Technical Observations: The bull was cast in one piece, probably by the lost-wax technique. Losses and deformations have occurred to the flat base on which it stands; otherwise the bull is largely intact, although with poorly preserved surface detail. The even blackish-brown patina appears to be modern or possibly a repatinated surface after stripping.
