Copper artefacts reveal new cultural connections
In a recent study by the University of Missouri, researchers have conducted a chemical and isotopic analysis of copper artefacts from southern Africa, revealing new cultural connections between the region’s inhabitants from the 5th to the 20th century.
According to Jay Stephens, a post-doctoral fellow in the MU Research Reactor (MURR) Archaeometry Lab, people residing in South Africa and the Copperbelt region of central Africa were more connected than previously thought.
“Over the past 20 to 30 years, most archaeologists have framed the archaeological record of southern Africa in a global way with a major focus on its connection to imports coming from the Indian Ocean,” he said. “But it’s also important to recognize the interconnected relationships that existed among the many groups of people living in southern Africa. The data shows the interaction between these groups not only involved the movement of goods, but also flows of information and the sharing of technological practices that come with that exchange.”
The origin of rectangular, fishtail, and croisette copper ingots has been a topic of debate among scholars for years. Some argued that they were made only from copper ore extracted from the Copperbelt region, while others suggested they originated from Zimbabwe’s Magondi Belt. Jay Stephens has now revealed that both theories hold true.
“We now have tangible linkages to reconstruct connectivity at various points in time in the archaeological record,” he said. “There is a massive history of interconnectivity found throughout the region in areas now known as the countries of Zambia, Zimbabwe and the Democratic Republic of the Congo. This also includes people from the contemporary Ingombe Ilede, Harare, and Musengezi traditions of northern Zimbabwe between at least the 14th and 18th centuries A.D.”
Researchers analysed small samples taken from 33 copper ingots to arrive at their findings. The samples were carefully selected by the researchers from archaeological collections at the Museum of Human Sciences in Harare, Zimbabwe and the Livingstone Museum in Livingstone, Zambia.
Less than one gram of each of the 33 samples was dissolved with specific acids, leaving behind a liquid mixture of chemical ions. They then conducted an analysis of the samples to determine lead isotopes and other chemical elements.
Stephens said the data they collect is one of the only remaining tangible links that exist today to those precolonial mines in Africa.
“Unfortunately, large open pit mines have destroyed a lot of the archaeological sites and broader cultural landscapes around these geological deposits,” he said. “This makes it a challenge to reconstruct the history related to these mines. It’s a concerning development, especially with the global push toward more electric vehicles which use minerals like copper and cobalt found in the Copperbelt.”

A study of a Roman shipwreck off the coast of Mallorca has identified a new type of amphora.
The shipwreck, known as the shipwreck of Ses Fontanelles, was discovered 65 metres from the coast of a tourist beach near Mallorca’s capital of Palma.
According to a paper published in the journal Archaeological and Anthropological Sciences, the ship dates from the 4th century and likely departed from Cartagena in southeastern Spain while navigating the trade routes of the western Mediterranean.
Archaeologists found in the hold a cargo packaged in amphorae, some of which have painted inscriptions (tituli picti) on the exterior. The inscriptions provide information such as the origin, destination, type of product, and the owner of the goods – identified as “Alunnius et Ausonius.”
The amphorae have been classified into four main group types. The most abundant is the Almagro 51c type amphorae, for which the tituli picti indicate a contents of fish sauce which derives almost exclusively from a single species: the European anchovy (Engraulis encrasicolus)
The other groups consist of the flat-bottomed amphorae, the Keay XIX type, and a new type of amphora named Ses Fontanelles I, which is larger and heavier than most other amphorae types and was used for carrying plant oil.
According to the study authors: “All the analytical data suggest that Alunnius et Ausonius prepared a trade enterprise fleeting, a merchant ship with a cargo composed mainly of fish sauce (Liquaminis flos), in Almagro 51c amphora, oil transported in Ses Fontanelles I amphorae (probably an imitation of Dressel 23 type), and grape derivates or fruits preserved in those substances in flat-bottomed amphorae.”

A new study published in the journal Antiquity has revealed hundreds of previously unrecorded monuments at Baltinglass in County Wicklow, Ireland.
The Baltinglass area (known as ‘Ireland’s Hillfort Capital’) has a high density of Early Neolithic and Late Bronze Age monuments, however, very little evidence has been recorded that dates from the Middle Neolithic period.
According to Dr James O’Driscoll from the University of Aberdeen, the ancient landscape around Baltinglass was incredibly important to the Early Neolithic people, however, the lack of Middle Neolithic evidence suggests that this importance was lost until the Late Bronze Age.
Using advanced LiDAR technology, archaeologists have created detailed three-dimensional models, revealing hundreds of ancient sites that that been destroyed by thousands of years of ploughing.

Light Detection and Ranging (LiDAR), is a method of remote sensing using light in the form of a pulsed laser to measure ranges (variable distances) to the Earth. The differences in the laser return times and wavelengths can be used to compile a 3-D digital map of the landscape.
The most significant discovery from the survey is a cluster of five cursus monuments, the largest example found in both Britain and Ireland. The purpose of such monuments are speculative, but some theories propose that they were used in rituals connected with ancestor veneration, that they follow astronomical alignments, or that they served as buffer zones between ceremonial and occupation landscapes.

According to the study authors: “These five cursus monuments are clearly aligned with burial monuments in the landscape, as well as the rising and setting sun during major solar events such as the solstice.”
“This may have symbolised the ascent of the dead into the heavens and their perceived rebirth, with the cursus physically setting out the final route of the dead, where they left the land of the living and joined the ancestors beyond the visible horizon,” said Dr O’Driscoll.
