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
The reading states that a set of clay jars were excavated by local people which belonged to 2,200 years ago in Iraq, and 2 years later in 1938 an archeologist proposed that these vessels were the first ancient batteries because they can generate a small current of electricity. However, the speaker finds all dubious and presents some facts to refute them all.
First, the writer states that there was not any evidence of wires or conductors such as metal which is essential to produce the electricity. Conversely, the professor pointed that the clay jars were found by local untrained people who were not archeologist and they might not recognize the importance of other materials found near the archeological site.
Furthermore, the reading said that there were some copper cylinders inside the jar which were resemble to that of discovered in the ruins of Seleucia, located nearby, and used for holding scrolls of holy texts. In contrast, the speaker underlies that the ancient people might use copper cylinders firstly as a holder for scrolls but during time the in combination with wires they might have invented ancient batteries for other purposes.
Finally, the author stated that ancient people had not invented any electrical devices, consequently batteries were completely useless. On the contrary, the professor dismisses this issue and brings the fact that a light current of electricity might had used to persuade others by ancient people that they had magical power. Additionally, in these days the weak current of electricity may use to stimulate some parts of the body for healing from pain.
