Petroglyphs are images created by removing part of a rock surface by incising, picking, carving, or abrading, as a form of rock art. Outside North America, scholars often use terms such as "carving", "engraving", or other descriptions of the technique to refer to such images. Petroglyphs are found worldwide, and are often associated with prehistoric peoples. The word comes from the Greek word petro-, theme of the word "petra" meaning "stone", and glyphein meaning "to carve", and was originally coined in French as pétroglyphe.
The term petroglyph should not be confused with petrograph, which is an image drawn or painted on a rock face. Both types of image belong to the wider and more general category of rock art or parietal art. Petroforms, or patterns and shapes made by many large rocks and boulders over the ground, are also quite different. Inukshuks are also unique, and found only in the Arctic (except for reproductions and imitations built in more southerly latitudes).
Another form of petroglyph, normally found in literate cultures, a rock relief or rock-cut relief is a relief sculpture carved on "living rock" such as a cliff, rather than a detached piece of stone. While these relief carvings are a category of rock art, sometimes found in conjunction with rock-cut architecture,they tend to be omitted in most works on rock art, which concentrate on engravings and paintings by prehistoric or nonliterate cultures. Some of these reliefs exploit the rock's natural properties to define an image. Rock reliefs have been made in many cultures, especially in the Ancient Near East. Rock reliefs are generally fairly large, as they need to be to make an impact in the open air. Most have figures that are larger than life-size.
Stylistically, a culture's rock relief carvings relate to other types of sculpture from period concerned. Except for Hittite and Persian examples, they are generally discussed as part of the culture's sculptural practice. The vertical relief is most common, but reliefs on essentially horizontal surfaces are also found. The term relief typically excludes relief carvings inside natural or human-made caves, that are common in India. Natural rock formations made into statues or other sculpture in the round, most famously at the Great Sphinx of Giza, are also usually excluded. Reliefs on large boulders left in their natural location, like the Hittite İmamkullu relief, are likely to be included, but smaller boulders described as stele or carved orthostats.

Some petroglyphs might be as old as 40,000s, and petroglyph sites in Australia are estimated to date back 27,000 years. Many petroglyphs are dated to approximately the Neolithic and late Upper Paleolithic boundary, about 10,000 to 12,000 years ago, if not earlier, such as Kamyana Mohyla. Around 7,000 to 9,000 years ago, other precursors of writing systems, such as pictographs and ideograms, began to appear. Petroglyphs were still common though, and some cultures continued using them much longer, even until contact with Western culture was made in the 19th and 20th centuries. Petroglyphs have been found in all parts of the globe except Antarctica, with highest concentrations in parts of Africa, Scandinavia, Siberia, southwestern North America, and Australia.
Many hypotheses explain the purpose of petroglyphs, depending on their location, age, and subject matter. Some many be astronomical markers, maps, and other forms of symbolic communication, including a form of proto-writing. Petroglyph maps may show trails, symbols communicating time and distances traveled, as well as the local terrain in the form of rivers, landforms, and other geographic features. A petroglyph that represents a landform or the surrounding terrain is known as a geocontourglyph. They might also have been a by-product of other rituals: sites in India, for example, have been identified as musical instruments or "rock gongs".
Some petroglyph images probably have deep cultural and religious significance for the societies that created them; in many cases this significance remains for their descendants. Many petroglyphs are thought to represent some kind of not-yet-fully understood symbolic or ritual language. Later glyphs from the Nordic Bronze Age in Scandinavia seem to refer to some form of territorial boundary between tribes, in addition to possible religious meanings. Petroglyph styles has local or regional "dialects" from similar or neighboring peoples. Siberian inscriptions loosely resemble an early form of runes, although no direct relationship has been established. They are not yet well understood.
Petrogylphs from different continents show similarities. While people would be inspired by their direct surroundings, it is harder to explain the common styles. This could be mere coincidence, an indication that certain groups of people migrated widely from some initial common area, or indication of a common origin. In 1853, George Tate presented a paper to the Berwick Naturalists' Club, at which a John Collingwood Bruce agreed that the carvings had "... a common origin, and indicate a symbolic meaning, representing some popular thought." In his cataloguing of Scottish rock art, Ronald Morris summarized 104 different theories on their interpretation.
