This paper is a reading of La feria, a Juan José Arreola's novel, as an eminently dialogic, heterogeneous, carnavalesque and fragmentary text that constructs meanings at the macrostructure's level. The treatment of the themes involves the formal writing structure. For this reason it's such an interesting novel. The "feria" as a religious and pagan holiday is the principal subject of this novel; but the text is a fair too, a discursive fair that includes diverse material and spiritual spheres
