Nearly 68,000 years ago, someone pressed their hand against a cave wall and blew red pigment over it, leaving a trace that said, "I was here." Over 40,000 years older than Lascaux, this is humanity's oldest known artwork, and it wasn't found in Europe but in a small Indonesian island cave. The discovery is rewriting the story of human artistic evolution and illuminating the ancient paths our ancestors took to reach Australia.

The World's Oldest Cave Art: Found on Indonesia's Muna Island

On January 22, 2026, a paper published in the journal Nature sent shockwaves through the archaeological community. A hand stencil found in the Liang Metanduno cave on Muna Island, in southeastern Sulawesi, Indonesia, has been confirmed as at least 67,800 years old, making it the oldest reliably dated cave art in the world.

The stencil surpasses what was previously considered the oldest cave art: hand markings in a Spanish cave attributed to Neanderthals, by more than 1,000 years. It is also over 16,000 years older than the earliest rock art previously documented in southwestern Sulawesi's Maros-Pangkep region by the same research team.

The study was led by Adhi Agus Oktaviana of Indonesia's National Research and Innovation Agency (BRIN) and Maxime Aubert, a specialist in archaeological science at Griffith University in Australia, along with an international team of researchers.

How Uranium-Series Dating Unlocks the Age of Ancient Art

The key to this breakthrough is a cutting-edge technique called laser-ablation uranium-series dating (LA-U-series dating).

Cave paintings cannot be dated using conventional radiocarbon methods because the pigments are not organic materials. Instead, researchers focus on the thin layers of calcium carbonate (calcite) that naturally form over cave paintings over thousands of years. These mineral deposits contain trace amounts of uranium, which decays into thorium at a known, constant rate. By precisely measuring the ratio of uranium-234 to thorium-230, scientists can determine when the calcite layer formed.

The LA-U-series method represents a significant advancement over older solution-based uranium-series techniques. Rather than physically scraping off calcite and dissolving it for analysis, this approach uses a finely focused laser (with a spot diameter of approximately 44 micrometers) to analyze polished cross-sections of the mineral deposits non-destructively. This allows researchers to target the calcite closest to the pigment layer, dramatically improving accuracy and avoiding the systematic underestimation of ages that plagued earlier methods.

Importantly, the dates obtained through this method represent minimum ages. Since there may be a time lag between when the painting was created and when the first calcite layer formed over it, the actual age of the artwork could be even older. The 67,800-year figure is a floor, not a ceiling.

What the Hand Stencil Reveals: More Than a Simple Handprint

The Muna Island hand stencil measures approximately 14 centimeters by 10 centimeters and was created by placing a hand against the cave wall and blowing red pigment, likely ochre, over it. While the stencil has faded considerably and its preservation is deteriorating, researchers noted a remarkable detail: the fingertips of one hand were deliberately modified to appear pointed, like animal claws.

This technique of reshaping fingertips is unique to Sulawesi, found nowhere else in the prehistoric record. According to Adam Brumm, an archaeologist at Griffith University, the artists may have been trying to transform the human handprint into something else entirely, perhaps an animal or a mythical being. This suggests that these early humans already possessed the cognitive sophistication to use their imagination to alter reality in creative ways.

Combined with the team's 2024 discovery of a 51,200-year-old narrative cave painting in Sulawesi (depicting human-like figures interacting with a wild pig), the Muna find strengthens the case that a sustained, sophisticated artistic culture existed in Indonesia during the Late Pleistocene epoch.

Overturning the "Europe First" Theory of Art

For much of the 20th century, the prevailing view in archaeology was that advanced artistic expression first emerged when humans arrived in Europe. The famous cave paintings of Lascaux in France (roughly 20,000 years old) and Altamira in Spain were long considered humanity's earliest creative masterpieces.

The series of discoveries in Sulawesi since 2014 has systematically dismantled this Eurocentric framework. Figurative art dating back over 40,000 years, narrative scenes from more than 51,000 years ago, and now a hand stencil from approximately 68,000 years ago, all found in Indonesia, all far older than Europe's celebrated cave paintings.

These findings suggest one of two possibilities: either artistic expression originated independently in multiple regions, including Southeast Asia, or, perhaps more likely, humans who left Africa already carried the capacity for symbolic thought and creative expression with them. The "cognitive revolution" that produced art may have occurred before the great migration out of Africa, rather than in Europe as traditionally assumed.

Illuminating the Path to Australia

The discovery carries profound implications for another great archaeological puzzle: how early humans first reached Australia.

Modern humans (Homo sapiens) are believed to have arrived in Australia, then connected to Papua New Guinea as part of the landmass called Sahul, approximately 65,000 years ago. But the route they took has been hotly debated.

The "northern route" hypothesis proposes that people traveled from Borneo through the islands of eastern Indonesia, including Sulawesi, then crossed to Papua New Guinea by boat and walked into Sahul. The "southern route" hypothesis suggests a path through Java, Bali, the Lesser Sunda Islands, and Timor, followed by a sea crossing to northwestern Australia.

Finding 67,800-year-old art on Muna Island, located off the southeastern coast of Sulawesi, provides the first direct evidence that modern humans were present on these Indonesian islands at that time. According to Aubert, the discovery "probably supports the hypothesis of arriving in Australia via Papua New Guinea around 65,000 years ago via the northern route," though the southern route cannot be entirely ruled out.

The research team believes the artists were likely closely related to the ancestors of Australia's Aboriginal peoples, making this hand stencil a tangible connection between Indonesia's prehistoric cave painters and one of the world's oldest continuous cultures.

Sulawesi's Caves: An Exploration Still in Its Infancy

The current study surveyed 44 cave sites in southeastern Sulawesi, dating 11 rock art motifs including seven hand stencils. Fourteen of these sites were previously unknown to archaeologists.

Liang Metanduno itself contains over 400 paintings beyond the ancient hand stencil, including images of people on horseback, birds, and other figures estimated to be approximately 3,500 to 4,000 years old. This means the same cave was used as a canvas repeatedly over at least 35,000 years.

Sulawesi's karst landscape contains countless limestone caves, and rock art has been documented at 242 sites so far. Many of these remain uninvestigated with modern dating techniques. The potential for discovering even older art is very real.

The Race Against Deterioration

Despite their immense cultural significance, many of these cave paintings face serious threats. The Muna hand stencil itself is visibly fading, and researchers are concerned about its long-term preservation. Industrial activity has already destroyed some caves in the region, and climate change is altering the delicate microenvironments within the caverns that have protected the art for tens of thousands of years.

The research team hopes that the global attention brought by this discovery will boost conservation efforts. How we choose to protect a 68,000-year-old message from our ancestors may itself become a defining chapter in humanity's cultural legacy.

This discovery has sparked widespread fascination in Japan, with many people expressing awe that artistic expression existed over 60,000 years ago and noting how it overturns Eurocentric assumptions about the origins of art. What are the perspectives in your country on the origins of human creativity? Does your homeland have ancient rock art or cave paintings of its own? We'd love to hear your thoughts on what "art" meant to our earliest ancestors, and what it means to you today.
