This study seeks to explore the possibility of deconstructing myths through a qualitative analysis of Haft Javidan, a novel by Marjan Fouladvand. The primary function of myth has historically been to instill certainty and belief in human beings; however, deconstruction—a strategy associated with the thought of Jacques Derrida—aims to question every form of certainty and stability. By dismantling established structures, it creates the conditions for the emergence of new systems of meaning—systems that themselves remain perpetually subject to collapse. In this novel, Fouladvand revisits the myths of Nowruz’s origins and, by drawing on their marginal signs, constructs a national epic for Nowruz that may be regarded as a deconstructive parody of earlier narratives. Through a critical reading of mythological beliefs, the novel attempts to decenter hierarchies of power and binary oppositions such as good/evil, right/wrong, and beautiful/ugly, while redefining concepts like race, lineage, heroism, and love in novel ways. Nevertheless, the findings indicate that, at a deeper level, the work reproduces the very hierarchical systems it appears to dismantle. This paradox is most evident in the representation of the Iran/Aniran opposition (i.e., Iran vs. Non-Iran) divide, where the attribution of identity privilege covertly opens the way for a return to authoritarian discourses. The study underscores that deconstruction is always at risk of turning into its own opposite and therefore requires constant revision. In this sense, deconstruction, in remaining faithful to itself, is compelled to deconstruct its own practice.
