Khentakawess III is believed to have been the wife of Pharaoh Neferefre, who ruled Egypt 4,500 years ago.
Spanish archaeologists have discovered a millennia-old mummy in “very good condition” near the southern Egyptian town of Luxor, the antiquities ministry said.
The find was in a tomb probably dating from between 1075-664 BC on the west bank of the Nile river, 700km south of Cairo, a statement said on Sunday.
The mummy had been bound with linen stuck together with plaster.
It was in a brightly coloured wooden sarcophagus and had been buried near a temple from the era of fourth-millennium warrior King Thutmose III.
The tomb was likely to have belonged to a nobleman, Amenrenef, who was “a servant of the royal household”, the antiquities ministry said.
The archaeological team’s head, Myriam Seco Alvarez, said the mummy was decorated with “many colourful decorations recalling religious symbols from ancient Egypt, such as the goddesses Isis and Nephthys displaying their wings, and the four sons of Horus”.
The earliest evidence of mummification in Egypt suggests the practice of wrapping bodies to preserve them after death dates back as far as 4500 BC.
Luxor, a city of half a million people on the banks of the Nile, abounds with temples and tombs built by Egypt’s pharaohs.
It is a key site for Egypt’s tourist industry, which has been battered by political instability and violence since the 2011 revolution that toppled then-president Hosni Mubarak.
