Goddess of the Sky
One of the oldest Egyptian goddesses, the goddess of the sky, is the body beneath which the universe is submerged. She is the wife of the god Geb, and gave birth to the sky and the earth with four children, forming the fourth generation, namely, "Osiris", "Isis", "Set" and "Nephthys".
Nut was often depicted in human form, but sometimes as a cow or a tree. Her epithets include “She Who Covers the Heavens,” “She Who Protects,” “She Who Carries All the Gods,” and “She Who Carries a Thousand Souls.”
Other popular concepts see the sun as a child stepping into the mouth of the sky goddess Nut in the evening, then passing through her body during the night and being reborn from her in the morning, and sometimes as a young child of the sky goddess who is embodied in the image of the heavenly cow.
There was also a mixture of these different conceptions of the daily journey of the sun god, and it is not surprising that the story of the destruction of mankind is inscribed with a picture of the god Ra in his full human form sailing in his sacred boat on the back of the sky cow Nut.
The idea of the sunset as being swallowed by the sky goddess extends to the movement of the stars in the sky, which are seen as little pigs disappearing into Nut's mouth where she devours them in the morning, then brings them out again before nightfall. For this reason the word Mesut in Egyptian literally means "time of birth."
As in the Heliopolis myth, the universe originated from unformed water called Nun, from which emerged the god Atum, who appeared on a hill called the First Hill or the Hill of Creation - and the god Atum is equal to the god Ra - then the god Atum created the twins Shu, the god of air, and Tefnut, the goddess of moisture, who in turn created the god Geb, the god of the earth, and the goddess Nut, the goddess of the sky.
