In the meantime the terrified congregation in Sta. Maria Maggiore had recovered its senses, and messengers hurried out in all directions to trace the way by which the freebooters had gone, and to spread the news of the Pope's abduction. The storm had by this time passed over, and the people were easily roused on the eve of the great festival. Torches began to gleam by all the darkling ways, and the population poured forth in the excitement of a great event. It would seem that in all the tumultuous and factious city there was but one thought of horror at the sacrilege, and determination to save the Pope if it were still possible. Gregory was not, like his great predecessor the first of that name, the idol of his people. He had not the wealth with which many great ecclesiastics had secured the homage of the often famished crowd; and a stern man, with no special geniality of nature, and views that went so far beyond the local interests of Rome, he does not seem the kind of ruler to have secured popular favour. Yet the city had never been more unanimous, more determined in its resolution. The tocsin was sounded in all the quarters of Rome during that night of excitement; every soldier was called forth, guards were set at all the gates, lest the Pope should be conveyed out of the city; and the agitated crowd flocked to the Capitol, the only one of the seven hills of Rome where some kind of repair and restoration had been attempted, to consult, rich and poor together, people and nobles, what was to be done. To this spot came the scouts sent out in search of information, to report their discoveries. They had found that the Pope was still in Rome, and where he was—a prisoner, but as yet unharmed.

With one impulse the people of Rome, forming themselves into an undignified but enthusiastic army, rushed down from their place of meeting towards the robber's castle. We hear of engines of war, and all the cumbrous adjuncts of a siege and means of breaching the walls, as if those articles had been all ready in preparation for any emergency. The palace, though strong, could not stand the assault of the whole population, and soon it was necessary to bring the Pope from his prison and show him at a window to pacify the assailants. Cencius did all that a ruffian in such circumstances would naturally do. He first tried to extract money and lands from the Pope's terrors, and then flung himself on his knees before Gregory, imploring forgiveness and protection. The first attempt was useless, for Gregory was not afraid; the second was more successful, for remorseless to the criminals whose evil acts or example injured the Church, the Pope was merciful enough to ordinary sinners, and had never condemned any man to death. "What you have done to me I pardon you as a father; but what you have done against God and the Church must be atoned for," said Gregory, still at the mercy of any rude companion in that band of ruffians: and he commanded his captor to make a pilgrimage to Jerusalem, to cleanse himself from this sin. The Pope was conveyed out of his prison by the excited and enthusiastic crowd, shouting and weeping, half for joy, and half at sight of the still bleeding scar on his forehead. But weak and exhausted as he was, without food, after a night and almost a day of such excitement, in which he had not known from one hour to another what might happen, helpless in the hands of his enemies, Gregory had but one thought—to conclude his mass which he had not finished when he was interrupted at the altar. He went back in his cassock, covered by the stranger's furred cloak, along the same wild way over which he had been hurried in the darkness; and followed by the entire population, which swarmed into every corner and blocked every entrance, returned to the great basilica, where he once more ascended the altar steps, completed the mass, offered his thanksgivings to God, and blessed and thanked his deliverers, before he sought in the quick falling twilight of the winter day the rest of his own house.

It is common to increase the effect of this most picturesque scene by describing Gregory as an aged man, old and worn out, in the midst of his fierce foes; but he was barely sixty and still in the fulness of his strength, though spare and shrunken by many fasts and still more anxieties. That he had lost nothing of his vigour is evident, and in fact the incident, though never forgotten as a dramatic and telling episode by the historians, was a mere incident of no importance whatever in his life.

In the meantime the Emperor Henry, who had been disposed to humility and penitence by the efforts of his mother, and by the distresses of his own position during a doubtful and dangerous intestine war, in which all at the time seemed to be going against him, had subdued the Saxons and recovered the upper hand: and, thus victorious in his own country, was no longer disposed to bow his neck under any spiritual yoke. He had paid no attention to Gregory's commands in respect to simony nor to the ordinance against lay investiture which had proceeded from the Council of 1075; but had, on the contrary, filled up several bishoprics in the old way, continued to receive the excommunicated nobles, and treated Gregory's decrees as if they had never been. His indignation at the Pope's interference—that indignation which every secular prince has always shown when interfered with by the Holy See, and which so easily translates the august titles of the successor of St. Peter, the Vicar of Christ, into a fierce denunciation of the "Italian priest" whom mediæval princes feared and hated—was only intensified by his supreme pretensions as Emperor, and grew in virulence as Gregory's undaunted front and continued exercise, so far as anathemas would do it, of the weapons of church discipline, stood steadily before him. It is very possible that the complete discomfiture of Cencius's attempt upon the Pope's liberty or life, to which Henry is believed to have been accessory, and the disgrace and ridicule of that failure, irritated and exasperated the young monarch, and that he felt henceforward that no terms could be kept with the man whom he had failed to destroy.

Gregory, on the other hand, finding all his efforts unsuccessful to gain the submission of Henry, had again taken the strong step of summoning him to appear before the yearly council held in Rome at the beginning of Lent, there to answer for his indifference to its previous decisions. The following letter sent to Henry a short time after the attempt of Cencius, but in which not a word of that attempt is said, is a remarkable example of Gregory's dignified and unyielding attitude:

"Gregory, servant of the servants of God.

"To Henry, king, salutation and the blessing of the apostles, if he obeys the apostolic see, as becomes a Christian king.

"Considering with anxiety, within ourselves, to what tribunal we have to give an account of the dispensation of the ministry which has been extended to us by the Prince of the apostles, we send you with doubt our apostolic blessing, since we are assured that you live in close union with men excommunicated by the judgment of the Apostolic See and the censure of the synod. If this is true, you will yourself perceive that you cannot receive the grace of blessing either divine or apostolic, until you have dismissed from your society these excommunicated persons, or in forcing them to express their repentance have yourself obtained absolution by penitence and expiation. We counsel your highness, if you are guilty in this respect, to have recourse, without delay, to the advice of some pious bishop, who, under our authority, will direct you what to do, and absolve you, informing us with your consent of your penitence."

The Pope goes on to point out, recalling to Henry's mind the promises he had made, and the assurances given—how different his conduct has been from his professions.

"In respect to the church of Milan, how you have kept the engagements made with your mother, and with the bishops our colleagues, and with what intention you made these promises, the event itself shows. And now to add wound to wound, you have disposed of the churches of Spoleto and of Fermo. Is it possible that a man dares to transfer or give a church to persons unknown to us, while the imposition of hands is not permitted, except on those who are well known and approved? Your own dignity demands, since you call yourself the son of the Church, that you should honour him who is at her head, that is the blessed Peter, the prince of the apostles, to whom, if you are of the flock of the Lord, you have been formally confided by the voice and authority of the Lord—him to whom Christ said 'Feed my sheep.' So long as we, sinful and unworthy as we are, hold his place in his seat and apostolical government, it is he who receives all that you address to us either by writing or speech; and while we read your letters or listen to your words, it is he who beholds with a penetrating eye what manner of heart it is from which they come."
