This legation from Pope Stephen II. took place in the year 753. The emperor Constantino Kopronymus was not the man to save Italy from the Lombards. To the repeated requests of the Pope he sent no other help than imperial letters, charging him to induce Aistulf to restore the provinces he had taken from the empire, and to Aistulf in the same sense, calling him to undo his diabolical aggression. The emperor also left the Pope free to unite himself with any one who could defend him. It was a natural right in such a case: but the imperial sanction made it more easy of success. “Then,” says Anastasius,(186) “the most holy man having, in vain, sought, by innumerable presents, to conciliate that pestilent king for the flocks committed to him by God, that is, for the whole army at Ravenna and all the people of that province of Italy, of which he was in possession, and seeing especially that there was no help from the imperial power, as his predecessors of blessed memory, the second and third Gregories and Zacharias, begged help from the king of the Franks against the oppressions and invasions which they had suffered in this Roman province from the abominable Lombard race; so he in like manner, by the inspiration of divine grace, sent in his deep sorrow a letter by a foreign hand to Pipin, king of the Franks.” Thus from 726, the beginning of the Iconoclastic heresy and tyranny of the emperors Leo III. and Kopronymus, the Popes acknowledged the Byzantine sovereignty until in 753 the direct attack of the Lombard king Aistulf upon Rome, and the attempt to make himself sovereign of the Popes of Rome and of the territory called its duchy, together with the impotence of the Byzantine emperor to defend his own subjects, and the Pope himself vainly entreating succour from him, compelled Stephen II. “to turn his thoughts from the East to the West”.(187)
