Farnese Bull, sculptured group representing Zethus and Amphion, sons of Antiope, tying Dirce (who had ill-treated their mother) to an enraged bull. The sculpture is generally considered to have been executed by Apollonius of Tralles and his brother Tauriscus in the 1st or 2d cent. B.C. A copy made in the early 3d cent. A.D. decorated the Baths of Caracalla. This copy, with incorrect restorations, was later in the Farnese Palace and is now in the National Museum, Naples.
