Babylonian Batteries

These 20 batteries were created by a Babylonian scientist after they visited Baghdad. The 20 batteries create around 20 volts each, a total of a 400 volts.

Origin
The Baghdad Battery, sometimes referred to as the Parthian Battery, is the common name for a number of artifacts created in Mesopotamia, during the dynasties of Parthian or Sassanid or Persian Empire period (the early centuries AD), and probably discovered in 1936 in the village of Khuyut Rabbou'a, near Baghdad, Iraq. These artifacts came to wider attention in 1938 when Wilhelm König, the German director of the National Museum of Iraq, found the objects in the museum's collections. In 1940, König published a paper speculating that they may have been galvanic cells, perhaps used for electroplating gold onto silver objects. Though far from settled, this interpretation continues to be considered as at least a hypothetical possibility.[4] If correct, the artifacts would predate Alessandro Volta's 1800 invention of the electrochemical cell by more than a millennium.
