Some 150 French fabliaux are extant, the number depending on how narrowly "fabliau" is defined. Filomena's humorous tale probably derives from an earlier French fabliau. Chaucer borrowed from the same fabliau as Boccaccio did. The Merchant's Tale is like a Fabliau. Emilia's tale originates from the fabliau "Le Prestre et Alison" by Guillaume Le Normand. It resembles an earlier French "fabliau" by Pierre Anfons called "Le revenant". Additionally, the medieval church also found use for the fabliau form. There are two versions of the fabliau&colon; one by Guerin and one anonymous. This tale (and the next one) comes from a 13th-century French fabliau by Eustache d'Amiens. A comparable "trope" that Diderot must have known is found in the ribald "fabliau". One question that splits critics is whether the Merchant's tale is a fabliau. "Fabliau of Florida" is a poem in Wallace Stevens's first book of poetry, "Harmonium".
