Ohio: Hopewell Civilzation's Pipes From Illinois?

In the early 1900s, an archaeologist, William Mills, dug up a treasure-trove of carved stone pipes that had been buried almost 2,000 years earlier. Mills was the first to dig the Native American site, called Tremper Mound, in southern Ohio. And when he inspected the pipes, he made a reasonable – but untested – assumption. The pipes looked as if they had been carved from local stone, and so he said they were. That assumption, first published in 1916, has been repeated in scientific publications to this day. But according to a new analysis, Mills was wrong.

In a new study, the first to actually test the stone pipes and pipestone from quarries across the upper Midwest, researchers conclude that those who buried the pipes in Tremper Mound got most of their pipestone – and perhaps even the finished, carved pipes – from Illinois.

The researchers spent nearly a decade on the new research. They first collected the mineralogical signatures of stone found in traditional pipestone quarries in Illinois, Kansas, Michigan, Minnesota, Missouri and Ohio. Then they compared the material found in those quarries to the mineralogical makeup of the artifacts left behind by the people of Tremper Mound.

Less than 20 percent of the 111 Tremper Mound pipes they tested were made from local Ohio stone. About 65 percent were carved from flint clay found only in northern Illinois and 18 percent were made of a stone called catlinite – from Minnesota.

The researchers are still puzzling over how most of these materials made it to Ohio from Illinois, and are baffled by another new discovery. Pipes from a site only about 40 miles north of Tremper Mound, an elaborate cluster of immense mounds known as Mound City, were carved almost entirely from local stone. Mound City was inhabited at about the same time or shortly after Tremper Mound, and the pipes found there are stylistically very similar to the Tremper pipes. (See a slideshow of some pipes.)

The researchers describe their findings in a paper in American Antiquity.

These results should remind archaeologists that things are not as simple as they sometimes appear, said Thomas Emerson, the principal investigator on the study and the director of the Illinois State Archaeological Survey (ISAS) at the University of Illinois.

“This is how mythology becomes encased in science,” he said.

The study also confirms that the people who produced these pipestone artifacts, known today as members of the Hopewell tradition, were more diverse and varied in their cultural practices than scientists once appreciated, Emerson said.

The Hopewell people, who lived in the region from about 100 B.C. to roughly A.D. 400, have long been the subject of speculation, as the artifacts they left behind and the manner in which these goods were disposed of are not easily understood. Those living in southeastern Ohio, especially, seemed to be “conspicuous consumers and connoisseurs of the exotic,” Emerson said.

The Hopewell people from that area collected “massive assemblages of obsidian from Wyoming, mica from the Appalachians, and caches of elaborately carved pipes,” Emerson said. They also collected shells from the Gulf Coast, along with the skulls of exotic animals (an alligator, for instance).

“Strange animals, strange minerals, strange things were really a focus,” he said.

Most of the carved stone pipes from that era have been found in Ohio, where very large caches often containing more than 100 pipes were ritually broken, burned and buried, Emerson said. The same style of pipes are found in Illinois, but many fewer have been uncovered in Illinois to date, he said, and they are dispersed, not heaped together in giant hordes as in Ohio. (Watch a video about the Hopewell pipes.

There is evidence of stone carving at the Illinois sources where the stone was gathered, but none at Tremper Mound, suggesting that the Illinois stone was carved into pipes before it was transported to Ohio.

The team used a variety of techniques to analyze the material in the quarries and the artifacts. One method, called X-ray diffraction (XRD), produces a distinct signal that reflects the proportion of minerals in different types of stone. The stone must be pulverized, however, to subject it to XRD. To analyze the intact pipes, the researchers used a non-destructive portable technology, called PIMA, which illuminates a specimen with short-wavelength infrared radiation and records the refracted (unabsorbed) wavelengths, allowing investigators to identify the minerals present. They verified the accuracy of the PIMA by comparing its results to those obtained with XRD on quarry specimens and broken pipes.

The new findings should challenge archaeologists to look more carefully at the evidence left behind by the Hopewell people, Emerson said.

“This study really says to the archaeological community, you need to go back to the drawing board,” he said. “You’ve been telling stories for decades that are based on essentially misinformation.”




Farm from the period of the Hasmonean dynasty founded by the Maccabees

...Archaeologists have announced their discovery of an agricultural farm in Jerusalem's Kiryat Hayovel neighborhood that dates from the period of the Hasmonean dynasty founded by the Maccabees.

The farm was discovered on Hantke Street, during construction work for a light rail line in the area.

The findings indicate two distinct stages of use, one from the Hellenistic period, between 400 B.C.E. and 200 B.C.E., and one from the Roman period, between the middle of the second century B.C.E. and the middle of the first century B.C.E., which corresponds to the time of Hasmonean rule.

