Although this form is familiar in painted grey pottery, it is rare to find an example in bronze. Of the few published, none has the same type of feather-like scroll decoration, but rather bands of small tightly coiled scrolls. A fu of this latter type is illustrated by Gisèle Croës in her catalogue for an exhibitin in Maastricht, March 1997, pp. 48-9, and another was sold in these rooms, 21 March 2002, lot 68. There are variations in the number and width of the plain bands on these two, as well as the arrangement of the taotie mask and ring handles.
According to Ma Cheng Yuan, during the Spring and Autumn period the hu develops into a vessel with an egg-shaped body and a short contracted neck, and that "this new form was very popular". See Ancient Chinese Bronzes, Hong Kong, pp. 197-8.
