Stosch, Ghezzi, and an Eighteenth-century Sculpture Restoration


Diogenes Relief. Villa Albani, inv. no. 161 On 8 May 1726, excavators discovered a marble bas relief in Monte Testaccio near Rome’s Porta di S. Paolo in Rome. Damaged and partial, it portrayed the philosopher Diogenes in a repaired pithos. In the background was a temple, and on top of the pithos was a dog—a symbolic allusion to the Cynic philosopher. The scene was a fragment of a larger image representing the fictional meeting of Diogenes and Alexander, so often discussed in classical literature and portrayed in early modern painting and sculpture.

The artist Pier Leone Ghezzi claimed that he purchased the relief while drinking in the Testaccio (famed for its wine cellars), paying one scudo for it.[i] Soon after its discovery, it entered the collection of the antiquarian-dealer Philipp von Stosch, who had it restored to the state in which it exists to the present day. In addition to some minor repairs, Stosch added the figure of Alexander as well as the head of Diogenes (derived from a statue in the Villa Albani).

The iconography of the bas relief recounts an anecdote told by authors such as Plutarch who claimed that when Alexander arrived in Corinth, every philosopher and statesman in the city went to greet him—everybody except Diogenes who stayed in the suburb of Craneion. This piqued Alexander’s curiosity, so he paid a visit the philosopher. He found Diogenes lying in the sun and asked him if he could give anything to him. The philosopher replied, “Yes, stand a little out of my sun.” Amused by Diogenes’ audacity, Alexander remarked, “If I were not Alexander, I would be Diogenes.”[ii]

The conditions of the discovery, restoration, and subsequent reproduction of the Diogenes relief provides insights into the nature of antiquarianism in the early eighteenth-century Italy. Since collections needed to serve as symbols of their owner’s wealth, power, knowledge, and/or taste, the material culture of the everyday—common tools and the detritus of daily life—were marginal. Throwaway items, such as undecorated pottery or the assemblages found in middens, were virtually ignored. This was a world that prioritized antique objects that could speak to aesthetic interests, mythological narratives, morality, the histories of great lives, and the administration of the state.

The types of ancient objects that most elites and scholars collected and reproduced in drawings and prints tended to be sculptures, gems, and intaglios—especially those that could illustrate accounts from ancient literary texts. Likewise, they might collect finely wrought decorative or religious object that could verify or supplement ancient descriptions of sacred and profane practices. The opus magnum of Bernard de Montfaucon—L'antiquité expliquée et représentée en figures (1719-24)is illustrative of these tendencies. Published in ten volumes with five supplements, it integrated objects from collections throughout Europe. It had four major sections. The first, concerned itself with the gods, temple architecture, and religious practices of the ancient Greeks and Romans as well as a number other related groups including the Egyptians, Persians, Scythians, Germans, Gauls, and Carthaginians. The second section focused on the practices of everyday life, including civic rituals. It examined clothing, furniture, marriages, games, festivals, and more. The third section discussed the practices of war, the nature of civic architecture (roads, bridges, aqueducts), as well as navigation and the construction ships. The final portion of the work emphasized the afterlife by describing ancient funerary practices as well as beliefs about the underworld. Nearly every object in Montfaucon’s volumes was of aesthetic, mythological, moral, or historical interest to contemporaries. Stosch’s bas relief would have fit in perfectly in that it spoke to both a moral and historical narrative.

For every excavated object perceived to be of aesthetic or intellectual value, settecento diggers and dealers discarded many others. Stosch’s Diogenes bas relief was found among thousands of objects at Monte Testaccio (sometimes known as Doliolum)—mostly olive oil amphorae disposed there during the second and third century. They generally ignored these objects even though many of the jars included tituli picti, inscriptions that contained data essential to tracing the economies of the ancient olive oil trade, central to Rome’s power.[iii] To eighteenth-century excavators these were utilitarian vessels and held minimal interest. Montfaucon for example had little to say about the area: “The Hill call’d Doliolum, and Mons Testaceus, had both those Names given it from many Pieces of Casks found in it.” He directed his readers to consult the work of Flaminio Vacca who, in passing, “mentions some things dug up there.”[iv]

While limiting their interests to a narrow range of ancient material culture, early eighteenth-century collectors and scholars were keen to restore their damaged antiquities to a pristine state. Stosch’s bas relief had survived since antiquity, but it was incomplete and had sustained significant damage. Thus, he sought out a conservator, perhaps from the workshop of Carlo Antonio Napolioni who was the preferred restorer of Cardinal Alessandro Albani, Stosch’s patron and fellow scholar. Napolioni was the first among many Roman experts who could salvage fragments and combine them into meaningful wholes—whether or not they reflected the original subject of the work.[v] Other restorers included the French artist Pierre Étienne Monnot, infamous in the late eighteenth century for transforming a Discobolus into a Wounded Gladiator.

