Oldest Submerged City Found to be Even Older

Ruins of Pavlopetri on the seabed.

The world’s oldest submerged town ~ Pavlopetri, off the southern Laconia coast of Greece ~ contains ceramics dating back to the Final Neolithic period. Archaeologists now believe the town was occupied 5,000 years ago, some 1,200 years earlier than originally thought.

As a Mycenaean town, the Pavlopetri site offers potential new insights into the workings of Mycenaean society. Pavlopetri has added importance as it was a maritime settlement from which its inhabitants coordinated local and long distance trade.

Dr Jon Henderson, an underwater archaeologist from the University of Nottingham, tells ScienceDaily: “This site is unique in that we have almost the complete town plan, the main streets and domestic buildings, courtyards, rock-cut tombs and what appear to be religious buildings, clearly visible on the seabed. Equally as a harbor settlement, the study of the archaeological material we have recovered will be extremely important in terms of revealing how maritime trade was conducted and managed in the Bronze Age.”

This summer an organized team of archaeologists conducted a detailed digital underwater survey and study of the structural remains, which until this year were thought to belong to the Mycenaean period ~ around 1600 to 1000 BC. Their investigations revealed another 150 square meters of new buildings as well as ceramics that suggest the site was occupied throughout the Bronze Age ~ from at least 2800 BC to 1100 BC.

Likely Site of Fabled Labyrinth is Found

Ancient vase depiction of Theseus slaying the Minotaur.

A team of Greek and English scholars believe they have discovered a likely location for the site of the ancient Labyrinth, the legendary maze where the mythical Minotaur supposedly roamed. The elaborate network of underground tunnels is in an old stone quarry near the town of Gortyn, formerly the Roman capital of Crete.

For the last century, the town of Knossos ~ about 20 miles from Gortyn ~ has been touted as the location of the Labyrinth. According to London’s The Indepdendent:

Nicholas Howarth, an Oxford University geographer who led the expedition (to Gortyn), said there was a danger of Gortyn being lost from the story of the Labyrinth because of the overpowering position that Knossos had taken in the legend, a position fostered by Arthur Evans, a wealthy English archaeologist who excavated the site between 1900 and 1935.

"People come not just to see the controversial ruins excavated and reconstructed by Evans, but also to seek a connection to the mythical past of the Age of Heroes. It is a shame that almost all visitors to Knossos have never heard of these other possible 'sites' for the mythical Labyrinth," Mr Howarth said.

Visitors to Knossos are told the site was almost certainly the home of the legendary King Minos, who was said to have constructed the Labyrinth for the Minotaur, a monster resulting from the mating of the king’s wife with a bull.

But the caves at Gortyn ~ known locally as the Labyrinthos Caves ~ are nearly three miles of interlocking tunnels with widened chambers and dead-end rooms, closer to the ancient descriptions of the Labyrinth.

"Going into the Labyrinthos Caves at Gortyn, it's easy to feel that this is a dark and dangerous place where it is easy to get lost,” Howarth says. “Evans' hypothesis that the palace of Knossos is also the Labyrinth must be treated skeptically."

'Atlantis' Eruption Provoked Massive Tsunami

Artist's conception of Atlantis ruins.

The volcanic explosion that might have obliterated the legendary isle of Atlantis also triggered a tsunami that traveled hundreds of miles along the Mediterranean coast, scientists now suggest.

The islands that make up the small circular archipelago of Santorini ~ 120 miles southeast of Greece ~ are what remain of what once was a single island, before one of the largest volcanic eruptions in human antiquity occurred between 1630 BC and 1550 BC.

Speculation has abounded as to whether the Santorini eruption may have inspired the legend of Atlantis. The explosion might have given rise to the story of a lost empire by destroying the real-life Minoan civilization that once dominated the Mediterranean.

Now, researchers diving as far as 65 feet deep off the coast of Israel have collected tubes of sediment, or cores, from the seabed. Within the cores, they found evidence of up to nearly 16 inches of sediment deposited roughly about the date of the Santorini eruption.

According to LiveScience:

The dramatic changes in life triggered by the tsunami "might have been part of the fabric of the Atlantis story," said researcher Beverly Goodman, a marine geoarchaeologist at Interuniversity Institute for Marine Sciences at Eilat, Israel.

Although Atlantis itself "is a myth and legend, it is informative about the experiences of the ancients," Goodman said.
"It may very well be the case that those passing the story on had heard of or witnessed events in which coastal buildings went underwater because of earthquakes; beachfront towns were flooded during tsunamis; islands were created by underwater volcanic activity. There may be that grain of truth that lent legitimacy and a certain reality to the legend of Atlantis."

