Story attractiveness is one of the popular elements of Ferdowsi 's Shahnameh. The popularity of this work has led to more interest in the publishing and motivation for bonding it with the arts. The fine specimens and the relation between art and Shahnameh can be found in illustrations of court copies. the painters of these manuscripts don't rely only on the content of story and Ferdowsi's narration, and they have been influenced by some instances such as adjoint verses, folklore, tradition of painting and side sources . A sample of this kind of influence was found in the illustrations of the Baysonghor`s version. in this article we are looking for the side factors that have illustrated the illustrated works in this manuscript. The hypothesis was that this factor is a point dependent on the text or people 's perception of Shahnameh. in order to analyze the four important paintings of this manuscript and relying on textual elements and visual signs related to Herat school, we determined the factors influencing the drawing and found that: among these cases, the attached verses have the influence on the illustrations of this manuscript. These verses, having a number of elements, such as a more detailed explanation of the narrative description, provide the possibility of more attractive. However, drawing the illustrations of shahnameh based on the attached verses, adds to their attractiveness, because of lack of integration with the original narration, it creates contradictions with the context of Shahnameh.
