Description

The Foundations of Celestial Reckoning gives the reader direct access to the foundational documents of the tradition of calculation created by astronomers of the early Chinese empire between the late second century BCE and the third century CE. The paradigm they established was to shape East Asian thought and practice in the field of mathematical astronomy for centuries to come. It was in many ways radically different from better known traditions of astronomy in other parts of the ancient world. 

This book includes full English translations of the first three systems of mathematical astronomy adopted for use by imperial astronomical officials, together with introductory material explaining the origin and nature of each system, and a general introduction to the work as a whole. The translations, which are accompanied by the original Chinese text, give a consistent rendering of all technical terms, and include detailed explanatory notes. The text in which the second of the three systems is found also includes a unique collection of documents compiled around 178 CE by two experts in the field, one of whom was the author of the third system translated in this book. Using material transcribed from government archives of the two preceding centuries, these scholars carefully document and review controversies and large-scale official debates on astronomical matters up to their own time. Nothing equivalent in detail and clarity has survived from any other ancient culture. The availability of the totality of this material in English opens new perspectives to all historians of pre-modern astronomy.

Reviews

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).

About the Series

Scientific Writings from the Ancient and Medieval World

Scientific texts provide our main source for understanding the history of science in the ancient and medieval world. The aim of this series is to provide clear and accurate English translations of key scientific texts accompanied by up-to-date commentaries dealing with both textual and scientific aspects of the works and accessible contextual introductions setting the works within the broader history of ancient science. In doing so, the series makes these works accessible to scholars and students in a variety of disciplines including history of science, the sciences, and history (including Classics, Assyriology, East Asian Studies, Near Eastern Studies and Indology).

Texts will be included from all branches of early science including astronomy, mathematics, medicine, biology, and physics, and which are written in a range of ancient languages including Akkadian, Arabic, Chinese, Greek, Latin, and Sanskrit. Thus, the series is of use both in the teaching of history and the history of science and for researchers on ancient science. In addition, the series provides a venue for the publication of original research on early scientific texts, in particular through the commentaries.
