A good example of stone sculpture is the well-known erect Buddha from Sarnath. Of the Brahmanical images the most impressive is the Great Boar at the entrance of a cave at Udayagiri. The art of casting statues on a large scale by the cire process was practised by Gupta craftsmen with conspicuous success. Two outstanding examples metal sculpture are copper image of the Buddha about eighteen feet high at Nalanda in Bihar and Sultanganj Buddha of seven and half feet.
