna, acknowledged, both in peace and war, the supremacy of the exarch. The duchy of Rome appears to have included the Tuscan, Sabine, and Latin conquests, of the first four hundred years of the city, and the limits may be distinctly traced along the coast, from Civita Vecchia to Terracina, and with the course of the Tyber from Ameria and Narni to the port of Ostia. The numerous islands from Grado to Chiozza composed the infant dominion of Venice: but the more accessible towns on the Continent were overthrown by the Lombards, who beheld with impotent fury a new capital rising from the waves. The power of the dukes of Naples was circumscribed by the bay and the adjacent isles, by the hostile territory of Capua, and by the Roman colony of Amalphi, whose industrious citizens, by the invention of the mariner's compass, have unveiled the face of the globe. The three islands of Sardinia, Corsica, and Sicily, still adhered to the empire; and the acquisition of the farther Calabria removed the landmark of Autharis from the shore of Rhegium to the Isthmus of Consentia. In Sardinia, the savage mountaineers preserved the liberty and religion of their ancestors; and the husbandmen of Sicily were chained to their rich and cultivated soil. Rome was oppressed by the iron sceptre of the exarchs, and a Greek, perhaps a eunuch, insulted with impunity the ruins of the Capitol. But Naples soon acquired the privilege of electing her own dukes: the independence of Amalphi was the fruit of commerce; and the voluntary attachment of Venice was finally ennobled by an equal alliance with the Eastern empire. On the map of Italy, the measure of the exarchate occupies a very inadequate space, but it included an ample proportion of wealth, industry, and population. The most faithful and valuable subjects escaped from the Barbarian yoke; and the banners of Pavia and Verona, of Milan and Padua, were displayed in their respective quarters by the new inhabitants of Ravenna. The remainder of Italy was possessed by the Lombards; and from Pavia, the royal seat, their kingdom was extended to the east, the north, and the west, as far as the
