1042–1047. [Sidenote: 1042 to 1044.] On the arrival of this prince in Denmark, he was received with open arms. He was the son of a saint, with whose miracles the North resounded; and his own virtues (much less questionable than his father’s) justified the expectation of a happy reign. To few princes, indeed, can history accord more virtues than to Magnus; yet he was not deficient in the active duties of his station. The Jomsberg pirates who had revolted, and whose ferocity was the dread of the North, he speedily reduced, and their capital he laid in ashes. This was a service both to the Danes and the Norwegians for which they could not be too grateful. But the former, influenced by fickleness or by attachment to their old line of kings, or by mortification at receiving a sovereign from a country which they had twice conquered, soon cast their eyes on Sweyn, son of Jarl Ulfo and of Estrida, sister of Canute the Great. After his father’s murder[138], this prince sought refuge at the court of the Swedish king. As he approached man’s estate, he grew weary of inactivity, and having something to hope from the generosity of Magnus, he repaired to that monarch in Norway. He did not ask for any portion of Canute’s vast possessions: he wanted employment merely under so generous a monarch; and his request was immediately granted. His talents, his lofty mien, his deportment, and, above all, his skilful flattery, won the confidence of the Norwegian, who made him first minister, and next his lieutenant in Denmark. There was much imprudence in confiding to one so ambitious and so nearly connected with the throne a trust of this nature; but judging of other men’s hearts by his own, Magnus thought that such a trust would for ever bind Sweyn to his interests, and be agreeable to the Danes. On the relics of St. Olaf the young prince swore fidelity to the monarch, and was well received by the people. To deepen this favourable sentiment was his constant care; and by his affability, his attention to his duties, and his liberalities, he completely succeeded. When secure of their affection, he openly revolted. Magnus assembled an armament, proceeded to Denmark, defeated and expelled the usurper, who again sought refuge at the Swedish court.
