Taking a break from creepy creatures or what-have-you popping up in windows and doors, today we have something much more normal. But still weird.
In 1936, while excavating a 2000 year old village near Baghdad, a small, strange vase was discovered.
The vase was 6 inches high and made of bright yellow clay. Also, the clay was dated back two millenia.
On top of that, the vase contained a cylinder of sheet copper 5 inches by 1.5 inches and the edge of the copper sheet was soldered with a lead tin alloy similar to today's solder. The bottom of the cylinder was capped with more copper and sealed and the top was sealed in order to hold in place an iron rod suspended in the center of the copper cylinder. The rod had been corroded in places by acid.
Archaeologists examined the artifact and came to the surprising conclusion that it was, in fact, an electric battery, made 1800 years before their invention in 1799.
Replicas made of this battery (and others found in roughly the same region (close to a dozen in total)) show that the batteries could produce from .8 to nearly 2 volts of electricity.
Unfortunately, no one really knows what they were used for. Some people think they were used for pain killing, though opium and other, better, pain killing options were already in use at the time.
They could have also been used to electroplating - transferring a thing layer of metal onto another metal surface - but there hasn't been any artifacts discovered in the region with this kind of decoration or effect.
Or maybe they were just used as some sort of magical ritual. If you don't understand the science you created, it would be easy to say that touching an idol would give you a tingle.
Either way, it certainly changes the way, once again, we think about the past and the people who lived there.
Thoughts?