There are indications that with more excavation, the farm could turn out to be part of a town, said Israel Antiquities Authority archaeologist Daniel Ein Mor, who is leading the Hantke Street dig.

"We discovered rock foundations in the buildings, pointing to a huge investment," he said. "The quality of the construction is excellent, so I wouldn't be surprised if future findings reveal it is even something bigger, maybe a settlement."

So far archaeologists have uncovered a wine press, outdoor stoves, canals and a large amount of earthenware, including a small perfume bottle, in the area. They also found a small lead weight with a carved letter, possibly the Hebrew letter "yod," which in this case was written upside down.

Ein Mor said he thinks the inhabitants cultivated the land near the Ein Karem Stream, where ancient terraced fields have been discovered...

Chemical analysis reveals first cheese making in Northern Europe in the 6th millennium BC



The first unequivocal evidence that humans in prehistoric Northern Europe made cheese more than 7,000 years ago is described in research by an international team of scientists, led by the University of Bristol, UK, published today in Nature.

By analysing fatty acids extracted from unglazed pottery pierced with small holes excavated from archaeological sites in Poland, the researchers showed that dairy products were processed in these ceramic vessels. Furthermore, the typology of the sieves, close in shape to modern cheese-strainers, provides compelling evidence that these specialised vessels have been used for cheese-making.

Before this study, milk residues had been detected in early sites in Northwestern Anatolia (8,000 years ago) and in Libya (nearly 7,000 years ago). Nevertheless, it had been impossible to detect if the milk was processed to cheese products.

Researchers from the Organic Geochemistry Unit at the University of Bristol, together with colleagues at Princeton (USA), Łódź, Gdánsk and Poznań (Poland) studied unglazed pottery from the region of Kuyavia (Poland) dating from around 7,000 years ago. These had been typologically interpreted as cheese-strainers by archaeologists for more than 30 years due to the peculiar presence of small sized holes on the surface of the sherds. In fact, these archaeological sherds looked like modern cheese-strainers.

Using lipid biomarker and stable isotope analysis, researchers examined preserved fatty acids trapped in the fabric of the pottery and showed that the sieves had indeed been used for processing dairy products. Milk residues were also detected in non-perforated bowls, which may have been used with the sieves.

Contrastingly, the analyses of non-perforated pottery (cooking pots or bottles) demonstrated that they were not used for processing milk. The presence of ruminant carcass fats in cooking pots showed that they were likely used to cook meat, while the presence of beeswax in bottles suggests the sealing of the pottery to store water.

Thus, the analyses of such a range of ceramics from the same area showed for the first time that different types of pottery were used in a specific manner, with sieves (and maybe bowls) being used for cheese-making, cooking pots for cooking meat and waterproofed bottles for storing water.

The processing of milk and particularly the production of cheese were critical in early agricultural societies as it allowed the preservation of milk in a non-perishable and transportable form and, of primary importance, it made milk a more digestible commodity for early prehistoric farmers.

Mélanie Salque, a PhD student from the University of Bristol and one of the authors of the paper said: "Before this study, it was not clear that cattle were used for their milk in Northern Europe around 7,000 years ago. However, the presence of the sieves in the ceramic assemblage of the sites was thought to be a proof that milk and even cheese was produced at these sites. Of course, these sieves could have been used for straining all sorts of things, such as curds from whey, meat from stock or honeycombs from honey. We decided to test the cheese-making hypothesis by analysing the lipids trapped into the ceramic fabric of the sieves.

"The presence of milk residues in sieves (which look like modern cheese-strainers) constitutes the earliest direct evidence for cheese-making. So far, early evidence for cheese-making were mostly iconographic, that is to say murals showing milk processing, which dates to several millennia later than the cheese strainers."

Peter Bogucki one of the co-authors of this new study and proponent of the cheese strainer hypothesis nearly 30 years ago notes that: "As well as showing that humans were making cheese 7,000 years ago, these results provide evidence of the consumption of low-lactose content milk products in Prehistory. Making cheese allowed them to reduce the lactose content of milk, and we know that at that time, most of the humans were not tolerant to lactose. Making cheese is a particularly efficient way to exploit the nutritional benefits of milk, without becoming ill because of the lactose."

Extensive New First Temple Period Remains Unearthed in Jerusalem


Findings include what could be the largest haul yet of pottery fragments from the time of Jerusalem's First Temple.


Archaeologists, students and volunteers have unearthed archaeological remains that will shed additional light on the occupation of ancient Jerusalem's royal precinct of the time of the Israelite and Judahite kings, going back to the 10th century BCE.
Under the direction of Eilat Mazar of the Hebrew University in Jerusalem, painstaking excavation by a team of archaeologists, including a group from the Herbert W. Armstrong College in the U.S., has revealed extensive architectural elements, including floor layers and walls, that suggest at least one very large structure of yet-to-be-determined function. This, after weeks of excavating through layers containing artifacts, architectural elements and other features representing later periods of occupation, including those of the Byzantine and Second Temple (Herodian) periods.



