The Buddha is shown here wearing a kasaya, a robe made from patches of cloth joined together. As discussed in Buddhist Images in Gilt Metal, Chang Foundation, Taipei, 1993, p. 38, kasaya in Chinese is translated as futian ('happy fields'), implying that "supporting monks is equivalent to planting fields".
A gilt-bronze figure of Sakyamuni Buddha dated 18th century and wearing very similar robes is illustrated op. cit., p. 45, no. 15. Another larger (30.2 cm. high) gilt-bronze figure of Sakyamuni with hands in bhumisparsa mudra and inscribed with a Qianlong mark around the base is illustrated in The Asian Collections, Art Gallery of New South Wales, Art Gallery of New South Wales, 2003, p. 98 (upper right). See, also, the large gilt-bronze figure (39 cm.) of Sakyamuni sold in our New York Rooms, 19 September 2006, lot 135.
