But it was especially from Milan[25] that they spread abroad over all the Peninsula, making proselytes even in the most remote districts of Calabria. The state of anarchy prevailing in the country was very favorable to them. The papacy was too much occupied in baffling the spasmodic efforts of the Hohenstaufen, to put the necessary perseverance and system into its struggles against heresy. Thus the new ideas were preached under the very shadow of the Lateran; in 1209, Otho IV., coming to Rome to be crowned, found there a school in which Manicheism was publicly taught.[26] With all his energy Innocent III. had not been able to check this evil in the States of the Church. The case of Viterbo tells much of the difficulty of repressing it; in March, 1199, the pope wrote to the clergy and people of this town to recall to their minds, and at the same time to increase, the penalties pronounced against heresy. For all that, the Patarini had the majority in 1205, and succeeded in naming one of themselves consul.[27] The wrath of the pontiff at this event was unbounded; he fulminated a bull menacing the city with fire and sword, and commanding the neighboring towns to throw themselves upon her if within a fortnight she had not given satisfaction.[28] It was all in vain: the Patarini were dealt with only as a matter of form; it needed the presence of the pope himself to assure the execution of his orders and obtain the demolition of the houses of the heretics and their abettors (autumn of 1207).[29] But stifled at one point the revolt burst out at a hundred others; at this moment it was triumphant on all sides; at Ferrara, Verona, Rimini, Florence, Prato, Faenza, Treviso, Piacenza. The clergy were expelled from this last town, which remained more than three years without a priest.[30] Viterbo is twenty leagues from Assisi, Orvieto only ten, and disturbances in this town were equally grave. A noble Roman, Pietro Parentio, the deputy of the Holy See in this place, endeavored to exterminate the Patarini. He was assassinated.[31] But Francis needed not to go even so far as Orvieto to become acquainted with heretics. In Assisi the same things were going on as in the neighboring cities. In 1203 this town had elected for podesta a heretic named Giraldo di Gilberto, and in spite of warnings from Rome had persisted in keeping him at the head of affairs until the expiration of his term of office (1204). Innocent III., who had not yet been obliged to use vigor with Viterbo, resorted to persuasion and despatched to Umbria the Cardinal Leo di Santa Croce, who will appear more than once in this history.[32] The successor of Giraldo and fifty of the principal citizens made the _amende honorable_ and swore fidelity to the Church. It is easy to perceive in what a state of ferment Italy was during these early years of the thirteenth century. The moral discredit of the clergy must have been deep indeed for souls to have turned toward Manicheism with such ardor.
