This was the name given at birth. The name itself was preceded by the title "Son of Ra", written with the hieroglyph of a duck ("za"), a homonym for the word meaning "son" ("za"), adjacent to an image of the sun, a hieroglyph for the chief solar deity 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. For women who became pharaoh, the preceding title was interpreted as "daughter" also.
