Which of Tolkien’s stories features the character farmer Giles of Ham?

Farmer Giles of Ham features the character farmer Giles of Ham.

Farmer Giles of Ham is a comic medieval fantasy by J.R.R. Tolkien, first published in 1949. Its full title is Farmer Giles of Ham: Aegidii Ahenobarbi Julii Agricola de Hammo, Domini de Tame, etc. The story follows Ægidius Ahenobarbus Julius Agricola, commonly called Farmer Giles, whose accidental resistance to a dragon turns him into an unlikely local hero.

The dragon is named Chrysophylax Dives, and the story plays with the conventions of heroic legend, royal authority, and scholarly Latin. Giles does not begin as a professional warrior or legendary prince. His reputation grows because circumstances force him to act, while the supposedly powerful figures around him often prove less effective.

The book is separate from Tolkien’s Middle-earth narratives. It was published together with the essay On Fairy-Stories and the short story Leaf by Niggle in the 1967 collection Tree and Leaf. That connection sometimes leads readers to mistake it for an obscure episode from The Hobbit or The Lord of the Rings.
