This is a madcap story about a tract of land which is topologically folded through a shamanic incantation. Contains descriptions of some physical effects but explicitly states that the topological defect exists only in the human mind (photographs of the area show no anomaly). It should be compared to Baxter's "A Pacific Mystery", which talks about a similar topological curiosity, albeit one that is physical in nature. Might also be comparable superficially to Priest's 'Inverted World'. It is an enjoyable tall-tale if you leave your grain of salt aside.

I'm not really sure that this story is sufficiently mathematical to be listed on this website. Though it does mention the words "topological" and "dimension", the described phenomenon is more a combination of strangeness and the supernatural than mathematical. Still, as Vijay points out, it makes a good comparison for the (more mathematical) Inverted World and A Pacific Mystery.

First appeared in The Magazine of Fantasy and Science Fiction, September 1966.

Where are the new works of mathematical fiction?: As you can see from this chronological listing, this database includes many works of mathematical fiction for each year from 1990 to 2025. Strangely, only two are listed for 2026, so far. Either less mathematical fiction is being published than in previous years or I'm just having more trouble finding it. If you know of any works of fiction that should be added to this list, especially recently published ones, please let me know. (Keep in mind that I do not include self-published works or children's fiction that just covers elementary mathematical concepts.) Thanks!
