Frederick at first opposed all his strength of soul against the sentence of excommunication pronounced by the council on him. Causing his jewels to be brought him, and placing the golden crown of the empire on his head, he declared before a numerous assembly that he would still wear it, and knew how to defend it; but, notwithstanding the enthusiasm of the Ghibelline party, the devotion of his friends, and the progress of philosophical opinions, which he had himself encouraged, the man whom the church had condemned was in constant danger of being abandoned or betrayed. The mendicant monks everywhere excited conspiracies against him. They took advantage of the terrors inspired by sickness and age, to make sinners return, as they said, to the ways of salvation, and desired them to make amends for their past transgressions by delivering the church of God from its most dangerous enemy. Insurrections frequently broke forth in one or other of the Two Sicilies; still oftener the emperor discovered amongst his courtiers plots to destroy him, either by the dagger or poison; even his private secretary, his intimate friend, Pietro delle Vigne, whom he had raised from abject poverty, to whom he had entrusted his most important affairs, gave ear to the counsel of the monks, and promised to poison his master. [Sidenote: [1245-1248 A.D.]] Frederick, on his part, became suspicious and cruel; his distrust fell on his most faithful friends; and the executions which he ordered sometimes preceded the proofs of guilt. He had confided Germany to his son Conrad, and the exclusive government of the Veronese marches to Ezzelino. The hatred which this ferocious man excited by his crimes fell on the emperor. Ezzelino imprisoned in the most loathsome dungeons those whom he considered his enemies, and frequently put them to death by torture, or suffered them to perish by hunger; he was well aware that the relatives of these victims must also be his enemies; they were, in their turn, arrested; and the more he sacrificed to his barbarity, the more he was called upon to strike. The citizens of Milan, Mantua, Bergamo, and Brescia every day heard of new and horrible crimes committed by the governor of the marches; they conceived the greater detestation of the Ghibelline party, and entertained the firmer determination to repel Frederick. He, on the contrary, had no thoughts of attacking them; he established himself during the Council of Lyons at Turin, and thence entered into a negotiation with St. Louis, to obtain by his mediation a reconciliation with the church to which he made, in token of his submission, the offer to accompany Louis to the Holy Land.
