Frode left three sons, Halfdan, Ro, and Skat, who were equal in valour, and were seized with an equal desire for the throne. All thought of sway, none was constrained by brotherly regard: for love of others forsaketh him who is eaten up with love of self, nor can any man take thought at once for his own advancement and for his friendship with others. Halfdan, the eldest son, disgraced his birth with the sin of slaying his brethren, winning his kingdom by the murder of his kin; and, to complete his display of cruelty, arrested their adherents, first confining them in bonds, and presently hanging them. The most notable thing in the fortunes of Halfdan was this, that though he devoted every instant of his life to the practice of cruel deeds, yet he died of old age, and not by the steel. Halfdan's sons were Ro and Helge. Ro is said to have been the founder of Roskild, which was later increased in population and enhanced in power by Sweyn, who was famous for the surname Forkbeard. Ro was short and spare, while Helge was rather tall of stature. Dividing the realm with his brother, Helge was allotted the domain of the sea; and attacking Skalk, the King of Sklavia, with his naval force, he slew him. Having reduced Sklavia into a province, he scoured the various arms of the sea in a wandering voyage. Savage of temper as Helge was, his cruelty was not greater than his lust. For he was so immoderately prone to love, that it was doubtful whether the heat of his tyranny or of his concupiscence was the greater. In Thorey he ravished the maiden Thora, who bore a daughter, to whom she afterwards gave the name of Urse. Then he conquered in battle, before the town of Stad, the son of Syrik, King of Saxony, Hunding, whom he challenged, attacked, and slew in duel. For this he was called Hunding's-Bane, and by that name gained glory of his victory. He took Jutland out of the power of the Saxons, and entrusted its management to his generals, Heske, Eyr, and Ler. In Saxony he enacted that the slaughter of a freedman and of a noble should be visited with the same punishment; as though he wished it to be clearly known that all the households of the Teutons were held in equal slavery, and that the freedom of all was tainted and savoured equally of dishonour.
