Hence the Light-God is not the Sun-God, but his Antecedent and Creator.
The light appears in the East, and thus defines that cardinal point, and by it the others are located.

These points, as indispensable guides to the wandering hordes, became, from earliest times, personified as important deities, and were identified with the winds that blew from them, as wind and rain gods.

This explains the four brothers, who were nothing else than the four cardinal points, and their mother, who dies in producing them, is the eastern light, which is soon lost in the growing day.

The East, as their leader, was also the supposed ruler of the winds, and thus god of the air and rain.

As more immediately connected with the advent and departure of light, the East and West are twins, the one of which sends forth the glorious day-orb, which the other lies in wait to conquer.
