A 2300 Year Old Battery? 15 Rare Historical Artifacts You Won't Believe Exist!
The Baghdad Battery is one of the interesting and unique items featured in the video below.
There is no written record as to the exact function of the jar, but the best guess is that it was a type of battery. Scientists believe the batteries (if that is their correct function) could have been used to electroplate items such as putting a layer of one metal (gold) onto the surface of another (silver), a method still practiced in Iraq today.

"The König hypothesis, as a hypothesis, isn't quite as far out there as it sounds. His speculation was based in part on the observation that the iron rods appeared to have been corroded by contact with an acid. In modern times, electroplating was discovered multiple times independently within a few years of the invention of the galvanic cell. If an ancient inventor happened to assemble something that functioned as a battery, there is no particular reason why the discovery of electroplating could not follow. However, there is no evidence whatsoever that this actually happened, and no ancient electroplated artifacts have been identfied." Wiki has more great detail on the battery / container.
Though the object is capable of producing current, because tests and data on the objects discovered has not been conclusive to the functionality, Benjamin Franklin, Thomas Edison, and Nickola Tesla have not been usurped by historical sciences.
