The great Gerbert, Pope in the year 1000 under the name of Sylvester II, stands as a symbol. Great as an intriguer, to us he is even greater as a scholar. He had studied mathematics and “al-gebra” (the word is Arabic) with the Arabs in Spain, and like every scholar worthy of the name he loved the classics. His mathematics made him feared as a wizard, and when writing to a friend in Italy for unchurchly, Latin books, we find him asking that they be “procured quietly,” promising that he will tell no one of the favour done him. I have called Gerbert a symbol of his time. To call that time the “Dark Ages” is just to a degree that few of the stock epithets of our school are just. They were the morasses from which the Mediæval rise begins. For, after the doubtful pause of which I have spoken, Europe arose. The Normans conquer England and Sicily, and set up systems of government and administration fit to be models for all the West. The Hildebrandine reforms free the Church from the feudal anarchy, and the Church in her new strength fills Christendom with a new sense of unity and common purpose. This common purpose hurls Europe against Asia, in the tidal wave of the First Crusade, which breaks down the barrier between East and West and begins a new day. It is important to note how short was this Norman-Hildebrandine period, and how many-sided was its accomplishment. At the most it covered less than fifty years in time. The first stroke of the Church to make itself independent of the State comes after the mid-century. The Normans conquer England in the familiar year 1066. The Crusade mobilized in 1096 and returned in 1099. Thus, if we take the Church, the Crusaders were a trifle nearer in time to the period in which she was the submissive creature of lay government than an American of the Great War is to the War of Secession. They were distant from the conquest of England about as we (1920) are from M’Kinley’s first election and the prosperity that came with it. Of course there had been preparation. William the Conqueror found London already so large that his troops could not even blockade it. The Italian sea-faring republics were already turning the tables on the Saracen in the Mediterranean in the early part of the century. Nevertheless, the phase of the first great struggles and great accomplishment falls into the little space of years I have marked out. It is an astonishing time. In moral purpose, the haphazard speech of to-day would say in “Idealism,” this short period stands supreme in all our long tradition. The First Crusade proves it. Whether or not Hildebrand’s new insistence upon the celibacy of priests and upon private, specific confession were in themselves good, we need not discuss. At any rate, never before or since, not even in the great war just over, has Christendom put forth such an effort as the First Crusade.
