Rare Discovery Of Roman Dodecahedron Fragment Adds To Archaeological Mystery

A chance find by an amateur metal detectorist has added to a long-running mystery of archaeology, as a fragment of an Ancient Roman dodecahedron has been found in the small town of Kortessem, in Belgium. 

The piece, originally part of a dodecahedron measuring 5-6 centimeters (2–2.36 inches) in size, shows signs of having been repaired in the past, with local archaeologists at the Flanders Heritage Agency suggesting that it may have been broken in some kind of ancient ritual.

Roman dodecahedra are something of a puzzle: more than 100 such artifacts have been found throughout Europe over the past few centuries, each of them meticulously cast in these perfect 12-sided polyhedra. Each face of the bronze dodecahedra has a small hole through the center, though no hole is the same size as another, and each vertex is decorated with a tiny bauble – though apart from that, the little doodads seem to have no distinctive markings at all.

We can infer that they must have been important, at least to some of their owners, since several have been found among coin hoards and – the new example notwithstanding – hardly any show signs of the kind of wear and tear you might expect over nearly two millennia of history. 

And yet the simple fact is that nobody knows what Roman dodecahedra were actually used for. In fact, if it wasn’t for the fact that hundreds of them have been discovered, you’d never know they existed at all, since no record of them has ever been found in contemporary art or writing.

That hasn’t stopped people from theorizing. Perhaps the mysterious little objects were used as rangefinders or angle measurers, people have suggested, or maybe the Romans used them for astronomical predictions to aid in agriculture. Since the advent of YouTube, the idea that the dodecahedra were used as knitting aids has proved particularly popular – but since even knitting needles aren’t known in the historical record until a good few centuries later, that hypothesis is likely not true. 

Instead, archaeologists at the Flanders Heritage Agency favor a more esoteric explanation. “There is increasing evidence that dodecahedrons may not have been practical objects, such as measuring instruments,” the statement says. “The known specimens are too different in dimensions and details for that.”

Man Stumbles On Vast Underground City Behind Wall During Home Reno—And Tunnels Go On Forever

Amid the strange fairy chimney stacks of eroded rock that litter the landscape of Cappadocia in central Turkey, little more than an inkling suggests that a sprawling subterranean city lies under the arid ground beneath one’s feet.

For centuries, the inhabitants of the Anatolian plateau have been carving dwellings, monasteries, and troglodyte villages out of the local soft volcanic rock, conjuring what look like scenes from a Tolkien novel today. There’s plenty enough to stir imaginations aboveground, luring tourists to hike and hot-air balloon in Cappadocia; meanwhile, an underground world with hundreds of miles of chambers and passages rests unseen below.

Called Elengubu in ancient times, after its recent rediscovery this cavernous city borrowed the namesake of its overlying district, Derinkuyu, in Nevşehir province. Abandoned centuries ago, the intricate tunnel network of Derinkuyu once offered safety and concealment for those seeking refuge amid persecution.

Yet the city was—and still is—intertwined with stone structures and dwellings overland. After it was abandoned, and after fading from public knowledge in the early 20th century, Derinkuyu’s accidental rediscovery in 1963 was credited to a home renovation. According to locals, a Turkish man who was expanding his domicile tore down a wall only to discover an abysmal passageway that seemed to go on forever, which led to the underground city’s prompt excavation. This was the first of some 600 entry points found connecting Derinkuyu with structures above.

Gargantuan in size, Derinkuyu spans some 275 square miles (445 square kilometers), descending 279 feet (85 meters) underground with some 18 levels. Once a bustling sub-terrestrial city, Derinkuyu is beset with living quarters for some 20,000 inhabitants, stables for livestock, wine and oil presses, cellars, chapels, schools, wells, and other amenities. This made the underground metropolis a fully self-sustaining community whose inhabitants could sever themselves from an outside world that was often fraught with danger in times of invasion or occupation.

Previously Unknown Group Of People In Prehistoric Siberia Found By DNA

Genetic analysis has unveiled a previously unknown group of people who lived in Siberia during the last Ice Age around the borders of modern-day Russia, China, Mongolia, and Kazakhstan. It appears this mysterious group of people also had links to the multiple waves of humans who made the daring journey to North America. 

By the looks of things, some people actually migrated back in the “opposite” direction from North America to North Asia via the Bering Sea. This ancient legacy of the Americas still lives on in some people currently living in northeastern Siberia.

To reach their findings, scientists led by the Max Planck Institute for Evolutionary Anthropology analyzed the genomes of ten individuals who lived in the Altai region of southern Siberia around 7,500 years ago. Paired with this, they looked at the genetic makeup of Eurasian and Native American populations in the present day. 

