the papal letter, this being the great ecclesiastical crime which came immediately under the cognizance of the Pope. This citation addressed to the greatest monarch then existing, and by a power but barely escaped from his authority and still owing to him a certain allegiance, was enough to thrill the world from end to end. Such a thing had never happened in the knowledge of man. But before we begin so much as to hear of the effect produced, the Pope who had, nominally at least, issued the summons, the good and saintly Alexander II., after holding the papacy for twelve years, died on the 21st of April, 1073. His reign for that time had been to a great degree the reign of Hildebrand, the ever watchful, ever laborious archdeacon, who, let the Pope travel as he liked--and his expeditions through Italy were many--was always vigilant at his post, always in the centre of affairs, with eyes and ears open to everything, and a mind always intent on its purpose. Hildebrand's great idea of the position and duties of the Holy See had developed much in those twelve years. It had begun to appear a fact, in the eyes of those especially who had need of its support. The Normans everywhere believed and trusted in it, with good secular reason for so doing, and they were at the moment a great power in the earth, especially in Italy. If it had not already acquired an importance and force in the thoughts of men, more subtle and less easy to obtain than external power, it would have been impossible for the boldest to launch forth a summons to the greatest king of Christendom the future Emperor. Already the first step towards that great visionary sway, of which poets and sages, as well as ecclesiastics, so long had dreamed, had been made.
