Every year, we delve back through our coverage to find the most fascinating archaeological discoveries of the year, whether by a complete amateur, or as the result of years of careful study by a team of experts.
As always, archaeology news takes us around the globe and throughout the ages, from the earliest days of human history through to the contemporary era. Here are our picks for the 2021 archaeological stories worth revisiting.
The ancient circle of stone monoliths on the U.K.’s Salisbury Plain is one of history’s most enduring mysteries. But while we may never fully understand this ancient structure, experts are learning more and more about it each year.
Thanks in no small part to the late Robert Phillips, a diamond cutter who made repairs to a fallen stone at the site in 1958, we now know that the massive monoliths are made from a nearly indestructible matrix of interlocking quartz crystals—which is why the monument has stood for millennia. Phillips drilled a three-and-a-half foot core sample during his work, which he was allowed to keep as a souvenir. He returned it in 2019, allowing scientists to conduct valuable testing on the stones, which are now protected under English heritage law and cannot be sampled.
This year also saw archaeologists discover a former stone circle in Wales that closely matches the dimensions of Stonehenge’s inner ring. That suggests that the site’s inner stone circle was originally erected 175 miles away and moved to Salisbury Plain—and carbon dating shows it was built 400 years before Stonehenge proper. If this all seems too unbelievable to be true, just wait: it perfectly matches a Stonehenge legend that Merlin stole the monument and moved it to England.
Original Flavor Pompeii—and a New Version in Egypt
Do the discoveries ever seem to stop in Pompeii? A newly excavated , a kind of Roman fast food restaurant, began welcoming visitors this summer. Archaeologists were able to identify the space in part because it was decorated with frescoes featuring some popular ingredients in Pompeii cuisine, such as roosters.
Other Pompeii finds this year included an intact chariot, slaves’ quarters, and evidence of thriving Greek theater scene.
But Pompeii isn’t the only ancient city found nearly intact. In fact, a smaller “mini” Pompeii was found hidden beneath vines in Verona by construction workers. And in Egypt, another wellspring of ancient treasures, 2021 saw what’s being hailed as the nation’s most significant discovery since Howard Carter uncovered King Tut’s golden tomb nearly a century ago: the abandoned city of Luxor.
The city was a royal metropolis outside the city of Thebes built by Tutankhamun’s grandfather, King Amenhotep III. His son, Akhenaten, appears to have abandoned the city when he started a new religion worshipping only the sun god, Aten.
The Dead Sea Scroll Reveal Their Secrets
A Bedouin shepherd found the Dead Sea Scrolls in 1947. The earliest known Hebrew biblical texts, they are considered among the most significant archaeological discoveries of the 20th century. This year, scholars found new Dead Sea Scroll fragments for the first time in 60 years at a site called the Cave of Horrors.
The site was first excavated in the 1950s, and received its dark name because of what archaeologists first saw—the skeletons of Jewish men, women, and children the Romans killed during the Bar Kokhba Rebellion.
We also learned more about the scrolls thanks to science, when researchers examined the 24-foot-long Great Isiah scroll in microscopic detail. To the naked eye, the writing all looks identical, but AI pattern recognition technology was able to detect undeniable differences, demonstrating it was written by two `different scribes.
Art and Civilization Outside Europe
While archaeologists continue to learn more about some of the world’s most famous historic sites and artifacts, Asia, Africa, and North America have also yielded important discoveries that are helping shift our Eurocentric preconceptions about prehistory and early civilizations.
Archaeologists have never found human remains in Wonderwerk Cave in South Africa, but ancient humans appear to have lived there an astounding two million years ago, which would make it the world’s oldest home. Experts tested different rock laters to determine when humans entering the cave would have tracked in bedrock sediment.
The world’s oldest figurative art, meanwhile, appears to have been found on the Indonesian island of Sulawesi, where a cave painting of three wild pigs is now believed to be 45,500 years old. Made with red ochre pigment, the images are shockingly well-preserved. Scientists determined its age by testing a calcite mineral crust that had formed atop the artwork using uranium-series dating.
