The Dunhuang map or Dunhuang Star map is one of the first known graphical representations of stars from ancient Chinese astronomy, dated to the Tang dynasty (618–907). Before this map, much of the star information mentioned in historical Chinese texts had been questioned.[2] The map provides a graphical verification of the star observations, and are part of a series of pictures on one of the Dunhuang manuscripts. The astronomy behind the map is explained in an educational resource posted on the website of the International Dunhuang Project, where much of the research on the map has been done.[3] The Dunhuang Star map is to date the world's oldest complete preserved star atlas.[4]
The Dunhuang star atlas is one of the most spectacular documents of the history of astronomy. It is a complete representation of the Chinese sky including numerous stars and asterisms depicted in a succession of maps covering the full sky (Figure 1). Apart its aesthetic appeal, the document found on the Silk Road is remarkable as it is the oldest star atlas known today from any civilization.
