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.
Both the lecture and the passage talks about the possibilty that the vessel found in iraq is the first source of electricity. The readig disapproves its authencity not be source of electricity, but while the lectue butress the point by deducing the logical explanation.
first, the lecture says that the intrument found by the naive people of the village not the archeologist. she opens a door of chance that it was battery by saying that people got this may overlooked the other details which were associated with it; they might throw the wire and other stuff in the process. giving this explanation, she clearly resurgent the idea that the vessel is first made battery.
Second, although she concedes that it is similar to the copper cylinder of the Seleucia which was used to carry the scroll, but argues its possibilty of being battery. she hypothesizes that ancient people of iraq might realize that it could be used as battery if it was connected with copper or iron wire. this explanation brings the vessel possibility as a battery.
Lastly, the speaker refuses the view of no use of battery at that time. she mentions that people might use it to make beileve other people in magic. On the other hand, she addes that it may be used as a medical procedure to give mild tingling sensation to the people. The electic function to serve as means of curing pain and ache may be strong enough to support the claim thye vessel as the battery.
