“ The production of Mäster Olof marked the beginning of the new movement in Swedish literature, and the Red Room and the collection of satirical sketches entitled Del nya riket (“The New Kingdom,” 1882) increased the growing hostility to Strindberg. Two comedies drawn from medieval subjects, Gillets hemlighet (“The Secret of the Guild,” 1880) and herr Bengt's Hustru (“Bengt's Wife,” 1882) , were followed by the legendary drama of Lycko Pers resa (“The Journal of Lucky Peter”) , written in 1882 and produced with great success on the stage a year later. ”
