Fossil bee nest provides clues to environment of early hominin

Analysis of the first fossil bee nest from the Plio-Pleistocene of South Africa suggests that the human ancestor Australopithecus africanus lived in a dry savannah environment, according to a study* published September 28, 2016 in the open-access journal PLOS ONE by Jennifer Parker from University College London, United Kingdom, and colleagues.

Little paleoecological information is available for the site in South Africa where the first Au. africanus fossil—the ‘Taung Child’—was discovered. However, insect-related fossils, abundant at the discovery site, can yield insights into the paleoenvironment. Bees, for example, tend to build characteristic nests in characteristic conditions. Parker and colleagues analyzed CT scans of a fossil bee nest that was discovered near the Taung Child site to determine its internal structure and thus the kinds of bees that built it.

The fossil nest was exceptionally well preserved, and the structure of its cells and tunnels suggested that it was made by a ground-nesting solitary bee. These bees typically nest on bare, light, dry soil that is exposed to the sun, which bolsters other recent evidence that Au. africanus lived in dry savannahs. Insect-related fossils are common but largely overlooked at sites where human ancestors lived, the researchers said, and their work underscores the contribution such fossils can make to understanding the environments where human ancestors lived.

“When Raymond Dart published his description of the ‘Taung Child’ in 1925 he profoundly changed our understanding of human evolution,” says study co-author Philip Hopley. “In the 90 years following his discovery, attention of anthropologists has moved to other African sites and specimens, and research at Taung has been hampered by the complex geology and uncertain dating. New research at Taung is helping to reconstruct the environment in which this enigmatic little hominin lived and died.”

Humans may have occupied Southern Cone of South America 14,000 years ago

Humans may have occupied the Southern Cone 14,000 years ago, according to a study* published September 28, 2016 in the open-access journal PLOS ONE by Gustavo Politis from CONICET and the Universidad Nacional del Centro de la Provincia de Buenos Aires, Argentina and colleagues.

Previous research has suggested that there were people west of the Andes Mountains at around 14,500 years, and that the Clovis people, a prehistoric Native American group of hunter-gatherers, were not the first humans to arrive in the Americas 13,000 years ago. Now, more recent studies from the Pampas region of Argentina support this hypothesis, and suggest that Homo sapiens, or early humans, arrived in the Americas during a period earlier than the Clovis hunters of North America. The authors of the present study sought to date the earliest human occupation of the Arroyo Seco 2, a rich archaeological site in the Southern Cone, the southern tip of South America.

At Arroyo Seco 2, researchers excavated ancient tools, bone remains from a variety of extinct species, and broken animal bones containing fractures caused by human tools. They used radiocarbon dating techniques to determine the age of the mammal bones, and applied microscopic analysis to the specimens.

The researchers found limb bones from extinct mammals at the site, which may indicate human activities of depositing and transporting animal carcasses for consumption at a temporary camp. They found that the bones of some mammal species were concentrated in a specific area of the site, which could indicate specific areas of butchering activities. Microscopic examination also revealed that some bones contained fractures most likely caused by stone tools. Finally, the material remains found at the site were dated between 14,064 and 13,068 years ago, and thus the authors hypothesize that the Arroyo Seco 2 site may have been occupied by humans during that time. This timeline, along with other South American sites, indicates that humans may have arrived at the Southern Cone prior to the Clovis people, but after the onset of the Last Glacial Maximum, or last glacial period which took place 19,000-20,000 years ago.

While the characteristics of some of these archaeological materials could be explained without human intervention, the combination of evidence strongly suggests human involvement. Humans’ arrival into the Southern Cone 14,000 years ago may represent the last step in the expansion of Homo sapiens throughout the world and the final continental colonization.

Neanderthal and modern human ear bones

A study* explores morphological differences in and functional properties of the ear bones of Neanderthals and anatomically modern humans (AMH). The ear bones, or ossicles, of the middle ear play an important role in auditory function, and while previous studies have identified structural differences between Neanderthal and AMH ear ossicles, the limited number of Neandertal ossicle samples has hampered detailed comparative studies. Alexander Stoessel and colleagues analyzed the ossicles of 14 Neanderthal individuals to investigate the interplay between function and morphology in Neanderthal and AMH ear ossicles. The authors used micro-CT scans and 3D shape analysis to quantify the shape and functional properties of Neanderthal ossicles and the associated tympanic cavity. Comparative analysis of AMH and Neanderthal ear anatomy revealed differences in shape and spatial configuration that the authors attribute to different evolutionary trajectories related to increases in brain size. Despite contrasting evolutionary paths, however, AMH and Neanderthal ossicle morphological differences did not affect the functional properties of the middle ear. According to the authors, the results might be indicative of consistent aspects of vocal communication in AMH and Neanderthals that were preserved and inherited from a common ancestor.

Water sources and human colonization of Australia

Researchers report a network of water bodies across Australia that may have fueled rapid human colonization of the continent 47,000 or more years ago. Considerable archaeological debate surrounds the timing and routes of early human dispersal in Australia, and the distribution of water sources on the continent, particularly in the arid interior, might have played a role in facilitating human colonization of the continent. Michael Bird, Damien O’Grady, and Sean Ulm assessed the spatial distribution and permanency of standing water in the modern Australian landscape to investigate human dispersal on the continent. The Australian Water Observations from Space dataset and data on small permanent water bodies enabled the authors to conduct spatial analysis of 112,786 water bodies. The results indicated a high degree of landscape connectivity during wet periods and a high density of water sources stretching from northern Australia, through semi-arid and arid regions, to southeastern Australia and into the continent’s arid center. Moreover, an analysis representing human travel costs between permanent water bodies situated 84% of more than 30,000-year-old archaeological sites within 20 km of modern permanent water sources. The research also shows that multiple, well-watered routes into the arid and semi-arid interior of Australia would have existed during periods of early human occupation and dispersal. The findings suggest that a series of well-watered routes across Australia could have enabled the human occupation of the continent’s arid interior, according to the authors.

Ancient Charred Hebrew Scroll Virtually Unwrapped

A new digital analysis of the extremely fragile Ein Gedi scroll — the oldest Pentateuchal scroll in Hebrew outside of the Dead Sea Scrolls — reveals the ink-based writing hidden on its untouchable, disintegrating sheets, without ever opening it. While prior research has successfully identified text within ancient artifacts, the Ein Gedi manuscript represents the first severely damaged, animal skin-based scroll to be virtually unrolled and non-invasively read line by line. The series of digitization techniques employed by William Brent Seales of the University of Kentucky and colleagues demonstrates that it is possible to “see” ink-based text within an extremely fragile scroll while avoiding the need for physical handling. The traditional approach of unrolling a scroll and pressing it flat in order to duplicate text is not an option for splintering manuscripts like the Ein Gedi scroll, which has been burned and crushed into lumps of charcoal. Seales, along with a team of researchers, began by performing a volumetric scan of the scroll using X-ray microtomography, followed by segmentation, which digitally creates a “page” containing the writing. The team pieced together over 100 such scanned segments of the scroll by hand. Further manipulation of the digitized scroll involved using texturing and flattening techniques, and finally, virtual unwrapping to unveil the text written on its pages. At last, the authors were able to “see” the text on five complete wraps of the Ein Gedi scroll, and the resulting image is one of two distinct columns of Hebrew writing that contain legible and countable lines, words, letters, and spacing. Further analysis revealed the scroll’s writings to be the book of Leviticus, which makes it the earliest copy of a Pentateuchal book ever found in a synagogue’s Holy Ark. This virtual unlocking of the Ein Gedi scroll paves the way for further scholarly analysis of this and other text buried in delicate, damaged materials.

