Evidence of steel tools being used in Europe during Late Bronze Age

Published

Researchers have discovered that steel tools were being used on the Iberian Peninsula during the Late Bronze Age 2,900 years ago.

An international study has conducted a geochemical analysis on stone pillar stelae found in the Iberian Peninsula, revealing that engravings on the rock face were created using tempered steel.

This is supported by a metallographic analysis of an iron chisel from the same period found at Rocha do Vigio, which has the necessary carbon content to be classified as steel.

Until recently, it was assumed that the inhabitants of the region lacked the skill and understanding to produce steel in the Early Iron Age, and certainly not in the Late Bronze Age, which only became widespread through contact and conquest by the Romans. The Iberian Bronze Age started around 1800 BC, concluding with the Iberian Iron Age sometime during the 9th century BC.

Dr. Ralph Araque Gonzalez, an archaeologist from the University of Freiburg, said: “The chisel from Rocha do Vigio and the context where it was found, shows that iron metallurgy, which includes the production and tempering of steel, were probably indigenous developments of decentralised small communities in Iberia, and not due to the influence of later colonisation processes.”

The results of the study, published in the Journal of Archaeological Science, conducted an analysis of stelae pillars made from silicate quartz sandstone. “Just like quartzite, this is an extremely hard rock that cannot be worked with bronze or stone tools, but only with tempered steel,” says Gonzalez.

A closer inspection of the chisel from Rocha do Vigio, reveals that it consists of heterogeneous yet astonishingly carbon-rich steel. To confirm their findings, the researchers carried out an experiment involving a professional stonemason, a blacksmith and a bronze caster, and attempted to work examples of silicate quartz sandstone using chisels of different materials.

The stonemason was unable to work the stone with either the stone or the bronze chisels, or even using an iron chisel with an untempered point. “The people of the Late Bronze Age in Iberia were capable of tempering steel. Otherwise, they would not have been able to work the pillars,” concludes Araque Gonzalez as a result of the experiment.

Archaeologists link biblical event to findings in the City of David

Published

Excavations led by the Israel Antiquities Authority, working in collaboration with Tel Aviv University and the Weizmann Institute of Science, have linked an event mentioned in the Bible to archaeological findings from the City of David.

The results of the excavation, published in the journal PNAS, challenges the accepted perceptions of the development of Jerusalem during the rule of the kings of Judah. In particular, the scope of Jerusalem during the reigns of David and Solomon and the period that followed.

The researchers have accurately dated several structures, including the city walls and royal construction projects, which are linked to Jerusalem’s growth to the west during the period of King Hezekiah around 2,700-years-ago.

The previous assumption was that the city expanded due to the arrival of refugees due to the Assyrian exile, however, the new findings now indicate that the city spread towards Mount Zion in the 9th century BC during the reign of King Jehoash, 100 years before the Assyrian exile period.

Prof. Yuval Gadot from the Department of Archeology at Tel Aviv University, said: “In light of this, the new research teaches us that the expansion of Jerusalem is a result of internal-Judean demographic growth and the establishment of political and economic systems.”

Excavations have also revealed that the wall of Jerusalem on the eastern slopes of the city of David is older than previously thought. It was thought that the wall in this area was built by Hezekiah, King of Judah, however, findings now indicate that it dates from the reign of King Uzziah.

King Uzziah is described in a passage in the bible that reads: “’And Uzziah built towers in Jerusalem… and strengthened them” (2 Chronicles 26:9).

According to Dr. Uziel: “Until now, many researchers have assumed that the wall was built by Hezekiah during his rebellion against Sennacherib (King of Assyria), in order to defend Jerusalem during the Assyrian siege. It is now apparent that the wall in the easter part of the City of David, was built earlier and as part of the construction of the city during the reign of King Uzziah.”

Ancient Pueblo used conch-shell trumpets for communication

Published

A new study, published in the journal Antiquity, suggests that the ancient Pueblo culture used conch-shell trumpets for communication.

The focus of the study is the site of the Chaco Canyon in north-west New Mexico. Located in Chaco Culture National Historic Park, Chaco Canyon contains numerous small dwellings and multi-story buildings known as great houses.

Based on the density of structures, archaeologists speculate that the site was once a bustling metropolis, inhabited by as many as 2,300 people during its height from AD 1050 to 1130.

Conch-shell trumpets have been found in burial contexts at Chaco Canyon, which today are used in contemporary Pueblo ritual practices.

Using a Soundshed Analysis model, archaeologists have digitally modelled the sound of a conch-shell trumpet being sounded at a great house in relation to other features in the landscape. Soundshed Analysis calculates the distance a sound can travel from a point, taking into account both the type of sound and environmental conditions such as elevation and ambient noise.

“Chaco Canyon is surrounded by over one hundred understudied great house communities”, says lead author Professor Ruth Van Dyke from Binghamton University. “We sought to determine if extra-canyon great house communities demonstrated relationships similar to Chaco Canyon between landscape, community layout, and sound.”

In this case, the team modelled the sound of a conch from great houses at five Chacoan communities to determine whether it would reach all habitation sites within the community.

They found that if somebody blew a conch-shell trumpet from the great house at the centre of all five Chacoan communities, the sound would have reached almost all of the surrounding settlements.

This suggests that ancient Puebloans may have managed their land-use and community structures around the sound of trumpets. The sound was potentially used to signal communal activities, such as religious ceremonies.

“This is not unlike the idea of a medieval church bell calling a community to mass”, states Professor Van Dyke.

It also indicates how Chacoan heritage sites should be managed going forward.

“Soundscapes were meaningful dimensions of past experiences, landscapes, and environments and are important facets of social interaction in the ancient world,” observes Professor Van Dyke. “Management of archaeological and heritage sites should incorporate consideration of the auditory environment.”
