In hieroglyphic writing the symbol used to denote eternal life, the ankh, was also used to represent copper. The Greek philosophers later adopted the symbol, slightly modified, as . The connection between eternal durability and the lifetime cost-effectiveness of copper and its alloys is surely not coincidental! The Egyptians obtained most of their copper from the Red Sea Hills, but copper predates ancient Egypt by several millennia, and it is now known that an old
