Plaquettes are small metal reliefs, typically cast in bronze, which belong to the category of Renaissance sculpture. The academic study of plaquettes did not develop until the 1860s during which time the term “plaquette” was invented by the French scholar Eugene Piot. Most early scholars of plaquettes resided in France, Germany and Britain although knowledgeable Italian dealers like Stefano Bardini were at the forefront of encouraging Europe’s supply and interest in them through their sale to museums and collectors.
Before their categorization, plaquettes were referred to as piastre, medaglietti and rilievi. Their function as small reliefs was varied during the Renaissance. Plaquettes permeated fashion, were incorporated with utilitarian desktop objects, used as objects of devotion, as decorations for the arms trade, employed in book-binding and were also revered simply as objects-of-virtue. Their reproductive nature also allowed them to serve as models of reference for various artistic tradecrafts like architecture, sculpture, painting and manuscript illumination. As will be discussed, the eight plaquettes featured in the present exhibition touch upon these varied applications and uses.
The Italian appreciation of plaquettes by Renaissance high-society is evinced by the sculptor Moderno (Galeazzo Mondella) whose prolific activity of specializing in small reliefs indicates their appeal during the last part of the Quattrocento and beginning of the Cinquecento. The earlier origin of the plaquette, with its genesis in the 1430s, is due to the influence of Donatello and his circle of collaborators who experimented with the serial facture of devotional reliefs in bronze. In Rome, Filarete likewise experimented with small devotional and secular reliefs in bronze, contributing also to their early development. 
It is the assembly of these small disparate reliefs into collected groups that eventually became the impetus for plaquettes as an art historical category. One of the earliest known collected group of plaquettes was formed in the first decades of the 16th century near Padua at the Castello di Cataio, which by descent, now forms part of the modern day Kunsthistorisches collection in Vienna, Austria. Similarly, the Munich Kunstkammer, completed in 1578, also included a small group of plaquettes. An early collector of plaquettes was Erasmus of Rotterdam who acquired several in Italy during his travels there in 1506-09 which now form part of the Amerbach Kabinett at the Historisches Museum in Basel. The earliest significant group of collected plaquettes in which specific examples are identifiable through descriptive entries are those assembled by John Tradescant the Elder during the late 16th and early 17th century, now forming part of the Ashmolean Museum collections.
As humanism spread across Europe so too did an interest in the plaquette. Over the centuries other royals, nobles and men of erudition and curiosity assembled groups of plaquettes which would later comprise the bulk of various collections found today in museums. In the taste of other enterprising nobles of the late 19th century, the Cagnola family also formed a pleasing group of plaquettes which today reside at the Villa Cagnola (Fig. 01).
THE KINSHIP BETWEEN PLAQUETTES, BOOKS AND THE INDUSTRY OF PRINTING
Of interest to the present exhibit are the selection of Renaissance books in the Cagnola library which offer a window into Italy’s cultural milieu of the period and its classical revival of the antique past. These books elaborate the wisdom of the ancients, cloaked in moral allegories and mythological accounts. It is from these themes, so often revitalized in other media like painting, poetry and free-standing sculpture, that the low-relief, miniature yet tactile beauty of plaquettes are equally expressed.
Books and plaquettes share an infrequent but fascinating connection with the incorporation of their designs on late 15th century and early-to-mid 16th century Italian bindings. For example, a cast of the Apotheosis of Scipio by Valerio Belli, represented by one example in the Cagnola collection, is also known by a singular example at the Civic Museum of Vicenza which has been cast in reverse, used as a matrix for blind-stamping the plaquette’s design on the leather binding of books. Several of Belli’s plaquettes were used for book bindings, such as those in the library of the Escorial, on books belonging to the Spanish Ambassador Diego Hurtado de Mendoza, published in Venice during the early 1540s.
Two other plaquettes represented by examples in this exhibit have also been reproduced on Milanese bindings commissioned by Jean Grolier between 1510-16. The Sacrifice of Marcus Curtius by the Master IO.F.F., for example, appears along with his Horatius Cocles Defending the Bridge, blind-stamped onto a leather binding of Aristotle’s Opera Gracce published in Venice in 1498 (British Library). Another book from Grolier’s library, a 1504 Venetian edition of John Philoponus’ 6th century Commentary on Aristotle’s Posterior Analytics features Moderno’s Battle Scene (Fig. 02). Plaquettes in applique-form, sometimes cast in finer metals like gold and silver, were also occasionally used for the ornamentation of bindings.
Prior to their feature on bindings, plaquettes cast from antique or contemporary hardstones (or derivative plaster impressions thereof) earlier served as models for the illumination of manuscript borders celebrating the classical past. However, later well circulated plaquettes also inspired illuminators such as Narziss Renner in Augsburg, responsible for the 1521 prayer book of Matthaus Schwarz who reproduced two plaquettes also represented by examples in the present exhibit: Moderno’s Cacus Stealing the Oxen of Hercules and IO.F.F.’s Triumph of Prudence (Fig. 03).
Though infrequent, plaquettes have also served as models for images intended for books, for example Doug Lewis notes a full-page woodcut featured in Francesco Colonnna’s Hynperotomachi Poliphili (Venice, 1499) (Fig. 04) was probably based upon the Sacrifice of Marcus Curtius by the Master IO.F.F.
Individual prints have certainly been based upon plaquette designs, as the same aforementioned plaquette inspired a slightly later woodcut by Lucas Cranach the Elder, ca. 1506 (Fig. 05). In contrast, woodcuts and engravings have also occasionally served as models for some plaquette makers, especially North of the Alps.
