Now for many years, Rome had been in the hands of a family of converted Jews, known as the Pierleoni, from Pietro Leone, first spoken of in the chronicles as an iniquitous usurer of enormous wealth. They became prefects of Rome; they took possession of Sant' Angelo and were the tyrants of the city, and finally they became the Pope's great enemies, the allies of Roger of Apulia, and makers of antipopes, of whom the first was either Pietro's son or his grandson. They had on their side possession, wealth, the support of a race which never looks upon apostasy from its creed as final, the alliance of King Roger and of Duke Roger, his son, and the countenance, if not the friendship, of Arnold of Brescia, the excommunicated monk of northern Italy, and the pupil of the romantic Abelard. And the Pierleoni had against them the Popes, the great Frangipani family with most of the nobles, and Saint Bernard of Clairvaux, who has been called the Bismarck of the Church. Arnold of Brescia was no ordinary fanatic. He was as brave as Stefaneschi, as pure-hearted as Stephen Porcari, as daring and eloquent as Rienzi in his best days. The violent deeds of his followers have been imputed to him, and brought him to his end; but it was his great adversary, Saint Bernard, who expressed a regretful wish 'that his teachings might have been as irreproachable as his life.' The doctrine for which he died at last was political, rather than spiritual, human rather than theological. In all but his monk's habit he was a layman in his later years, as he had been when he first wandered to France and sat at the feet of the gentle Abelard; but few Churchmen of that day were as spotless in their private lives. He was an agitator, a would-be reformer, a revolutionary; and the times craved change. The trumpet call of the first Crusade had roused the peoples of Europe, and the distracted forces of the western world had been momentarily concentrated in a general and migratory movement of religious conquest; forty years later the fortunes of the Latins in the East were already waning, and Saint Bernard was meditating the inspiring words that sent four hundred thousand warriors to the rescue of the Holy Places. What Bernard was about to attempt for Palestine, Arnold dreamed of accomplishing for Rome. In his eyes she was holy, too, her ruins were the sepulchre of a divine freedom, worthy to be redeemed from tyranny even at the price of blood, and he would have called from the tomb the spirit of murdered liberty to save and illuminate mankind. Where Bernard was a Christian, Arnold was a Roman in soul; where Bernard was an inspired monk, Arnold was in heart a Christian, of that first Apostolic republic which had all things in common.
