ARCHAEOLOGISTS in Qinghai Province are claiming that a 5,000-year-old stone knife marked with a constellation pattern will extend Chinas astronomy history by 1,000 years.
The finely polished stone knife, 6cm long and 3cm wide, was unearthed at the Lamao Ruins, a Neolithic site 9km west of Lamao Village in Qinghai.
Liu Baoshan, head of the Qinghai Provincial Cultural Relics and Archaeological Research Institute, said seven holes on the stone knife clearly formed the Big Dipper.
Liu said China had a long history of studying the stars.
The Collection of Ancient Texts records the world's earliest solar eclipse in 2137 BC.
There were also records of astronomical phenomena during the Xia (2100 BC1600 BC), Shang (1600 BC1100 BC) and Zhou (1100 BC221 BC) dynasties. China Daily.
