The first ode in Farrokhi Sistani’s Divan is a poetic description of clouds. It has been imitated by many poets. The authors of the present research have studied the first part of the ode (Taqazzol), which has been imitated by three poets close to Farrokhi’s time- Azraqi, Masoud Sa’d, Amirmo’ezy- comparing them with Farrokhi’s own poem, in the framework of systemic–functional linguistics. Since Azraqi is known for his poetic innovations and Amirmo’ezy is accused of sheer imitation – if not literary theft – of Farrokhi’s Divan and Onsory’s, the research can also provide a scientific and objective analysis of creativity, innovation or sheer imitation. No doubt many literary artistic beauties and fine points cannot be explained through linguistic analysis. However, most linguistic approaches, methods, and tools are useful for understanding literary texts preventing subjective evaluations and judgments.
