Mutbenret
Mutbenret (Benretmut) was an Egyptian noblewoman, and said to be the Sister of the Great Royal Wife Nefertiti. Her name used to be read as Mutnedjemet. The hieroglyphs for nedjem and bener are similar and so is their meaning. The name is now thought to be Mutbenret however.
One theory holds that Mutbenret was the same person as Mutnedjmet the wife of Horemheb, the last ruler of the Eighteenth Dynasty. But there is no conclusive evidence for this theory, and some challenge this theory.
Mutbenret appears in several of the Tombs of the Nobles at Amarna:
In the tomb of Panehesy (tomb 6) the presence of two dwarfs on a lintel in a register associated with an offering scene indicate that Mutbenret was depicted nearby (probably in a register next to the royal princesses).
Mutbenret is depicted behind the royal princesses in the award scene for Parennefer (tomb 7).
Mutbenret is depicted in the award scene for Tutu in tomb 8. In the register below the King and Queen we see the Queen's Sister Mutbenret with her two dwarfs, several fan bearers and the nurses of the Princesses.
