Nebra or Raneb is the Horus name of the second early Egyptian king of the 2nd dynasty. The exact length of his reign is unknown since the Turin canon is damaged and they credit Nebra with either a 10- or 14-year rule. According to different authors, Nebra ruled Egypt c.2850 BC, Nerbas name appears on several stone vessels, mostly made of schist, alabaster and marble. Most of the bowls were found at Abydos, Giza and Saqqara, the inscriptions contain depictions of cultic buildings such as the Ka-house, depictions of deities such as Bastet, Neith and Seth and also the mentionings of cultic feasts. Interestingly, all objects present Nebras name either together with that of his predecessor Hotepsekhemwy or with his successor Nynetjer. Clay seal impressions with Nebras name were found beneath the causeway of the Pyramid of Unas at Saqqara and inside a gallery tomb. This tomb also yielded several seal impressions with Hotepsekhemwys name and for this reason it is debated whether the tomb belongs to Nebra or his predecessor Hotepsekhemwy, in 2012, Pierre Tallet and Damien Leisnay reported three rock inscriptions with Nebras horus name found in the south of Sinai peninsula. Each rock inscription can be found in a different wadi, Wadi Abu Madawi, Wadi Abu Koua and Wadi Ameyra. The places where Nerbas name is displayed lie along an old route used for expeditions from the western shore of the Sinai to its inland. Along the wadis the names of predynastic kings up to pharaohs of the 4th Dynasty are located at the same places. Nebras serekh name is of great interest to Egyptologists, since it is written with the sign of the sun. At the time of king Nebra, the most important religious cults were concentrated on the preservation of the equal status of the state patrons Horus. Nothing was more important than keeping that divine balance, the kings themselves were seen as the living representation of that godlike pair. The sun was seen as a celestial object controlled either by Horus or, as in the case of king Seth-Peribsen, therefore, the sun was no independent deity yet. 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 officials such as Hesyre. And the first definitive detectable proof for an established royal sun cult occurs under king Radjedef. He was the first king who connected his name with the name of Ra, starting the great religious belief that Egyptian kings were the living representation of the sun alongside Horus. Therefore, Nebras Horus name is problematic regarding its translation and meaning, the typical translation of Nebras 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
