Ancient & Egyptian Roots
To the Egyptians the Sun was Ra, sailing the sky-boat by day and the Duat by night, reborn each dawn as the scarab Khepri. Kingship itself was solar — the pharaoh a living son of Ra — and the daily sunrise stood as proof that Ma'at, divine order, still held against the forces of chaos.
