It is curious to observe the manner in which, under the influence of the prevailing tendency, the career of Charlemagne was transfigured by the popular imagination. His military enterprises had been chiefly directed against the Saxons, against whom he had made not less than thirty-two expeditions. With the Mohammedans he had but little contact. It was Charles Martel, not his grandson, who, by the great battle of Poitiers, had checked their career. Charlemagne made, in person, but a single expedition against them in Spain, and that expedition was on a small scale, and was disastrous in its issue. But in the Carlovingian romances, which arose at a time when the enthusiasm of the Crusades was permeating Christendom, events were represented in a wholly different light. Charles Martel has no place among the ideal combatants of the Church. He had appeared too early, his figure was not sufficiently great to fascinate the popular imagination, and by confiscating ecclesiastical property, and refusing to assist the Pope against the Lombards, he had fallen under the ban of the clergy. Charlemagne, on the other hand, was represented as the first and greatest of the crusaders. His wars with the Saxons were scarcely noticed. His whole life was said to have been spent in heroic and triumphant combats with the followers of Mohammed.(549) Among the achievements attributed to him was an expedition to rescue Nismes and Carcassonne from their grasp, which was, in fact, a dim tradition of the victories of Charles Martel.(550) He is even said to have carried his victorious arms into the heart of Palestine, and he is the hero of what are probably the three earliest extant romances of the Crusades.(551) In fiction, as in history, his reign forms the great landmark separating the early period of the middle ages from the age of military Christianity.
