according to some ancient historians, the Greek defended themselves with an ingenious weapon called a "burning mirror", for war with the roman navy. this claim that expressed in the passage is impractical and entirely unconvincing. the first reason, they could do not produce a large flat polished copper because its materials did not exist and we know, a mirror that would focus sunlight with sufficient intensity to set ship on fire would have tobe several meters wide. the second reason, the burning mirror would have to take a long time to set the ships on fire, it approximately take ten minutes time for setting fire so that is not quick enough for attack. therefore, such a weapon would have been very ineffective. the third reason, the Greeks probably were familiar with this weapon but they did burning with flaming arrows but this weapon is effective for a few distance so the Greeks have to produce a better and more effective weapon like burning mirror.
