Excavated dolmen in Sweden one of the oldest in Scandinavia

UNIVERSITY OF GOTHENBURG—Last summer, archaeologists from Gothenburg University and Kiel University excavated a dolmen, a stone burial chamber, in Tiarp near Falköping in Sweden. The archaeologists judge that the grave has remained untouched since the Stone Age. However, the odd thing is that parts of the skeletons of the people buried are missing.

Skulls and large bones are missing and may have been removed from the grave. We don’t know whether that has to do with burial rituals or what’s behind it,” says Karl-Göran Sjögren.

Now that the researchers have examined the material from the grave, they have found that it contains bones from hands and feet, fragments of rib bones and teeth. But skulls and larger bones such as thigh and arm bones are very few.

“This differs from what we usually see in megalith graves, i.e. stone burial chambers  from the Neolithic period,” Karl-Göran Sjögren explains. “Usually, the bones that are missing are smaller bones from feet and hands.”

Torbjörn Ahlström, Professor of Osteology at Lund University, studied the bone finds. His conclusion is that the bones come from at least twelve people, including infants and the elderly. But the archaeologists don’t yet know why they died.

“We haven’t seen any injuries on the people buried so we don’t think violence is involved. But we are continuing to study their DNA and that will show whether they had any diseases,” says Karl-Göran Sjögren.

Falköping has long been known for its many passage graves dating from a somewhat later period, approximately 3300 BCE. Agriculture reached Falbygden in about 4000 BCE, i.e. about 500 years before the grave in Tiarp was built. In all likelihood, the people buried in the dolmen were farmers.

“They lived by growing grain and keeping animals and they consumed dairy products,” says Karl-Göran Sjögren.

Are the people buried in the grave related?

A number of samples were taken at the excavation last summer, including DNA from the skeletal remains.

“The preliminary DNA results show that the DNA in the bones is well preserved. This means we will be able to reconstruct the family relationships between the people in the grave and we are working on that now,” says Karl-Göran Sjögren.

Falbygden is known for its many traces of people from the Stone Age. There are more than 250 passage graves here, large graves built of blocks of stone.

“But this dolmen is older. It’s about 200 to 150 years older than the passage graves, making it one of the oldest stone burial chambers in Sweden and across the whole of Scandinavia,” says Karl-Göran Sjögren.

There is another thing that makes the grave unique.

“It’s the way it is constructed. There’s a little niche at each end. This is unique for graves in Falbygden,” says Karl-Göran Sjögren.

New research challenges hunter-gatherer narrative

UNIVERSITY OF WYOMING—The oft-used description of early humans as “hunter-gatherers” should be changed to “gatherer-hunters,” at least in the Andes of South America, according to groundbreaking research led by a University of Wyoming archaeologist.

Archaeologists long thought that early human diets were meat based. However, Assistant Professor Randy Haas’ analysis of the remains of 24 individuals from the Wilamaya Patjxa and Soro Mik’aya Patjxa burial sites in Peru shows that early human diets in the Andes Mountains were composed of 80 percent plant matter and 20 percent meat.

The study, titled “Stable isotope chemistry reveals plant-dominant diet among early foragers on the Andean Altiplano,” has been published by the peer-reviewed journal PLOS ONE. It applies methods in isotope chemistry and statistical modeling to unveil a surprising twist in early Andean societies and traditional hunter-gatherer narratives.

“Conventional wisdom holds that early human economies focused on hunting — an idea that has led to a number of high-protein dietary fads such as the Paleodiet,” Haas says. “Our analysis shows that the diets were composed of 80 percent plant matter and 20 percent meat.”

For these early humans of the Andes, spanning from 9,000 to 6,500 years ago, there is indeed evidence that hunting of large mammals provided some of their diets. But the new analysis of the isotopic composition of the human bones shows that plant foods made up the majority of individual diets, with meat playing a secondary role.

Additionally, burnt plant remains from the sites and distinct dental-wear patterns on the individuals’ upper incisors indicate that tubers — or plants that grow underground, such as potatoes — likely were the most prominent subsistence resource.

“Our combination of isotope chemistry, paleoethnobotanical and zooarchaeological methods offers the clearest and most accurate picture of early Andean diets to date,” Haas says. “These findings update our understanding of earliest forager economies and the pathway to agricultural economies in the Andean highlands.”

Joining Haas in the study were researchers from Penn State University, the University of California-Merced, the University of California-Davis, Binghamton University, the University of Arizona and the National Register of Peruvian Archaeologists.

Undergraduate students also had the opportunity to conduct research during the initial 2018 excavations at the Wilamaya Patjxa burial site.

Currently a Ph.D. student in anthropology at Penn State University, Jennifer Chen, the journal article’s lead author and a former undergraduate student in Haas’ research lab, performed the isotope lab work and much of the isotope analysis following the excavations.

“Food is incredibly important and crucial for survival, especially in high-altitude environments like the Andes,” Chen says. “A lot of archaeological frameworks on hunter-gatherers, or foragers, center on hunting and meat-heavy diets — but we are finding that early hunter-gatherers in the Andes were mostly eating plant foods like wild tubers.”

Haas notes that archaeologists now have the tools to understand early human diets, and their results are not what they anticipated. This case study demonstrates for the first time that early human economies, in at least one part of the world, were plant based.

“Given that archaeological biases have long misled archaeologists — myself included — in the Andes, it is likely that future isotopic research in other parts of the world will similarly show that archaeologists have also gotten it wrong elsewhere,” he says.

Haas investigates human behavior in forager societies of the past to better understand human behavior in the present. He leads archaeological excavations and survey projects in the Andes and mountain regions of western North America. To learn more about his research, email Haas at whaas@uwyo.edu.

Paleoclimate reconstructions illuminate intersections between climate and disease in ancient Rome

AMERICAN ASSOCIATION FOR THE ADVANCEMENT OF SCIENCE (AAAS)—High-resolution paleoclimate reconstructions from southern Italy, dating to between around 200 BCE and 600 CE, provide a clearer picture of how climate and disease intersected in ancient Rome. Reconstructions showed that temperature and precipitation became increasingly unstable after ~130 CE, with several cold periods tied to historic pandemic outbreaks such as the Justinian Plague. Paleoclimate proxies can offer insights into how past climate change may have influenced human societies, such as when warm or cool intervals coincided with periods of social development or pandemics. The Roman Warm Period – identified from paleoclimate proxies as an era of unusual warmth between roughly 200 BCE and 150 CE – has been associated with a time of prosperity for the Roman Empire. Alternatively, the onset of the Late Antique Little Ice Age around 540 CE, coinciding with the Justinian Plague, is thought to have played a key role in the empire’s decline. Sparse proxy records have made it difficult to characterize these dynamics in detail. Here, Zonneveld et al.* studied temperature and precipitation records at ~3-year resolution between 200 BCE to 600 CE, using proxy data from marine sediments found in the Gulf of Taranto. They observed stronger climate variability beginning after ~130 CE, marking the apparent end of the Roman Warm Period. Comparing these reconstructions with existing records of infectious disease outbreaks in the heart of Rome, they found pulses of ever cooler and drier conditions coinciding with three major pandemics: the Antonine Plague (~165 to 180 CE), the Plague of Cyprian (~251 to 266 CE), and the Justinian Plague, the first wave of the First Plague Pandemic, which began around 540 CE. An extreme temperature drop – about 3°C cooler than the warmest intervals of the Roman Warm Period – occurred between around 537-590 CE, Zonneveld et al. found, which may have amplified the devastation of the Justinian Plague when it emerged in the region.

Archaeologists unearth record of ancient Assyria’s demise

A team of archaeologists excavating at the site of Ziyaret Tepe in southeastern Turkey discovered a rare and unique cuneiform tablet — one that tells a story of frustration and desperation expressed by an ancient Assyrian official, providing a glimpse of conditions in the Assyrian Empire just before its collapse in the 7th century, B.C.  

Recovered within the remains of what archaeologists have identified as an administrative complex, the clay tablet, small enough to be held in the palm of one’s hand, features, in cuneiform script, a letter written by Mannu-ki-libbali, who was a senior official of the Assyrian provincial capital of Tushan. Tushan was a 7th-century city that governed an area on the outskirts of the Assyrian Empire. In the letter, he responds to an order to assemble a unit of chariotry, but he explains that all of the skilled professionals he needed to accomplish it had already fled the city. He expresses his frustration and resignation with these final statements:   

“How can I command? ….. Death will come out of it. No one will escape. I am done!”

“This letter is unparalleled,” writes the excavation leadership in an article published in Popular Archaeology Magazine. “It can only have been written as the front line drew close to Tushan and the infrastructure of the empire collapsed. As a first-hand account of Assyria in its death-throes it is unique.”

