It is believed that the concept of burning mirror, that the Greeks used to defend themselves against roman attack, might have been a myth and several reasons are given to support the argument. But there are other possible explanations that credit the feasibility and advantages of this concept. The reasons are discussed further.
To begin with, the Greeks may not have needed the capability of manufacturing a large parabolic mirror, instead they could have achieved it using small mirrors. Thus eradicating the need of single wide sheet of copper. And the Greeks were abreast of knowledge they needed to arrange these mirrors so as to concentrate the heat from sunlight on one point.
In addition, the argument that these mirror would have taken a considerable amount of time to set wood on fire condones the fact that ship is constructed using other materials also. The glue know as Pitch that was used for water proofing and holding the wood together was capable of catching fire in seconds when subjected to such amounts of concentrated heat. The Greeks would have used their mirror to heat up this glue which in turn light up the wood.
Furthermore, Roman soldiers would have been aware of these flaming arrows. They would have arranged for setting off the fire caused by this arrows. However, it would have not been possible for the Roman soldiers to block the heat from burning mirrors. Therefore, it would have been an effective weapon against the Roman ships.
Conclusively, for the above reasons it was both advantageous and feasible for Greeks to use burning mirrors to defend themselves against the Roman invasion.
