But this religious fervor was the illusion, perhaps the artifice, of the moment; the sense of interest is strong and lasting; the love of arms and rapine was congenial to the Lombards; and both the prince and people were irresistibly tempted by the disorders of Italy, the nakedness of Rome, and the unwarlike profession of her new chief.

On the first edicts of the emperor, they declared themselves the champions of the holy images: Liutprand invaded the province of Romagna, which had already assumed that distinctive appellation; the Catholics of the Exarchate yielded without reluctance to his civil and military power; and a foreign enemy was introduced for the first time into the impregnable fortress of Ravenna.

That city and fortress were speedily recovered by the active diligence and maritime forces of the Venetians; and those faithful subjects obeyed the exhortation of Gregory himself, in separating the personal guilt of Leo from the general cause of the Roman empire.

The Greeks were less mindful of the service, than the Lombards of the injury: the two nations, hostile in their faith, were reconciled in a dangerous and unnatural alliance: the king and the exarch marched to the conquest of Spoleto and Rome: the storm evaporated without effect, but the policy of Liutprand alarmed Italy with a vexatious alternative of hostility and truce.

His successor Astolphus declared himself the equal enemy of the emperor and the pope: Ravenna was subdued by force or treachery, and this final conquest extinguished the series of the exarchs, who had reigned with a subordinate power since the time of Justinian and the ruin of the Gothic kingdom.
