Metaphor is one of the most important types of trope e that has a special place in every language, but the way it has been viewed in various languages is different. In Arabic and Persian, the similarities of this discussion are more than its distinctions, in that most of the metaphorical topics of Arabic rhetoric books have been repeated in Persian books two or three centuries later. The subject of metaphor in Arabic books has experienced five stages of outset, growth, prosperity, recession, and Modernism, and has undergone three stages of genesis, expansion, and edition in Farsi with fewer developments. Genesis corresponds to the period of outset and growth; the period of expansion corresponds to the period of recession and the period of edition to the period of Arab modernism. Unfortunately, the Persian rhetoric has not benefited much from the prosperity period of the Arabic rhetoric, so its analytical and aesthetic outlook is weak. Today, research in both languages tend to focus on critical topics, the use of metaphorical studies of other languages, and the linguistic outlook, with a greater emphasis on the nature of language and Nativism in Persian metaphor- seekers. Not paying attention to the development of metaphorical culture, disregard for literary types and styles in metaphorical research, and disregard for the evolution of metaphor in literary texts are the weaknesses of metaphorical research in both languages
