The Jungian evaluation theory has not been fully used as a standard in analyzing the subject of the seven adventures (or Haft Khan) in Shahnameh. The main purpose of this research is to evaluate the psychological theory in the seven adventures of Rostam and of Esfandiar. By using it, we have attempted to find out the hidden aspects of the evolution of the hero’s personality in his adventures and consequently know the nature of the Jungian archetypes in the Persian epic. Therefore, the article tries to find out the relationship between the supreme Persian subject matters and Jungian theory. Moreover, the research has analyzed each of the basic Jungian elements (i.e. archetype, shadow, anima and animus, persona, etc.) in the seven adventures of Rostam and of Esfandiar, and then each of the elementary concepts in the two adventures have been decoded on the basis of the Jungian theory. It is concluded that all of the elements of the theory can be fully seen in the seven adventures of Rostam, repeatedly in some cases. The hero meets all of the Jungian archetypes in his seven adventures, and after winning them, he finally reaches the stage of individuation. On the contrary, the pattern does not have a regular order in the adventures of Esfandiar and there is no a clear reference to the archetype “Animus” in this adventure. Therefore, the seven adventures of Rostam, in comparison to that of Esfandiar, reflects the entire archetypes of Jungian theory.
