Hedjet (Ancient Egyptian: ḥḏt "White One") is the formal name for the White Crown of pharaonic Upper Egypt. After the unification of Upper and Lower Egypt, it was combined with the Deshret, the Red Crown of Lower Egypt, to form the Pschent, the double crown of Egypt. The symbol sometimes used for the White Crown was the vulture goddess Nekhbet shown next to the head of the cobra goddess Wadjet, the uraeus on the Pschent.
The white crown, along with the red crown, has a long history with each of their respective representations going back into the Predynastic Period, indicating that kingship had been the base of Egyptian society for some time. The earliest image of the hedjet was thought to have been in the Qustul in Nubia. According to Jane Roy, "At the time of Williams’ argument, the Qustul cemetery and the ‘royal’ iconography found there was dated to the Naqada IIIA period, thus antedating royal cemeteries in Egypt of the Naqada IIIB phase. New evidence from Abydos, however, particularly the excavation of Cemetery U and the tomb U-j, dating to Naqada IIIA has shown that this iconography appears earlier in Egypt".
Stan Hendrick, John Coleman Darnell and Maria Gatto in 2012 excavated petroglyphic engravings from Nag el-Hamdulab in Aswan, the extreme southern region of Egypt that borders the Sudan, which featured representations of boat procession, solar symbolism and the earliest depiction of the white crown with an estimated dating range between 3200BC and 3100BC.
Nekhbet, the tutelary goddess of Nekhebet (modern el Kab) near Hierakonpolis, was depicted as a woman, sometimes with the head of a vulture, wearing the white crown. The falcon god Horus of Hierakonpolis (Egyptian: Nekhen) was generally shown wearing a white crown. A famous depiction of the white crown is on the Narmer palette found at Hierakonpolis in which the king of the South wearing the hedjet is shown triumphing over his northern enemies. The kings of the united Egypt saw themselves as successors of Horus. Vases from the reign of Khasekhemwy show the king as Horus wearing the white crown.
As with the deshret (red crown), no example of the white crown has been found. It is unknown how it was constructed and what materials were used. Felt or leather have been suggested, but this is purely speculative. Like the deshret, the hedjet may have been woven like a basket from plant fiber such as grass, straw, flax, palm leaf, or reed. The fact that no crown has ever been found, even in relatively intact royal tombs such as that of Tutankhamun, suggests the crowns may have been passed from one monarch to the next, much as in present-day monarchies.
