    • How was Ibsen's modern drama possible? 

      Fulsås, Narve; Rem, Tore (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-01-01)
      One of the major renewals in the history of drama is Henrik Ibsen’s “modern tragedy” of the 1880s and 1890s. Since Ibsen’s own time, this renewal has been seen as an achievement accomplished in spite, rather than because, of Ibsen’s Norwegian and Scandinavian contexts of origin. His origins have consistently been associated with provinciality, backwardness and restrictions to be overcome, and his ...
