Yi Xing

Yi Xing, born in the year six hundred eighty-three, was a prominent Buddhist monk during the Tang dynasty, celebrated for his remarkable contributions to both astronomy and mathematics. His expertise extended to the reform of the imperial calendar, where he implemented significant changes that would influence timekeeping practices in China. Yi Xing's innovative spirit also led to the creation of a celestial globe equipped with a liquid-driven escapement, marking a pivotal moment in the evolution of Chinese astronomical clockworks.

In addition to his secular achievements, Yi Xing was a revered figure within Buddhist circles. He is particularly noted for his work on the Mahāvairocana-sūtra, where he not only contributed to its translation but also authored the authoritative commentary known as the Darijing shu. His deep understanding of Esoteric Buddhism further solidified his status as a distinguished scholar and practitioner.

As a result of his dual impact on religious and secular domains, Yi Xing became the subject of legendary tales during the late Tang period. He was often portrayed as a master astrologer and a practitioner of astral magic, with several astrological works attributed to him. This blend of spirituality and scientific inquiry exemplifies the rich tapestry of his life and the lasting legacy he left behind.
