Why Did Ancient Humans Paint Caves? What Prehistoric Art Tells Us

Why did ancient humans paint caves? Deep in caves across the world, people left handprints, animals and abstract signs that are tens of thousands of years old. Nobody can say for certain what they meant, but researchers have several ideas. This article explains what cave art is, how it was made and what the main theories suggest about the people who made it.

What Is Cave Art?

Cave art, also called rock art, includes paintings, drawings and engravings on cave walls and rock surfaces. Common subjects include large animals, human handprints and repeated dots, lines or shapes. Well-known sites exist in Europe, but rock art is found on many continents, which shows that image-making was widespread among early humans.

How Was It Made?

• Pigments: natural minerals such as iron-rich earth for reds and yellows, and charcoal for black.
• Application: fingers, simple brushes, pads of material, or blowing pigment over a hand held against the wall.
• Engraving: lines scratched or cut into the rock with stone tools.
• Lighting: deep caves are dark, so people probably used fire-based lamps or torches.

The use of red pigment is also connected to early body decoration, which we discuss in our article on red paint, seashells and the origins of clothing.

What Did the Images Show?

Many images show animals that were important to the people who lived near them. Handprints are especially striking, because they feel like a personal signature across the ages. Some images are mysterious and do not clearly represent anything we can name.
