The Iron Stove (Der Eisenofen) is a fairy tale collected by the Brothers Grimm, as tale number 127. It is Aarne–Thompson type 425A, the animal bridegroom. Dorothea Viehmann prepared the story for the Grimms' collection. Synopsis A prince is cursed by a witch and imprisoned in an iron stove in the woods. A lost princess finds the stove and is surprised to find it talking to her, offering to help her find her way back home, provided she return to the woods with a knife to scrape a hole in the stove, thereby freeing the prince, and marry him.
