4,000 yo copper weapons found in Uttar Pradesh

A farmer was levelling his field when he found a large number of copper swords and harpoons. He took all of them as he thought they were made of gold or silver. However, locals informed cops and the Archaeological Survey of India (ASI) swung into action. The weapons can be traced to the copper age. "These copper hoards belong to the Chalcolithic period (copper age) and the presence of Ochre Coloured Pottery is directly associated with this time." The Chalcolithic period is generally dated between 2,000 and 1,500 BCE.
