A suitable platform for the emergence of various literary movements has been provided by contemporary Persian literature, due to the socio-political events of contemporary history. The social symbolism movement is considered one of the most important of these currents. It has been realized by the poets of this contemporary movement that social adversity cannot be resisted through explicit and direct literature. This is due to the factors and obstacles by which their social lives have been made arduous, a vast portion of which is constituted by the repression resulting from the tyranny of foreign and domestic enemies. Therefore, the concepts of resistance literature must be addressed through an alternative method, namely the utilization of indirect and symbolic expression. In this study, the symbols of resistance regarding the components of tyranny and repression in the poetry of Simin Behbahani, one of the most prominent contemporary Persian poets, are examined from the perspective of Lakoff and Johnson's Conceptual Metaphor Theory. This analysis is conducted to answer the following question: "What are the symbols of tyranny and repression, and what are the metaphorical mappings of this category in the poems of this contemporary poet?" It is demonstrated by the results that 95 different symbols are utilized a total of 239 times by Simin when addressing the component of tyranny; the symbol of night, with a frequency of 39 repetitions, is identified as her most frequently used symbol for this concept. Furthermore, based on Conceptual Metaphor Theory, over 70 metaphorical mappings—such as "tyranny is night," "tyranny is winter," "tyranny is fire," and "tyranny is a whip"—can be observed in the poetry of this author.
