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 jar contained a copper cylinder surrounding an iron rod. The archaeologist proposed that vessels 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 relied on electricity. As batteries, the vessels would have been completely useless to them.
The essay tells that through excavation by the villagers they found clay jar contained a copper cylinder surrounding an iron rod which may be used as ancient electric batteries, but later they denied it as an electric battery. however, the speaker approached that, the thinking may not be true and not convincing, that's why she gives three examples on it.
First, from the essay, it is said that excavating vessels contains no electric conductors, which means there is no chance of using these vessels an electric batteries. On the other hand, the speaker states that as the vessels are excavating by the villagers who are not professional archaeologists. So, it is possible that they fail to notice the metal wire or they can't recognize it anyway.
Secondly, the essay states that these vessels exactly look like the copper cylinders discovered in the ruins of Seleucia and are used for holding scrolls of sacred texts. But, the speaker, in that case, gives another opinion. she provides information that the copper cylinder surrounding an iron rod may be used as the wire to produce electricity.
Finally, the paragraph asks a question about what could ancient people have done with the electricity that the vessels were supposed to have generated? To answer this question the speaker tells that these kinds of vessels may produce mild shock which some people in that time believe as magical power. Besides, these ancient people were so generous that, they use this electricity for healing because in modern time doctors use electric shock waves to treat their patients. so, It was not impossible in those ancient times.
