67,800-Year-Old Hand Stencil in Indonesia Confirmed as Oldest Known Rock Art

A hand stencil discovered in a limestone cave on the island of Sulawesi, Indonesia, has been definitively dated to at least 67,800 years old, making it the oldest known example of rock art on Earth. The discovery, led by an international team of researchers from Griffith University, Indonesia’s National Research and Innovation Agency (BRIN), and Southern Cross University, pushes back the timeline of human artistic expression by at least 15,000 years.

Unveiling the Ancient Artwork

The artwork was found in Liang Metanduno cave in southeastern Sulawesi, alongside other paintings of varying ages. The hand stencil, notable for its intentionally modified, claw-like appearance, was identified as the oldest through uranium-series dating of tiny mineral layers formed over and beneath the image. ScienceDaily This dating method examines the decay of uranium to determine the age of the surrounding calcium carbonate deposits. Griffith University

Implications for Human Migration and Culture

The discovery has significant implications for understanding the history of human migration and cultural development. Researchers believe the people who created the Sulawesi art were likely ancestors of the First Australians, supporting the theory that humans reached Sahul (the combined landmass of present-day Australia, Tasmania, and Novel Guinea) at least 65,000 years ago. ScienceDaily This evidence strengthens the case for a northern migration route through Sulawesi and the Spice Islands toward New Guinea. ScienceDaily

A Long History of Artistic Expression

The research reveals that artistic activity in the Sulawesi caves spanned at least 35,000 years, continuing until around 20,000 years ago. ScienceDaily This demonstrates that Sulawesi was home to one of the world’s richest and most longstanding artistic cultures, originating in the earliest stages of human occupation on the island.

The Significance of the Claw-Like Handprint

The hand stencil’s unique claw-like shape, created by intentionally narrowing the outlines of the fingers, remains a mystery. Researchers speculate it could symbolize a connection between humans and animals, a theme already present in other early Sulawesi paintings depicting part-human, part-animal beings. ScienceDaily

Ongoing Research and Future Discoveries

The research team, supported by the Australian Research Council (ARC), Google Arts & Culture, and the National Geographic Society, continues to explore the region for further evidence of early human activity. ScienceDaily Initiatives like the ARC Centre of Excellence for Transforming Human Origins Research and the ARC Training Centre for Advancing Archaeology in the Resources Sector aim to expand our understanding of human evolution and protect cultural heritage. ScienceDaily The findings have similarly been featured in the documentary ‘Sulawesi l’île des premières images,’ produced by ARTE. ScienceDaily