The Israel Antiquities Authority worked with scientists from Merkel Technologies, Ltd. in Israel, to conduct high resolution 3D scanning of Dead Sea Scrolls fragments and phylactery (tefillin) case using the Bruker Skyscan model 1176 Micro-CT scanner. The fragment of the extensively burned and damaged Ein Gedi scroll was also scanned, after which the scan results were sent to Professor Seales, who had developed a digital imaging software which allowed scientists to virtually “unroll” the scroll and “see” the text. This revealed lines of the first 8 verses of the Book of Leviticus, as follows:

“The LORD summoned Moses and spoke to him from the tent of meeting, saying: Speak to the people of Israel and say to them: When any of you bring an offering of livestock to the LORD, you shall bring your offering from the herd or from the flock. If the offering is a burnt-offering from the herd, you shall offer a male without blemish; you shall bring it to the entrance of the tent of meeting, for acceptance in your behalf before the LORD. You shall lay your hand on the head of the burnt-offering, and it shall be acceptable in your behalf as atonement for you. The bull shall be slaughtered before the LORD; and Aaron’s sons the priests shall offer the blood, dashing the blood against all sides of the altar that is at the entrance of the tent of meeting. The burnt-offering shall be flayed and cut up into its parts. The sons of the priest Aaron shall put fire on the altar and arrange wood on the fire.Aaron’s sons the priests shall arrange the parts, with the head and the suet, on the wood that is on the fire on the altar. (Leviticus 1:1-8).

 

According to Dr. Sefi Porath, discoverer of the scroll in the 1970 Ein Gedi excavations, “The deciphering of the scroll, which was a puzzle for us for 45 years, is very exciting. Ein Gedi was a Jewish village [located near the west coast of the Dead Sea] in the Byzantine period (fourth–seventh century CE) and had a synagogue with an exquisite mosaic floor and a Holy Ark. The settlement was completely burnt to the ground, and none of its inhabitants ever returned to reside there again, or to pick through the ruins in order to salvage valuable property. In the archaeological excavations of the burnt synagogue, we found in addition to the charred scroll fragments, a bronze seven-branched candelabrum (menorah), the community’s money box containing c. 3,500 coins, glass and ceramic oil lamps, and vessels that held perfume. We have no information regarding the cause of the fire, but speculation about the destruction ranges from Bedouin raiders from the region east of the Dead Sea to conflicts with the Byzantine government.”

The date of the Ein-Gedi scroll is still uncertain. Carbon-14 dating suggests that the scroll was created around 300 CE. However, the ancient script style suggests a date arund 100 CE, according to Ada Yardeni, an authoritative expert on Hebrew paleography. 

In addition to the decipherment of the heavily charred ancient Hebrew scroll, it also confirms the first time a Torah scroll was ever found in a synagogue inside a Holy Ark in an archaeological excavation.

Ancient mystery solved: They were Neanderthals

Using ancient protein and DNA analysis to uncover a watershed moment in the origin of modern humans, a study* finds support for a Neanderthal provenance of Châtelperronian stone tools and bone artifacts at the Grotte du Renne archeological site in north-central France. Modern humans are thought to have displaced Neanderthals around 50,000-40,000 years ago in Eurasia. To help settle a debate about this major transition in human evolution, Frido Welker and colleagues performed mass spectrometry analysis of specimens found at the archaeological site of the Grotte du Renne in Arcy-sur-cure, France. Some studies suggest that the Châtelperronian stone tools found at the site can be traced back to the Upper Paleolithic and were made by modern humans, whereas others trace the tools to the preceding transitional period marked by the continued presence of Neanderthals, largely based on morphological identification of hominin remains. The authors identified 28 additional hominin bone specimens at Grotte du Renne that likely belonged to a breastfed infant. Through ancient protein analysis, the authors determined that the hominin specimens belonged to Late Pleistocene Neanderthals, not anatomically modern humans. Direct radiocarbon dating of ancient collagen protein extracted from one of the specimens suggested that the specimen likely dated to the Châtelperronian at the site. The findings reaffirm the association of the Châtelperronian tool-kit and bone artifacts at Grotte du Renne with Neanderthals, according to the authors.

The World’s Earliest Known Use of Indigo Dye Found in Peru

A new study published in Science Advances reports the earliest known use of indigo dye, discovered in an unusually well-preserved, 6,000-year-old Andean cotton fabric from Peru, which retained traces of the blue pigment. The finding predates the earliest reported use of indigo, in ancient Egyptian textiles, by about 1,500 years. When Spaniards arrived in the Americas, they were impressed by Andean weaving and dyeing practices. To date, evidence of the age and complexity of these practices has largely come from cotton textiles found in Huaca Prieta, a large ceremonial mound in Peru first excavated in the 1940s. Previous research suggests that the earliest cotton textiles from this site to feature blue pigment are roughly 6,000 years old, though the source of the blue color on these fabrics has been unknown. Using high-performance liquid chromatography and photodiode-array detection, researchers lead by Jan Wouters, Ana Claro, and Jeffery Splitstoser analyzed a sample of blue yarn from one of the ancient blue-striped fabrics, along with samples of blue yarns from seven other fabrics from the Huaca Prieta. The authors found that the blue in the ancient cotton textiles came from plant-based indigoid dye (indigotin). The results indicate that humans were using indigo to dye textiles as far back as 6,000 years ago, much earlier than ancient Egyptians, who were dying textiles with indigo 4,400 years ago. Other early examples of indigo dye use are known from artifacts in China, where indigo has been positively identified as early as 3,000 years old. It is believed that indigo might have been used earlier in the Near East; however, actual examples with positive identifications of the blue dye are not available, making the indigo found at Huaca Prieta the earliest known and document use of indigo.

Rare Roman gold coin found in Jerusalem

The discovery of a rare gold coin bearing the image of the Roman Emperor Nero at the University of North Carolina at Charlotte’s archaeological excavations on Mount Zion in Jerusalem, has just been announced by the archaeologists in charge of the project, Drs. Shimon Gibson, James Tabor, and Rafael Lewis.

“The coin is exceptional,” said Gibson, “because this is the first time that a coin of this kind has turned up in Jerusalem in a scientific dig. Coins of this type are usually only found in private collections, where we don’t have clear evidence as to place of origin.”

The gold coin (aureus) bears the bare-headed portrait of the young Nero as Caesar. The lettering around the edge of the coin reads: NERO CAESAR AVG IMP. On the reverse of the coin is a depiction of an oak wreath containing the letters “EX S C,” with the surrounding inscription “PONTIF MAX TR P III.” Importantly, these inscriptions help to work out the date when the coin was struck as 56/57 AD. Identification of the coin was made by the historian and numismatist, Dr. David Jacobson from London.

