Compare the similar double-tube vase dated Ming dynasty (16th-17th century) in the British Museum illustrated by J. Rawson, Chinese Jade from the Neolithic to the Qing, London, 1995, p. 387, fig. 5. The author relates this cup to a Han dynasty jade cup with cylindrical body on a pedestal foot (fig. 3), p. 386, and also to a gilt-bronze stand in the shape of a bird suspending a ring standing atop a remcumbent beast and flanked by two attached pedestal trays that most likely held tube-shaped cups (fig. 4), p. 387. The British Museum example is also illustrated in the catalogue of the O.C.S. exhibtion, The Arts of the Sung Dynasty, London, 16 June-23 July 1960, pl. 91, no. 276.
