In the framework of stylistic discourse analysis, literature is a container to express ideas and concepts which are not only relevant to their creator, but also they are in connection with the context in which the text is produced. Yet, literature is the product of discourse where it is developed and all factors like environment, context, cultural issues and dominant ideology of the period in which the specific text is generated affect the growth and visibility of it. In Persian literature, Khorasani style is the product of discourse that its dominant face is full of philosophical thoughts and particularly rationality. This period is influenced by rational thoughts and intellectuality and NaserKhosro's poems, as one of well- known and effective poets and one of the most noticeable representatives of 5th century literature, is regarded as a dominant sample of this conceptual indicators. Notable point in his poems is the influence of philosophical and religious thoughts, so that a large part of his odes court was devoted to this subject matter.

In this study, based on stylistic layer analysis, in order to specify appearance of dominant- intellectual and cultural discourse of the period in the light of lexical and syntactic style, two layers of vocabulary and syntax of a number of his ode's court are analyzed.