The coin dates to a little more than a decade before the destruction of Jerusalem by the Romans in 70 AD, and was found in rubble material outside the ruins of the 1st Century Jewish villas the team has been excavating. The team has hypothesized that the large houses may have belonged to wealthy members of the priestly caste, and it may have come from one of their stores of wealth.

“The coin probably came from one of the rich 2000-year old Jewish dwellings which the UNC Charlotte team have been uncovering at the site,” said Gibson. “These belonged to the priestly and aristocratic quarter located in the Upper City of Jerusalem. Finds include the well-preserved rooms of a very large mansion, a Jewish ritual pool (mikveh) and a bathroom, both with their ceilings intact.”

This mansion and other like it, were utterly destroyed by Titus and the Roman legions, when Jerusalem was razed to the ground. It is likely, owing to the intrinsic value of the gold coin, it was hidden away ahead of the destruction of the city, and was missed by the marauding and looting Roman soldiers.

“It’s a valuable piece of personal property and wouldn’t have been cast away like rubbish or casually dropped. It’s conceivable that it ended up outside these structures in the chaos that happened as this area was destroyed.”

The image of Nero is significant in that it shows the presence of the Roman occupation and provides a clear late date for the occupation of the residences. There is no historical evidence that Nero ever visited Jerusalem. Tabor pointed out that the coin is dated “to the same year of St. Paul’s last visit to Jerusalem, which resulted in his arrest (on the charge of taking Gentiles into the Temple) and incarceration in Caesarea.” Last of the Julio-Claudian line, Nero was Roman emperor for fourteen years (54-68 AD). He had the reputation for being a tyrant, and some believed he was responsible for the devastating fire of 64 AD, which resulted in the burning of much of Rome.

The archaeological project has brought to light many other significant finds during the 2016 summer season, and work at the site will be resumed next year.

Researchers unearth ancient mythological statues in Jordan

NORTH CAROLINA STATE UNIVERSITY—A team of North Carolina-based researchers helped unearth more clues this summer about the ancient Nabatean city of Petra in Jordan.

As part of a larger excavation at the site, the group of North Carolina State University and East Carolina University faculty and students discovered two marble statues of the mythological goddess Aphrodite — artifacts that dig co-director Tom Parker describes as “absolutely exquisite.”

Parker, a professor of history at NC State, said the team found the pieces while excavating domestic structures in Petra’s North Ridge area during May and June.

“I’ve been doing field work in the Middle East for 45 years and never had a find of this significance,” Parker said. “These are worthy of display at the Louvre Museum or the Metropolitan Museum of Art.”

The statues, which also feature the mythological god Cupid, are largely intact from pedestal to shoulders. Both statue heads and much of their upper extremities were also recovered at the site and will be restored.

This year’s dig marked the third season of the Petra North Ridge Project, an initiative aimed at uncovering clues about the ancient city’s non-elite population. So while the statues are remarkable finds, they’re also somewhat unexpected.

The team was digging what they thought was an ordinary home this summer when they came across something much more. The house was more like an urban villa, Parker said, equipped with its own sophisticated bath house. The team found the fragmented statues next to the home’s staircase.

“Even though they weren’t exactly what we were looking for, these finds still tell us a lot about the population,” Parker said.

The marble statues are Roman in style, which provide additional insight to the cultural impact of Rome’s annexation of Nabataea in 106 A.D. “The Nabateans were true geniuses in many ways, in part because they were ready and willing to assimilate to and adopt elements of other cultures around them,” Parker said. “They adopted a lot of Egyptian culture when they were neighbors. When Romans took over, they were open to Roman influence.”

The dig team, which Parker co-directs with bioarchaeologist Megan Perry, professor of anthropology at ECU, found a wealth of other artifacts that shed more light on Nabatean daily life. Digging one other domestic structure and three rock-cut shaft tombs, the researchers discovered installations for cooking and storage, occupational remains such as pottery and animal bones, an iron sword, ceramic oil lamps and human bones intermixed with personal adornments and jewelry.

“The human remains and mortuary artifacts from Petra provide perspectives not only on Nabataean concepts of death, but also their biological histories while alive,” Perry said.

13th century Maya codex, long shrouded in controversy, proves genuine

PROVIDENCE, R.I. [Brown University]—The Grolier Codex, an ancient document that is among the rarest books in the world, has been regarded with skepticism since it was reportedly unearthed by looters from a cave in Chiapas, Mexico, in the 1960s.

But a meticulous new study of the codex has yielded a startling conclusion: The codex is both genuine and likely the most ancient of all surviving manuscripts from ancient America.

Stephen Houston, the Dupee Family Professor of Social Science and co-director of the Program in Early Cultures at Brown University, worked with Michael Coe, professor emeritus of archeology and anthropology at Harvard and leader of the research team, along with Mary Miller of Yale and Karl Taube of the University of California-Riverside. They reviewed “all known research on the manuscript,” analyzing it “without regard to the politics, academic and otherwise, that have enveloped the Grolier,” the team wrote in its study “The Fourth Maya Codex.”

The paper, published in the journal Maya Archaeology, fills a special section of the publication and includes a lavish facsimile of the codex.

The study, Houston said, “is a confirmation that the manuscript, counter to some claims, is quite real. The manuscript was sitting unremarked in a basement of the National Museum in Mexico City, and its history is cloaked in great drama. It was found in a cave in Mexico, and a wealthy Mexican collector, Josué Sáenz, had sent it abroad before its eventual return to the Mexican authorities.”

Controversial from the outset

For years, academics and specialists have argued about the legitimacy of the Grolier Codex, a legacy the authors trace in the paper. Some asserted that it must have been a forgery, speculating that modern forgers had enough knowledge of Maya writing and materials to create a fake codex at the time the Grolier came to light.

The codex was reportedly found in the cave with a cache of six other items, including a small wooden mask and a sacrificial knife with a handle shaped like a clenched fist, the authors write. They add that although all the objects found with the codex have been proven authentic, the fact that looters, rather than archeologists, found the artifacts made specialists in the field reluctant to accept that the document was genuine.

Some ridiculed as fantastical Sáenz’s account of being contacted about the codex by two looters who took him–in an airplane whose compass was hidden from view by a cloth–to a remote airstrip near Tortuguero, Mexico, to show him their discovery.

And there were questions, the authors note, about Sáenz’s actions once he possessed the codex. Why did he ship it to the United States, where it was displayed in the spring of 1971 at New York City’s Grolier Club, the private club and society of bibliophiles that gives the codex its name, rather than keep it in Mexico? As for the manuscript itself, it differed from authenticated codices in several marked ways, including its relative lack of hieroglyphic text and the prominence of its illustrations.

“It became a kind of dogma that this was a fake,” Houston continued. “We decided to return and look at it very carefully, to check criticisms one at a time. Now we are issuing a definitive facsimile of the book. There can’t be the slightest doubt that the Grolier is genuine.”

