Garment hooks of all different types and sizes were made in the late Eastern Zhou period, but hooks of this large size, richness of materials and complexity of design must have been very costly and could have been afforded only by the most privileged. A comparable example was included in the exhibition, Inlaid bronze and related material from pre-Tang China, 11 June - 5 July 1991, no. 48 and now in the Miho Museum, Japan, illustrated in the Catalogue of the collection, 1997, pp. 190-191, no. 91, where it is noted that ornate belt hooks of this type were 'a product of the late fourth-third century B.C.', and that by the end of the century they were out of fashion and no longer found in later burials. See, also, the similar example in the Wellington Wang Collection illustrated on the cover of the catalogue of the collection, Belt Ornaments Through The Ages. The most famous example of this type, fashioned from gilt silver and with a jade hook, was excavated in 1950 from tomb number 5 at Guweicun, Hui Xian, Henan province, and is illustrated by Akiyama, et al., Arts of China: Recent Discoveries, Tokyo, 1968, p. 26, pl. 17.
