Ancient Egyptian bead ‘from meteorite’, say researchers

Analysis of an iron bead has proved ancient Egyptians created jewellery from meteorites, experts have said.

Researchers at the Open University and University of Manchester have made the claim following analysis of the bead, which dates from 3,350 to 3,600BC.

 

Previously, it had been claimed the 2cm bead was a product of smelting.

 

However, researchers found the bead had a “nickel-rich chemical composition [which] confirms its meteorite origins”, a Manchester spokesman said.

The bead, which was excavated from a burial site south of Cairo in 1911, dates from around 2,500 years before the Iron Age and predates the rise of the Pharaohs by around 400 years>
The spokesman said the jewellery, known as the Gerzeh bead after the name of the site, was the “earliest discovered use of iron by the Egyptians”.

‘Unique fingerprint’

The bead forms part of Manchester Museum’s Egyptology collection and was loaned to the University of Manchester and Open University for analysis.

It was suggested in a study in the 1920s that it may have come from a meteorite, but that was rejected by experts in the 1980s who said accidental early smelting could also have been the origin of the mix of iron and nickel.
Scholars from Manchester and the Open University used a combination of an electron microscope and an X-ray scanner to prove the mix of the metals could only have come from a meteorite, the spokesman said.
The University of Manchester’s Professor Philip Withers said the composition was identifiable as “meteorites have a unique micro-structural and chemical fingerprint because they cooled incredibly slowly as they travelled through space”.
He added that it was “really interesting to find that fingerprint turn up in Egyptian artefacts”.
Dr Joyce Tyldesley, a senior lecturer in Egyptology, said meteorite iron would have had profound significance for the ancient Egyptians.

“Today, we see iron first and foremost as a practical, rather dull metal [but] to the ancient Egyptians, it was a rare and beautiful material which, as it fell from the sky, surely had some magical or religious properties,” she said.

“They therefore used this remarkable metal to create small objects of beauty and religious significance which were so important to them that they chose to include them in their graves.”
