This was the name given to the pharaoh at birth. The name itself was preceded by the title "Son of Ra". This was written with the hieroglyph of a duck ("za"), a homonym for the word meaning "son" ("za"), next to an image of the sun, a hieroglyph god Ra. It was first introduced to the set of royal titles in the Fourth Dynasty and emphasizes the king's role as a representative of the solar god Ra. When the pharaoh was woman, the preceding title was interpreted as "daughter".
