Pitted against the ablest foe in Europe, he found himself without the sympathy and aid of those to whom alone he could look for help. Meanwhile Gregory was sending his agents to all the courts of Europe and employing every intrigue to effect the emperor’s dethronement. In 1076 a convention of princes was called to meet near Mayence, Henry not being permitted to be present. So heavy had the papal excommunication fallen by this time that the emperor sent messengers to this convention offering to submit to their demands if they would only spare his crown. Gregory was inexorable, and they adjourned without any reconciliations being effected, to meet in a few months at Augsburg. Henry now realized the might of the hand that for centuries had been silently gathering the reins of spiritual power, only to grasp at last the political supremacy as well. With the burden of excommunication ready to crush out his imperial scepter he sued for pardon at any price. The pope had retired for a time to the castle of Canossa, not far from Parma. Thither went the Franconian Emperor of Germany to implore the papal forgiveness. He presented himself before the gate barefoot, clad in a shirt of sack-cloth, and prayed that he might be received and forgiven as a penitent sinner. But Gregory chose to prolong the satisfaction he had in witnessing his penitence. So throughout the whole day, without food, in snow and rain, he stood begging the pope to receive him. In the same condition and without avail, he stood the second and the third day. Not until the morning of the fourth day did the pope admit him, and then his pardon was granted on conditions which made his crown, for the time, a dependency of the Bishop of Rome. But the struggle of the German rulers with popedom was not ended at Canossa. Henry himself renewed it a few years later with far better results to his side. The spirit of protestantism was ever alive in some form in Germany, and, as we have said, was prophetic of him who should rise in the fifteenth century and dare to protest against the claim of spiritual supremacy by the autocrat of Rome. From that time till now it has been a by-phrase with German princes in their conflicts with the church that they “will not go to Canossa.” BEFORE THE REFORMATION.
