The Lombards had invaded Italy in the year 568, and for nearly two centuries from that time there had been waged a kind of triangular contest which, to compare great things with small, was like the litigation which might go on in an English parish between an absentee landlord, a big Nonconformist farmer, and a cultured but acquisitive parson. The Emperor was the great absentee. Though still always spoken of as Emperor of Rome, he had been in fact for some centuries an absolutely Oriental Sovereign. Since the deposition of Romulus Augustulus in 476, no Roman Emperor had touched the soil of Italy save for one brief and most unwelcome visit paid by Constance II. in 663. The Imperial dominion in the peninsula was by this time limited to the Venetian islands, two provinces on the Adriatic coast called the Exarchate of Ravenna and the Pentapolis, the city of Hydruntum (Otranto), the province of Bruttii at the very end of the peninsula, Paestum, Naples and the duchy of Rome, which included the city of Rome, the present province of Latium and a little bit of Etruria. This scattered and fragmentary dominion, which as will be seen was almost entirely confined to the sea-coast, and embraced only a part of that, was ruled by an imperial lieutenant who bore the title of Exarch, and whose seat of government was the strong, almost impregnable, city of Ravenna. Far the largest part of Italy, including all the fertile valley of the Po, all the central chain of the Apennines and the valleys leading from them, the greater part of Tuscany and almost the whole of Apulia, was in the possession of the rough and masterful Lombards, who had been fierce savages when they entered Italy, but who had lost most of their savagery and some of their warlike vigor by long residence in the delightful land and by contact with the vestiges of Roman civilization. Arians for the most part, and even with some heathens among them at the time of their first invasion, they had now embraced the Catholic faith, were generous benefactors of the Church, and desired to be considered her dutiful sons. But still the remembrance of their old heresies continued, and whenever the political interests of the King of the Lombards clashed with those of the Pope of Rome--and they did clash as often and as irreconcilably as do those of pope and king at the present day--the old epithets “unspeakable,” “sacrilegious,” “diabolical,” flowed from the pens of the scribes in the papal chancery as freely as they had flowed when the Lombards were yet idolaters.