The administrative complex in which the tablet was found also yielded a remarkable archive of cuneiform tablets. Totaling 27, they were discovered in fragments on the floors of the rooms of the complex. “The contents of the tablets include movements of grain, the loan of a slave, lists of personnel, the resettlement of people and a census enumerating military officers and their agricultural holdings,” wrote the excavation leadership about the finds. “But the majority of the tablets deal with transactions of barley – deliveries from outlying farmsteads, loans and payments for rations.”  They span the period from 614 BC to 611 BC — around the time of the the fall of Nineveh. 

“This is the first time that Assyrian administrative texts from this period have ever been found,” stated dig directors Timothy Matney and John MacGinnis. The archive provides a window on the Assyrian world as the Babylonian king Nabopolassar was waging military campaigns against a disintegrating Assyrian empire.

Full-scale excavations at Ziyaret Tepe began in 2000 and lasted for 12 seasons. Located on the upper Tigris river abut 60 km east of Diyarbakir in southeastern Turkey, the site consists of a central mound 30 m high and the remains of a surrounding lower town about 30 hectares in area. The project, which was headed in the field by Prof. Timothy Matney of the University of Akron, Ohio, began with geophysical prospection and ceramic surface collection, and work at the site eventually yielded structural and artifact remains that evidenced a massive provincial capital that flourished for almost 300 years. According to written records, it was founded on a previously occupied site by the Assyrian king Ashurnasirpal II in 882 BC, but was then finally captured by the Babylonian king Nabopolassar in 611 BC. Archaeologists have uncovered a palace, an administrative complex, elite residences, and a military barracks at the site.

“Homo sapiens” arrived in China 5,000 years earlier than thought

CNRS—Our ancestors were already living in the north of present-day China around 45,000 years ago. This discovery, made as a result of research at the Shiyu site by an international team including researchers from CNRS1 , challenges the established timeline of colonization in China by Homo sapiens populations 40,000 years ago.

Located about 20 kilometers from the city of Shuozhou, the Shiyu site is, to date, the oldest archaeological site with evidence of the arrival of modern humans in China. Artifacts discovered, including a perforated disc made of graphite — currently the oldest jewelry item ever found in China — and a bifacially shaped bone tool, present a series of characteristics indicative of a diverse range of cultural influences at the time our species arrived in the region. Analysis of tools made of obsidian, a volcanic rock, also revealed the existence of social networks spread over distances of up to 1,000 kilometers. Scientists believe that interactions between Homo sapiens and indigenous populations, far more complex than archaeologists previously imagined, led to significant genetic and cultural mixing.

These results, published on 18 January in Nature Ecology & Evolution,* shed new light on the global expansion of Homo sapiens and broaden our understanding of human history.

Woolly mammoth’s tusk reveals her migration route, which ends in Alaskan hunter-gatherer camp

AMERICAN ASSOCIATION FOR THE ADVANCEMENT OF SCIENCE (AAAS)—Ancient DNA and isotopic analyses of a female woolly mammoth tusk dated to be 14,000 years old has helped scientists trace her relatives and migration route, from the western Yukon to her final resting place in an early Alaskan hunter-gatherer settlement. Although there is no direct evidence that humans actively hunted this mammoth, the presence of other mammoth remains in and around the camp site suggest that mammoth herds congregated there, Audrey Rowe and colleagues say – and humans may have chosen the site’s location specifically for that reason. The woolly mammoth (Mammuthus primigenius) is an iconic ice age animal, subject to ongoing debates over the causes of its extinction and recent efforts to “de-extinct” it. The species thrived in steppe tundra across northern Eurasia and Beringia (what is now Russia and Alaska) during the last ice age. Humans are thought to have spread across Beringia between 20 and 12 thousand years ago, overlapping with woolly mammoths for at least 1,000 years. Although humans are known to have used these animals for food and raw materials such as ivory, details about whether they actively hunted the giants, and how humans may have affected the animals’ extinction, remain elusive. Here, Rowe et al.* examined a full woolly mammoth tusk among other mammoth remains found at Swan Point – a 14,000-year-old archaeological site in Tanana Valley, central Alaska, thought to have been used as a seasonal hunting camp by early Alaskans. DNA showed that the mammoth was a young adult female, around 20 years old when she died, and was closely related to other mammoths found at the site. Isotope analyses revealed that she likely spent the beginning of her life in what is now northwestern Canada before migrating about 1,000 kilometers northwestward for around 2.5 years, through the White Mountains and eventually into the camp where her tusk was found.

The City Under The Museum: A Pictorial

It rises as the most massive, modern edifice near the great Acropolis of Athens. Located only 280 meters from the Parthenon itself, near the southeastern slope of the iconic rock, it strikes an imposing and contrasting contemporary presence among surrounding structures that represent an earlier time in Athen’s history. Opened to the public in 2009, the Acropolis Museum houses more than 4,250 artifacts and other objects, many of which are exhibited across an internal area of 14,000 square meters. Entering and walking throughout this magnificent space, what profoundly strikes most visitors is the statuary, removed from their original Acropolis locations through time as archaeologists, conservationists and others have worked at the famous summit and the associated ancient remains that still grace much of its slope.

But there is a ‘secret’ to this museum that most visitors don’t know or think about until they actually step upon the museum floors. It lies below the surface. Like viewing through a looking glass, you can see it by peering down through filmy, transparent rectangular sections embedded into the floor, interspersed throughout the museum’s ground floor space. Here you see the remains of ancient structures unearthed through a series of excavations in the area at a site designated by archaeologists as the “Makrygiannis plot”, an urban neighborhood that flourished for centuries in the shadow of the Acropolis.

A Slice of Urban Life in Antiquity

From the 4th century BC to the 12th century AD, people carried out their daily lives in this place. They constructed streets, residences, baths, workshops and tombs. Today, visitors can see only a small part of the entire settlement, the segment that has been exposed intact beneath the new Acropolis Museum construction and the Acropolis Metro Station. The rest has been covered with earth during investigations and excavations, preserved and protected for the future.

What the observer sees today are mostly the better-preserved remains dating from Late Antiquity. Prominent among them are the remains of a luxurious residential mansion complex that included colonnaded courtyards, mosaic floors, a private bath system and latrines. Archaeologists and historians suggest that the residence belonged to a wealthy high-ranking official or local patron with ties to Rome’s imperial court. Other elements of the excavated area include public latrines and private baths, such as the West Bath, of other wealthy citizens.

Notable are remains from the 3rd century B.C., showing a house courtyard where later a workshop was constructed. It features three cisterns, with a terracotta cylindrical pipeline providing fresh water and another pipeline diverting water to the street’s sewer.

Warriors of the Clouds: Kuélap, a Chachapoya Citadel

Freelance writer, researcher and photographer, Georges Fery (georgefery.com) addresses topics from history, culture, and beliefs to daily living of ancient and today’s indigenous societies of Mesoamerica and South America. His articles are published online at travelthruhistory.com, ancient-origins.net and popular-archaeology.com, and in the quarterly magazine Ancient American (ancientamerican.com). In the U.K. his articles are found in mexicolore.co.uk.

The author is a fellow of the Institute of Maya Studies instituteofmayastudies.org, Miami, FL and The Royal Geographical Society, London, U.K. (rgs.org). He is a member in good standing with the Maya Exploration Center, Austin, TX (mayaexploration.org) the Archaeological Institute of America, Boston, MA (archaeological.org), NFAA-Non Fiction Authors Association (nonfictionauthrosassociation.com) and the National Museum of the American Indian, Washington, DC. (americanindian.si.edu).

The Lambayeque region in northern Peru is home to cultures as great as any other that emerged in the country’s Pacific Coast and in the Andes Mountains.

One of them is the Chachapoya, whose history arose east of Chiclayo in the rugged and remote northwestern province of Amazonas, bounded by the Marañón River valley to the north and west, and the Huallaga River to the south and east. Between these large rivers, affluents of the powerful Amazon, lies the Utcubamba valley, where the citadel of Kuélap was built ten thousand feet up in the northern Andes mountains.

The Chachapoyas’ origins are uncertain, but they are believed to have migrated centuries ago, probably from Ecuador’s Amazon rain forest. Moving west, they crossed the mighty and dangerous Marañón (or Atunmayo River), a tributary of the Amazon, whose challenging power made their return hazardous. For this reason and because of their relative isolation, the Chachapoyas are a little-known ethnic group among the ancient societies of the Andes.

The culture appears to have developed sometime between the seventh and ninth centuries (unless otherwise noted, all dates are AD/CE). Sometime after that, at a cultural crossroads that once connected villages on the northeastern slopes of the Andes, the Chachapoyas developed trade with the cultures of the Amazon and with those on the lower western slopes of the Andes. Remains of their ancient villages (ayllus) and structures can be found between the Marañón and the Huallaga rivers.

