Rock art is an archaeological term used to refer to human-made markings placed on natural stone; it is also largely synonymous with parietal art. A global phenomenon, rock art is found in many different regions of the world, having been produced in many different contexts throughout human history, although the majority of rock art that has been ethnographically recorded has been produced as a part of ritual. Such artworks are often divided into three forms: petroglyphs which are carved into the rock surface, pictographs which are painted onto the surface, and earth figures engraved into the ground.
The oldest known rock art dates from the Upper Palaeolithic period, having been found in Europe, Australasia and Africa. Archaeologists studying these artworks believe that they likely had magico-religious significance.
The archaeological sub-discipline of rock art studies first developed in the late-19th century among Francophone scholars studying the Upper Palaeolithic rock art found in the cave systems of Western Europe. Rock art also continues to be of importance to indigenous peoples in various parts of the world, who view them as both sacred items and significant components of their cultural patrimony. Such archaeological sites are also significant sources of cultural tourism, and have been utilised in popular culture for their aesthetic qualities.
The term rock art appears in the published literature as early as the 1940s. It has also been described as "rock carvings", "rock drawings", "rock engravings", "rock inscriptions", "rock paintings", "rock pictures", "rock records" "rock sculptures.,
The defining characteristic of rock art is the fact that it is placed on natural rock surfaces; in this way it is distinct from artworks placed on constructed walls or free-standing sculpture. As such, rock art is a form of landscape art, and includes designs that have been placed on boulder and cliff faces, cave walls and ceilings, and on the ground surface. Rock art is a global phenomenon, being found in many different regions of the world.
There are various different forms of rock art. This includes pictographs, which were painted or drawn onto the panel (rock surface), petroglyphs, which were carved or engraved onto the panel, and earth figures such as earthforms, intaglios and geoglyphs. Some archaeologists also consider pits and grooves in the rock, known as cups, rings or cupules, as a form of rock art.
Although there are some exceptions, the majority of rock art whose creation was ethnographically recorded had been produced during rituals. As such, the study of rock art is a component of the archaeology of religion.
Rock art serves multiple purposes in the contemporary world. In several regions, it remains spiritually important to indigenous peoples, who view it as a significant component of their cultural patrimony. It also serves as an important source of cultural tourism, and hence economic revenue, in certain parts of the world. As such, images taken from cave art have appeared on memorabilia and other artefacts sold as a part of the tourist industry.
Pictographs are paintings or drawings that have been placed onto the rock face. Such artworks have typically been made with mineral earths and other natural compounds, which are found across much of the world, with the predominantly used colours are red, black and white. Red paint is usually attained through the use of ground ochre, while black paint is typically composed of charcoal,or sometimes from minerals like manganese instead. White paint is usually created from natural chalk, kaolinite clay or diatomaceous earth. Once the pigments had been obtained, they would have to be ground and mixed with a liquid, such as water, blood, urine, or egg yolk, and then applied to the stone as paint using a brush, fingers, or a stamp. Alternately, the pigment could have been applied on dry, such as with a stick of charcoal. In some societies, the paint itself has symbolic and religious meaning; for instance, among hunter-gatherer groups in California, paint was only allowed to be traded by the group shamans, while in other parts of North America, the word for “paint” was the same as the word for "supernatural spirit".
One unusual form of pictograph, found in many, although not all rock-art producing cultures, is the hand print. There are three forms of this; the first involves covering the hand in wet paint and them applying it to the rock. The second involves a design being painted onto the hand, which is then in turn added to the surface. The third involves the hand first being placed against the panel, with dry paint then being blown onto it through a tube, in a process that is akin to air-brush or spray-painting. The resulting image is a negative print of the hand, and is sometimes described as a "stencil" in Australian archaeology.
Petroglyphs are engravings or carvings into the rock panel. They are created with the use of a hard hammerstone which is battered against the stone surface; in certain societies, the choice of hammerstone itself has religious significance. In other instances, the rock art is pecked out through indirect percussion, as a second rock is used like a chisel between the hammerstone and the panel. A third, rarer form of engraving rock art was through incision, or scratching, into the surface of the stone with a lithic flake or metal blade. The motifs produced using this technique are fine-lined and often difficult to see.
Earth Figures 
Earth figures are large designs and motifs that are created on the stone ground surface. They can be classified through their method of manufacture. Intaglios are created by scraping away the desert pavements (pebbles covering the ground) to reveal a negative image on the bedrock below. The best known example of such intaglio rock art is the Nazca Lines of Peru. In contrast, geoglyphs are positive images,being created by piling up rocks on the ground surface to create a visible motif or design.
Motifs and panels 
Traditionally, individual markings are called motifs and groups of motifs are known as panels. Sequences of panels are treated as archaeological sites. This method of classifying rock art however has become less popular as the structure imposed is unlikely to have had any relevance to the art's creators. Even the word 'art' carries with it many modern prejudices about the purpose of the features.
Rock art can be found across a wide geographical and temporal spread of cultures perhaps to mark territory, to record historical events or stories or to help enact rituals. Some art seems to depict real events whilst many other examples are apparently entirely abstract.
Prehistoric rock depictions were not purely descriptive, with each motif and design having a "deep significance" that is not always understandable to modern scholars.
Ritual uses 
In many instances, the creation of rock art was itself a ritual act.
