This article examines Mīr ʿAlī Shīr Navāʾī's Sabʿa-yi Sayyār (889/1484), a Chaghatay rewriting of Niẓāmī's Haft Paykar and Amīr Khusraw Dihlavī's Hasht Bihisht. In the prologue of his masnavī, the Timurid poet expresses harsh criticism against his Persian models. He targets his predecessors’ frame stories, and more specifically their depiction of Bahrām Gūr's behavior while listening to the seven nested narratives. In fact, Navāʾī's reshaping of the poem epitomizes several Timurid trends with regard to the Persianate cultural complex: a tendency toward standardization, as well as a keen interest in Naqshbandī Sufism. Incidentally, the latter aspect shows Jāmī's influence on the Chaghatay polymath's literary output.
