00:00Archimedes allegedly used focused solar mirrors during the Siege of Syracuse.
00:05Historical accounts describe Archimedes using polished bronze mirrors to focus sunlight,
00:10though modern tests show mixed results.
00:13Arrayed bronze shields focused converging solar rays onto a single point of the wooden fortifications.
00:20Concentrated solar radiation rapidly elevated the temperature of the pitch-coated timber
00:25until it reached its flashpoint.
00:27Modern tests show concentrated solar rays could rapidly ignite combustible pitch on wooden targets.
