Abstract

The Chinese monk Yixing 一行 (673–727) is unique in being an early architect of the Mantrayāna tradition (Esoteric Buddhism) in East Asia in addition to featuring as a significant individual within the history of astronomy and calendrical science in China. His legacy in the Buddhist world is well known, but the enduring appreciation of his scientific work in later centuries is less understood. The present paper will document the achievements of Yixing’s work in astronomy while also discussing the perception and appreciation of his work in subsequent centuries.
