214 BC invented
Archimedes invented a weapon to set fire to ships. It was based on what Anthemius of Tralles called "burning-glasses" perhaps mirrors or lenses used to focus sunlight onto the targeted ships, causing them to ignite.

Parabolic Reflector Archimedes may have used mirrors acting collectively as a parabolic reflector to burn ships attacking Syracuse.
Parabolic Mirror Parallel rays coming into a parabolic mirror are focused at a point F. The vertex is V, and the axis of symmetry passes through V and F. For off-axis reflectors (with just the part of the paraboloid between the points P1 and P3), the receiver is still placed at the focus of the paraboloid, but it does not cast a shadow onto the reflector.
