Thomas Keightley

Thomas Keightley (17 October 1789 – 4 November 1872) was an Irish writer known for his works on mythology and folklore, particularly Fairy Mythology (1828), later reprinted as The World Guide to Gnomes, Fairies, Elves, and Other Little People (1978, 2000, etc.).

Keightley was as an important pioneer in the study of folklore by modern scholars in the field. He was a "comparativist" folklore collector, drawing parallels between tales and traditions across cultures. A circumspect scholar, he did not automatically assume similar tales indicated transmission, allowing for the possibility that similar tales arose independently.

At the request of the educator Thomas Arnold, he authored a series of textbooks on English, Greek, and other histories, which were adopted at Arnold's Rugby School as well as other public schools.
