Amun-her-khepeshef
Not to be confused with Amun-her-khepeshef, a son of Ramesses III, and Amenherkhepshef, a son of Ramesses VI.
Amun-her-khepeshef or Amonhirkhopshef or Amun-her-wenemef was the firstborn son of Pharaoh Ramesses II and Queen Nefertari.
Amun-her-khepeshef (20th dynasty)
Amun-her-khepeshef was the eldest son and appointed heir of Pharaoh Ramesses III. Like many of his brothers, he was named after a son of Ramesses II, Amun-her-khepeshef. He died when he was about fifteen years old.
He is also mentioned as Ramesses Amun-her- khepeshef. He is not identical with his brother Ramesses VI, who was also called Amun-her-khepeshef before he became pharaoh.
He is depicted in his father's temple at Medinet Habu. His well preserved tomb, QV55 (in the Valley of the Queens) was excavated by Italian archaeologists in 1903-1904.
