Dimensions: Outer diameter 12.53 cm, inner diameter 5.29 cm, thickness 0.02 cm.
Crafted in gold, the artifact is circular and extremly thin. The pattern is structured with two layers, inner and outer, both formed through precise openwork techniques. The inner layer centered on a borderless circular core, surrounded by 12 equidistant clockwise-radiating serrated rays, each ray tapering into elongated tusk profiles with sharpened terminals like a dynamic rotational solar. The outer layer features four identical birds flying counterclockwise, evenly spaced around the inner sun pattern. Each bird is depicted with an outstretched neck, extended legs, spread wings, and three-toed claws. These four divine birds head to tail, back and forth, flying counterclockwise around the sun. This artifact was crafted through multiple techniques such as hammering, cutting, and polishing, with the frontal surface polished to smooth luster and the reverse left a coarse texture. This piece of museum collections holds great historical, artistic, and scientific value, providing crucial physical evidence for studying the gold-working craftsmanship of the ancient Shu people during the Shang-Zhou dynasties, their bronze civilization, and the deeper ideological concepts embedded within their culture.
