Reading and lecture discusses about whether the theory of a weapon called burning mirror fire is true or false.
Reading suggests that theory was myth, while professor thinks that explanation in reading is not cogent.
First, reading points out that ancient Greeks were not very intelligent to figure out
the method to focus sunlight on ship to cause fire. Furthermore, it also adds that large copper sheets were not available at that time to create this weapon. The professor casts doubt on statement made in lecture. She says that large copper sheet might not be created from single sheet, but Greeks might have arranged dozens of small sheets to form parabolic shape to reflect sunlight. In addition, she also points out that Greeks were clever to perform fine task for creating huge copper sheet.
Second, reading argues that Roman ship must be un moving for ten minutes in order to catch fire by burning mirror. Furthermore, it states that this burning weapon might take another thirty minutes to burn wood, so use of this weapon is impractical. However, professor challenges this point. She thinks that burning mirror can create fire in ship quickly due to waterproof material called pinch glued on the surface of wooden ship. In addition, she brings fact all these procedures can happen when ship is moving.
Thirdly, reading states there was no valid reason for Greeks to make burning mirror, because they were expert in shooing burning arrow to destroy enemies from far distance. In contrast, professor thinks that attacking soldiers can easily spot these burning arrows, so they are not logical in defense. Furthermore, professor adds that burning mirror can not be seen by human, thus burning mirror can set on fire without even noticing. Hence, professor successfully challenged statements made in reading.
