Sweyn showed much favour to the church. He built many places of worship, which he endowed with liberality; and he founded four new bishoprics: of these two were in Scania, viz. Lund and Dalby, which were subsequently united; and two in Jutland, viz., Wiburg and Borglum. Yet this liberality did not preserve him from quarrelling with it. His chief vice was incontinence. Numerous were his mistresses, and numerous his offspring: thirteen sons are mentioned, of whom five succeeded him[146]; but the number of his daughters was much inferior; two only appear by history. For this vice he could not hope to escape the censure of holy mother, and he married. He did not, however, marry with that mother’s consent; but chose for his queen a Swedish princess within the prohibited degrees of kindred. When Adalbert, archbishop of Bremen, heard of the union, he angrily condemned it, and by his messengers threatened the king with excommunication if he did not separate from the princess. The king resisted, and even threatened to lay Bremen (the legate’s residence) in ashes; but the power of the church was too great even for him to resist, and in the end he dismissed his wife, who had the misfortune to be his cousin. There is no reason to infer, with a recent historian of Denmark[147], that he dismissed her to recal his mistresses; for he was now arrived at an age when the empire of the passions could not be omnipotent. But he was probably taught to believe that a real was less sinful than an imaginary crime—fornication than marriage within the fourth degree.[148] [Sidenote: 1070.]
