The motif of the lotus flower is manifested across various artistic contexts of the Achaemenid period, notably in stone reliefs and glass artifacts. The main objective of this study is to uncover the underlying unity of thought and conceptual coherence in the representation of this symbol within both formal and ritual art on the one hand, and utilitarian and decorative art on the other. The research seeks to answer the fundamental question: How is the symbolic role of the lotus flower reflected in the reliefs and glassworks of the Achaemenid era? Using a descriptive–analytical method and drawing upon documentary, field, and online sources, representative examples of artworks were examined. The findings reveal that the lotus flower, in both artistic domains, functions beyond mere ornamentation. In the reliefs, its repetitive order and structural symmetry convey notions of cosmic harmony, stability, and the legitimacy of imperial authority. Conversely, in glassware, the material’s transparency and luminosity emphasize themes of light, purity, and spiritual elevation. This semantic correspondence between contrasting media—the solidity of stone versus the delicacy of glass—attests to a unified symbolic and intellectual framework in Achaemenid art, reflecting the interconnection between political power, religious belief, and aesthetic expression. Overall, the study demonstrates that the lotus flower served as a mediatory symbol between the terrestrial and the divine realms, reinforcing an underlying conceptual unity amid the artistic diversity of the empire.The motif of the lotus flower is manifested across various artistic contexts of the Achaemenid period, notably in stone reliefs and glass artifacts.
