The Baghdad battery

One of the most interesting and highly debated artefacts of the Baghdad Museum in Iraq is a clay pot. It is 5-6 inches high and encapsulates a copper cylinder. Suspended in the center of this cylinder—but not touching it—is an iron rod. 

Although it is not known exactly what the use of such a device would have been, the name ‘Baghdad Battery’, or ‘Parthian Battery’, comes from one of the prevailing theories established in 1938 when Wilhelm Konig, the German archaeologist who performed the excavations, examined the battery and concluded that this device was an ancient electric battery.
