Archaic Jade Ch'i Axe Chou Dynasty (1122-221 B.C.) Length: 23.1cm Width: 14.0cm Thickness: 0.95cm The ch'i was a kind of battle-axe. Those rendered in jade were based on stone prototypes. Many were used ceremonially; others were brandished in ancient dances. Twin dragons surmount the piece, each one a hydra with a secondary beaked head. The serpents intertwine down to the tangs which are composed of two small "k'uei" dragons. The main field is dominated by a square spiral design. The cutting edge is beveled and damaged by what is thought to be a purposeful defacement. The scar reveals dark russet colors which stain the otherwise cream- white jade stone.
