It is very unusual to find large Buddhist figures of this date cast in bronze, rather than carved in wood (and often gilt). The type is illustrated in Hai-Wai Yi-Chen, Chinese Art in Overseas Collections, National Palace Museum, Taibei, Buddhist Sculpture, no.133, the large Avalokitesvara from the British Museum; and ibid., no.130, the more elaborate Guanyin figure in the William Rockhill Nelson Gallery of Art