The timeline of the Chachapoyas (called “Warriors of the Clouds” by scholars for their remote location in the tropical jungle-clad mountains of the northern Andes), points to interactions with the Chimú (900-1470) and other cultures on northern Peru’s Pacific Coast. They were followed by the Quechua (Runasimi) speakers from the central Andes around the late 900s (Lathrap, 1970; Isbell, 1974). The new arrivals cultivated maize on artificial stepped terraces at select elevations, but favored settlement locations on high defensible ridge tops, between seven thousand and eleven thousand feet. The geographic limits for the people we call Chachapoya, however, have never been clearly defined (Bradley, 2005). They were later conquered by the Incas, who appear to have given them the name Chachapoyas, since there is no record of their original name in the local language.

The Citadel

It is during the mid-fifteenth century that the tenth Sapa-Inca, Tupac Inca Yupanqui (1471-1493), the son of the great Pachacuti, conquered the Chachapoyas and forcibly transferred local villagers under the Inca system of forced resettlement of conquered people to other parts of the empire known as mitmaq. Archaeologist Federico Kauffmann Doig (2017) describes a citadel built on two large and leveled platforms on the ten thousand feet high plateau called La Barreta that overlooks much of the Utcubamba river valley. La Barreta is two thousand feet long by five hundred feet wide, narrowing down to less than a hundred feet in parts of its length. A seventy feet high stone wall surrounds most of the plateau.

The citadel’s location, in the area’s cold and windy climate, was ideal as a storage facility for grains, other dry foodstuff and possibly, for short-time storage, dehydrated meat. It was also dedicated to the local animist cult, with buildings for permanent residents such as priests, civic leaders, and service staff. The circular structures were built for storage. They have no openings for either doors or windows; however, several were found to have small access ramps. The cone-shaped roofs were made of natural fibers tied onto a wood frame. There were openings for both access to storage from the top and ventilation at ground level to let in the dry mountain air. The reason for such a large food storage complex was primarily to answer periods of bad crops, among which were those generated by El Niño and La Niña climate events, which periodically decimated coastal and highland cultures. Each farmer may have contributed to a set quantity of products from their crops for storage under a levy or tax system.

Kuélap is built in concentric tiers within which are over five hundred densely packed structures enclosed by the site’s outer wall, which is seventy feet high in its highest section (Narváez, 1996). Within the complex are several groups of circular buildings, as well as five square ones that may have housed administrators and service staff. Among the structures is the Atalaya, a forty-foot-high rectangular stone tower. Located at the northern low end of the plateau, it was a lookout post as well as a bastion from which to defend the site from attack along this lowest part of the ridge (Muscutt, 1993). At the opposite end of the site is an unusual circular structure called the Tintero (inkwell) for its inverted conical shape with sides flaring outward at its top. The neck of the inkwell forms a chimney that can only be accessed from above.

James McGraw, from the San Diego Museum of Man, noticed that the chimney is not fully vertical but deliberately tilted. Its dimensions correlate with the sun at noon on the day of the winter solstice, a key day in Andean rituals for agricultural cycles. At that time, the sun rays shine down the Tintero‘s top opening and projects a beam of light onto its floor. At its bottom were carved stones that may have served to track the movement of the sun, making the structure a solar calendrical observatory (Muscutt, 1993). Geometrical pattern motifs are found on select structures, together with representations of the jaguar and the serpent, both symbols found in most ancient cultures of the Americas. The jaguar is the dominant life-form in most domains by day or night, while the serpent is associated with nature’s rebirth, witnessed by the periodic shedding of its skin (molting).         

When Bandelier (1907) and Langlois (1934) visited Kuélap, they noted that many of the niches in the buildings were used as open graves, for they found human remains on the outside of their walls, making the site both a living and a mortuary community. Even though the context for many of these burials is unknown, recent excavations have revealed the presence of many entombments within the site’s walls. Archaeologist Narváez, after counting over a hundred such burials, concluded that “in reality the outer wall is a cemetery” (1988). Recent excavations suggest that other burials could still be found within the site’s walls. Two trapezoidal entryways, about two hundred feet long and ten feet wide at the entry point, allowed access to the citadel. However, their width narrows down to allow only one person at a time to enter the guarded gate to the central plaza (Narvaez, 1988). A third narrow corridor opens west; it is difficult to access from the outside and was probably used to discard material in a ravine below.

Who built Kuélap is uncertain, for archaeological evidence is scant (Muscutt, 1998). Earlier dates indicate that it might have been originally conceived for defense against the expansion of the Chimú Empire, which exerted control over much of the central highlands (Kauffmann Doig, 1998). The site was likely visible from agricultural fields that lie west of the Utcubamba river. Church and Von Hagen report that many of the large communities that lie to the west of the citadel are in locations directly visible from the site’s outer walls (2007), such as the town of Chillo, in Kuélap’s shadows. The remains within the citadel’s walls were in all probability those of select ancestors of people living in nearby villages. Crandall points out that the social relationship between ancestor remains and living people, was an ongoing set of practices designed to reaffirm social ties to the ayllu or kin group (2012).

Based on Ruiz’s association (1972), the monumental construction and tombs probably began around the year 900. Southern sites, however, such as Gran Pajatén, Los Pinchudos and Revash, in today’s Rio Abiseo National Park, were occupied in Inca times (Bonavia, 1968, Church, Von Hagen, 2008). Other larger regional centers, besides Kuélap, appear to have developed between the eighth and tenth centuries. In the late nineteen-nineties, the area south of Leymebamba received much attention when pre-Columbian chullpas, (mausoleums or funeral houses), were found at Revash, fifty-two miles from Kuélap in the surrounding hills around Gran Pajatén, which may have been built at the height of the Chachapoya cultural florescence in the first millennium.

Karajia     

The citadel is an imposing socio-economic and religious complex, whose purposes were like those of other smaller sites. The common denominator with those sites is the prevalence of ancestor remains, which are found in either a coffin or wrapped up in funerary bundles placed in mausoleums. As Crandal (2012) notes, Chachapoya ontology, akin to other Andean people, was predicated on a collective relationship to ancestors who played an active role in reproducing social life. Coffins are called purunmatshus in the local language and were made to receive a single individual. The erect purunmatshus of Karajia in Luya province, are among the most eminent. They are found in large recesses carved in an abrupt rock face, that creates a rocky overhang, thus shielding them from the rain and helping in their preservation.

Their isolated location and overhang were at times insufficient against birds and rodents. They were studied by Kauffmann Doig and his teams during their field research which spanned from the late-1970s to the mid-2000s. The Karajia purunmatshus were found 985 feet up the rock wall overlooking the Aispacha River, each holding a family member or close relative. The coffins are made of clay mixed with natural fibers set on a wood frame; they portray a human shape that, at over eight feet in their upright position, is impressive.

Their appearance is chiefly due to the modeling of their heads and faces, the only anatomical reference to a human body. Their faces and bodies are painted with yellow, tan, and dark ochre designs that make them appear surrealistic and underline that they are men. Even though a few stands alone, they are commonly found in groups of four to ten standing on a thick mud base.

A space between the line of coffins at Karajia, shows that there were originally eight purunmatshus in the original group, but one of them (No.3), is recorded to have fallen in the river below during the violent 1928 earthquake (Kauffmann Doig, 2002). Above their heads, a mummified human skull was held in place by a spike. Of note, however, is that the skull did not belong to the individual inside the prunmatshu, but is from another party. We have no record of, nor do we know the reason why the mummified skull was placed there. Was it to record the hierarchical status of the departed? Neither do we have a history of the ancestors’ identities who, according to the collective memory of local people, point to ancestors of the mythic Ocspalin, a cacique or chief of the Conila’s ayllu or community, who built the bridge with the people over the Aispacha River. Why were the standing coffins placed in inaccessible locations? It seems that it was not so much to avoid eventual plunder, for at that time ancestors from all segments of society were fearfully respected and so were their resting places. The reason may be linked to the fact that those select ancestors were believed to hold powerful spiritual powers in the “other world.” At times, ancestors may raise the wrath of malevolent forces for the actions of their descendants.

In ancient Peru, the purunmatshus were only used by the Chachapoyas in their territory on the left bank of the Utcubamba river. Kauffmann Doig, in 1986, identified six types spanning from the sophisticated Type.A or Purunmatshu Regio at Karajia, to Types B, C and D, which varied through time and locations. The distinctive feature of B, C and D, is the migration through time of the head, made of compact clay on top of a stocky ovoid body without neck, to the chest and later to the belly. The absence of head applies to the more recent cone shaped Type E, while Type F is referred to as a pseudo-sarcophagus, for it is made of a semi-circular, four-feet-high wall made of clay placed in front of a rock face where, within the enclosure, bundled up mummies were found. In Type A, the mummified body inside was tightly wrapped in fine llama wool blankets in a seating or squatting position (the similarity with Wari mummies is striking), with small ceramics and stone votive items placed between the wrappings and at the feet of the ancestor.

