A British Egyptologist has found new evidence suggesting the death mask of ancient Egyptian king Tutankhamun was not made for him – in fact, it was made for his stepmother, Queen Neferтιтi.

Egyptologist Nicholas Reeves told Egyptian news service Ahram Online the famous gold death mask of Tutankhamun was in fact never intended for him.

Dr Reeves points to a cartouche (royal name stamp) that appears to have been retouched as evidence. The stamp conceals traces of another name: Ankhkheprure Nefernefruaten, which can be translated to Queen Neferтιтi.

“Blinded by the piece’s sheer beauty and enormous bullion worth… the world has looked and yet has completely failed to see – that the gold mask had never been intended for Tutankhamun at all,” said Dr Reeves, who was a curator in the former Department of Egyptian Antiquities in the British Museum

Other features that back his conclusion the death mask was intended for a woman include the presence of pierced ears. In almost all other ancient Egyptian depictions, pierced ears were a feature only reserved for queens and children.

The discovery was made possible by an accident involving the mask’s beard being broken off and hastily glued back on by an employee of the Egyptian Museum in January.

The botched repair job led to the mask being taken off display for restoration, and for the first time, it was examined meticulously and pH๏τographed.

“A fresh examination of the mask in Cairo at the end of September 2015 yielded for the first time, beneath the hieroglyphs of Tutankhamun’s praenomen (personal name), lightly chased traces of an earlier, erased royal name,” said Dr Reeves.

This is the second time this year Dr Reeves has shaken up the archaeological community. In October, he studied ultra high-resolution images and believed he found clues in the walls of Tutankhamun’s burial chamber of having been painted over with scenes depicting the young Pharaoh’s life, as well as hidden doors that may lead to the discovery of Neferтιтi’s final resting place.

Egypt’s antiquities authorities received the news with enthusiasm, and have approved the use of ground-penetrating radar to probe the tomb after a preliminary infra-red scan of the walls last month appeared to back Dr Reeves’ claim up.
