[234] Jomsberg was the head quarters of an order of vikings or pirates, where a castle was also built by King Harold Blaatand, of Denmark. It was situated on one of the outlets of the Oder, on the coast of Pomerania. It was probably identical with Julian, founded by the Wends, and was recognized as the island of Wallin, which Adam of Bremen, in the eleventh century, described as the largest and most flourishing commercial city in Europe. Burislaus, king of the Wends, surrendered the neighboring territory into the hands of Palnatoki, a great chief of Fionia, who was pledged to his support. Accordingly he built a stronghold here, and organized a band of pirates, _commonly_ called vikings, though it must be observed, that while every viking was a pirate, every pirate was not a viking. Only those pirates of princely blood, were properly called vikings, or sea-kings. The Jomsvikings were distinguished for their rare courage, and for the fearlessness with which they faced death. They were governed by strict laws, and hedged about by exact requirements, and were also, it is said, pledged to celibacy. Jomsberg was destroyed about the year 1175, by Waldemar the Great, of Denmark, aided by the princes of Germany and the king of Barbarrossa. Those of the pirates who survived, escaped to a place near the mouth of the Elbe, where a few years after, they were annihilated by the Danes, who in the reign of Canute VI, completely destroyed their stronghold. Accounts of their achievements may be found in the Saga of King Olaf Tryggvesson, in vol. I, of Laing's _Heimskringla_. The Icelanders sometimes joined the Norway pirates, as was the case with Biörn, but they did not fit out pirate ships. Palnatoki died in the year 993. [235] Styrbiörn, son of King Olaf, ruled Sweden in connection with Eric, called the Victorious. Styrbiörn's ambition, to which was added the crime of murder, led to his disgrace. He joined the vikings, adding sixty ships to their force. He was killed, as stated, in 984, in a battle with his uncle near Upsula. [236] Dasent says in describing the coast: "Now we near the stupendous crags of Hofdabrekka, Headbrink, where the mountains almost stride into the main." [237] Referring to the dead man's blood. [238] In Iceland the women are accustomed to bring travelers dry clothes. [239] All of these verses are extremely obscure and elliptical, though far more intelligible to the modern mind than the compositions which belonged to a still older period. All the chief men of Iceland practiced the composition of verse. Chaucer makes his Parson apologize for his inability to imitate the practice. [240] See the Saga of Burnt Nial. [241] These sledges were used in drawing hay, as the roads were then, as now, too poor for carts. [242] This is the only paragraph which applies directly to the subject in hand. The following narrative will bring Biörn to notice again.