Digging in

Houston and his co-authors analyzed the origins of the manuscript, the nature of its style and iconography, the nature and meaning of its Venus tables, scientific data — including carbon dating — of the manuscript, and the craftsmanship of the codex, from the way the paper was made to the known practices of Maya painters.

Over the course of a 50-page analysis, the authors take up the questions and criticisms leveled by scholars over the last 45 years and describes how the Grolier Codex differs from the three other known ancient Maya manuscripts but nonetheless joins their ranks.

Those codices, the Dresden, Madrid and Paris, all named for the cities in which they are now housed, were regarded from the start as genuine, the authors note. All of the codices have calendrical and astronomical elements that track the passage of time via heavenly bodies, assist priests with divination and inform ritualistic practice as well as decisions about such things as when to wage war.

Variations among the codices, as well as the assumption that because manuscripts such as the Dresden were authenticated first made them canonical, fed scholars’ doubts about the Grolier, according to the study. The Grolier, however, was dated by radiocarbon and predates those codices, according to the authors.

The Grolier’s composition, from its 13th-century amatl paper, to the thin red sketch lines underlying the paintings and the Maya blue pigments used in them, are fully persuasive, the authors assert. Houston and his coauthors outline what a 20th century forger would have had to know or guess to create the Grolier, and the list is prohibitive: he or she would have to intuit the existence of and then perfectly render deities that had not been discovered in 1964, when any modern forgery would have to have been completed; correctly guess how to create Maya blue, which was not synthesized in a laboratory until Mexican conservation scientists did so in the 1980s; and have a wealth and range of resources at their fingertips that would, in some cases, require knowledge unavailable until recently.

Use and appearance of the Grolier Codex

The Grolier Codex is a fragment, consisting of 10 painted pages decorated with ritual Maya iconography and a calendar that charts the movement of the planet Venus. Mesoamerican peoples, Houston said, linked the perceived cycles of Venus to particular gods and believed that time was associated with deities.

The Venus calendars counted the number of days that lapsed between one heliacal rising of Venus and the next, or days when Venus, the morning star, appeared in the sky before the sun rose. This was important, the authors note, because measuring the planet’s cycles could help Maya people create ritual cycles based on astronomical phenomena.

The gods depicted in the codex are described by Houston and his colleagues as “workaday gods, deities who must be invoked for the simplest of life’s needs: sun, death, K’awiil — a lordly patron and personified lightning — even as they carry out the demands of the ‘star’ we call Venus. Dresden and Madrid both elucidate a wide range of Maya gods, but in Grolier, all is stripped down to fundamentals.”

The codex is also, according to the paper’s authors, not a markedly beautiful book. “In my view, it isn’t a high-end production,” Houston said, “not one that would be used in the most literate royal court. The book is more closely focused on images and the meanings they convey.”

The Grolier Codex, the team argues, is also a “predetermined rather than observational” guide, meaning it declares what “should occur rather than what could be seen through the variable cloud cover of eastern Mesoamerica. With its span of 104 years, the Grolier would have been usable for at least three generations of calendar priest or day-keeper,” the authors write.

That places the Grolier in a different tradition than the Dresden Codex, which is known for its elaborate notations and calculations, and makes the Grolier suitable for a particular kind of readership, one of moderately high literacy. It may also have served an ethnically and linguistically mixed group, in part Maya, in part linked to the Toltec civilization centered on the ancient city of Tula in Central Mexico.

Beyond its useful life as a calendar, the Grolier Codex “retained its value as a sacred work, a desirable target for Spanish inquisitors intent on destroying such manuscripts,” the authors wrote in the paper.

Created around the time when both Chichen Itza in Yucatán and Tula fell into decline, the codex was created by a scribe working in “difficult times,” wrote Houston and his co-authors. Despite his circumstances, the scribe “expressed aspects of weaponry with roots in the pre-classic era, simplified and captured Toltec elements that would be deployed by later artists of Oaxaca and Central Mexico” and did so in such a manner that “not a single detail fails to ring true.”

“A reasoned weighing of evidence leaves only one possible conclusion: four intact Mayan codices survive from the Precolumbian period, and one of them,” Houston and his colleagues wrote, “is the Grolier.”

Archaeologists excavate a Late Bronze Age settlement in Portugal

As Founder and Editor of Popular Archaeology Magazine, Dan is a freelance writer and journalist specializing in archaeology.  He studied anthropology and archaeology in undergraduate and graduate school and has been an active participant on archaeological excavations in the U.S. and abroad.  He is the creator and administrator of Archaeological Digs, a popular weblog about archaeological excavation and field school opportunities.  

When one thinks of Portugal historically and archaeologically, its colonial heyday typically comes to mind. Along with Spain, England, and other European powers of the 15th through 19th centuries, it had established its foothold well beyond its own borders into lands far distant. 

But there is a much more ancient Portugal — one that extends far back into the Bronze Age more than 3,000 years ago, and even further back into prehistory.   

Kate Leonard, a young archaeologist from Canada, had a brush with this more ancient heritage during the summer of 2016. Take, for example, the peculiar stone she encountered while excavating in her trench at a Late Bronze Age site in the Alentejo plain of the Beja region in the southern part of the country.

“One morning when I arrived on site the sunrise was slanting across the site and I noticed some indentations on one of the larger stones in the trench,” she explains. “As I excavated this stone it became clear that it was decorated with prehistoric cup-marks, intentionally created by someone (or multiple someone’s) and then positioned in the Late Bronze Age structural feature we were revealing. Cup-marked stones, or in Portuguese “rochas com covinhas” – or just “covinhas” for short –are a type of prehistoric decorated stone found across western Europe. They are difficult to date but are certainly prehistoric – Neolithic, Copper Age and/or Early Bronze Age – and have frequently been found reused on later sites, as is the case at Outeiro do Circo.”

Outeiro do Circo is a Late Bronze Age fortified hilltop settlement spread across 17 hectares. Today, it appears as a long narrow hill in a relatively flat agricultural area. Archaeological investigations under directors Miguel Serra, Eduardo Porfirio and supervisor Sofia Eiras of Palimpsesto, Inc., are slowly revealing a major monumental site at this location. The cup-marked covinha, a find of its kind that remains a mystery for archaeologists, suggests an ancient significance associated with the object that has been the subject of competing theories. The curious find is not to distract from the importance of the context, however. 

“This huge area was enclosed by a complex defensive system: a double wall of stone, fire hardened clay and wood was augmented with bastions, ramps, platforms and an exterior retaining wall built on a disused ditch,” says Leonard. “By its size alone it is clear that Outeiro do Circo was an important location in the region. The site is one of the largest settlements of this time period in the Iberian Peninsula.”

Leonard and the archaeology team are currently investigating the interior area of the fortification. Toward that end, they have dug a number of trenches on the hilltop summit and inside its wall enclosure, a part of their goal to better understand what activities or functions were performed within it during the Late Bronze Age (1250 – 850 BC), and to determine how modern agriculture has disturbed the archaeological remains.

