Relief is a sculpture method in which the sculpted pieces remain attached to a solid background of the same material. The term is from the Latin verb relevare, to raise (). To create a sculpture in relief is to give the impression that the sculpted material has been raised above the background plane. When a relief is carved into a flat surface of stone (relief sculpture) or wood (relief carving), the field is actually lowered, leaving the unsculpted areas seeming higher. The approach requires chiselling away of the background, which can be time-intensive. On the other hand, a relief saves forming the rear of a subject, and is less fragile and more securely fixed than a sculpture in the round, especially one of a standing figure where the ankles are a potential weak point, particularly in stone. In other materials such as metal, clay, plaster stucco, ceramics or papier-mâché the form can be simply added to or raised up from the background. Monumental bronze reliefs are made by casting.
There are different degrees of relief depending on the degree of projection of the sculpted form from the field, for which the Italian and French terms are still sometimes used in English. The full range includes high relief (Italian alto-rilievo, French haut-relief),In modern English, just "high relief"; alto-rilievo was used in the 18th century and a little beyond, while haut-relief surprisingly found a niche, restricted to archaeological writing, in recent decades after it was used in under-translated French texts about prehistoric cave art, and copied even by English writers. Its use is to be deprecated. where more than 50% of the depth is shown and there may be undercut areas, mid-relief (Italian mezzo-rilievo), low relief (Italian basso-rilievo, French: bas-relief), and shallow-relief (Italian rilievo schiacciato),Murray, Peter & Linda, Penguin Dictionary of Art & Artists, London, 1989. p. 348, Relief; bas-relief remained common in English until the mid 20th century. where the plane is only very slightly lower than the sculpted elements. There is also sunk relief, which was mainly restricted to Ancient Egypt ( see below). However, the distinction between high relief and low relief is the clearest and most important, and these two are generally the only terms used to discuss most work.
The definition of these terms is somewhat variable, and many works combine areas in more than one of them, rarely sliding between them in a single figure; accordingly some writers prefer to avoid all distinctions.For example Avery in Grove Art Online, whose long article on "Relief sculpture" barely mentions or defines them, except for sunk relief. The opposite of relief sculpture is counter-relief, intaglio, or cavo-rilievo,Murray, 1989, op.cit. where the form is cut into the field or background rather than rising from it; this is very rare in monumental sculpture. Hyphens may or may not be used in all these terms, though they are rarely seen in "sunk relief" and are usual in "bas-relief" and "counter-relief". Works in the technique are described as "in relief", and, especially in monumental sculpture, the work itself is "a relief".
Reliefs are common throughout the world on the walls of buildings and a variety of smaller settings, and a sequence of several panels or sections of relief may represent an extended narrative. Relief is more suitable for depicting complicated subjects with many figures and very active poses, such as battles, than free-standing "sculpture in the round". Most ancient architectural reliefs were originally painted, which helped to define forms in low relief. The subject of reliefs is for convenient reference assumed in this article to be usually figures, but sculpture in relief often depicts decorative geometrical or foliage patterns, as in the arabesques of Islamic art, and may be of any subject.
are those carved into solid rock in the open air (if inside caves, whether natural or human-made, they are more likely to be called "rock-cut"). This type is found in many cultures, in particular those of the Ancient Near East and Buddhist countries. A stele is a single standing stone; many of these carry reliefs.
Low relief is a technique which requires less work than high relief, and is therefore cheaper to produce, as less of the background needs to be removed in a carving, or less modelling is required. In the art of Ancient Egypt, Assyrian palace reliefs, and other ancient Near Eastern and Asian cultures, a consistent very low relief was commonly used for the whole composition. These images would usually be painted after carving, which helped define the forms; today the paint has worn off in the great majority of surviving examples, but minute, invisible remains of paint can usually be discovered through chemical means.
The Ishtar Gate of Babylon, now in Berlin, has low reliefs of large animals formed from moulded bricks, glazed in colour. Plaster, which made the technique far easier, was widely used in Egypt and the Near East from antiquity into Islamic times (latterly for architectural decoration, as at the Alhambra), Rome, and Europe from at least the Renaissance, as well as probably elsewhere. However, it needs very good conditions to survive long in unmaintained buildings – Roman decorative plasterwork is mainly known from Pompeii and other sites buried by ash from Mount Vesuvius. Low relief was relatively rare in Western medieval art, but may be found, for example in wooden figures or scenes on the insides of the folding wings of multi-panel .
The revival of low relief, which was seen as a classical style, begins early in the Renaissance; the Tempio Malatestiano in Rimini, a pioneering classicist building, designed by Leon Battista Alberti around 1450, uses low reliefs by Agostino di Duccio inside and on the external walls. Since the Renaissance plaster has been very widely used for indoor ornamental work such as and ceilings, but in the 16th century it was used for large figures (many also using high relief) at the Chateau of Fontainebleau, which were imitated more crudely elsewhere, for example in the Elizabethan Hardwick Hall.
Shallow-relief, in Italian rilievo stiacciato or rilievo schicciato ("squashed relief"), is a very shallow relief, which merges into engraving in places, and can be hard to read in photographs. It is often used for the background areas of compositions with the main elements in low-relief, but its use over a whole (usually rather small) piece was effectively invented and perfected by the Italian Renaissance sculptor Donatello.Avery, vi
In later Western art, until a 20th-century revival, low relief was used mostly for smaller works or combined with higher relief to convey a sense of distance, or to give depth to the composition, especially for scenes with many figures and a landscape or architectural background, in the same way that lighter colours are used for the same purpose in painting. Thus figures in the foreground are sculpted in high-relief, those in the background in low-relief. Low relief may use any medium or technique of sculpture, stone carving and metal casting being most common. Large architectural compositions all in low relief saw a revival in the 20th century, being popular on buildings in Art Deco and related styles, which borrowed from the ancient low reliefs now available in museums.Avery, vii Some sculptors, including Eric Gill, have adopted the "squashed" depth of low relief in works that are actually free-standing.
