Mawangdui is a Han dynasty capital located in a suburb of modern-day Changsha in Hunan Province in China. Three rich tombs were discovered at Mawangdui, dated to the 2nd century BC. They belonged to Li Dang, the Marquis of Dai (died 186 BC); his wife Lady Dai (died after 168 BC); and their son (died 168 BC). Lady Dai's tomb was in an astonishing state of preservation. On top of Lady Dai's tomb was found this remarkable tapestry; nearly 200 silk manuscripts were also found, including seven treatises on ancient medicines.
