Besides playing an important and constructive role in the formation of this great epic, the narrations and stories in Ferdowsi’s Shah Nameh are also of great importance in terms of their narrative aspects considering the structuralistic criticism. Binary opposition is the most essential concept of structuralism, particularly narratologist structuralism, and, because such an splendid epic as Ferdowsi’s Shah Nameh is a set of oppositions in its essence, the present study authors take advantage of a descriptive method to analyze the content of Kaikhosrow’s story thereby to investigate the story’s structure based on the binary oppositions’ theory; it was figured out according to the storytelling nature of Shah Nameh that hatred and vengeance in this tory have been transformed into a narration deploying every element of the story before the other. These confrontations were studied in two lexical and narrative areas and it was made clear that the opposition between Kaikhosrow and Afrasiab for revenging the blood of Siavash, Kaikhosrow’s father, is more accentuated in the narration and words of the story and this is per se a cause of the formation of more contrasts between Turan and Iran and the confrontations of the heroes of the two foresaid countries’ heroes. These oppositions exert a considerable effect on the narrative process of the story and construction of the events and behavior of the characters amongst which the confrontation between such characters as Rostam and Piran and murdering of Forud and Kaikhosrow’s final way of treating Afrasiab and others can be pointed out that serve the advancing of the narration and application of the words in such a way that the effect of the binary oppositions on the story’s narrative level was found more prevalent than on the lexical level.
