The object originates from the destroyed Lungkhar monastery in Amdo (Eastern Tibet, modern Qinghai province, China). Scientific investigation of the alloy composition using SEM–EDX confirmed the use of brass with lead inclusions, typical for Qing dynasty decorative bronzes. The vessel’s stylistic features, patination, and function are compared with documented examples from the Palace Museum (Beijing), the British Museum, and Christie's auction records. This object provides significant insight into the interaction of Tibetan monastic traditions and Qing court bronze-making practices.

Object Description Type: Ritual vessel in the form of a rhinoceros Material: Cast bronze (brass alloy, Cu–Zn–Pb) Dimensions: Length 45 cm Dating: Late 18th – early 19th century (Qing dynasty) Provenance: Lungkhar monastery, Amdo (Tibet), later via Lanzhou and Hong Kong to a private collection in San Francisco (1934). The object is cast in the shape of a rhinoceros, a rare zoomorphic form in Tibetan ritual bronzes. The body is richly decorated with swirling relief motifs, resembling stylized clouds and flames. A detachable lid, placed on the back, is ornamented with a lotus pattern. The vessel interior preserves traces of soot, indicating ritual use with oil or incense. 2. Scientific Analysis (SEM–EDX) A detailed SEM–EDX line-scan analysis across the bronze surface (512 points) revealed the following composition: Element Symbol Concentration (at. %) Error Copper Cu 38.0 0.1 Zinc Zn 24.2 0.2 Carbon C 33.6 1.5 Oxygen O 2.7 0.4 Lead Pb 1.6 0.8 The alloy is brass with lead inclusions, consistent with Qing dynasty production. Lead segregation is visible in localized inclusions, confirming deliberate addition for casting fluidity. The carbon peak corresponds to patina residues and protective coatings. The absence of tin (Sn), arsenic (As), and antimony (Sb) excludes early Chinese ritual bronzes (Shang–Zhou). 3. Comparative Study Comparable rhinoceros-shaped or animal-shaped censers and vessels can be found in: The Palace Museum, Beijing (故宫博物院): Qing dynasty animal-form bronzes, inv. no. 00253991. The British Museum: Animal-form incense burners, ca. 1800 (inv. 1995,0413.1). Christie’s, Hong Kong, 2014, Lot 1742: A gilt-bronze rhinoceros-form censer, Qing dynasty. These parallels confirm both dating and stylistic attribution. 4. Cultural Context The Lungkhar monastery, founded in the 18th century as a tantric Gelugpa branch, was abandoned in the early 20th century due to natural disasters and nomadic raids. Oral tradition recalls the rhinoceros vessel being placed in a prayer hall before a statue of Hayagriva. Its form symbolized strength and protective power, consistent with tantric iconography. The object represents a unique synthesis of Tibetan ritual practice and Qing imperial bronze craftsmanship, making it both a cultural and scientific rarity. 5. References Rawson, J.