Under the Inca

In mid-fifteenth century, the Chachapoyas were incorporated into the Inca “Realm of the Four Parts” (the Tahuantinsuyu in Quechua), under the “son of the Sun,” the great Sapa-Inca in Cuzco, Pachacuti Inca Yupanqui (1418-1471). Pachacuti organized the kingdom into four regions or suyu: northwest, northeast, southwest and southeast, with Cuzco at the center. His son Topa Inca Yupanqui (1441-1493) would eventually extend the Tahuantinsuyu along the Pacific Coast to today’s western Ecuador, south central Bolivia, northwest Argentina, and most of Chile to the south. But before that, in the mid-fifteenth century the Sapa Inca conquered the powerful Chimú Empire on Peru’s north coast; his army then turned inland toward the Andes. The northeast (antisuyu) territory extended deep into the eastern slopes of the mountain range which was covered by a dense tropical forest. Garcilaso de la Vega (1539-1616) wrote that the Inca invasion of the Chachapoya territory started in the mid-1450s. The invaders went through repeated hard-fought battles in the challenging topography, but the Chachapoyas fought hard and were never defeated. The account does not include Kuélap, which may have been bypassed by the Inca armies. Historical sources relate that by the 1460s, after months of relentless battles and deadlocks, the Chachapoyas had no option but to concede to a bitter peace agreement. In accordance with the empire’s rules of occupation, Cuzco sent civil servants and army officers to oversee the territory’s towns and villages.

Furthermore, under the Inca’s rules of occupation, up to fifty per cent of the younger population was moved as mitmaq’ colonists to distant parts of the empire (Espinoza, 1967), while high ranking Chachapoya women were married to Inca administrators. The mummies of those Inca officials are found in mausoleums with their bundles placed side-by-side with those of Chachapoyas. As Crandal (2012) writes, Chachapoya ontology, akin to other Andean people, was predicated on a collective relationship to ancestors who played an active role in reproducing social life.

Gran Pajatén

A smaller yet prominent Chachapoya site with unique particulars is the ancient city of Gran Pajatén, in the Andean cloud forest. Most sites are found between the Marañón and Huallaga rivers in the Rio Abiseo National Park. Gran Pajatén was discovered by Eduardo Peña Meza (1886-1968), but it was known before to people in surrounding villages and stands 9,350 feet on a five-acre hilltop above the Montecristo River, an affluent of the Abiseo River. Based primarily on architectural evidence, the settlement is unequivocally Chachapoya. The remains of over twenty-six circular stone structures, some with two levels, are built atop terraces with stairways. Initially several of them may have stood some fifty feet high with their high cone shaped roof supported by wood beams and covered with natural fibers (Bonavia, 1969, Davis, 1996).

Gran Pajatén is unique not only for its exceptional architecture, but for the number of symbolic and decorative motifs seen on its structures built in Inca times. Like Kuélap, besides being a religious locus, it was a granary depot and distribution center to answer recurring food scarcities. Unlike Kuélap, however, the site was most significant for its religious influence, attested by structures decorated with stone slates mosaic motifs, among which are human shapes and birds held in place with mortar. By and large, the recurrent patterns of most motifs are salient thematic elements that also bear similarities with Inca and Wari cultures. The walls of the second level of Circular Structure 1 are the most elaborate and best-preserved. The building technique shows finely cut limestone slates jutting out of the walls to create geometric motifs. The exceptions to the use of slates in human motifs are the heads, which were sculpted in the round from sandstone, and embedded in the slate design at the appropriate place through a spike jutting out from the head’s back. Kaufmann Doig notes that the schematic and geometric human figures are essentially those of a female that, as a mythical being, held various symbolic attributes.

The figures are repeatedly shown in a circular frieze that encircles Structure 1 and Structure 2, and singly on other buildings (1986). The main recurring stylized human motif is that of the powerful Pachamama. The earth-mother figure, which is shown in a seating position with legs bent at the knees and thighs spread out, indicates that she is giving birth to both humans and nature’s worlds.

The Pachamamas are found on both structures and are similar but for their stylized headgear. The first headgear is shown as a starlike crown, and may refer to bird feathers, probably those of the macaw from the Amazon. The second headgear is understood to be the wings of a bird of prey, probably that of the hawk, not the condor. The hawk, a foremost actor in the magico-religious beliefs and ceremonies of the cultures of the Andes tropical forest, is also found in other ancient societies. As Kauffmann Doig points out, the Pachamama “is the foremost fertility goddess who presided over planting and harvesting and is found in other cultures of ancient Peru” (2017). The Pachamama is the patron deity of most ayllus or localized social groups, self-defined as ancestor-focused kindred.

It was then believed that, among Pachamama’s abilities, was her ever-present creative powers that sustained life on this earth (1992). Ceramics analysis shows that Gran Pajatén was occupied as early as 200 BC, while stone and ceramics link the structures to early Inca occupation. So far there is no record of human remains, mummified or otherwise. The ancient city, like Kuélap, was a granary depot guarded by a strong force and backed up, it was believed, by powerful ancestors and the deities of another world. As Anselmo Lozano Calderón writes “The ancestral past of Andean and Amazonian cultures was replete with the esthetic and symbolic depiction of their existence, akin to the rhythms of nature, and grounded historically in their faith, their land and magic of the divine” (in Kauffmann Doig, 2017). 

Los Pinchudos                                                       

A day’s walk from Gran Pajatén, at 8,900 feet in the cloud forest, is the site of Los Pinchudos. It is another Chachapoya burial complex located in the  Rio Abiseo National Park, in one of Peru’s northern Andean cloud forests. The site was named for seven mausoleums, two of them badly damaged. Los Pinchudos is notable for the carved wood figures displaying a prominent anatomy. They hang from the outside of the mausoleum’s walls below the stone awnings that protected them from the rain. The name “Los Pinchudos” is from local slang that stands for “the ones with penis.” Sculpted from hard wood, the twenty-inch tall Pinchudos dangle from a wood shaft, integral to the statue, that anchored it into the wall of the burial chamber. No mummies were found, but a few bones and pieces of wool from bundles indicated that the ancestors’ bundles were removed by the Europeans during the 16th or 17th century. The geometric symbolism used in the parietal ornaments is like the ones seen at Gran Pajatén and Gantumarca on the left bank of the Marañón river which, for their architecture, bear a close filiation with those of Los Pinchudos. Over five hundred years ago the five mausoleums were covered with painted clay whose residues were found on the back of one of the figures. We do not know if the Pinchudos mausoleums were each painted red, yellow-ochre, or white (Kauffmann 1980; Morales et al. 2002). The symbolic significance of colors was important associated with corresponding rituals, but those are unknown. Unlike purunmatshus made for one person, mausoleums harbored several mummified individuals each tightly wrapped in a bundle.

Mummies and Mausoleums

Mummies and burials are rooted in people’s cultural and spiritual faith in a finite geographical environment. As for most cultures, those roots are primarily defined by language, traditions, and a common belief, which secure their “right of blood” to the soil where they were born and where their ancestors are buried, as opposed to the “right of land” claimed by invaders. In ancient Peru, mummification, or preservation of family members, rested on the belief that their death would be like their past life. They had no expectations about a paradise or a hell, a concept associated with Christianity that arrived with the Spaniards in 1532. Mummification was an ancient practice in Peru: witness the 420 mummy bundles from the Paracas Necropolis, 300-200BC (Tello, 1949). The process of mummification varied through time and place and followed strict imperatives beyond rituals, which were dependent on those of the local environment. In the case of Paracas, the area was, and still is, a dry desert with little humidity coming from the Pacific Ocean.

For the Chachapoyas and other cultures of northwestern Peru, however, the humidity factor was important in the process applied to preserving human remains. Trained people were probably members of shamanic fraternities of either gender, that may have been attached to the priesthood, and were dedicated to the task. The process required dehydration of the body in a cold, dry and well-ventilated location where the removal of the viscera and cleaning of the abdominal cavity took place. Organs in the thorax were not removed, nor were the eyes and brain. Organic substances such as ginger, other roots, and coca leaves were mixed in a light corn paste, which was then used to thoroughly clean and embalm the body. Cotton plugs, and a variety of plant leaves were introduced into the nose cavities as well as in the mouth, to preserve the appearance of the departed. The process was so skillful that the eyes’ sclera was preserved. The body was then placed in a tightly flexed seating position with legs and arms tied up against the body, the hands placed over the face. Each finger was wrapped before the body was tightly bundled up in fine llama wool fabrics. Between the wrappings were placed votive figurines or small items cherished by the departed. The bundle was then placed in a cold, dry and well-ventilated location for several weeks or months before being transferred permanently to its last resting place.

Mausoleums such as those seen at Revash, are called “house of the departed” in Quechua (Runasimi), and do not show Inca influence in their architecture. These funerary structures referred to as pukulio or tshullpas are known throughout Peru spanning from the Wari (500-1000) to the Chimú (900-1450). The Chachapoya mausoleums were built in an existing open corridor in the rock face that was enlarged and extended. The walls of the small structures are made of shaped stones set with mortar with a symbolic “roof.”

