The appeal to Rome was necessary, as the Archbishop and a large party of the citizens, together with all the clergy, had denounced Ariald and Landulf as Patarines. The fact was notorious that the secret and suspected Manichees in Milan were now holding up their heads and defying those who had hitherto controlled them. The Manichees suddenly found that from proscribed heretics they had been exalted into champions of orthodoxy. It was a satisfactory change for those who had been persecuted to become persecutors, and turn their former tyrants into victims. But now, to the confusion and dismay of the clergy, they found themselves betrayed by the Pope, and at the mercy of those who had old wrongs to resent. Fortified with the blessing of the Pope on his work, his orthodoxy triumphantly established by the supreme authority, Ariald rushed back to Milan, accompanied by papal legates to protect him, and proclaim his mission as divine. He was unmeasured in his denunciations. Dissension fast ripened into civil war. Ariald, at the head of a roaring mob, swept the clergy together into a church, and producing a paper which bound all of them by oath to put away their wives, endeavoured to enforce their subscription. A priest, maddened to resentment, struck the demagogue in the mouth. This was the signal for a general tumult. The adherents of Ariald rushed through the streets, the alarm bells pealed, the populace gathered from all quarters, and a general hunting down of the married clergy ensued. "How can the blind lead the blind?" preached Landulf Cotta. "Let these Simoniacs, these Nicolaitans be despised. You who wish to have salvation from the Lord, drive them from their functions; esteem their sacrifices as dogs' dung (_canina stercora_)! Confiscate their goods, and every one of you take what he likes![19] We can imagine the results of such license given to the lowest rabble. The nobles, over-awed, dared not interfere.

It is necessary not to confound Landulf Cotta, the demagogue, with Landulf the elder, the historian, and Landulf the younger, the disciple and biographer of Ariald. Nor were the clergy of the city alone exposed to this popular persecution. The preachers roved round the country, creating riots everywhere. This led to retaliation, but retaliation of a feeble, harmless sort. A chapel built by Ariald on his paternal estate was pulled down; and the married clergy resentfully talked of barking his chestnut trees and breaking down his vines, but thought better of it, and refrained. A more serious attempt at revenge was the act of a private individual. Landulf Cotta was praying in a church, when a priest aimed at him with a sword, but without seriously hurting him. A cripple at the church door caught the flying would-be assassin; a crowd assembled, and Landulf with difficulty extricated the priest alive from their hands.
