A little over 2,200 years ago, the Roman navy attacked the Greek port city of Syracuse. According to some ancient historians, the Greeks defended themselves with an ingenious weapon called a “burning mirror”: a polished copper surface curved to focus the Sun’s rays onto Roman ships, causing them to catch fire. However, we have several reasons to suspect that the story of the burning mirror is just a myth and the Greeks of Syracuse never really built such a device.
The reading asserts that in 2200 years ago, the innovative weapon that Greek was equipped with, which was called 'burning mirror', against the Roman navy is just a myth and it is not true that Greek ever constructed such an apparatus. The lecture, however, finds this intention dubious and casts doubt on the reasons proposed by the reading passage.
First, the author argues that the ancient Greek was not technologically able to build such a big advanced device that would have had several meters with. In addition, it is far that in the ancient Greek had enough technological equipment to build a precise mirror. Conversely, the lecturer brings up the idea that that big mirror was constructed from dozen polished copper. Therefore, constructing and assembling these small mirrors did not need advanced technology.
Furthermore, the reading passage holds the view that as an experiment has indicated, using the burning mirror, it takes a long time to set a ship, composing wood, on fire. So, this device was not applicable and useful. On the contrary, the professor underlines the fact that the Roman ships were not constructed only from wood. The ships had a sticky cover that could get fire in just seconds. Therefore, the ships did not need to be unmoved to get fire.
Finally, the reading claims that the Greek had already enough advanced weapon, like flaming arrows, so that they did not need to utilize a burning mirror. in contrast, the speaker dismisses this issue due to the fact that the Roman was acquainted with the weapon that Greek had. They could distinguish the equipment of flaming arrows from a far distance. But, the application of a burning mirror was surprising as the Roman was not familiar with this technology.
