Niccolò Machiavelli

“ But the Lombards having taken possession, and Italy being divided into many parts, the pope had an opportunity of greater exertion. Being as it were the head of Rome, both the emperor of Constantinople and the Lombards respected him; so that the Romans, by his means, entered into league with the Lombards, and with Longinus, not as subjects, but as equals. Thus the popes, at one time friends of the Greeks, and at another of the Lombards, increased their own power; but upon the ruin of the eastern empire, which occurred during the time of Heraclius, their influence was reduced ”

“ The pope requested assistance of Charles, who, having crossed the Alps, besieged Desiderius in Pavai, where he took both him and his children, and sent them prisoners to France. He then went to visit the pontiff at Rome, where he declared, THAT THE POPE, BEING VICAR OF GOD, COULD NOT BE JUDGED BY MEN. The pope and the people of Rome made him emperor; and thus Rome began to have an emperor of the west. ”

“ Gregory accordingly went to France, passing uninjured through the country of his enemies, so great was the respect they had for religion, and was treated honorably by Pepin, who sent an army into Italy, and besieged the Lombards in Pavia. King Astolphus, compelled by necessity, made proposals of peace to the French, who agreed to them at the entreaty of the pope—for he did not desire the death of his enemy, but that he should be converted and live. ”
