Italian painter and copyist. He was a pupil of Francesco Albani, whose influence is apparent in his early altarpieceGLOSSARYA picture or sculpture that stands on or is set up behind an altar. The term reredos is used for an ornamental screen or partition, not directly attached to the altar table but affixed to the wall behind it. A diptych is an altarpiece consisting of two panels, a triptych one of three panels, and a polyptych one of four or more panels. From the 14th to 16th century, the altarpiece was one of the most important commissions in European art; it was through the altarpiece that some of the most decisive developments in painting and sculpture came about. of St Lawrence (c. 1654; Ravenna, Santa Maria in Porto). He may subsequently have studied with Carlo Cignani, with whom he collaborated on frescoes (e.g. Francis I ) in the SalaGLOSSARYHall, large room. Farnese, PalazzoGLOSSARYPalaces: large urban dwellings, 'palazzo' in Italian carries no regal connotations. Alberti described the palace as a city in little, and, like cities, Italian Renaissance palaces vary in type according to differences of climate, tradition and social structure. On to these regional stocks were grafted new architectural strains, reflecting theoretical reinterpretations of antiquity and individually influential examples. The atrium and peristyle house described by Vitruvius and now known from Pompeii did not survive antiquity, and much of the interest of Renaissance designs lies in creative misunderstandings of Vitruvius's text. Medieval palace architecture probably inherited the insula type of ancient apartment house, related to the modest strip dwellings which never disappeared from Italian cities. In Florence a merchant palace developed from fortified beginnings, with vaulted shop openings on the ground floor, and the main apartments above, reached by internal stone staircases opening from an inner court. Renaissance developments regularized without changing the essential type, although large cloister-like courtyards were introduced, while shops came to be thought undignified. At Michelozzo's Medici Palace (1444) a square arcaded courtyard with axial entrance lies behind a façade of graduated rustication, with biforate windows, a classical cornice replacing the traditional wooden overhang. The apartments on the 'piano nobile' formed interconnecting suites of rooms of diminishing size and increasing privacy. The classical orders which Alberti introduced to the façade of the Palazzo Rucellai (c.1453) were not taken up by the conservative Florentines, who continued to build variations on the Medici Palace (Palazzo Pitti; Palazzo Strozzi). In the 16th century rustication was reduced to quoins and voussoirs, and large windows appeared on the ground floor, 'kneeling' on elongated volutes. At Urbino the Ducal Palace (1465) reflected Alberti's recommendations for the princely palace, and was in turn influential on late 15th century palaces in Rome (e.g. the Cancelleria). A harmonious Florentine courtyard and ample staircase replace the embattled spaces of medieval seigneurial castles, of which vestiges remain only in the towers flanking the balconies of the duke's private apartments, designed as a scholarly retreat. In the absence of a merchant class or a cultured nobility in 15th century Rome, the architectural pace was set by the papal court. Papal incentives to build, and large households, meant less compact plans for cardinals' palaces, often built next to their titular churches. Renaissance forms appear in the unfinished courtyard of the Palazzo Venezia (1460s), with its arcade system derived from the nearby Theatre of Marcellus, and in the delicately ordered stonework of the Cancelleria (1485). In the 16th century vestigial corner towers and shops disappear from cardinals' palaces, and Antonio da Sangallo's Palazzo Farnese (1516) introduces symmetrical planning and Vitrivuan elements, like the colonnaded vestibule, behind a sober Florentine façade, enlivened by Michelangelo's cornice. A smaller palace type supplied the needs of an enlarged papal bureaucracy, more ambitious for display than for domestic accommodation. Bramante's 'House of Raphael' sets the façade style not only for this new type, but also for Renaissance houses all over Europe. Raphael and Peruzzi made ingenious use of difficult sites (Palazzo da Brescia; Palazzo Massimi), and their sophisticated façades flattered the architectural pretensions of patron and pope (e.g. Palazzo Branconio dell'Aquila). Movement of patrons and architects, especially after the Sack of Rome, meant a diffusion of Roman forms to central and northern Italy, where Sanmicheli's palaces in Verona, and Palladio's in Vicenza, adapted Roman types to suit local conditions. Palladio's 4-columned atrium is a Vitruvian solution to the traditionally wide Veneto entrance hall, and his plan for the Palazzo da Porto-Festa contains explicit references to Vitruvius's House of the Greeks. In Venice, defended by its lagoon and a stable political system, the hereditary aristocracy built palaces open to trade and festivity on the Grand Canal. The traditional Venetian palace has a tripartite structure: long central halls above entrance vestibules used for unloading merchandise are lit on the canal façade by clusters of glazed windows (rare elsewhere), and at the back from small courts with external staircases (as in the Ca' d'Oro). Codussi's palaces introduced biforate windows and a grid of classical orders into the system, while Sansovino's Palazzo Cornaro retains vestiges of the Venetian type (small courtyard; tripartite façade) despite its Bramantesque coupled orders and licentious window surrounds. Other cities, like Genoa, evolved influential types. Through engravings and the illustrated treatises, Italian Renaissance ideas of palace planning, originally evolved in response to specific conditions, came to be applied all over Europe. Pubblico, Bologna (1658-60; in situ), and, later, on frescoes representing scenes from the Life of St Andrew in Sant'Andrea della Valle, Rome (1662-65; in situ). His few surviving works also include two undated altarpieces: SS John Abbot and Maurice (Parma, San Giovanni Evangelista) and the Virgin with SS Martin, Agnes and Christina (Casalvecchio di Reno, nr Bologna, parish church). The Virgin Appearing to St Peter Celestine (1682; San Giovanni Battista dei Celestini, Bologna) is his best-known painting. It exhibits his familiarity with the works of Annibale Carracci and Guercino, and is notable for its stylish incorporation of the classicalGLOSSARYRelating to the culture of ancient Greece and Rome (classical Antiquity). The classical world played a profoundly important role in the Renaissance, with Italian scholars, writers, and artists seeing their own period as the rebirth (the "renaissance") of classical values after the Middle Ages. The classical world was considered the golden age for the arts, literature, philosophy, and politics. Concepts of the classical, however, changed greatly from one period to the next. Roman literature provided the starting point in the 14th century, scholars patiently finding, editing and translating a wide range of texts. In the 15th century Greek literature, philosophy and art - together with the close study of the remains of Roman buildings and sculptures-expanded the concept of the classical and ensured it remained a vital source of ideas and inspiration. conventions of Bolognese painting.