The most obvious feature, of course, has been the wall itself, an ancient construction that, according to the archaeologists, must have employed a great deal of labor — and an interesting technique. “Large amounts of clumped burnt clay were uncovered in the area of the enclosing wall,” says Leonard. “These clumps of burnt clay and the locations where they were found indicate to the archaeological team that one method used to strengthen the wall foundation was to set it on fire! To set a wall of this size alight, huge amounts of wood would have been heaved up to the top of the hill from the surrounding countryside. Imagine how a wall of fire on top of the highest point in the landscape would have appeared to a person in the Late Bronze Age! There is no doubt this would have demonstrated the importance and power of the wall-builders to anyone who saw the flames or told the story of what they had seen.”

Perhaps more telling about these ancient people, however, are the small finds uncovered and examined at the site. They could relate a story about the everyday lives of the long-gone inhabitants. “Fragments of pottery from the Chalcolithic to the Roman period have been found on the ground surface at Outeiro do Circo,” continues Leonard, “but by far the most common are those from the Late Bronze Age. In the 3m by 3m trench that I am helping to excavate some very interesting Late Bronze Age pottery fragments have been found that help to shed light on the activities that went on in the settlement. These fragments fill out the narrative of this site with evidence of how long the settlement was in use and details about the everyday life of those who lived there. 

Some fragments found in my excavation trench have small holes in them that were made before they were ‘fired’. These small holes could have been for hanging the vessels by cords for storage or during cooking. I also uncovered a small black pottery fragment that had been shaped into a disc from an already broken piece. From many other ancient examples found across Europe it is likely that this was a gaming piece, used to mark a player’s move in a game now long forgotten. A similar piece found at Outeiro do Circo in a previous season is the only known decorated example from Portugal. Another fascinating find was a small rough fragment with three indents on its surface. This is a piece of a broken strainer that could have been used to make cheese!”

According to what archaeologists have discovered to date, Outeiro do Circo was actually part of a larger Late Bronze Age culture or settlement region within a landscape that hosted other smaller settlements. 

Excavations at the Outeiro do Circo site are ongoing with likely much more work to be done before a clearer picture of the lives of these ancient people, who populated and built settlements in the area long before the Romans arrived, can come to light. Leonard’s time at the location was short-lived, however. She has moved on to Scotland, where she is participating in another excavation as part of a global year-long journey to work at twelve different archaeological sites in 12 separate countries. She calls her project Global Archaeology: A Year of Digs. Outeiro do Circo was the 8th stop on her global trek. 

Popular Archaeology will be following and reporting on Leonard’s worldwide experiences periodically throughout 2016 as she hops from one location to another during her global journey. To continue the work, however, Leonard will need financial support from donors. Readers interested in reading about and supporting her self-directed Global Archaeology crowdfunded project can learn more at gofundme.com/globalarchaeology.

Field Museum scientists unearth centuries-old crocodile stone

FIELD MUSEUM—In the 1960s, a team of excavators uncovered the ruins of the ancient city of Lambityeco (AD 500-850), in what is now Tlacolula de Matamoros, Oaxaca, Mexico. In a recent return to the site, the discovery of a carved stone crocodile by Field Museum archaeologists has provided a key to revising long-held ideas about the site.

During the early excavation, archaeologists unearthed seemingly conflicting evidence. On the one hand, they found a palace with iconic frescoes that indicate the close connections between Lambityeco and nearby Monte Albán, a much larger urban settlement in the region. However, not all of the pieces recovered during this study seemed to fit this narrative. Some of the artifacts showed marked differences with those from Monte Albán. Because of these differences, the archaeological team attributed Lambityeco to a later time period than Monte Albán, an interpretation that stood for decades. Nevertheless, more recent reanalysis of materials from Lambityeco has shown that the site was actually contemporaneous with Monte Albán, leading to new questions.

Over the last four years, new excavations led by Gary Feinman and Linda Nicholas of The Field Museum (in conjunction with Mexico’s National Institute of Anthropology and History) have expanded the investigated area at Lambityeco, and their discoveries have yielded a richer history than was originally thought. When the civic-ceremonial area of Lambityeco was first settled, the public buildings were clearly laid out in a manner closely reflective of that at Monte Albán. Yet, during the occupation, a major reorganization in the use of space occurred in the ceremonial core of Lambityeco. The architecture was remodeled so that it no longer reflected the construction patterns at the larger site. This shift likely reflected a distancing in the relationship between the two Valley of Oaxaca centers.

“During this time period, the relationship between Lambityeco and Monte Albán shifted,” said Field Museum MacArthur Curator of Anthropology Gary Feinman. “The people of Lambityeco began to remodel their buildings and reorient the use of space in order to differentiate themselves from Monte Albán.”

Evidence collected over the past four years has helped illustrate this change. One key feature that changed at Lambityeco was its ballcourt–an important structure for both ceremony and recreation in prehispanic Mesoamerica. In its original design, the ballcourt at Lambityeco, which was discovered by the Museum team in 2015, was laid out in a very similar pattern to the one in Monte Albán: both were constructed with the same orientation and were entered from the north side of the court. However, less than two centuries after the ballcourt was created in Lambityeco, the people sealed its north entrance and created a new stairway on its northeast corner–a major shift from the layout at Monte Albán. At this same time, the frescos in the palaces, excavated in the 1960s, were covered over, and never re-created again.

Another piece of evidence that helps illustrate this change at Lambityeco is a large stone carved on three sides with an image of a crocodile that was discovered during this recent field season. This is the largest carved stone found to date at Lambityeco. Although similar crocodile stones have been found at other sites in the Valley of Oaxaca, this was a unique discovery. Not only was it one of a few carvings of its kind to be discovered still in its prehispanic context, but the Field Museum team also found that the stone was moved from its original location during the long-ago occupation of Lambityeco.

“We believe that this crocodile stone was originally a part of a stairway leading up to a temple at the heart of the civic-ceremonial center of Lambityeco,” said Linda Nicholas, archaeologist at The Field Museum. “However, when the people reconstructed the core area of the site, the entrance to the temple was blocked and the stairway was dismantled.”

The stone was moved so that it leaned against the new façade of the building, where it continued to serve ritual significance, as evidenced by remains of charcoal and ceramics used to hold incense that were deposited right in front of the stone. The stone, when found in this location, was upside down with one of its carved sides completely hidden from view. These observations further indicate that the stone had been repositioned from its original location.

As new evidence continues to accumulate from Lambityeco, questions continue to arise. What caused this political shift between Lambityeco and Monte Albán? What is the full extent of architectural changes made within the city? Although anthropologists continue to work on answering these questions, it seems like one fact remains true. In its short-lived history, Lambityeco was a center of significant importance that still holds many clues to understanding the rich prehispanic history of the Valley of Oaxaca.

Some people enhanced the environment, not degraded it, over past 13,000 years

UNIVERSITY OF WATERLOO—Human occupation is usually associated with deteriorated landscapes, but new research shows that 13,000 years of repeated occupation by British Columbia’s coastal First Nations has had the opposite effect, enhancing temperate rainforest productivity.

