Sperandio di Bartolommeo Savelli, Italian medallist, architect, sculptor, painter, bronzeGLOSSARYAn alloy of copper (usually about 90 per cent) and tin, often also containing small amounts of other metals such as lead or zinc. Since antiquity it has been the metal most commonly used in cast sculpture because of its strength, durability, and the fact that it is easily workable - both hot and cold - by a variety of processes. It is easier to cast than copper because it has a lower melting-point, and its great tensile strength makes possible the protrusion of unsupported parts - an advantage over marble sculpture. The colour of bronze is affected by the proportion of tin or other metals present, varying from silverish to a rich, coppery red, and its surface beauty can be enhanced when it acquires a patina. and cannon caster. He was the son of a Roman goldsmith, Bartolommeo di Sperandio Savelli. In c. 1437 the family left Mantua to settle in Ferrara, where Sperandio was probably trained in goldsmithing by his father. Sperandio is first mentioned as a goldsmith at Ferrara in 1445 and again in 1447. He appears to have returned to Mantua at some point and to have been employed by Borso d'Este, Marquess of Ferrara, by the early 1460s. His medalsGLOSSARYThe medal came to artistic maturity within a remarkably short time of its introduction in 15th century Italy. This was partly because ancient Roman coins, which were beginning to be reverently collected, suggested (on a smaller scale) its form: profile portrait bust on the obverse, a different design on the reverse, an inscription running round the rim. Like the finest Imperial coins, the medal's purpose was commemorative. Without monetary value, and of non-precious metal (bronze or lead), it was a way of circulating a likeness to a chosen few; it anticipated the use of miniatures and was indeed frequently worn round the neck. And while the reverse could record a historical event or make a propaganda point related to its subject's career, more commonly it bore a design that purported to convey the 'essence', as it were, of the person portrayed on the other side. Given the admiration for the men and artefacts of ancient Rome, the stress on individual character, the desire for fame and the penchant for summing up temperament in symbols and images, it is easy to understand how quickly the fashion for commissioning medals spread. Its pioneer executant was Pisanello. The precedents before he began to cast medals in 1438-39 had been few and excessively coin-like. Within 10 years he had established the form the medal was to retain until the influence was registered of the reverseless, hollow-cast and wafer-thin medals of the 1560s and 70s made by Bombarda (Andrea Cambi). Pisanello's approach was first echoed by the Veronese Matteo de' Pasti (d. 1467-688). It was, perhaps oddly, not until the works from 1485 of Niccolò Fiorentino (Niccolò di Forzore Spinelli, 1430-1514) that Florence produced a medallist of the highest calibre. Other specialists in the medium included Sperandio (Sperandio Savelli, c. 1425-1504), L'Antico (Pier Jacopo Alari Bonacolsi, c. 1460-1528), Caradosso (Cristoforo Caradosso Foppa, 1452-1526/27). The work of these men, and of the many, often anonymous, who reflected them, is still coveted because it avoided the two medallistic errors: making a medal look like either an enlarged piece of money or a small sculptured plaque. of Giovanni II Bentivoglio, Prince of Bologna, Bartolommeo Pendaglia, merchant at Ferrara, Giustiniano Cavitelli, jurisconsult at Cremona, and Antonio Sarzanella de' Manfredi of Faenza have been assigned to the early years of his first period in Ferrara (1462-77). The medal depicting Francesco Sforza, Duke of Milan (c. 1466), shows the sitter in three-quarter view (the only en faceGLOSSARYIn portraiture, a pose in which the sitter faces the viewer directly; full face. medallic work by Sperandio). It does not appear to have been executed from life, but from a painting or drawing.
