The Baghdad Battery interpretation

Record summary

The so-called Baghdad Battery refers to ceramic vessels with copper cylinders and iron rods excavated near Baghdad and often assigned to the Parthian or early Sasanian period. Wilhelm König proposed that they might have generated an electrochemical current, leading to claims of ancient electrical technology. Replicas can produce small voltages under particular conditions, but no direct evidence shows that the vessels were designed or used as batteries. Alternative interpretations include storage containers, ritual objects, or laboratory-related equipment, and their original context is poorly documented.
