Keightley opens his study by tracing the fairy through Chaucer's poetry, noting that the poet's references are sparse and often satirical. In the Wife of Bath's Tale, Chaucer laments that elves no longer dance because limitours have replaced them, a sly comment on the decline of superstition. The only characteristic Keightley finds consistently attributed to popular elves is their love of dancing, as seen in the twenty-four ladies who vanish before the knight's approach. This observation sets the tone for a work that carefully sifts literary evidence for traces of folk belief.

Chaucer's Fairy References as a Starting Point

Keightley devotes several pages to Chaucer, not because the poet provides abundant fairy lore, but because his works offer a rare contemporary glimpse. In the Marchantes Tale, Pluto and Proserpina appear as king and queen of Faërie, a blending of classical and Gothic mythology that Keightley notes without elaboration. The queen's emphatic declaration "I am a woman" prompts a dry remark about the hen Pertelote using the same phrase. Keightley concludes that Chaucer gives "very little information" about popular belief, and that without the satirical passage in the Wife of Bath's Tale, one might think the poet considered the superstition extinct.

The Shifting Terminology of Elves and Fairies

Throughout the excerpts, Keightley tracks how the terms "elf" and "fairy" were used interchangeably by translators rendering Latin Nymphæ. He notes that in the Man of Lawes Tale, the word "elfe" is ambiguous, possibly meaning witch or fairy. This terminological fluidity is a recurring concern: Keightley points out that poets between Chaucer and Elizabeth's reign employed these words without specifying size or nature. The only consistent trait he identifies is dancing, a detail that recurs in multiple sources. The work thus functions as a lexical and thematic survey, mapping how language shapes belief.

Comparative Method Across European Traditions

Keightley's preface reveals his comparative ambition: the work was translated into German, praised by Jacob Grimm, and read by Goethe. He cites a letter from the orientalist Joseph von Hammer, who found the book companionable on a journey through Styria. These endorsements underscore Keightley's method of juxtaposing Scandinavian elle-maids, German elves, and British fairies. The excerpts show him moving from Chaucer to the "Maiden Reign" of Elizabeth, but the full work ranges across many countries. His approach is to collect literary and folkloric evidence, then draw cautious parallels without forcing a single theory.

The Role of Satire and Skepticism in Fairy Lore

Keightley repeatedly highlights how literary treatments of fairies are tinged with humor or disbelief. Chaucer's limitour who replaces the elf is a pointed satire of ecclesiastical hypocrisy. The queen's outburst in the Marchantes Tale is treated with wry detachment, as Keightley declines to read deeper meaning into her self-identification. This skeptical stance is part of Keightley's editorial voice: he presents the evidence, notes inconsistencies, and refrains from over-interpretation. The result is a study that respects the source material's ambiguity while still tracing patterns across centuries.

Structure and Movement Between Sources

The excerpts reveal a clear structural pattern: Keightley moves from one literary source to another, quoting brief passages and then commenting on their folkloric significance. He does not linger on any single work but builds a cumulative picture. The transition from Chaucer to Elizabethan poets is marked by a note that he does "not recollect" anything important in the intervening period—a frank admission that shapes the reader's expectations. This movement between texts, with occasional gaps acknowledged, gives the work the feel of a scholarly tour rather than an exhaustive encyclopedia.

Keightley's Fairy Mythology rewards readers who approach it as a collection of evidence rather than a unified argument. The author's willingness to note gaps and ambiguities—such as Chaucer's silence on fairy size—makes the work a reliable guide to what early sources actually say. Readers interested in the evolution of supernatural belief will find here a methodical, lightly skeptical companion that lets the texts speak for themselves.
