Mirrors, ancient egypt

Only when man had learned to produce bronze, stone tools were completely replaced with bronze ones. Most likely bronze was first obtained by chance. This is evidenced by the archaeological finds on the island of Crete dating back to about 3500 B.C. which revealed not only copper but bronze articles as well. At first bronze was rather expensive and was used mainly for jewelry and luxury articles. In ancient Egypt mirrors were made from bronze. Bronze, like copper, proved to be an excellent material for relict makers and sculptors. As early as the 5th century B.C. man learned to cast bronze statues. Particular progress in bronze sculpture was made in ancient Greece beginning with the Mycenaean period. At our times copper and bronze still retain this role. 

The childhood of optics was in ancient religious Egypt. The first survived written relics of the optics originates from antique Greek science. Euclid was regarded as one of the founders of geometric optics because of his books on optics and catoptrics (catoptric light, reflected from a mirror).
