This bust is after the celebrated Furietti centaur, now in the Murei Capitolini in Rome. Discovered by Monsignor Furietti at Hadrian's Villa, Tivoli in 1736, this celebrated antiquity was amongst the earliest to be engraved (in 1738 and 1739) and was, consequently, hotly pursued by the English Grand Tourists before its acquisition in 1765 at a cost of 13,000 scudi by Pope Clement XIII. Shortly following its arrival in the Musei Capitolini, Cavacceppi proceeded to supply both casts and reductions in marble and bronze, amongst the earliest of which were those acquired by Nollekens for Shugborough Hall, Staffordshire (see: F. Haskell and N. Penny, Taste and the Antique, London, 1981, pp. 177-179)
