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.
