Gold
People have been using gold to make jewelry since the Stone Age. You can find it just lying in little lumps in streams here and there. And gold is always pretty and yellow, even when it is just lying in the stream. But to get more gold you have to find gold mines underground.
One early source of gold was Ethiopia. The Egyptians
got their gold by trading for it with the Nubians
in Ethiopia, as well as from their own mines. Many places in Africa
have gold mines where people mined gold for jewelry
and decorations. In West Africa,
people traded gold for salt from the
Sahara desert to their
north.
And there were also gold mines in Rumania.
That's one reason why the Romans
conquered it. The Romans made gold coins
out of this gold.
Gold is easy to work, but it is not strong enough to
make tools or weapons out of. For that you need bronze
or iron.
