Depicting the Buddhist Paradise. Imperial workshops located in Beijing and Canton (Guangzhou) created spectacular works of art of all types, but few as elaborate as this example. The model is composed of zitan, a wood largely restricted for Imperial use and characterized by a dense, tight grain and dark purplish-black color. The figures and pavilions are of gilt bronze with details in silver, gilt-silver, kingfisher feather, simulated malachite, coral, ivory, and enamels. It is likely this model was created as a presentation gift possibly from the Imperial household to a high official or dignitary upon an auspicious occasion. The workmanship and design indicate that this is most likely from the Guanxu reign (1875-1908), most likely in the early years of his reign. The model is complete with the original black lacquer bronze-mounted carrying case. (Estimate: $30-50,000)
