While rhinoceros horn cups carved with horses remain rare, a fine example decorated with the motif of Muwang bajuntu (Picture of the Eight Stallions of Emperor Wuwang), from the collection of Thomas Fok, is illustrated in Thomas Fok, Connoisseurship of Rhinoceros Horn Carving in China, Hong Kong, 1999, pl. 168, where it is noted that the piece is an unusual example of its kind. Another cup depicting grazing horses by a river bank and signed by the master carver You Kan (1660-1720), was sold in our New York rooms, 19th March 2007, lot 374; and a third cup with the horse motif, in the Chester Beatty Library, Dublin, is published in Jan Chapman, The Art of Rhinoceros Horn Carving in China, London, 1999, pl. 238. Compare also a cup finely carved with two horses within a lush river landscape, from the collection of Kenyon V. Painter, Cleveland, sold in our New York rooms, 18th September 2007, lot 10; and a further cup with a single large horse with its head lowered towards a scholar and drinking from a stream, sold at Christie’s London, 8th November 2011, lot 12.