"Now", says Mazar, "all over the place we have Iron Age (1300 - 600 BCE ) floor layers, we have alot of Iron Age pottery, 10th century BCE pottery......I think it's the richest assemblage we have ever had from the 10th century until now in Jerusalem."
Like the other structures within the vicinity, a building of possible monumental proportions may be emerging. As she stood above looking down at the excavation area spread out below her, she speaks to a small group of observers standing next to her, sharing her vantage point. "We have these large walls that show that this was a very large structure -- it's huge..."

European Romani exodus began 1,500 years ago, DNA evidence shows



Despite their modern-day diversity of language, lifestyle, and religion, Europe's widespread Romani population shares a common, if complex, past. It all began in northwestern India about 1,500 years ago, according to a study reported on December 6th in Current Biology, a Cell Press publication, that offers the first genome-wide perspective on Romani origins and demographic history.

The Romani represent the largest minority group in Europe, consisting of approximately 11 million people. That means the size of the Romani population rivals that of several European countries, including Greece, Portugal, and Belgium.

"We were interested in exploring the population history of European Romani because they constitute an important fraction of the European population, but their marginalized situation in many countries also seems to have affected their visibility in scientific studies," said David Comas of the Institut de Biologia Evolutiva at Universitat Pompeu Fabra in Spain.

The Romani people lack written historical records on their origins and dispersal. To fill in the gaps in the new study, Comas and Manfred Kayser from Erasmus University Rotterdam in the Netherlands, together with their international European colleagues, gathered genome-wide data from 13 Romani groups collected across Europe to confirm an Indian origin for European Romani, consistent with earlier linguistic studies.

The genome-wide evidence specified the geographic origin toward the north or northwestern parts of India and provided a date of origin of about 1,500 years ago. While the Middle East and Caucasus regions are known to have had an important influence on Romani language, the researchers saw limited evidence for shared genetic ancestry between the European Romani and those who live in those regions of the world today. Once in Europe, Romani people began settling in various locations, likely spreading across Europe via the Balkan region about 900 years ago.

"From a genome-wide perspective, Romani people share a common and unique history that consists of two elements: the roots in northwestern India and the admixture with non-Romani Europeans accumulating with different magnitudes during the out-of-India migration across Europe," Kayser said. "Our study clearly illustrates that understanding the Romani's genetic legacy is necessary to complete the genetic characterization of Europeans as a whole, with implications for various fields, from human evolution to the health sciences."

Native Americans and Northern Europeans more closely related than previously thought



Using genetic analyses, scientists have discovered that Northern European populations—including British, Scandinavians, French, and some Eastern Europeans—descend from a mixture of two very different ancestral populations, and one of these populations is related to Native Americans. This discovery helps fill gaps in scientific understanding of both Native American and Northern European ancestry, while providing an explanation for some genetic similarities among what would otherwise seem to be very divergent groups. This research was published in the November 2012 issue of the Genetics Society of America's journal GENETICS (http://www.genetics.org).

According to Nick Patterson, first author of the report, "There is a genetic link between the paleolithic population of Europe and modern Native Americans. The evidence is that the population that crossed the Bering Strait from Siberia into the Americas more than 15,000 years ago was likely related to the ancient population of Europe."

To make this discovery, Patterson worked with Harvard Medical School Professor of Genetics David Reich and other colleagues to study DNA diversity, and found that one of these ancestral populations was the first farming population of Europe, whose DNA lives on today in relatively unmixed form in Sardinians and the people of the Basque Country, and in at least the Druze population in the Middle East. The other ancestral population is likely to have been the initial hunter-gathering population of Europe. These two populations were very different when they met. Today the hunter-gathering ancestral population of Europe appears to have its closest affinity to people in far Northeastern Siberia and Native Americans.

The statistical tools for analyzing population mixture were developed by Patterson and presented in a systematic way in the report. These tools are the same ones used in previous discoveries showing that Indian populations are admixed between two highly diverged ancestral populations and showing that Neanderthals contributed one to four percent of the ancestry of present-day Europeans. In addition, the paper releases a major new dataset that characterizes genetic diversity in 934 samples from 53 diverse worldwide populations.

"The human genome holds numerous secrets. Not only does it unlock important clues to cure human disease, it also reveal clues to our prehistoric past," said Mark Johnston, Editor-in-Chief of the journal GENETICS. "This relationship between humans separated by the Atlantic Ocean reveals surprising features of the migration patterns of our ancestors, and reinforces the truth that all humans are closely related."