After Borso d'Este's death and Ercole d'Este's accession to the duchy (1471), Sperandio appealed to him for assistance, and sent him, unsolicited, a medal with Ercole's portraitGLOSSARYThe Roman portrait bust survived in the form of life-sized reliquaries of saints, but it was in 15th century Florence that the individual features and character of a contemporary sitter were accurately recorded by sculptors such as Donatello, Desiderio da Settignano, Mino da Fiesole and the Rossellino. A similar degree of realism occurs in 15th century tomb sculpture. The equestrian portrait, based on antique statues such as the Marcus Aurelius monument (Rome, Campidoglio), was revived in the 14th century. Two examples in fresco are Simone Martini's Guidoriccio (c. 1328; Siena, Palazzo Pubblico) and the posthumous portrait of Sir John Hawkwood (1436; Florence, Cathedral) by Uccello, which gives the illusion of a 3-dimensional statue seen from below. The Venetian Republic ordered imposing monuments from Donatello (1447; Gattarnelata, Padua) and Verrocchio (14799; Colleoni, Venice), whilst other statesmen ordered their own images to be erected in public places, directly relating themselves to the military heroes of ancient Rome. Another form of political portraiture derived from antiquity was the commemorative portrait medal designed by artists such as Pisanello. The carved or painted profile portrait became popular in the 1450s. The realism of the clear, flattened image, painted under the influence of Flemish examples by the Pollaiuolo brothers, Piero della Francesca and Botticelli, was superseded by the three-quarter and frontal portrait, psychologically more complex, such as Leonardo's enigmatic Mona Lisa (Paris, Louvre) with her momentary smile or Andrea del Sarto's arresting Portrait of a Man (London, National Gallery). The 16th century portrait became generalized, Lotto's Andrea Odoni (1527; Royal Collection) being an idealized concept of a collector rather than an individual. Group portraits, decorating whole rooms, include the narrative scenes of the Gonzaga court painted by Mantegna (completed 1474; Mantua, Palazzo Ducale) and the elaborate schemes commissioned by the Farnese family in Rome from Vasari (1546; Palazzo della Cancelleria) and Salviati (after 1553; Palazzo Farnese). Portraits were also incorporated into religious narratives, as in Ghirlandaio's fresco cycle painted for Giovanni Tornabuoni in S. Maria Novella, Florence (1486-90).; the piece is probably the one mentioned in Ercole's inventory of 1471. Sperandio signs his letter 'Sperandio of Mantua, goldsmith living in Ferrara'. The appeal seems to have led to continuation of his employment, as records of 1475 show a payment to him for two marbleGLOSSARYloosely applied to any hard limestone that can be sawn into thin slabs and will take a good polish so that it is suitable for decorative work; more strictly, it refers to metamorphosed limestones whose structure has been recrystallized by heat or pressure. Marbles are widely disseminated and occur in a great variety of colours and patterns, but certain types have been particularly prized by sculptors. The most famous of Greek white marbles in the ancient world was the close-grained Pentelic, which was quarried at Mount Pentelicon in Attica. The Elgin Marbles are carved in Pentelic. Widely used also were the somewhat coarser-grained translucent white marbles from the Aegean islands of Paros and Naxos. Parian marble was used for the celebrated Mausoleum at Halicarnassus. The pure white Carrara marble, quarried at Massa, Carrara, and Pietra Santa in Tuscany from the 3rd century BC, is the most famous of all sculptors' stones. It was used for the Apollo Belvedere, and was much favoured in the Renaissance, particularly by Michelangelo, who often visited the quarries to select material for his work. Neoclassical sculptors also favoured Carrara marble because of its ability to take a smooth, sleek surface, but it can look rather 'dead' compared with some of the finest Greek marbles. busts executed for the duke (one in Paris, Louvre).
Sperandio was an artist of many talents - medalist, painter, goldsmith, architect, cannon founder, and sculptor - but he is known primarily for his medallic output. With forty-eight medals to his credit, he was among the most productive of fifteenth-century medalists, producing an impressive galleryGLOSSARYan upper story, similar to a tribune, running along the side of a building and open on one side to the interior; in a church (basilica) above the side aisles, over the ambulatory (central-plan building) and also over the west end. The gallery was used to keep certain groups of worshippers apart (women, noblemen). of representations and evocative portraits that seem to have captured vividly the character and personality of Renaissance man.
