A horse statue from the Sung dynasty.
The Sung dynasty ruled China for over three hundred years until the thirteenth century when it fell to the grandson of Genghis Khan.
During a mission to Ligon II, Captain Picard presented its leader, Lutan, with a statue of a horse created during the Sung dynasty. He misidentified it as originating in the fourteenth century, but was corrected by Data. (TNG: "Code of Honor")
