The significant finding raises the possibility that the indian subcontinent is where the method of mining, smelting, forging, and shaping iron originated, according to a BBC article.
Namanu was gathered by archaeologists from the tamil Nadu sites of Adichanallur, Sivagala, Mayiladumparai, Kilnamandi, Mangadu, and Thellunganun.
The finding calls into question the long-held belief in archeological circles that the iron Age started in the Hittite Empire of Anatolia, where iron usage and smelting are thought to have first appeared about 1300 BC. The tamil Nadu discovery, however, casts doubt on this idea and raises the possibility that the iron Age started at least a millennium earlier than previously thought by archaeologists.
According to scientists, the mass manufacturing of iron that began during the iron Age thousands of years ago was caused by the smelting of iron ore.
