BACKGROUND AND OBJECTIVES: Manuscripts are the unknown treasures and cultural reserves of any nations, which the main tasks of researchers and scholars are to try to identify and study these works. One of these enduring heritags is the historical-religious epic of Delgoshanameh, which was composed by Mirza Arjmand Azad Kashmiri, on the subject of Mukhtar Uprising in the first half of the twelfth century A. H. in Motagareb rhythm in 15450 verses. In this article, we have introduced the work and studied the stylistic style of Delgoshanameh from the linguistic, literary and intellectual perspectives. METHODOLOGY: The present research is a theoretical study that has been done by library method and descriptive-analytical method. The study area and population is a manuscript of Delgoshanameh that is available in libraries in Iran and the world. FINDINGS: The content of this work has the characteristics of Khorasani style such as: old words and compounds, the use of verbs in the ancient form, the use of literary arrays, singular and sensory similes, understandable allusions, and so on. With initiative and innovation in using novel and expressive techniques, having some relatively original linguistic and literary features and extensive use of epic words and combinations, the poet has been able to use linguistic possibilities in the service of religious ideas and the subject of epic work. CONCLUSION: The results of the research show that 《 Azad》 has shown with great taste in composing this work and has been successful in following the poets of her predecessors, especially Ferdowsi, Saadi and Nezami. The choice of Motagareb rhthym in this work, due to the many long syllables and ending in the culprit, has brought it closer to the epic language style. The description of battlefield heroes, imaginative exaggerations, and transcendence of habits and virtues is quite evident in this poem. Bringing of Saghi letters and legal and lyrical terms has caused the combination of Ghanaian or epic language in parts of this poem.