The roofs over the structures were of the gable or lean-to type but were not necessary since the tshullpas were already protected by the rocky overhang. According to local folklore, the roofs were made for ancestors to “feel at home.” Built close together, the mausoleums look like a little village, their walls covered with mud of a tan color.

Not so inaccessible as the purunmatshus, over time the tshullpas were visited by people that damaged the mummies’ bundles in search of valuables. Unlike at Karajia, however, the mausoleums are collective with remains of select individuals of the same or extended family, for as in other parts of the Americas, not all progenitors qualified as ancestors. Revash’s distinctive features are symbolic figures painted red on the structures and on the rock face above the mausoleums, such as human shapes, local camelids (llama), and geometric motifs.

In most cultures of the Americas, red pigment is associated with blood, the stream of life. Cinnabar, a red pigment oxide powder, was used in burials, for it was believed to protect the departed soul’s “divine substance” and ward off malevolent forces while it traveled through the underworld. Other architectural particulars are cruciform shapes. Today, in ancient and traditional cultures in the Americas, the equilateral cross openings in structures or painted on ceramics, depict the four changing cardinal directions of the spiritual universe associated with their respective twenty deities and colors, such as red, yellow, black, and white for the Mayas. The equilateral Inca chakama cross holds the same symbolic significance. Each of the twenty right angles of the cross carries its own deity, while the steps between each arm of the cross are representative of andenes or terraces built in steep mountain slopes. Of note is that only funerary bundles of ascendant lineage members worthy of being venerated, were placed in mausoleums or in a purunmatshu. Many mausoleums dot the Chachapoya landscape such as Tingorbamba-Pueblo de los Muertos, La Petaca-Diablo Huasi, Laguna de los Condores and Huabayacu, among many.

* * * * * * * * *

One wonders why human remains have been so important to all cultures. Veneration of ancestors is found in the Pre-Pottery Neolithic (PPN-A,12,800-8,500BP), and much farther back in time. We have seen this concern at Kuélap, Los Pinchudos, and Revash among other sites in the Chachapoya landscape. As Paul Cornerton points out, repetitive rituals act as a mechanism to create communal memory (1989), and one should add identity. Constant to most ancient and traditional cultures today, is the belief in the permanence of life beyond life, hence the prominence given to forefathers believed to help in relieving the pains of life’s here and now.

The shape of funerary bundles recalls plant seeds about to sprout from their shells and was commonly associated with the rhythm of the seasons and the belief in an eternal return. As McAnany reminds us, “the cult to ancestors was integral to the cosmologies and traditions of most cultures in the Andean region and is well documented in those of Mesoamerica” (1995).

The phases of places and divinities follow the same fate as that of people, appearing and disappearing on the scene of life. The sixth Sapa-Inca of the Hanan dynasty, Huayna Capac (1464-1524), had two sons, Atahualpa (1502-1533), born in Ecuador and Huascar, born in Cuzco (1503-1532). Huayna Capac unwisely divided the empire between his two heirs. The northwest and the northeast were assigned to Atahualpa, while the southwest and the southeast, with Cuzco at the center of the realm, were allocated to Huascar. The decision proved deadly to the Inca empire. As expected, the brothers were soon at war with each other. The Chachapoyas in the northeast were drawn into the crossfire, and factions arose with some leaning toward Huascar, while others sided with Atahualpa. A major battle took place in the upper Andes that took the lives of over six thousand Chachapoya warriors. This tragedy so angered the population against Atahualpa, that it rose from rage to a full-fledged revolt. This massacre turned the Chachapoya population against the victorious Atahualpa, who exacted vengeance by killing their leaders and ordered all adolescents of both sexes deported to other parts of the empire (Keith Muscutt, 1998). Kuélap may have been bypassed by the Inca army because it might not have been militarily relevant at the time. Of note, however, is that more than 2,500 stones for slings were stashed in the Atalaya square tower, indicating that the citadel’s defenders were ready to fight off invaders. Large clumps of burnt roofing thatch, however, indicate that residents either burned the structures when the site was abandoned for unknown reasons, or that Kuélap came to a violent end. Whatever the outcome, for the next five centuries, remains of the ancestors buried in its walls were the citadel’s sole occupants.

The Watery Wonders of Ancient Rome

Professor Frank J. Korn has retired from his teaching position on the Classical Studies faculty at Seton Hall University.  He is a Fulbright Scholar at the American Academy in Rome and the author of nine books on various aspects of the Eternal City.  He is listed in Marquis Who’s Who as “a notable classical educator and writer.”  Recipient of the Princeton Prize for Distinguished Teaching, he resides with his wife Camille in Scotch Plains, N.J.  The couple’s three sons –  Frank, Ronald, and John and their families live nearby.  His latest book    Below Rome, the Story of the Catacombs    which he co-authored with his wife, is available on Amazon or from the publisher, St. Johann Press, Haworth, N.J.

Engineering miracles. That is what the ancient Romans should best be remembered for. 

Many other nations of antiquity assembled mighty armies that conquered far and wide. Many raised imposing architecture that dazzled the eye. But none could hold a candle to Rome’s mind-boggling achievements in engineering, particularly when it came to managing water.

When an oracle warned that a certain enemy would never be defeated as long as there was water in Lake Albano, Roman hydraulic engineers simply drained the lake bone-dry, paving the way for the vaunted legions to overcome the Veiians.  Whenever the imperial government had an unwanted river on its hands, the corps of engineers would merely re-route the stream and fling it over some handy cliff. When a greater water supply was needed to accommodate a rapidly expanding population, the same genius would design pipelines to reach out great distances to snatch water from pure mountain streams and bring it rushing down into the City on the Tiber. Since the pipelines would lead (duct) water (aqua) from one place to another, they were given the name “aqueducts.”

Watering Rome

By 312 B.C. the city’s population had reached such numbers that its previous sources of water    natural springs, wells, cisterns, and the Tiber    no longer sufficed. Thus it was in that year that Appius Claudius, as censor, gave old Rome the first of its eventual eleven aqueducts.  (Censors were responsible not only for safeguarding public morals but also for authorizing and supervising public works.) Actually, it was a co-censor, Gaius Plautius, who discovered the mountain stream and planned the pipeline that would channel the water into the city.  But he retired from the elective office before the start of work on the plan, leaving Appius to oversee the construction and completion of the project and to give it his name. This pipeline, the Aqua Appia, redirected some of the water from a spring in the Alban Hills, ten miles to the south, down into the southern corner of Rome, more precisely into the “Greek quarter,” in the valley between the Aventine and Palatine hills.

In 273 B.C. another aqueduct was added, this one drawing its supply from the River Anio that rushes tumultuously down from the Sabine Mountains, about thirty miles east of Rome. (Originally called simply “Anio” it took on the name Anio Vetus (old) when a second aqueduct, drawing from another stretch of the same river, was completed, earning the name Aqua Anio Novus (new). A century and a half later, a public official named Marcius Rex gave Rome the Aqua Marcia. “The dearest of all streams on earth, unsurpassed in coolness and salubriousness, a true gift of the gods to Rome,” was how Pliny the Elder enthused over it.

This was a very ambitious undertaking. Stretching for fifty-six miles, it came with a final price tag of just under 180,000,000 sesterces i.e. about nine billion of today’s U.S. dollars. It supplied enough water to nourish nine of the fourteen precincts into which Rome was later divided by Caesar Augustus.

The year 125 B.C. saw the completion of a fourth water-works, the Aqua Tepula, so called for the tepid temperature of its stream (62 degrees Fahrenheit). This, however, was not fit for drinking. Incidentally, there are many under the impression that the aqueducts’ use was strictly for slaking the thirst of the populace. The fact is that the water also supplied the public baths and gardens, nymphaea, spectacular monumental fountains that were solely for the city’s esthetics, and private homes and villas of the very wealthy. Any overflow went toward flushing latrines and sewers.

During the reign of Augustus, a feverish building boom resulted in new urban problems, one of which was an inadequate water supply. In consultation with his chief adviser, Marcus Agrippa, the emperor commissioned the construction of the Aqua Virgo.  This pipeline provided deliciously pure spring water from about nine miles to the east, up toward Tivoli. It is about a meter and a half in width and was built primarily to furnish the water for the Baths of Agrippa, a sumptuous spa in the section of Rome called, since ancient times, the Campus Martius. (Virgo is Latin for “virgin.” Agrippa so named the facility because one day a lovely young girl is said to have shown a company of his soldiers, parched with thirst, the location of the spring.)

The wonderful British writer H.V. Morton once had the opportunity to visit the site of Aqua Virgo’s source and tells this charming anecdote:  “I was watching these very waters rushing by, knowing that twenty-four hours from now [that’s how long it took for the channeled water to reach the City] they would form the cascades of the fabled Fountain of Trevi and be the subject of hundreds of photographs snapped by an army of wide-eyed tourists.”

