Battery, ca. 2500 BC

The Baghdad Battery is a ceramic pot containing a copper tube with an iron rod inside. Replicas of this battery are indeed capable of creating some voltage. Perhaps the Ancient Babylonians knew the method of galvanization for which these containers were used, although skeptics argue that they only served to store scrolls.
