Summerise the points made by the lecture and explain how she disagrees with the author's points.
The lecturer and the author of the passage both discuss the Roman navy attack on the Greek port city of Syracuse. More specifically, they discuss the validity of the use of burning mirrors during this war. The author provides three points to undermine this historical theory; however, the lecturer challenges those ideas by providing an opposing perspective.
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. She also points out that the Greek mathematicians knew parabolic curves to form the specific curvature needed for the mirror to focus sunlight.
Next, the author claims that the burning mirror would have to be focused on a single point on the ships for a long time to start a fire, which would be unlikely with ships continually moving. He discusses an experiment in which it took 10 minutes for a wooden object to catch fire with burning mirrors to support his statement. The lecturer questions the author's assumption of burning wood with the mirrors. She explains that what the burning mirrors would set on fire was not the wood itself but the materials used in the gaps of the wooden panels to make the ship waterproof. She says that these materials would quickly and in second combust with burning mirrors, and the fire spreads onto the rest of the ship.
On the last note, the author states 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. However, 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 and effective weapon.
To conclude, the author illustrates 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 and their validity.
