TPO 30 Burning mirror
In the lecture, the professor asserts that the claims made in the reading about the burning mirror being impractical and ineffective weapons are unconvincing. This casts doubt on the reading which states, however, there are 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.
First and foremost, the speaker posits that Greeks did not need a large single sheet of copper to form a big burning mirror. In fact, the experiment has shown that single flat pieces of polished copper can form a parabolic shape. Furthermore, because mathematicians knew the properties of parabola, they could direct the assembly to construct a parabolic figure. This contradicts the text, which proclaims the technology for manufacturing a large sheet of copper with such specifications did not exist in the ancient world.
Moreover, the lecturer argues that the burning mirror would not have taken as long as 10 minutes to start a ship’ fire . Actually, these ships were not made entirely of wood but also from other materials called pitches that could work quickly enough to put on the fire. For example, Romanians used these sticky substances to seal pieces of wood together and make them waterproof. Therefore, they could have needed a few seconds to set the ship into fire even if the ship was moving. This opposes the reading, which declares that it is unlikely that Roman ships stayed perfectly still for that much time, for this reason, weapons would have been very impractical and ineffective.
Finally, the professor explains that despite they had the flaming arrows, Greeks had to build a burning mirror as a device to defeat themselves. In fact, because the Romanian' soldiers were familiar with arrows, they would have been watching for them and taking caution. For example, they could see just the mirror with no burning rise in the mirror then all a sudden, surprisingly magical fire occurs in a ship. Consequently, this tool has been more surprising and effective that flaming arrows.