The practice of reconstruction reflected shifting attitudes towards antiquity and scholarship during the eighteenth century. In the early decades, a radical intervention, à la Monnot, was not uncommon. By the end of the century artists and scholars alike emphasized the beauties of the unreconstructed object.

Stosch and his circle, which was active between the 1710s and 1750s, saw no problem in significantly restoring works, even if the retrofitted objects were quite imaginative by modern standards. The key was to attempt accurate reconstructions of the past. This did not mean a meticulous reproduction of the original object. Rather, “accuracy,” as it was understood in the practice of restoration during the early eighteenth century, meant veracity to the spirit of the object and its creators.[vi] In this sense, antiquity was something with which the moderns could creatively engage and reshape. Even as they looked to the past, they saw the object evolving with needs of modern society.

Driving this creative appropriation of the past during the early eighteenth century was the profoundly influential aesthetic and intellectual trail of the Renaissance, partly sustained by institutional systems, theories, and modes of practice created between the fifteenth and eighteenth centuries but also shaped by the quickly expanding commercial art trade, which, especially in Britain, placed a premium on Old Masters.[vii] Consequently, Renaissance models often provided the templates for reconstructions and restorations in the early eighteenth century. Thus, the settecento approach to the ancient world was one filtered through the classicizing lens of artists and architects such as Alberti, Palladio, Raphael, Michelangelo, and Poussin. Given this context, it is not surprising that Stosch’s imaginative restoration of the right half of his new bas relief followed that of the early modern masters, echoing Salvator Rosa’s version of the meeting of Diogenes and Alexander

Given that any item in a collection existed within a larger cultural field in which connoisseurs and collectors vied for influence and prestige, it is necessary to see objects in dialogue with contemporary interests. Likewise, it is important to understand that objects participated in a network of objects, cultural dispositions, and social practices. They were part of larger assemblages—of paintings, books, prints, drawings, coins, medals and more, which included both ancient and contemporary creations. Eighteenth-century collectors had an interest in circulating images of objects in their collections. This was how they developed a reputation for knowledge and taste. Thus, they wanted artists and connoisseurs to visit their cabinets. They encouraged the reproduction of their collections through prints and drawings. They might even commission works of art which highlighted their erudition and taste.

As a dealer whose finances depended on his ability to convince others of his intellectual and aesthetic superiority, Stosch used the Diogenes relief to bolster his reputation. In quick succession, he commissioned two works which celebrated the new addition to his collection. The first was a medal, designed by François Marteau. On the obverse was a classicized head of Stosch, and on the reverse was a representation of Stosch’s bas relief. The figure of Alexander and a few other additions and alterations suggest that the image stamping of the medal was completed before the reconstruction of the bas relief. Nevertheless, they still follow the general layout of Salvator Rosa.

Stosch’s second commission was a historical painting of the meeting of Diogenes and Alexander by Pier Leone Ghezzi. He followed the iconographic program of Salvator Rosa, making it a point to make Stosch and himself central figures in the image—confronting the viewer eye-to-eye and standing just behind the vessel in which Diogenes sits. These creations were part of a larger group of works that Stosch commissioned between the 1710s and 1740s, including medals by François Marteau and Giovanni Pozzo; intaglios by Francesco Ghinghi and Lorenz Natter; a bust by Edmé Bouchardon; as well as a series of prints and books that reproduced his portrait and objects from his collections.[viii]

As a spy, a sometimes dubious dealer, and even a thief at times, Stosch relied on the support of Cardinal Albani to elevate his reputation. Albani’s purchase of Stosch’s collection as well as his commission of Johann Joachim Winckelmann’s to catalog it was central to preserving his intellectual legacy. Eventually, Winckelmann even reproduced the Diogenes and Alexander bas relief in his Monumenti Antichiti.
