Reading and lecture discusses whether the theory of an ingenious weapon named burning mirror used by Greek to cause fire on Roman ship to save themselves 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 determine the method to focus sunlight on ship to cause fire. Furthermore, large copper sheets were not invented at that time to create this weapon. The professor casts doubt on the 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 Mathematicians were cognizant clever to create a parabola shape out of copper sheets.
Second, reading argues that Roman ship must be steady for ten minutes in order to catch fire by burning mirror. However, professor challenges this point. She thinks that burning mirror can create fire in ship quickly due to sticky waterproof material called pitch glued on the surface of wooden ship. In addition, she says that Roman ship could have easily burnt even if ship was in motion, there was no requirement for ship to be static to spread fire.
Thirdly, reading states there was no valid reason for Greeks to make burning mirror, because they were expert in shooting burning arrow to destroy enemies from far distance. In contrast, professor thinks that attacking Roman soldiers could easily spot these flaming arrows, as they were familiar with that type of attack, so they are not effective weapons. Furthermore, professor adds that burning mirrors are invisible, thus they can set ship on fire without even noticing by anyone. Hence, professor successfully challenged statements made in reading.
