#SilkRoad Celestial - courtesy @mhsoxford:
Unrolling & auditing a Chinese Celestial Map. This map is hand-painted silk, made in the 18th Century.
The upper planisphere shows the stars of the Northern hemisphere, the lower one those of the Southern hemisphere. The disposition of the stars is that of very ancient Chinese maps.
The constellations differ from those on Islamic and European celestial globes and star-maps. The North Pole is marked by four positions of ß Ursae minoris, forming a square which is crossed by two straight lines; around the pole there are two rows of stars, called by the Chinese the Western Hedge and the Eastern Hedge. The only constellation common to Chinese and Western uranography is the Great Bear, which the Chinese call the Bushel.
Around each planisphere are marked the twelve astrological houses and the twenty-eight mansions of the moon. PH. Billmeir Collection. Inv No. 51442.
