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 jars look exactly like copper cylinders discovered in the ruins of Seleucia, an ancient city 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 article introduces an archaeologist in Iraq who acquired a set of clay jars which have been found by villagers. Each of which contained a copper cylinder surrounding by an iron rod. He proposed that the vessel were ancient electric batteries. The author does not believe them to be batteries and states his opinions about it not being a battery. However, the professor does not consider his statements enough to prove that they were not batteries.
First, the article claims that since there were no conductors such as wires attached to them, they were something else. However, the professor points to the fact that they were discovered by villagers who was not trained archaeologists. Hence, they might be some conductors attached to them but have been considered not to be important and thrown away.
Second, the author claims that the copper cylinders were look alike cylinders discovered in Seleucia which were being used as holder for scrolls of sacred texts. Despite the lecturer agrees with this similarity but he deeply believes that this does not prove anything. He claims that they might be designed as holders at the first place but later they have been discovered to have such a capability.
At last, the author mentions that in ancient times they were no devices and applications to benefit from electricity and it would be nonsense to have batteries. The professor disagree with his statement and points to its probable uses. He claims that they might be used to produce electric shocks which might be considered magical power in those times or they might be used for some sort of healing like the therapies that benefit from electrical current nowadays.
