What are Petroglyphs?

About Petroglyphs:

• Petroglyphs (also known as rock engravings) are symbolic images sculpted or engraved on the surface of rocks by removing material from its surface layer with instruments of superior hardness.
• The word ‘’petroglyph’’ is derived from two Greek words, ‘’petros’’ meaning “stone,” and ‘’glyphein’’ meaning “to carve.“
• The techniques used to create these images include pecking, incising, abrading, sculpting, polishing, drilling, and scratching.
• These processes remove part of the rock and therefore are different from images simply painted or drawn on rock, which are called petrographs.
• Because petroglyphs are carved into rock, they tend to last longer than petrographs.
• Petroglyphs took two primary forms, as images either appear as scratches or deeper visible indentations on rock.
• Petroglyphs are typically associated with prehistoric populations. These carvings often depict animals, people, geometric shapes, and symbolic images that offer insights into the social and religious lives of ancient peoples.
• They can be found on every continent throughout the world, except Antarctica.
  • However, they are especially concentrated in Africa, South America, North America (mainly in the southwestern United States), Siberia, Australia, and Europe (Scandinavia, Spanish Galicia, Ireland, and Italy).
• Example of Petroglyph Site in India: Edakkal Caves in Wayanad, Kerala.
• Significance:
  • They are among the earliest forms of art to have existed and are therefore considered the foundation of art.
  • Ancient peoples also used petroglyphs as a form of communication or writing.
  • For example, some petroglyphs clearly indicated the borders between tribal lands, and others were astronomical markers and maps.
  • Additionally, some petroglyphs served as musical instruments and were known as “rock gongs.”
