Note: While the cup mouth and lobed rim are not uncommon features of Liao ceramic wares, the slender, elongated silhouette of the present vase is particularly elegant.  The present example appears to be unique as no other identical vases have been published. Related vases include two examples, both with ridged necks, illustrated in Yuzo Sugimura, Toji taikei: Ryo no toji [Liao Dynasty Ceramics], vol. 40. Tokyo, 1974, pls 49 (white-glazed phoenix-headed) and 50 (with applied foliate motifs).
