of thought and perception of constitutionalism in the text of public law, by carefully considering the literary fields of the Constitutional Era. Therefore, the secondary goal of this study can provide the ground for a better understanding of the perceptions and views about the Constitutional Era in the Iranian constitutional legal order, to some extent, and in this respect, it is novel.This research, with an analytical-descriptive approach and using a historical approach, explores the two perspectives of poetry and prose in the Constitutional Era. Therefore, in the following article, with a pause in the concept of constitutional governance and a brief reflection on its nature, we will address the two important literary areas of the Constitutional Era (poetry and prose) that the thinkers of the period in question relied on to express their emotions and opinions.The findings of the research show that the flashes of legalism and constitutionalism, in the period before the constitutional event, were first manifested and emerged in the form of beautiful and intellectual poems based on passion and emotion, as well as in the form of plays, short treatises, statements or descriptions of memories, and each of these works was somehow effective in conveying the thoughts and mindsets of the constitutionalists. The ideas arising from the text of political and legal theories, regardless of our logic and attitude towards them, are somehow intertwined with the field of literature and the nuances and themes of Persian poetry and prose texts.
