Jade Sculptural Composition Depicting Two Fantastic Beasts (Tianlu and Bixi). Western Han Dynasty (206 BCE – 9 CE)

This study presents a sculptural jade composition depicting two intertwined fantastic creatures, possibly tianlu (heavenly protector) and bixi (dragon-tortoise). The object demonstrates stylistic, morphological, and mineralogical features consistent with jade carving traditions of the late Zhou to early Western Han period. Detailed macroscopic and microscopic analysis reveals characteristic weathering, patination, and fibrous mineral structure typical of authentic nephrite from Khotan or Yarkand deposits. The composition should be regarded as an authentic ritual and protective artifact of high cultural significance. 🔹 DESCRIPTION - HAN-DRAG -1 Material: Natural nephrite (nephritite) with ochre and brown patinaColor: Light green with translucent areas; marginal manganese-iron weathering crustSize: [to be specified if available]Condition: Stable preservation, with partial surface erosion, micro-cavities, and soil incrustations Morphology and Artistic Treatment Form: Two zoomorphic figures with dragon-like heads. One has a carapace decorated with a hexagonal pattern (resembling tortoise shell or scaled armor), while the second creature clasps the first by the neck — a scene of symbolic interaction or protection. Ornamentation: Linear incisions (spiral scrolls, contour grooves) typical of early and middle archaic jade carving. Workmanship: Tool traces include chisel marks, percussion-abrasive shaping, deep grinding, and hand polishing. Patina: Light brown and reddish-yellow manganese-iron deposits in recesses and cavities, consistent with long-term burial in a water-alkaline soil environment. 🔹 MICROSCOPIC ANALYSIS Based on microphotographic study: Mineralization zones with secondary silicates and ochreous inclusions (likely iron hydroxides). Fibrous internal structure of translucent nephrite with intergranular cement, consistent with nephrite from Khotan or Yarkand deposits. Age-related micro-chipping of ridges and natural surface weathering confirm antiquity. 🔹 ATTRIBUTION AND DATING By stylistic features (ornament, dragon heads, carapace pattern), patination, and workmanship, the piece can be attributed with high probability to the Western Han dynasty (206 BCE – 9 CE), early phase. Alternatively, a late Zhou (5th–3rd c. BCE) provincial origin remains possible, pending further spectrometric analysis. 🔹 CONCLUSION The jade sculptural composition represents an authentic specimen of Chinese ritual and protective art from the Western Han period. The piece exhibits all diagnostic features of authenticity: archaic carving, ancient surface patina, natural aging, and hand finishing. 🔹 KEYWORDS Jade, Nephrite, Chinese art, Western Han dynasty, Late Zhou, Tianlu, Bixi, Protective symbolism, Archaeological jade, Patina analysis 🔹 REFERENCES Rawson, J.
