Even the females of the North caught the epidemic spirit, and proudly betook themselves to the dangers of sea-life. Saxo-Grammaticus relates an interesting story of one of them. Alwilda, the daughter of Synardus, a Gothic king, to deliver herself from the violence imposed on her inclination, by a marriage with Alf, the son of Sygarus, king of Denmark, embraced the life of a rover; and attired as a man, she embarked in a vessel of which the crew was composed of other young women of tried courage, dressed in the same manner. Among the first of her cruises, she landed at a place where a company of pirates were bewailing the loss of their commander; and the strangers were so captivated with the air and agreeable manners of Alwilda, that they unanimously chose her for their leader. By this reinforcement she became so formidable, that Prince Alf was despatched to engage her. She sustained his attacks with great courage and talent; but during a severe action in the gulf of Finland, Alf boarded her vessel, and having killed the greatest part of her crew, seized the captain, namely herself; whom nevertheless he knew not, because she had a casque which covered her visage. The prince was agreeably surprised, on removing the helmet, to recognize his beloved Alwilda; and it seems that his valor had now recommended him to the fair princess, for he persuaded her to accept his hand, married her on board, and then led her to partake of his wealth, and share his throne.

Charlemagne, though represented as naturally generous and humane, had been induced, in his extravagant zeal for the propagation of those tenets which he had himself adopted, to enforce them throughout Germany at the point of the sword; and his murders and decimations on that account disgrace humanity. The more warlike of the Pagans flying into Jutland, from whence the Saxons had issued forth, were received with kindness, and furnished with the means of punishing their persecutor, by harassing his coasts. The maritime towns of France were especially ravaged by those pirates called "Normands," or men of the North; and it was owing to their being joined by many malcontents, in the provinces since called Normandy, that that district acquired its name. Charlemagne, roused by this effrontery, besides fortifying the mouths of the great rivers, determined on building himself a fleet, which he did, consisting of 400 of the largest galleys then known, some having five or six benches of oars. His people were, however, extremely ignorant of maritime affairs, and in the progress of having them taught, he was suddenly called to the south, by the invasion of the Saracens.
