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 jar contained a copper cylinder surrounding an iron rod. The archaeologist proposed that 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 passage expressed that the ancient people did not use that vessel as electric batteries in ancient time while the archaeologists proposed that vessels were ancient electric batteries. according to the lecture, this statement is not exactly true. in the ancient time there was not wire but other material was exist that the ancient people could use those for creating electricity. the copper cylinders inside the jars look exactly like copper cylinders, we suppose the ancient people used copper structures for producing electricity since the cylinders found with the jars have the same shape, it is very likely they were used for holding scrolls as well. the battery have very visible power and there is possibility for ancient people that use the battery for shocking, I mean they could use it for healing some disease as it is using by the present doctors for healing inactive muscles.