Relation to shamanism 
Some rock art has been interpreted to represent presumed cultural behaviors. Common features in rock art that are related to portraying shamans were bones and other skeletal remains on their coats. One reason for the bones would be that they were used as a type of armor for protecting the shaman on his journeys through different worlds. Devlet, the author of "Rock Art and the Material Culture of Siberian and Central Asian Shamanism" highlights, “Another interpretation of these skeletal costume elements explains them as representations of a shaman brought back to life after the dismemberment that occurs during the initiation process: the depicted bones thus refer to the wearer’s own skeleton” (43). The concept of death and revival is often associated with shamans and the way they are portrayed. The bones were usually on the back of the shaman’s jacket or used on the breast-piece.
Another important aspect used to distinguish shamans in rock art depictions is that they are wearing fringed fabric. There are differences in the lengths of the fringe and where on the shaman the fringe is located. In the rock art, the fringe was usually long single strands attached to different parts of the shaman’s body. The symbolism of the fringe can be interpreted in several ways. One example is, “The fringe on a shaman’s coat is an important element, which marks his or her ornithomorphic nature (i.e. the ability to transform into a bird or to gain its abilities such as the capacity for flight) ” (Devlet 44). The concept of fringe being correlated with flying was mainly used in rock art in the Altai, Tuva, and Mongolian regions.
A more mainstream characteristic is the detection of the shaman’s ritualistic drum. Even though there are different types, shapes, and images painted on the shaman’s drum, it is clearly depicted in the rock art. The range of decoration used on the drums varied from simplistic to innately elaborate. The resemblance is remarkably illustrated, “In the Altai region, images depicted on historical shamanic drums demonstrate a striking similarity with what is shown on the rock engravings” (Devlet 47).
Regional variations 
In the Upper Palaeolithic of Europe, rock art was produced inside cave systems by the hunter-gatherer peoples who inhabited the continent. The oldest known example is the Chauvet Cave in France, although others have been located, including Lascaux in France, Alta Mira in Spain and Creswell Crags in Britain.
The late prehistoric rock art of Europe has been divided into three regions by archaeologists. In Atlantic Europe, the coastal seaboard on the west of the continent, which stretches from Iberia up through France and encompasses the British Isles, a variety of different rock arts were produced from the Neolithic through to the Late Bronze Age. A second area of the continent to contain a significant rock art tradition was that of Alpine Europe, with the majority of artworks being clustered in the southern slopes of the mountainous region, in what is now south-eastern France and northern Italy.

- The Naj Tunich site is a rich rock-art site in Guatemala.
- The Rock Paintings of Sierra de San Francisco is the name given to prehistoric rock art found in the Sierra de San Francisco region of Baja California, Mexico, created by a people referred to as Cochimi or Guachimis. There are about 250 sites which are located in the municipality of Mulegé within the El Vizcaino Biosphere Reserve in the state of Baja California Sur in Northern Mexico. Motifs include human figures, weapons, and animal species such as rabbit, puma, lynx, deer, wild goat/sheep, whale, turtle, tuna, sardine, octopus, eagle, and pelican; there are also abstract elements of various forms. The paintings vary in age from 1100 BC to AD 1300. The paintings are noted for their high quality, extent, the variety and originality of human and animal representations, remarkable colors, and excellent state of preservation. The rock paintings of Sierra de San Francisco were nominated in 1989 and became a World Heritage Site in 1993.

The earliest evidence of painting derives from archaeological sites in two rock-shelters in Arnhem Land, in northern Australia. In the lowest layer of material at these sites there are used pieces of ochre estimated to be 60,000 years old. Archaeologists have also found a fragment of rock painting preserved in a limestone rock-shelter in the Kimberley region of North-Western Australia dated at 40 000 years old. In 2008, rock art depicting what is thought to be a Thylacoleo was discovered on the north-western coast of the Kimberley. Thylacoleo is believed to have gone extinct by 46,000 years ago. Pigments from the "Bradshaw paintings" of the Kimberley are so old they have become part of the rock itself, making carbon dating impossible. Some experts suggest that these paintings are in the vicinity of 50,000 years old and may even pre-date aboriginal settlement.
- Kakadu National Park in the Northern Territory has a large collection of ochre paintings. Ochre is a not an organic material, so carbon dating of these pictures is impossible. Sometimes the approximate date, or at least, an epoch, can be guessed from the content.
- Important rock engravings can be found in the Sydney region.
- Mount Grenfell Historic Site near Cobar, western New South Wales also has important ancient rock drawings.
- The Murujuga (Burrup Peninsula) area of Western Australia near Karratha is estimated to be home to between 500,000 and 1 million individual engravings.
Rock Art Studies 
The archaeological sub-discipline devoted to the investigation of rock art is known as "rock art studies." Rock art specialist David S. Whitley noted that research in this area required an "integrated effort" that brings together archaeological theory, method, fieldwork, analytical techniques and interpretation.
Although French archaeologists had undertaken much research into rock art, Anglophone archaeology had largely neglected the subject for decades.
The discipline of rock art studies witnessed what Whitley called a "revolution" during the 1980s and 1990s, as increasing numbers of archaeologists operating in the Anglophone world and in Latin America turned their attention to the subject. In doing so, they recognised that rock art could be used to understand symbolic and religious systems, gender relations, cultural boundaries, cultural change and the origins of art and belief. One of the most significant figures in this movement was the South African archaeologist David Lewis-Williams, who published his studies of San rock art from southern Africa, in which he combined ethnographic data to reveal the original purpose of the artworks. Lewis-Williams would come to be praised for elevating rock art studies to a "theoretically sophisticated research domain" by Whitley.
