Bacchus

In Greek and Roman mythology, the god of wine and fertility. Bacchic rites were often orgiastic.

baldachin, or baldacchino (It. "brocade")

Originally a textile canopy supported on poles and carried dignitaries and relics. Later, an architectural canopy of stone or wood set over a high altar or bishop's throne.

balustrade

A rail supported by a row of small posts or open-work panels.

Bambocciati

Group of relatively small, often anecdotal, paintings of everyday life, made in Rome in the mid-17th century. The word derives from the nickname "Il Bamboccio" ("Large Baby"), applied to the physically malformed Dutch painter Pieter van Laer (1592/95-1642). Generally regarded as the originator of the style and its most important exponent, van Laer arrived in Rome from Haarlem about 1625 and was soon well known for paintings in which his Netherlandish interest in the picturesque was combined with the pictorial cohesiveness of Caravaggio's dramatic tenebrist lighting. Because van Laer and his followers depicted scenes of the Roman lower classes in a humorous or even grotesque fashion, their works were condemned by both court critics and the leading painters of the classicist-idealist school as indecorous and ridiculous. The painter Salvator Rosa was particularly savage in his comments about the later followers of the style, whom he criticized for painting "baggy pants, beggars in rags, and abject filthy things." The Bamboccianti (painters of Bambocciati) influenced such Dutch genre painters as Adriaen Brouwer and Adriaen van Ostade.

banderole (It. banderuola, "small flag")

A long flag or scroll (usually forked at the end) bearing an inscription. In Renaissance art they are often held by angels.

baptistery

Hall or chapel situated close to, or connected with, a church, in which the sacrament of baptism is administered. The form of the baptistery originally evolved from small, circular Roman buildings that were designated for religious purposes (e.g., the Temple of Venus, Baalbek, Lebanon, AD 273, and the Mausoleum of Diocletian, Spalato [Split, Croatia], AD 300); but because baptism originally was performed on only three holidays, Easter, Pentecost, and Epiphany, enlargement of the older Roman buildings became necessary to accommodate the growing numbers of converts.

Baptisteries were among the most symbolic of all Christian architectural forms; and the characteristic design that was developed by the 4th century AD can be seen today in what is probably the earliest extant example, the baptistery of the Lateran palace in Rome, built by Sixtus III, pope between 432 and 440.

The baptistery was commonly octagonal in plan, a visual metaphor for the number eight, which symbolized in Christian numerology a new beginning. As eight follows the "complete" number, seven, so the beginning of the Christian life follows baptism. Customarily, a baptistery was roofed with a dome, the symbol of the heavenly realm toward which the Christian progresses after the first step of baptism. The baptismal font was usually octagonal, set beneath a domical ciborium, or canopy, and encircled by columns and an ambulatory--features that were first used in the baptistery by the Byzantines when they altered Roman structures.

Baptisteries commonly adjoined the atrium, or forecourt, of the church and were often large and richly decorated, such as those at Pisa, Florence, Parma, and Nocera in Italy; el Kantara, Alg.; and Poitiers, France. After the 6th century they were gradually reduced to the status of small chapels inside churches. In the 10th century, when baptism by affusion (pouring liquid over the head) became standard practice in the church, baptisteries, or baptismal chapels, were often omitted entirely.

In most modern churches the font alone serves for baptism; something of earlier symbolism survives, however, in its usual location near the church door - an allusion to entering the Christian life.

Barbizon School

A group of naturalist landscape painters who worked in the vicinity of Barbizon, a village on the outskirts of the Forest of Fontainebleu, southeast of Paris, in the 1840s and 1850s. Théodore Rousseau (French, 1812-1867) was the founder of the group. Other members of the group were Jean-Baptist Corot (French, 1796-1875), Narcisse Diaz de la Pena (French, 1807-1876), Constant Troyon (French, 1810-1865), Jules Dupré (French, 1811-1889), Jean-François Millet (French, 1814-1875), and Charles-François Daubigny (French, 1817-1878). Their approach constituted an art movement which eventually led to both Realism and Impressionism. Daubigny was the first of the plein air painters.

