Because the tale of Chanticleer and the Fox enters into several mediaeval narrative masterworks, there has been considerable investigation into the question of its origin. It has also been asserted that the tale has developed out of the basic situation in Aesop's fable of The Fox and the Crow. Early examples of the story are pithily fabular but towards the middle of the 12th century it appears as an extended episode of the "Reynard cycle" under the title "How Renart captured Chanticleer the cock" ("Si comme Renart prist Chanticler le Coq"). The work of which it was part was immensely popular and spread widely in translation.
