High-Tech Tools Map Baptistery of St. John

SAN DIEGO, CALIFORNIA—Using Lidar technology, ultra-high-resolution photography, and thermal imaging techniques, Mike Hess and Mike Yeager of the University of California, San Diego, created a 3-D digital model of the interior, exterior, and façade of the Baptistery of St. John, which sits in Florence’s Piazza del Duomo. “The point cloud data—taken from 80 Lidar scans—becomes the geometric scaffold for the high-resolution thermal imagery. The data can be projected into 3-D space so we know exactly what we’re looking at spatially. The drawings are spatially accurate and we can now pull a measurement for any part of the building we want to look at, down to the millimeter,” Yeager said in a University of California, San Diego press release. The construction of the Baptistery was completed in 1128 on the site of a Roman temple dating to the fourth or fifth century A.D. Yeager and Hess were joined by cultural heritage engineer Maurizio Seracini, Gianfranco Morelli of Geostudi Astier, and Vid Petrovic of IGERT-TEECH to examine an unexcavated area of the ancient site beneath the Baptistery with ground-penetrating radar. The team found what could be a staircase, two vaulted rooms, and a series of walls and hallways. “Now we’re able to use this technology to reference that data in space and ‘fly’ from the domed ceiling of the Baptistery down into the dirt to the ancient rooms beyond,” Yeager said.

A History of Pollution

PITTSBURGH, PENNSYLVANIA—Geologists led by Aubrey L. Hillman of the University of Pittsburgh used sediment cores from Erhai Lake to examine levels of heavy metal pollution in southwestern China over the past 4,500 years. According to a report in Science, they found a rise in copper contaminants at the start of China’s Bronze Age, but those levels remained stable until the Mongols conquered China in the late thirteenth century A.D. The sediment cores show that heavy metal pollution during the reign of Kublai Khan and the Mongols, who mined and processed silver for coins, jewelry, art, and taxes, was three to four times higher than modern industrialized mining.

4,000-Year-Old Barrow Yields Intact Burials

KRAKOW, POLAND—A Bronze-Age burial mound found in a forest in southeastern Poland through the use of Lidar technology has yielded five burials and a World War I firing post. “Importantly, the mound is the first known structure of this type in the Lublin Upland, as well as throughout [southern Poland], probably dating back to the turn of the third and second millennium B.C.,” Piotr Wlodarczak of the Polish Academy of Sciences told Science & Scholarship in Poland. Four graves of the Strzyżów culture were excavated. “The burial rite is slightly different than in the earlier period, the late Neolithic. The mound we examined had not been raised a single grave of a chosen person, but a few graves,” he added. The largest grave had been placed in the center of the mound. All of them contained hundreds of beads made from clam shells, copper jewelry, animal fang pendants, and flint tools. Rifle shells, shrapnel, and an iron fitting from an ammunition basket suggest that the top of the mound had been used as a firing post during the First World War.

Room Discovered at Bronze Age Temple in Sidon

SIDON, LEBANON—An underground room of the Temple of Sidon has been discovered by a team from the British Museum and the Directorate General of Antiquities of Lebanon at the Frères archaeological site. “Sealed by the imposition of a Persian period building constructed on top of it, this new room is of the highest importance in terms of its monumentality and untouched pottery material, both [domestically produced] and imported from Cyprus and Mycenae,” read a statement from the delegation that was reported in The Daily Star. Wooden artifacts, pottery, and utensils were found within the room, built with monumental stones. The site will be preserved in situ, next to the new national archaeology museum now under construction. For more on archaeology in Lebanon, see "Rebuilding Beirut."

Islamic Coins Discovered in Viking’s Shield Boss

TRONDHEIM, NORWAY—Last year, a metal detectorist discovered a sword from the Viking Age in a field in central Norway. Archaeologists from the Museum of Natural History and Archaeology at the Norwegian University of Science and Technology excavated the site, and found a grave dating to about A.D. 950 that contained the remains of a Viking and his shield, in addition to the inscribed, high-quality sword. Hidden inside the shield boss they found a leather purse that contained several Islamic coins. Norwegian Vikings arrived in Spain in the 800s, where they may have come in contact with Islamic culture, or perhaps the coins were obtained through trade. “We have not managed to find out who owned the sword, but we know that he was a well-traveled man,” archaeologist Ingrid Ystgaard told NRK, as reported by ThorNews. The shield boss also bears combat scars. “The shield boss has a clear cut mark by an ax or a sword. If he died in combat, we do not know,” added Ystgaard.

Stone Tools Suggest Modern Humans Lingered in Arabia

WASHINGTON, D.C.—A study of stone tools from Arabia, northeastern Africa, and the Middle East by Jeffrey Rose of the Ronin Institute, and Anthony Marks of Southern Methodist University, begins with the evolution of stone tools from the Nile Valley some 150,000 to 130,000 years ago. That was when hunter-gatherers chipped away the edges of a stone core in a systematic way to produce the single, triangular point characteristic of Nubian tools. It had been thought that the modern human makers of these tools moved rapidly to the Levant, where they invented the points, blades, and scrapers known as Emiran tools, first discovered in a cave near the Sea of Galilee in 1951. “The Emiran is the bridge technology. But where did these guys come from?” Rose asked National Geographic News. Rose and Marks propose that some of the early Nile tool-makers first traveled to Arabia, where their descendants spent tens of thousands of years and developed two new toolkits, whose stone points grew smaller and more elongated over time. Rose and Marks add that after climate changed pushed them into the Levant, these modern-human tool makers learned to strike many blades from a single core. The style of their tools may even have been influenced by local toolmakers, possibly Neanderthals. “Archaeologists have always focused so much on ‘out of Africa and into the Middle East’ that we’ve missed an entire chapter of the human expansion in Arabia,” Rose said.

