Summerise the points made by the lecturer and how they refute the author's points.
The lecturer and the author both discuss the Roman navy attack on the Greek port city of Syracuse and the use of mirrors to burn enemy ships from afar during the battle. The author provides three points to undermine this historical theory; however, the lecturer challenges those ideas by providing counter-arguments to the author’s.
To begin with, the author argues that the ancient Greeks did not possess sufficient knowledge and technology to create single sheets, several meters wide, with specific parabolic curves, to set fire to enemy ships. On the contrary, the lecturer points out that these mirrors could be made of several smaller sheets. Moreover, she argues that the Greek mathematicians had sufficient knowledge of parabolic curves to form the specific curvature needed for the mirror to focus sunlight.
Next, the author claims that a prerequisite for a successful attack is for the burning mirror to be focused on a single point for a long time, which would be unlikely with enemy ships continually moving. To further support this idea, he discusses an experiment in which it took 10 minutes for a wooden object to ignite with burning mirrors. In contrast, the lecturer questions the author's assumption of setting fire to the wood. She explains that what the burning mirrors would set fire to, was not the wood itself but the materials used in the gaps of the wooden panels to make the vessels waterproof. She says that these materials would quickly and in seconds combust with burning mirrors, leading to a widespread fire on the ship.
On the last note, the author proposes that the Greeks possessed another effective weapon, flaming arrows, for fighting approaching ships on the see, thus making the use of burning mirrors obsolete. Yet again, the lecturer argues that the Roman soldiers would be aware of flaming arrows and would be prepared to put the fire out. Conversely, they could not see the rays of light from burning mirrors and would be caught off guard if suddenly their ships would catch fire, which would make the burning mirrors an effective weapon.
To conclude, the author suggests three points to undermine the theory of Greeks using burning mirrors in the Roman invasion. At the same time, the lecturer presents counterpoints to the author's statement, rebutting his argument.
