Navigating historiographical boundaries in the early Turkish Republican period: astrology, nationalism and Aydın Sayılı’s scholarship

Abstract

This article explores two aspects of Aydın Sayılı’s scholarship: his focus on astrology and the impact of nationalist sentiments on his research. Sayılı, perhaps the first globally recognized PhD-holder in history of science, completed his degree at Harvard in the early 1940s and established Turkey’s first academic chair in the field at the University of Ankara. His works addressed both international and local audiences, advancing the history of mathematics and astronomy in Islamic societies; his scholarship on Islamic observatories is still highly esteemed today. This study highlights Sayılı’s integration of astrology into discussions in the history of science, especially with respect to Islamic observatories, a significant choice in an era when astrology and related disciplines received minimal attention in Turkish historiography. While his approach to this discipline diverges from that of prevalent twentieth-century Turkish scholarship, Sayılı’s motivations were deeply intertwined with the nationalist sentiments of the early Turkish Republic, emphasizing ‘Turkish contributions to science’. His scholarship invites further examination of the intricate relationship between the historiography of science and nationalism, as well as of twentieth-century historicizations of astrological studies.