Andrew Trant, a professor in the Faculty of Environment at the University of Waterloo, led the study in partnership with the University of Victoria and the Hakai Institute. The research combined remote-sensed, ecological and archaeological data from coastal sites where First Nations’ have lived for millennia. It shows trees growing at former habitation sites are taller, wider and healthier than those in the surrounding forest. This finding is, in large part, due to shell middens and fire.

“It’s incredible that in a time when so much research is showing us the negative legacies people leave behind, here is the opposite story,” said Trant, a professor in Waterloo’s School of Environment, Resources and Sustainability. “These forests are thriving from the relationship with coastal First Nations. For more than 13,000 years –500 generations — people have been transforming this landscape. So this area that at first glance seems pristine and wild is actually highly modified and enhanced as a result of human behaviour.”

Fishing of intertidal shellfish intensified in the area over the past 6,000 years, resulting in the accumulation of deep shell middens, in some cases more than five metres deep and covering thousands of square metres of forest area. The long-term practice of harvesting shellfish and depositing remnants inland has contributed significant marine-derived nutrients to the soil as shells break down slowly, releasing calcium over time.

The study examined 15 former habitation sites in the Hakai Lúxvbálís Conservancy on Calvert and Hecate Islands using remote-sensed, ecological and archaeological methods to compare forest productivity with a focus on western red cedar.

The work found that this disposal and stockpiling of shells, as well as the people’s use of fire, altered the forest through increased soil pH and important nutrients, and also improved soil drainage.

This research is the first to find long-term use of intertidal resources enhancing forest productivity. Trant says it is likely similar findings will occur at archaeological sites along many global coastlines.

“These results alter the way we think about time and environmental impact,” he said. “Future research will involve studying more of these human-modified landscapes to understand the extent of these unexpected changes.”

Evolution of human intelligence linked to blood flow to the brain

In a new research collaboration between Wits research entities – the Brain Function Research Group and Evolutionary Studies Institute – and the Cardiovascular Physiology team in the School of Biological Sciences at the University of Adelaide, previously held views on the evolutionary development of the human brain are being challenged.

The findings of their studies, published today in the Royal Society Open Science*, unseats previous theories that the progression of human intelligence is simply related to the increase in the size of the brain. The research team calculated how blood flowing to the brain of human ancestors changed over time, using the size of two holes at the base of the skull that allow arteries to pass to the brain. The findings, published in the Royal Society journal Open Science, thus allowed the researchers to track the increase in human intelligence across evolutionary time.

Their research found that while brain size has increased by about 350% over human evolution, blood flow to the brain increased by an amazing 600%. The increase in the supply of blood to the brain appears to be closely linked to the evolution of human intelligence where the human brain has evolved to become not only larger, but more energetically costly and blood thirsty than previously believed.

Wits Brain Function Research Group co-author Dr Edward Snelling says: “Ancient fossil skulls from Africa reveal holes where the arteries supplying the brain passed through. The size of these holes show how blood flow increased from 3 million year old Australopithecus to modern humans. The intensity of brain activity was, before now, believed to have been taken to the grave with our ancestors!”

“We believe this is possibly related to the brain’s need to satisfy increasingly energetic connections between nerve cells that allowed the evolution of complex thinking and learning,” said project leader Prof. Emeritus Roger Seymour of the University of Adelaide. “To allow our brain to be so intelligent, it must be constantly fed oxygen and nutrients from the blood. The more metabolically active the brain is, the more blood it requires, so the supply arteries are larger. The holes in fossil skulls are accurate gauges of arterial size.” Seymore suggests that the increasingly energetic connections between the nerve cells “allowed the evolution of complex thinking and learning.”

“Throughout evolution, the advance in our brain function appears to be related to the longer time it takes for us to grow out of childhood. It is also connected to family cooperation in hunting, defending territory and looking after our young,” Ms Bosiocic says.

“The emergence of these traits seems to nicely follow the increase in the brain’s need for blood and energy.”

Reconstructing the 6th century plague from a victim

MOLECULAR BIOLOGY AND EVOLUTION (OXFORD UNIVERSITY PRESS)—Before the infamous Black Death, the first great plague epidemic was the Justinian plague, which, over the course of two centuries, wiped out up to an estimated 50 million (15 percent) of the world’s population throughout the Byzantine Empire—and may have helped speed the decline of the eastern Roman Empire.

No one knows why it disappeared.

Recent molecular clues from ancient plague victims have suggested that plague may have been caused by the same bacterium, Yersinia pestis, which was responsible for the Black Death. But the geographic reach, mortality and impact of the Justinian pandemic are not fully known.

Both information from ancient hosts and bacteria could shed light on the role of plague, which has afflicted mankind for more than 5,000 years.

Now, scientists based in Germany, including Michal Feldman, Johannes Krause, Michaela Harbeck and colleagues have confirmed this by recovering the bacterial culprit from sixth century skeletons found in Altenerding, an ancient southern German burial site near Munich. The Altenerding genome dates back to the beginning of the plague.

They have generated the first high-coverage genome of the bacterial agent responsible for the Justinian plague. In addition to revealing new insights in the molecular evolution of Yersinia pestis since the Byzantine times, the new sequence shows features that could not detected due to the limitations in the coverage of a draft genome previously reported by Wagner*, including 30 newly identified mutations and structural rearrangements unique to the Justinianic strain., as well as correcting 19 false positive mutations.

“The fact that the archeological skeletons which gave these exciting insights were excavated over 50 years ago underscores the importance of maintaining well curated anthropological collections,” said author Michaela Harbeck. “We were very fortunate to find another plague victim with very good DNA preservation in a graveyard just a few kilometers from where the individual analyzed in Wagner et al. was found. It provided us with the great opportunity to reconstruct the first high quality genome in addition to the previously published draft genome.”

Three are located in genes critical to plague virulence: nrdE, fadJ and pcp genes. Their data also suggested that the strain was more genetically diverse than previously thought. How and why the pathogen reached Germany remains a mystery.

These new findings allow the authors to develop guidelines that could help improve the quality and authenticity of genomic data recovered from candidate ancient pathogens. And with plague classified as a re-emerging infectious disease in certain regions, an important historic, high-quality reference resource has been generated to offer insights into key the evolutionary changes, adaptation and human impact of plague.

“Our research confirms that the Justinianic plague reached far beyond the historically documented affected region and provides new insights into the evolutionary history of Yersinia pestis, illustrating the potential of ancient genomic reconstructions to broaden our understanding of pathogen evolution and of historical events,” said research colleague Michal Feldman. “Our reanalysis of previous datasets stresses the importance of following strict criteria to avoid errors in the reconstruction of ancient pathogen genomes.”

How the most famous human ancestor died

UNIVERSITY OF TEXAS AT AUSTIN—Lucy, the most famous fossil of a human ancestor, probably died after falling from a tree, according to a study appearing in Nature led by researchers at The University of Texas at Austin.

