The reading and the lecture discuss the burning mirror which was a polished copper weapon used by the Greeks to rebut the roman’s attack 2200 years ago. The author believes that the story of this mirror is just a myth and that the Greeks could not create such a weapon. The professor brings into question the claims made in the lecture. he considers that the technological and scientific reasons presented in the reading are unconvincing.
First, the author comes up with the idea that the Greeks did not enjoy a great technological advance to create the parabolic curvature and the copper specifications of the burning mirror in order to set on fire the enemy's boats. However, the professor argues that by the time mathematicians had figured out what was a parabola which allowed them to build such a curved mirror.
Second, the author states that the mirror needed a large amount of time to set the ships on fire. Besides, with today’s experiments, it has been proved that a piece of wood burns in 30 meters without being in movement. Meanwhile, the professor rebuts this argument by pointing out that the ships had other materials as well such as pitch which catches the fire instantaneously. therefore, it may be the cause of spreading the fire.
Finally, the author contends that the flaming arrows used by the Greeks in war may be enough to burn the roman’s ships. So, they had no need to create a burning mirror. The lecturer, on the other hand, posits that the roman’s troops were ready to put out the known flaming arrows of the greeks, as a result, the greeks may create the burning mirror in order to surprise their enemy with an accurate and sudden attack.