To better reconstruct the Santorini tsunami, the scientists are planning to analyze deposits closer to the eruption, such as on Crete and in western parts of Turkey.

Familiar Situations Provoked Athens' Downfall

Artist's conception of Athens in its glory.

Ancient Athens imploded during the 4th century BC amid a crippling economic downtown as its army fought unpopular wars on foreign soil and immigrants surged across its borders.

Cambridge University professor Michael Scott in his new study entitled From Democrats to Kings, contends that the collapse of Greek democracy and of Athens in particular offer a stark warning from history which is often overlooked.

"In many ways this was a period of total uncertainty just like our own time," Scott told PhysOrg.com. "There are grounds to consider whether we want to go down the same route that Athens did.”

According to PhysOrg.com:

It was not the loss of its empire and defeat in war against Sparta at the end of the 5th century that heralded the death knell of Athenian democracy ~ as it is traditionally perceived. Athens' democracy in fact recovered from these injuries within years. Instead, Dr. Scott argues that the strains and stresses of the 4th century BC, which our own times seem to echo, proved too much for the Athenian democratic system and ultimately caused it to destroy itself.

"If history can provide a map of where we have been, a mirror to where we are right now and perhaps even a guide to what we should do next, the story of this period is perfectly suited to do that in our times," Dr. Scott said.

"It shows how an earlier generation of people responded to similar challenges and which strategies succeeded. It is a period of history that we would do well to think about a little more right now ~ and we ignore it at our peril."

The name of "democracy," for example, became an excuse to turn on anyone regarded as an enemy of the state. Scott's study also marks an attempt to recognize figures such as Isocrates and Phocion ~ sage political advisers who tried unsuccessfully to steer Athens away from crippling confrontations with other Greek states and Macedonia.

Deforestation May Have Destroyed Mayan Culture

Mayan mural depicting the god of maize.

Using computer-based simulations and space-based imaging, a NASA-funded project is providing strong evidence that the once-vibrant Mayan culture destroyed itself through extreme deforestation.

"They did it to themselves," says veteran archeologist Tom Sever. According to NASA sources:

A major drought occurred about the time the Maya began to disappear. And at the time of their collapse, the Maya had cut down most of the trees across large swaths of the land to clear fields for growing corn to feed their burgeoning population. They also cut trees for firewood and for making building materials.

"They had to burn 20 trees to heat the limestone for making just 1 square meter of the lime plaster they used to build their tremendous temples, reservoirs, and monuments," explains Sever.

. . . "By interpreting infrared satellite data, we've located hundreds of old and abandoned cities not previously known to exist. The Maya used lime plaster as foundations to build their great cities filled with ornate temples, observatories, and pyramids. Over hundreds of years, the lime seeped into the soil. As a result, the vegetation around the ruins looks distinctive in infrared to this day."

Drought also made it more difficult for the Maya to store enough water to survive the dry season. "The cities tried to keep an 18-month supply of water in their reservoirs," says Sever. "For example, in Tikal there was a system of reservoirs that held millions of gallons of water. Without sufficient rain, the reservoirs ran dry."

For 1200 years, the Maya dominated Central America. At their peak around 900 AD, Maya cities teemed with more than 2,000 people per square mile ~ comparable to modern Los Angeles County. Even in rural areas, the Maya numbered 200 to 400 people per square mile.

Scientists Accurately Reproduce Shroud's Image

One of Christendom’s most revered relics ~ the linen shroud that allegedly covered Jesus after his crucifixion ~ was dealt a blow Monday when scientists announced they could reproduce the mysterious image of a wounded man, using techniques available in the 14th century.

The Shroud of Turin is believed by man to bear the figure of a crucified man, with blood seeping out of his wounds in his hands and feet. The shroud’s believers contend the image was impressed into the linen fibers supernaturally at the time of Christ’s resurrection.

The Italian Committee for Checking Claims on the Paranormal said Monday that new evidence points to the shroud as being a medieval forgery. According to the Associated Press:

In 1988, scientists used radiocarbon dating to determine it was made in the 13th or 14th century. But the dispute continued because experts couldn't explain how the faint brown discoloration was produced, imprinting on the cloth a negative image centuries before the invention of photography.

Many still believe that the shroud "has unexplainable characteristics that cannot be reproduced by human means," lead scientist Luigi Garlaschelli said in the statement. "The result obtained clearly indicates that this could be done with the use of inexpensive materials and with a quite simple procedure."

Garlaschelli said in an interview with La Repubblica daily that his team used a linen woven with the same technique as the shroud and artificially aged by heating it in an oven and washing it with water. The cloth was then placed on a student, who wore a mask to reproduce the face, and rubbed with red ochre, a well known pigment at the time.

