The paper presents a comparative analysis of the Pahlavi “Story of Jōišt ī Friyān”, comparing it with three other tales, which span several hundred years and belong to several cultural traditions. By isolating structural and content-related features from the narrative core of these tales and setting them into relation with each other, the present author attempts to answer the following questions. Are there meaningful parallels between these four tales, which would suggest literary borrowing? And, if there are, would it be possible to identify one of them as the primary source of the others? The study is intended to contribute to our understanding of the process of literary exchange between Zoroastrians and Muslims in early Mediaeval Iran.

本文对巴列维的《约瑟夫·弗里扬故事》进行了比较分析，并将其与其他跨越数百年并属于几种文化传统的故事进行了比较。通过从这些故事的叙述核心中分离出结构和与内容相关的特征，并将它们彼此联系起来，本作者试图回答以下问题。这四个故事之间是否存在有意义的相似之处，这暗示着文学借阅？而且，如果有的话，是否有可能将其中一个作为其他来源的主要来源？该研究旨在帮助我们理解伊朗早期中世纪琐罗亚斯德教徒和穆斯林之间的文学交流过程。
