A fourteenth-century redaction of an earlier, now-lost text, Dānişmendnāme is a religious-heroic prosimetrum narrative well known for its themes of ġazā and confrontation with the Christian Other, but vast lacunae exist in the study of this text. Its myriad poems have never before been considered and its prose has long been denied scholarly treatment that goes beyond its obvious preoccupation with war against the infidel. This dissertation argues that Dānişmendnāme’s rich depictions of emotions distinguish this text from other examples of its genre, making it a unique representative of Old Anatolian Turkish religious-heroic prose narratives and a natural subject for the history of emotions. Dānişmendnāme combines both formulaic and novel language to elicit emotions. The use of formulaic language does not preclude it from being worthy of study; rather, the narrative’s preservation and repetition of emotion words illuminates what kinds of modes of emotional expression were valued by the redactor, ʿĀrif ʿAlī, and his emotional community in fourteenth-century eastern Anatolia. ʿĀrif ʿAlī makes explicit in his poems that he intended for Dānişmendnāme to affect the emotions of his audience in appropriate ways at specific times. He successfully achieves this through different literary devices, such as that of mirror characters, analysis of which allows us to appreciate the relative psychological and emotional sophistication of this text. An examination of ʿĀrif ʿAlī’s historical and political context allows us to speculate how Dānişmendnāme’s depiction of kingship might in fact reflect the redactor’s contemporary political context. It also reveals the importance of the emotional relationship between king and warrior, which is a central motif of the narrative. This project’s methodological approach to the study of emotions in Dānişmendnāme unearths the contours of the emotional community of ʿĀrif ʿAlī and his audience, bringing a long-overlooked historical subject to the fore. Works of popular literature, especially ġazā-oriented narratives like Dānişmendnāme, have been relegated to specific, limited roles in the study of late medieval Anatolia. By historicizing and redefining Dānişmendnāme within the literary and cultural history of the beylik period, this project sheds new light on a familiar text and proves that Old Anatolian Turkish popular literature can contribute to the nascent field of the history of emotions in medieval Islamic studies.
