This is the first investigation of one of the main interests of astronomy in Islamic civilization, namely, timekeeping by the sun and stars and the regulation of the astronomically-defined times of Muslim prayer. The study is based on over 500 medieval astronomical manuscripts first identified by the author, now preserved in libraries all over the world and originally from the entire Islamic world from the Maghrib to Central Asia and the Yemen. The materials presented provide new insights into the early development of the prayer ritual in Islam. They also call into question the popular notion that religion could not inspire serious scientific activity. Only one of the hundreds of astronomical tables discussed here was known in medieval Europe, which is one reason why the entire corpus has remained unknown until the present. A second volume, also to be published by Brill, deals with astronomical instruments for timekeeping and other computing devices.

Up until the end of the eighteenth century, the way Ottomans used their clocks conformed to the inner logic of their own temporal culture. However, this began to change rather dramatically during the nineteenth century, as the Ottoman Empire was increasingly assimilated into the European-dominated global economy and the project of modern state building began to gather momentum. In Reading Clocks, Alla Turca, Avner Wishnitzer unravels the complexity of Ottoman temporal culture and for the first time tells the story of its transformation. He explains that in their attempt to attain better surveillance capabilities and higher levels of regularity and efficiency, various organs of the reforming Ottoman state developed elaborate temporal constructs in which clocks played an increasingly important role. As the reform movement spread beyond the government apparatus, emerging groups of officers, bureaucrats, and urban professionals incorporated novel time-related ideas, values, and behaviors into their self-consciously “modern” outlook and lifestyle. Acculturated in the highly regimented environment of schools and barracks, they came to identify efficiency and temporal regularity with progress and the former temporal patterns with the old political order. Drawing on a wealth of archival and literary sources, Wishnitzer’s original and highly important work presents the shifting culture of time as an arena in which Ottoman social groups competed for legitimacy and a medium through which the very concept of modernity was defined. Reading Clocks, Alla Turca breaks new ground in the study of the Middle East and presents us with a new understanding of the relationship between time and modernity.
