Bartolomeo Cavaceppi (c. 1716 – December 9, 1799) was an Italian sculptor who worked in Rome, where he trained in the studio of the acclimatized Frenchman, Pierre-Étienne Monnot, and then in the workshop of Carlo Antonio Napolioni, a restorer of sculptures for Cardinal Alessandro Albani, who was to become a major patron of Cavaceppi, and a purveyer of antiquities and copies on his own account. The two sculptors shared a studio. Much of his work was in restoring antique Roman sculptures, making casts, copies, and fakes of antiques, fields in which he was pre-eminent and which brought him into contact with all the virtuosi: he was a close friend of and informant for Johann Joachim Winckelmann. Winckelmann's influence and Cardinal Albani's own evolving taste may have contributed to Cavaceppi's increased self-consciousness of the appropriateness of restorations — a field in which earlier sculptors had improvised broadly — evinced in his introductory essay to his Raccolta d'antiche statue, busti, teste cognite ed altre sculture antiche restaurate da Cav. Bartolomeo Cavaceppi scultore romano (3 vols., Rome 1768-72). The baroque taste in ornate restorations of antiquities had favoured finely pumiced polished surfaces, coloured marbles and mixed media, and highly speculative restorations of sometimes incongruous fragments. Only in the nineteenth century, would collectors begin for the first time to appreciate fragments of sculpture: a headless torso was not easily sold in eighteenth-century Rome.In the competition for a permanent marble of Saint Norbert for the last available niche in St. Peter's Basilica, Cavaceppi, the candidate favoured by Cardinal Albani, lost out in the end to the more conservative declamatory Baroque manner of Pietro Bracci, who received the commission.Cavaceppi, "now certainly one of the most underrated artist-personalities in that era" according to Seymour Howard, was the Pope's chief restorer, and a measure of his other clientele may be drawn from the plates that illustrated the works of art that had been restored in his extensive studio in the Raccolta, which appeared in three folio volumes, 1768-72. Haskell and Penny note that of sixty plates in the first volume, thirty-four reproduced works already belonging to Englishmen, while a further seventeen showed works in German collections. The remainder were divided among Cardinals Alessandro Albani and Giuseppe Alessandro Furietti (1684–1764) and Conte Giuseppe Fede, with one more in the Capitoline Museum and another belonging to Jacques-Laure le Tonnelier de Breteuil, the Bailli de Breteuil. The following year's volume showed sixty plates of sculptures that were all on the market. Cavaceppi made a considerable fortune from his endeavors.Cavaceppi's studio, staffed with a host of assistants, was a stop for all the young connoisseurs making the Grand Tour. Goethe described his visit in Italienische Reise XXXII. Cavaceppi was entrusted with making casts of antiquities. Joseph Nollekens purchased from Cavaceppi the casts of the Furietti Centaurs that may still be seen at Shugborough Hall, Staffordshire; Cavaceppi also produced full-size copies in marble.For his contributions in the formation of the Museo Clementino, based in large part on Albani's collection, Cavaceppi was made a Knight of the Golden Spur in 1770 and was henceforth Cavaliere Cavaceppi. His sculptures were presented for sale in the Museo Cavaceppi between the Piazza di Spagna and the Piazza del Popolo, the part of Rome most frequented by foreigners.In the 1770s he carved a reduced version of Trajan's Column, which was purchased by the English virtuoso Henry Blundell to complement his antiqities at Ince Blundell; Blundell also acquired Cavaceppi's working model, a wooden column painted in grisaille.At the time of his death, the collection of fragments and casts in the Museo was vast. Prince Giovanni Torlonia purchased over a thousand items from Cavaceppi's legacy. In some senses, Vincenzo Pacetti, who had collaborated with Cavaceppi on restorations and who supervised restorations and display of the Borghese collection at Villa Borghese was Cavaceppi's successor.An exhibition "Bartolomeo Cavaceppi", curated by C.A. Picon in London, 1983, helped to bring him out of obscurity.