The shroud is first recorded in history around 1360 in the hands of a French knight ~ a late appearance that is one of the reasons why some scientists are skeptical of its authenticity.

"Bluehenge" Circle Found Near Stonehenge

Some spotted dolerite monoliths possibly erected first at Bluehenge.

In what is being termed one of the most important prehistoric finds in decades, archaeologists this summer secretly unearthed another prehistoric circle, this one just a mile from Stonehenge.

Researchers are calling it "Bluehenge" after the color of the 27 giant Welsh stones it once incorporated, but which are now missing. According to the London Daily Mail:

Bluehenge was put up 5,000 years ago ~ around the same time as work began on Stonehenge ~ and appears to have been a miniature version of it. The two circles stood together for hundreds of years before Bluehenge was dismantled. Researchers believe its stones were used to enlarge Stonehenge during one of a number of redevelopments.

Professor Tim Darvill, Stonehenge expert at Bournemouth University, said: “This adds to the richness of the story of Stonehenge. We thought we knew it all, but over the last few years we have discovered that something as familiar as Stonehenge is still a challenge to explore and understand. It wouldn't surprise me if there weren't more circles.”

All that remains of the 60-foot-wide Bluehenge are the holes of 27 giant stones set on a ramped mount. Chips of blue stone found in the holes appear to be identical to the blue stones used in Stonehenge.
The four-ton monsters, made of Preseli Spotted Dolerite ~ a chemically altered igneous rock harder than granite ~ were mined in the Preseli Mountains in Pembrokeshire and then rolled, dragged and floated the 200 miles to the site on the banks of the Avon in Wiltshire.

Stonehenge is believed to have been built and rebuilt over 600 years in three main phases, the earliest around 300 BC.

Hawaiians Possibly Early New Zealanders

Rendition of ancient New Zealand war canoe.

Researchers are saying Polynesian canoe design suggests New Zealand was at least partially settled from Hawaii.

New data suggests a course of Polynesian settlement that started in the far western islands and jumped to the far eastern islands before then working backwards towards the original point of origin. According to the New Zealand Herald:

Archaeologists have said the Lapita peoples ~ probably from China and Southeast Asia ~ who colonized Pacific islands between about 1400 BC and 900 BC became the Polynesians who settled several island groups outwards out of Tonga and Samoa beginning about 500 BC, arriving in the Marquesas about 300 AD, the Hawaiian islands by 800 AD to 900 AD, and finally in New Zealand about 1200.

Stanford University researchers Marcus Feldman and Paul Ehrlich and biologist Deborah Rogers analyzed a 1930s study of traditional canoe design by A.C Haddon and James Hornell.

"This is not a paper about canoes," Ehrlich said. "It's a paper about whether or not there are discernable, explicable patterns in history."

They tracked functional characteristics such as outrigger attachments, construction technique, keel shape as well as painting, designs and figureheads of pre-European canoes from different island groups.

Canoe construction techniques persisted. The Polynesians brought traditional techniques, but changed decorative features as they colonized new island groups.

Digital Images Recreate Aztec's Templo Mayor

Digital visualization of Templo Mayor prior to destruction.

Templo Mayor plaza viewed from the Temple of the Sun.

Digital images now provide what is considered a reasonable concept of the appearance of a spectacular 16th century Aztec temple in what is today Mexico City.

Antonio Serrato-Combe, professor of architecture at the University of Utah, devoted two decades to digitally recreating ancient structures of the Aztecs. His major accomplishment is the construction of the Templo Mayor Precinct in Tenochtitlan, in what is modern day Mexico City. Destroyed by Hernando Cortes in 1521, the Templo Mayor was the center of Aztec ceremonial life and served as the setting for highly energized rituals.

According to PhysOrg.com:

The question of what the Aztec Templo Mayor Precinct looked like has piqued the curiosity of many, including Serrato-Combe. For more than two decades, he has been trying to solve the mystery on how the capital of the Aztecs looked by using the technology and tools of architecture.

"The Aztec capital was a thriving metropolis planned and built according to principles that not only understood and applied critical environmental issues, but added holistic concepts as well," explains Serrato-Combe. "The Aztecs did not compartmentalize the arts. The final result was a unique combination of architecture, sculpture, painting, costume, wall and sand painting, pottery, masks, amulets, all into one expression. I envy those individuals who had the opportunity to experience those environments."

Combe's research and visualizations are centered on historic and archaeological studies conducted on-site in Mexico City, in conjunction with additional extensive research, very time consuming, due to the complexity and diverse nature of the historic and archeological record.

Mayan Temples Play 'Raindrop' Music

El Castillo possibly a temple to the Mayan rain god Chaac.

