The story of Siyavash in Ferdowsi's Shahnameh is a tragedy that dramatizes the tension between moral goodness and political necessity. Drawing on Martha Nussbaum's The Fragility of Goodness: Luck and Ethics in Greek Tragedy and Philosophy (1986), this article rereads Siyavash as a symbol of "fragile goodness." By emphasizing the vulnerability of human flourishing (eudaimonia) to chance (tuchē), Nussbaum contrasts Greek tragedy and Aristotelian philosophy with Plato's attempt to render goodness invulnerable. Siyavash, through his upbringing by Rostam, his chastity in the face of Sudabeh, the ordeal of fire, his refuge in Turan, and his unjust death, embodies precisely this fragility: a hero whose moral goodness is reduced to ashes in the face of power relations and realpolitik, yet who, like a phoenix, is revived in the legacy of Kay Khosrow and in Iranian culture. Drawing on Martha Nussbaum's The Fragility of Goodness, the article shows that accepting this fragility is not a weakness, but a condition of the possibility of human ethics and resistance to violent politics.
