Polychrome
Polychrome is the "practice of decorating architectural elements, sculpture, etc., in a variety of colors." The term is used to refer to certain styles of architecture, pottery, or sculpture in multiple colors.
When looking at artworks and architecture from antiquity and the European Middle Ages, people tend to believe that they were monochrome. In reality, the pre-Renaissance past was full of colour, and Greco-Roman sculptures and Gothic cathedrals, that are now white, beige, or grey, were initially painted in a variety of colours. As André Malraux stated: "Athens was never white but her statues, bereft of color, have conditioned the artistic sensibilities of Europe the whole past has reached us colorless." Polychrome was and is a practice not limited only to the Western world. Non-Western artworks, like Chinese temples, Oceanian Uli figures, or Maya ceramic vases, were also decorated with colours.
Ancient Near East
Similarly to the ancient art of other regions, Ancient Near Eastern art was polychrome, bright colours being often present. Many sculptures no longer have their original colouring today, but there are still examples that keep it. One of the best is the Ishtar Gate, the eighth gate to the inner city of Babylon. It was constructed in by the order of King Nebuchadnezzar II on the north side of the city. It was part of a grand walled processional way leading into the city. Its colours are as rich as they were back in the day because the walls were made of glazed brick.Many Ancient Near Eastern sculptures were painted too. Although they are grey today, all the Assyrian reliefs that decorated royal palaces were painted in highly saturated colours.
Ancient Egypt
Thanks to the dry climate of Egypt, the original colours of many ancient sculptures in round, reliefs, paintings, and various objects were well preserved. Some of the best preserved examples of ancient Egyptian architecture were the tombs, covered inside with sculpted reliefs painted in bright colours or just frescos. Egyptian artists primarily worked in black, red, yellow, brown, blue, and green pigments. These colours were derived from ground minerals, synthetic materials, and carbon-based blacks. Most of the minerals were available from local supplies, like iron-oxide pigments ; white derived from the calcium carbonate found in Egypt's extensive limestone hills; and blue and green from azurite and malachite.Besides their decorative effect, colours were also used for their symbolic associations. Colours on sculptures, coffins, and architecture had both aesthetic and symbolic qualities. Ancient Egyptians saw black as the colour of the fertile alluvial soil, and so associated it with fertility and regeneration. Black was also associated with the afterlife, and was the colour of funerary deities like Anubis. White was the colour of purity, while green and blue were associated with vegetation and rejuvenation. Because of this, Osiris was often shown with green skin, and the faces of coffins from the 26th Dynasty were often green. Red, orange, and yellow were associated with the sun. Red was also the colour of the deserts, and hence associated with Set and the forces of destruction.
Later, during the 19th century, expeditions took place that had the purpose of cataloging the art and culture of ancient Egypt. Description de l'Égypte is a series of early 19th century publications full of illustrations of monuments and artifacts of Ancient Egypt. Most are black-and-white, but some are colourful, so they can show the polychromy from the past. In some cases, only a few traces of paint remained on the walls, pillars and sculptures, but the illustrators attempted successfully at showing the buildings' original state in their pictures.
Classical world
Some very early polychrome pottery has been excavated on Minoan Crete such as at the Bronze Age site of Phaistos. In ancient Greece sculptures were painted in strong colors. The paint was frequently limited to parts depicting clothing, hair, and so on, with the skin left in the natural color of the stone. But it could cover sculptures in their totality. The painting of Greek sculpture should not merely be seen as an enhancement of their sculpted form but has the characteristics of a distinct style of art. For example, the pedimental sculptures from the Temple of Aphaia on Aegina have recently been demonstrated to have been painted with bold and elaborate patterns, depicting, amongst other details, patterned clothing. The polychrome of stone statues was paralleled by the use of materials to distinguish skin, clothing, and other details in chryselephantine sculptures, and by the use of metals to depict lips, nipples, etc., on high-quality bronzes like the Riace bronzes. The availability of modern digital methods and techniques have allowed the reconstruction and visualization of ancient 3D polychromy in a scientifically sound method and many projects have explored these possibilities in the last years.An early example of polychrome decoration was found in the Parthenon atop the Acropolis of Athens. By the time European antiquarianism took off in the 18th century, however, the paint that had been on classical buildings had completely weathered off. Thus, the antiquarians' and architects' first impressions of these ruins were that classical beauty was expressed only through shape and composition, lacking in robust colors, and it was that impression which informed neoclassical architecture. However, some classicists such as Jacques Ignace Hittorff noticed traces of paint on classical architecture and this slowly came to be accepted. Such acceptance was later accelerated by observation of minute color traces by microscopic and other means, enabling less tentative reconstructions than Hittorff and his contemporaries had been able to produce. An example of classical Greek architectural polychrome may be seen in the full size replica of the Parthenon exhibited in Nashville, Tennessee, US.