Mid-relief is probably the most common type of relief found in the Hindu art and Buddhist art of India and Southeast Asia. The low to mid-reliefs of 2nd-century BCE to 6th-century CE Ajanta Caves and 5th- to 10th-century Ellora Caves in India are rock reliefs. Most of these reliefs are used to narrate sacred scriptures, such as the 1,460 panels of the 9th-century Borobudur temple in Central Java, Indonesia, narrating the Jataka tales or lives of the Buddha. Other examples are low reliefs narrating the Ramayana Hindu epic in Prambanan temple, also in Java, in Cambodia, the temples of Angkor, with scenes including the Samudra manthan or "Churning the Ocean of Milk" at the 12th-century Angkor Wat, and reliefs of apsaras. At Bayon temple in Angkor Thom there are scenes of daily life in the Khmer Empire.
Most of the many grand figure reliefs in Ancient Greek sculpture used a very "high" version of high relief, with elements often fully free of the background, and parts of figures crossing over each other to indicate depth. The metopes of the Parthenon have largely lost their fully rounded elements, except for heads, showing the advantages of relief in terms of durability. High relief has remained the dominant form for reliefs with figures in Western sculpture, also being common in Indian temple sculpture. Smaller Greek sculptures such as private tombs, and smaller decorative areas such as friezes on large buildings, more often used low relief.
Hellenistic and Roman sarcophagus reliefs were cut with a drill rather than , enabling and encouraging compositions extremely crowded with figures, like the Ludovisi Battle sarcophagus (250–260 CE). These are also seen in the enormous strips of reliefs that wound around Roman . The Sarcophagus in particular exerted a huge influence on later Western sculpture. The European Middle Ages tended to use high relief for all purposes in stone, though like Ancient Roman sculpture, their reliefs were typically not as high as in Ancient Greece.Avery, ii and iii Very high relief re-emerged in the Renaissance, and was especially used in wall-mounted funerary art and later on Neoclassical and public monuments.
In the Buddhist and Hindu art of India and Southeast Asia, high relief can also be found, although it is not as common as low to mid-reliefs. Famous examples of Indian high reliefs can be found at the Khajuraho temples, with voluptuous, twisting figures that often illustrate the erotic Kamasutra positions. In the 9th-century Prambanan temple, Central Java, high reliefs of Lokapala , the guardians of deities of the directions, are found.
The largest high relief sculpture in the world is the Stone Mountain Confederate Memorial in the U.S. state of Georgia, which was cut 42 feet deep into the mountain, and measures 90 feet in height, 190 feet in width, and lies 400 feet above the ground.
The technique is most successful with strong sunlight to emphasise the outlines and forms by shadow, as no attempt was made to soften the edge of the sunk area, leaving a face at a right-angle to the surface all around it. Some reliefs, especially funerary monuments with heads or busts from ancient Rome and later Western art, leave a "frame" at the original level around the edge of the relief, or place a head in a hemispherical recess in the block (see Roman example in gallery). Though essentially very similar to Egyptian sunk relief, but with a background space at the lower level around the figure, the term would not normally be used of such works.
It is also used for carving letters (typically om mani padme hum) in the of Tibetan Buddhism.
A few very late Hellenistic monumental carvings in Egypt use full "negative" modelling as though on a gem seal, perhaps as sculptors trained in the Greek tradition attempted to use traditional Egyptian conventions.Barasch, Moshe, Visual Syncretism: A Case Study, pp. 39–43 in Budick, Stanford & Iser, Wolfgang, eds., The Translatability of cultures: figurations of the space between, Stanford University Press, 1996, ().
Various modelling techniques are used, such repoussé ("pushed-back") in metalwork, where a thin metal plate is shaped from behind using various metal or wood punches, producing a relief image. Casting has also been widely used in bronze and other metals. Casting and repoussé are often used in concert in to speed up production and add greater detail to the final relief. In stone, as well as engraved gems, larger hardstone carvings in semi-precious stones have been highly prestigious since ancient times in many Eurasian cultures. Reliefs in wax were produced at least from the Renaissance.
Ivory carving reliefs have been used since ancient times, and because the material, though expensive, cannot usually be reused, they have a relatively high survival rate, and for example represent a large proportion of the survivals of portable secular art from Late Antiquity. In the Gothic art the carving of ivory reliefs became a considerable Luxury goods industry in Paris and other centres. As well as small and with densely packed religious scenes, usually from the New Testament, secular objects, usually in a lower relief, were also produced.
These were often round mirror-cases, combs, handles, and other small items, but included a few larger caskets like the Casket with Scenes of Romances (Walters 71264) in Baltimore, Maryland, in the United States. Originally they were very often painted in bright colours. Reliefs can be impressed by stamps onto clay, or the clay pressed into a mould bearing the design, as was usual with the mass-produced terra sigillata of Ancient Roman pottery. Decorative reliefs in plaster or stucco may be much larger; this form of architectural decoration is found in many styles of interiors in the post-Renaissance West, and in Islamic architecture.
In particular low reliefs were often used in the 20th century on the outsides of buildings, where they are relatively easy to incorporate into the architecture as decorative highlights.
