This very fine image of Amoghasiddhi represents the fifth transcendental Buddha of 'Unfailing Success' and who is having the power of infallible magic. Normally the throne of Amoghasiddhi is depicted with a pair of Garuda's instead of lions. The lion is the vehicle par excellence of the central transcendental Buddha, Vairocana. The style of this image is still reminiscent to Northeast Indian, Pala, products, although the caster has added new elements more common for the thirteenth century like the shawl curling over his shoulder and the larger lotus petals of the base. Still the fine quality of the casting reminds one of the slightly earlier Pala inspired bronzes.
Compare with a Tibetan bronze figure of Amoghasiddhi dated from 12th/13th century offered in our Amsterdam Rooms, 2 May 2007, lot 302. See also a later example of a bronze figure of Amoghasiddhi from Tibet (14th century) illustrated in U. Von Schroeder, Indo-Tibetan Bronzes, Hong Kong 1981, pp.182-183, pl.35F.
