Memphis, Egypt
In year 55 (ca. 1223 BC), Khaemwaset dies and following in the footsteps of his father and older brother Prehotep becomes High Priest of Ptah in Memphis, Egypt. Prehotep also takes on the position of High Priest of Ra in Heliopolis. That position he seems to have taken over after the death of prince Meryatum, the son of Ramesses II and Nefertari, who had been in office for almost 20 years. Prehotep held the positions of vizier and high priest of Ptah and Ra until the end of the reign of Ramesses II, thereby serving as vizier for at least 17 years and as high priest for at least 12 years.
