These indigenous people were not the first to use meteorites as a source
of iron. Early man’s experience with the smelting and melting of other
metals did not help in producing iron; it first came into use about
1,000 years later than bronze. But the ancients did know that iron
existed. It was regarded as extremely rare and precious because it fell
from the sky in exceedingly small quantities. |

In old Sumeria, iron was called “Sky Metal” and the pharaohs in ancient
Egypt knew it as “black copper from the sky”. King Tut (Tutankhamun) was
buried with a little iron dagger made from meteorite iron right on his
breast; obviously it was his most precious possession. |

Legends also exist that Excalibur was made of metal found as an iron
meteor and that the armor and weapons of the ancient Greek hero Achilles
were similarly composed. These would consequently contain a lot of
nickel, and would accidentally produce “steel”. Interestingly, there are
such weapons in the world. The Indonesian Keris (Kris Knife) is
traditionally made from meteor steel. |

The Gibeon Meteorite shower is the most extensive meteorite shower known
on Earth and covers a large elliptical area of some 275 by 100
kilometers. Most fragments fell just southeast of Gibeon in Great Nama
Land, Namibia. To date, some 120 specimens with a weight of almost 25
tons have been recorded. In addition, an unknown number have been
collected but never recorded. |

The Gibeon Meteorite was first reported by Capt. J.E. Alexander in 1838.
He heard of masses of native iron up to two feet square on the east side
of the Great Fish River. He sent some materials to the chemist John
Herschel in London, who established their meteoritic origin. |

In the years following, Europeans established large cattle ranches in
the area and recovered many more large meteorites. The first large piece
weighing 81 kg was carried by ox-wagon for 800 miles to Cape Town by
John Gibbs in 1853. A 232 kg mass was recovered in 1857. Many masses
between 100 and 500 kg were recovered in the years shortly after 1900.
These specimens are displayed in the Post Street Mall and at the museum
of the Geological Survey of Namibia in Windhoek (Namibia’s Capital) and
a number of them have also been donated to various museums around the
world. |
