Ferdowsi’s Shahnameh is one of the most fundamental texts of Iranian culture, rich in symbols and imaginative structures with profound mythological and mystical potential. While these symbols have been extensively explored in fields such as miniature painting and literature, their systematic application in fashion design has received comparatively little scholarly attention. The present study aims to analyze the mystical symbols of the Shahnameh based on Gilbert Durand’s theory of the “Anthropological Structures of the Imaginary” and to translate these symbolic structures into applicable elements in fashion design.This research adopts a qualitative–analytical methodology with an interpretive approach. Data were collected through content analysis of selected sections of the Shahnameh related to mystical symbolism and were categorized according to Durand’s diurnal and nocturnal regimes of the imaginary. Subsequently, in accordance with principles of fashion design, the extracted symbolic concepts were transformed into visual elements, including line, form, color, texture, material, and motif. The resulting visual language served as the conceptual basis for designing a fashion collection centered on the theme of the “reconciliation of opposites.”The findings indicate that Shahnameh symbols such as fire, mountain, sword, and sun correspond to the diurnal regime of the imaginary, whereas symbols such as the Simurgh, water, mist, embrace, and circle align with the nocturnal regime. This classification enabled the extraction of two complementary visual logics: one rigid, angular, and ascensional, and the other soft, fluid, and encompassing
