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 claims that the archaeologist’s proposal that vessel were ancient batteries is unlikely. However, the lecturer finds all the ideas dubious and provides some evidence to refute them all.

The reading asserts that batteries need to be attached to some electrical conductors such as metal wires but all the things which are excavated are the vessels themselves. In contrast, the professor brings up the idea that the vessels were found by local people, not by trained scientist. The absence of a conductor doesn’t prove anything. The people may have thrown them away because they did not recognize the importance of them.

Furthermore, the reading passage holds the view that the cylinders found with jars are identical to the copper cylinders from Seleucia which were used for holding scrolls of sacred texts. Therefore the cylinders were also used for the same purpose. The absence of scrolls is explained by the fact that the scrolls simply disintegrated over the centuries. Conversely, the speaker dismisses this issue due to the fact that over the time, ancient people could have adapted the cylinders to use for other purposes and the reading's claim does not prove anything.

Finally, the author claims that the vessels could not have any function as a battery for ancient people since they had no device to reply on electricity. On the contrary, the professor underlines the fact that ancient people used to take advantage of electricity to produce a mild shock or some people used it as an invisible and magic power. They also used electricity for hilling or some scholars used it to stimulate muscles to relieve pain.
