Adolf Ivar Arwidsson, a Swedish poet, born at Padasjoki in Finland, Aug. 7, 1791, died at Viborg, June 21, 1858. He was instructed in history at the university of Abo, where he founded in 1821 the Abo Morgonblad, a literary and political journal. This enterprise was unsuccessful, as the Russian government suppressed the publication in a few months, on account of its outspoken judgments of the acts of the authorities. Soon after this Arwidsson published a political essay in the Mnemosyne, which was of such a tone as to lead to his immediate banishment. He went to Sweden, secured a position in the royal library at Stockholm, was made its chief librarian in 1843, and continued in this office till his death. In the last years of his life the Russian decree of banishment against him was annulled, and it was while taking advantage of this to revisit Finland that he died. His principal works are: Ungdoms Rimfrost ("The Hoarfrost of Youth," Stockholm, 1832), a collection of poems; an excellent collection of Swedish folk songs under the title Svenska Fornsanger ("Ancient Swedish Songs,'1 3 vols., 1834-'42); Stockholm forr och nu ("Stockholm formerly and now," 1837-'40); and a translation of the Icelandic Frithiofs Saga (2d ed., Stockholm, 1841).
