Rock engravings, also known as petroglyphs, are images or symbols carved into rock surfaces by ancient peoples. These engravings can be found worldwide and often depict animals, human figures, or abstract designs. They serve as a form of communication, storytelling, or spiritual expression, providing insight into the cultures that created them. The techniques used for rock engraving vary, but they typically involve tools like chisels or hammers to remove the rock surface. Many rock engravings are found in locations such as caves, cliffs, and rock shelters, where they have been preserved over time, allowing researchers to study the history and beliefs of early civilizations.
