A breezy compilation of light fantasy stories emerges from a usually heavy-handed spiritual seeker. In comparison to Hesse's other works, most of these tales seem underdeveloped (quite possibly on purpose). I concur with Hesse (and numerous others) regarding the cultural importance of fairy/folk tales. However, it's challenging to create short versions that don't come across as trivial.
The standouts are the quietly potent Jesus-like allegory "Hannes," "The Painter," "Bird," and "Two Children's Stories." I also closely related to the first of his "Nocturnal Games," as it's an anxiety dream I've experienced multiple times myself. What many of the finest stories in the collection share is their strong autobiographical nature. "Two Children's Stories" specifically provides captivating insights into Hesse's personal life and thought process. "Bird" is perhaps the most complete story, incorporating references to various other stories and works like "Klingsor's Last Summer," "Pictor's Metamorphoses," and Journey to the East. This, along with biting social satire.
Another aspect I appreciated about the collection is that it chronicles Hesse's growth as an author, as the stories are presented in chronological order, with some dating back even before his adulthood. His evolution is intriguing to dedicated fans like me.
Overall, I would recommend this collection solely to Hesse aficionados. A superior, more refined collection of stories, some of which are also fantastical, would be Strange News from Another Star (see my review). This is where I would begin if you're interested in Hesse's short works.
