China, 550-577. Finely carved with almost perfectly symmetrical features imparting the head with a serene vitality, the eyebrows rising in smooth curves issuing from the bridge of the nose, the deeply-set large eyes half-closed under heavy lids sweeping in bowstring curves, the crisp undulating lips forming a subtle smile, all flanked by large ears with deeply cut lobing, beneath stylized hair depicted as undulating and overlapping waves rising rhythmically up to the smoothly domed ushnisha and centered with two whorls.
