He cracked a code hidden for millennia in ancient cave paintings—here’s what it reveals

Imagine decoding a message left behind by our ancestors 40,000 years ago—armed with nothing more than curiosity, a keen eye, and a regular day job! Bennett Bacon, a humble furniture conservator from London, might just have done it, and this unexpected twist is sending shockwaves through the world of archaeology.

The Spark of Discovery: A Furniture Conservator Meets Cave Art

Bennett Bacon isn’t your usual suspect for headline-making archaeological discoveries. Based in London and working as a simple furniture conservator, his path to academic glory took a wildly unconventional route. In January 2023, Bacon found himself at the heart of a scientific publication in the Cambridge Archaeological Journal. But how did he end up here?

Everything began one ordinary day as Bacon scrolled through images of prehistoric European cave paintings dating from 15,000 to 40,000 years ago—a little Paleolithic hobby for the modern mind. Among hundreds of photos, he started to notice something curious. There, etched near the animals in these ancient masterpieces, were small lines and dots. To the untrained eye, easily dismissed. To Bacon? A tantalizing mystery asking to be cracked.

A Code Hidden in Plain Sight

These patterns—tiny strokes and points—kept appearing beside animals over and over. Bacon pondered: could these not just be random decorations, but humanity’s earliest writing? His attention was piqued by a striking consistency; the number of lines and dots never exceeded thirteen. This peculiar limitation led him to his first hypothesis: these might be temporal markers, possibly based on the moon’s cycle. Yes, he dared imagine Europe’s first lunar calendars painted in ochre and bone-black.

Driven by relentless curiosity, Bacon went full detective. As he explained (according to Sci News), he had always been intrigued by the meaning of these marks. To try to decode them, he drew inspiration from the methods used to decipher ancient forms of Greek text. The comparison is delightfully bold—who says a love of antiquity should be restricted by your day job?

From Amateur to Academic: Collaboration and Debate

Having pieced together his theory, Bacon didn’t keep it under his hat. He reached out to university specialists—archaeologists well-seasoned in the puzzles of prehistory—for their insights. His aim? Clarity, but maybe also to see if the experts might back up his wild (yet evidence-based) hunch.

Here’s the twist: for well over a century, archaeologists had thought these little symbols were simply practical tallies, counting animals seen or killed during the hunt. Bacon’s theory offered something far fresher and infinitely more complex.

• He suggested these marks could denote time—perhaps critical periods for animal migration, mating, or birthing.
• The 13-mark maximum fit suspiciously well with lunar cycles, each lunar year containing just under thirteen full moons.
• Potentially, these patterns represented not annual calendars but a way to track time by seasons—a lifeline for a society so deeply dependent on nature’s rhythms.

Experts didn’t dismiss him. Quite the opposite—many recognized that humans of the Paleolithic displayed advanced knowledge of animal cycles, essential for planning survival strategies. Tony Freeth, professor at University College London, added his voice: “Lunar calendars are ‘difficult,’ because there are a bit fewer than twelve and a half lunar months in a year—they don’t fit neatly.” But they do, apparently, fit the age-old marks in European caves.

Implications for the History of Writing and Human Ingenuity

If Bacon’s hypothesis stands up to further scrutiny, it could turn our understanding of early Homo sapiens’ intellect on its head. The prevailing wisdom has long been that the invention of writing—structured, symbolic representation of information—was a late arrival in human culture. Here, with these flickers of pigment and scratched lines, may be evidence that our prehistoric relatives conceptualized time in astonishingly sophisticated ways.

The publication of Bacon’s theory in the Cambridge Archaeological Journal caught the imagination of archaeologists everywhere. Could these marks prove that Paleolithic communities possessed systems of knowledge far in advance of what was previously believed? If that is the case, they may offer an entirely new perspective on the organization, foresight, and perhaps even the artistic expressiveness of early European societies.

What started with a keen gaze and a bit of luck has become a reminder that anyone—whether armed with a PhD or a hammer and chisel—can push the boundaries of our shared story, as long as they dare to look just that little bit closer.

So, next time you find something odd in your attic, take a lesson from Bennett Bacon. Be curious, be bold—and who knows? You might just rewrite history from your own living room.
