Harald the Valiant was one of the most eminent adventurers of his age. He had slain mighty men; and after sweeping the seas of the north as a conqueror, he descended to the Mediterranean, and the shores of Africa. But a greater power now opposed him, and he was taken prisoner, and detained for some time at Constantinople. He endeavoured to beguile his gloomy solitude by song; but his muse gave him no joy, for he complains that the reputation he had acquired by so many hazardous exploits, by his skill in single combat, riding, swimming, gliding along the ice, darting, rowing, and guiding a ship through the rocks, had not been able to make any impression on Elissiff, or Elizabeth, the beautiful daughter of Yarilas, king of Russia.[19] [Sidenote: The Age of Charlemagne.] Such were the features of the ancient character of Europe, that formed the basis of the chivalry of the middle ages; such was chivalry in its rude, unpolished state, the general character of the whole people, rather than the moral chastener of turbulence and ferocity. From receiving his weapons in an assembly of the nation; associating in clans; protecting and revering women; performing acts of service, when affection and duty commanded them: from these simple circumstances and qualities, the most beautiful form of manners arose, that has ever adorned the history of man. It is impossible to mark the exact time when these elements were framed into that system of thought and action which we call Chivalry. Knighthood was certainly a feature and distinction of society before the days of Charlemagne, and its general prevalence in his time is very curiously proved, by the permission which he gave to the governor of Friesland to make knights, by girding them with a sword, and giving them a blow.[20] [Sidenote: Chivalry modified by Religion.]
