concerned with the regularly and perpetually recurring phenomena. Whatever may be the case in other mythologies, "I look upon the sunrise and sunset, on the daily return of day and night, on the battle between light and darkness, on the whole solar drama in all its details, that is acted every day, every month, every year, in heaven and in earth, as the principal subject"[1] of Egyptian mythology.
There can be no controversy about the meaning of Rā. Rā is not only the name of the sun-god, it is the usual word for sun. In other mythologies the sun-god is borne in a chariot or on horseback; in Egypt, his course across the sky is made in a boat. The sky (Nu) is accordingly conceived as an expanse of water, of which the Nile is the earthly representative. Rā is said to proceed from "Nu, the father of the gods." His adversary is Apap, who is represented as a serpent pierced with the weapons of the god. The conflict is not between good and evil, but the purely physical one between light and darkness. Shu and Tefnut are the children of Rā; Shu is Air, and Tefnut is some form of moisture, probably Dew.[2]
