The earliest evidence of metalworking dates back to about 4,000 b.C. in Mesopotamia.
Vulcan was the Roman god of the forge and this shows how important metalworking was for them.
The art of forging flourished in the Middle Ages due to constant wars and to the need for more and more efficient weapons.
The discovery of water power to drive mechanical hammers and then the invention of the steam engine led to the beginning of modern forging.
Electricity made ancient forge techniques obsolete
