Observation of Solar and Lunar Eclipses |
As the legend goes, Ji Dan, also called Duke Zhou, a politician in the early Western Zhou Dynasty, was accomplished in producing ritual music pieces, establishing institutions and calendar issues. Once he set up a platform for observing shadows cast by the sun in Yancheng (today's Gaocheng Town, Dengfeng County, Henan). He measured the four solar terms of midwinter, spring begins, summer solstice and autumn begins through the changing shadows. It is also the earliest and best-preserved astronomical site in China. |
