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.

In recent decades various versions of Chinese medicine have begun to be widely practiced in western countries, and the academic study of the subject is now well established. However, there are still few scholarly monographs that describe the history of Chinese medicine and there are none at all on the medieval period. The collection presented here is an example of the kind of international collaboration of research teams, centers and individuals that is required to begin to study the source materials adequately.
The primary sources for this research come from a collection of medieval manuscripts discovered in 1900 in a walled-up room in the Buddhist cave-shrines of Dunhuang, Gansu Province, west China. Dunhuang was formerly an important Silk Road town, and formed the base of one of the first garrisons to be established during the Han period to secure the safe passage of soldiers, officials and traders between east and west. While the majority of the manuscripts stored in the cave are copies of Buddhist scriptural texts, there are also thousands of non-Buddhist texts, both religious and secular. The presence among these of some one hundred medical texts suggests that the Dunhuang prefectural school was a centre for copying and transmitting medical writings. In the collection we find the earliest handwritten copies of well-known classical medical treatises, together with hitherto unknown medical works, including illustrations and charts, texts related to religious and popular healing traditions and, excitingly, extensive portions of texts previously known only through brief quotations in later works.
This is the first book to discuss this fascinating material in a western languagein the century since the Dunhuang library was discovered, and it is likely to remain the only book of its kind in English for a considerable time.

This is a study and translation of the Zhou bi suan jing, a Chinese work on astronomy and mathematics which reached its final form around the first century AD. The author provides the first easily accessible introduction to the developing mathematical and observational practices of ancient Chinese astronomers and shows how the generation and validation of knowledge about the heavens in Han dynasty China related closely to developments in statecraft and politics. The book will be of equal interest to historians of science and those studying the history of Chinese culture.