Their data revealed the Altai hunter-gatherers had a “unique gene pool” that indicates they were descendants of two key groups that lived in this part of Eurasia at the time: the paleo-Siberians and the Ancient North Eurasian (ANE) people. 

“We describe a previously unknown hunter-gatherer population in the Altai as early as 7,500 years old, which is a mixture between two distinct groups that lived in Siberia during the last Ice Age,” Cosimo Posth, senior study author from the University of Tübingen in Germany, said in a statement. 

“The Altai hunter-gatherer group contributed to many contemporaneous and subsequent populations across North Asia, showing how great the mobility of those foraging communities was,” he added.

Enigmatic ‘writing system’ in ice age cave art deciphered

Hunter-gatherers who painted on cave walls 20,000 years ago also left behind something quite unexpected.For years, archaeologists have worked to understand the hidden meanings in the thousands of examples of prehistoric art found on cave walls across Europe.

These artistic works often featured animals such as bison, fish, reindeer and (the now extinct) aurochs, but some of them also included a sequence of dots and marks that seemed to be some form of writing system – one which experts had long struggled to fully interpret.

Now, though, a new collaboration between researcher Ben Bacon and experts from Durham University and University College London has finally lifted the lid on exactly what these symbols meant.

It turns out that the marks were actually part of an ancient writing system – a lunar calendar which was used to document the timing of the reproductive cycles of the animals.This type of information would have been highly relevant to the hunter-gatherers of the time.

“The results show that ice age hunter-gatherers were the first to use a systemic calendar and marks to record information about major ecological events within that calendar,” said archaeologist Prof Paul Pettitt of Durham University.

Riddle solved: Why was Roman concrete so durable?

The ancient Romans were masters of engineering, constructing vast networks of roads, aqueducts, ports, and massive buildings, whose remains have survived for two millennia. Many of these structures were built with concrete: Rome’s famed Pantheon, which has the world’s largest unreinforced concrete dome and was dedicated in A.D. 128, is still intact, and some ancient Roman aqueducts still deliver water to Rome today. Meanwhile, many modern concrete structures have crumbled after a few decades.

Researchers have spent decades trying to figure out the secret of this ultradurable ancient construction material, particularly in structures that endured especially harsh conditions, such as docks, sewers, and seawalls, or those constructed in seismically active locations.

Now, a team of investigators from MIT, Harvard University, and laboratories in Italy and Switzerland, has made progress in this field, discovering ancient concrete-manufacturing strategies that incorporated several key self-healing functionalities. The findings are published today in the journal Science Advances, in a paper by MIT professor of civil and environmental engineering Admir Masic, former doctoral student Linda Seymour ’14, PhD ’21, and four others.

For many years, researchers have assumed that the key to the ancient concrete’s durability was based on one ingredient: pozzolanic material such as volcanic ash from the area of Pozzuoli, on the Bay of Naples. This specific kind of ash was even shipped all across the vast Roman empire to be used in construction, and was described as a key ingredient for concrete in accounts by architects and historians at the time.

OLDEST KNOWN PROJECTILE POINTS UNCOVERED IN THE AMERICAS

ARCHAEOLOGISTS FROM THE OREGON STATE UNIVERSITY HAVE UNCOVERED A COLLECTION OF PROJECTILE POINTS THAT DATE FROM ROUGHLY 15,700 YEARS AGO.

The researchers found 13 full and numerous fragmentary projectile points at the Cooper’s Ferry site along the Salmon River in present-day Idaho. They are 2,300 years older than the points previously found at the same site, and 3,000 years older than the Clovis fluted points found throughout North America.

The Salmon River site is on traditional Nez Perce land, known to the tribe as the ancient village of Nipéhe. The land is currently held in public ownership by the federal Bureau of Land Management.

The points are revelatory not just in their age, but in their similarity to projectile points found in Hokkaido, Japan, dating to 16,000-20,000 years ago. Their presence in Idaho adds more detail to the hypothesis that there are early genetic and cultural connections between the ice age peoples of Northeast Asia and North America.

Loren Davis, an anthropology professor at OSU said: “The earliest peoples of North America possessed cultural knowledge that they used to survive and thrive over time. Some of this knowledge can be seen in the way people made stone tools, such as the projectile points found at the Cooper’s Ferry site.”

“By comparing these points with other sites of the same age and older, we can infer the spatial extents of social networks where this technological knowledge was shared between peoples,” added Davis.

