In 1900–1905 Spitteler wrote the powerful allegoric-epic poem, in iambic hexameters, "Olympischer Frühling" ("Olympic Spring"). This work, mixing fantastic, naturalistic, religions and mythological themes, deals with human concern towards the universe. His prose works include "Die Mädchenfeinde "("Two Little Misogynists", 1907), about his autobiographical childhood experiences, the dramatic "Conrad der Leutnant "(1898), in which he show influence from the previously opposed Naturalism, and the autobiographical novella "Imago" (1906), examining the role of the unconscious in the conflict between a creative mind and the middle-class restrictions with internal monologue.
