The eye is related to the concept of light and light energy. The left eye of Horus is related to the Moon, while the right eye is identified with the Sun and is the defender who is on his forehead.
In this case we are faced with the personification of the eye of the solar god, who had the power to be independent of the god, but who preserved him from evil.
Eye of Ra Meaning
This goddess could take the form of a cobra or that of a lioness-headed woman. Said protective cobra was placed on the forehead of the god Ra and on that of the sovereign as a symbol of power and defense.
The legend tells how the Eye (personified in a goddess Hathor-Sekhmet) emerges from the god Ra himself and, angered by the treatment that humans have given her father (the sun) travels furiously to Nubia to take revenge on men and annihilate them in her path.
Realizing the disaster she is causing, Ra orders her to cease the killing, but she, enraged by the taste of blood, does not listen to his pleas.
That is why the sun has to summon the gods and order a divine commission to leave in search of his Eye and order her to return to her place.
When they find her they try to placate her with music and dances, and they decide to intoxicate her with a red drink, made up of fermented madrasses, which they pour on the ground.
Upon awakening, the goddess drinks in abundance and completely drunk calms her spirits, Thus the gods manage to take her to Egypt where she washes in the waters of the first waterfall of the Nile River (related in this case with the primary waters) and becomes a beautiful woman.
After being received in several religious centers with signs of joy, Ra turns her into Uraeus and places her on his forehead so that she can never escape again.
This myth is collected for the first time in the Tomb of Seti I in the Valley of the Kings and later, with different variants, is repeated in the Ptolemaic temples, also being documented in Greco-Roman era papyrus.
In any case this legend varies depending on the version of the myth that is consulted. Thus, in some places the person responsible for the return and appeasement of this deity is the god Thoth, while in other texts it is Anhur (Onuris), Shu and Tefnut, etc.
In all cases, the person responsible is accompanied by a whole procession of minor gods, geniuses and musicians who, through their songs and the sound of their instruments, soothe the angered goddess and bring her back to her father Ra who places her on his forehead: Uraeus form.
