Archaeologists investigate the mysterious Mongolian Arc

Published

on

A new study by The Hebrew University of Jerusalem, working in collaboration with the National University of Mongolia, has revealed new insights regarding the Mongolian Arc, a 405 km long wall system located in Eastern Mongolia.

The Mongolian Arc consists of an earthen wall, a trench, and numerous structures, which is part of a much larger system of walls in Mongolia and China built between the 11th and 13th centuries AD.

The study, published in the Journal of Field Archaeology, involved a comprehensive approach combining remote sensing data collection, archaeological field surveys, and analysis through geographic information systems (GIS).

This enabled the study authors to create the first precise mapping of the complete scope of the Mongolian Arc, encompassing details of its orientation and variations in width. In addition, they were able to trace the complete wall line and identify 34 structures associated with it.

“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,” said Prof. Gideon Shelach-Lavi.

Upon comparing the Mongol Arc with another wall section to the north, the team observed that the Arc exhibits structures in closer proximity to each other, averaging around 8 kilometres apart, whereas the other wall’s structures are situated at distances ranging from 20 to 30 kilometres.

Also, another major difference between the Arc and the north section of wall is the large gaps found in the Arc that range between 3 and 8 km’s, with some around 15 km’s.

Through the examination of historical documents from the official records of the Liao and Jin dynasties, it has been suggested that the Mongal Arc segment was hurriedly constructed in AD 1200 to serve a defensive measure against imminent Mongol invasions.

However, the lack of visibility and communication between each structure contradicts the Arc effectively serving a military function. Instead, the study hypothesises that the Arc was built to regulate the movement of both people and livestock, while also serving an administrative function for tax collection.

The study authors said: “We are currently making plans for the next stage of field research, which will build upon the results reported here and aims to test some of our hypotheses. During the upcoming field season, our objectives include conducting test excavations at two of the structures and the wall line itself. Through these excavations, we hope to gain a better understanding of their features and structures, determine the construction dates and duration of use, and shed light on the activities of the people.”

Archaeologists study submerged Nabataean temple

Published

By

In 2023, archaeologists discovered the submerged remains of a Nabataean temple during an underwater survey of the ancient port of Puteoli, located in modern-day Pozzuoli, Italy.

Puteoli was established in the mid-6th century BC as a Greek colony called Dicaearchia. After the Roman conquest of Campania following the First Samnite War, Dicaearchia was annexed into the Roman Republic, which later founded the colony of Puteoli.

Puteoli served as one of the primary trading hubs for Rome, emerging as the great emporium of foreign trade for the Alexandrian grain ships and goods from across the Roman world.

Due to the position of Puteoli in the Phlegraean Fields, an active volcanic region, volcanic bradyseismic activity has raised and lowered the geology on the peninsula, resulting in parts of Puteoli being submerged.

The results of a year-long study, published in the journal Antiquity, has mapped and reconstructed parts of the submerged temple, the only known temple located outside of Nabataea – an allied kingdom of Rome that controlled territory from the Euphrates to the Red Sea.

Using a photogrammetric survey, the researchers have identified that the temple had a rectangular plan and two rooms with access facing north, linked to the internal routes of the vicus Lartidianus (an area designated for foreign people engaged in trade).

Within one of the rooms (designated Room A) are two altars made of white Luni marble, and a mensa with eight rectangular recesses for housing aniconic betils. In the second room (designated Room B), the southern perimeter wall has a white marble slab covering, one of which shows the inscription Dusari sacrum, meaning “consecrated to Dushara”, the chief deity of the Nabataean pantheon.

According to the study authors: “The existence of a Nabataean sanctuary within the port area confirms that there was a community from that region participating in the commercial activities of Puteoli.”

“The integration of these individuals within the local community is evident in the building techniques and materials used in the construction of the temple, and for the choice of Latin for the inscriptions to their supreme god, the lord of the mountains and the germinating force of nature, Dushara.”

Treasure hoard discovered in Viking farmstead

Published

Archaeologists from the Archaeological Museum at the University of Stavanger have discovered a Viking treasure hoard in the Hjelmeland municipality, Norway.

Excavations were in preparation for the construction of a new farm track to identify any archaeological remains in situ. The researchers discovered traces of a Viking farmstead, consisting of several structures for both the inhabitants and their animals.

Numerous domestic and agricultural objects have been unearthed, including soapstone pots, knife blades, rivets, and whetstones used for sharpening tools.

Mari Krogstad Samuelsen and Ola Tengesdal Lygre were excavating a dwelling used for housing slaves, when they identified what appeared to be twisted hedging wire at a depth of 20 centimetres.

Upon further inspection, the objects were revealed to be four heavy silver bracelets, each adorned with distinct decorative elements.

“This is definitely the biggest thing I have experienced in my career”, says archaeologist and project manager Volker Demuth from the Archaeological Museum at the University of Stavanger.

“This is a unique find, because we very rarely find such objects exactly where they were placed. As a rule, such valuable objects are discovered on fields that have been ploughed, where an object has been completely removed from its original context,” added Demuth.

According to the archaeologists, the hoard dates from around the 9th century AD and shares similarities to silver necklaces found in Hjelmeland in 1769. At that time, there were no silver mines operating in Norway, so all the silver used by the Vikings was sourced from abroad, obtained through trade, received as gifts, or taken as loot during their raiding expeditions.

Evidence of burning also indicates that the farmstead was destroyed by fire, likely during a time of conflict that required the necessity for the inhabitant’s valuables to be deposited in the ground for security.
