Welcome mystery lovers and antiquity detectives! Today we are going to be introduced to several ancient mysteries that have recently been solved—or have they?

A discovery two millennia in the making

For over 150 years experts have puzzled over a set of strange half-circles, found in France, and dated to the country’s Stone Age. Craftsmen crafted the first example of the ‘open rings’ from deer antlers, which was found in Le Placard Cave in southwestern France in the 1870s. Since then, researchers have uncovered 11 more. One of these was a so-called ‘preform’—a half-finished ring still attached to the antler—which was dated by researchers and found to be an enormous 21,000 years old.

Now a new study claims to have finally explained the rings’ unusual shape: they were finger grips for Paleolithic spear-throwers. A spear-thrower is a wooden shaft attached to a dart that was used for hunting large game, and the finger loop would have given the wielder extra grip and accuracy.

L’Anse aux Meadows, Newfoundland and Labrador, Canada

A discovery by a Norwegian couple in 1960 shattered the idea that Christopher Columbus was the first European to reach the Americas. L’Anse aux Meadows investigations confirm Vikings crossed the Atlantic 500 years before Columbus. Once they’d landed in America, a small community of Vikings set up camp in sturdy wooden huts—though it’s unclear whether the site functioned as a trading base or a colony. Nowadays, recreated buildings help modern visitors picture what life was like when the Vikings came to North America.

Hoxne hand axes, England, UK

When antiquarian John Frere found flint hand axes in a 12-foot hole dug by brick workers in Suffolk in 1797, he wrote to the Society of Antiquaries and ventured his belief that these axes were from a “very remote period indeed”—a controversial assertion when many still followed the Bible’s suggestion that the world was only a few thousand years old. But Frere wasn’t wrong, and modern tests proved that the hand axes date back at least 370,000 years. The flint tools are now housed in the British Museum.

Giza workers’ cemetery, Egypt

Traditional Egyptology has long held that slaves working in back-breaking conditions built the pyramids—a view propagated by the classical Greek historian, Herodotus. But an ancient cemetery uncovered at the turn of the 21st century suggests laborers able to quit at will actually built the pyramids. Those who died on the job had a respectful burial close to the tombs they built, which included jars of beer and bread for the afterlife. Not quite the riches of pharaonic burials, but these generous gifts have changed our understanding of social class in the deserts of ancient Egypt.

Gobekli Tepe, Turkey

For a long time, historians thought the Neolithic Revolution—when humans stopped being nomads and started living in permanent agricultural settlements—occurred around 10,000 years ago. That consensus lasted until the 1990s, when archaeologists working at Gobekli Tepe in southern Turkey used radiocarbon dating to pinpoint the site’s construction to 11,000 years ago, pushing the birth of human settlement further back into prehistory. Not only that, but some archaeologists working at Gobekli Tepe believe it may have been home to the world’s first temple. It’s well worth a trip to Turkey to see a monument twice the age of Stonehenge.

Now if you love solving mysteries, and you like adventures, who knows? Maybe someday you will become an archeologist and set out to explore the world and its ancient mysteries for yourself.