Baroque (Port. barocco, "an irregular pearl or stone")

The period in art history from about 1600 to about 1750. In this sense the term covers a wide range of styles and artists. In painting and sculpture there were three main forms of Baroque: (1) sumptuous display, a style associated with the Catholic Counter Reformation and the absolutist courts of Europe (Bernini, Rubens); (2) dramatic realism (Caravaggio); and (3) everyday realism, a development seen in particular in Holland (Rembrandt, Vermeer). In architecture, there was an emphasis on expressiveness and grandeur, achieved through scale, the dramatic use of light and shadow, and increasingly elaborate decoration. In a more limited sense the term Baroque often refers to the first of these categories.

The development of the Baroque reflects the period's religious tensions (Catholic versus Protestant); a new and more expansive world view based on science and exploration; and the growth of absolutist monarchies.

barrel vault

A ceiling that is like a continuous circular arch or tunnel, contrasted with vaults that are supported on ribs or a series of arches. Also tunnel vault.

basilica (Gk. stoa basilike, "king's hall")

a church building, usually facing east, with a tall main nave and two or four side aisles of lesser height. There may also be a transept between the nave and the choir, which is reserved for the clergy. Originally, the basilica was an ancient Greek administrative building, and the Romans used this form for markets and law courts; it then became a place of assembly for the early Christians, and thus a church.

Battle of Lepanto

Naval battle during the course of which the 208 ships belonging to the Holy League gained a decisive victory on 7 October 1571 over the 210 ships of the Ottoman Turkish fleet on the edge of the Gulf of Corinth.

Biedermeier

Term applied to a style characteristic of much German and Austrian art and interior decoration in the period roughly between the end of the Napoleonic Wars (1815) and the Year of Revolutions (1848). The name derives from a fictional character called Gottlieb Biedermaier (sic) from the journal Fliegende Elssner (Flying Leaves), who personified the solid yet philistine qualities of the bourgeois middle classes, and the art to which he lent his name eschewed flights of the imagination in favour of sobriety, domesticity, and often sentimentality. There were, as is to be expected, no major painters associated with Biedermeier but many excellent practitioners, such as Waldmüller. The term is sometimes extended to cover the work of artists in other countries.

biscuit

Unglazed ceramic, particularly porcelain, which is either not yet glazed, or which is to be left as it is. Biscuit porcelain, also incorrectly called bisque, is often employed to make miniature versions of marble statuary. It takes its name from its grainy texture.

Bolognese school

In the most restricted sense, the works produced and the theories expounded by the late 16th- and early 17th-century Italian painters Lodovico Carracci and his cousins, the brothers Agostino and Annibale Carracci.

Book of Hours

A prayer book used by laymen for private devotion, containing prayers or meditations appropriate to certain hours of the day, days of the week, months, or seasons. They became so popular in the 15th century that the Book of Hours outnumbers all other categories of illuminated manuscripts; from the late 15th century there were also printed versions illustrated by woodcuts. The most famous Book of Hours and one of the most beautiful of all illuminated manuscripts is the Très Riches Heures du duc de Berry (Musée Condé, Chantilly), illuminated by the Limburg Brothers for Jean de Berry.

bottom view

A form of perspective in painting that takes account of the viewer's position well below the level of the picture.

bozzetto(Italian, sketch)

Usually applied to models for sculpture, but can also be used for painted sketches, though these are more often called 'modelli'.

bozzetto

Strictly speaking, a small three-dimensional sketch in wax or clay made by a sculptor in preparation for a larger and more finished work. By extension, a rapid sketch in oil, made as a study for a larger picture.

breviary

A book of daily prayers and readings used by priest and monks.

bronze

An 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.

buttress

A mass of stone built up to support a wall, usually necessary to strengthen those of great height. See flying buttress.

Byzantine art

The art ofthe Byzantine Empire, which had its capital in Constantinople (Byzantium), from the 5th century to the fall of Constantinople to the Turks in 1453. Based largely on Roman and Greek art, Byzantine art also absorbed a wide of influences, notable from Syria and Egypt. Byzantine art was essentially a spiritual and religious art, its forms highly stylized, hieratic and unchanging (central images were thought to derive from original portraits). It also served to glorify the emperor. Among its most distinctive products were icons, mosaics, manuscript illuminations, and work in precious metals. The strong influence of the Byzantine style on medieval Italian painting can be seen in the works of Cimabue, Duccio, and Giotto.
