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 vessels were about 2,200 years old. Each clay jar contained a copper cylinder surrounding an iron rod. The archaeologist proposed that the 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 reading passage and the lecture talk about the vessels used as electronic batteries in ancient times. Despite that, the professor thinks the arguments in the reading are not correct. She casts doubt on every single point the reading make and provides details to support her idea in the lecture.
To begin with, the reading indicates that there is no metal wires found near the vessels, hence, it is not possible that the vessels were used as batteries. However, the lecturer argues that the vessels were found by the local people. They might find other materials but they did not provide them to the archaeologists. These material may been overlooked or thrown away already. As a result, she can not give a nod to the author in terms of the first point.
Secondly, about the shape of the copper cylinders, the writer thinks the purpose of the copper cylinders is likely to be holding scrolls of sacred texts whereas the professor pointed out the similar shapes can not prove its purpose. It is possible that the vessels were utilized for holding scrolls at the first but later applying to electricity purpose. In other words, they adapted to another purpose in the end. Apparently, she disproves its counterpart in the reading.
In addition, the author suggests that there is no devices required electricity in that time. The speaker, on the other hand, believes it could be used as an invisible power for magic purpose. Or it could be healing purpose to stimulate the muscle to reduce the pain. Hence, she can not support the opinion of the third point.
To sum up, the writer and the professor have conflicting views on this topic.
