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 and the lecturer are about clay jar vessels. More specifically, in the reading passage, the writer provides three pieces of evidence to show that the vessels do not conduct electricity. The lecturer is quick to point out that there are some serious flaws in the writer's claim. In fact, he believes and addresses in detail the trouble with each claim made in the reading text.
First and foremost, the author of the reading states that if they are true batteries they would be seen on some conductors such as metal wires. The lecturer, however, stands in firm opposition to this claim. He states that batteries are clear because wires are absent. Moreover, vessels are discovered by village people and they might have come across some materials that conduct electricity, but since they are not trained archaeologists they might be able to picture what the materials contain.
Secondly, the author of the reading feels that the copper cylinder inside the jar is synonymous with that found in the ruins of Selucia. The lecturer, however, stands in firm opposition to this claim. He states that copper cylinders are preserved in Seleucia such that it used with an iron rod and some vessels will produce electricity.
Finally, the author brings his argument to a close-by suggesting that what would people in the past do with electricities that were supposed to be produced. Not surprisingly, the professor rebutted this claim by contending that batteries generate shock and tingling which could serve as a piece of evidence that they are conductors. Also, it convinces people because they do see batteries as magical powers and because they can be used as therapy this actually made doctors make use of it while treating their patients.
