Which Tolkien work was published in 1949 as a humorous medieval-style story about a farmer?

Farmer Giles of Ham was published in 1949 as Tolkien’s humorous medieval-style story about a farmer.

The book was published by George Allen & Unwin and illustrated by Pauline Diana Baynes. Its protagonist, Ægidius Ahenobarbus Julius Agricola de Ham, is an ordinary farmer whose accidental encounter with a giant leads to unexpected fame and further trouble.

Tolkien presents the story as a mock medieval chronicle, using grand names, comic misunderstandings, and a playful tone. The work is much shorter and lighter than The Lord of the Rings, but it demonstrates Tolkien’s interest in invented histories, old-fashioned language, and the relationship between legend and ordinary life.

It is often confused with Leaf by Niggle or Smith of Wootton Major, two other short works by Tolkien. Those stories explore different themes and were published in different contexts; neither centers on farmer Giles and his dragon-related adventure.
