                   First Mirrors

   The first known mirrors were recovered from graves in
    Anatolia modern Turkey. The cemetery was dated
    approximately 6000 to 5900 BC.
   These mirrors were made from ground and polished
    obsidian (a volcanic glass) and had a round reflective
    surface. They were slightly convex, highly polished, and
    approximately 9 cm in diameter.

               Egyptian Mirrors

   The Egyptians used mirrors around 4500 BC.
   These mirrors were wetted ground stone palettes. They
    could make good images but the water evaporated very
    rapidly from their surfaces.
   From approximately 4000 to 3000 BC, small copper
    disc mirrors were recovered in the Tigris-Euphrates
    Valley in Southern Mesopotamia, now Iraq. From then
    on, records of mirror use appeared within sculptures,
    carvings, texts, and as actual mirrors.

                Mirrors in China
   In China mirrors were first located around 2000 BC.
   Early Chinese mirrors ranged from 6 to 12 cm in
    diameter, were not ornate, and had a centered pierced
    knob used to hold the mirror on the back surface.
   The mirrors were generally thin, and raised ridges
    included in patterns on their rear surfaces possibly
    provided some rigidity. Copper alloys or bronze were
    used early, and handles appeared later.

   In Mexico, they were made by the Olmec, Mayan, and

   In Peru, the Chavin culture (900/800-200 BC),
    developed polished anthracite mirrors.
   The Moche culture (200 BC-600 AD),had copper-