Archaeologists discover shipwrecks, ancient harbor on coast of Israel


A team of archaeologists from the University of Rhode Island, the Israel Antiquities Authority, and the University of Louisville have discovered the remains of a fleet of early-19th century ships and ancient harbor structures from the Hellenistic period (third to first century B.C.) at the city of Akko, one of the major ancient ports of the eastern Mediterranean. The findings shed light on a period of history that is little known and point to how and where additional remains may be found.


The discoveries were presented on November 15 and 17 in Chicago at the annual meeting of the American Schools of Oriental Research by URI assistant professors Bridget Buxton and William Krieger on behalf of the Israel Coast Exploration project.

According to Buxton, three of the four well-preserved shipwrecks found off the coast south of Akko were first detected using a sub-bottom profiler in 2011. Later, storms stripped off several meters of inshore sediments and temporarily revealed the wrecks, as well as an additional large vessel. The wrecks are now reburied.

During the brief time the shipwrecks were exposed, the Israel Antiquities Authority investigated one of them: a 32 meter vessel which still preserved its brass gudgeon (rudder socket) and many small artifacts, such as plates, a candlestick, and even a cooking pot with bones in it. Laboratory analyses completed this summer by the IAA revealed that the ship's wood came from Turkey. The team believes these ships may have belonged to the Egyptian navy under Admiral Osman Nurredin Bey, whose ships were severely damaged in his attempt to capture Akko in the Egyptian-Ottoman War of 1831. The town eventually fell to Egyptian land forces under Ibrahim Pasha in 1832.

"These ships have occasionally been exposed and buried again by storms since we found them," Buxton said. "We're in a race against time to find other ships in the area and learn from them before storms totally dislodge or destroy them."

Although shipwrecks from the 1800s are not the highest priorities in a region where civilization goes back thousands of years, Buxton is excited by the discovery for what it tells her about where much older ships may be found.

"Like many underwater archaeologists I'm very interested in finding a well-preserved example of an ancient multi-decked warship from the Hellenistic age," said Buxton. "These ships were incredible pieces of technology, but we don't know much about their design because no hulls have been found. However, a combination of unusual environmental and historical factors leads us to believe we have a chance of finding the remains of one of these ships off the northern coast of Israel."

Buxton believes that the ships they are looking for are likely buried in the coastal sediment, which has built up over the centuries through natural processes. However, time is not on their side. "That protective silt is now being stripped away," she said. "And it's being stripped away a lot faster than it was originally dumped, by a combination of development, environmental changes, and the effects of the Aswan Dam." The Nile River has historically deposited large quantities of silt in the area, but the dam has significantly reduced the flow of silt.

The archaeologists found the ships and another early modern vessel within Akko's modern harbor while testing their equipment in preparation for an ongoing survey out in deeper water. The sub-bottom profiler detects anomalies below the sea floor. "It's the gift that keeps on giving," Buxton said. "We found so many targets to explore that we didn't have time to check all of them, but even just having information about where things are helps Koby (Jacob Sharvit, director of the IAA Maritime Antiquities Unit) know where to look after any big storms."

One line of buried targets detected off the southern seawall of old Akko is particularly suggestive. Continuing excavations in this area over the summer revealed an alignment between these targets and a newly-discovered slipway and shipshed structure, which continued out under the sea floor 25 meters from the Ottoman city wall. The feature resembles other naval shipsheds found in places such as Athens where they were used to haul up ancient warships. The excavation project was initially undertaken to strengthen the eroding sea wall, but it also revealed Hellenistic masonry, pottery vessels, an ancient mooring stone, and a stone quay 1.3 meters below the modern sea level. The possibility that much more of the Hellenistic port lies well-preserved under the sea floor is exciting for the archaeologists, because it means that shipwrecks from earlier centuries that have so far not been found at Akko may simply be buried deeper down in the sediment.

"We've got fragmentary historic records for this area in the Hellenistic period, and now we've found a very important feature from the ancient harbor. Ancient shipwrecks are another piece of the puzzle that will help us to rewrite the story of this region at a critical time in Mediterranean history," she said.

Located on the northern coast of Israel, the UNESCO World Heritage Site of Akko is one of the few cities in the Mediterranean with more than 5,000 years of maritime history. Also known as Acre, Ake and Ptolemais, its port was an important waypoint for the Phoenicians, Romans, Crusaders, Ottomans and other ancient maritime empires. In the Hellenistic period, it was bitterly fought over by the rival empires of Egypt and Syria.

"Understanding the history and archaeology of Akko's port is crucial to understanding the broader issues of maritime connectivity and the great power struggles that defined the history of the Eastern Mediterranean during the Hellenistic Age," Buxton said.
