The principal feature of his history which concerns us is the good-natured indifference with which Alexander VI. endured his repeated attacks on the scandals and vices of the papal court. There were so many political interests entangled in Savonarola’s career that it is not always easy to reach the hidden springs of action at work, but it may be assumed that Alexander, if left to himself, would have allowed the reformer to declaim unmolested. More than once he interdicted the Dominican from preaching and ordered him to Rome, but took little heed of disobedience. At length he launched an excommunication, which for nearly a year received as little respect as his previous orders, and when at length a sudden revulsion of feeling among the Florentine mob enabled him to dispose of his adversary under the forms of law, it is probable that even then he would not have pushed matters to such extremity had not Savonarola been led to an act of aggressive rebellion. The Duke of Milan forwarded to the pope intercepted letters in which the reformer, by command of God, urged the monarchs of Europe to call a general council under pretext that the church was without a head, since Alexander was an infidel who had obtained the tiara by simony and had polluted it with unimaginable vices. In his capacity of prophet, Savonarola promised the rulers triumph over their enemies if they would aid in the good work of cleansing the church, and he engaged to prove before the council the truth of his allegations by working miracles.[961] It would probably be unjust to condemn him as an imposter, but such conclusion is only to be escaped by pronouncing him partially insane. That fierce age was not apt to invoke such considerations in palliation of so flagrant an attempt at revolution, and Savonarola was doomed. * * * * * While thus trampling out these successive revolts, the church was blind to the lesson taught by their perpetual recurrence. The minds of men were gradually learning to estimate at its true value the claim of the hierarchy to veneration, and at the same time the vices of the establishment were yearly becoming more odious, and its oppression more onerous. The explosion might be delayed by attempts at partial reformation, but it was inevitable. XXIV. THE FIFTEENTH CENTURY.
