In his later work, Ibsen moved away from realistic drama to tackle questions of a psychological and subconscious nature. Accordingly, symbols began to gain prominence in his plays. Among the works he wrote in this symbolist period are The Wild Duck (1884) and Hedda Gabler (1890). Hedda Gabler was the last play Ibsen wrote while living abroad. In 1891, he returned to Oslo. His later dramas include The Master Builder (1892) and Little Eyolf (1896). Eventually, a crippling sickness afflicted Ibsen and prevented him from writing. He died on May 23, 1906.
