Ceramic jars with copper cylinders and iron rods from the Khujut Rabu area near Baghdad entered popular literature as possible galvanic cells after Wilhelm König’s battery hypothesis. Experimental reconstructions can produce small voltages; that does not prove ancient electrical intention. Many archaeologists read the assemblages as scroll or papyrus containers. Originals are reported lost in the 2003 Iraq Museum looting — another custody fact for the margin.
Replica voltage ≠ intention
Status disputed on the electrical interpretation; the objects’ existence in the scholarly literature is not in doubt. No History.com photos hosted here.
