  • Ancient Metallurgy - University of California, San Diego

    Iron appeared in Africa by 600 BC, probably from Southwest Asia via Egypt, Nubia, and the Sahel corridor running south of the Sahara, and substantial iron working began in what is today Nigeria by the 300s. In most parts of the world, the use of iron largely displaced the prior use of bronze, and hence the "Iron Age" succeeded the "Bronze Age."
