In later Egyptian dynastic times, Ra was merged with the god Horus, as Re-Horakhty ("Ra, who is Horus of the Two Horizons"). He was believed to rule in all parts of the created world: the sky, the earth, and the underworld. He was associated with the falcon or hawk. When in the New Kingdom the god Amun rose to prominence he was fused with Ra as Amun-Ra. wikipedia
