Romanticism extended to different countries around the Europe in eighteenth and nineteenth century. This school not only includes European countries but also countries outside the continent like Iran. Similarly, Romanticism developed some of its features out of Iranian contemporary literature. Sohrab Sepehri, the contemporary Iranian poet, has always been at the center of Romanticism investigation in Iran. Regarding Morse Peckham's view of Romanticism, this could be inferred that Sepehri has made a voyage from the "static mechanism" to "dynamic organicims." Sepehri's change of view causing this journey was his acquaintance with the Far Eastern mysticism. Therefore, the present study aims to investigate this phase shifting by focusing on its effect on his poems.
