The reading passage discusses an interesting topic about the an ancient Greek weapon called burning mirror and how it is believed to be just a myth, providing three reasons for support. However, the lecturer casts doubt on the claim made by the article. She thinks there are good evidences to believe in the existence of this weapon and refutes each of the reasons of the reading passage.
First, the article sustains that the technology was not advanced enough to build that size of mirror built with the purpose to burn a ship with the sun's rays from the distance. On the contrary, the lecturer explains how Greeks could manage to gather many small pieces of cooper mirrors and glued together over the big parabola shape surface to produce the burning effect.
Secondly, the reading passage argues that the time required to burn a ship with the burning mirror, according to experiments done, is too long: ten minutes. Challenging this point, the lecturer suggests that the preferred target to burn was not the wood of the ship but the pitch. This part of the ship could be burned in seconds.
Finally, the article argues that the burning mirror had no point to be created when Greek soldiers could use the burning arrows from same distance. The lecturer disagrees with this idea by mentions that the burning mirror's main characteristic was the surprise factor, which the arrow did not presented.
