Freud's psychoanalytic theory has deeply influenced the literary works and works of art, and gave rise to psychological criticism. Personal unconscious and structure of mind theories are the most eminent results of Freudian outlook. According to these theories, the structure of mind has a tripartite structure: ego, id and super ego. Each one reflects a dimension of the human mind. In the story of Siyavash, as narrated in Shahnameh, the prominent characters are the representative of the tripartite; Sudabeh as the symbol of id, Siyavash as the super ego and Kavus as the ego. Action and reaction each one of them explains the structure of human mind. In the same way, and from another perspective, Afrasiab, king of Turan, can be seen as symbol of ego, Garsivaz, the brother of Afrasiab, as the symbol of id and Siyavash as the symbol of super ego. Based on such an analysis, the present article reconsiders the story of Siyavash.