East Asia
Chinese art is known for the use of vibrant colours. Neolithic Chinese ceramic vessels, like those produced by the Yangshao culture, show the use of black and red pigments. Later, tomb and religious sculptures appear as a consequence of the spread of Buddhism. The deities most common in Chinese Buddhist sculpture are forms of the Buddha and the bodhisattva Guanyin. Traces of gold and bright colours in which sculptures were painted still give an idea of their effect. During the Han and Tang dynasties, polychrome ceramic figurines of servants, entertainers, tenants, and soldiers were placed in the tombs of people from upper-class. These figurines were mass-produced in moulds. Although Chinese porcelain is best known as being blue-and-white, many colorful ceramic vases and figures were produced during the Ming and Qing dynasties. During the same two dynasties, cloisonné vessels that use copper wires and bright enamel were also manufactured.Similarly to what was happening in China, the introduction of Buddhism in Japan in 538 lead to the production of polychrome Japanese Buddhist sculptures. Japanese religious imagery had until then consisted of disposable clay figures used to convey prayers to the spirit world.
Medieval
Throughout medieval Europe religious sculptures in wood and other media were often brightly painted or colored, as were the interiors of church buildings. These were often destroyed or whitewashed during iconoclast phases of the Protestant Reformation or in other unrest such as the French Revolution, though some have survived in museums such as the V&A, Musée de Cluny, and Louvre. The exteriors of churches were painted as well, but little has survived. Exposure to the elements and changing tastes and religious approval over time acted against their preservation. The "Majesty Portal" of the Collegiate church of Toro is the most extensive remaining example, due to the construction of a chapel which enclosed and protected it from the elements just a century after it was completed.17th and 18th centuries
While stone and metal sculpture normally remained uncolored, like the classical survivals, polychromed wood sculptures were produced by Spanish artists: Juan Martínez Montañés, Gregorio Fernández ; German: Ignaz Günther, Philipp Jakob Straub ; or Brazilian: Aleijadinho.Monochromatic color solutions of architectural orders were also designed in the late,
dynamic Baroque, drawing on the ideas of Borromini and Guarini. Single-colored stone
cladding was used: light sandstone, as in the case of the façade of the Bamberg Jesuit
church designed by Georg and Leonhard Dientzenhofer,
the façade of the monastery church in Michelsberg by Leonard Dientzenhofer, and
the abbey church in Neresheim by J.B. Neumann.
In the space of present-day Germany, during the 18th century, the Asam brothers designed churches with undulating walls, curved broken pediments and polychromy. In the German-speaking space, multiple Rococo churches and libraries with pastel polychrome stuccos and columns were built. There, faux marble columns are made from wood pillars that are covered in a layer of polychrome stucco, a mixture of plaster, lime, and pigment. When these ingredients are mixed, a homogenous-coloured paste is created. To achieve the marble look, thinner batches of darker and lighter paste are made, so that veins begin to appear. It is all roughly mixed by hand. When the material hardens it is polished by rubbing with fine sandpaper, and thus this layer of polychrome stucco becomes glossy and imitates really realistically marble. A good example of this is the Library of the Wiblingen Abbey in Ulm, Germany. Faux marble made of stucco will continue to be used during the 19th and early 20th centuries too. It is used only for interiors, because stucco dissolves outside through of contact with water.
In Wallachia, during the late 17th and early 18th centuries, the Brâncovenesc style was popular in architecture and decorative arts. It is named after Prince Constantin Brâncoveanu, during whose reign it was developed. Some of the churches in this style have polychrome facades, decorated with murals, like the church of the Stavropoleos Monastery in Bucharest, Romania.
The 2nd half of the 18th century was the rise of Neoclassicism, a movement which tries its best at reviving the styles of Ancient Greece, Rome, the Etruscan civilization, and sometimes even Egypt. During Louis XVI's reign, interiors in the Louis XVI style start to be decorated with arabesques, inspired by those discovered in ancient houses in Pompeii and Herculaneum. They are painted in pastel colours, painted white with the ornate parts gilt, or polychrome. The State Dining Room of the Inveraray Castle in Scotland, decorated by two French painters, is a good example of a polychrome Louis XVI style interior.
