But perhaps it may be said the popes were not responsible for all this. Let it be remembered that in less than one hundred and forty years the city had been successively taken by Alaric, Genseric, Rieimer, Vitiges, Totila; that many of its great edifices had been converted into defensive works. The aqueducts were destroyed by Vitiges, who ruined the Campagna; the palace of the Caesars was ravaged by Totila; then there had been the Lombard sieges; then Robert Guiscard and his Normans had burnt the city from the Antonine Column to the Flaminian Gate, from the Lateran to the Capitol; then it was sacked and mutilated by the Constable Bourbon; again and again it was flooded by inundations of the Tiber and shattered by earthquakes. We must, however, bear in mind the accusation of Machiavelli, who says, in his "History of Florence," that nearly all the barbarian invasions of Italy were by the invitations of the pontiffs, who called in those hordes! It was not the Goth, nor the Vandal, nor the Norman, nor the Saracen, but the popes and their nephews, who produced the dilapidation of Rome! Lime-kilns had been fed from the ruins, classical buildings had become stone-quarries for the palaces of Italian princes, and churches were decorated from the old temples. Churches decorated from the temples! It is for this and such as this that the popes must be held responsible. Superb Corinthian columns bad been chiseled into images of the saints. Magnificent Egyptian obelisks had been dishonored by papal inscriptions. The Septizonium of Severus had been demolished to furnish materials for the building of St. Peter's; the bronze roof of the Pantheon had been melted into columns to ornament the apostle's tomb. The great bell of Viterbo, in the tower of the Capitol, had announced the death of many a pope, and still desecration of the buildings and demoralization of the people went on. Papal Rome manifested no consideration, but rather hatred, for classical Rome, The pontiffs had been subordinates of the Byzantine sovereigns, then lieutenants of the Frankish kings, then arbiters of Europe; their government had changed as much as those of any of the surrounding nations; there had been complete metamorphoses in its maxims, objects, claims. In one point only it had never changed--intolerance. Claiming to be the centre of the religious life of Europe, it steadfastly refused to recognize any religious existence outside of itself, yet both in a political and theological sense it was rotten to the core. Erasmus and Luther heard with amazement the blasphemies and witnessed with a shudder the atheism of the city.
