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
Horus called themselves "followers of Horus", and Horus became the tutelary deity of the unified nation and its kings. Yet Horus and Set cannot be easily equated with the two-halves of the country. Both deities had several cult centers in each region, and Horus is often associated with Lower Egypt and Set with Upper Egypt. Other events may have also affected the myth.