Lucy, a 3.18-million-year-old specimen of Australopithecus afarensis—or “southern ape of Afar”—is among the oldest, most complete skeletons of any adult, erect-walking human ancestor. Since her discovery in the Afar region of Ethiopia in 1974 by Arizona State University anthropologist Donald Johanson and graduate student Tom Gray, Lucy—a terrestrial biped—has been at the center of a vigorous debate about whether this ancient species also spent time in the trees.

“It is ironic that the fossil at the center of a debate about the role of arborealism in human evolution likely died from injuries suffered from a fall out of a tree,” said lead author John Kappelman, a UT Austin anthropology and geological sciences professor.

Kappelman first studied Lucy during her U.S. museum tour in 2008, when the fossil detoured to the High-Resolution X-ray Computed Tomography Facility (UTCT) in the UT Jackson School of Geosciences—a machine designed to scan through materials as solid as a rock and at a higher resolution than medical CT. For 10 days, Kappelman and geological sciences professor Richard Ketcham carefully scanned all of her 40-percent-complete skeleton to create a digital archive of more than 35,000 CT slices.

“Lucy is precious. There’s only one Lucy, and you want to study her as much as possible,” Ketcham said. “CT is nondestructive. So you can see what is inside, the internal details and arrangement of the internal bones.”

Studying Lucy and her scans, Kappelman noticed something unusual: The end of the right humerus was fractured in a manner not normally seen in fossils, preserving a series of sharp, clean breaks with tiny bone fragments and slivers still in place.

“This compressive fracture results when the hand hits the ground during a fall, impacting the elements of the shoulder against one another to create a unique signature on the humerus,” said Kappelman, who consulted Dr. Stephen Pearce, an orthopedic surgeon at Austin Bone and Joint Clinic, using a modern human-scale, 3-D printed model of Lucy.

Pearce confirmed: The injury was consistent with a four-part proximal humerus fracture, caused by a fall from considerable height when the conscious victim stretched out an arm in an attempt to break the fall.

Kappelman observed similar but less severe fractures at the left shoulder and other compressive fractures throughout Lucy’s skeleton including a pilon fracture of the right ankle, a fractured left knee and pelvis, and even more subtle evidence such as a fractured first rib—”a hallmark of severe trauma”—all consistent with fractures caused by a fall. Without any evidence of healing, Kappelman concluded the breaks occurred perimortem, or near the time of death.

The question remained: How could Lucy have achieved the height necessary to produce such a high velocity fall and forceful impact? Kappelman argued that because of her small size—about 3 feet 6 inches and 60 pounds—Lucy probably foraged and sought nightly refuge in trees.

In comparing her with chimpanzees, Kappelman suggested Lucy probably fell from a height of more than 40 feet, hitting the ground at more than 35 miles per hour. Based on the pattern of breaks, Kappelman hypothesized that she landed feet-first before bracing herself with her arms when falling forward, and “death followed swiftly.”

“When the extent of Lucy’s multiple injuries first came into focus, her image popped into my mind’s eye, and I felt a jump of empathy across time and space,” Kappelman said. “Lucy was no longer simply a box of bones but in death became a real individual: a small, broken body lying helpless at the bottom of a tree.”

Kappelman conjectured that because Lucy was both terrestrial and arboreal, features that permitted her to move efficiently on the ground may have compromised her ability to climb trees, predisposing her species to more frequent falls. Using fracture patterns when present, future research may tell a more complete story of how ancient species lived and died.

In addition to the study, the Ethiopian National Museum provided access to a set of 3-D files of Lucy’s shoulder and knee for the public to download and print so that they can evaluate the hypothesis for themselves.

“This is the first time 3-D files have been released for any Ethiopian fossil hominin, and the Ethiopian officials are to be commended,” Kappelman said. “Lucy is leading the charge for the open sharing of digital data.”

Isotope study determines fish were more prominent in early Alaskans’ diets

UNIVERSITY OF ALASKA FAIRBANKS—Ice age inhabitants of Interior Alaska relied more heavily on salmon and freshwater fish in their diets than previously thought, according to a newly published study.

A team of researchers from the University of Alaska Fairbanks made the discovery after taking samples from 17 prehistoric hearths along the Tanana River, then analyzed stable isotopes and lipid residues to identify fish remains at multiple locations. The results offer a more complex picture of Alaska’s ice age residents, who were previously thought to have a diet dominated by terrestrial mammals such as mammoths, bison and elk.

The project also found the earliest evidence of human use of anadromous salmon in the Americas, dating back at least 11,800 years.

The results of the study were published today in the Proceedings of the National Academy of Sciences.

DNA analysis of chum salmon bones from the same site on the Tanana River had previously confirmed that fish were part of the local indigenous diet as far back as 11,500 years ago. But fragile fish bones rarely survive for scientists to analyze, so the team used sophisticated geochemistry analyses to estimate the amount of salmon, freshwater and terrestrial resources ancient people ate.

A team led by UAF postdoctoral researcher Kyungcheol Choy analyzed stable isotopes and lipid residues, searching for signatures specific to anadromous fish. The effort demonstrated that dietary practices of hunter-gatherers could be recorded at sites where animal remains hadn’t been preserved.

“It’s quite new in the archaeology field,” Choy said. “There’s a lot in these mixtures that’s hard to detect in other ways.”

Ben Potter, a professor of anthropology at UAF and co-author of the study, said the findings suggest a more systematic use of salmon than DNA testing alone could confirm.

“This is a different kind of strategy,” Potter said. “It fleshes out our understanding of these people in a way that we didn’t have before.”

The study required cooperation between UAF’s Department of Anthropology and the Institute of Northern Engineering’s Alaska Stable Isotope Facility to locate and interpret the presence of salmon remains at the sites. Potter said the process could be a template for how a diverse team of researchers can work together to overcome a scientific obstacle.

“It’s an awesome look at how we can merge disciplines to answer a question,” he said.

Ancient dental plaque sheds new light on the diet of Mesolithic foragers in the Balkans

UNIVERSITY OF CAMBRIDGE—The study of dental calculus from Late Mesolithic individuals from the site of Vlasac in the Danube Gorges of the central Balkans has provided direct evidence that Mesolithic foragers of this region consumed domestic cereals already by c. 6600 BC, i.e. almost half a millennium earlier than previously thought.

The team of researchers led by Emanuela Cristiani from The McDonald Institute for Archaeological Research, University of Cambridge used polarised microscopy to study micro-fossils trapped in the dental calculus (ancient calcified dental plaque) of 9 individuals dated to the Late Mesolithic (c. 6600-6450 BC) and the Mesolithic-Neolithic transition phase (c. 6200-5900 BC) from the site of Vlasac in the Danube Gorges. The remains were recovered from this site during excavations from 2006 to 2009 by Dušan Bori?, Cardiff University.

“The deposition of mineralised plaque ends with the death of the individual, therefore, dental calculus has sealed unique human biographic information about Mesolithic dietary preferences and lifestyle,” said Cristiani.

“What we happened to discover has a tremendous significance as it challenges the established view of the Neolithization in Europe,” she said.

“Microfossils trapped in dental calculus are a direct evidence that plant foods were an important source of energy within Mesolithic forager diet. More significantly, though, they reveal that domesticated plants were introduced to the Balkans independently from the rest of Neolithic novelties such as domesticated animals and artefacts, which accompanied the arrival of farming communities in the region”.

