Jing Fang (京房) (78–37 BC), born Li Fang (李房), courtesy name Junming (君明), was a Chinese music theorist, mathematician and astronomer born in present-day Puyang, Henan during the Han dynasty (202 BC – 220 AD). Although better known for his work in musical measurements, he also accurately described the basic mechanics of lunar and solar eclipses.
