The danger to the hierarchy was indeed formidable. Only one transalpine nation had emerged from barbarism; and that nation had thrown off all respect for Rome. Only one of the vernacular languages of Europe had yet been extensively employed for literary purposes; and that language was a machine in the hands of heretics. The geographical position of the sectaries made the danger peculiarly formidable. They occupied a central region communicating directly with France, with Italy, and with Spain. The provinces which were still untainted were separated from each other by this infected district. Under these circumstances, it seemed probable that a single generation would suffice to spread the reformed doctrine to Lisbon, to London, and to Naples. But this was not to be. Rome cried for help to the warriors of northern France. She appealed at once to their superstition and to their cupidity. To the devout believer she promised pardons as ample as those with which she had rewarded the deliverers of the Holy Sepulchre. To the rapacious and profligate she offered the plunder of fertile plains and wealthy cities. Unhappily, the ingenious and polished inhabitants of the Languedocian provinces were far better qualified to enrich and embellish their country than to defend it. Eminent in the arts of peace, unrivalled in the "gay science," elevated above many vulgar superstitions, they wanted that iron courage, and that skill in martial exercises, which distinguished the chivalry of the region beyond the Loire, and were ill fitted to face enemies who, in every country from Ireland to Palestine, had been victorious against tenfold odds. A war, distinguished even among wars of religion by merciless atrocity, destroyed the Albigensian heresy, and with that heresy the prosperity, the civilization, the literature, the national existence, of what was once the most opulent and enlightened part of the great European family. Rome, in the meantime, warned by that fearful danger from which the exterminating swords of her crusaders had narrowly saved her, proceeded to revise and to strengthen her whole system of polity. At this period were instituted the Order of Francis, the Order of Dominic, the Tribunal of the Inquisition. The new spiritual police was everywhere. No alley in a great city, no hamlet on a remote mountain, was unvisited by the begging friar. The simple Catholic, who was content to be no wiser than his fathers, found, wherever he turned, a friendly voice to encourage him. The path of the heretic was beset by innumerable spies; and the Church, lately in danger of utter subversion, now appeared to be impregnably fortified by the love, the reverence, and the terror of mankind.