Researchers are speculating that the Mayans constructed some of Mexico’s ancient pyramids to reverberate with peculiar “raindrop music” ~ the sound of raindrops falling into a bucket of water ~ as people climbed them.

For years archaeologists have been familiar with the raindrop sounds made by footsteps on El Castillo, a hollow pyramid on the Yucatán Peninsula. But why the steps should sound like this and whether the effect was intentional remained unclear.

According to New Scientist magazine:

To investigate further, Jorge Cruz of the Professional School of Mechanical and Electrical Engineering in Mexico City and Nico Declercq of the Georgia Institute of Technology compared the frequency of sounds made by people walking up El Castillo with those made at the solid, uneven-stepped Moon Pyramid at Teotihuacan in central Mexico.

At each pyramid, they measured the sounds they heard near the base of the pyramid when a student was climbing higher up. Remarkably similar raindrop noises, of similar frequency, were recorded at both pyramids, suggesting that rather than being caused by El Castillo being hollow, the noise is probably caused by sound waves traveling through the steps hitting a corrugated surface, and being diffracted, causing the particular raindrop sound waves to propagate down along the stairs.

El Castillo is widely believed to have been devoted to the feathered serpent god Kukulcan, but Cruz thinks it may also have been a temple to the rain god Chaac. Indeed, a mask of Chaac is found at the top of El Castillo and also in the Moon Pyramid.

"The Mexican pyramids, with some imagination, can be considered musical instruments dating back to the Mayan civilization," says Cruz, although he adds that there is no direct evidence that the Mayans actually played them.

Anglo-Saxon Treasure is a Mystery

Sample of the huge stash of Anglo-Saxon precious-metal objects.

Terry Herbert’s spectacular find with a metal detector of the largest known stash of 7th century Anglo-Saxon gold and silver has rocked the world of archaeology, and more details are being released with each passing day. The find was disclosed last week.

Herbert had been wielding his metal detector for 18 years and in July was searching land in South Staffordshire belonging to a farmer friend.

"I have this phrase that I say sometimes: 'Spirits of yesteryear take me where the coins appear,’ but on that day I changed ‘coins’ to ‘gold,’" he recalls. "I don't know why I said it that day, but I think somebody was listening and directed me to it.”

He found an estimated 1,500 gold and silver pieces, making it the largest discovery of Anglo-Saxon gold yet recovered.

What Is It?

“For the Anglo-Saxon period, this is an awful lot of wealth for one person, or even one people, to have left in one place,” says Dr. Michael Lewis of the British Museum. “At the moment, we can say what it isn't, even if we can't say what it is. It's not associated with a burial, like Sutton Hoo was, for example.

“After that, there are two main possibilities,” he continues. “The first is that this treasure has been purposefully deposited, like an offering to a god. But, from my 21st-Century perspective, I find it bewildering that someone could shove so much metalwork into the ground as an offering. That seems like overkill.

“The other possibility is it's a treasure chest that got lost, or they couldn't come back for it,” Lewis says.

Genetics Dispel Ancient Indian Division


The longstanding belief of an ancient division between India’s Aryan and Dravidian populations ~ essentially a north-south separation ~ has been disproved by genetic researchers from Harvard and India.

"This paper rewrites history. There is no north-south divide,'' Lalji Singh, former director of the Centre for Cellular and Molecular Biology (CCMB) and a co-author of the study, said at a press conference in Hyderabad on Thursday.

According to the Times of India:

Senior CCMB scientist Kumarasamy Thangarajan said there was no truth to the Aryan-Dravidian theory as they came hundreds or thousands of years after the ancestral north and south Indians had settled in India.

The study analysed 500,000 genetic markers across the genomes of 132 individuals from 25 diverse groups from 13 states. All the individuals were from six-language families and traditionally "upper'' and "lower'' castes and tribal groups. "The genetics proves that castes grew directly out of tribe-like organizations during the formation of the Indian society,'' the study said. Thangarajan noted that it was impossible to distinguish between castes and tribes since their genetics proved they were not systematically different.

“. . .The initial settlement took place 65,000 years ago in the Andamans and in ancient south India around the same time, which led to population growth in this part,'' said Thangarajan. "At a later stage, 40,000 years ago, the ancient north Indians emerged which in turn led to rise in numbers here. But at some point of time, the ancient north and the ancient south mixed, giving birth to a different set of population. And that is the population which exists now and there is a genetic relationship between the population within India.''

The study reveals that the present-day Indian population is a mix of ancient north and south, bearing the genomic contributions from two distinct ancestral populations ~ the Ancestral North Indian (ANI) and the Ancestral South Indian (ASI).
