In this manuscript, beside a brief introduction of the poet, the stylistic features of his poems are explained at three levels of linguistic, literary and intellectual in a layered manner. By reviewing the poems, in addition to the epic themes, it appears that many of the verses are different from the epic atmosphere of the poems. Therefore, this is a martial and festive work which the existence of beautiful idols in battle scenes and even bringing SĀQI-NĀMA at the end of each topic has made this feature even more prominent. Qassemi has created a new style of saga. By carefully examining the issues and events of the stories, the authors reached the point that Shahrokh-Nameh is a combination of epic, history and lyric. Qasemi's lexical games indicate his dominance of vocabulary, metre and rhythm in poetry. Qasemi's imagery depicts his skill in imagination and meaning and to the fullest extent; it is the use of words, expressions and lyrical images to express epic adventures.
