In 1938 an archaeologist in Iraq acquired a set of clay jars that had been excavated two years earlier by villagers constructing a railroad line. The vessel was about 2,200 years old. Each clay jay contained a copper cylinder surrounding an iron rod. The archaeologist proposed that vessel were ancient electric batteries and even demonstrated that they can produce a small electric current when filled with some liquids. However, it is not likely that the vessels were actually used as electric batteries in ancient times.
First of all, if the vessels were used as batteries, they would probably have been attached to some electricity conductors such as metal wires. But there is no evidence that any metal wires were located near the vessels. All that has been excavated are the vessels themselves.
Second, the copper cylinders inside the jarslook exactly like copper cylinders discovered in the ruins of Seleucia, an ancientcity located nearby. We know that the copper cylinders from Seleucia were used for holding scrolls of sacred texts, not for generating electricity. Since the cylinders found with the jars have the same shape, it is very likely they were used for holding scrolls as well. That no scrolls were found inside the jars can be explained by the fact that the scrolls simply disintegrated over the centuries.
Finally, what could ancient people have done with the electricity that the vessels were supposed to have generated? They had no devices that replied on electricity. As batteries, the vessels would have been completely useless to them.
The reading and listening materials have a debate on the use of the vessel found by local villagers. The author believes that vessel was unlikely to be used as electric batteries, While the following speaker holds an opposite view.
First, the author claims that the lack of electricity conductors such as a wire attached to the vessel is a proof that the vessels weren't used as electrical batteries. The speaker explains that excavation was done by the local villagers and not archaeologists, therefore, It is not precise. they could have missed or overlooked some materials or even throw away an important materials serving as wire due to their ignorance.
Second, the author points out to a similarity between these copper cylinders and the ones discovered in ruins of Seleucia. The copper cylinders found in Seleucia functioned as sacred scroll's preserver hence the vessel should act in the same way. The speaker refutes this point by saying it is true that originally the copper cylinder might have originally used as a mere scroll holder. However, an ancient inventor may have found that with use of iron rod and some liquid it can produce electricity. So the cylinder copper maybe originally used for one purpose and later on adapted for a new purpose.
Lastly, the author argues that there was no device in ancient time which could use generated electricity by vessel. The professor mentions other use of generated electricity like producing a mild shock to convince superstitious people of having magic power or use it for healing as modern doctors do by stimulating muscles for muscle's growth or reducing pain.
