and
Hathor from the
Harris Papyrus,
20th Dynasty (c. 1184–1153 BC)|right In the
Heliopolitan Cosmogony, Atum was considered to be the
first god, having
created himself, sitting on a mound (
benben) (or identified with the mound itself), and rose from the
primordial waters (
Nu). Early myths state that Atum created the god
Shu and goddess
Tefnut by spitting them out of his mouth. One text debates that Atum did not create Shu and Tefnut by spitting them out of his mouth by means of saliva and semen, but rather by Atum's lips. Another writing describes Shu and Tefnut being birthed by Atum's hand. That same writing states that Atum's hand is the title of the god's wife based on her Heliopolitan beginning. Other myths state Atum created by
masturbation, with the hand he used in this act that may be interpreted as the female principle inherent within him because the word for hand in Egyptian is feminine (
ḏr.t) and identified with goddesses such as
Hathor or
Iusaaset. Yet other interpretations state that he made union with his shadow. In the
Old Kingdom, the Egyptians believed that Atum lifted the dead king's soul from his pyramid to the starry heavens. thus describing the belief that the gods and goddesses would one day cease to exist outside of the primeval waters. In the
Book of the Dead, which was still current in the Graeco-Roman period, the sun god Atum is said to have ascended from
chaos-waters with the appearance of a
snake, the animal renewing itself every morning. Atum is the god of
pre-existence and
post-existence. In the binary
solar cycle, the serpentine Atum is contrasted with the scarab-headed god
Khepri—the young sun god, whose name is derived from the Egyptian
ḫpr "to come into existence". Khepri-Atum encompassed sunrise and sunset, thus reflecting the entire cycle of morning and evening. ==Relationship to other gods==
