The Baghdad Battery, a clay pot with an iron rod and a copper cylinder, may have been the world’s first electric device, dating back to 250 BC. Some researchers believe that the ancient Mesopotamians used it to electroplate gold or silver onto metal objects. Others think that it was a religious artifact, used to create a tingling sensation in the worshipers. #baghdadbattery #electricity #history https://www.imperidox.com/baghdad-battery-ancient-electricity/
