Neither Herlembald nor Ariald seems to have been prepared for the bold action of the Archbishop. On the appointed day the cathedral was filled with substantial citizens and nobles. Herlembald missed the wolfish eyes, ragged hair, and hollow cheeks of his sectaries, and, fearing danger, leaped over the chancel rails, and took up his position near the altar. The Archbishop mounted the ambone with the bull of excommunication in his hand. "See!" he exclaimed, "this is the result of the turbulence of these demagogues, Ariald and Herlembald. This city, out of reverence to St. Ambrose, has never obeyed the Roman Church. Shall we be crushed? Take away out of the land of the living these disturbers of the public peace who labour day and night to rob us of our ancient liberties." He was interrupted by a shout of "Let them be killed." Guido paused, and then cried out, "All who honour and cleave to St. Ambrose, leave the church, that we may know who are our adversaries." Instantly from the doors rolled out the dense crowd, seven hundred in number, according to the estimation of Andrew, the biographer of Ariald. Only twelve men were left within who stood firm to the Patarine cause. Ariald had, in the meantime, taken refuge in the choir beside Herlembald. The clergy selected Ariald, the laity Herlembald, for their victims. Ariald was dragged from the church, severely wounded. Herlembald escaped better; using his truncheon, he beat off his assailants till he had climbed to a place of safety, whence he could not be easily dislodged. As night fell, the Patarines gathered, stormed, and pillaged the palace of the Archbishop, and, bursting into the church, liberated Herlembald. Guido hardly escaped on horseback, sorely maltreated in the tumult. His adherents fled like smoke before the tempest. Ariald was found bleeding and faint, and was conveyed by the multitude in triumph to the church of St. Sepolcro. Then Herlembald called to the roaring mob to be still. "Let us ask Master Ariald whose house is to be first given up to sack." But Ariald earnestly dissuaded from further violence, and entreated the vehement dictator to spare the lives and property of their enemies.
