Parabolic mirrors were described and studied in classical antiquity by the mathematician.A number of experiments with curved polished iron mirrors, and discussed plane, convex spherical, and concave spherical mirrors in Optics. Parabolic mirrors were also described by the physicist Ibn Sahl in the 10th century, and Ibn al-Haythamdiscussed concave and convex mirrors in both cylindrical and spherical geometries, carried out a number of experiments with mirrors, and solved the problem of finding the point on a convex mirror at which a ray coming from one point is reflected to another point. By the 11th century, clear glass mirrors were being produced in Moorish Spain.
Then you can see that Archimedes used spherical mirrors to burn enemy battle ships.
Archimedes is also have a great hand in the civilization of the mirrors .
