Nok and the Early Iron Age
The Nok culture of central Nigeria (about 1500 BCE to about 1 CE), its terracotta sculpture, early iron smelting and the debate over its origin, farming and settlement, Bernard Fagg and the 1943 discovery, looting and the art market, and later early sites (Igbo-Ukwu, Jenne-jeno).
Terracotta and iron
Nok shows that complex societies with skilled artists and iron technology existed in central Nigeria more than two thousand years ago. Jenne-jeno on the inland Niger delta in Mali (from about 250 BCE) shows early urbanism without a single ruler's palace, challenging the idea that cities need kings.
