Earliest Battery Known To Man

In 1938 Dr. Wilhelm Konig found several earthenware pots at a dig near
Baghdad, Iraq. The pots dated back 2000 years and were found to be
electrical batteries.
Each pot contained a tube of sheet copper made up of smaller cylinders
soldered to each other with a 60-40 lead-tin alloy. The bottoms of the cylinders
were capped with copper disks and sealed with asphalt or bitumen. Another
layer of asphalt held two suspended iron rods down into the pot and copper
tube and showed evidence of being corroded by acids. When a replica of the
pots was made with freash materials, it was found that the iron rod held at the
top generated between 1.5 and 2 volts of electricity. According to current
historical beliefs, electricity wasn't 'discovered' until AD 1800 in Europe, yet
here it is.
Some researchers have said we only know about 10% of Man's past history -
why don't we examine these anomalies with an open mind?