These results suggest that the hitherto held notion of the “Neolithic package” may have to be reconsidered. Archaeologists use the concept of “Neolithic package” to refer to the group of elements that appear in the Early Neolithic settlements of Southeast Europe: pottery, domesticates and cultigens, polished axes, ground stones and timber houses.

This region of the central Balkans has yielded unprecedented data for other areas with a known Mesolithic forager presence in Europe. Dental tartar samples were also taken from three Early Neolithic (c. 5900-5700 BC) female burials from the site of Lepenski Vir, located around 3 km upstream from Vlasac.

Although researchers agree that Mesolithic diet in the Danube Gorges was largely based on terrestrial, or riverine protein-rich resources, the team also found that starch granules preserved in the dental calculus from Vlasac were consistent with domestic species such as wheat (Triticum monococcum, Triticum dicoccum) and barley (Hordeum distichon), which were also the main crops found among Early Neolithic communities of southeast Europe.

Domestic species were consumed together with other wild species of the Aveneae tribe (oats), Fabaeae tribe (peas and beans) and grasses of the Paniceae tribe.

These preserved starch granules provide the first direct evidence that Neolithic domestic cereals had already reached inland foragers deep in the Balkan hinterland by c. 6600 BC. Their introduction in the Mesolithic societies was likely eased by social networks between local foragers and the first Neolithic communities.

Archaeological starch grains were interpreted using a large collection of microremains from modern plants native to the central Balkans and the Mediterranean region.

“Most of the starch granules that we identified in the Late Mesolithic calculus of the central Balkans are consistent with plants that became key staple domestic foods with the start of the Neolithic in this region” said Cristiani.

Anita Radini, University of York added, “In the central Balkans, foragers’ familiarity with domestic Cerealia grasses from c. 6500 BC, if not earlier, might have eased the later quick adoption of agricultural practices.”

The findings are published in the journal Proceedings of the National Academy of Sciences.

One of the most significant Etruscan discoveries in decades names female goddess Uni

SOUTHERN METHODIST UNIVERSITY—Archaeologists translating a very rare inscription on an ancient Etruscan temple stone have discovered the name Uni—an important female goddess.

The discovery indicates that Uni—a divinity of fertility and possibly a mother goddess at this particular place—may have been the titular deity worshipped at the sanctuary of Poggio Colla, a key settlement in Italy for the ancient Etruscan civilization.

The mention is part of a sacred text that is possibly the longest such Etruscan inscription ever discovered on stone, said archaeologist Gregory Warden, professor emeritus at Southern Methodist University, Dallas, main sponsor of the archaeological dig.

Scientists on the research discovered the ancient stone embedded as part of a temple wall at Poggio Colla, a dig where many other Etruscan objects have been found, including a ceramic fragment with the earliest birth scene in European art. That object reinforces the interpretation of a fertility cult at Poggio Colla, Warden said.

Now Etruscan language experts are studying the 500-pound slab—called a stele (STEE-lee)—to translate the text. It’s very rare to identify the god or goddess worshipped at an Etruscan sanctuary.

“The location of its discovery—a place where prestigious offerings were made—and the possible presence in the inscription of the name of Uni, as well as the care of the drafting of the text, which brings to mind the work of a stone carver who faithfully followed a model transmitted by a careful and educated scribe, suggest that the document had a dedicatory character,” said Adriano Maggiani, formerly Professor at the University of Venice and one of the scholars working to decipher the inscription.

“It is also possible that it expresses the laws of the sanctuary—a series of prescriptions related to ceremonies that would have taken place there, perhaps in connection with an altar or some other sacred space,” said Warden, co-director and principal investigator of the Mugello Valley Archaeological Project.

Warden said it will be easier to speak with more certainty once the archaeologists are able to completely reconstruct the text, which consists of as many as 120 characters or more. While archaeologists understand how Etruscan grammar works, and know some of its words and alphabet, they expect to discover new words never seen before, particularly since this discovery veers from others in that it’s not a funerary text.

The Mugello Valley archaeologists are announcing discovery of the goddess Uni at an exhibit in Florence on Aug. 27, “Scrittura e culto a Poggio Colla, un santuario etrusco nel Mugello,” and in a forthcoming article in the scholarly journal Etruscan Studies.

Text may specify the religious ritual for temple ceremonies dedicated to the goddess

It’s possible the text contains the dedication of the sanctuary, or some part of it, such as the temple proper, so the expectation is that it will reveal the early beliefs of a lost culture fundamental to western traditions.

The sandstone slab, which dates to the 6th century BCE and is nearly four feet tall by more than two feet wide, was discovered in the final stages of two decades of digging at Mugello Valley, which is northeast of Florence in north central Italy.

Etruscans once ruled Rome, influencing that civilization in everything from religion and government to art and architecture. A highly cultured people, Etruscans were also very religious and their belief system permeated all aspects of their culture and life.

Inscription may reveal data to understand concepts and rituals, writing and language

Permanent Etruscan inscriptions are rare, as Etruscans typically used linen cloth books or wax tablets. The texts that have been preserved are quite short and are from graves, thus funerary in nature.

“We can at this point affirm that this discovery is one of the most important Etruscan discoveries of the last few decades,” Warden said. “It’s a discovery that will provide not only valuable information about the nature of sacred practices at Poggio Colla, but also fundamental data for understanding the concepts and rituals of the Etruscans, as well as their writing and perhaps their language.”

Besides being possibly the longest Etruscan inscription on stone, it is also one of the three longest sacred texts to date.

One section of the text refers to “tina?,” a reference to Tina, the name of the supreme deity of the Etruscans. Tina was equivalent to ancient Greece’s Zeus or Rome’s Jupiter.

Once an imposing and monumental symbol of authority

The slab was discovered embedded in the foundations of a monumental temple where it had been buried for more than 2,500 years. At one time it would have been displayed as an imposing and monumental symbol of authority, said Warden, president and professor of archaeology at Franklin University Switzerland.

The text is being studied by two noted experts on the Etruscan language, including Maggiani, who is an epigrapher, and Rex Wallace, Professor of Classics at the University of Massachusetts Amherst, who is a comparative linguist.

A hologram of the stele will be shown at the Florence exhibit, as conservation of the stele is ongoing at the conservation laboratories of the Archaeological Superintendency in Florence. Digital documentation is being done by experts from the architecture department of the University of Florence. The sandstone is heavily abraded and chipped, so cleaning should allow scholars to read the inscription.

Other objects unearthed in the past 20 years have shed light on Etruscan worship, beliefs, gifts to divinities, and discoveries related to the daily lives of elites and non-elites, including workshops, kilns, pottery and homes. The material helps document ritual activity from the 7th century to the 2nd century BCE.

Besides SMU, other collaborating institutions at Mugello Valley Archaeological Project include Franklin and Marshall College, the University of Pennsylvania Museum of Archaeology, the Center for the Study of Ancient Italy at The University of Texas at Austin, The Open University (UK), and Franklin University Switzerland.
