The enormous influence exercised by these preachers made it important, both for the clergy and for the government, at least not to have them as opponents; one means to this end was to permit only monks or priests who had received at all events the lesser consecration, to enter the pulpit, so that the Order or Corporation to which they belonged was, to some extent, responsible for them. But it was not easy to make the rule absolute, since the Church and pulpit had long been used as a means of publicity in many ways, judicial, educational, and others, and since even sermons were sometimes delivered by humanists and other laymen. There existed, too, in Italy, a dubious class of persons who were neither monks nor priests, and who yet had renounced the world - that is to say, the numerous class of hermits who appeared from time to time in the pulpit on their own authority, and often carried the people with them. A case of this kind occurred at Milan in 1516 after the second French conquest, certainly at a time when public order was much disturbed. A Tuscan hermit, Hieronymus of Siena, possibly an adherent of Savonarola, maintained his place for months together in the pulpit of the Cathedral, denounced the hierarchy with great violence, caused a new chandelier and a new altar to be set up in the church, worked miracles, and only abandoned the field after a long and desperate struggle. During the decades in which the fate of Italy was decided, the spirit of prophecy was unusually active, and nowhere where it displayed itself was it confined to any one particular class. We know with what a tone of true prophetic defiance the hermits came forward before the sack of Rome. In default of any eloquence of their own, these men made use of messengers with symbols of one kind or another, like the ascetic near Siena (1496) who sent a 'little hermit,' that is a pupil, into the terrified city with a skull upon a pole to which was attached a paper with a threatening text from the Bible.