More controversial explanations of similarities are grounded in Jungian psychology and the views of Mircea Eliade. According to these theories it is possible that the similarity of petroglyphs (and other atavistic or archetypal symbols) from different cultures and continents is a result of the genetically inherited structure of the human brain.
Other theories suggest that petroglyphs were carved by spiritual leaders, such as shamans, in an altered state of consciousness, perhaps induced by the use of natural hallucinogens. Many of the geometric patterns (known as form constants) which recur in petroglyphs and cave paintings have been shown by David Lewis-Williams to be hardwired into the human brain. They frequently occur in visual disturbances and hallucinations brought on by drugs, migraine, and other stimuli.
Recent analysis of surveyed and GPS-logged petroglyphs around the world has identified commonalities indicating pre-historic (7,000–3,000 BCE) intense auroras, or natural light display in the sky, observable across the continents.
The Rock Art Research Institute (RARI) of the University of the Witwatersrand studies present-day links between religion and rock art among the San people of the Kalahari Desert. Though the San people's artworks are predominantly paintings, the beliefs behind them can perhaps be used as a basis for understanding other types of rock art, including petroglyphs. To quote from the RARI website:
Using knowledge of San beliefs, researchers have shown that the art played a fundamental part in the religious lives of its San painters. The art captured things from the San's world behind the rock-face: the other world inhabited by spirit creatures, to which dancers could travel in animal form, and where people of ecstasy could draw power and bring it back for healing, rain-making and capturing the game.
List of petroglyph sites
- Bambari, Lengo and Bangassou in the south; Bwale in the west
- Djebel Mela
- The Niari Valley, 250 km south west of Brazzaville
- Wadi Hammamat in Qift, many carvings and inscriptions dating from before the earliest Egyptian Dynasties to the modern era, including the only painted petroglyph known from the Eastern Desert and drawings of Egyptian reed boats dated to 4000 BCE
- Inscription Rock in South Sinai, is a large rock with carvings and writings ranging from Nabatean to Latin, Ancient Greek and Crusder eras located a few miles from the Ain Hudra Oasis. A second rock sites approximately 1 km from the main rock near the Nabatean tombs of Nawamis with carvings of animals including Camels, Gazelles and others. The original archaeologists who investigated these in the 1800s have also left their names carved on this rock.
- Giraffe petroglyphs found in the region of Gebel el-Silsila. The rock faces have been used for extensive quarrying of materials for temple building especially during the period specified as the New Kingdom. The Giraffe depictions are located near a stela of the king Amenhotep IV. The images are not dated, but they are probably dated from the Predynastic periods.

This is the second instance when a dolmen with petrographs has been found in Tamil Nadu, India.
During recent years a large number of rock carvings has been identified in different parts of Iran. The vast majority depict the ibex. Rock drawings were found in December 2016 near Khomeyn, Iran, which may be the oldest drawings discovered, with one cluster possibly 40,000 years old. Accurate estimations were unavailable due to US sanctions.
Petroglyphs are the most ancient works of art left by humankind that secretly provide an opening to the past eras of life and help us to discover different aspects of prehistoric lives. Tools to create petroglyphs can be classified by the age and the historical era; they could be flint, thighbone of hunted quarries, or metallic tools. The oldest pictographs in Iran are seen in Yafteh cave in Lorestan that date back 40,000 and the oldest petroglyph discovered belongs to Timareh dating back to 40,800 years ago.
Iran provides exclusive demonstrations of script formation from pictogram, ideogram, linear (2300 BC) or proto Elamite, geometric old Elamite script, Pahlevi script, Arabic script (906 years ago), Kufi script, and Farsi script back to at least 250 years ago. More than 50000 petroglyphs have been discovered, extended over all Iran's states.
One of the characteristics of Iran’s petroglyphs is the continuity of existence of prehistoric marks on the ancient pottery and bronze sculptures that reveal the impressiveness of petroglyphs of the facades of caves and rocks reflected on ancient work of arts.
This continuity can be traced from eighth millennium BCE by the potteries in Ganj Darreh near Harseen in Kermanshah state, to third and first millennium BCE, considering the bronze period in Lorestan. There is a unique similarity between petroglyph marks and prehistoric potteries as if all these works are done by a sole artist.
