The Characteristics of Ancient China’s Astronomy
Published online by Cambridge University Press: 12 April 2016
Extract
What are the characteristics of ancient China’s astronomy? Many scholars have discussed the problem. In 1939 Herbert Chatley summed up fifteen points. Joseph Needham(1959) in his great work Science and civilisation in China concentrated it into seven points.
1 the elaboration of a polar and equatorial system strikingly different from that of the Hellenistic peoples;
2 the early conception of an infinite universe, with the stars as bodies floating in empty space;
3 the development of quantitative positional astronomy and star catalogues two centuries before any other civilisation of which comparable works have come down to us;
4 the use in these catalogues of equatorial coordinates, and a faithfulness to them extending over two millennia;
5 the elaboration, in steadily increasing complexity, of astronomical instruments, culminating in the 13th century invention of the equatorial mounting, as an ‘adapted torquetum’ or ‘dissected’ armillary sphere;
6 the invention of the clock drive for that forerunner of the telescope, the sighting tube, and a number of ingenious mechanical devices ancillary to astronomical instruments;
7 the maintenance, for longer continuous periods than any other civilisation, of accurate records of celestial phenomena, such as eclipses, comets, Sunspots, etc.
