Most shields weren’t metallic in the back, they were wooden. Only with metal plates partially or fully covering the front..

Study how shields were made, there are quite a few commonalities when it comes to most shields from the Roman Scutum to the Spartan Hoplon..

Interesting dates:
glass bottles and utensils 3000 BC
parabolic history 380 BC
Archimedes — 287 BC – 212 BC

If Archimedes was only as smart as am 8-year-old his death-ray would be more of a huge magnifying glass.

Archimedes knew all about parabolas. From his Wikipedia entry:

Archimedes is generally considered to be the greatest mathematician of antiquity and one of the greatest of all time.[2][3] He used the method of exhaustion to calculate the area under the arc of a parabola with the summation of an infinite series, and gave a remarkably accurate approximation of pi.[4] He also defined the spiral bearing his name, formulae for the volumes of surfaces of revolution and an ingenious system for expressing very large numbers.

now that i think of it, the invention that comes to my mind a solar dish powered by a few led light. out put will be way more then energy used i guarantee it… can then boil water! on a few volts only.. use a jewel thief circuit in connection to the led lights positioned at the focal point.

hi all i am an inventor, the truth to this mystery is very sinister indeed. Obama is a lire and of course the idea was perpetuated as many giant mirrors. obviously the fact remains that i had also reconciled the hidden message. the smaller the mirrors the greater the power. end story.

Am I the ONLY person in the world (including the US president) who noticed that Mythbusters didn’t actually test the real “Archimedes Death Ray” myth, and so couldn’t have busted it one way or the other? The REAL myth is that a flammable liquid known as “Greek fire” was spread on the water, and then the beams of light were used to combust the flammable liquid, and so burn the ships. How could they possibly miss this? Why didn’t they test the original myth, or was it too technically difficult? Am I the only person in the world who actually reads?
