Excavated in the baths of Caracalla in 1545 and moved to Palazzo Farnese later that year, the Farnese Bull was described as a 'marvellous mountain of marble' by Federico Zuccaro. Together with the Laocoon he regarded it as 'the most remarkable and marvellous work of the chisel of the Ancients, showing what the art of sculpture can achieve at its most excellent'. The group was much copied in bronze on a reduced scale, notably by Antonio Susini, Gianfrancesco Susini and Francesco Righetti.
