Burning mirror
The article and the lecture are both about the authenticity of burning mirror, a weapon is said to be used by the Greeks to fight against Roman. The author of the reading is of the opinion that this is not real and provides three reason to support it. The lecturer refutes the statements made by the author. She believes that evidence for belief that burning mirror is impossible and technologically impractical is unconvincing.
First, the author suggests that Greek at the time were not capable of constructing such a huge sheet of copper in the shape of the parabola to build the weapon. This argument is challenged by the lecturer. She says that there was no need to produce a single big piece. She puts forth idea that the device may be comprised of dozens of flat copper sheets gathered in the form of parabolic curve.
Second, the writer contends that it would take ten minutes to burn an object made of log in the condition that the object must stand still during the process, as displayed by an experiment. This is, is according to the writer, impractical during the battle time. The lecturer, however, rebuts this point by asserting that the experiment is based on the assumption that flame was to burn the wood directly. However, Romans' boats are not only made of wood but also others, for example, a materials to be painted on the log to make them waterproof. This one can, nevertheless, catch the fire in only seconds, and subsequently spread to woods even if the ship were moving. Therefore, the burning mirror was, in fact, a powerful instrument.
Finally, it is stated in the passage that the Greeks would not bother to construct burning mirror because they already owned flaming arrows - another weapon of the same usage and effectiveness. The lecture, on the other hand, posits that as flaming arrows were already prevalent, the Romans would be alert and prepare for their attack. Meanwhile, they can only see the mirror from faraway and the fire started suddenly without being observed. This method created more surprise, therefore, made the tool more effective.
