The Uraeus (//; plural Uraei or Uraeuses; from the Greek οὐραῖος, ouraîos, "on its tail"; from Egyptian jʿr.t (iaret), "rearing cobra") is the stylized, upright form of an Egyptian cobra (asp, serpent, or snake), used as a symbol of sovereignty, royalty, deity and divine authority in ancient Egypt.
The Uraeus is a symbol for the goddess Wadjet. She was one of the earliest Egyptian deities and was often depicted as a cobra, as she is the serpent goddess. The center of her cult was in Per-Wadjet, later called Buto by the Greeks. She became the patroness of the Nile Delta and the protector of all of Lower Egypt. The pharaohs wore the uraeus as a head ornament: either with the body of Wadjet atop the head, or as a crown encircling the head; this indicated Wadjet's protection and reinforced the pharaoh's claim over the land. In whatever manner that the Uraeus was displayed upon the pharaoh's head, it was, in effect, part of the pharaoh's crown. The pharaoh was recognized only by wearing the Uraeus, which conveyed legitimacy to the ruler. There is evidence for this tradition even in the Old Kingdom during the third millennium BCE. Several goddesses associated with or being considered aspects of Wadjet are depicted wearing the uraeus as well.
At the time of the unification of Egypt, the image of Nekhbet, the goddess who was represented as a white vulture and held the same position as the patron of Upper Egypt, joined the image of Wadjet on the Uraeus that would encircle the crown of the pharaohs who ruled the unified Egypt. The importance of their separate cults kept them from becoming merged as with so many Egyptian deities. Together, they were known as the nebty or The Two Ladies, who became the joint protectors and patrons of the unified Egypt.
Later, the pharaohs were seen as a manifestation of the sun god Ra, and so it also was believed that the Uraeus protected them by spitting fire on their enemies from the fiery eye of the goddess. In some mythological works, the eyes of Ra are said to be uraei. Wadjets existed long before the rise of this cult when they originated as the eye of Wadjet as a cobra. Wadjets are also the name of the symbols called the Eye of the Moon, Eye of Hathor, the Eye of Horus, and the Eye of Ra—depending upon the dates of the references to the symbols.
As the Uraeus was seen as a royal symbol, the deities Horus and Set were also depicted wearing the symbol on their crowns. In early ancient Egyptian mythology, Horus would have been the name given to any king as part of the many titles taken, being identified as the son of the goddess Isis. According to the later mythology of Re, the first Uraeus was said to have been created by the goddess Isis, who formed it from the dust of the earth and the spittle of the then-current sun deity. In this version of the mythology, the Uraeus was the instrument with which Isis gained the throne of Egypt for Osiris. Isis is associated with and may be considered an aspect of Wadjet.
Golden Uraeus of Senusret II
In 1919, after only a half-hour of excavation, the Qufti worker Hosni Ibrahim held in his hands the solid-gold Golden Uraeus of Senusret II. It had been decided to make a (follow-up) complete clearance of the El-Lahun Pyramid's rooms at Saqqara. The start in the rock-cut offering chamber, leading from the tomb, on the south, immediately revealed in the turnover of the six inches of debris, the Golden Uraeus crown ornament.
Prior to the 1922 find of Tutankhamun's tomb, this Golden Uraeus was the only ornament ever known to be worn by an entombed pharaoh, and it was thought that it was passed to the next pharaoh.
The Golden Uraeus is of solid gold, 6.7 cm (2.6 in), black eyes of granite, a snake head of deep ultramarine lapis lazuli, the flared cobra hood of dark carnelian inlays, and inlays of turquoise. For mounting on the pharaoh's crown, two loops in the rear-supporting tail of the cobra provide the attachment points.
As a hieroglyph
|Uraeus—Uraeus on BasketNtr + Cobra|
- For Uraeus ornament as a mummy grave example, See: Djedptahiufankh, High Priest of 21st Dynasty, Shoshenq I.
The simplest hieroglyph is the "Cobra" (the Uraeus); however there are subcategories, referring to: a goddess, a priestess, the goddess Menhit, the shrine of the goddess (àter), the goddess Isis, and lastly goddess: (Cobra (Uraeus) at base of deity (ntr)).
The Rosetta Stone uses the plural of the last example, "3 × "god flag" with Cobra at each base of flag". The story of the Rosetta Stone has the king (the priests of the king) listing his reasons for being honored, and in return, "The Gods and Goddesses (plural)" reward him. The last two-thirds of the Rosetta Stone relates how he will be honored, including erecting the Rosetta Stone, for all to read.

Another example of the hieroglyph usage is as adornments upon the hieroglyph for "shrine", and also for "buildings".
The Blue Crown
Before the New Kingdom Period, the body of the Uraeus coiled in around in circles behind its raised head on the Blue Crown. The king is most often depicted wearing the Blue Crown in combat and the aftermath of combat scenes. Additionally, the smaller scale king usually wore the Blue Crown when depicted in a protective group of deities. Colossal statues of the king wearing a Blue Crown are extremely rare; the typical royal statue also does not feature a Blue Crown. Also, depictions of the Blue Crown with its Uraeus does not decorate royal tombs until late in the Ramesside Period. The deity-on-earth king was thought to require extra protection in his mortal form, emphasizing the protective qualities of the Uraeus.  The Uraeus was usually crafted from precious metals, most commonly gold and less frequently silver, and adorned with gemstones. 
The angelic seraphim, found in the Hebrew Bible and later Jewish, Christian, and Islamic traditions, are frequently associated with serpents and are thought to have derived from the concept of uraeus. Multiple-winged uraei amulets are well represented in Palestine.
