The world's oldest ritual site
In a small, secluded cave in Botswana's Tsodilo Hills, a massive rock formation evokes the head of a giant python. The rock, measuring six meters long and two meters high, is covered in 300 to 400 man-made indentations that resemble scales. In firelight, the indentations create the illusion that the snake is moving. This cave, known as Rhino Cave, contains evidence of ritualistic behavior dating back 70,000 years, making it arguably the oldest known site of human ritual in the world.
The discovery was made by a team led by Associate Professor Sheila Coulson from the University of Oslo. Excavations directly in front of the python rock unearthed more than 13,000 artifacts. The assemblage consisted entirely of stone spearheads and the tools used to make them; no signs of ordinary habitation were found. The spearheads are unusually elaborate and colorful, crafted from stone that must have been transported from hundreds of kilometers away. A significant number of the spearheads, specifically the red ones, were intentionally burned in a fire hot enough to damage them beyond use. This ritual destruction of valuable objects points to a complex and organized belief system among Homo sapiens much earlier than previously thought.
The cave is named for a prominent white painting of a rhinoceros on one of its walls, but the central focus of the ancient activity was the python rock. The site's location within the Tsodilo Hills is significant. The hills, a UNESCO World Heritage Site, are a sacred place for the San people, who call them the "Mountains of the Gods."
The python in San mythology
The python is one of the most important animals in San cosmology. According to their creation myth, humanity is descended from the python. The arid, ancient streambeds surrounding the Tsodilo Hills are said to have been created by the giant snake as it searched for water. This deep cultural connection suggests that the rituals performed in the cave 70,000 years ago may be linked to the beliefs still held by San people living in the region today.
Inside the cave, archaeologists found only two paintings near the python rock: one of an elephant and one of a giraffe. These are also important animals in San mythology, often linked to the python. The elephant, with its trunk, can be a metaphor for the python. The site's focus on these specific animals, combined with the ritualistic destruction of artifacts, shows the abstract thought and spiritual life of people in the Middle Stone Age.
Adding another layer to the site's function, researchers discovered a small, secret chamber behind the main python rock. Parts of the entrance are worn smooth, suggesting many people passed through it over time. A shaman could have hidden in this chamber, their voice appearing to emanate directly from the stone python, creating a powerful effect during ceremonies. The entire arrangement—the carved rock, the burned offerings, and the hidden chamber—points to a sophisticated ritual practice centered on this powerful animal spirit.