Meanwhile, Light Detection and Ranging (LiDAR) mapping tools have once again proved a powerful force for archaeological discovery, this time in Cambodia. The laser’s topographical readings of the area surrounding the Angkor Wat complex suggests that what is now jungle was once filled with homes built from organic materials on low-lying mounds. At its height in the 13th century, the region was likely home to nearly one million people, which would mean it was one of the world’s largest pre-modern cities.
Perhaps most intriguingly, in the Americas, our entire accepted theory about human arrival on the hemisphere looks to be in danger of being upturned thanks to human footprints discovered on a dry lake-shore in New Mexico’s White Sands National Park. Radiocarbon on the grass seeds left behind in the tracks determined that the footprints were made between 22,800 and 21,130 years ago—the oldest ever found in North America.
The find is especially significant because historians have long held that humans first made their way to North America from Asia across the Bering Land Bridge at the end of the Ice Age, around 13,500 to 13,000 years ago. But the “Clovis First” theory, the name given to those believed to be the continent’s first settlers, is now in jeopardy of being completed overturned: White Sands’ footprints are the most convincing of a number of potentially pre-Clovis discoveries that could completely change what we know about prehistory.
Redefining Gender Roles Throughout the Ages
There were several discoveries this year that prove we still have much to learn about the role of gender roles throughout human history—and how they differ from contemporary norms.
A Finnish grave had long puzzled archaeologists. The person was laid to rest with a warrior’s sword, but also with women’s jewelry. Now, genetic testing on the physical remains, dating to 1050 to 1300 A.D., has revealed that the deceased was a nonbinary person with an extra X chromosome. What makes the discovery all the more intriguing is that the burial suggests that this was a high-status person, and that their embrace of a non-standard gender identity was accepted in society.
Other discoveries this year have identified powerful women throughout the ages. Queen Cynethryth ruled Mercia alongside her husband, with none other than Charlemagne addressing them jointly in a letter. Archaeologists have now found the remains of the 8th-century Anglo-Saxon monastery where she lived out her later years as a royal abbess.
And in Spain, women may have been in leadership positions way back in the Bronze Age. Archaeologists have been excavating burials at a site called La Almoloya that dates to about 2200 to 1550 B.C. The different types of artifacts buried with men compared to those found with women’s remains suggest that while men had military control, it may have been the women, who came of age earlier and wore elaborate silver diadems, may have held political power in society.
Holy Cows: Cattle Cult and Prophesied Bison
In December 2019, Canada’s Wanuskewin Heritage Park began reintroducing bison, hunted nearly to extinction over a century ago. This fulfilled a long-held wish of the local Indigenous people, the Wahpeton Dakota, who prophesied the animals would bring good fortune. Eight months later, the park archaeologist realized the bison were taking their dust baths amid 1,000-year-old petroglyphs, including a 550-pound boulder carved to depict bison ribs—called a “ribstone”—as well as other carvings, and a stone knife that may have been used to carve them.
Cattle also made archaeological headlines in Saudi Arabia, where archaeologists dated the ancient monuments known as to 8,500 to 4,800 years ago. By comparison Stonehenge and the oldest Egyptian pyramids are 5,000 years old or less. We now know there are over 1,000 across 77,000 square miles of desert. They range from low rock walls forming long rectangles (and take their name from the Arabic word for the shapes) to more elaborate constructions with pillar, chambers, and interior walls.
And where the does cattle come in? The may have been built for religious rituals, praying for rainfall to support their cattle farming during droughts, as the region at the time would have been an unrecognizably verdant landscape.
Anything Found With a Metal Detector
It turns out that metal detecting is a pretty pandemic-safe hobby, so the world has seen an explosion of very discoveries made by backyard amateurs, like the man in Denmark who found a stunning cache of 6th century gold jewelry his first time using a metal detector. (At first, he was convinced he had dug up the lid of a herring can.)
The U.K. has proven particularly fertile ground, with one woman alone unearthing two separate hoards of Viking treasure on the Isle of Man. The nation’s other finds include a gold and enamel Medieval skull ring in Wales, the largest-ever haul of Anglo-Saxon gold coins, and a tiny gold book from the 15th century.
