The Egyptian God Shu was the God of Air. Basically he was everything between the earth and sky (who are also his children).

He was what held up the sky (his daughter) up above the earth (his son) with his own hands. Without this heroic and eternal act of separation, creation would not have been possible.

He is also thought of as the god who brought light to the world after the darkness and chaos that was the primordial state.

Symbolically, his form was that of a man with a feather on his head. The feather represented the lightness of air. And part of being the god of air, he represented northern wind and cool breezes.
