A proper understanding of nonverbal communication and decoding its messages significantly impacts the comprehension of poets' poetry. In principle, it is not possible to identify a poet's poetic style, worldview, poetic art, and the literary quality of their words without interpreting their nonverbal behaviors. The present study aims to examine and analyze the epic poem Derafsh-e Kavian by Hamid Mosaddeq from the perspective of nonverbal communication and the decoding of nonverbal markers. Using a descriptive-analytical method, this research examines the types of nonverbal communication tools and the extent of Mosaddeq's use of these elements. It also seeks to evaluate the impact and function of each tool in transmitting the message, the fertility of the text, and the process of artistic transformation of the poet's words. To achieve this goal, after examining the collection, these tools were interpreted and decoded into six categories—appearance, body movements, facial behaviors, paralinguistics, artifacts, and haptics—and several subcategories, classifications, and poetic evidence, each concerning Birdwhistell's kinesics theory. The research approach indicates that Mosaddeq used appropriate nonverbal tools to depict the desperate and stifling environment of his era, to commemorate the Kaveh uprising, and to create an epic atmosphere and inspire the oppressed people toward a Kaveh-like uprising. In conveying the intended concepts and convincing the audience, Mosaddeq mostly resorted to the movement of limbs and artifacts, while appearance and haptics were less considered. These tools often had a substituting function, followed by complementing and regulating-substituting functions.
