Study establishes revised radiocarbon dating of the Kyrenia shipwreck

Published

on

A new study, published in the open-access journal PLOS ONE, has applied new radiocarbon calibration techniques to date the Kyrenia shipwreck.

The Kyrenia is an ancient Greek merchant ship discovered off the coast of Cyprus in 1965. The wreck was found preserved with more than half its hull timbers intact, providing a unique insight into ancient Greek shipbuilding during antiquity.

Underwater excavations uncovered 391 amphorae at the wreck site, containing cargo such as wine, olive oil, and almonds. Archaeological evidence suggests that the ship’s final voyage took place around 300 BC. However, this date does not align with radiocarbon dating of samples taken from the wreck site.

According to the study authors, this discrepancy is due to outdated radiocarbon calibration data that can be distorted due to variations in atmospheric carbon over time. As radiocarbon dating techniques have improved, some time periods within the current Northern Hemisphere calibration curve have yet to be updated.

In this new study, the researchers applied new samples and modern dating techniques to revise the calibration date. This has revealed a new date of the ship’s last voyage to 280 BC, corresponding to around the same period that the archaeological evidence indicates.

“We are excited to apply scientific techniques to date the famous Kyrenia Ship a little over 2300 years ago. Central to the history of ship technology and maritime trade in the classical Mediterranean, the methods we use to date the ship – and solutions to various technical challenges we had to overcome – will now help date other shipwrecks and better inform the history of ancient seafaring,” said the study authors.

The authors also applied the new radiocarbon calibration curve to radiocarbon dates from another Greek ship, the Mazotos ship, and estimated an age around 370 BC for the last voyage, again slightly later than indicated by previous research.

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.
