Cocoon jars or Cocoon-shaped jars are Chinese funerary pottery vessels, belonging to the period of the 1st millennium BCE.[1] The shape is similar to the Cypriot Barrel-shaped jugs, as is generally the decoration, with vertical bands across the breadth of the vessels. The earliest type of cocoon-form jar in China dates to the Western Zhou period (99-771 BCE), either in ceramic or in bronze. The Qin dynasty period has many of them, particularly in relation with the Mausoleum of the First Emperor.[1] It has been suggested that the Chinese obtained this design from nomadic people, especially the Rong and Di cultures, through the medium of the steppes of Central Asia.[2]