The Augustan era also saw the addition of two more aqueducts, the Aqua Julia, which tapped into a cool mountain stream about fifteen miles out from Rome, up above the picturesque hill-town of Grottaferrata; and the Aqua Alsietina, which drew from aquifers near Lake Bracciano, some thirty two miles or so to the north, toward the old, still walled-in Etruscan city of Viterbo. The water, however, was non-potable and used for the naumachia (an artificial lake for mock naval battles) in the trans Tiber district.

So big was this business becoming that by the late first century a full-blown Water Bureau, with offices adjacent to the Roman Forum, was established. This was headed by a commissioner with what today would be considered “cabinet status.” One of the most distinguished of these department heads, or Curatores Aquarum, was Sextus Julius Frontinus. Appointed by the Emperor Nerva in A.D. 96 and re-appointed by Trajan in 98, Frontinus wrote De Aquis Urbis Romae, a technical manual on Rome’s waterworks that is most instructive on the techniques of aqueduct-building. In the preface, he thanks and praises the man who gave him the prestigious post:

“Nescio diligentiore an amantiore rei publicae imperatore Nerva Augusto….

“I do not know anyone who is more diligent, or who loves the State more, than the emperor Nerva Augustus.”

Frontinus goes on to say that since the position had always been assigned to the most outstanding men of the community,  per principes semper civitatis nostrae viros,” and since the task of the Water Commissioner involves the health and well-being and even the safety of the city, “ad salubritatem atque etiam securitatem urbis pertinens,” he takes the office entrusted to him with the utmost sense of commitment and seriousness.

Form and Function

Such an abundance of water was the fruit of the hydrogeological character of the hilly and mountainous territory surrounding Rome, containing cascading streams by the hundreds. First of all, the source of an aqueduct has to be higher than its destination. Some of the streams originated from over a thousand feet above sea level. Each pipeline    in order to function effectively    had to maintain a slight slope to assure that the downward flow of the water retained its velocity continuously to the destination.Thus the whole enterprise depended not on pumping stations but on gravity.

The conduit was mostly underground. En route to the city there were hills that had to be penetrated. When confronted with valleys and lowlands the water channel had to be borne aloft by arch-supported bridge-like structures, the ruins of which, in some instances, still grace the Roman Campagna. This segment of an aqueduct consisted of a flat-bottomed channel, about three feet wide and five feet deep, and was open to the sky, hence vulnerable to debris and clogging. Such “bridges” maintained a steady gradient.

These waterworks were therefor not only wonders of engineering but also masterpieces of architecture, as Vitruvius points out in his book, “De Architectura”. The French writer Chateaubriand, on his grand tour of Rome, marveled that the ancient aqueducts had brought water to the Eternal City “on arches of triumph.”  One need only visit Nimes in France and view the Augustan era Pont du Gard spanning the Gardon River, at the giddy height of a hundred and sixty feet, to agree with both authors; or travel to Segovia in Spain to observe its soaring, remarkably preserved Roman aqueduct. (There were eventually hundreds of aqueducts across the far-flung Empire.)

The earliest of Rome’s aqueducts had pipelines generally of lead, which created difficulties in soldering and/or welding. The builders ultimately had to resort to using terracotta conduits, coated in a smooth-surfaced volcanic cement called pozzolana.

With most aqueducts the water of a stream or spring was first led into a nearby concrete “springhouse”, thence into the main pipeline. The course of it finished    in the city    in a “castello,” which was a massive, towered structure containing one or more chambers of decantation and a vast reservoir from which the water was redistributed into smaller urban conduits.

As for maintenance, there were crews made up of slaves and plebeians, with only the latter, of course, getting a “paycheck.”  These workers, called aquarii, had to deal with problems such as leakage, loose debris and soil blown up by winds and storms, clogging by calcium carbonate deposits that narrowed the walls and had to be scraped away, and illegal tappings by farmers and vineyard owners whose lands happened to be hard by the route of the aqueduct. (Despite the strict laws and severe penalties against such mischief, it somehow persisted)

As for security, there were guards and patrols, night and day, at the source site and at other vulnerable areas. The fact that an aqueduct ran either underground or up on arches, a hundred feet high or more, was in itself a built-in form of security.

For private property owner subscribers the water bills became major headaches. Still, they paid willingly for the luxury. Indeed, there was quite a long waiting list for the service. In one letter, the satirical poet Martial gripes about getting the runaround from the haughty bureaucrats after applying for a pipeline to his estate. Yet, Martial’s allegations aside, a position at the waterworks was not the usual political sinecure. There were no, so to speak,”water-cooler jobs” to be had. The clerks, engineers, mechanics, masons, and unskilled laborers were kept busy all hours of the day and night with complaints of pressure failure. More woes were caused by the periodic necessity of shutting off the pipelines to clean them of their lime deposits.

In A.D. 38, the mentally unbalanced Caligula ordered work to begin on a new aqueduct that would bring water from springs near Subiaco, about forty miles east of Rome. Taking fourteen years to construct, it was completed in the reign of Emperor Claudius, who gave it the name Aqua Claudia. The most important of all these ancient Roman projects, it was called “Magnificentissima” by Frontinus. Underground for the most part, it went overland on a series of sturdy lofty arches for its last nine miles, ending with excellent pressure up on the Caelian Hill. It was later extended across a valley to the Palatine Hill so that it could serve the imperial palace and grounds. In A.D. 1587, Pope Sixtus V utilized what remained of it to construct an up-to-date facility which he called the Aqua Felice. (His given name was Felice Peretti.) Today it nourishes the zones of the Esquiline, Quirinal, and Viminal hills but is largely utilized for the splendid fountains of the city’s historic center, including the terminus: The Fountain of Moses.

On the subject of restoration, it was another pontiff, Pope Paul V, who got the Aqua Traiana up and running again, renaming it, naturally, the Aqua Paola. Emperor Trajan had this aqueduct built in the year 119, drawing its water from springs up in the Sabatini mountains to the north, over a course of nearly forty miles. In our time, as it did in antiquity, it still services the Janiculum Hill and trans Tiber district below it. (That quarter of the city is today’s colorful, ever popular, Trastevere.) The terminus of this waterway is the immense    and immensely beautiful    Fontana Paolina with its five cascades, a name which inadvertently honors both the architect (Domenico Fontana) and the patron (Paul).

Besides the Claudian and Trajanian works, two others were rehabilitated by popes: the Aqua Marcia by Pius IX (who renamed it Aqua Pia), and the Virgo by Nicholas V.

(What necessitated these later restorations was the result of the A.D. 537 Ostrogoth siege of Rome, thirsting the Romans into submission by cutting the aqueducts and choking off the water supply. When the dust finally settled after the last barbarian invasion, Rome deteriorated into a veritable, uninhabitable ghost town, its population dwindling from a peak of a million at the height of the imperial era to a scant fifteen thousand through the early Middle ages.)

The last of the eleven aqueducts of Republican and Imperial Rome was built by order of Emperor Alexander Severus in A.D. 226 and bore his name: Aqua Alexandrina. Its source was a number of springs in the Sassolello Hills, twelve miles north, near the old city of Gobi. Its main purpose was to provide the water for the Neronian Baths.

The great historian Edward Gibbon paid this eloquent tribute to these civil engineering wonders:  “The boldness of the enterprise, the solidity of the execution, and the uses to which they were subservient, rank the aqueducts among the noblest monuments of Roman genius and power.”

For the Romans of antiquity, these endlessly astonishing hydraulic projects exponentially improved the quality of life    and hygiene. Their hauntingly romantic ruins speak in silent eloquence of the grandeur of long-ago Rome, which even as long ago as its heyday had already acquired two popular and poetic nicknames:  Urbs Aeterna (The Eternal City) and Caput Mundi (The Capital of the World).  When those eleven mighty aqueducts were in their prime, they bestowed on Rome yet another sobriquet:  Regina Aquarum …”Queen of the Waters.”

