[5] In 2012, Pierre Tallet and Damien Leisnay reported three rock inscriptions with Nebra's horus name found in the south of the Sinai Peninsula.

The places where Nebra's name is displayed lie along a very old route used for expeditions from the western shore of the Sinai to its inland, where copper and turquoise mines existed.

[6] Nebra's serekh name is of great interest to Egyptologists, since it is written with the hieroglyphic sign of the Sun, which had not yet become the object of divine adoration during his lifetime.

[citation needed] At the time of king Nebra, the most important religious cults were concentrated on the preservation of the dualistic equal status of the state patrons Horus and Seth.

The first definite proof of the existence of the Sun-deity Ra occurs at the beginning of the 3rd dynasty during the reign of king Djoser in the names of high officials such as Hesyre.

And the first definitive detectable proof for a fully established royal Sun cult occurs under king Radjedef, the third ruler of the 4th Dynasty.

The typical translation of Nebra's name as "Ra is my lord", which would be read "Raneb", is questionable, as this would assume that the Sun was already being worshiped as an independent deity.

This links to the anecdote written by Manetho, who said that under king Kêchoós (the Greek version of the name Kakau) the deities Apies, the goat of Mendes and Menevus were "introduced and worshipped as gods".

He points to a vessel fragment made of volcanic ash, which was found in the tomb of king Peribsen (a later ruler during the 2nd dynasty) at Abydos.

[12] Kahl's theory is the subject of continuing discussion since the vessel inscription is damaged, thus leaving plenty of room for varying interpretations.

[citation needed] Other pot inscriptions and seal impressions surviving from his time only name cult-related and administrative events, such as the "Erecting of the pillars of Horus".

Egyptologists such as Wolfgang Helck and Peter Munro believe that Nebra was buried in the gallery tomb B beneath the causeway of the Pyramid of Unas at Saqqara.
