Polychrome-enamel Porcelain Bowl with "Five Relationships" Motif Yung-cheng period (A.D. 1723-1735) Ch'ing Dynasty Height: 7.6cm Depth: 6.8cm Mouth diameter: 16.2cm Foot rim: 6.7cm Polychrome-enamel porcelains of the Yung- cheng and Ch'ien-lung periods are celebrated for their exceedingly fine workman ship and delicate ornamentation. This kind of porcelain is also referred to as Ku-yueh Hsuan, or "Ancient Moon Terrace " ware. The five pairs of birds represented on this bowl -- phoenixes, cranes, mandarin ducks, magpies, and golden orioles -- symbolize the five human relationships of the Confucian ethic: emperor to his ministers, father to son, husband to wife, elder brother to younger brother, and friend to friend. The porcelain body is extremely thin and semi-translucent.
