[31] The following story exhibits the influence of witchcraft among the followers of Odin. Towards the end of the tenth century, the dreaded Jomsburg sea-rovers had set out on one of their periodical expeditions, and were devastating with fire and sword the coast of Norway. A celebrated Norwegian Jarl, Hakon, collected all his forces, and sailed with a fleet of 150 vessels to encounter the pirates. Hakon, after trying in vain to break through the hostile line, retired with his fleet to the coast, and proceeded to consult a well-known sorceress in whom he had implicit confidence for any emergency. With some pretended reluctance the sorceress at length informed him that the victory could be obtained only by the sacrifice of his son. Hakon hesitated not to offer up his only son as a propitiatory sacrifice; after which, returning to his fleet, and his accustomed post in the front ranks of the battle, he renewed the engagement. Towards evening the Jomsburg pirates were overtaken and overwhelmed by a violent storm, destroying or damaging their ships. They were convinced that they saw the witch herself seated on the prow of the Jarl's ships with clouds of missile weapons flying from the tips of her fingers, each arrow carrying a death-wound. With such of his followers as had escaped the sorceric encounter, the pirate-chief made the best of his way from the scene of destruction, declaring he had made a vow indeed to fight against men, but not against witches. A narrative not inconsistent with the reply of a warrior to an inquiry from the Saint-king Olaf, 'I am neither Christian nor pagan; my companions and I have no other religion than a just confidence in our strength, and in the good success which always attends us in war; and we are of opinion that it is all that is necessary.'--Mallet's _Northern Antiquities_.
