Thus instead of , one would write + . Different parts of the Eye of Horus were thought to be used by the ancient Egyptians to represent one divided by the first six powers of two: The Rhind Mathematical Papyrus contains tables of "Horus Eye Fractions". Studies from the 1970s to this day in Egyptian mathematics have clearly shown this theory was fallacious and Jim Ritter definitely showed it
Ancient Egyptian royal titulary were known only by this title. The Horus name was usually written in a serekh, a representation of a palace façade. The name of the pharaoh was written in hieroglyphs inside this representation of a palace. Typically an image of the falcon god Horus was perched on top of or beside it.
