Here it also exercised its magic charm, and the king would sit for hours gazing into the waters of the lake, as though spell-bound. But this legend cannot disguise the weak side of Charlemagne’s character, and we can only turn from it and fix our attention upon his great career. He was one of the wisest and most powerful of kings. His life was one of constant war. He fought the Saxons for thirty-three years, but at last he conquered Witikind, the great Saxon leader, in 785, and persuaded him to be baptized. Charlemagne made him Duke of Saxony, and he lived in good faith to the new vows he had taken. Notwithstanding this victory over the Saxons, Charlemagne foresaw the evils which should come upon Europe through the formidable Northmen. The monk of St. Gall relates this incident: “Charlemagne arrived unexpectedly in a certain town of Narbonnese Gaul. Whilst he was at dinner, and was as yet unrecognized of any, some corsairs of the Northmen came to ply their piracies in the very port. When their vessels were descried, they were supposed to be Jewish traders according to some, African according to others, and British in the opinion of others; but the gifted monarch perceiving by the build and lightness of the craft that they bare not merchandise, but foes, said to his own folk, ‘These vessels be not laden with merchandise, but manned with cruel foes.’ At these words, all the Franks, in rivalry one with another, ran to their ships, but uselessly, for the Northmen, indeed, hearing that yonder was he whom it was still their wont to call Charles the Hammer, feared lest all their fleet should be taken or destroyed in the port, and they avoided by a flight of inconceivable rapidity not only the blows, but even the eyes of those who were pursuing them. “Pious Charles, however, a prey to well-grounded fear, rose up from table, stationed himself at a window looking eastward, and there remained a long while, and his eyes were filled with tears. As none durst question him, this warlike prince explained to the grandees who were about his person the cause of his movement and of his tears. ‘Know ye, my lieges, wherefore I weep so bitterly? Of a surety I fear not lest these fellows should succeed in injuring me by their miserable piracies; but it grieveth me deeply that whilst I live, they should have been nigh to touching at this shore, and I am a prey to violent sorrow when I foresee what evils they will heap upon my descendants and their people.’”
