No other comparable vase appears to have been published. A similar clear green glaze and a similar solid foot showing greyish-yellow ware can be seen on a pair of tall-necked ewers with elephant-head spouts which are dated Sui based on a similar but slightly smaller example recovered in 1975 from a Sui tomb at Lehua, Xin Jian Xian, Jiangxi province, illustrated in Nan-fang Wenwu, 1994:4, p. 85 and back cover illus. 9.
The result of Oxford Authentication Ltd. thermoluminescence test no. Pl03j73 is consistent with the dating of this lot.
