Iron in Egyptian relics came from space
Meteorite impacts thousands of years ago may have helped
to inspire ancient religion.

The 5,000-year-old iron bead might not look like much,
but it hides a spectacular past: researchers have found
that an ancient Egyptian trinket is made from a
meteorite.
The result, published on 20 May in Meteoritics &
Planetary Science1, explains how ancient Egyptians
obtained iron millennia before the earliest evidence of
iron smelting in the region, solving an enduring mystery.
It also hints that they regarded meteorites highly as
they began to develop their religion.
“The sky was very important to the ancient Egyptians,”
says Joyce Tyldesley, an Egyptologist at the University
of Manchester, UK, and a co-author of the paper.
“Something that falls from the sky is going to be
considered as a gift from the gods.”
The tube-shaped bead is one of nine found in 1911 in a
cemetery at Gerzeh, around 70 kilometres south of Cairo.
The cache dates from about 3,300 bc, making the beads the
oldest known iron artefacts from Egypt.
A study in 1928 found that the iron in the beads had a
high nickel content — a signature of iron meteorites —
and led to the suggestion that it was of celestial
origin2. But scholars argued in the 1980s that accidental
early smelting could have led to nickel-enriched iron3,
and a more recent analysis of oxidized material on the
surface of the beads showed low nickel content4.