Discovered in the Upper Amazon: 2500-year-old landscape providing evidence for early urbanism in the region

AMERICAN ASSOCIATION FOR THE ADVANCEMENT OF SCIENCE (AAAS)—A dense system of pre-Hispanic urban centers, characterized by constructed platforms and plazas and connected by large, straight roads, has been discovered in the upper Amazon, according to a new study*. The research, based on more than 20 years of interdisciplinary research, suggests that this original 2500-year-old society constitutes the earliest and largest low-density agrarian urbanism documented in the Amazon thus far. Such extensive early development in the Upper Amazon resembles similar Maya urban systems in Central America. Although a growing body of research has begun to highlight the scope and scale of pre-Hispanic occupation of the Amazon, evidence for large-scale urbanism has remained elusive. Stéphen Rostain and colleagues present evidence for an agrarian-based civilization that began more than 2500 years ago in the Upano Valley of Amazonian Ecuador, a region in the eastern foothills of the Andes. Based on more than 20 years of interdisciplinary research that included fieldwork and light detection and ranging (LIDAR) mapping, Rostain et al. describe urbanism at a scale never before documented in Amazonia, consisting of more than 6000 anthropogenic rectangular earthen platforms and plaza structures connected by footpaths and roads and surrounded by expansive agricultural landscapes and river drainages within the 300 square kilometer survey area. The authors identified at least 15 distinct settlement sites of various sizes based on clusters of structures. However, according to Rostain et al., the most notable elements of this built environment are the extensive and complex regional-scale road network connecting urban centers and the surrounding hinterland. Archaeological excavations indicate that the construction and occupation of the platforms and roads occurred between ~500 BCE and 300 to 600 CE and was carried out by groups from the Kilamope and later Upano cultures. Rostain et al. note that the Upano sites are different from other monumental sites discovered in Amazonia, which are more recent and less extensive. “Such a discovery is another vivid example of the underestimation of Amazonia’s twofold heritage: environmental but also cultural, and therefore Indigenous,” write Rostain et al. “…we believe that it is crucial to thoroughly revise our preconceptions of the Amazonian world and, in doing so, to reinterpret contexts and concepts in the necessary light of an inclusive and participatory science.”

Discovery of immense fortifications dating back 4,000 years in north-western Arabia

CNRS—The North Arabian Desert oases were inhabited by sedentary populations in the 4th and 3rd millennia BCE. A fortification enclosing the Khaybar Oasis—one of the longest known going back to this period—was just revealed by a team of scientists from the CNRS1 and the Royal Commission for AlUla (RCU). This new walled oasis is, along with that of Tayma, one of the two largest in Saudi Arabia. While a number of walled oases dating back to the Bronze Age had already been documented, this major discovery sheds new light on human occupation in north-western Arabia, and provides a better grasp of local social complexity during the pre-Islamic period.

Cross-referencing field surveys and remote sensing data with architectural studies, the team estimated the original dimensions of the fortifications at 14.5 kilometres in length, between 1.70 and 2.40 metres in thickness, and approximately 5 metres in height. Preserved today over a little less than half of its original length (41%, 5.9 km and 74 bastions), this colossal edifice enclosed a rural and sedentary territory of nearly 1,100 hectares. The fortification’s date of construction is estimated between 2250 and 1950 BCE, on the basis of radiocarbon dating of samples collected during excavations.

While the study* confirms that the Khaybar Oasis clearly belonged to a network of walled oases in north-western Arabia, the discovery of this rampart also raises questions regarding why it was built as well as the nature of the populations that built it, in particular their relations with populations outside the oasis.

This archaeological discovery, whose results will be published on 10 January in the Journal of Archaeological Science: Reports (JASREP), paves the way for major advances in understanding the prehistoric, pre-Islamic, and Islamic past of the north-western Arabian Peninsula.

The Pompeii of Bronze Age Greece

It would be no exaggeration to say that this ancient city could be described as the Pompeii of Bronze Age Greece. Devastated during the massive eruption of the Thera volcano in the 16th century BCE, like the cities of Pompeii and Herculaneum in present-day Italy many centuries later, it was destroyed yet miraculously preserved, as if frozen in time. Excavated thousands of years after the Thera eruption, it has joined the world’s short-list of the most spectacular archaeological discoveries of all time…. 

Akrotiri of Thera

The Mediterranean Greek island of Santorini, anciently known as Thera, hosts an estimated 2 million visitors a year. As an island in the southern Aegean Sea, it lies about 120 miles southeast of the Greek mainland. It is the largest island within an archipelago of the Cyclades, a group of islands south of Greece and north of Crete. It is best known for its volcanic history, and the great, water-filled caldera that bestows the location its defining characteristic. It is also known for its many attractions as a tourist destination, but perhaps most fascinating of all are the incredible archaeological remains of the nearly 7,000-year-old settlement of Akrotiri, the center of a maritime Cycladic civilization that flourished most prominently during the 16th century BCE. Trade relations established with other Aegean cultures and civilizations that ringed the Mediterranean proved to be the engine of its growth, especially that of the copper trade. It became an important center for processing copper, based on the artifacts discovered at the site. The city prospered as a major center for at least 500 years. Excavations have revealed—along with thousands of artifacts—paved streets, an extensive drainage system, sophisticated pottery, and a masterful array of some of the earliest fresco wall paintings of the Bronze Age. In fact, the culture of Akrotiri was so sophisticated for its time that some historians and scholars have attributed the ancient city as a possible historic basis for the later legend of Plato’s lost Atlantis. The city came to its end between 1620 and 1530 BCE with the eruption of the Thera volcano. 

Here is a sneak peek of some of the images you will see in a forthcoming photographic pictorial of the ancient site’s stunning remains….

Climate and early human dispersal

PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES—A study finds a link between the strengthening of the Asian summer monsoon and early human migration out of Africa to East Asia during the last interglacial period. The role of climate shifts in shaping early Homo sapiens dispersal to East Asia is an important aspect of human history.  However, the subject remains underexplored due to a lack of coordinated paleoclimate and paleoanthropological data. Hong Ao, Jiaoyang Ruan, and colleagues combined records of the Asian summer monsoon from the Chinese Loess Plateau with models of East Asian paleoclimate, compilations of paleoanthropological data, and simulations of Homo sapiens habitat suitability. The resulting reconstruction covers the last 280,000 years and connects the orbital-scale influences on Asian summer monsoon dynamics with early human dispersal. The results suggest that the Asian summer monsoon is influenced by Northern Hemisphere ice volume, greenhouse gas concentrations, and summer solar radiation. The monsoon strengthened between 125,000 and 70,000 years ago, increasing temperatures and precipitation across Asia. The monsoon strengthening coincides with the earliest fossil H. sapiens specimens at multiple locations in Asia. According to the authors, the strengthening of the Asian summer monsoon, along with a coincident deterioration of the climate in Southeast Africa, may have spurred the dispersal of early humans from Africa into East Asia.

Cult mentality: SLU professor makes monumental discovery in Italy

SAINT LOUIS UNIVERSITY—Douglas Boin, Ph.D., a professor of history at Saint Louis University, made a major announcement at the annual meeting of the Archeological Institute of America, revealing he and his team discovered an ancient Roman temple that adds significant insights into the social change from pagan gods to Christianity within the Roman Empire. 

Researchers rely on the earth’s magnetic field to verify an event mentioned in the Old Testament

TEL-AVIV UNIVERSITY—A breakthrough achieved by researchers from four Israeli universities – Tel Aviv University, The Hebrew University of Jerusalem, Bar-Ilan University and Ariel University– will enable archaeologists to identify burnt materials discovered in excavations and estimate their firing temperatures. Applying their method to findings from ancient Gath (Tell es-Safi in central Israel), the researchers validated the Biblical account: “About this time Hazael King of Aram went up and attacked Gath and captured it. Then he turned to attack Jerusalem” (2 Kings 12, 18). They explain that unlike previous methods, the new technique can determine whether a certain item (such as a mud brick) underwent a firing event even at relatively low temperatures, from 200°C and up. This information can be crucial for correctly interpreting the findings. 

The multidisciplinary study* was led by Dr. Yoav Vaknin from the Sonia & Marco Nadler Institute of Archaeology, Entin Faculty of Humanities, at Tel Aviv University, and the Palaeomagnetic Laboratory at The Hebrew University. Other contributors included: Prof. Ron Shaar from the Institute of Earth Sciences at The Hebrew University, Prof. Erez Ben-Yosef and Prof. Oded Lipschits from the Sonia & Marco Nadler Institute of Archaeology at Tel Aviv University, Prof. Aren Maeir from the Martin (Szusz) Department of Land of Israel Studies and Archaeology at Bar-Ilan University and Dr. Adi Eliyahu Behar from the Department of Land of Israel Studies and Archaeology and the Department of Chemical Sciences at Ariel University. The paper has been published in the scientific journal PLOS ONE.

Prof. Lipschits: “Throughout the Bronze and Iron Ages the main building material in most parts of the Land of Israel was mud bricks. This cheap and readily available material was used to build walls in most buildings, sometimes on top of stone foundations. That’s why it’s so important to understand the technology used in making these bricks.”

Dr. Vaknin adds: “During the same era dwellers of other lands, such as Mesopotamia where stone was hard to come by, would fire mud bricks in kilns to increase their strength and durability. This technique is mentioned in the story of the Tower of Babel in the Book of Genesis: “They said one to another, Come, let us make bricks and fire them thoroughly. So they used brick for stone”(Genesis 11, 3). Most researchers, however, believe that this technology did not reach the Land of Israel until much later, with the Roman conquest. Until that time the inhabitants used sun-dried mud bricks. Thus, when bricks are found in an archaeological excavation, several questions must be asked: First, have the bricks been fired, and if so, were they fired in a kiln prior to construction or in situ, in a destructive conflagration event? Our method can provide conclusive answers.”

