English: A conceptual diagram of an Archimedes heat ray. In practice, many more mirrors than shown would be needed, and the results may have been merely soldier sweat, temporary blindness, and confusion rather than fire. The mirrors may have consisted of polished metal and had peep-holes drilled in the middle for use in aiming.

He proposes that some Roman ships actually did catch fire and consequently sank. |