Intact Roman Tombstone Unearthed in England

CIRENCESTER, ENGLAND—A well-preserved Roman tombstone dating between the first and third centuries A.D. has been unearthed in a parking lot in western England, at the site of the Roman town of Corinium. According to Neil Holbrook of Cotswold Archaeology, the inscription on the stone reads: “To the spirit of the departed Bodica [or Bodicaca], wife, lived for 27 years.” Blank space on the piece of carved limestone may have been intended for the use of a spouse or another family member. A skull found near the stone may have belonged to the woman named on the stone. The remains of three children were also uncovered in what may have been a family burial plot. “Perhaps Bodica is a local Gloucestershire girl who’s married an incoming Roman or Gaul from France and has adopted this very Roman way of death,” Holbrook told BBC News.

Examination Shows Pharaoh Senebkay Was Killed in Battle

PHILADELPHIA, PENNSYLVANIA—The Luxor Times reports that an examination of the skeletal remains of Senebkay, discovered in Abydos last year by Josef Wegner and a team from the University of Pennsylvania, recorded 18 injuries to his bones, including vertical cuts to his feet, ankles, and lower back. It is thought that the king, whose family ruled from 1650 to 1600 B.C., died in battle between the ages of 35 and 49. The wounds to his ankles and feet suggest that he was on horseback when he was attacked from below at close range, and then knocked to the ground and killed with ax wounds to his cranium. The researchers also say that he was mummified long after death, suggesting that he was killed far away from home, perhaps in battle with the Hyksos, who occupied Lower Egypt at the time.

Statues of Sekhmet Unearthed at Kom El-Hitan

LUXOR, EGYPT—More than 60 statues of Sekhmet have been found at Amenhotep III’s temple at Kom El-Hitan on Luxor’s west bank. Now Egyptologist Horig Sourouzian has uncovered two more busts of the lioness goddess on the northeastern side of the temple’s pillar halls. One of the statues depicts Sekhmet sitting on a throne; the other, smaller sculpture is of her face. “Some Egyptologists believe that king Amenhotep constructed a large number of statue goddess Sekhmets in an attempt to cure him of a specific disease that he suffered during his reign,” Sourouzian told Ahram Online.

Did Plague Travel From Asia to Europe on the Silk Road?

OSLO, NORWAY—Christian Stenseth of the University of Oslo and his team have examined tree-ring records from Europe and compared that information with more than 7,000 historical outbreaks of the Black Death to see if the weather conditions would have supported large populations of black rats to transmit the bacteria-carrying fleas to humans. “For this, you would need warm summers, with not too much precipitation. Dry but not too dry. And we have looked at the broad spectrum of climatic indices, and there is no relationship between the appearance of plague and the weather,” Stenseth told BBC News. The research team thinks that the wet springs and warm summers in Asia, however, may have caused the great gerbil, which also carries plague, to thrive. “We show that wherever there are good conditions for gerbils and fleas in central Asia, some years later the bacteria shows up in harbor cities in Europe and then spreads across the continent,” he said. Now plague bacteria DNA taken from skeletons across Europe is being analyzed. Large amounts of variation in the genetic material would support the idea of different strains coming from Asia rather than a European rat reservoir.

Cathedral Grave May Have Belonged to a Medieval Knight

HEREFORD, ENGLAND—An osteological study of more than 700 sets of human remains excavated from Hereford Cathedral suggests that one of the graves held the remains of a knight. Analysis of the knight’s teeth shows he was likely from Normandy and had moved to Hereford later in life. The skeleton, which has been dated to between A.D. 1100 and 1300, had several fractures to the ribs and right shoulder that are consistent with injuries sustained while jousting. Only some of the wounds had healed; the unhealed wounds had been sustained close to the time of death. The body also had an unusual twisting break in the lower left leg, perhaps inflicted after a hit to the right side of the upper body while on horseback. The hit could have spun the rider, catching the left foot in the stirrup. “Obviously we can never be sure how people came about their wounds, but in this case there is a considerable amount of evidence suggesting this man was involved in some form of violent activity and the locations of his injuries do match quite closely what might be expected from taking part in mock battles. The fact that he was still doing this after he was 45 suggests he must have been very tough,” Andy Boucher of Headland Archaeology Limited told British Archaeology News Resource.

Defleshed Body Parts Found at Mortuary Complex in Bolivia

LANCASTER, PENNSYLVANIA—In the mortuary complex at Bolivia’s site of Khonkho Wankane, Scott C. Smith of Franklin & Marshall College and Pérez Arias of the University of Pittsburgh unearthed human body parts that may have been defleshed and processed into easy-to-carry pieces. These were “portable ancestors for a mobile population,” Smith told USA Today. In one stone and adobe building, the team discovered nearly 1,000 teeth and small bones that were coated with a thin layer of white plaster, in addition to white-coated pots and tools made of llama bones. White blocks, probably quicklime, were also discovered. Quicklime, which turns to white plaster when exposed to air, is still used to clean skeletons. And an image of a person with defleshed ribs was found carved on a stone pillar outside the mortuary. Researchers think that from the first through fifth centuries A.D. itinerant llama herders used the site to strip flesh and clean the bones of the dead so that they could be carried from place to place. “The dead still played an active and important role in the lives of the living,” Smith explained.To read about another recent discovery made in Bolivia, see "Tiwanaku Drug Paraphernalia Found."
