The reading discussed several theories to suspect the existence of the burning mirror, a weapon used by ancient Greeks to defend themselves. However, the lecturer finds the ideas dubious and casts doubts on the reasons provided by the reading passage.
First, the author argues that according to the size and precise geometric shape of burning mirrors, it was technologically impossible for ancient Greeks to manufacture such a device with a large sheet of copper. Conversely, the lecturer brings up the idea that it could have been possible for Greeks to build the device since many polished copper sheets could have been merged in order to form a large sheet. Moreover, they had sufficient knowledge about the geometric shape of a parabola. Therefore, it seems possible that they could have formed the curvature by assembling small sheets.
Furthermore, the reading passage holds the view that based on an experiment’s results, the burning mirror would have needed a long time to set the ships on fire and during the time the ships should have been stayed still. On the contrary, the professor holds the view that the experiment has been conducted on wood. However, although most parts of their ships were made out of wood, other materials existed on the ships including a sticky substance which could catch fire in seconds and after being set on fire, it could spread the fire to other parts of the ship like woods. Therefore, the device could have been more advantageous than what the author believes.
Finally, the reading asserts that other weapons including flaming arrows had the same functionality. So, building such a weapon would have had no more benefits. In contrast, the speaker dismisses the issue due to the fact that flaming arrows were visible from distance. Therefore, the soldiers could easily track them and extinguish the fire quickly after they had reached their ships. On the other hand, the burning mirror was more efficient regarding the fact that while being used, the beams were not visible and the only visible thing from distance was a mirror. Therefore, the fire could have been more surprising and thus the weapon would have been more effective.
