Comparative Comparative literature or in other words; the comprehensive literature of nations, using the tools and prerequisites called world literature, to study, review, compare and finally discover relationships, influence and effects, similarities, as well as to the category, It deals with the essence and independent (immanence) and simultaneous emergence of literary works.

Since the origin and content of public literature and oral literature is the emergence and manifestation of the collective unconscious mind of mankind and its history is much further than written narration, similar examples can be found in the literary works of the world that are related to each other. Of course, it is not easy to show the type and quality of dependence. The purpose of this research, which has been carried out using a documentary-descriptive method and with content analysis, is to show the influence and effects and kinship of orange and bergamot (citron) girls from famous Iranian tales with the singing bone in fairy tales from the Grimm brothers' collection in the popular literature of Germany. By studying and investigating, various results were obtained that indicate many commonalities in these two texts, and Finally, considering that Iran is the origin and source of many stories and has also been the place of passage and transition of stories from the East (India, China, Egypt, etc.) to the West it is possible to accept the options of adapting, influencing and re-creating the German legend from the Iranian and Eastern tale in the context of comparative literature studies.
