In the period of about a dozen years following the death of Wergeland, the life, manners and characteristics of the Norwegian people were given the especial attention of the literary writers. Prominent in this period was Peter Christian Asbjörnsen (1812-1885), who, partly alone and partly in conjunction with Bishop Jörgen Moe (1813-1882), published some valuable collections of Norwegian folk tales and fairy tales. Moe also published three little volumes of graceful and attractive poems. Among other writers of this period may be named Hans H. Schultze ("Fra Lofoten og Solör"), N. Östgaard ("En Fjeldbygd"), Harald Meltser ("Smaabilleder af Folkelivet"), M. B. Landstad (hymns), and the linguist Sophus Bugge. The efforts to bring out the national life and characteristics of the people in the literature also led to an attempt to nationalize the language in which the literature was written. The movement was the so-called "Maalstræv," and had in view the introduction of a "pure Norwegian" book-language, based upon the peasant dialects. The most prominent supporter of this movement was Ivar Aasen (1813-1898), the author of an excellent dictionary of the Norwegian language. A prominent poetical representative of this school was Aasmund Olafson Vinje (1818-1870), while Kristofer Janson (born 1841) has also written a number of stories and poems in the _Landsmaal_ (country tongue). A new and grand period in the Norwegian literature commenced about 1857, and the two most conspicuous names in this period--and in the whole Norwegian literature--are those of Henrik Ibsen and Björnstjerne Björnson.
