Terry Pratchett included The Fairy Feller's Master-Stroke in his 2003 Discworld novel The Wee Free Men. Tiffany, the protagonist, finds it in a book of fairy-tales and later escapes from a dream set within the picture. In the author's note, Pratchett describes the painting and gives a brief but sympathetic summary of Dadd's personal history and struggle with mental illness.[citation needed]
