Christopher Cullen's expert translations and commentaries provide long-needed access to three foundational texts of Chinese astronomy, and an opening to a much wider understanding of an ancient scientific tradition comparable in richness and sophistication to that of the Mesopotamians and Greeks.- Alexander Jones, Institute for the Study of the Ancient World, New York University, USA"This book stands out as one of the notable landmarks in the progress of researching on Chinese systems. I highly recommend this important and well-written book for historians of science and all who are interested in Chinese mathematical astronomy."- Tang Quan, Xianyang Normal University, Journal for the History of Astronomy, August 2017"Cullen has provided another excellent contribution toward making Chinese astronomical texts available to a wider audience and giving the history of Chinese mathematical astronomy its well-deserved place within the general history of non-Western and premodern astronomy."- Benno van Dalen, Isis journal, March 2018"This volume will be a fundamental for the study of the history of ancient astronomy, not only Chinese, but also Arabic and, because of the transmission of Arabic astronomy to Byzantium in the late period Byzantine." - Touwaide, Byzantinische Zeitschrift issue 110 (= 2017/4).
