Around the close of the 3rd Dynasty, (circa 2575 BC) Huni used a cartouche to enclose his sovereign name. Over time the cartouche became vertically elongated to hold the cuneiform glyphs of longer royal names. A double-cartouche was sometimes used to display the royal name alongside the given, or birth name. Egyptians believed that writing down a name was important, or the soul risked being lost after death. This might explain why the cartouche appears on many royal sarcophagi.
The cartouche was such a powerful symbol that Tuthmosis III (1504 BC - 1450 BC) dictated his entire burial chamber, as discovered in the Valley of the Kings, be cartouche-shaped, along with his sarcophagus. Temple inscriptions from the Greco-Roman Period also show the cartouche holding names of gods, such as Osiris and Isis.
Today anyone can enjoy the royal blessing of a custom cartouche with his or her name in hieroglyphics. A cartouche can hang from a necklace, bracelet, or can be purchased as earrings. Custom cartouches come in many styles in both gold and silver.
Needless to say the females in our family now have one, although they have not received them YET!
