A son of Djedefra was actually named Baka, his name was indeed written with a ram- and a ka-symbol. It might be possible that prince Baka was meant to become king on the royal throne, but then he died unexpectedly during his coronation year, leaving an unfinished tomb shaft. Maybe Baka changed his name from "Baka" into "Baka-Re" after his coronation, or perhaps it was done posthumously. If the theory is correct, Bikheris was the hellenized variant of Baka(re). Historical figure Some scholars suspect that the line of throne successions during the 4th Dynasty of Egypt may have been much less smooth than mainstream Egyptologists believe. In support of this, they point out that it was already suspicious that king Djedefra broke with the family tradition of building royal tombs at Giza. In fact, Djedefra had left the Giza necropolis in an attempt to found a new royal cemetery at Abu Rawash instead. Alan B. Lloyd also points out that Djedefra dared another break with royal traditions by introducing the cult of Ra and placing Ra over all other deities. If Djedefra broke with family traditions, then Bikheris, as his son, may have done the same thing. This, and the obviously very short reign, may have led to Bikheris' exclusion from official records. Another problem is how later historians depict the 4th Dynasty: Manetho and Eratosthenes both describe Bikheris as the sixth ruler of the 4th Dynasty and as the son and successor of king Djedefra. However, both authors chronologically misplace the kings completely since they give the succession Snofru → Khufu → Khafre → Menkaure → Djedefra → Shepseskaf → Thamphthis; archaeological records however give the correct succession Snofru → Khufu → Djedefra → Khafre → Menkaure → Shepseskaf. The reason for the numerous misplacements of kings in Hellenistic documents may be caused by the ancient authors' erroneous idea that the three builders of the Giza pyramids (Khufu, Khafre and Menkaure) automatically must have been direct throne successors. Also, the Hellenistic authors seem to have built the king list on the historical importance of each king: first the "famous pyramid builders" everyone knew at their time (because of their still practiced mortuary cults and their impressive monuments), then the "lesser important" followers. Thus, most scholars are convinced that Bikheris, should he have existed, must have ruled either between Djedefra and Khafre, or between Khafre and Menkaure. Since Bikheris is
