Measurement: Height 7.7 cm, Width 5.6 cm, Thickness 0.5 cm

Provenance: Unearthed from the Tomb M1 of the Chu state cemetery at Xiasi, Xichuan county, 1978.

With a colour tone caught between brown and yellow, its shape is roughly rectangular. The comb has been inscribed on both sides with thunder patterns, and it has 18 teeth, though 6 of them are broken. Two jade hairpins were unearthed from the same tomb.

With a larger burial chamber and laying side by side with the No.2 tomb in the north-south direction, the No.1 tomb yielded less burial bronzes than No.2, and no weapons and chariots were discovered, though more ornaments for women were found here than in the No.2 tomb. Inscriptions on the bronzes suggest that the tomb occupant is a lady nee Ji, the wife of Wang Zi Wu (Prince Wu), the tomb occupant of the No.2 tomb.

Bone combs were discovered dating from the early days of the Dawenkou Culture about 6000 years ago. Since then, each era has its own characteristics in the following periods. The Spring and Autumn and Warring States periods witnessed a period of rapid development of combs. During this period, the shapes and patterns began to vary with diverse purposes such as practical use, rituals, and adornments. The present jade comb is just a very representative one among them.
