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 excerpt states that the vessels which are a set of clays that had been excavated two years earlier by villagers constructing a railroad line were not used as electric batteries in ancient times, the author provides three reasons for support. However, the lecture's audio claims that there are a lot of problems with the author theories and she refutes each of them.
To begin with, the article avers that if the vessels were used as batteries, they would probably have been attached to some electrical conductors such as metal wires. In contrast, the professor opposes this point of view by saying that these vessels found out by loco people who were not trained for such a task. So, they might found other things and they did not recognize them. Hence, these wires or conductors might be thrown away. Therefore, this point is not convincing.
Second, the passage posits that the copper cylinders inside the jars look exactly like copper cylinders discovered in the ruins of Seleucia, an ancient located nearby. On the other hand, the speaker asserts this outlook and explains that it is right these copper cylinders were used for holding but that not prove anything because many ancient civilizations had been used the cooper with the iron to produce electricity. Thus, even if they were used for holding purpose, they might be adapted to another purpose after that. So, this theory is definitely wrong.
