About Raneb of Egypt (Kakau), Pharoah of Egypt
Raneb was a king during the Second dynasty of Egypt.
The Egyptian priest Manetho, calls Raneb Kaiechos and states that he ruled Egypt for 39 years but such a high figure is not confirmed from the few contemporary objects known from his reign. The king lists call him Kakau. Some scholars also read his serekh as Nebre, reversing the hieroglyphs. Manetho also claims that he introduced the worship of the sacred goat Mendes.
His name actually came from the name of the god Ra, also sometimes written Re, thus giving his name a meaning 'The Son of Ra'. His name Raneb translates as "Ra is the Lord."
Raneb was a son or brother of Hotepsekhemwy. Hotepsekhemwy's son was Perneb, who was either a nephew or brother of Raneb. It's possible that Raneb's son was Nynetjer.
The Egyptologist Jochem Kahl has recently concluded that a mysterious king Weneg, Wadjnes or Tlas in the kinglists was actually the Nebty name of Raneb.
Weneg is attested solely by inscriptions on stone vessels found in the Step Pyramid of Djoser and in Tomb S 3014. Weneg's exact chronological position, as well the identification of his Horus name among those known for the second dynasty kings has remained a mystery. But as Jochem Kahl observes regarding an inscription on a fragment of a stone bowl:
"A long-known inscription from Tomb P at Umm el-Qaab (Doc. 22) provides the key to solving some of the problems associated with Weneg. In the inscription the nsw bjt nb.tj name Nynetjer faces the opposite direction from the name of Ra'-neb and that of his palace (Fig. II. 2.1) Ra-neb's name is partially erased. Scrutiny of the inscription reveals that the name Nynetjer is written over Weneg. Traces of the plant sign used to write Weneg are discernible, as are the enigmatic strokes to the upper left and right of it (Fig. II 2.2) Thus Nynetjer must have been Weneg's successor, and the original inscription referred to the palace of Horus Ra'-neb and to nsw bjt nb.tj Weneg."
Therefore, Kahl concludes that the Horus name of Weneg must be king Raneb, the second ruler of the Second Dynasty of Egypt who was succeeded on the throne by Nynetjer.
