This book, in memory of Noel M. Swerdlow, brings together new work by prominent historians of the ancient Near Eastern, Indian, Arabic, Hebrew, Classical, Hellenistic, Medieval and Renaissance traditions of astronomy, astrology, philosophy and chronology to expand our knowledge and understanding of the plurality of early sciences from Babylonia to Greece, the Greco-Roman world, India and Europe. Premodern sciences are becoming ever more important to a broader narrative of the history of science and the astronomical sciences play a particularly significant role in this history. The chapters in this work offer in-depth studies of ancient, medieval and early modern texts in the history of the astronomical sciences and related fields, such as chronology. It is unique in its range of subjects, historical periods, and primary texts, treating Babylonian Akkadian, Hebrew, Arabic, Greek and Latin sources. It represents cutting-edge research from preeminent scholars in their fields and is therefore of great interest to both historians as well as philosophers of science.
