Did Ancient People Use the Baghdad Battery to Harness Electricity?
The artefact commonly known as the "Baghdad Battery" — more precisely, the Khujut Rabu jar — is a ceramic vessel containing a copper cylinder and an iron rod, discovered in a Parthian-period context near Baghdad, Iraq, in the 1930s. When Wilhelm König, then director of the National Museum of Iraq, first described the assemblage in 1938, he proposed that the components could function as a galvanic cell: an electrochemical device capable of generating a small electric current when filled with an acidic electrolyte. This hypothesis has persisted in popular and some scholarly discourse for nearly nine decades, making the Baghdad Battery one of the most frequently cited examples of alleged ancient technology that anticipates modern scientific knowledge.
