Seyyed Ali Mirmosaed mainly known by his pen name, Mehri, and also known as Mehri Arab has used whatever he has seen and learned from nature and society to create the theme so that he can recreate moral and educational values and traditions of love that has always been a subject of literary texts in different images. The present study presented three groups and the methods in creating themes in Mehri Arab’s sonnets. The first group included literary terms such as line, couplet, sonnets, refrain, quintets, quatrains, ambiguity, innovation, etc. In this group, Mehri tried to present lyrical themes and concepts related to the creation and attributes of God. The second group included children’s behavior such as crying, joy, throwing stones, ignorance and so on. Mehri tried to use allegory and assign children behavior as the criteria for moral and educational concepts, and also tried to show ugliness and beauty of the audience’s behavior. The third group included elements of art such as the terms related to calligraphy. The poet used these elements to present concept and romantic themes.
