"C.E.964, Emperor ... at the request of popes] returned the hostages to the Romans. These, however, who were ungrateful for such favours, admitted, when the emperor was still not far from the city, John, also called Octavian, into the city, and without fear violated their allegiance to the emperor and the pope. Pope Leo, on the other hand, barely escaped, destitute of all means, and accompanied only by a few, marched to the emperor."
