In Egyptian mythology, the scarab-headed god who represents the rising sun is Khepri.
Khepri was connected with the morning sun, rebirth, creation, and renewal. His name derives from an Egyptian verb meaning “to come into being” or “to transform,” making him a natural symbol of the sun's daily rebirth. He was commonly depicted as a scarab beetle, a man with a scarab for a head, or a scarab pushing the solar disk.
Ancient Egyptians observed scarab beetles rolling dung into balls and later emerging from them. They interpreted this behavior as evidence that the beetles generated themselves, linking them with spontaneous creation and the sun's emergence at dawn. In the nightly solar cycle, the sun god's journey through the underworld culminated in rebirth at morning.
Khepri was one aspect of the sun god's daily cycle. Ra represented the sun during the day, while Atum was associated with the setting sun and the completed, aging form of the solar deity. Thus, Khepri is not simply another name for every solar god: he specifically embodies the renewed sun rising into the morning sky.