Also of note is the influence of humanistic literature on the clever and occasionally genius designs of plaquette artists. Their compositions indicate these artists were as cultured as the educated patrons they served. For example, Francesco Rossi comments on the assured familiarity of the Master of the Orpheus Legend with the humanist literature of the period, pointing to a possible familiarity with the work of Angelo Poliziano at the Medici court. John Spencer interestingly proposed Moderno’s series of reliefs involving the struggles of Hercules and Cacus were not a simple reproduction of antique myth but were rather an interpretive allegory of fortitude inspired by antique and early Christian commentaries on Virgil’s Aenid. Lewis notes that Moderno may have had access to humanists from the Ferrarese court like Antonio Tebaldeo and Laura Brenzoni Schioppo by way of his brother Girolamo. The avant-garde designs of IO.F.F. indicate a rich and complex knowledge of the literature from the period. Most recently, Lewis has pointed out that IO.F.F.’s Sacrifice of Marcus Curtius is a Christianized depiction of the myth possibly inspired by an episode from the Gesta Romanorum.
THE PLAQUETTE IN OTHER MEDIA
Plaquettes also served as models for other forms of two-dimensional art, especially those tied to the minor arts. Two examples concerning plaquettes in the present exhibit are a niello reproducing Moderno’s Cacus Stealing the Oxen of Hercules (Fig. 06) and another which adapts IO.F.F.’s Triumph of Prudence.
With their origin in sculpture, plaquettes also came to influence other works of the genre, especially in relief. For example, Moderno’s Cacus Stealing the Oxen of Hercules found a certain favor in the region of Blois, France where it is reproduced in stone on the city’s main Chateau, ca. 1515-24 and also nearby in Olréans on an oak door, ca. 1520-30, where it is intricately carved on the left-register of its tympanum (Fig. 07).  
Of noteworthy import is the scarce plaquette of Mars, Venus and Cupid at the Forge of Vulcan by the Master of the Orpheus Legend, an example of which is presented in the current exhibition. The plaquette was likely executed in the same period as a large and masterful silver and gold gilt bronze roundel of the same subject, attributed to Gian Marco Cavalli in Mantua and one of the most significant sculptural works of Mantua discovered in recent years (Fig. 08). The presence of an unusually winged Venus in the scene may suggest a common source, possibly literary, for both reliefs or perhaps the influence of one artist’s work upon the other which remains possibile considering Cavalli was himself involved in the execution of small reliefs as a goldsmith and medal-maker.
Another example for the translation of plaquettes into sculpture is Cristoforo di Geremia’s Sacrifice to Cupid, represented by a rare example in this exhibit, which served as the model for a motif depicted on a marble relief by Giovanni Antonio Amadeo executed between 1478-80 for the tabernacle of the Virgin at the Milan Cathedral (Fig. 09).
The Sacrifice to Cupid represents one of the earliest uses of small relief on utilitarian objects of the Renaissance, serving as the lid to a classicized oil lamp, one of which survives intact at the Victoria & Albert Museum (Fig. 10). These lamps were so convincing in their design and decorative program that the early 17th century antiquarians Paul Petau and Fortunatus Scacchus believed them to be authentic ancient Roman lamps.
In the round, a sculpted Chimera in the form of an inkwell and candlestick by Severo da Ravenna (Fig. 11), incorporates a sword pommel depicting Moderno’s Battle Scene plaquette while a satyr-adorned perfume burner attributed to Desiderio da Firenze features Moderno’s Cacus Stealing the Oxen of Hercules on its base (Fig. 12). While not the exclusive work of Moderno himself, these functional sculptures exemplify the way in which small reliefs could posthumously be appropriated with other dynamic works-of-art.
It was also common for later workshops, perhaps often provincial ones, to appropriate or plagiarize circulating plaquette reliefs for use on other objects. One example is an independent side-panel for a desk casket at the Palazzo Madama, crudely reproducing Belli’s Apotheosis of Scipio or another reproducing the Orpheus Master’s Mars, Venus and Cupid at the Forge of Vulcan, redacted from its circular format for use on a casket panel probably forming one side of a sand-box (Fig. 13).
Of final note is the incorporation of plaquettes on sword hilts. All of the major plaquette artists: Moderno, IO.F.F. and Riccio, were involved in producing plaquettes for the arms industry. Chief among them was IO.F.F. whose output probably also included the creation of the pommels as well. The influence of his work carried over into other facets of the trade where one can observe Bolognese sword sheaths and damascened or engraved blades reproducing scenes characteristic of IO.F.F.’s style or in some cases reproducing his designs. For example, an Emilian short-sword, ca. 1480-1500 at the Museo Bardini (Florence) features IO.F.F.’s Triumph of Prudence engraved on its blade.
Although it is a later aftercast, the rare example of IO.F.F.’s Sacrifice of Marcus Curtius featured in this exhibit is the only known surviving example of the relief displayed in its original context as a sword pommel. The pommel reproduces a type intended for IO.F.F.’s “shield shaped” plaquettes which Mario Scalini has noted was probably a pommel more practical in its functionality for battle than IO.F.F.’s other pommels intended for dress swords. A pommel-type like the one featured here on the Cagnola example is eloquently reproduced in Amico Friulano del Dosso’s Portrait of a Man, ca.1515-20 (cover image / Fig.14).