The new method relies on measuring the magnetic field recorded and ‘locked’ in the brick as it burned and cooled down. Dr. Vaknin: “The clay from which the bricks were made contains millions of ferromagnetic particles – minerals with magnetic properties that behave like so many tiny ‘compasses’ or magnets. In a sun-dried mud brick the orientation of these magnets is almost random, so that they cancel out one another. Therefore, the overall magnetic signal of the brick is weak and not uniform. Heating to 200°C or more, as happens in a fire, releases the magnetic signals of these magnetic particles and, statistically, they tend to align with the earth’s magnetic field at that specific time and place. When the brick cools down, these magnetic signals remain locked in their new position and the brick attains a strong and uniformly oriented magnetic field, which can be measured with a magnetometer. This is a clear indication that the brick has, in fact, been fired.

In the second stage of the procedure, the researchers gradually ‘erase’ the brick’s magnetic field, using a process called thermal demagnetization. This involves heating the brick in a special oven in a palaeomagnetic laboratory that neutralizes the earth’s magnetic field. The heat releases the magnetic signals, which once again arrange themselves randomly, canceling each other out, and the total magnetic signal becomes weak and loses its orientation.

Dr. Vaknin: “We conduct the process gradually. At first, we heat the sample to a temperature of 100°C, which releases the signals of only a small percentage of the magnetic minerals. We then cool it down and measure the remaining magnetic signal. We then repeat the procedure at temperatures of 150°C, 200°C, and so on, proceeding in small steps, up to 700°C. In this way the brick’s magnetic field is gradually erased. The temperature at which the signal of each mineral is ‘unlocked’ is approximately the same as the temperature at which it was initially ‘locked’, and ultimately, the temperature at which the magnetic field is fully erased was reached during the original fire.”

The researchers tested the technique in the laboratory: they fired mud bricks under controlled conditions of temperature and magnetic field, measured each brick’s acquired magnetic field, then gradually erased it. They found that the bricks were completely demagnetized at the temperature at which they had been burned – proving that the method works.    

Dr. Vaknin: “Our approach enables identifying burning which occurred at much lower temperatures than any other method. Most techniques used for identifying burnt bricks are based on actual changes in the minerals, which usually occur at temperatures higher than 500°C – when some minerals are converted into others.”

Dr. Eliyahu Behar: “One of the common methods for identifying mineralogical changes in clay (the main component of mud bricks) due to exposure to high temperatures is based on changes in the absorption of infrared radiation by the various minerals. In this study we used this method as an additional tool to verify the results of the magnetic method.” Dr. Vaknin: “Our method is much more sensitive than others because it targets changes in the intensity and orientation of the magnetic signal, which occur at much lower temperatures. We can begin to detect changes in the magnetic signal at temperatures as low as 100°C, and from 200°C and up the findings are conclusive.”

In addition, the method can determine the orientation in which the bricks cooled down. Dr. Vaknin: “When a brick is fired in a kiln before construction, it records the direction of the earth’s magnetic field at that specific time and place. In Israel this means north and downward. But when builders take bricks from a kiln and build a wall, they lay them in random orientations, thus randomizing the recorded signals. On the other hand, when a wall is burned in-situ, as might happen when it is destroyed by an enemy, the magnetic fields of all bricks are locked in the same orientation.”

After proving the method’s validity, the researchers applied it to a specific archaeological dispute: was a specific brick structure discovered at Tell es-Safi – identified as the Philistine city of Gath, home of Goliath – built of pre-fired bricks or burned on location? The prevalent hypothesis, based on the Old Testament, historical sources, and Carbon-14 dating attributes the destruction of the structure to the devastation of Gath by Hazael, King of Aram Damascus, around 830 BCE. However, a previous paper by researchers including Prof. Maeir, head of the Tell es-Safi excavations, proposed that the building had not burned down, but rather collapsed over decades, and that the fired bricks found in the structure had been fired in a kiln prior to construction. If this hypothesis were correct, this would be the earliest instance of brick-firing technology discovered in the Land of Israel. 

To settle the dispute, the current research team applied the new method to samples from the wall at Tell es-Safi and the collapsed debris found beside it. The findings were conclusive: the magnetic fields of all bricks and collapsed debris displayed the same orientation – north and downwards. Dr. Vaknin: “Our findings signify that the bricks burned and cooled down in-situ, right where they were found, namely in a conflagration in the structure itself, which collapsed within a few hours. Had the bricks been fired in a kiln and then laid in the wall, their magnetic orientations would have been random. Moreover, had the structure collapsed over time, not in a single fire event, the collapsed debris would have displayed random magnetic orientations. We believe that the main reason for our colleagues’ mistaken interpretation was their inability to identify burning at temperatures below 500°C. Since heat rises, materials at the bottom of the building burned at relatively low temperatures, below 400°C, and consequently the former study did not identify them as burnt – leading to the conclusion that the building had not been destroyed by fire. At the same time, bricks in upper parts of the wall, where temperatures were much higher, underwent mineralogical changes and were therefore identified as burnt – leading the researchers to conclude that they had been fired in a kiln prior to construction. Our method allowed us to determine that all bricks in both the wall and debris had burned during the conflagration: those at the bottom burned at relatively low temperatures, and those that were found in higher layers or had fallen from the top –at temperatures higher than 600°C.”

Prof. Maeir: “Our findings are very important for deciphering the intensity of the fire and scope of destruction at Gath, the largest and most powerful city in the Land of Israel at the time, as well as understanding the building methods prevailing in that era. It’s important to review conclusions from previous studies, and sometimes even refute former interpretations, even if they came from your own school.” Prof. Ben-Yosef adds: “Beyond their historical and archaeological significance, ancient building methods also had substantial ecological implications. The brick firing technology requires vast quantities of combustive materials, and in ancient times this might have led to vast deforestation and even loss of tree species in the area. For example, certain species of trees and shrubs exploited by the ancient copper industry in the Timna Valley have not recovered to this day and the industry itself ultimately collapsed once it had used up its natural fuels. Our findings indicate that the brick firing technology was probably not practiced in the Land of Israel in the times of the Kings of Judah and Israel.”

Unraveling the mysteries of the Mongolian Arc: exploring a monumental 405-kilometer wall system in Eastern Mongolia

HEBREW UNIVERSITY OF JERUSALEM— Prof. Gideon Shelach-Lavi from Hebrew University and Prof. Amartuvshin Chunag from the National University of Mongolia, and their team unveil a new discovery in their latest research published in the Journal of Field Archaeology. Their paper, “Unraveling the Mongolian Arc: a Field Survey and Spatial Investigation of a Previously Unexplored Wall System in Eastern Mongolia,” sheds light on a monumental wall system that has remained largely overlooked in existing academic discourse.

The “Mongolian Arc,” spanning 405 kilometers in eastern Mongolia, comprises an earthen wall, a trench, and 34 accompanying structures. Constructed between the 11th and 13th centuries A.D., this intricate system has emerged as a pivotal yet understudied facet of historical architectural marvels.

The research, conducted through a collaborative effort, involved a comprehensive approach combining remote sensing data collection, archaeological field surveys, and analysis through geographic information systems (GIS). Professors Shelach-Lavi and Amartuvshin’s team also delved into ancient written sources to offer a preliminary interpretation of the design and potential functions of the Mongolian Arc.

“Understanding the significance of the Mongolian Arc unlocks profound insights into medieval wall systems, raising pertinent questions about the motives, functionality, and enduring consequences of such colossal constructions,” remarked Prof. Gideon Shelach-Lavi.

This study is part of a larger multidisciplinary project, funded by a generous research fund from the European Research Council (ERC) addressing the construction of extensive walls and structures in northern China and eastern Mongolia during the 11th–13th centuries A.D. The findings not only contribute to unraveling historical mysteries but also offer a framework for exploring the broader socio-political, economic, and environmental impacts of such endeavors.

The published paper marks a pivotal milestone in the ongoing investigation, sparking renewed interest and further inquiry into ancient architectural wonders and their societal implications.

The Grandeur of it All: A Pictorial

If you have not personally visited the iconic Acropolis in Athens, Greece, you may have a mind’s-eye image of what it might be like to walk about its space, perched high in central Athens with breathtaking views of the city below and around the “rock”, as it is often called. Most of us have only experienced it remotely through books, magazines and on the internet.

But nothing can compare to an up-close-and-personal visit. Slowly scaling the verticality of my managed approach to the summit, I became surprised and  overwhelmed by how massive the ancient structural remains actually were, compared to the image I had harbored so long in my mind. 

Here, for anyone’s enjoyment, are a few photographic images of the great Acropolis experience. 

But may I offer a bit of my own advice….take the time and resources to see it for yourself, as nothing can substitute for actually being there. You will be amazed at the ‘bigness’ of it all. 

See the website to get your journey started.
