Yixing (Chinese: 一行; pinyin: Yīxíng; Wade–Giles: I-Hsing, 683–727) was a Buddhist monk of the Tang dynasty, recognized for his accomplishments as an astronomer, a reformer of the calendar system, a specialist in the Yijing (易經), and a distinguished Buddhist figure with expertise in Esoteric Buddhism. In the realm of secular affairs, Yixing gained prominence for his reforms to the imperial calendar and his construction of a celestial globe featuring a liquid-driven escapement, the first in a long tradition of Chinese astronomical clockworks. Within Buddhist circles, he is particularly remembered for his contributions to the translation of the Mahāvairocana-sūtra and for authoring the authoritative commentary on that scripture, the Darijing shu 大日經疏 (T 1796).
