Shi Shen


Shi Shen was a Chinese astronomer and astrologer. He was a contemporary of Gan De born in the State of Wei, also known as the Shi Shenfu.

Observations

Shi is credited with positioning the 121 stars found in the preserved texts. Shen also made the earliest surviving deliberate sunspot observation, sometimes erroneously credited to Gan De. He assumed that these spots were eclipses that began at the center of the sun and spread outward. Although he was wrong, he recognised the spots for what they were – solar phenomena.
His works included the 8-volume The rocks of Space, the one-volume Celestial Map and the one-volume Star Catalogue of Shi. The latter two are now believed to be written by his school followers. Most of his works did not survive intact, but a few of his crucial writings were preserved in the Treatise on Astrology of the Kaiyuan Era.

Books

Shi Shen wrote the Astronomy, later known as Shi's Classic of Stars.

Influence

and Shi Shen are widely quoted across a number of astronomical texts after their time, though they should not be confused with other books sharing similar names that were not written by them. One example is the Star Manual of the Masters Gan and Shi, which was actually compiled by Ma Xian circa 579 AD as an appendix to a calendar treatise.
The crater Shi Shen on the Moon is named after him.
