burning mirror
Some controversy has been generated about whether or not the Greek used buring mirror to defend themselves. The reading states that the Greek did not use a burning mirror for three possible reasons. However, the professor arguse that none of the three points are convincing.
The first point of dispute is if Greeks were sophisticated enough to create the burning mirror. The lecturer explains that what the writer said about the advanceness of the ancient Greeks is totally wrong. The ancient Greek were able to use small pices of the mirrors to make a large parabolic curvature. By contrast, the writer casts doubt on this claim by saying that making a such device was impossible during the ancient time.
The second controversial issue is about the length of the time that burning mirror was needed to start a fire. According to the professor, the reading passage only present the starting fire in wood parts of the ship. Yet, shipes were actually made of several materials. So the burning mirror can start a fire on a ship in just secondes if it ctachs the pitch which is the substance that used to glue the wood parts together. On the other hand, the author claims that a device such as burning mirror would not have been good enough to start fire quickly.
The final point of debate is the question of using burning mirror instead of the flaming arrow. The speaker posits that the ancient Greeks could have used new type of weapon because Roman navy would notice the flaming arrow, and they could put off the fire. However, using the burning mirror happens in seconds without allowing the Romans to see it. Thus, burning mirror could have been much effective as weapoin than the flaming arrow. Despite that possible rationale, the author ignores these potential explanations.