6 Ancient Sites Aligned With the Solstice and Equinox

Across time, people have marked the changing of seasons—sometimes in dramatic ways! In honor of the solstice on December 21, let’s look at six amazing and ancient sites aligned with the solstices and equinoxes.

Did you know that the equinoxes and solstices happen at the same moment around the world? Even though we all have different time zones, these are astronomical events based on our planet’s orbit around the Sun and tilt on its axis.

Our ancestors lived amidst nature more than most of us do today. They observed the universe, marveling in its rhythms. They used the Sun and the Moon as a sort of calendar, tracking the Sun’s path across the sky. Here are some examples of the ancient sites and monuments that were built to align with the solstices or equinoxes.

Our ancestors built the first observatories to track the sun’s progress.

OLDEST COOKED FOOD EVER FOUND UPENDS THE “PALEO” THEORY OF ANCIENT HUMAN DIETS

WE HUMANS CAN’T stop playing with our food. Just think of all the different ways of serving potatoes — entire books have been written about potato recipes alone. The restaurant industry was born from our love of flavoring food in new and interesting ways.

My team’s analysis of the oldest charred food remains ever found shows that jazzing up your dinner is a human habit dating back at least 70,000 years.

Imagine ancient people sharing a meal. You would be forgiven for picturing people tearing into raw ingredients or maybe roasting meat over a fire, as that is the stereotype. But our new study showed both Neanderthals and Homo sapiens had complex diets involving several steps of preparation and took an effort to season and use plants with bitter and sharp flavors.

This degree of culinary complexity has never been documented before for Palaeolithic hunter-gatherers.

Before our study, the earliest known plant food remains in southwest Asia were from a hunter-gatherer site in Jordan, roughly dating to 14,400 years ago, reported in 2018.

We examined food remains from two late Paleolithic sites, which cover a span of nearly 60,000 years, to look at the diets of early hunter-gatherers. Our evidence is based on fragments of prepared plant foods (think burnt pieces of bread, patties, and porridge lumps) found in two caves. To the naked eye or under a low-power microscope, they look like carbonized crumbs or chunks with fragments of fused seeds. But a powerful scanning electron microscope allowed us to see details of plant cells.

168 NAZCA GEOGLYPHS IDENTIFIED IN PERU

YAMAGATA UNIVERSITY, WORKING IN PARTNERSHIP WITH PERUVIAN ARCHAEOLOGISTS, HAVE IDENTIFIED 168 NAZCA GEOGLYPHS IN THE NASCA PAMPA AND SURROUNDING AREA.

The researchers conducted field surveys using high-resolution aerial photography and drone images, leading to the discovery of 168 geoglyphs that date from between 100 BC and AD 300.

This adds to 190 geoglyphs previously discovered between 2004 and 2018, that led to the creation of an archaeological park in the Aja area in 2017 by the Peruvian Ministry of Culture.

The new geoglyphs depict images of humans, camelids, birds, orcas, felines, and snakes, which were created by removing black stones from the surface of the earth to expose a white sandy surface beneath.

Current research suggests that there are two types of geoglyphs: a linear type and a relief type. Of the geoglyphs discovered in the study, only five are linear, while 163 are relief type, measuring less than 10 metres in diameter and mainly distributed along ancient trails.

Scientists Are Investigating Signs of Ancient Human Civilization Underwater

Archaeologists are trying to piece together the mystery of an underwater trail of ancient rock piles, or cairns, that stretch for miles under the shimmering waters of Lake Constance, a glacial lake that lies between Germany, Austria, and Switzerland, and which appear to have been made by humans who lived some 5,500 years ago, according to a 2021 study.

The huge cairns have attracted public attention and expert debate ever since they were first discovered in 2015 by the Institute for Lake Research in Langenargen. Roughly 170 of these rock formations are arranged in a line under the shallow waters of Lake Constance, several hundred feet from its southwest Swiss shore. 

A team led by Urs Leuzinger, an archaeologist at the Museum of Archaeology of the Canton of Thurgau, have amassed compelling evidence that the rock formations were made by humans who lived in the area during the Neolithic period. 

The piles are several dozen feet wide, with heights of up to six feet, distinguishing them as impressive structures that would have required a lot of effort and time to build, though “the function of this 10-kilometer long prehistoric feature remains enigmatic,” according to a 2021 study published in the Annual Review of Swiss Archaeology. The findings of this study will be presented in a pop-up exhibit this week called “Bodensee Stonehenge” (meaning Lake Constance Stonehenge) at the Office for Archaeology Thurgau.
